What do doctors add in the medicine that contains antibodies in a syringe?
I might have misunderstood your question... but if you mean excipients (agents that are added to improve stability of the active ingredient or to maintain it in solution) then you can find quite a lot of information on the electronic Medicines compendium if you know the name of the vaccine. The website is http://emc.medicines.org.uk and once you've typed in the name of the vaccine, choose the link with the letters SPC (which stand for Summary of Product Characteristics) next to it, and browse the excipients section (I think it is always section 6.1). This works for UK medicines, I don't know what other databases there are, but Google might have the answer. Hope that helps, Jo Brodie, 16:49 BST, August 30, 2005.
This is a peculiar question and I suspect represents a misunderstanding or a non-Western practice. It is extremely rare for American or western European doctors to give injections of antibodies in a syringe. Antibodies in the form of gamma globulin are given by iv infusion for many problems but this doesn't involve a syringe. I cannot off the top of my head think of any examples except old fashioned passive immunity treatments for rabies, tetanus, and snakebite antivenin. There are a number of newer monoclonal antibodies used as treatments for specific uncommon conditions, but most of these are still experimental research protocols and most are given by infusion rather than injection. There were some quack cancer treatments involving injections in the past which claimed to induce a patient to make antibodies against the tumor, but these were pretty uncommon. Can you give us more context? What disease is being treated, and in what country, and is the doctor a mainstream MD or alternative practitioner? alteripse 16:19, 30 August 2005 (UTC)

Luminous toxin is a descriptive term for an actual poison.'' — Technical Adviser, Edward F.

Explain why in a group of 35 children at a school, a randomly selected individual has a high probability of being the oldest son or daughter in his or her family.
--anonym
Presumably this is a math assignment. If the average number of children per family are less than 2 (as is true in most of the western world), any randomly chosen child is more likely to be an eldest than a non-eldest.
Average children per family (CperF) can be expressed as N1+N2+N3+N4+N5+N6...+N20 divided by the NF, where N1 is total number of eldest children, N2 is total number of second children, N3 is total number of third children, etc, and NF is the total number of families. There is a value of CperF below which more than half of any group of children are eldest (N1). Is this what you are supposed to compute? It would be somewhat above 2 because preschoolers (age under 5 years) would be selectively excluded from your classroom sample.
Unless King Herod or the Tenth Plague of Egypt has visited the community lately, there will always be more eldest children than second, more second children than third, etc (i.e., N1>N2>N3...N20), so that even in a society in which there are on average many children per family (high CperF), any randomly chosen child is more likely to be an eldest than a second, third, fourth, etc. alteripse 11:16, 31 August 2005 (UTC)

As someone who has spent entirely too much money in lifetime paying Dentist bills, and now 100% false teeth, it seems to me the battle was to save what was left of eroded teeth until I was willing to part with the last of them. In children there is something called wisdom teeth, in which something grows, comes out, then is replaced with another, but in my adult experience, once you got a damaged tooth, or a cavety, the dentist can patch it up, but there is no "natural" cure. AlMac|(talk) 07:18, 30 August 2005 (UTC) I'm not sure what you mean about the wisdom teeth? --Phroziac (talk) 16:58, September 3, 2005 (UTC) Children will exchange their milk teeth, but after that your teeth won't grow anymore. I speak from experience as two people in my family had broken front teeth. The dentist patched it up with fake teeth or fake partial teeth, but once damaged, adult teeth can not recover. In fact, once you've exchanged your teeth as a kid, your new teeth won't grow anymore. They're already adult size. - Mgm|(talk) 08:37, August 30, 2005 (UTC) Humans only get two sets of teeth - their milk teeth and the adult set, though the wisdom teeth at the back may not appear until you're in your twenties and (in my case) have to come out straight away. If you damage your adult teeth, that's it, you're stuck weith them - they don't grow any more. -- Arwel 12:24, 31 August 2005 (UTC) Which I can, unfortunatly, confirm from my own exprerience.

The Earth is pretty rough at that scale - you have mountains, seas, that sort of thing - which are very inhomogenous; it'd be like dealing with a lot of weird mascons. (Consider the gravitational effects of "ring next to a mountain" vs. "ring over central Pacific). It'd probably "crash to the ground" somewhere along the length - or, indeed, buckle under its own weight and do so all over the place. Shimgray 19:55, 30 August 2005 (UTC) It wouldn't be very stable unless you spun it, but you could make it a geosynchronous orbit. You might want to look at Ringworld and Dyson sphere. Bovlb 19:59:37, 2005-08-30 (UTC) At geosynch you might manage stable, but not at a kilometer high - local mass differences are just too significant, then. Shimgray 20:33, 30 August 2005 (UTC) You might also find an interest in the space elevator concept. How is that supposed to stay where it is supposed to be? AlMac|(talk) 06:08, 31 August 2005 (UTC) The plan for that is to be above geosynchronous orbit (much much more than 1 km above the surface). Technically it would work at geosynchronous orbit, but the designers want the elevator structure to be under some tension. The ring structure would "hover" at geosynchronous orbit, except that our geoid isn't perfect and we've dumped lots of satellites up there, so I don't think it'd be particularly stable, but — as mentioned above — spinning it up would help. — Laura Scudder | Talk 15:49, 31 August 2005 (UTC) I believe the general concept is to counterweight an elevator so that the center of gravity is at the geosynch point.

A "descriptive term for an actual poison" means thay are describing the toxin rather than giving you its name. Medical articles will refer to it by its actual name.

Theresa Knott (a tenth stroke) 19:30, 31 August 2005 (UTC) Expect a 40's film to be very loose with scientific merit. Very roughly, you could describe phosphosous as a luminous toxin. White phosphorous, specifically, glows and is a systemic poison, although mostly known for bone damage. This was probably close enough for the purposes of a sensational movie script. However, having several days of relative health before dying (despite the best medical intervention) is possibly more charactistic of overdose from paracetamol or deadly Amanita mushrooms, both of which cause liver failure that results in death after an initial recovery 131.172.99.15 (talk) 12:44, 23 December 2008 (UTC)snaxalotl Without a reliable citation, phosphorous or one of its compounds is just a guess.

Power and torque output (of WRC cars)

How can the engine develop such a high amount of torque considering that the power output is not that high? Isn't there an inconsistency between the figures? Am I just miscalculating or how is this possible? Thanks, --Ozkaplan
According to the article on torque, if P P is power in kilowatts, T T is torque in Newton metres, and R = rotational speed in revolutions per minute, if you manipulate the constants: P = T × R × 2 π 60000 {\displaystyle P={\frac {T\times R\times 2\pi }{60000}}} If you plug in T = 635 and R = 4000 into that I get approximately 266 kilowatts, which is about 357 horsepower. Considerably over the limit, still. As to how it's done, let's just say that creative interpretations of physics, mathematics, and indeed logic pertaining to rulebooks have been a stock in trade of automobile racing for a very long time. In the 1980's, the maximum level of turbo boost in Formula One was supposed to be restricted by the use of a standard popoff valve, which opens up to bleed off pressurised air if the pressure gets too high. Teams apparently got around this by fitting huge turbos to their qualifying motors which pumped so much air the popoff valve couldn't get rid of it all...--Robert Merkel 12:18, 31 August 2005 (UTC) computers Edit

Most statistics books seem to be written by people who lack basic descriptive skills or have yet to have agood grasp of English writing. Here we see a statistic textbook explaining cummulative frequency, a complex name for an extremely brain-dead operation, and explains it with great complexity:
"A cummulative frequency distribution can be created from a frequency distribution by adding an additional column called "Cummulative Frequency." For each score value the cummulative frequency for that score value is the frequency up to and including the frequency for that value."
Is there any books, or other sources anyone can recommend to me that will not try to complicate this very simple subject?

In case that was slightly confusing what i mean to ask is that gravity is a single point in the exact centre of our planet so if there was just an open void around that point and something was placed on that point would it just float exactly still as forces are acting equally uopn it in every directon?
Thanks for the answer but it leads me to another question. If every part of the earth produces a gravitational pull and these minute pulls combine to form what appears to be one force known as gravity why is it that we are not pulled slightly towards huge clusters of particles like say a mountian and also why is it that all of these forces seem to pull towards one point in the centre of the earth?
Oh and your comment about getting closer to one side of the sphere and the force growing stronger but the lack of particles meaning they even each other out. What is that supposed to mean? These particles that are fewer as you move closer to one side, are they supposed to be air particles because thats the only thing i can imagine moving through as easily as you say. And even each other out!!?? If the forces evened each other out wouldn't you be stuck in your position unable to move unless you can produce a force strong enough to move in a direction?
One more thing, if 'particles' of whatever it is are responsible for gravity then is a black hole just an unspeakable number of them clustered together?
Thanks guys

Hello, everyone. I am writing to ask about something that I saw last night. After a rather grand storm, in which all light faded, suddenly not only the sky above, but all the space outside, became a disorientating, deep chemical yellow (see the picture to the right). Walking outside was like walking into yellowness. After about twenty minutes, during which time the yellow became darker, the light shut out, and we were in total darkness. I have never before witnessed such a thing. Do you know what this occurance is called, and what causes it? I would appreciate any help. IINAG 13:08, 1 September 2005 (UTC)
I occasionally play a little with Linux on my GameCube. For that, I have a 1GB harddrive image for use with a Network Block Device server.
However, I occasionally wish to manipulate this image without having to boot the Cube into Linux - injecting files, etc. Does anyone know if there are any tools that will let me do this? It doesn't matter if the image is mountable as a drive, or if I need to use a seperate program that mounts the image internally. -- Pidgeot (t) (c) (e) 13:35, 1 September 2005 (UTC)
Is there any simple (free) way of transforming a word document to a pdf? I tried converting to OpenOffice, but their pdf converter makes the document ugly. Why doesn't Word have its own converter?
Thanks! --Alice
Hi all, thanks for your replies.
I tried Pidgeot's suggestion and it seemed to work well. However, it changes the formatting o my document. I've got a 40+ page paper, with chapter headings at the tops of pages and References at the end. There appear to be a different number of lines per page in the pdf, which makes my headings appear in varying places down the page, and the references after 1 1/2 blank pages. How can I get it so that the formatting is the same as in my word document (and yes, I'll learn latex for the next paper!).

I'd go for taste if it wasn't for the potentially deadly results. If you disolve it in water and it the water can now transfer electricity it's a salt. If you smell cloride it's a cloride salt. You can then add other water solutable salts to test whcih to ions the salt was composed of (look in the chapter Salts in your chemistry book for the exact procedure). -- R.Koot 03:55, 2 September 2005 (UTC)

Also flame test and borax bead test. These will help identify the substance, if only to show what it isn't, since some substances do not give helpful results. Melting point is another useful tool, as well as density.
Hi, I know this might not be technical enough to warrant your attention but do you happen to know the exact speed of sound in MPH, KPH and Knots? I know its around 750MPH but i need to be sure in order for my calculations to be correct. Ryan
In that case can you tell me which sequence of variables they use to determine the top speed of planes ie. If a company states it's plane can go Mach 2 then which speed are they referring to as it could be anywhere between 1200mph and 1400mph?
Just to complicate things, note that a plane (a jet, as prop plane are always subsonic, I think) will go faster in rarefied air, because of reduced friction, but sound will tavel slower in that medium. There is a law of diminshing returns here, as rarefied air will provide less oxygen to the jet engine and it will produce less power.
Hi,
I recently read an article on a similar site that stated; if you were on a train travelling at 1000mph (and the ride was so smooth you couldn't notice) and you fired a bullet off the front of the train (in the exact direction it was travelling) then the bullet would be travelling at 2000mph relative to a stationary point on the ground and at 1000mph realtive to your position (moving at 1000mph). This I can believe, but it also states that if you fired a bullet under the same circumstances off the back of the train (this is all theory, I'm not taking into account aerodynamics or anthing) that the bullet would be travelling at 2000mph relative to your position on the moving train but it would be travelling at 0mph in relation to a stationary point on the ground. This suggests that the bullet would float in that air on then just fall to the ground. Is that correct because it seems very unlikely?
Thank you to R.Koot and StratOnLSD (interesting name) for those answers, and to Notinasnaid; I believe if you read my question you would understand I was disregarding any other forces, variables and factors not covered in my question and if technicality is your specialty (which it appears to be) then you shouldn't have answered a question about a train moving at 1000mph.

I got stumped working on the Elbow macaroni article. They make macaroni by extruding dough through a circular die with a pin blocking the center of the circle. I see a number of references that say that a "groove" in the pin causes the pasta to curve as it is extruded. How? What does this groove look like? Why doesn't it form a ridge or valley on the finished product? Bunchofgrapes 17:11, 2 September 2005 (UTC)
It has to do with relative rates of extrusion. Pasta machines work by forcing pasta dough through a die, which simplistically speaking is just a negative silhouette of the desired shape. But if more dough is forced through one part of the die than another part, the extrusion there will happen faster, and the extruded pasta will curl.
A picture will make this much clearer.
Here is the front view of an elbow macaroni die:
This is about 30cm in diameter, and as you can see it extrudes 5 tubes of pasta at once.
But now let's look at the back:
The ridges you see divide the total output of the pasta machine
(that is, the stream of pasta dough which this die is the target of)
into ten "capture regions".
(There's a rather nice analogy here to
watershed.)
Two regions flow into each extruded macaroni tube,
but significantly, one of them (the outer one) is considerably larger than the other.
Therefore, the outer edge of each tube will extrude faster than the inner, and each one will therefore curl inwards.
I haven't seen one, but I presume that the die for curly-edge lasagne consists of the long straight slit you would expect, but with some extra "capture region" at each end of the slit (corresponding to each edge of the lasagne ribbon). In this case, the extra dough volume is too localized to cause a curl, but it has to go somewhere. The edges end up being "too long" for the main body of the ribbon, so the edges end up rippling to consume the extra material.

A slot machine has three wheels: Each wheel has 11 positions – a bar and the digits 0, 1, 2,…, 9. When the handle is pulled, the three wheels spin independently before coming to rest. Find the probability that the wheels stop on at least one bar.
I have two answers. I think the first one is right, but I do not understand why the second one might be wrong.
P(E1) = , where I subtract the probability of getting no bar three consecutive times (10/11)3 from 1.
P(E2)= , where I add the probability of getting one bar, two bars, and three bars.
Can you explain this discrepancy? Why do these two answers not conform to each other?
--anonym
To expand on Y0u's answer. The probability of getting one bar is
i.e. the probabliity of a bar on the 1st multiplied by a not bar on the other two multiplied by three (because the bar could be on any of the three not just the first one).
Likewise the probability of two bars is

Nope. For P(4 games) you need to have one of the two teams win all four games in a row. (There is no other way it can happen). Call the teams A and B. So I reckon (and I'd like people to check my reasoning please) that
Where means the probability that side A wins game 1 and so on.
Now all these probablilities = 1/2 so that gives P(4 games) = ?

To whom this may concern,
I am typing this question to you hopping that i will be takin seriously. I have taken a course in collage on chemistry, and have started to take an other course in solar systems. When i sat down i took a look at a cell make up and looked at the whole solar system. if you look at them they do have a similar look to them. Now the only difference that i can make out is that the levels of electrons on the solar system does not consist of the same law.... or does it. when we look at a cell through a microscope we shed light to the whole area of the cell. Now if we where to take that light and project it on an angle or completely to it's side would the electrons cast a shadow to the other electrons and unable us to see the other electrons needed make the cell function to what our law says. Now if we think of the Solar System the sun sheds light on an angle causing a cone shaped shadow hiding the "other planets/electrons". Also as we all know all means of life needs wheather it be light, water, oxygen, other living things... Thinking of electrons what if they needed light to be at its full ability to function so the the cell was able to split? if so what if it needed that light for a certain amount of time to make it visble to the eye weather it beeing seen through a microscope looking at a cell or lookin thruogh a telescope looking out at space. With all this my question is are us humans on a cell called the solar system?
P.S. If you could kindly help me clear my mind it would be greatly appreatiated.
Thank you

Hey, everyone,
So, once again, abusing this source of Internet knowledge in lieu of a technical support service - I have a desktop and a notebook that I'd like to network together via a crossover cable (modified Ethernet cable - everyone know what I'm talking about?). The trick is, my desktop has an Ethernet cable plugged into it most times, which connects it to the Internet via my college network. In order to connect to the college network, there are all sorts of configurations I have to place on the connection. So many, in fact, that if I switch the Ethernet cable for the croosover cable to my laptop, I have to reconfigure the connection back to its original settings, which takes forever.
Here's my question: is it possible for me to set up a network between my laptop and my desktop, which ONLY comes into play when I connect them via the crossover cable? And is there any easy way to go back to the settings the desktop needs to connect to the college network? Both computers, by the way, use Windows XP.
Well, I hope at least some of the above is understandable. If any clarification is required, all you have to do is ask.

Hey, everyone,
I'm a science fiction writer trying to cobble together a concept. Any scientists out there, would you tell me if there is anything extraordinarily stupid about what I'm about to suggest? - Radiation is, when you get right down to it, just a group of rogue particles created or emitted by a substance undergoing decay - either accelerated, in the case of fission, or slow, as in standard radioactive decay. So since radiation is a particle, it should be technically possible to filter out radiation on an atomic level through nanotechnology. I'm thinking of what basically looks like the quantum equivalent of the Strategic Defense Initiative - something that spits out a particle to deflect or destroy the radioactive particle. Or maybe a better idea would be a quantum-sized "filter" that lets in some particles but not others; basically acting as a net that lets larger particles through but grabs the radioactive particles. -- Brasswatchman 23:15, September 6, 2005 (UTC) So, where am I wrong? Thanks. -- Brasswatchman 21:14, September 5, 2005 (UTC)
How are you going to destroy the particle? You could annihilate it with it's antiparticle but the energy would still be there in the form of gamma rays. You can stop gamma rays with matter. A bloody great lump of lead should do the trick - bit that's probably too crude for you.
Some sort of net? The thing about radiation is that it is ionising Maybe your net could be transparent when neutral but turns opaque when it's ionised. Theresa Knott (a tenth stroke) 22:04, 5 September 2005 (UTC)
Well: (1) not all radiation is particulate (ie, massive particles); (2) even the "biggest" (most massive) particle radiation—the heavy cosmic rays—are only atomic nuclei, whereas nanotechnology is at the scale of cells or big molecules; (3) SDI presupposed a method to detect and track ICBMs from launch, but you have nothing analogous to that at the nuclear level; (4) even if, somehow, you managed to annihilate a cosmic ray, you now have gamma radiation carrying the combined energy of the original particle and your magic bullet; (5) it is misguided to say that particle radiation is composed of "radioactive" particles, since most of it is perfectly stable atomic nuclei or free electrons; (6) "quantum-sized" is not a definable term. I hope this helps. Sharkford 22:06, 5 September 2005 (UTC)
Just remember that sometimes sci-fi is more enjoyable (even for scientists) when it leaves how things work to the imagination rather than trying to cobble together an explanation from jargon.

Is Banana peel actually especially slippery?
Yes. As the outside of a banana peel (the more yellow side) is actually quite sticky (try rubbing your hand across it - there's a lot of friction there), and the whiter inside has (when still moist) a very low coefficient of
friction, when you put your foot on the peel, the friction of the yellow, outer side ensures your foot will stay on the peel, while the slippery inside will ensure you slide across the floor, and usually fall over.
However, for this to happen, three things need to occur: 1) The peel must have the slippery (inside) side on the floor, and the yellow outer peel facing upwards. 2) The floor the peel is on must be hard and relatively smooth (ie, a polished or tiled floor). 3) The peel must still be moist (ie, not been there for a while.
So yes. A banana peel is especially slippery. Proto t c 13:08, 7 September 2005 (UTC)

hello!
I am a Year 9 student at Tonbridge grammar school for girls and i am doing a project and i am in need of your help!
i am trying to find out between the differences and similarities between the following:
neon and argon neon and francium
i would be grateful if you could give me a list of the similarities or point me in the right direction of finding the answers.
thank-you charlotte

Note that both of these elements have no stable isotopes even though the ones next to them do.
Also note that if the Rare Earth (Lanthanides) are extended in place of the third period of the transition elements, Promethium appears right under Technetium. Also note that both atomic numbers are prime numbers whereas Manganese is not. Some discussion of if this is just coincidence or if there is a story to tell there would be interesting to me.
I dont' know what you mean by 'proper' A 'proper' arrangement of the elements is just as it is now, with the Rare Earths in their own group. I am suggesting an 'improper' arrangement, but one which is not random check this out.
http://en.wikipedia.org/wiki/Periodic_table
If you put Lanthanum under Yttrium, Cerium under Zirconium, et al, Promethium is under Technetium. Coincidence? Maybe. Awfully odd that the two light (relatively) unstable elements line up like that.

The value of log2 is 0.3010, that of log20 is 1.3010 and that of log0.2 should be -1.3010
Is the above statement correct? When I checked up the value of log of fractional nos. (> 0 and < 1 I get wrong answers in Scientific calculators, MS Excel formula etc.
Whys is this so?
can I get a reply to my email ID vaidyaguru@yahoo.com or vaidyaguru@gmail.com

Hello,
My name is Adam Rogers and I live in Conway, AR. On a roadtrip yesterday I noticed a horizontal black line which spanned the distance of the sun and no other parts of the sky. There were no clouds and no jet trails, even had there been they would not have blocked the sunlight in such a fashion. The occurence I observed lastted about 15 minutes and the black line followed the size of the sun from top to bottom as the line rose upwards across the sun. If anyone has seen a black horizontal line on the sun before or has any explanation as to why my eyes would have perceived such a thing I would appreciate the information. Again the line began as a small black dot on the bottom of the sun and began rising upwards across the sun growwing in length to match the exact circumference of the sun as I viewed it. The line continued to grow until it reached the 1/2 way point of the sun and then began to shrink as it began its ascent to the top of the sun.

Where does heat go when it loses energy to entropy? I was once told that it is converted into other forms of energy that do not interact with the universe (as far as we know). Still, where does all the energy go, since it cannot be created or destroyed? -- Brasswatchman 20:15, September 8, 2005 (UTC)
Usually heat is the end result of entropy. Ordered energy like electricity might pass through a wire in an electric motor to produce mechanical energy, but some of that energy is lost to heat by interaction with the wire. A nuclear isotope ejects a subatomic particle and the particle bounces against air molecules and causes them to move more vigorously, that is heat. In the case of a hot object in a cool environment, the hot object tends to radiate heat away faster than the environment it is in. In that case the answer to your question is the heat goes to warm up the cool environment, so the heat is not lost, just spread out more evenly. So there is now a cooler object and a warmer environment, this is considered to be a less ordered situation, less order means greater entropy.
So the amount of energy in the universe remains constant - it just becomes spread out over a greater volume? -- Brasswatchman 22:00, September 8, 2005 (UTC)
Example:
2y = 18 2y/2 = 18/2 y = 9
or
2y = 18 y = 18/2 y = 9
In all my math classes they say to divide both sides by 2 and cancel the left one out, but I always just moved the 2 to the other side and don't have to cancel anything out. Is there something different between the two ways? -- pile0nades talk | contribs 20:38, 8 September 2005 (UTC)
Short cuts like this can cause problems when the math gets complex. Take this - I am not sophisticated enough to do exponents any other way so a^2 is the same as 'a' squared.
If the step noted is skipped it is harder to see that you are dividing by zero.

What is disodium phosphate and how is it used by the body?
Sodium phosphate is a salt and a buffer. In the body Na and phosphate ions exist in the extracellular and intracellular fluid in significant amounts. The amount of Na and H bound to the valence-3 PO4 anion varies with pH. The principal "use" of PO4 in the cells of the body is as a detachable moiety for high enery phosphorus compounds like ATP. Another principal use is as part of bone mineral in combination with calcium. There are pharmaceutical preparations of sodium phosphate as a phosphate source for intravenous or oral replacement of phosphate depletion (e.g., for treating people with diabetic ketoacidosis or X-linked hypophosphatemic rickets ), or as a buffer for those with certain types of impaired renal acidification. alteripse 11:24, 12 September 2005 (UTC)
Hi all,
I'm just writing a basic high school paper on nuclear fission, and in order to illustrate its efficiency over regular chemical reactions, I'm trying to find the amount of energy released by complete fission of 1g of uranium-236.
From Nuclear fission, a fission reaction produces about 200 MeV of energy, and according to google, this is equal to 3.20435292 × 10-11 J. So I tried the following equation, but the end result seems to be horribly wrong..
n(U-236) = m/M = 1/236 mol (Number of moles in a 1g sample of U-236) N(U-236) = n * N(A) = 1/236 * 6.02 * 1023 ≈ 2.55 * 1021 atoms (Number of atoms in that sample) E(U-236) = N(U-236) * 3.2 * 10-11 ≈ 81.6 GJ (gigajoules) (number of atoms multiplied by energy released by each fission in joules)
So am I using incorrect numbers to start with, is this procedure invalid, or does 1g of uranium really yield 81.6GJ? o_O

So I've discovered that my MP3 player plays files in alphabetical order, by file name. This is a good thing, since the player has no other way of ordering song selections, except a cumbersome playlist editor that I've given up on in frustration. So now if I want to play files in order, I can just copy them onto the player and then change their file names - to a, b, c, d, what have you.
Now, let's say that I wanted to write a program to save myself the trouble of changing each and every file name. I'm imagining something that has a window that I can drag-and-drop the songs I want into it, in order - then I can click a button and it'll write the files to the player, using alphabetical names.
The problem, of course, is that I haven't done any programming since my QBASIC days.
So, what's the simplest programming language, compatible with Windows XP, that will let me write this program I have in mind? Also, what would be the cheapest? Are there any other options that I have that might be able to do the trick?
Thanks. -- Brasswatchman 17:33, September 12, 2005 (UTC)

Can you list 4 items to look for when determining the reliability of a web site? What is flag searching? Thanks
I mean the reliability of information of a web site. For example, spelling. If they misspell a lot in that web site, so it's hard for us to belive its information. Do you know 3 more items? And what is flag searching? Thanks a lot.
Software used to update web sites is often user-hostile when it comes to doing spell checking. When you do e-mail, or word processing, it comes with spell checking, and it also comes with the ability of the end user to mess it up. The vast majority of web sites are created to look good from the perspective of the web browser version being used by the person who created the web site. Most web sites are hostile to people using other types of browsers, older computers, and older humans, whose eyesight has more trouble with color contrasts. Do you know how many people have disabilities, like blind, key stroke problems ... it is a huge percentage of the population that has some kind of disability, and most web sites are hostile to them.

Why is it important to back up files and data? What type of Operating System would be best for a school environment?
As for backup ... basically if it does not matter if you lose everything that is on your computer ... e-mail, files, documents, jokes, games, software, records of what you bought and paid for so you can prove you are a licensed user of something on the computer when you go to get help putting it back on after a crash, then you do not need a backup, or a computer either. But if what is on your computer is important to you, and you want to minimize the recovery time after a crash, melt down, virus, theft, natural disaster, etc. then you need to have various kinds of protection, such as surge protector anti-virus off-site backups, etc. AlMac| ;(talk) 07:31, 15 September 2005 (UTC)

What I did do was put a shortcut to your website on my desktop. The short cut did show up. But later at some point while I was on your site I think I may have inadventenly clicked on something. I can actual expand the square gray box and it will cover my entire desktop like it was an image I selected to be my desktop image.But I can click on it and it goes back to being a smaller image. I have gone to my control panel and looked at what is selected for my desktop image and it shows what I want to be there. It does not show the gray box as part of it. I have scrolled the different desktop images available and nothing shows up for a gray box. It actually acts like another desktop. I can put short cut icons on it!
At the very top of the gray box is a down arrow. If I "left click" the
options that come up are:

Customze my desktop

My husband is very knowledgable about computers and has no earthly idea what has happened. At some point in the past few days messing with this thing, something somewhere came up that did identify the image has having something to do with Wikipedia but I haven't been able to find where I saw that again.

I just saw a documentary on BBC about the 'big mistake' of Hawking, the information paradox. In this a formula was presented that was said to be so simple it had to be true, namely . It was presented as a big breakthrough of the greatest physiscist of our time (so a big one I'd say), but little else was said about it, so I thought I'd look it up here, but to no avail. I've looked at thermodynamics, because that's where the S comes from, and of course at Steven Hawking. Should I look elsewhere?
And isn't there (or else, shouldn't there be) an article with all physics formula grouped together (well, at least the most important ones)?

What is the role of a clinical project leader in phase 3 clinical trials for a new beta blocking agent?
Hi, I am a undergraduate student and currently carried out a project related to altimeter.The purpose of this project is to reduce the error of the altitude value due to the changing of the atmosphere pressure within a day. Since we know the pressure will be varied in a day regardless to the change of the altitude.This has cause the value of altitude given by altimeter become inaccuratue since altitude is calculated by pressure. The result is that,the altimeter can not give the actual value of the altitude at any location for a long duration.I would like to know is it possible to reduce or to calibrate the value of the altitude so that it can become more accurate?
Sure, with a barometer. The altitude at your location does not change, just the air pressure. All you need are some simultaneous barometer and altimeter readings at various air pressures at a constant altitude. Then you can calculate the magnitude of air pressure effect and compensate when you try the altimeter and barometer together at different altitudes. alteripse 15:00, 17 September 2005 (UTC)

Yes. y=0 sin(x) is a straight line through the origin. y=0 sin(x)+b is a straight line through b. Both of these can be considered degenerate sine functions.
If you give details of the experiment you did we may be able to help. Also, provided you did the experiment correctly, the results you got are the "truth". Rather than trying to fudge the answer to make it a straight line you may be better off doing a little more experimenting. For example look at the frequency o thr sine wave.

what kind of organic compound involved in fat formation contains carbonxyl groups?
Fat molecules are made from glycerol and 3 fatty acid molecules. Fatty acids are basically carboxylic acids with long carbon chains. It is the fatty acids that contain the carboxyl group.-- 82.44.216.80 10:24, 18 September 2005 (UTC)
Hello Sir, Could you please tell me how the prokaryotic organism, lets say E. Coli develop? I do not enough information on this organism developmant. Thanks.

Hey, true believers - so, I bought some used RAM for an old Gateway 700S desktop I have. Figure I can get a little life out of the new system this way. Only problem is, I seem to have purchased PC 800-[b]45[/b] RAM. My computer only seems interested in taking PC 800-[b]40[/b] RDRAM. Is there any way to force my computer to accept the new RAM in a way that does not compromise its functionality? Thanks. -- Brasswatchman 02:36, 19 September 2005 (UTC)
Answer: "If the RAM does not fit in the alloted slot, you will not be able to use it."
It does fit in the alloted slots. The problem is the Gateway 700s doesn't accept it. Even the technician at Gateway couldn't figure out why it wouldn't accept the 800-45. It usually takes an 800-40. I'm a different poster than the one above asking the same question, but I'm also trying to figure out what way for this to work.
I'm asking out of curiosity rather than dire need, since it's rarely an issue. Here's the thing:
My computer's fairly old by most people's standards, 200mb RAM, 133mhz, still running Win98. However, it serves me well, rarely giving me any problems, I can do pretty much everything I need to do with it and plenty of stuff I needn't: it gets lots of use and rarely complains.
What puzzles me is that occasionally I manually go through all the folders and files just to chuck out clutter and sometimes I've been very lazy about where I put my creations, so I do some tidying of files etc.
After a while of deleting and moving files my system slows to a crawl beyond anything that seemingly more intensive tasks (listening to audio files, streamed radio, playing a game with some graphical content, looking at flash animations etc) does.
It slows down horribly (moving one file from one folder to another can take 20 seconds, opening another folder in explore view takes 30 seconds). Why should that be? It's all solved with a reboot, as you may guess. -- bodnotbod 02:43, 19 September 2005 (UTC)

Hi, I was just wondering... How many characters (text-wise) could fit into a gigabyte? Cirrial 11:34, 19 September 2005 (UTC)
For someone from the western world, they are used to working with characters that occupy exactly one byte. "An egg" would use six bytes. Note that spaces and new lines are all characters (a new line is often two characters). In this case, a gigabyte would hold exactly as many characters as bytes in a gigabyte. But how big is a gigabyte? Either two to the power 30 or ten to the power 9, respectively 1073741824 or 1000000000. If we say "about a thousand million" we won't be far wrong.
So, for many people in the western world, about a thousand million characters. But what about people outside the western world? In Japan, they often use a system where a character fits in two bytes. So in this system, the Japanese could get about 500 million characters.
Many people, all over the world, use a system called Unicode. There is more than one kind of Unicode. If they use a kind called UCS-2, every character is 2 bytes. That means that if you use UCS-2, you get about 500 million characters, no matter what language is used. Another kind of Unicode is called UTF-8. In this, non-accented English letters use one byte, european accents use two bytes, and Japanese uses three bytes. So it really depends now, somewhere between 300 million and 1000 million characters.
This all assumes a file contains nothing but text. In Windows terms, a TXT file. Other types of file may have overheads so there are less characters than you would get in TXT, or compression, so there are more characters. DOC files have overhead, so it is less characters (of the actual text). PDF files have overhead and compression and may well get more characters than a TXT in some cases (not others).
Clear now? Notinasnaid 11:46, 19 September 2005 (UTC)

How many pieces of 8 1/2 x 11 or A4 paper would you need to conserve to save a single tree?
On the other hand, as noted by jpgordon, we can still ask how many sheets of paper can be made from one tree. Based on the link provided by Nunh-huh, we can get 89,870 "sheets of letterhead bond paper" from a cord of wood, and 10 – 15 cords from an acre of forest. Thus: 898,700 – 1,348,050 sheets from an acre. Now all we have to do is figure out how many trees are typically in an acre. Random Google searches produce numbers like 25, 50, or 100. So let's say 25 – 100 trees per acre. Dividing, we get 8,987 – 53,922 sheets per tree. In summary, it varies, but 10,000 – 50,000 is probably a decent estimate.

The particle theory of light states that the main particle in light is a photon and it has been proven that photons of light must have a mass (even if extremely low) because they cannot escape a black hole. If, theoretically, you shone light directly into a blackhole this would certainly speed up the light photons as by Newton's law; acceleration = mass x force. Therefore how is it that the speed of light is thought of as a constant?
Furthermore in the special theory of relativity as you get close to the speed of light, time itself slows down until it comes to a stand still at the speed of light. If light was to go faster than the speed of light (assuming the 'speed of light' is the speed of light throughout space) then wouldn't that mean the light entering a blackhole was going back in time?
By the way, there is an interesting and somewhat related issue here that no one has brought up. Yes, the speed of light varies depending on the medium it is passing through. When we say "nothing can go faster than the speed of light" we really mean "the speed of light in a vacuum". That means that if we are not in a vacuum, then it is theoretically possible for an object to go faster than light.
This has interesting implications. What happens when an object in the air goes faster than sound? Answer: a shockwave, whose sound is often called a "sonic boom". An object traveling faster than the speed of light in some medium can produce similar electromagnetic shockwaves. These go by the name " Cherenkov radiation". For more information, refer to that article.

What do doctors add in the medicine that contains antibodies in a syringe?
I might have misunderstood your question... but if you mean excipients (agents that are added to improve stability of the active ingredient or to maintain it in solution) then you can find quite a lot of information on the electronic Medicines compendium if you know the name of the vaccine. The website is http://emc.medicines.org.uk and once you've typed in the name of the vaccine, choose the link with the letters SPC (which stand for Summary of Product Characteristics) next to it, and browse the excipients section (I think it is always section 6.1). This works for UK medicines, I don't know what other databases there are, but Google might have the answer. Hope that helps, Jo Brodie, 16:49 BST, August 30, 2005.
This is a peculiar question and I suspect represents a misunderstanding or a non-Western practice. It is extremely rare for American or western European doctors to give injections of antibodies in a syringe. Antibodies in the form of gamma globulin are given by iv infusion for many problems but this doesn't involve a syringe. I cannot off the top of my head think of any examples except old fashioned passive immunity treatments for rabies, tetanus, and snakebite antivenin. There are a number of newer monoclonal antibodies used as treatments for specific uncommon conditions, but most of these are still experimental research protocols and most are given by infusion rather than injection. There were some quack cancer treatments involving injections in the past which claimed to induce a patient to make antibodies against the tumor, but these were pretty uncommon.

Luminous toxin is a descriptive term for an actual poison.'' — Technical Adviser, Edward F.

Explain why in a group of 35 children at a school, a randomly selected individual has a high probability of being the oldest son or daughter in his or her family.
--anonym
Presumably this is a math assignment. If the average number of children per family are less than 2 (as is true in most of the western world), any randomly chosen child is more likely to be an eldest than a non-eldest.
Average children per family (CperF) can be expressed as N1+N2+N3+N4+N5+N6...+N20 divided by the NF, where N1 is total number of eldest children, N2 is total number of second children, N3 is total number of third children, etc, and NF is the total number of families. There is a value of CperF below which more than half of any group of children are eldest (N1). Is this what you are supposed to compute? It would be somewhat above 2 because preschoolers (age under 5 years) would be selectively excluded from your classroom sample.
Unless King Herod or the Tenth Plague of Egypt has visited the community lately, there will always be more eldest children than second, more second children than third, etc (i.e., N1>N2>N3...N20), so that even in a society in which there are on average many children per family (high CperF), any randomly chosen child is more likely to be an eldest than a second, third, fourth, etc. alteripse 11:16, 31 August 2005 (UTC)

As someone who has spent entirely too much money in lifetime paying Dentist bills, and now 100% false teeth, it seems to me the battle was to save what was left of eroded teeth until I was willing to part with the last of them. In children there is something called wisdom teeth, in which something grows, comes out, then is replaced with another, but in my adult experience, once you got a damaged tooth, or a cavety, the dentist can patch it up, but there is no "natural" cure. AlMac|(talk) 07:18, 30 August 2005 (UTC) I'm not sure what you mean about the wisdom teeth? --Phroziac (talk) 16:58, September 3, 2005 (UTC) Children will exchange their milk teeth, but after that your teeth won't grow anymore. I speak from experience as two people in my family had broken front teeth. The dentist patched it up with fake teeth or fake partial teeth, but once damaged, adult teeth can not recover. In fact, once you've exchanged your teeth as a kid, your new teeth won't grow anymore. They're already adult size. - Mgm|(talk) 08:37, August 30, 2005 (UTC) Humans only get two sets of teeth - their milk teeth and the adult set, though the wisdom teeth at the back may not appear until you're in your twenties and (in my case) have to come out straight away. If you damage your adult teeth, that's it, you're stuck weith them - they don't grow any more. -- Arwel 12:24, 31 August 2005 (UTC) Which I can, unfortunatly, confirm from my own exprerience.

Medical Information Edit
What do doctors add in the medicine that contains antibodies in a syringe?
I might have misunderstood your question... but if you mean excipients (agents that are added to improve stability of the active ingredient or to maintain it in solution) then you can find quite a lot of information on the electronic Medicines compendium if you know the name of the vaccine. The website is http://emc.medicines.org.uk and once you've typed in the name of the vaccine, choose the link with the letters SPC (which stand for Summary of Product Characteristics) next to it, and browse the excipients section (I think it is always section 6.1). This works for UK medicines, I don't know what other databases there are, but Google might have the answer. Hope that helps, Jo Brodie, 16:49 BST, August 30, 2005.
This is a peculiar question and I suspect represents a misunderstanding or a non-Western practice. It is extremely rare for American or western European doctors to give injections of antibodies in a syringe. Antibodies in the form of gamma globulin are given by iv infusion for many problems but this doesn't involve a syringe. I cannot off the top of my head think of any examples except old fashioned passive immunity treatments for rabies, tetanus, and snakebite antivenin. There are a number of newer monoclonal antibodies used as treatments for specific uncommon conditions, but most of these are still experimental research protocols and most are given by infusion rather than injection. There were some quack cancer treatments involving injections in the past which claimed to induce a patient to make antibodies against the tumor, but these were pretty uncommon.

The Earth is pretty rough at that scale - you have mountains, seas, that sort of thing - which are very inhomogenous; it'd be like dealing with a lot of weird mascons. (Consider the gravitational effects of "ring next to a mountain" vs. "ring over central Pacific). It'd probably "crash to the ground" somewhere along the length - or, indeed, buckle under its own weight and do so all over the place. Shimgray 19:55, 30 August 2005 (UTC) It wouldn't be very stable unless you spun it, but you could make it a geosynchronous orbit. You might want to look at Ringworld and Dyson sphere. Bovlb 19:59:37, 2005-08-30 (UTC) At geosynch you might manage stable, but not at a kilometer high - local mass differences are just too significant, then.

AlMac|(talk) 06:08, 31 August 2005 (UTC) The plan for that is to be above geosynchronous orbit (much much more than 1 km above the surface). Technically it would work at geosynchronous orbit, but the designers want the elevator structure to be under some tension. The ring structure would "hover" at geosynchronous orbit, except that our geoid isn't perfect and we've dumped lots of satellites up there, so I don't think it'd be particularly stable, but — as mentioned above — spinning it up would help. — Laura Scudder | Talk 15:49, 31 August 2005 (UTC) I believe the general concept is to counterweight an elevator so that the center of gravity is at the geosynch point.

White phosphorous, specifically, glows and is a systemic poison, although mostly known for bone damage. This was probably close enough for the purposes of a sensational movie script. However, having several days of relative health before dying (despite the best medical intervention) is possibly more charactistic of overdose from paracetamol or deadly Amanita mushrooms, both of which cause liver failure that results in death after an initial recovery 131.172.99.15 (talk) 12:44, 23 December 2008 (UTC)snaxalotl Without a reliable citation, phosphorous or one of its compounds is just a guess.

Power and torque output (of WRC cars)

How can the engine develop such a high amount of torque considering that the power output is not that high? Isn't there an inconsistency between the figures? Am I just miscalculating or how is this possible? Thanks, --Ozkaplan
According to the article on torque, if P P is power in kilowatts, T T is torque in Newton metres, and R = rotational speed in revolutions per minute, if you manipulate the constants: P = T × R × 2 π 60000 {\displaystyle P={\frac {T\times R\times 2\pi }{60000}}} If you plug in T = 635 and R = 4000 into that I get approximately 266 kilowatts, which is about 357 horsepower. Considerably over the limit, still. As to how it's done, let's just say that creative interpretations of physics, mathematics, and indeed logic pertaining to rulebooks have been a stock in trade of automobile racing for a very long time. In the 1980's, the maximum level of turbo boost in Formula One was supposed to be restricted by the use of a standard popoff valve, which opens up to bleed off pressurised air if the pressure gets too high. Teams apparently got around this by fitting huge turbos to their qualifying motors which pumped so much air the popoff valve couldn't get rid of it all...--Robert Merkel 12:18, 31 August 2005 (UTC) computers Edit

Most statistics books seem to be written by people who lack basic descriptive skills or have yet to have agood grasp of English writing. Here we see a statistic textbook explaining cummulative frequency, a complex name for an extremely brain-dead operation, and explains it with great complexity:
"A cummulative frequency distribution can be created from a frequency distribution by adding an additional column called "Cummulative Frequency." For each score value the cummulative frequency for that score value is the frequency up to and including the frequency for that value."
Is there any books, or other sources anyone can recommend to me that will not try to complicate this very simple subject?

Hi there-- recently I have been finding out about gravity and a question keeps itching me. If you were to drain half of the magma from the earths core would the remaining liquid rearrange itself into a perfect sphere centred around the point at which gravity for this planet is generated?
In case that was slightly confusing what i mean to ask is that gravity is a single point in the exact centre of our planet so if there was just an open void around that point and something was placed on that point would it just float exactly still as forces are acting equally uopn it in every directon?
Thanks for the answer but it leads me to another question. If every part of the earth produces a gravitational pull and these minute pulls combine to form what appears to be one force known as gravity why is it that we are not pulled slightly towards huge clusters of particles like say a mountian and also why is it that all of these forces seem to pull towards one point in the centre of the earth?
Oh and your comment about getting closer to one side of the sphere and the force growing stronger but the lack of particles meaning they even each other out. What is that supposed to mean? These particles that are fewer as you move closer to one side, are they supposed to be air particles because thats the only thing i can imagine moving through as easily as you say. And even each other out!!?? If the forces evened each other out wouldn't you be stuck in your position unable to move unless you can produce a force strong enough to move in a direction?
One more thing, if 'particles' of whatever it is are responsible for gravity then is a black hole just an unspeakable number of them clustered together?

Is there any simple (free) way of transforming a word document to a pdf? I tried converting to OpenOffice, but their pdf converter makes the document ugly. Why doesn't Word have its own converter?
Thanks! --Alice
Hi all, thanks for your replies.
I tried Pidgeot's suggestion and it seemed to work well. However, it changes the formatting o my document. I've got a 40+ page paper, with chapter headings at the tops of pages and References at the end. There appear to be a different number of lines per page in the pdf, which makes my headings appear in varying places down the page, and the references after 1 1/2 blank pages. How can I get it so that the formatting is the same as in my word document (and yes, I'll learn latex for the next paper!).

Alice: If you are working on, or have access to, an Apple Macintosh running Mac OS X, and which also has a copy of Word (perhaps your local library or uny computer lab?), it's easy: Open the file up with Word on the Mac, select "Print" from the "File" menu, then click the "Save as PDF" button.

I'd go for taste if it wasn't for the potentially deadly results. If you disolve it in water and it the water can now transfer electricity it's a salt. If you smell cloride it's a cloride salt. You can then add other water solutable salts to test whcih to ions the salt was composed of (look in the chapter Salts in your chemistry book for the exact procedure). -- R.Koot 03:55, 2 September 2005 (UTC)

Also flame test and borax bead test. These will help identify the substance, if only to show what it isn't, since some substances do not give helpful results. Melting point is another useful tool, as well as density.
Hi, I know this might not be technical enough to warrant your attention but do you happen to know the exact speed of sound in MPH, KPH and Knots? I know its around 750MPH but i need to be sure in order for my calculations to be correct. Ryan
In that case can you tell me which sequence of variables they use to determine the top speed of planes ie. If a company states it's plane can go Mach 2 then which speed are they referring to as it could be anywhere between 1200mph and 1400mph?
Just to complicate things, note that a plane (a jet, as prop plane are always subsonic, I think) will go faster in rarefied air, because of reduced friction, but sound will tavel slower in that medium. There is a law of diminshing returns here, as rarefied air will provide less oxygen to the jet engine and it will produce less power.
Hi,
I recently read an article on a similar site that stated; if you were on a train travelling at 1000mph (and the ride was so smooth you couldn't notice) and you fired a bullet off the front of the train (in the exact direction it was travelling) then the bullet would be travelling at 2000mph relative to a stationary point on the ground and at 1000mph realtive to your position (moving at 1000mph). This I can believe, but it also states that if you fired a bullet under the same circumstances off the back of the train (this is all theory, I'm not taking into account aerodynamics or anthing) that the bullet would be travelling at 2000mph relative to your position on the moving train but it would be travelling at 0mph in relation to a stationary point on the ground. This suggests that the bullet would float in that air on then just fall to the ground. Is that correct because it seems very unlikely?
Thank you to R.Koot and StratOnLSD (interesting name) for those answers, and to Notinasnaid; I believe if you read my question you would understand I was disregarding any other forces, variables and factors not covered in my question and if technicality is your specialty (which it appears to be) then you shouldn't have answered a question about a train moving at 1000mph.

I got stumped working on the Elbow macaroni article. They make macaroni by extruding dough through a circular die with a pin blocking the center of the circle. I see a number of references that say that a "groove" in the pin causes the pasta to curve as it is extruded. How? What does this groove look like? Why doesn't it form a ridge or valley on the finished product? Bunchofgrapes 17:11, 2 September 2005 (UTC)
It has to do with relative rates of extrusion. Pasta machines work by forcing pasta dough through a die, which simplistically speaking is just a negative silhouette of the desired shape. But if more dough is forced through one part of the die than another part, the extrusion there will happen faster, and the extruded pasta will curl.
A picture will make this much clearer.
Here is the front view of an elbow macaroni die:
This is about 30cm in diameter, and as you can see it extrudes 5 tubes of pasta at once.
But now let's look at the back:
The ridges you see divide the total output of the pasta machine
(that is, the stream of pasta dough which this die is the target of)
into ten "capture regions".
(There's a rather nice analogy here to
watershed.)
Two regions flow into each extruded macaroni tube,
but significantly, one of them (the outer one) is considerably larger than the other.
Therefore, the outer edge of each tube will extrude faster than the inner, and each one will therefore curl inwards.
I haven't seen one, but I presume that the die for curly-edge lasagne consists of the long straight slit you would expect, but with some extra "capture region" at each end of the slit (corresponding to each edge of the lasagne ribbon). In this case, the extra dough volume is too localized to cause a curl, but it has to go somewhere. The edges end up being "too long" for the main body of the ribbon, so the edges end up rippling to consume the extra material.

A slot machine has three wheels: Each wheel has 11 positions – a bar and the digits 0, 1, 2,…, 9. When the handle is pulled, the three wheels spin independently before coming to rest. Find the probability that the wheels stop on at least one bar.
I have two answers. I think the first one is right, but I do not understand why the second one might be wrong.
P(E1) = , where I subtract the probability of getting no bar three consecutive times (10/11)3 from 1.
P(E2)= , where I add the probability of getting one bar, two bars, and three bars.
Can you explain this discrepancy? Why do these two answers not conform to each other?
--anonym
To expand on Y0u's answer. The probability of getting one bar is
i.e. the probabliity of a bar on the 1st multiplied by a not bar on the other two multiplied by three (because the bar could be on any of the three not just the first one).
Likewise the probability of two bars is

Nope. For P(4 games) you need to have one of the two teams win all four games in a row. (There is no other way it can happen). Call the teams A and B. So I reckon (and I'd like people to check my reasoning please) that
Where means the probability that side A wins game 1 and so on.

To whom this may concern,
I am typing this question to you hopping that i will be takin seriously. I have taken a course in collage on chemistry, and have started to take an other course in solar systems. When i sat down i took a look at a cell make up and looked at the whole solar system. if you look at them they do have a similar look to them. Now the only difference that i can make out is that the levels of electrons on the solar system does not consist of the same law.... or does it. when we look at a cell through a microscope we shed light to the whole area of the cell. Now if we where to take that light and project it on an angle or completely to it's side would the electrons cast a shadow to the other electrons and unable us to see the other electrons needed make the cell function to what our law says. Now if we think of the Solar System the sun sheds light on an angle causing a cone shaped shadow hiding the "other planets/electrons". Also as we all know all means of life needs wheather it be light, water, oxygen, other living things... Thinking of electrons what if they needed light to be at its full ability to function so the the cell was able to split? if so what if it needed that light for a certain amount of time to make it visble to the eye weather it beeing seen through a microscope looking at a cell or lookin thruogh a telescope looking out at space. With all this my question is are us humans on a cell called the solar system?
P.S. If you could kindly help me clear my mind it would be greatly appreatiated.

Hey, everyone,
So, once again, abusing this source of Internet knowledge in lieu of a technical support service - I have a desktop and a notebook that I'd like to network together via a crossover cable (modified Ethernet cable - everyone know what I'm talking about?). The trick is, my desktop has an Ethernet cable plugged into it most times, which connects it to the Internet via my college network. In order to connect to the college network, there are all sorts of configurations I have to place on the connection. So many, in fact, that if I switch the Ethernet cable for the croosover cable to my laptop, I have to reconfigure the connection back to its original settings, which takes forever.
Here's my question: is it possible for me to set up a network between my laptop and my desktop, which ONLY comes into play when I connect them via the crossover cable? And is there any easy way to go back to the settings the desktop needs to connect to the college network? Both computers, by the way, use Windows XP.
Well, I hope at least some of the above is understandable. If any clarification is required, all you have to do is ask.

Hey, everyone,
I'm a science fiction writer trying to cobble together a concept. Any scientists out there, would you tell me if there is anything extraordinarily stupid about what I'm about to suggest? - Radiation is, when you get right down to it, just a group of rogue particles created or emitted by a substance undergoing decay - either accelerated, in the case of fission, or slow, as in standard radioactive decay. So since radiation is a particle, it should be technically possible to filter out radiation on an atomic level through nanotechnology. I'm thinking of what basically looks like the quantum equivalent of the Strategic Defense Initiative - something that spits out a particle to deflect or destroy the radioactive particle. Or maybe a better idea would be a quantum-sized "filter" that lets in some particles but not others; basically acting as a net that lets larger particles through but grabs the radioactive particles. -- Brasswatchman 23:15, September 6, 2005 (UTC) So, where am I wrong? Thanks. -- Brasswatchman 21:14, September 5, 2005 (UTC)
How are you going to destroy the particle? You could annihilate it with it's antiparticle but the energy would still be there in the form of gamma rays. You can stop gamma rays with matter. A bloody great lump of lead should do the trick - bit that's probably too crude for you.
Some sort of net? The thing about radiation is that it is ionising Maybe your net could be transparent when neutral but turns opaque when it's ionised. Theresa Knott (a tenth stroke) 22:04, 5 September 2005 (UTC)
Well: (1) not all radiation is particulate (ie, massive particles); (2) even the "biggest" (most massive) particle radiation—the heavy cosmic rays—are only atomic nuclei, whereas nanotechnology is at the scale of cells or big molecules; (3) SDI presupposed a method to detect and track ICBMs from launch, but you have nothing analogous to that at the nuclear level; (4) even if, somehow, you managed to annihilate a cosmic ray, you now have gamma radiation carrying the combined energy of the original particle and your magic bullet; (5) it is misguided to say that particle radiation is composed of "radioactive" particles, since most of it is perfectly stable atomic nuclei or free electrons; (6) "quantum-sized" is not a definable term. I hope this helps. Sharkford 22:06, 5 September 2005 (UTC)
Just remember that sometimes sci-fi is more enjoyable (even for scientists) when it leaves how things work to the imagination rather than trying to cobble together an explanation from jargon.

Is Banana peel actually especially slippery?
Yes. As the outside of a banana peel (the more yellow side) is actually quite sticky (try rubbing your hand across it - there's a lot of friction there), and the whiter inside has (when still moist) a very low coefficient of
friction, when you put your foot on the peel, the friction of the yellow, outer side ensures your foot will stay on the peel, while the slippery inside will ensure you slide across the floor, and usually fall over.
However, for this to happen, three things need to occur: 1) The peel must have the slippery (inside) side on the floor, and the yellow outer peel facing upwards. 2) The floor the peel is on must be hard and relatively smooth (ie, a polished or tiled floor). 3) The peel must still be moist (ie, not been there for a while.
So yes. A banana peel is especially slippery. Proto t c 13:08, 7 September 2005 (UTC)

Note that both of these elements have no stable isotopes even though the ones next to them do.
Also note that if the Rare Earth (Lanthanides) are extended in place of the third period of the transition elements, Promethium appears right under Technetium. Also note that both atomic numbers are prime numbers whereas Manganese is not. Some discussion of if this is just coincidence or if there is a story to tell there would be interesting to me.
I dont' know what you mean by 'proper' A 'proper' arrangement of the elements is just as it is now, with the Rare Earths in their own group. I am suggesting an 'improper' arrangement, but one which is not random check this out.

Hello,
My name is Adam Rogers and I live in Conway, AR. On a roadtrip yesterday I noticed a horizontal black line which spanned the distance of the sun and no other parts of the sky. There were no clouds and no jet trails, even had there been they would not have blocked the sunlight in such a fashion. The occurence I observed lastted about 15 minutes and the black line followed the size of the sun from top to bottom as the line rose upwards across the sun. If anyone has seen a black horizontal line on the sun before or has any explanation as to why my eyes would have perceived such a thing I would appreciate the information. Again the line began as a small black dot on the bottom of the sun and began rising upwards across the sun growwing in length to match the exact circumference of the sun as I viewed it. The line continued to grow until it reached the 1/2 way point of the sun and then began to shrink as it began its ascent to the top of the sun.

Where does heat go when it loses energy to entropy? I was once told that it is converted into other forms of energy that do not interact with the universe (as far as we know). Still, where does all the energy go, since it cannot be created or destroyed? -- Brasswatchman 20:15, September 8, 2005 (UTC)
Usually heat is the end result of entropy. Ordered energy like electricity might pass through a wire in an electric motor to produce mechanical energy, but some of that energy is lost to heat by interaction with the wire. A nuclear isotope ejects a subatomic particle and the particle bounces against air molecules and causes them to move more vigorously, that is heat. In the case of a hot object in a cool environment, the hot object tends to radiate heat away faster than the environment it is in. In that case the answer to your question is the heat goes to warm up the cool environment, so the heat is not lost, just spread out more evenly. So there is now a cooler object and a warmer environment, this is considered to be a less ordered situation, less order means greater entropy.
So the amount of energy in the universe remains constant - it just becomes spread out over a greater volume? -- Brasswatchman 22:00, September 8, 2005 (UTC)

Short cuts like this can cause problems when the math gets complex. Take this - I am not sophisticated enough to do exponents any other way so a^2 is the same as 'a' squared.
If the step noted is skipped it is harder to see that you are dividing by zero.

What is disodium phosphate and how is it used by the body?
Sodium phosphate is a salt and a buffer. In the body Na and phosphate ions exist in the extracellular and intracellular fluid in significant amounts. The amount of Na and H bound to the valence-3 PO4 anion varies with pH. The principal "use" of PO4 in the cells of the body is as a detachable moiety for high enery phosphorus compounds like ATP. Another principal use is as part of bone mineral in combination with calcium. There are pharmaceutical preparations of sodium phosphate as a phosphate source for intravenous or oral replacement of phosphate depletion (e.g., for treating people with diabetic ketoacidosis or X-linked hypophosphatemic rickets ), or as a buffer for those with certain types of impaired renal acidification. alteripse 11:24, 12 September 2005 (UTC)
Hi all,
I'm just writing a basic high school paper on nuclear fission, and in order to illustrate its efficiency over regular chemical reactions, I'm trying to find the amount of energy released by complete fission of 1g of uranium-236.
From Nuclear fission, a fission reaction produces about 200 MeV of energy, and according to google, this is equal to 3.20435292 × 10-11 J. So I tried the following equation, but the end result seems to be horribly wrong..
n(U-236) = m/M = 1/236 mol (Number of moles in a 1g sample of U-236) N(U-236) = n * N(A) = 1/236 * 6.02 * 1023 ≈ 2.55 * 1021 atoms (Number of atoms in that sample) E(U-236) = N(U-236) * 3.2 * 10-11 ≈ 81.6 GJ (gigajoules) (number of atoms multiplied by energy released by each fission in joules)
So am I using incorrect numbers to start with, is this procedure invalid, or does 1g of uranium really yield 81.6GJ? o_O

So I've discovered that my MP3 player plays files in alphabetical order, by file name. This is a good thing, since the player has no other way of ordering song selections, except a cumbersome playlist editor that I've given up on in frustration. So now if I want to play files in order, I can just copy them onto the player and then change their file names - to a, b, c, d, what have you.
Now, let's say that I wanted to write a program to save myself the trouble of changing each and every file name. I'm imagining something that has a window that I can drag-and-drop the songs I want into it, in order - then I can click a button and it'll write the files to the player, using alphabetical names.
The problem, of course, is that I haven't done any programming since my QBASIC days.
So, what's the simplest programming language, compatible with Windows XP, that will let me write this program I have in mind? Also, what would be the cheapest? Are there any other options that I have that might be able to do the trick?

Software used to update web sites is often user-hostile when it comes to doing spell checking. When you do e-mail, or word processing, it comes with spell checking, and it also comes with the ability of the end user to mess it up. The vast majority of web sites are created to look good from the perspective of the web browser version being used by the person who created the web site. Most web sites are hostile to people using other types of browsers, older computers, and older humans, whose eyesight has more trouble with color contrasts. Do you know how many people have disabilities, like blind, key stroke problems ... it is a huge percentage of the population that has some kind of disability, and most web sites are hostile to them.

But if what is on your computer is important to you, and you want to minimize the recovery time after a crash, melt down, virus, theft, natural disaster, etc. then you need to have various kinds of protection, such as surge protector anti-virus off-site backups, etc. AlMac| ;(talk) 07:31, 15 September 2005 (UTC)

I can actual expand the square gray box and it will cover my entire desktop like it was an image I selected to be my desktop image.But I can click on it and it goes back to being a smaller image. I have gone to my control panel and looked at what is selected for my desktop image and it shows what I want to be there. It does not show the gray box as part of it. I have scrolled the different desktop images available and nothing shows up for a gray box. It actually acts like another desktop. I can put short cut icons on it!

I've looked at thermodynamics, because that's where the S comes from, and of course at Steven Hawking. Should I look elsewhere?

What is the role of a clinical project leader in phase 3 clinical trials for a new beta blocking agent?
Hi, I am a undergraduate student and currently carried out a project related to altimeter.The purpose of this project is to reduce the error of the altitude value due to the changing of the atmosphere pressure within a day. Since we know the pressure will be varied in a day regardless to the change of the altitude.This has cause the value of altitude given by altimeter become inaccuratue since altitude is calculated by pressure. The result is that,the altimeter can not give the actual value of the altitude at any location for a long duration.I would like to know is it possible to reduce or to calibrate the value of the altitude so that it can become more accurate?
Sure, with a barometer. The altitude at your location does not change, just the air pressure. All you need are some simultaneous barometer and altimeter readings at various air pressures at a constant altitude. Then you can calculate the magnitude of air pressure effect and compensate when you try the altimeter and barometer together at different altitudes. alteripse 15:00, 17 September 2005 (UTC)

Yes. y=0 sin(x) is a straight line through the origin. y=0 sin(x)+b is a straight line through b. Both of these can be considered degenerate sine functions.
If you give details of the experiment you did we may be able to help. Also, provided you did the experiment correctly, the results you got are the "truth". Rather than trying to fudge the answer to make it a straight line you may be better off doing a little more experimenting. For example look at the frequency o thr sine wave.

Only problem is, I seem to have purchased PC 800-[b]45[/b] RAM. My computer only seems interested in taking PC 800-[b]40[/b] RDRAM. Is there any way to force my computer to accept the new RAM in a way that does not compromise its functionality? Thanks. -- Brasswatchman 02:36, 19 September 2005 (UTC)
Answer: "If the RAM does not fit in the alloted slot, you will not be able to use it."
It does fit in the alloted slots. The problem is the Gateway 700s doesn't accept it. Even the technician at Gateway couldn't figure out why it wouldn't accept the 800-45. It usually takes an 800-40. I'm a different poster than the one above asking the same question, but I'm also trying to figure out what way for this to work.
I'm asking out of curiosity rather than dire need, since it's rarely an issue. Here's the thing:
My computer's fairly old by most people's standards, 200mb RAM, 133mhz, still running Win98. However, it serves me well, rarely giving me any problems, I can do pretty much everything I need to do with it and plenty of stuff I needn't: it gets lots of use and rarely complains.
What puzzles me is that occasionally I manually go through all the folders and files just to chuck out clutter and sometimes I've been very lazy about where I put my creations, so I do some tidying of files etc.
After a while of deleting and moving files my system slows to a crawl beyond anything that seemingly more intensive tasks (listening to audio files, streamed radio, playing a game with some graphical content, looking at flash animations etc) does.
It slows down horribly (moving one file from one folder to another can take 20 seconds, opening another folder in explore view takes 30 seconds). Why should that be? It's all solved with a reboot, as you may guess. -- bodnotbod 02:43, 19 September 2005 (UTC)

Hi, I was just wondering... How many characters (text-wise) could fit into a gigabyte? Cirrial 11:34, 19 September 2005 (UTC)
For someone from the western world, they are used to working with characters that occupy exactly one byte. "An egg" would use six bytes. Note that spaces and new lines are all characters (a new line is often two characters). In this case, a gigabyte would hold exactly as many characters as bytes in a gigabyte. But how big is a gigabyte? Either two to the power 30 or ten to the power 9, respectively 1073741824 or 1000000000. If we say "about a thousand million" we won't be far wrong.
So, for many people in the western world, about a thousand million characters. But what about people outside the western world? In Japan, they often use a system where a character fits in two bytes. So in this system, the Japanese could get about 500 million characters.
Many people, all over the world, use a system called Unicode. There is more than one kind of Unicode. If they use a kind called UCS-2, every character is 2 bytes. That means that if you use UCS-2, you get about 500 million characters, no matter what language is used. Another kind of Unicode is called UTF-8. In this, non-accented English letters use one byte, european accents use two bytes, and Japanese uses three bytes. So it really depends now, somewhere between 300 million and 1000 million characters.
This all assumes a file contains nothing but text. In Windows terms, a TXT file. Other types of file may have overheads so there are less characters than you would get in TXT, or compression, so there are more characters. DOC files have overhead, so it is less characters (of the actual text). PDF files have overhead and compression and may well get more characters than a TXT in some cases (not others).
Clear now? Notinasnaid 11:46, 19 September 2005 (UTC)

How many pieces of 8 1/2 x 11 or A4 paper would you need to conserve to save a single tree?
On the other hand, as noted by jpgordon, we can still ask how many sheets of paper can be made from one tree. Based on the link provided by Nunh-huh, we can get 89,870 "sheets of letterhead bond paper" from a cord of wood, and 10 – 15 cords from an acre of forest. Thus: 898,700 – 1,348,050 sheets from an acre. Now all we have to do is figure out how many trees are typically in an acre. Random Google searches produce numbers like 25, 50, or 100. So let's say 25 – 100 trees per acre. Dividing, we get 8,987 – 53,922 sheets per tree. In summary, it varies, but 10,000 – 50,000 is probably a decent estimate.

General Idea That I have is that one simply recourses north until one falls off the grid.Recursion automatically takes care of backtracking to a legal grid point & then recursing to the east.

The particle theory of light states that the main particle in light is a photon and it has been proven that photons of light must have a mass (even if extremely low) because they cannot escape a black hole. If, theoretically, you shone light directly into a blackhole this would certainly speed up the light photons as by Newton's law; acceleration = mass x force. Therefore how is it that the speed of light is thought of as a constant?
Furthermore in the special theory of relativity as you get close to the speed of light, time itself slows down until it comes to a stand still at the speed of light. If light was to go faster than the speed of light (assuming the 'speed of light' is the speed of light throughout space) then wouldn't that mean the light entering a blackhole was going back in time?
By the way, there is an interesting and somewhat related issue here that no one has brought up. Yes, the speed of light varies depending on the medium it is passing through. When we say "nothing can go faster than the speed of light" we really mean "the speed of light in a vacuum". That means that if we are not in a vacuum, then it is theoretically possible for an object to go faster than light.
This has interesting implications. What happens when an object in the air goes faster than sound? Answer: a shockwave, whose sound is often called a "sonic boom". An object traveling faster than the speed of light in some medium can produce similar electromagnetic shockwaves. These go by the name " Cherenkov radiation". For more information, refer to that article.
