i need to know the answer to n=4
Your question isn't clear. First off, what is an " electron hotel" ? StuRat 15:49, 8 January 2007 (UTC)
The Lambertian reflectance article says that it is used as a model for diffuse reflection, and for most of its mathematics links to the Lambert's cosine law article which says that blackbodies obey it (the Stefan-Boltzmann law article corroborates this). However, while diffuse reflection provides equal intensity in every direction, and I was under the impression that black-body radiation carried that property (see for instance the end of the linked section: "the radiation is the same in all directions"), the cosine law does not appear to do so. What gives between these three concepts, each of which is attached to the other two in inconsistent ways? -- Tardis 02:21, 8 January 2007 (UTC)
What cities offer on street parking meters and off street parking spaces which are fitted with electric vehicle recharge stations (including area or spaces reserved for electric bikes under 750 watts) and ask a lower price for recharging than the equivalent energy cost of gasoline? -- Barringa 21:13, 7 January 2007 (UTC)
Is meme a scientific concept? How does one find out? Is there a procedure to determine if a concept is scientific or not? 202.168.50.40 04:21, 8 January 2007 (UTC)
I would say that gene is much more 'scientific' than meme; the former has a huge number of ancillary terms surrounding it, while meme does not. Vranak
People such as Ed Wilson have explained the biological basis for memes. The main problem is that while the physical basis of genes has been very well defined by molecular biologists the neural networks that allow memes to exist are still being investigated....it is a much more technically difficult problem. Secondarily, the idea that our genes have influences on our mental lives it not currently a popular idea within the soft sciences. Anyone who studies the links between genes, memes and culture is attacked by thought police who are not interested in the science. -- JWSchmidt 18:24, 8 January 2007 (UTC)
What would the atomospheric pressure be at an elavation euqual to the bottom of the Atlantic seafloor, but uncovered by water? In other words, if there was an open place on earth where the elevation was that low, would the pressure still be significantly different than sea level?
Klatue 06:23, 8 January 2007 (UTC)Klatue
(I fixed the spelling of the question title.)
This table is extracted from the 1986 edition of the " Rubber bible". The left-hand column is depth below sea level in meters, the right hand air pressure in millibars.
0 1013.25 500 1074.7 1000 1139.3 1500 1206.9 2000 1277.8 2500 1352.0 3000 1429.7 3500 1510.9 4000 1595.9 4500 1684.8 5000 1777.6
The book does not say how the pressures were determined, and does not go to greater depths, but it's easy to extrapolate approximate values to moderately greater depths. Several of the Atlantic's deep basins have points between 5000 and 7500 meters deep, according to the atlas I checked, so the pressures you're askingabout could go to somewhat over 2000 mb, maybe up to around 2300 mb. --Anonymous, elevation 130 m (or so), January 8, 2007, 08:44 (UTC).
I'm trying to identify a Hall effect sensor or switch which I am pretty sure is a switch instead of a linear sensor because three of them are recessed into the stator to commutate a 3 phase DC brushless motor through a controller with what I judge to be a square wave from the amount of torque ripple the motor produces under load at startup. Once up to running speed, however, the motor purrs. The only reference I have is a barely visible designation on two of the sensor/switches which is: "F41.5Gc". The "G" in the "5Gc" could be an "0" or a "6" but I'm with 99% confidence sure it is a "G". It is most likely manufactured in Asia, probably China but possibly elsewhere. Allegro sales office says they are not able to identify it and Google produces no reference or clues. Thanks in advance. Barringa 08:27, 8 January 2007 (UTC)
What is the name of the phenomenon in which a radio frequency transmitter transmitting with enough power, causes undesired sound to come from the speakers of and audio system. In every instance that I've heard of it occuring, it was caused when someone has audio system too close to a comercial radio station tower or an amateur transmitter that is using too much power.
Thank you for your help. 146.53.3.4 08:38, 8 January 2007 (UTC)
From The Core article:
- Moving closer to the center of the Earth should result in a decrease in the force of gravity, but no such effect is shown in the movie.
Really? Why? And how would one observe such an effect—that is to say, what would happen? -- 210.246.30.238 10:21, 8 January 2007 (UTC)
For convenience the earth is considered to be a point mass, therefore in calculations like this all its mass is located just at the centre of the earth. Gravitiy is proportional to distance from the centre, and I have forgotted exactly what my point is, but I think I have just disproved it. Or I might not have. Hidden secret 7 20:57, 8 January 2007 (UTC)
The discussion above leads me to wonder: What is the value (in Gs, in the vicinity of the Earth) of the moon's gravitational attraction? ...of the sun's gravitational attraction? It's obviously non-trivial since it leads to tides on the Earth's surface, but I've never noticed the value being stated.

Is Work-Energy theorem valid in a non-inertial frame of reference?
I came across something which seemed peculiar to me - "No work is done by a force on an object if the object moves in such a way that the point of application of the force remains fixed."-Is this true?How? —The preceding unsigned comment was added by 59.93.76.73 ( talk) 14:28, 8 January 2007 (UTC).
What is the word that describes a wild animal that appears domesticated. This usually happens on an individual basis, like a deer you can feed out of hand. There are stories about wild animals that seemed tame, but then just take off for the wild again.
The word isn't taming, nor is it domestication. It is a rare, technical term. I saw it once in 'New Scientist', but I can't remember what it is for the life of me. Can you help?

As I understand it, Darwin explains the existance of so many species by a very slow process of evolution whereby the fittest survive. Did he, or any of his successors postulate any explanation for the fact that, although all species appear to have changed over time, the changes in homo sapiens and the capacities that have been developed as a result of them seem so much more spectacular? Put another way, why has no other species developed the use of language, artistic abilities etc etc beyond a rudimentary level?
This is science, so most of it is random chance. And no other animals have much chance to develop art &c, as they are too busy trying to survive. Hidden secret 7 19:39, 8 January 2007 (UTC)
I think your question is this. Human development accelerate due to positive feedback so how come development of other animals did not enjoy this positive feedback? I believe that it is the development of language and writing that give humans the advantage of positive feedback. If other animal species develop language and writing then they will also "enjoy" positive feedback on their development.
As for why other animals did not develop language and writing, I believe it is because of their body structure, mainly their voicebox and the hands. It is a complete fluke of environment that lead to the development of a suitable type of voicebox and hands for human beings. 202.168.50.40 23:59, 8 January 2007 (UTC)
Why don't snails have wings? Why don't frogs have beaks? Why don't humans have eagle eyes? Why don't worms have four-chambered hearts? We can go on and on about why certain species don't have specific traits. I think the reason primates reign is because we've become so powerful that we've impeded whatever development other species have towards becoming more specialized. In other words, only one kind may prevail, us primates, at the expense of other animals. And who knows, if we let dolphins live they might develop high intelligence like ours in a few million years.
But these are only elementary speculations of mine; check out this part of Darwin's Descent of Man, where he talks about why humans develop complex language while other species lack it: http://books.google.com/books?vid=OCLC00550912&id=sgDHceAj22MC&pg=RA3-PR17&lpg=RA3-PR17&dq=descent+of+man#PRA3-PA87,M1 Read the entire chapter if you like to understand it better. 128.163.241.210
I'm pretty ignorant. So I need help understanding what the deal is with falling objects all falling at the same rate. While I know and can see this to be true (doing some 'experiments' of my own), I wonder why. If all objects fall at the same rate without the influence of air resistance, when why are some of them heavier than others? If I put an object on the scales it might be 'pulled down' by Earth's gravity more or less than another object. So it would seem that the 'hardness' of the force on the object does not affect the speed that it falls at. That's pretty counterintuitive, as if I shove an object in a gravityless (?) environment hard it'll go faster than if I tap it gently (that'd probably a better analogy if I were tugging on an attached string hard or softly, but whatever). So what's the hole in my understanding? Vitriol 19:35, 8 January 2007 (UTC)

Today on new pages I ran across someone who has come up with a slightly different theory of the origin of the solar system. He was trying to use Wikipedia to publish his original thought. I prodded his article and explained to him why it doesn't belong on Wikipedia. Now he'd like me to suggest other places that might be more receptive.

I eliminated strait glucose from my diet well over a year ago by switching to Sweet & Low and a store brand of Aspartame. I “discovered” that if I mix the two in a ration of 3 packets of Sweet & Low to 5 packets of Aspartame that I get sweetness even more intense than glucose except, but maybe not, pure cane syrup or HFCS. Its so intense that I can even mix it with plain sour yogurt and the sweetness takes over and rules. My question before I get side tracked is why is it that when I add this combination to coffee and then sprinkle some cinnamon in that I get a brown oozy slime in the bottom of the cup like extremely nasty sickening snot? What reaction causes this slime and why is there so much of it? I guess ouster lovers could suck it right down but to me it is disgusting. What is it??? -- Barringa 04:09, 9 January 2007 (UTC)
I once heard a counter-intuitive anecdote about making noodles for noodle soup. In Japan, a good noodle factory may add more water to the noodles if the noodles are for take-out use. Possibly, noodles with less water would absorb too much water and become soggy in less time. Is it true? If you have a pasta-making machine you may want to try it. -- Toytoy 04:35, 9 January 2007 (UTC)
At school we frequently tackle momentum probllems using the general equation: mAuA + mbub = mava + mbvb.
To work out the result when two bodies collide using this equation, if they do not coalesce, you need to know something about the result of the collision, such as the velocity of one of the bodies. Knowing only the m and u values, is there a way of working out exactly what type of collision it is, and what speeds the two bodies will move off at?
Many thanks! -- 86.137.233.160 07:50, 9 January 2007 (UTC)

I “discovered” that if I mix the two in a ration of 3 packets of Sweet & Low to 5 packets of Aspartame that I get sweetness even more intense than glucose except, but maybe not, pure cane syrup or HFCS. Its so intense that I can even mix it with plain sour yogurt and the sweetness takes over and rules. My question before I get side tracked is why is it that when I add this combination to coffee and then sprinkle some cinnamon in that I get a brown oozy slime in the bottom of the cup like extremely nasty sickening snot? What reaction causes this slime and why is there so much of it? I guess ouster lovers could suck it right down but to me it is disgusting. What is it??? -- Barringa 04:09, 9 January 2007 (UTC)
I once heard a counter-intuitive anecdote about making noodles for noodle soup. In Japan, a good noodle factory may add more water to the noodles if the noodles are for take-out use. Possibly, noodles with less water would absorb too much water and become soggy in less time. Is it true? If you have a pasta-making machine you may want to try it. -- Toytoy 04:35, 9 January 2007 (UTC)
At school we frequently tackle momentum probllems using the general equation: mAuA + mbub = mava + mbvb.
To work out the result when two bodies collide using this equation, if they do not coalesce, you need to know something about the result of the collision, such as the velocity of one of the bodies. Knowing only the m and u values, is there a way of working out exactly what type of collision it is, and what speeds the two bodies will move off at?
Many thanks! -- 86.137.233.160 07:50, 9 January 2007 (UTC)
