What would happen if you were to mix two types of blood groups? —The preceding unsigned comment was added by 24.6.87.25 ( talk) 00:07, 3 May 2007 (UTC).
If the half life of a substance is 60 hours and after many many many hours later, the drug is down to it's last molecule. What does the "half-life" of 60 hours mean physically for a single drug molecule? Does it mean that 60 hours later, there will be half a molecule of that drug? 202.168.50.40 00:27, 3 May 2007 (UTC)

My crackpot chiropractor said to me that the tendons/nerves in a female just "snap" back to their place when stretched, whereas males after they have been manipulated their tendons etc tend to stay like that more easily. However ultimately I'm not sure. Rfwoolf 12:22, 3 May 2007 (UTC)

Greetings,
Your picture of white light separating into the colored light shows a prism with a very strong source of light to make a very prominent color spectrum see -- http://en.wikipedia.org/wiki/Color_spectrum. However, the picture did not say what is the source of light used. Can you please tell me what is the source of light used to make such a strong color spectrum and where can i get it? I used large flashlights and small flashlights and you can barely see the color spectrum because the light was not strong enough. I am now looking into photography lighting and believing for the best.
Thank you.

Coupla thoughts: What's the frame of reference for declaring that a period of 24h is "fast"?—the earth is pretty light and small on a cosmic scale. Need to be careful that a reasoning of "they should average out" doesn't wind up as a Law of averages fallacy for one specific collection of particles (i.e., "Earth"). By conservation of angular momentum, a large disk spinning slowly becomes a small disk spinning more rapidly— moment of inertia scales as r2, so cutting the diameter in half increases ω by a factor by four.

I'm from South Africa, and I'm not sure what you're referring to. Certainly in the urban areas such a thing is highly unlikely. What you're probably referring to is a type of herb or roots or something. There's sugar cane which you can chew and suck on and spit out. Maybe you can give us more information. Are you sure it was a "Grass" ?

A few years ago I saw a bluish heron in Northern California and was wondering what kind of heron it was. It was not (from my memory) a Great Blue Heron. 67.172.125.250 03:39, 3 May 2007 (UTC)
Hi. What is an electric control device? Thanks. -- Mayfare 04:39, 3 May 2007 (UTC)
I have four questions which are linked
1. Given a typical* modern power station, what kind of yield in terms of watts does a ton of uranium produce.
2. Given a typical* modern uranium mine. How much fossil fuel does it require to mine and transport a ton of uranium.
3. Given a typical* modern fossil fuel power station how many watts would the fuel equivalent to the answer to question two produce.
I hope you can see what I am getting at.
4. Seeing as there is no obvious substitute for fossil fuel in the mining/transporting of uranium and the construction/decommissioning of power stations. Could nuclear power be defined as a convoluted way of turning fossil fuel into electricity?
Hope that's OK

As you all know, if you can hear a loud noise, you have to shout to people that are stood reasonably close to you in order for them to hear you, even though they would normally be able to hear you if you spoke normally when the noise was not being made. Is this still the case when the noise is inaudible (i.e. it has a pitch of over 20,000Hz)? In other words, is the need to shout generated by the actual vibration of the air, or by the overloading of the human ears? -- 80.229.152.246 14:05, 3 May 2007 (UTC)
Thanks for the info. I forgot about the fact that waves don't interfere with one another. -- 80.229.152.246 19:35, 3 May 2007 (UTC)
As far as I understand a parachute works by causing air resistance and thereby slowing the object that it's carrying down, it also seems to me that it's the ratio between air resistance and weight of the parachute and the object the defines your fall speed, so my question is: How do you calculate the air resistance needed to slow an object to a certain speed?
Second question: How big does a parachute have to be to cause a certain level of air resistance? Thanks for everything, Jeffrey.Kleykamp 14:10, 3 May 2007 (UTC)
As far as I understand a black hole's gravity bends light and right before the event horizon you see light coming from your position, so my question is has anyone tried to look at the light that left earth a long time ago, say 100 million years, by looking at a black hole that's 50 million light years away, I know it could be hard, maybe even very hard, to find a black hole that's exactly 50 million light years, but that's not the question. And I also understand that the light won't look like a crystal clear picture, and more like a line, but computers can calculate away any errors. Thanks for everything, Jeffrey.Kleykamp 14:34, 3 May 2007 (UTC)
Also: unfortunately, black holes are quite far away. After a bit of searching on Google, the nearest black hole seems to be about 1600 lightyears away. After a bit of rough calculation, this would mean that the Earth would have an angular diameter of about 8x10-13' (or if you don't like scientific notation, about 0.0000000000008'). When you consider that the Sun has an angular diameter of about 30', you can see how small that is. As such, only a piddly (yes, that's a scientific term) amount of light would reach the black hole. Even if the improbable event of completely accurate bending of the light could occur (even the tiniest error would result in the light that has been bent from the black hole from reaching us due to the large distance involved), there would not be enough light there for us to detect. I hope that answers your question. -- 80.229.152.246 15:13, 3 May 2007 (UTC)
If we were looking at a green chair, how do we know that blue and yellow are being absorbed and not green? All three of these colors are on the electromagnetic spectrum, correct? Nick 16:27, 3 May 2007 (UTC)nicholassayshi
The short answer is that you can't tell, by looking at it, whether the colored light that you is "pure" or a mixture of two other colors. When you see yellow on a computer or TV screen, for example, it's typically a mixture of red and green. But it looks the same as a pure yellow light. That's simply how the human visual system works, which is what all the links above are about.
In the case of a typical screen, the red and green light actually comes from separate colored dots, so if you look very close at the screen you can tell. But in general, if the mix of red and green was coming from the same source, the only way you could tell it isn't pure yellow is to apply some sort of instrument; for example, a prism that will separate different colors of light. --Anonymous, May 4, 2007, 00:35 (UTC).

I've just bought a new battery for my phone after having problems with a poor memory on the last one. I know I'm supposed to charge it for 16 hours the first time but should I just do this straight away or should I drain the new battery before its first charge? -- Kiltman67 17:27, 3 May 2007 (UTC)
A kite makes a force(lift) to stay up, so I'm wondering what's the relation of the string's angle to the ground, I'm guessing that at 45° the kite is using half it's force to stay up and the other half to pull and move the holder or if it can't, it transfers the energy to the lift or simply losses it, so is it just a right triangle with the hypotenuse being the total force, and to find out the force on the horizontal part you solve for the bottom of the triangle and the vertical force you solve for the right part of the triangle? Thanks for everything, Jeffrey.Kleykamp 19:33, 3 May 2007 (UTC)
I don't know the correct terms but I know that there are several species of birds in which the males are multicolored and "flashy" compared to the females. Are there other species (besides birds) that have the same attributes between male and female counterparts? Are there species that have the females possessing these physical attrubutes instead of the male counterpart? —The preceding unsigned comment was added by Juliet5935 ( talk • contribs) 19:46, 3 May 2007 (UTC).
Thank you, Adam. That was what i was looking for!
Kiltman, are you sure about that? I thought most bird species were seasonally monogamous, since taking care of the children requires the cooperation of both parents; one to sit on the eggs, and the other to bring food.-- Kirby♥ time 06:31, 4 May 2007 (UTC)

Steve, what do you mean by the classical experiment? One of the earliest attempts to measure the speed of light was Galileo; he used the hill/lantern method, which admittedly is very poor as it relies on human reaction time. The first time the speed of light was measured within a reasonable accuracy was by Ole Rømer, who used Jupiter's moon Io to pin down the speed of light to around 140,000 miles per second (compare that to the modern value of 186,282 miles per second).-- Kirby♥ time 06:26, 4 May 2007 (UTC)

A more clear question please...?
At the end of one of my experiments doing an acid and base titration, I converted the moles of HCL to moles of NaOH using a stoichiometry problem with the equation of HCL + NaOH -->NaCl+ H20.
My question is: Why are these acid and base titrations done like stoichiometry problems?
Please help, thank you! —The preceding unsigned comment was added by 76.188.176.32 ( talk) 21:39, 3 May 2007 (UTC).
Someone mentioned something a while back about how their parrot would shred an entire orange, just to get at the pips inside and completely ignore the fruit. I noticed something similar today with my hyacinth macaw when I gave her a slice of watermelon. Instead of doing what I would, eating the flesh and spitting out the seeds, she did the opposite. To her, the fruit was just something to dig through and fling away to get at the yummy(?) seeds. She made a real mess, as she always does. :)
Probably related to my question - if I give her a chicken drumstick (it's good for her to eat meat every so often), she doesn't seem to be that interested in the meat itself. She tears most of it off and thows it on the floor. Then she cracks the bone and goes for the marrow.
Any ideas why parrots have such different opinions to us on what is 'food'? -- 81.77.94.75 23:53, 3 May 2007 (UTC)
I see this as a two part questions:
1) Why don't humans tend to eat seeds ? This one is fairly simple, people don't get much from seeds with hard shells, as they tend to come out much the same way as they went in. In order to open the shell, people would need to gnaw on them, possibly wearing down their teeth in the process, for very little food benefit. Many birds tend to have beaks or stones in their crops designed specifically to break through the hard shells of seeds, so can make use of them.
2) Why don't parrots eat the flesh of fruit ? This one is a bit harder, and will require speculation on my part. I would guess that they can't handle all that sugar at once, lacking the large pancreas of humans which can rapidly release insulin to counter the sugar rush. They might also get diarrhea with such a diet, not being designed to handle all that moisture in their food. Another factor might be that birds which fly can't afford to be bloated with water, even temporarily, due to the added weight. StuRat 00:07, 5 May 2007 (UTC)

Regardless of if it is, theoretically which part of the mirror would be on the outside, the mirror side or the seethrough side? —The preceding unsigned comment was added by 71.185.139.138 ( talk) 21:06, 3 May 2007 (UTC).
A more clear question please...?
At the end of one of my experiments doing an acid and base titration, I converted the moles of HCL to moles of NaOH using a stoichiometry problem with the equation of HCL + NaOH -->NaCl+ H20.
My question is: Why are these acid and base titrations done like stoichiometry problems?
Please help, thank you! —The preceding unsigned comment was added by 76.188.176.32 ( talk) 21:39, 3 May 2007 (UTC).
Someone mentioned something a while back about how their parrot would shred an entire orange, just to get at the pips inside and completely ignore the fruit. I noticed something similar today with my hyacinth macaw when I gave her a slice of watermelon. Instead of doing what I would, eating the flesh and spitting out the seeds, she did the opposite. To her, the fruit was just something to dig through and fling away to get at the yummy(?) seeds. She made a real mess, as she always does. :)
Probably related to my question - if I give her a chicken drumstick (it's good for her to eat meat every so often), she doesn't seem to be that interested in the meat itself. She tears most of it off and thows it on the floor. Then she cracks the bone and goes for the marrow.
Any ideas why parrots have such different opinions to us on what is 'food'? -- 81.77.94.75 23:53, 3 May 2007 (UTC)
I see this as a two part questions:
1) Why don't humans tend to eat seeds ? This one is fairly simple, people don't get much from seeds with hard shells, as they tend to come out much the same way as they went in. In order to open the shell, people would need to gnaw on them, possibly wearing down their teeth in the process, for very little food benefit. Many birds tend to have beaks or stones in their crops designed specifically to break through the hard shells of seeds, so can make use of them.
2) Why don't parrots eat the flesh of fruit ? This one is a bit harder, and will require speculation on my part. I would guess that they can't handle all that sugar at once, lacking the large pancreas of humans which can rapidly release insulin to counter the sugar rush. They might also get diarrhea with such a diet, not being designed to handle all that moisture in their food. Another factor might be that birds which fly can't afford to be bloated with water, even temporarily, due to the added weight. StuRat 00:07, 5 May 2007 (UTC)
