Can anyone tell me the reason why an enatiomer rotates the plane of polarised light? Or at least tell me where i can read more on the reason why some compounds exibit optical activity.
Thanx

Sound waves and frequency
In my opinion, the answer is that frequency affects directly to the velocity of the sound.
Therefore, high frequency sound have high velocity.
Can someone post if this is right or not? If not, can anyone provide the correct answer? Thanks in advance.
I was thinking about how gravity is used as an energy source, for instance, gravity pulling water over a wheely-thing produces hydroelectricity. I wondered if there was a way to perpetually use gravity as a continual source of energy without the normal catch -- water can only fall once before...
A physicist said that the reason why the chair is able to hold my weight is because of Heisenberg's Uncertainty principle. His reasoning was that when the atoms of my body are in contact with that of the chair, the electrons in the my body push against the electrons in the chair. Thereby forcing...
After lugging these things around for over twenty years now, I just got rid of about six hundred pounds of industrial manuals. Thanks to the internet they are no longer needed. I also realized that for the first time in my life, I can start to reduce the amount of shelf space dedicated to books...

I know it is not a science book only and maybe there is not too much to discuss here, but I just wanted to know if anybody has read it. If you have, would you share your opinion please. :)
I'm unsure what I'm doing wrong here... it has to be something. So let me explain the problem:
I'm supposed to rank the net magnetfic field strength for various arrangements. In all of the arrangements the magnitude of the current is the same. The distance between each of the charges is the...
We are on generators here, but it looks like everything around us in Westwood is without power. Trying to get home tonight should be interesting. :frown:
THE THEORY OF GENERAL RELATIVITY states that the gravitation is due to the fact that the heavenly bodies create a sort of dent in the spacetime fabric.
Now,
WHAT IS THE REASON THAT THE HEAVENLY BODIES CREATE SUCH KIND OF A DENT?
Let us for example take an elastic sheet and place...
I found this exercise in an old physics schoolbook. I maeged to solve it but I don't really understand why I have to solve it in this excact order. Before I start I would just like to add that I have very little experience with differential equations (they are not in our high school year plan)...
This obviously need to be revised to make it more congruent and readable, but I would like to know what people think of the reasoning behind it...

As we all know, the United States is No1 leading country in the science and technology in the world. Is this because of its quality of education system? What do you think ?
My friend, a former bush pilot, just e-mailed me the following item. They're all true quotes, or at least as close-to as they were remembered.

i think that the reason of hot water 'float' on the cold water is not becuase of diffrent density. i make a model of a container containing a higher energy particle (hot water) and lower energy particle (cold water) using action script in flash and uploaded it in geocities...
Evening everyone,
This is a rather odd question: why do we yawn? Is there any biological reason for it? Why do we yawn when we see other people yawn or think about it?
Oh, just typing this post is making me yawn! :zzz:
Obviously there is a reproductive reason for the male orgasm, but why do females orgasm? Of course in our culture it is a pleasurable thing, but biologically it seems like most things in the reproductive system serve to actually help reproduce in some way. Is there a reproductive reason for...
It occurred to me that people seem to be the only things that reason, or make sense of the universe to some practical end, and perhaps other life on Earth to lesser extents. So why reason? In the end after we have developed everything to develop, every technology and every form of thought, in...
There is truly no reason not to get a mac as far as I'm concerned. The hardware is great, the software is great and now with the new mac mini the price is great. Besides games anything you want to do on a windows pc you can do on a mac. Even when you talk about games, any game that's worth...
Earth born for some reason ? it born with some propose?why?
is it really just like what ppl explain ,dust mix with...blar blar...
if it really being created ,what is the reason?
There is no net gravity in a hollow sphere. You can get this result using calculus but that's not really understanding it. There must be some special property of the hollow sphere which is unlike most, or all, other objects, because most or all other objects do not have zero net gravity in...
ok, this may be a stupid cuestion, but it has gotten me very curious, and if somebody could help with it, I would appreciated very much thanks.
Ok here it goes, why do we equal equations to 0 (zero) for example (quadratics ones) y don’t understand why, I have some ideas but I don’t know if...
Hi All,
I am not very much familiar with Physics but i read some physics in my Engineering education days. Surprisingly, i am getting more & more attracted to Physics , particularly astrophysics ( relativity ,...etc ).
I read that Earth has gravity G with certain value. Per Einstein, space...
how do we know that reason is right ? to take an example from the ancient islamic philosopher al-ghazali (who used it to support a need for God and divine support (though I might not go the same route)), if we lacked reason, we would assume that the senses are correct and accurate; reason shows...
Why logic and reason fail when we try to trace back the origin of universe!
When we try to think what might have created the universe,when was it created,how,why,where etc etc, the parameters we are looking at are TIME when we say WHEN and SPACE when we say WHERE,HOW,WHAT,WHO.
Out of the ten...
Is anybody else here confused? In my town half the people seem to believe black, white and grey are colors? Could anyone clarify? Much obliged...
A color or a shade?

Well let's say we put it this way. There is a reason for everything, right? If so, then that must put reason high and above everything else on the list then, right? So what else can we possibly conclude, except that reason is God...
Hi, I was just wondering what the actual proof is for the second law of thermodynamics that would disprove a situation where all particles are simply reversed in direction creating lower entropy? Is it a consequence of another scientific principle or where does it come from?

I've read many posts in these forums defending and debunking creation but I don't think that anyone has mentioned this simple reason why not only creation is false but evolution is the only rational truth.
It is a simple biological fact. A healthy population of a unique species can not grow...
On the issue of a Constitutional amendment to ban gay marriages:
Even though most of us know that this is nothing but a distraction since there is no way this could never pass the 2/3, 2/3 needed, much less ratification by the states, the Bush logic is worthy of review.
Premise: Marriage...
I wrote a lab report for my physics class and i can't finish my conclusion. In conclusion, I have to write why the results i got was so off and so far i have only two weak reasonings. If any of you can see better or more reasonings, please leave me a comment and elaborate a little bit if you...
I don't quite support the American expression:"We have a reason to believe" cause I don't think it's enough.What's your pick:
-I have a reason to believe?
-I have no reason to doubt?
This reasons are:
1) BB expects shaping 3D space from 0D zero point. This impossible.
2) BB expects the expansion of space at the speed of light. If BB began with flashes of the light, then the universe on today look like empty sphere by radius 10 billion light years with the background...
Just idle wondering, but I think this is something that may need to be addressed.
Why do we trust reason? What is reason? Is reason really limitless?
On one hand, we can see reason as purely a notion we receive from observation. We see this pattern, and we store it in our minds. However...
This is written by Geoffrey Heard C 2003, not me. I know its long, sorry about that, but as I said: I didn't write it! [:p}
Read the first paragraph at least, and then if you are at all interested in this sort of stuff, then the rest is really worth reading. I am not all that interested in...
