Is there a book on it or web page. Example broad band sun light falling on a solar cell gets a electron but I do not want the reaction from the broadband light say I want the reaction from 1.6 micron, so what elements react at 1.6 micron or other defracted wave lengths to produce a electron to indicate the presence of the target.

we take acual volumes occupied by the molecules but actual pressure exerted by the gas is less, then why dowe add some constant to make it ideal pressure, when this corrected equation is meant for real gases.

I read the other day that some people think there is a planet exactly like earth, in our same orbital pattern exactly on the opposite side of the sun. It can never been seen because of the sun, and can never be verified because of the flight patterns of space vehicles (Hubble space telescope etc) are always sent in the opposite direction. Has anyone read about this? Hey...anything is possible.

I think it's part of denmark but does it count as a country? The World Factbook has Greenland in it's own entry.

Is it possible to create a generator for home use that A. can power the average needs of a home while at the same time creating enough energy to power itself. B. can it be made small enough to be stored out side the home like a central air unit. I ask this because if it could be done it would solve the need for consumer use of oil and electric at the same time making each home self sufficient. It would also save the average home owner thousands in the long run. I believe it is an invention whose time has come. Any and all logical ideas are welcome.

I know someone who has a theory that when sufficient methane has been absorbed into water particles from methane hydrates being released into the atmosphere, and freezes into hailstones the head of a storm, it will fall as burning hail. Can anyone give me a contact to verify this theory?

Out of two, a heater of 2kW and a toaster of 1kW, which has greater resistance?

There are two formulae of power :-
First is P=I*I*R (According to which P is directy proportional to R)
Second is P=V*V/R (According to which P is inversely proportional to R)

This question was asked in my physics exam today. I am in doubt. Please help...........

i do not believe in it one bit. go on yahoo! search and look up "moon landing". all of the pictures were from when it was shot in a studio. please do not tell me "oh you think they're all lieing now?" when yes, the entire government is a huge lie and you know it. also, where are all the recent pictures of landing on the moon? i think everyone needs to look at the pictures and you can tell how fake it is all when you just LOOK at them. dont answer this question if you did no research and looked at no pictures. so what do you think, did they or not?

I am currently pursuing a degree in Computer Science, and I'm becoming burned out on programming. It isn't rewarding to me any more, so I was thinking of changing my major to Computer Engineering. Has anyone done this? What sorts of jobs are available for computer engineers? Has anyone done both and can offer advice on which was better?
