And when i say small, i mean half the size of my hand. Do they even make them like that? I don't know. I'm certainly no expert on the subject. But i've got a great idea and need to find one that size. It doesn't need to be very powerful. To give you an idea, way more powerful than ones in toys, but not near as powerful as the ones in fans.

I know that at the "start"of the BIG BANG no cesiumatom existed.So "time"could not be expressed,certainly not by an atomoscillation.The reason of my question was that often I read:"one second (or one minute,hour,etc)after the beginning of the BIG BANG..." What is the meaning of such a statement?And when the first cesiumatom was born I suppose that "matter"was still extreme dense.I presume that 1 oscillation of that atom "then"would have been many oscillations of an cesiumatom in "ANOTHER WORLD"where there also have been a"BIG BANG" but very very earlier". RESUMED:"1 second,minute,etc"When I read such a statement in a "scientific"article I become puzzled.Please answer only seriously.(Jokes I know enough)

in simple terms what is nanotechnology and will it have a huge impact on the world, also can it be used in conjunction with light as this also seems to me to be what science is concentrating some effort on?

I recently read a new planet was detected 450 lighyears, can it be possible that the planet doesn't exist anymore? and we are just detecting the light that was projected by it. If what we see is what light reflects then wouldn't scientist be detecting a planet that was there 450 years ago. In other words if someone is in that planet right now looking at earth, wouldn't that person be looking at the very past?

Why both Earth and moon must rotate about the common centre of mass rather than the moon about the centre of mass of Earth?

Intro: Astronomical observations show that the centre of mass of the earth moon system is 4.7x10^6from the centre of the earth.

When I was at school, my Maths teacher showed me a way to decipher the correct moves for the TOH. He wrote out the binary numbers in sequence, and then "read" them. I think it went from right to left? This would show you which moves to make for minimum number. Does anyone know of this technique please?
