if fission and fusion provide energy,why is it not possible to start with a nucleus,make it undergo fission and fusion repeatedly and continiously ,and obtain large amount of energy ?besides ,if it is possible ,all the energy we require can be satisfied by a single nucleus undergoing fission and fusion.

Haha, sorry! Helping my little bro again, and he came across something else I didn't remember.

OK, please explain steps and how to answer questions like the following. Solving for X.

5=20/X (5 = 20 over X. I know the answer, just not how I got it, he needs to show his work)

And this one:
cx/a = b/m (CX over A = B over M).

Also, do any of you know a good website that he/I can look at for help when we need it? Thanks a lot, guys!!!

How accurate is the science in that show? They throw alot of terms, acronyms, etc around. I just wonder if it's based on real science or goobledegook. It's a Canadian show so mostly canucks (and people with Bittorrent ;-P) would know of it. It's really good but science-heavy.

does it actually exist? think about this, we only "sense" objects, whether through our sense of touch, smell, taste, sight and hearing, which is then translated to the brain to form a picture or shape or sound of an object....so, my question may seem far out there, but are our brains only creating these objects from data that it receives?...and in reality we only perceive and "see" and "feel" etc. these objects in our mind's eye?.. Do objects cease to exist if there is no brain there to sense it?...

light is invisable untill it reflects off some thing
the darkness disapears when light shines off things
no things the light just remains unseen untill it reflects of anything
that reflection og light is only because the atoms distorting the waves of light by interferance of the light and the orbital planes
of the electrons of which the seen object consists of
the quality /quantity frequency of the orbital electrons and protons setting up the spectrun of visable light
also i feel light is strictly speaking particle that gets released in waves
that light electron that hits an object causes the opposing electron to continue in the same direction that the given electron then is continually changes at the atomic level despite seeming to be light comming from far away the actual electron we see is as an effect much as a wave in water is a passing affect
that the water molicules making the wave pass on the wave yet the water perticle remains stationry

In the mitochondrial electon transport chain, electrons flow energetically downhill from NADH to oxygen and reduce it to water. In the cholroplasts' electron trnsport chains, electrons that come from the splitting of water flow energetically downhill and reduce NADP+ to NADPH. Being that the elctrons that reduce NAD+ and NADPH have aprox. the same reducing power. How is this possible?

what if air pressure is only caused by forcing the orbiting neutrons and electrons orbital planes into a lower orbit
what happens when orbital planes are forced into contact ,are forced into closser and lower orbits
eventually they would change state?
but when released reform instantaniously into air but in thier changed state want to remain sepperate but eventually forced into the field of affect s interacting with each other
say it better if im wrong
i see it as forcing two magnets to gether both pushing appart yet being forced to gether ,same as air presure pushind other orbiting fields of affect
