So I have a very stupid question. What is the difference between science and engineering, in the sense that there are chemists and chemical engineers, or computer scientists and computer engineers?
engineers actually do work instead of begging for research grants all day
I kind of grew out of that. I was feeling a little depressed after my poor showing grade-wise.
Oooh, ooh! I can answer the nuclear energy question. Nuclear engineering degree, away!
Anyway, in conventional fission, you have neutrons colliding with nuclear fuel, Uranium-238 enriched with Uranium-235. When the neutron strikes the fuel atoms, they combine creating an unstable atom. Shortly (and really shortly, on the order of 10^-12 seconds), the atom splits releasing energy, neutrons, and fission fragments. The energy comes from Einstein's Special Theory of Relativity (E = MC^2). Simply put, the mass of the neutron and U-235/238 is greater than the mass of the fission products and neutrons. The difference in mass is released in the form of energy.
Yes I understand all that, and that there is a difference between the starting mass and the mass at the end, and that difference is the amount of energy released from e=mc^2, but what actual particles get turned into energy?

Isn't that kind of like asking where the electron is. As in we don't know.

A good source of isotopic masses in atomic mass units (amu) is Wikipedia (just search for "isotopes of ____"). Using my previous example, assuming Xenon-140 and Strontium-94 to be the fission fragments with 2 neutrons produced:

We don't actually know this one. Einstein said that gravity is a side-effect of the distortion of space-time by matter, but quantum physics requires there to be some kind of mediator particle (the graviton). Quantum mechanics has explained away all the other fundamental forces (electromagnetism, and the strong and weak forces) but not yet gravity.
One of the problems here is that while General Relativity is really good at describing gravity on a large scale, it's not very good on a quantum scale. However, the graviton has so far eluded discovery by even the brainiest of scientists. That, and the two theories are fundamentally incompatible.

Given there are 931.5 MeV/amu, the total energy released from one fission is ~184.7 MeV.
So you see, no particles are turned into energy. The amount of elementary particles before and after the fission is the same. The energy that is released is the energy that binds these particles together. As far as I know, anyway.

Quite correct.
Imagine two pieces of velcro stuck together. When you tear them apart you get the audible ripping noise. In terms of fission, you are the neutron, the velcro is the target nucleus (comprised of the two pieces of velcro), and the noise is energy.
That wireless energy transmission discovery was actually partially inspired by Tesla and many of the things they discovered are believed to have been put into use by Tesla himself and not reproduced until now.

we all now that is cool and that but anti matter is where its at, thats where E=mc^2 comes more in handy as anniahlation cause's the matter to be converted directly into energy, for example assuming the rest mass of a proton is 1.67 × 10−27, then to anniahlate a proton it would produce:
2x(1.67× 10−27 )x3x10^8=1.002x10^-18 Joules ,
which doesnt sound like a lot but one mole of protons which is about 6x10^23 of them plus the other mole of anti protons would produce 6x10^-5 J and thats not even a whole gram
, CERN has calculated on their website that only Half a gram of matter anniahlating is equal to the bomb dropped on heroshima

n + U-235 -> Xe-140 + Sr-94 + 2n
n = 1.008665 amu
U-235 = 235.0439231 amu
Xe-140 = 139.92164 amu
Sr-94 = 93.915361 amu
So...
235.0439231 + 1.00865 - (139.92164 + 93.915361 + 2*1.00865) = 0.1982721 amu
