Infinity can be treated as a number (as opposed to just a limit) in complex analysis, which is not really so esoteric as mathematics goes (it's basically just calculus applied to functions on the complex numbers)DrGreg said:*I say "mainstream" because there may be some esoteric branches of "modern" maths that take a different view.

No fission or fusion is fundamentally different from simple "combustion"...It would be better to compare fission/fusion with chemical reactions: the former involved nuclear energies and nuclear mass changes, the latter does not
The mass of combustion products is slightly less than the mass of combustion reactants.
Correct, the binding force involved in chemical reactions is EM, the binding forces involved in nuclear reactions are the strong and weak nuclear forces. Any bound system shows a mass deficit which is proportional to the binding energy. The principle is the same, but the magnitude is obviously much different.Naty1 said:I agree, but I thought the basic difference is that chemical reaction energies come from changes in the electron orbit energies rather than changes in the nucleus, which is true for fission/fusion...is that accurate?
