    Graduate Calculating Offsets on the Normal Coordinate System

    I don't understand your answer. Its actualy using quanternions for rotation but i used euler becouse i thought it will be easier. I am really not good at math so if anyone could explain answer or give me example it would be great.

    Graduate Calculating Offsets on the Normal Coordinate System

    I have problem with getting normal coordinates offset. I have cube1 and cube2. cube1 position is 10,10,10 and cube2 position is 10,9,10. Cube 2 offset refers to local coordinate system of cube1. If rotation of cube1 is 0,0,0 i get position offset 0,-1,0. But if cube1 rotation is 45,0,0 i get...

    Coulomb Potential Barrier: Is This Calc Right? What's fm?

    The Coulomb potential barrier of a system of two nuclei X and Y is approximately given by VC = ZX*ZY*e2/RN where ZX and ZY are the charge numbers of the nuclei, e2 = 1.44 MeV*fm, RN = (AX1/3+AY1/3) × r0 is the sum of the nuclear radii. r0 is a constant usually estimated to 1.2 to 1.3 fm and AX...

    Graduate Fusing Deuterium: The Mystery of Ejected Protons/Neutrons

    In fusor you react one deuterium with another one. So you should get [SIZE="1"]4He[SIZE="1"]2. Why does it ejects one proton or neutron from nucleus?
