p_{\varphi}=mr^2 \dot{\varphi}, \quad m=\frac{m_{0}}{\sqrt{1-\beta^2}}, \quad \beta=\frac{v}{c} that first bit about momentum, where is that from?

I was looking at the relativistic energy of an electron and noticed that the formula for kinetic energy is: K.E. = mc^2 -m0c^2 How is this related to the kinetic energy for low speed particles? Does anyone have a link to the proof?

yea sorry I meant the helium ion. How would you go about applying relativity? Velocity is an unknown at this point isn't it?

can someone explain how bohr used the mass of the nucleus in helium to develop a ratio of 4.0016 of the original rydberg constant for hydrogen? I can't seem to find the proof anywhere, I read vaguely that he found this value by calculating the increased charge in the nucleus and using the mass...
