I love to program and crosscompile baremetal C programs for ARM based microcontrollers, I love physics and i love writing science documents/books in LaTeX. It amazes me how physics is connecting all science and is helping mathematics to evolve. In order for science profession to comunicate on a high level i advise everyone to use Linux, LaTeX and a good vector imaging program like Inkscape.

comment positron / electron annihilation - where is the invariant?
I am sorry but I don't understand. Is it different fi I say the Lorentz invariance is: $E^2={E_0}^2+(pc)^2$ or if I say: ${E_0}^2 =E^2-(pc)^2$? It is the same equation. Is above example solved correctly?

Thank gosh! I am so happy now, because i think i understand this :). What about if the kaon would spolit into two different particles with different mass and speeds. Look at the EDIT.

comment The probability of finding the electron in the H-atom
So this is the full probability... What if i was looking for $P d\theta$? Would i just have to remove the $\int\limits_{0}^{\pi}$?

comment The probability of finding the electron in the H-atom
I know if i want to get the full probability i need to calculate: $$P=\int\limits_{V}|R(r)|^2|\Phi(\phi)|^2|\Theta(\theta)|^2dV = \int\limits_{V}|R(r)|^2|\Phi(\phi)|^2|\Theta(\theta)|^2\,\,r^2dr\, d\theta \sin\theta d\phi=\\ =\int\limits_{0}^{\infty}r^2|R(r)|^2dr \int\limits_{0}^{\pi}|\Theta(\theta)|^2 \sin\theta d\theta \int\limits_{0}^{2\pi}d\phi$$ I hope i wrote that right and i think that this full integral should equal 1. But somehow it is still not clear to me how to get the $P(r)dr$... How can i interpret the $dr$ after the $P(r)$. What do you think of when you see something like it?

I have one more question about this. Why did we use the diferential of volume when we are searching for $P(r)dr$

comment The probability of finding the electron in the H-atom
Thank you very much. So if we are satisfied with a fraction of a probability there is no need to integrate :) What confused me was that feeling that if we want to integrate the equation we have to do it on both sides and not only one side... It is weird to me that we integrate just part of the equation.
