I am curious how exactly fundamental measurements are made for subatomic particles. I am hoping someone who knows can point me to some references as to the following:
1) How is the position of a photon measured?
2) How is the position of a subatomic particle measured?
3) How is the momentum of a subatomic particle measured?
4) How is the energy of a subatomic particle measured?
5) How is the mass of a subatomc particle measured?
For 1) I got an answer about NIST's device that cools the environment to absolute zero and then registers a small change in heat as the position of the photon. Is this really the best way to do this? What other techniques are there?
for 2) and 3) I can follow the Heisenberg argument about registering the change of a path of a photon to register the position of the particle and finding the change in momentum by recording the change in wavelength of the light used to detect the particle.
If there are more modern ways to do this though I would appreciate the information.
The other quantities I have no idea about how to measure these.
I am more a math guy than a physics guy so the actual experiments to determine these properties are foreign to me. I would appreciate any help though.
Thanks in advance.
