K^2

from the forum: so none of the quarks in the proton have been there for any considerable time frame? they all just keep getting created and annihilated?

is there anything in a proton that has been there for a considerable time frame?

what do you think this means for the identity of an object such as a proton when all its parts have been replaced?

thanks,

Lee

If I had 2 charged slabs that were moving together at relativistic speeds would both slabs
emit cherenkov radiation. In each of the rest frames of the slabs the other slab is approaching it at a speed that is faster than the group velocity of light in in its material.

you should delete some of your messages in your inbox so I can ask you questions.
Maybe I am asking you too many questions.

Is the spin of a photon just polarization.
To create entangled photons do I just need to excite an atom so it will emit 2 photons at the same time.
If I Electrically polarize a material does it affect the Raman shift.

Hi dear:
Thank you for spending your time. I am looking for reference of such calculations. Can you tell me about your reference.
With Best Regards
