I can rewrite that equation with brackets
(E)^2 = (pc)^2 + (mc^2)^2
tells me that E must always be greater than pc, where p = |p|. This is ONLY true if m is non-zero, because if m = 0, then E = pc.
So, in my final equation, have
2(E+)(E-) + C = 2(p+)(p-)cosx where C = (mc^2)^2...
ok, I think I finally got what you are saying. Its making sense. The picture is forming correctly for me now. I tried balancing equations and one last question remains though:
When you guys let c = 1 in E^2 = p^2*c^2 + m^2*c^4, could I be able to show that E^2 is always larger than p^2*c^2...
Thanks, that rest term should not be there. I think I understand some part of the Meir's post now. Here's the way I understand it...my question is at the end:
E^2 = p^2 c^2 + M^2 c^4, where M = m[0]
let c = 1
I can see that it must hold for the conservation to be valid. Just to...
For both energy and momentum, I have moving photon + Rest term = sum of 2 energies + rest term.
Perhaps, I need to back up: What does the earlier post mean physically when the following is said:
"For a photon, E^2-P^2=0.
For any number of massive particles, E^2-P^2>0."
What is the...
Perhaps I;'m not correctly understanding what is physically going on. I can see that |p(photon)|=E(photon), so that part is fine. But I am confused about the other two equations:
|p(e+)|<E(e+)
|p(e-)|<E(e-)
How do they come about in relation to this problem? Also, why does...
Are you saying that because E^2 + p^2*c^2 = m^2*c^4? This way since m^2*c^4 is always greater than zero, the left side must always be non zero. But , how does this show the connection to interaction?
Also, I should calrify my equation:

Exactly! I would highly recommend speaking the professor as each University/College teaches different material in similar courses and that could have different effects on different students.
His feedback should ultimately be the deciding factor for you, when deciding whether to take or not...
