No. You can do QFT in flat or curved spacetime. -
Only in the sense that QFT gives a mechanism for computing probabilities that doesn't have the collapse postulate the way ordinary...
-
You don't need to "master" relativity. You just need to understand that one of the lessons relativity teaches us is that physics is...
-
That's correct. What you are calling "ordinary" QM is a non-relativistic approximation. For relativistically correct QM, you need...

You're certainly not the only one. :wink:
-
That's correct. Not really. See below. Yes, but what that means is not that "you can think of the wave function collapsing either...

You may conclude that that statement, as you make it, is not even well-defined. You didn't specify a time in any frame at which B has...

Note that any point on the unit circle has coordinates ##(\cos \theta, \sin \theta)##. This is perhaps the simplest way to define sine...

People dont use the unit circle for these kinds of problems instead they use trig identities to reduce it.

No. You have a system consisting of a particle and a measuring device. That's true regardless of what outcome you measure. The sentence...

What in the math of QFT corresponds to "the thing that is out there"?

By quantum field i didn't mean the operators, i meant the thing that is out there. I thought that there are no interpretational...

bhobba replied to the thread Undergrad One does not “prove” the basic principles of Quantum Mechanics.That's why I used the word compelling. One can still maintain the fields of QFT as just a calculational aid. Indeed, the Effective...
