Excellent, thank you very much for the great reply. I am currently brushing up on my group theory. I imagine I will have a follow-up question, but while I continue to digest everything, I just wanted to say thanks! I think one of my problems was how I was thinking of the Lorentz Group as a...

I can try. I know a little. Give me your best shot, thanks.

I am reading Quantum Field Theory by Michio Kaku, and I have come across some equations that I can't quite make sense of. I am hoping somebody can help me out. Please see attached. Thanks.

Oh, sorry I didn't mention it, but the pic on my last reply contains further questions if anyone can answer them. Especially the one at the end. Thanks.

Okay, cool, this is great.

Okay, I did a little more research and found something, which I hope to be true. Lemme revise my earlier question according to the attached.

Hi, I some basic questions on the physical meaning of bra-ket notation. I have looked at a lot of material, and I have seen descriptions of the algebraic properties of bra-kets, and I have seen hints at it having meaning regarding the probability of events happening/state changes, but I can't...

Thanks, I just ordered the book off of Amazon. Okay, I think I am comfortable with the mathematical derivation of the creation and annihilation operators. But I am still having problems understanding how both the position and momentum fields, and the creation and annihilation operators...

Apparently my first three images didn't attach. woops.

I could only attach three images, so here are the other two...

I am trying to understand the canonical quantization of the Klein-Gordon equation and I am quite mixed up. I have been going over the same equations for over a week now and getting nowhere. My main textbook is Quantum Field Theory: a Modern Introduction by Michio Kaku, but I have been scouring...

Thank you! that helps.

Hi, I have a basic question regarding the commuter brackets. Basically, what does the syntax mean? I understand that in general, [a,b]=ab-ba, but I am confused as to how to make sense of that with fields. I am currently reading up on the quantization of the Klein-Gordon Equation, and I ran...
