Physics is partially difficult, but as a whole, it is understandable.

This is made up. The field? You mean the electron shell? You can't just make up a word and talk about things that in the end amount to nothing. You put an T for time and S for space the come up with T/3.14= S-1. And as you see people. It all makes sence! You are just dealing with abstracts that dont matter. Make me an affordable electric car smarty. Do something I hate people who just run their mouth! You can't even change your motor oil.

"This is made up. The field? You mean the electron shell? " Dr. Susskind is explaining QFT . Fields ,BTW, ARE well-defined in physics. Electron shells only apply to atomic models- that's not what is being discussed. Learn some physics before posting your trash.
"I hate people who just run their mouth!" I do too , so shut your stupid piehole.
"Make me an affordable electric car smarty. " Make it yourself . BTW, cars are designed by engineers using PHYSICS, dumbass

Well, I just checked the quantization of the dirac field and the maxwell field in a book. It is quite a complex process, the math looks really ugly.I don't think this lecture can give you more than a vague idea how it works. Nevertheless, very interesting!

Finally, the dirac field is turned into an operator composed of creation and annihilation operators..... weird, weird,.... What about quantizing the electro-magnetic fields? Why does the dirac field need to be quantized at all?
bhigr 1 year ago
This is a weird application of classical lagrangians to the dirac equation. Somehow the terms of the equation are reinterpreted. The dirac spinors are interpreted as fields. These reinterpretations are probably the most difficult aspect for understanding.

I wonder why he is using the lagrangian formulation of classical mechanics instead of the hamiltonian....
bhigr 1 year ago
@bhigr Yeah, I'm kinda wondering the same thing, i guess we'll just have to transition to the hamiltonian in a higher level course

For the last one and a half years I have practically spent my free time watching and studying the series of lectures by Prof. Susskind. Thank you Stanford. I am greatful to you Leonardo.
