Lecture 9 | New Revolutions in Particle Physics: Basic Concepts

(December 1, 2009) Leonard Susskind discusses the equations of motion of fields containing particles and quantum field theory, and shows how basic processes are coded by a Lagrangian.

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.

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

Great video. Please upload more. Thanks!

@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

@KKZZII grateful* sorry I just had to say that.

fantastic series

Mr. Susskind

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?
