Lecture 7 | New Revolutions in Particle Physics: Standard Model

(February 22, 2010) Professor Leonard Susskind discusses spontaneous symmetry breaking and gauge invariance.

This course is a continuation of the Fall quarter on particle physics. The material will focus on the Standard Model of particle physics, especially quantum chromodynamics (the theory of quarks) and the electroweak theory based on the existence of the Higgs boson. We will also explore the inadequacies of the Standard Model and why theorists are led to go beyond it.

This course was originally presented in Stanford's Continuing Studies program.

Good, I like that you share this video, I wish success always Professor Leonard Susskind discusses spontaneous symmetry breaking and gauge invariance.

Prof.Susskind is what can be considered "The Professor".

In its lecture, he gives the core of theory. Details can be read and learn by a book.

great professor.

Iám starting to be a Susskind advocate. Hahaha

[DaMadFish]

Great explanations, I love your lectures!

Hey people,

just be a bit more patient.

I think Prof. Susskind just wants to lay out and explain some important concepts here, which he does quite well as usual. Didnt he promise to clear things up and put it all togehter in the next lecture?

Parallel-reading a book can help too ... "Quantum Field Theory Demystified" is easy to read and very accesible. It gives very clear explanations of the important concepts discussed in this and the previous course. The only thing left out is QCD.

Cheers

Just to be clear, again, I'm know he's a great physicist, it's his teaching. My issue isn't a lack of understanding, I am pretty much on top of everything he is talking about. My issue is that he doesn't flow well from topic to topic, hesitates, etc... My goal isn't to slam the man uncompromisingly, just saying I am frustrated.

[Sivring]

this course is a non physical review in all possible ways, as it should be. Just as good, as possible.

First off, THANK YOU Prof. Susskind for taking the time to let thousands of us to hear your beautiful insights who otherwise would never have the chance to benefit.

Next, to the criticism below, lecturing about a complex issue is similar to (but much more difficult) performing a complicated dance routine. You try to sort out the best route from a zillion ways to move through a maze of logical and empirical facts so to minimize the effort for the listener. Only a master can do it.

@jsmall10671 I agree, partly. His other courses (Classical Mech, Stat Mech, General Relativity) are excellent: far clearer and far more rigorous. But he's trying to get through too much material in this one - a self-contained course on QFT and the standard model in a few weeks isn't feasible, so he's ended up talking around things instead of working through them.

If he'd insisted on the other lectures as strict prerequisites and set off from that understanding, it could have been much clearer.
