Lecture 9 | New Revolutions in Particle Physics: Standard Model

(March 30, 2009) Leonard Susskind explains how the Higgs phenomenon interacts masses of quarks and leptons.

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.

great models.

I commend this professor for his excellent discussions.

@csmcmillion

Oh yes You are right, I mean cookies of course ;-)

(sometimes my English skills leave me alone, ha ha ...)

[astrobassist]

wow this is such an amazing lecture...just what I needed...Higgs mechanism and the nature of mass...with enough math to show what the guts look like without getting his hands dirty...what a brilliant lecturer and I love the questions and answers

[csmcmillion]

@Dilaton100 cockies? I don't think Leonardo swings that way.

[LolIGuess123]

LOL. Just like grad classes. 1st Lecture has many views, and by the 10th lecture the number is reduced to about 1/3.

@keggerous

Most physicists don't care for philosophy.

You know his lectures are such that you don't have to be a specialist to watch even though the are very technical

[Dilaton100]

Poor dear Prof. Susskind,

he looks so tired at the end of the lecture. He needs more coffee and cockies; he really deserves it giving such good lectures after maybe a long day of teaching other classes ... :-)

How does one compute the value of f ?

If a neutrino has mass and so does not move at the speed of light, then we can catch up with it and observe its spin in the opposite direction?

If energies were largest at the time of the big bang, would this have been a time when these large mass particles would be created (the ones whose mass does not result from symmetry breaking)? Is this when dark matter was formed?
