This lecture contains awfully good explanations for the "running" of the different coupling constants :-)))
BTW, as Prof. Susskind explains in the first Lecture of the next to the following course, the force between a quark and an anti-quark is given by a Hook's law ... ;-). But writting more about it here could accidentally attract evil sourballs ;-P ...
At 1:27:00, he should have replaced e² by ħc, rather than 1, hence the confusion.
[The value of e is only "about a tenth" when ħ, c and 4πε₀ are all set to one.
Otherwise, e² ≈ 4πε₀ħc/137 (for large R). The 4πε₀ would cancel with the 1/4πε₀ that is normally in the Coulomb Law, and the 1/137 grows a little for very small R (but not by much), leaving a factor of ħc (and "about a a tenth" squared).]

Good, I like that you share this video, I wish success always Lecture 10 New Revolutions in Particle Physics: Standard Model

Thanks again very much for these Lectures :-)
It would be nicer to watch tha next SUSY course here in Youtube than with Itunes ...
But I will watch it anyway :-P ...

I love how he just erases stuff randomly and then says, "oh, I've lost it..." as if he wants to get the hell outta there

And thanks to Stanford and Leonard Susskind for these video's.

Thanks for uploading this. It's a pretty good intro by Susskind.
