Lecture 6 | New Revolutions in Particle Physics: Basic Concepts

(November 9, 2009) Leonard Susskind gives the sixth lecture of a three-quarter sequence of courses that will explore the new revolutions in particle physics. In this lecture he continues on the subject of quantum field theory, including, the diary equation and Higgs Particles.

Leonard Susskind, Felix Bloch Professor of Physics, received a PhD from Cornell University and has taught at Stanford since 1979. He has won both the Pregel Award from the New York Academy of Science and the J.J. Sakurai Prize in theoretical particle physics. He is also a member of the National Academy of Sciences.

Good, I like that you share this video, I wish success always In this lecture he continues on the subject of quantum field theory, including, the diary equation and Higgs Particles.

my reaction to this is that, it really derives the new components of physics, apart from what Einstein had developed.

Your reaction? I want my mommy.

At 0:24:20, how come d(psi)/d(x) equal to ik?

[wizardofmadness]

0:00:15 - Alright!

[purpleproductionftw]

is it just me, or does Susskind looks weird skinny?

This video is very unstable in China. ><

Another intuitive way to derive the decoupled equations is to start from

w^2 = k^2 +m^2

and see that w^2 is obtained by minus the second time derivative, k^2 is minus the second time space derivative and m^2 is simply obtained by multiplying the undifferentiated field by m^2: hence

d^2/dt^2 Psi - d^2/dx^2 Psi = m^2 Psi

both left and right field satisfy this...

Of course the method followed by Prof. Susskind is more relevant because it works in the non-linear case... ahem :P
