Lecture 5 | New Revolutions in Particle Physics: Basic Concepts

(November 2, 2009) Leonard Susskind gives the fifth 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, more specifically, energy conservation, waves and fermions.

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.

I have seen so many of these lectures that I even understand this now. beyond my wildest dreams.

Professor Susskind, If you ever come to London, I do not have much, but you have a room and free beer in any pub you should ever with to visit, I shall introduce you to the best. there is no way I can ever thank you enough,

WOW, he lost so much weight

I Love The Video It Can Increase My Knowledge In this lecture he continues on the subject of quantum field theory, more specifically, energy conservation, waves and fermions.

Good, I like that you share this video, I wish success always 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

Your Video Is Very Useful Sharing Leonard Susskind gives the fifth lecture of a three-quarter sequence of courses that will explore the new revolutions in particle physics.

I have been through so many seminars about science. But, honestly speaking, this one is pretty complex.

Actually, the neutrino is fermionic and it is a lepton. Not bosonic.

@bhigr Phase and group velocity are the same only in vacuum, not in a medium.

[bhigr]

The quantum mechanical state is defined by the maximum number of commuting observables. If you know them, then you have completely characterized the state. Two fermions may not have the same Eigenvalues for each of its commuting observables. Then it would be in the same "state".

[bhigr]

If the phase velocity of a photon were always the same as its group velocity, then dispersion for light waves would not exist. This is not true. Something is fishy.
