Jet Manifestation: A World Unto Itself.

The Landscape Again and again....

***

(September 20, 2010) Leonard Susskind gives a lecture on the string theory and particle physics. He is a world renown theoretical physicist and uses graphs to help demonstrate the theories he is presenting.

String theory (with its close relative, M-theory) is the basis for the most ambitious theories of the physical world. It has profoundly influenced our understanding of gravity, cosmology, and particle physics. In this course we will develop the basic theoretical and mathematical ideas, including the string-theoretic origin of gravity, the theory of extra dimensions of space, the connection between strings and black holes, the "landscape" of string theory, and the holographic principle.

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

Quarks, gluons and anti-quarks are the constituents of protons, neutrons and (by definition) other hadrons.  It is a fascinating aspect of the physics of our world that when one of these particles is kicked out of the hadron that contains it, flying out with high motion-energy, it is never observed macroscopically. Instead, a high-energy quark (or gluon or anti-quark) is transformed into a spray of hadrons [particles made from quarks, antiquarks and gluons].  This spray is called a “jet.” [Note this statement applies to the five lighter flavors of quark, and not the top quark, which decays to a W particle and a bottom quark before a jet can form.] See: Jets: The Manifestation of Quarks and Gluons
