Leonard Susskind (Stanford): Quantum Entanglements, Part I; Lectures 1-9

From Wikipedia:
Leonard Susskind (born 1940) is the Felix Bloch Professor of Theoretical Physics at Stanford University. His research interests include string theory, quantum field theory, quantum statistical mechanics and quantum cosmology. He is a member of the National Academy of Sciences, and the American Academy of Arts and Sciences, an associate member of the faculty of Canada's Perimeter Institute for Theoretical Physics, and a distinguished professor of the Korea Institute for Advanced Study. Susskind is widely regarded as one of the fathers of string theory, having, with Yoichiro Nambu and Holger Bech Nielsen, independently introduced the idea that particles could in fact be states of excitation of a relativistic string. He was the first to introduce the idea of the string theory landscape in 2003. In 1997, Susskind was awarded the J.J. Sakurai Prize for his "pioneering contributions to hadronic string models, lattice gauge theories, quantum chromodynamics, and dynamical symmetry breaking." Susskind's hallmark, according to colleagues, has been the application of "brilliant imagination and originality to the theoretical study of the nature of the elementary particles and forces that make up the physical world."

The Double Slit Experiment

The Double Slit Experiment:

From Wikipedia: (http://en.wikipedia.org/wiki/Double-slit_experiment)
"The double-slit experiment, sometimes called Young's experiment, is a demonstration that matter and energy can display characteristics of both waves and particles. In the basic version of the experiment, a coherent light source such as a laser beam illuminates a thin plate pierced by two parallel slits, and the light passing through the slits is observed on a screen behind the plate. The wave nature of light causes the light waves passing through the two slits to interfere, producing bright and dark bands on the screen — a result that would not be expected if light consisted strictly of particles. However, at the screen, the light is always found to be absorbed as though it were composed of discrete particles or photons.  This establishes the principle known as wave–particle duality."



Professor Jim Al-Khalili: The Atom (Video)

In this three-part documentary series, Professor Jim Al-Khalili tells the story of one of the greatest scientific discoveries ever: that the material world is made up of atoms.

First episode deals with the discovery of atoms and its impact on the scientific community, it also tackles the quantum mechanics of Heisenberg, and the problems Einstein had it with it.

The next episode deals in the radioactivity, atom bomb and the big bang.
Finally, the last episode questions the nature of reality. How the composition of the atom made us rethink physical existence, giving a possibility to parallel universes and showing that empty space is far from empty.      Videos:  Professor Jim Al-Khalili: The Atom (Part I-III)
