Quantum Mechanics

Quantum Mechanics (Winter 2008, Standard Univ.). Instructor: Professor Leonard Susskind. Quantum theory governs the universe at its most basic level. In the first half of the 20th century physics was turned on its head by the radical discoveries of Max Planck, Albert Einstein, Niels Bohr, Werner Heisenberg, and Erwin Schrodinger. An entire new logical and mathematical foundation - quantum mechanics - eventually replaced classical physics. We will explore the quantum world, including the particle theory of light, the Heisenberg Uncertainty Principle, and the Schrodinger Equation. (from
