Taking that internship in a remote mountain lab might not have been the best idea. Pulling that lever with the skull symbol just to see what it did probably wasn’t so smart either. But now is not the time for regrets because you need to get away from these mutant zombies...fast. Can you use math to get you and your friends over the bridge before the zombies arrive? Alex Gendler shows how.

The Theoretical Minimum: Quantum Mechanics 2012 (Leonard Susskind / Stanford U)

# automatic playing for the 10 videos (click the up-left corner for the list)

source:  Stanford     Last updated on 2014年9月25日
This course is comprised of a six-quarter sequence of classes that will explore the essential theoretical foundations of modern physics. The topics covered in this course sequence will include classical mechanics, quantum mechanics, the general and special theories of relativity, electromagnetism, cosmology, and black holes. While these courses will build upon one another, each course also stands on its own, and both individually and collectively they will let students attain the "theoretical minimum" for thinking intelligently about modern physics.

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 Schroedinger. 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 Schroedinger Equation.
