Since we discuss Quantum,Relativity, string theory, dark matter, and dark energy sometimes, I thought we’d better add a repository of videos, links, and pics.

Added 12/1/13:  Doc Physics discusses relativistic kinetic energy (13:13)

Added 11/26/13: Nobody does it better than Doc Physics. Here he summarizes a lot of relativity in less than 15 minutes.

Added 11/26/13: A good 10 minutes animation of light cones, time dilation, length contraction, Einstein and Lorentz.

Added 11/26/13:  Your Mass is NOT From the Higgs Boson by Veritasium
