Just to ease the mental anguish inflicted by the "science of homeopathy" video, here's a fantastic musical mashup called "We Are All Connected" — not in any vague, New Age-y way, just by the fact that we're all made of "star stuff" forged in the explosions of supernovae, as Carl Sagan so eloquently put it when Cosmos first hit the airwaves. Sagan and Cosmos are sampled, naturally, along with Bill Nye the Science Guy, astrophysicst Neil de Grasse Tyson, the History Channel's Universe series, and a set of 1983 interviews with the late Richard Feynman. Get your physics groove on!
