Nobel Prize winner and owner of the best accent in science, Wolfgang Ketterle is one of the foremost researchers into one of the most intriguing areas of Physics – the study of matter at ultra cold temperatures.
In particular the Bose-Einstein condensate, where quantum effects like the wave nature of matter can actually be seen at the macroscopic scale with atoms “walking in lockstep” together.
Here is one of his great lectures from MIT on Bose-Einstein Condensates: The Coldest Matter in the Universe. Not exactly ‘general interest’ viewing, but enlightening if you can keep up.
