Ok, so maybe I missed a few lectures in college. Perhaps quite a few.  But via deep web research, I’ve found an excellent deep web science lecture resource for high authority, peer reviewed, lectures covering science and technology.  Known at videolectures.net and provided free of charge to the public. The library contains 15,000 lectures of which 66% are in English. Provided to us for free courtesy of the Center for Knowledge Transfer subsidized by Slovenia. Hats off to those guys.
