Fascinating! As a behavioral neuroscientist, I would like to warmly thank Pr Susskind for providing - at last - the non-physicists with a serious glimpse at what quantum mechanics is all about. I feel that everyone deserves to have access to the theoretical rudiments of quantum mechanics. We are much too big to directly experience the quantum world! It is thus a unique human experience to see how we, humans, have been progressively able to build a powerful mathematical framework that helps us to overcome our inherent physical infirmity and successfully jump over the quantum gap.
