|Welcome to the brand new Leader Talk section! Here I share with you some of the most profound talks from leaders in every field of the social and physical sciences. I may not agree fully with all of the talks I post! So my mission here is to present to you speakers who are funny as well as entertaining, who put forth ideas that you should at least find interesting, if not downright convincing on every occasion. Enjoy the most influential, intellectual, philosophical, entertaining, and relevant discussions that our planet needs to have right now. You’ll find my brief comments on each talk, and I encourage you to express your own viewpoints by posting a comment. Courtesy of ted.com, ideas worth spreading.
