Ever heard of these or seen some already? “TED is a nonprofit organisation devoted to spreading ideas, usually in the form of short, powerful talks (18 minutes or less). TED began in 1984 as a conference where Technology, Entertainment and Design converged, and today covers almost all topics — from science to business to global issues — in more than 100 languages”. These are really worth a look, not to say several. The speakers are not only leading authorities in their fields but great speakers. 1900 + titles cover a huge range of topics which you can look at individually but are also gathered into playlists around linked topics. If you happen to have Netflix you see lots there to. Radio 4 Extra have also been linking up with TED talks.
