Pat isn't registered on Discourse yet, but recommended this video of a lecture he saw on 21st Feb: https://tv.theiet.org/?videoid=11575
He's not sure how long it will remain available, so watch while you can . . ..
Pat says: "The main talk starts at about 18 minutes 45 seconds. The theme of the lecture is whether innovation is driven by science or by art (or some balance of the two). Very interesting and very Bridge Rectifier."
