Derek Muller and his YT channel Veritasium should be part of any bookmark collection (no matter how anachronistic that may be…).

Derek's approach to getting to the root of physics and math problems is why his documentaries are purchased and broadcasted by major TV channel players.

A few weeks ago, Derek touched upon our thematic world again: Why The First Computers Were Made Out Of Light Bulbs is all about just that – the relationship between computers and light bulbs.

Sounds strange at first? Apart from the fact that that's certainly intentional, the video is, as always, informative and of exemplary quality. If you don't know Derek: It's time.
