The Chemical History of a Candle

While we are at it, the Engineering Guy has a really good youtube channel. His videos are not very frequent most of them does a great job explaining how mundane objects are designed and manufactured. I thought I was familiar with some of his subjects but I always end up learning something new after watching.

Personal favourites:

I read a fascinating new biography of Faraday recently. I didnt know he did a lot in chemistry also, like these lectures.

We are approaching the 200th anniversary of his invention of the continuous electric motor in 1821. We have a specific origin-story in his notebooks as how he presented it as a novelty to nephew.

Gotta take a sec to recommend his book Why Engineers Need to Grow a Long Tail. It's an unusual and inspiring book.
