Following a long personal tradition, December is the month that I re-read Michael Faraday's marvelous Chemical History of a Candle. This is a written version of his famous Christmas lectures for children, and his style and ease at explaining complex science to children always delights me. He presented other Christmas lectures, and they are all marvelous, but the Chemical History of a Candle series remains my favorite. You can read it online for free here: http://www.gutenberg.org/ebooks/14474
In honor of Mr. Faraday, here are some of my videos that involve candles. They are free for the month of December.
