Hackaday (July 3) -- “There is no better, no more open door by which you can enter into the study of science than by considering the physical phenomena of a candle,” said British chemist Michael Faraday in 1848. Even now, over 150 years later, one would be hard pressed to find an object of study that would equal the candle, said Bill Hammack and Don DeCoste in their new companion book to the YouTube series on The Chemical History of a Candle.
