In these lectures Michael Faraday’s careful examination of a burning candle reveals the fundamental concepts of chemistry, while at the same time superbly demonstrating the scientific method. In this lecture Faraday reveals why a candle’s flame is bright. To do this he investigates the properties of the flame.

This book introduces modern readers to Michael Faraday’s great nineteenth-century lectures on The Chemical History of a Candle. This companion to the RUclips series contains supplemental material to help readers appreciate Faraday’s key insight that “there is no more open door by which you can enter into the study of science than by considering the physical phenomena of a candle.” Through a careful examination of a burning candle, Faraday’s lectures introduce readers to the concepts of mass, density, heat conduction, capillary action, and convection currents. They demonstrate the difference between chemical and physical processes, such as melting, vaporization, incandescence, and all types of combustion. And the lectures reveal the properties of hydrogen, oxygen, nitrogen, and carbon dioxide, including their relative masses and the makeup of the atmosphere. The lectures wrap up with a grand, and startling, analogy: by understanding the chemical behavior of a candle the reader can grasp the basics of respiration. To help readers understand Faraday’s key points this book has an “Essential Background” section that explains in modern terms how a candle works, introductory guides for each lecture written in contemporary language, and seven student activities with teaching guides.

I don't feel that the lycopodium or the sulfuric acid demonstrations were particularly redundant and I'm glad it was decided to include them in the video. Attention was drawn to the sound that the powder makes to show that the combustion is not happening all at once. The sulfuric acid gives an example of a flame that arises from a mixture of several room temperature chemicals. In the case of candles and all other combustion up to that point, they were started from another flame using direct heat. The theatrical nature of the demonstrations is a bonus.
6:30 It should always be described this way around, Faraday had it right. Explaining it this way mimics the actual process of asking questions and trying to discover the answer. It's much better at conveying the scientific method, rather than getting the answer first and then having it explained. I mean if you have the answer already, why care about the process of finding out how you got the answer? You don't need the process anymore, you have the damn answer!
I find it oddly disconcerting that they talk about Faraday like they're watching his lecture, but the video shows Bill acting it out.
It would really be great to have a video of Faraday himself, but RUclips isn't (yet) a time machine.
6:12 watched this in Chem class the other day and couldn’t stop laughing. Looks the the guy from trailer park boys
7:20 Gunpowder is not in a reaction of oxygen, gunpowder itself is a mixture of fuel and oxidizer.
Nice
first like again XD

"Watch how we see faraday" lol why cant they just say in faradays teachings or faradays experiments shows this. When bill is looking at himself call himself faraday is weird and distracting.
