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 focuses on the physical changes occurring in the candle, for example, how the wax moves from the candle into 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 RU-vid 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.

These videos feel like something you'd purchase for $50. They are so well made and carefully crafted with all the detail and extras like commentarys or edits, yet offered for free without cutting any content. And all I can do is buy the books/become an advanced viewer and say thank you for putting so much effort into this. Seriously, thank you.

@4.0.4 8 лет назад

I'm not a native speaker, and I must say, the language here is lovely! This is the English everyone should still be using, it shines with passion as well as intellect! It was also more than just understandable, it communicated things on a deeper level, reminded me of how Feynman was good with words.

@4.0.4 8 лет назад

(I know this was Faraday, what I meant is him and Feynman seem to have both been just as good in didactics)

@fmlAllthetime 8 лет назад

The vast majority of people never spoke like this and never will. There is still amazing speakers out there, they're just rare, hence the respect they're given.

@4.0.4 8 лет назад

+fmlAllthetime I know, but even educational material, speeches, youtubers, and more (people who usually did write down some script) speak in not just simplistic, but conversational English, to the point where finding something like this is rare. It seems to have been more common up to some point in the last century, maybe the youth of baby boomers?

@RobertMoser 7 лет назад

It takes a powerful mind to condense truth into the fluid path of speech. And I agree with you; the words of Faraday have a mellifluous tone of rare and special quality. We can but aspire.

@ryedj707 5 лет назад

It’s definitely smart and compelling speech. I feel sometimes though, faraday really repeats words a little too much in certain instances, and thus goes overboard.

@natalieobman5018 6 лет назад

Small complaint, but the original chemical history of a candle has an examination of 19th century candle making. I suppose it makes sense to remove it since few can claim to be friends with the town chandler, but some important connecting factors are also removed. For example, establishing or most likely re-establishing that the candle wick is cloth helped bring home the universality of physics during the towel demonstration. The capillary action of a candle is the same as the action of a towel, which is the same as when water moves up the skin when handwashing. This is part of why these lectures are so amazing. "Gravity holds worlds together and the fluid in a candle horizontal" is a good complete example. It shows the audience all things operate under the same set of laws, and subtly encourages listeners from then on to see the world differently. Still, these videos are absolutely amazing.

@Maltanx 8 лет назад

I have really no words to express how much i love this video, it just makes me want to know a lot more. Who could ever immagine that what seems to be an insignificant object such a candle could hide so much beauty? I'm really thankful for your great work, video like this just show how beautiful is the world. Thank you again, your work is very remarkable, i will never thank you enough for the passion and love you put in your videos

@DylanODonnell 8 лет назад

I think the language is a bit fast, but indeed charming and agree with it's preservation! This is the best thing to hit my youtube feed in ages, thank you.

@engineerguyvideo 8 лет назад

It is Faraday's 19th century language: we thought of changing it, but then you use some of the "charm" or "essence" for faraday. So, instead we added subtitle, did a commentary version, and wrote a book to have viewers ....

@DylanODonnell 8 лет назад

Agree completely .. it's a really compelling prose around the scientific exegesis and I think it works perfectly. Great job Bill!

@kurtjohnson6464 8 лет назад

I have watched many of your videos and if you take the kind of passion you show in your videos into the classroom.... WOW ! I want to be a student ! I can see why you love Faraday's lecture and I think that you brought it to modern terms just enough to understand but not so much as to loose the the feel of Faraday. Mastering the compromise nicely! Excellent!!!

@talonfortytwo2719 8 лет назад

It certainly must have been ignorance that compelled the few people to dislike this video. You do such great work on this channel. Now I have to go and watch all of the other lectures. I love this channel.

Truly inspirational!! Watching this gave me for a moment the feeling that I was part of the audience of Faraday himself!! Thank you for the quality of education your channel provides.

@jacobhempel1855 Год назад

Lots of hard work put into this magnificent video. I really love that they stuck with the poetic language from Faraday’s actual lecture, even if it makes content a bit more cryptic. It felt like I was transferred back in time to watch a lecture given by one of my favorite scientists. Thanks for this experience!

@EyeLean5280 Год назад

This is so beautifully written, like poetry! I'm always sad when I hear people say they don't like 19th century writing, that they find the language too hard. I even heard this once from a librarian! Strange how middle schoolers were once able to follow such prose but we assume we're too far removed from it and don't take the (actually rather small) effort to follow along with it.

"these good looking candles are bad burning ones." *proceeds to show the most ugly candles I have ever seen*

@jlapham 3 года назад

These lectures are originally from the 1800's. They updated the terminology, but kept as close to them as they could, while still being comprehensible to most people of today. The 'good looking candles' part was a tongue-in-cheek joke.

@medimagery. 3 года назад

Yes. But the flame is most of the beauty anyway. So you cannot take away from that.

@danieldonkersloot3565 8 лет назад

I'm personally very grateful to be able to step back in time and hear Faraday himself. While the language is of course not exactly what we are used to, it isn't pretentious or needlessly fluffy. It flows like poetry, all while describing the various phenomenon with a kind of contagious enthusiasm through his carefully chosen words.

@karinasharpe4754 4 года назад

6:52 I acctually never knew how it could work like that and I was always confused seeing people do it, but the explanation made it so much clearer for me to understand. It's like an invisible candle wix that connects to the acctual wix. And I also never knew there would be such a relationship between airflow and the way a candle lights. I always thought the puddle of melted wax was there because that's where the flame was, not because of the air flow.

@jiyeongkim3760 4 года назад

1:26 before I watched this video, I did not know why the edge of candle much cooler than the part within, but through this video I realized that as the air comes moves upwards by the force of current which the heat of the candle produces, and it so cools all the sides of the wax, as to keep the edge much cooler than the part within. I learned a lot about candles through your video, thank you for make this video!

Any should do. We used wide candle because we shoot with a 16:9 frame and a regular candle is too narrow -- it disappears in the frame. Video is licensed Creative Commons so your students can download, reversion etc.
