## Detailed walkthrough ### [00:02](https://www.youtube.com/watch?v=RrHnLXMTOWM&t=2s) Introduction to Michael Faraday's Lecture Series

Bill Hammack introduces a five-video series presenting Michael Faraday’s renowned nineteenth-century lecture series, *The Chemical History of a Candle*. Even after 150 years, the ordinary candle remains an unsurpassed pedagogical tool for exploring the natural world. By carefully dissecting and observing a burning candle, Faraday lays bare core physical concepts—such as mass, density, heat conduction, capillary action, and convection currents—alongside the critical distinctions between physical and chemical changes. Throughout the course of the lectures, Faraday also illuminates the nature and behavior of gases including hydrogen, oxygen, nitrogen, and carbon dioxide, culminating in an extraordinary final lecture where he draws a direct analogy between combustion in a candle flame and human respiration.

```mermaid flowchart TD accTitle: Core Concepts in The Chemical History of a Candle accDescr: A diagram showing how Faraday uses the study of a candle to explain fundamental physical and chemical principles leading up to human respiration. subgraph CandlePhenomena["The Burning Candle"] A["Candle Study"] end subgraph PhysicsChem["Fundamental Science"] B["Physical Concepts<br>(Mass, Density, Capillary Action, Convection)"] C["Chemical Concepts<br>(Gases: H2, O2, N2, CO2 & Phase Changes)"] end subgraph Climax["Final Synthesis"] D["Human Respiration"] end A --> B A --> C B --> D C --> D ```

In adapting these classic presentations for video, Hammack and his team strove to retain Faraday’s original language as much as possible, drawn to its eloquence and charm. Modifications were made sparingly: terminology was updated to modern scientific usage (particularly chemical names), and certain historic demonstrations were substituted with modern or safer equivalents. As Hammack highlights Faraday's philosophy regarding the accessibility of science through everyday objects:

> “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.”

- Concepts covered: mass, density, heat conduction, capillary action, and convection currents. - Chemical processes explored: phase changes, chemical versus physical properties, and the characteristics of hydrogen, oxygen, nitrogen, and carbon dioxide. - Modern adaptations: updated chemical terminology and the implementation of safer demonstration protocols.

Recognizing that nineteenth-century lectures can still present hurdles for contemporary audiences, Hammack and his collaborators implemented three specific resources to aid comprehension. First, they produced an alternate version of every lecture featuring a dedicated commentary track, where Hammack and co-creator Don DeCoste guide viewers and explain the principles behind Faraday’s demonstrations. Second, closed captioning was added across all videos, including the commentary editions. Third, they authored a comprehensive companion book available as a free PDF download.

The companion volume incorporates complete verbatim transcripts of the lectures as delivered in the video series. To ground modern audiences, it includes an "Essential Background" chapter explaining the mechanics of candle combustion using contemporary science, along with chronological lecture guides designed to be read alongside the videos. Because Faraday originally developed these talks for newcomers and young people, the book also features an extensive teaching guide aimed at educators. This pedagogical section includes "The Big Ideas of Chemistry"—which uses simple analogies to explain the particulate nature of matter—as well as six student activities and a suite of demonstrations complete with printable worksheets and teacher answer keys. Hammack concludes by noting that the companion book is also available for purchase in ebook, paperback, and hardcover formats, acknowledging that this project was truly a labor of love for himself, Don DeCoste, and Alex Black.

> “Faraday aimed his lectures toward those new to science, especially young people.”

This book introduces modern readers to Michael Faraday’s great nineteenth-century lectures on The Chemical History of a Candle. This companion to the YouTube 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.

This companion to the YouTube 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. Author Bios Bill Hammack is a Professor of Chemical & Biomolecular Engineering at the University of Illinois—Urbana, where he focuses on educating the public about engineering and science.

Original transcript

[0:02] In five videos I share with you Michael Faraday’s great nineteenth lecture series “The Chemical [0:07] History of a Candle.” Faraday said of a candle: “There is no more open door by which [0:12] you can enter into the study of science than by considering the physical phenomena of a [0:16] candle.” Even now, 150 years after Faraday delivered his lectures, one would be hard [0:22] pressed to find an object of study that would equal a candle. Through a careful examination [0:27] of a burning candle, Faraday reveals the concepts of mass, density, heat conduction, capillary [0:32] action, and convection currents. He demonstrates the difference between chemical and physical [0:37] processes. He reveals the properties of hydrogen, oxygen, nitrogen, and carbon dioxide. And, [0:44] in a stunning final lecture, he uses a candle to explain human respiration. In creating [0:50] these video we used Faraday’s original language because his poetic turns of phrases charmed [0:55] us. We changed his words only when necessary. We updated terminology, especially chemical [1:00] terms and we replaced some demonstrations with modern or safer ones. Even with these [1:05] changes the lectures can be a challenge for the modern viewer and so to help today’s [1:10] viewers appreciate the lectures my co-creators and I have done three things. First, we created [1:15] an alternate version of each lecture that has a commentary track. In the commentary [1:21] my co-creator, Don DeCoste, and I guide viewers through the lectures highlighting the concepts [1:25] underlying Faraday’s demonstrations. And, second, we added captions to all the videos, [1:31] including the commentary versions. And third, we wrote a companion book for this video series [1:37] that is available as a PDF for free. The book contains the complete transcript of each lecture [1:43] as delivered in the video series. To help you grasp Faraday’s key points it has an [1:47] “Essential Background” section that explains in modern terms how a candle works. And, each [1:53] lecture is preceded by a short guide written in contemporary language. These guides mirror [1:58] the lectures chronologically so you can follow while watching the lectures. In addition the [2:03] book has a detailed teaching guide. Faraday aimed his lectures toward those new to science, [2:09] especially young people. His lectures remain today an excellent introduction to the scientific [2:14] method and serve well as an entry point to the chemical sciences. The teaching guide [2:19] contains a section called "The Big Ideas of Chemistry,” which uses simple analogies [2:24] to introduce younger students to the particulate nature of matter. Following this, the guide [2:28] contains six activities and one set of demonstrations that teachers can use to help students investigate [2:34] for themselves “the chemical history of a candle.” Each activity has a student worksheet [2:40] followed by a teacher’s guide. Teachers can use these guides and student worksheets [2:44] for free. We give you the complete book free as a PDF — you can download the book at [2:50] engineerguy.com/faraday — or you can buy it as an ebook, in paperback or hardcover. [2:56] So, I hope you enjoy the lectures. For me and my co-creators, Don DeCoste and Alex Black [3:02] they were a labor of love. I’m Bill Hammack, the engineer guy.
