1:48 SW starts talking and begins his presentation
2:04-21:44 History of Sadi Carnot and Réflexions sur la puissance motrice du feu (Part 1), featuring Lord Kelvin and the 2nd Law of Thermodynamics
21:44-33:50 SW reads passages from Réflexions sur la puissance motrice du feu (English translation)
33:50-37:58 SW shares the book on-screen (original French version)
37:58-57:50 History of Sadi Carnot and Réflexions sur la puissance motrice du feu (Part 2), featuring Lazare Carnot and Napoleon
57:50-1:51:40 SW reads more passages from Réflexions sur la puissance motrice du feu, including biographical excerpts + unpublished writings of Sadi Carnot
1:51:40-2:04:20 History of Sadi Carnot and Réflexions sur la puissance motrice du feu (Part 3), featuring the impacts of Carnot's work on future research into thermodynamics
2:04:20-2:06:02: SW concludes his presentation
2:06:12 Q&A begins
2:06:33-2:06:51 Ah, so Carnot was the original 'new kind of science' guy of his time.
2:07:02-2:07:28 If you think about it, we mostly still life in the steam ages. Most of the energy we get is steam at one point.
2:07:29-2:08:05 Why was Carnot's printed with such wasteful borders and only few lines per page?
2:08:08-2:10:19 What does it mean to discuss the "heat death of the universe" if entropy law only pertains to a closed system? Is this still plausible according to current physics?
2:10:27-2:11:48 Are there ways to measure the efficiency of a stochastic system using principles derived from Carnot's work on heat engines?
2:11:49-2:12:03 Heat-Engines were the AI of those times!
2:12:37-02:15:27 How did scientists deem 'dark matter' to be a real thing?
2:15:31-02:24:18 Has anyone ever done further investigation into the paper you wrote with Jan Ambjorn on the thermodynamics of the vacuum?
2:24:37-02:27:10 Is there any link between Carnot's findings and modern information theory?
2:27:15-02:27:46 SW's closing thoughts

00:00 Start stream
00:46 SW starts talking
00:59-22:52 How rare was the recent New Jersey earthquake? How can we predict future earthquakes?
22:55-23:17 The Indian Plate is moving very fast. Its increasing the height of Mt. Everest by six centimeters every year.
23:20-25:29 I wonder if digging for oil and fracking, etc., have any effect on the plates?
25:29-32:07 How do earthquakes cause tsunamis?
32:24-33:16 It seems like studying underwater earthquakes vs. those on land might be a good way to investigate the lubrication effect.
33:21-34:00 Solitary waves were discovered by the naval architect John Scott Russell in 1834.
34:30-36:36 Anything particularly interesting or surprising from the solar eclipse? It appeared that leading up to it, between the book and website, it was better understood than any previous solar eclipse before it happened. Now that it has happened, what interesting findings have there been, if any?
36:39-55:23 What causes Earth to have different biomes?
55:29-59:29 Why is there only one species of human? What happened to Neanderthals?
59:44-1:07:50 How do astronomers determine the composition of planets and stars that are light years away from us?
