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​​
