Most are about five minutes (some longer, some shorter) and cover topics like chemistry, physics, calculus, geometry, biology, Algebra, trigonometry, grammar, ACT prep, and SAT prep. ” Kudos to their ability to achieve that goal. C-Span Classroom is free but requires registration to access materials. Futures Channel.

And indeed particularly in chemistry and engineering it’s often been in the background, justifying all the computations routinely done using entropy. But, first and foremost, the story of the Second Law is the story of a great intellectual achievement of the mid-19th century. But first we have to go back a bit in the story.

It didn’t help that his knowledge of physics was at best spotty (and, for example, I don’t think he ever really learned calculus). In 2015 Ed told me a nice story about his time at Caltech: In 1952–53, I was a student in Linus Pauling’s class where he lectured Freshman Chemistry at Caltech.

But there’s really just one principle that governs all these things: that whatever method we have to prepare or analyze states of a system is somehow computationally bounded. We’ve been talking about a demon that’s trying to “achieve something fairly simple”, like maintaining a barrier or a “one-way membrane”. How do we achieve this?

Part of what this achieves is to generalize beyond traditional mathematics the kind of constructs that can appear in models. Chemistry / Molecular Biology. In standard chemistry, one typically characterizes the state of a chemical system at a particular time in terms of the concentrations of different chemical species.
