Love the fact they haven't updated the website to more modern web technologies.

Do you love it purely for nostalgia? Because I loved this as much as you back in the day, but this website could definitely use some improvements to make it more accessible and palatable to students today.

I love it because it loads quickly and isn't more complicated then it needs to be.

In my case, there is a definite nostalgic bias. I would have used the site near the start of my university studies in 1996. That said, I think there is a case for leaving it as-is. Many sites are designed to be accessible and palatable to students today, so there is some merit to maintaining the original style in case it addresses the needs of people who are not well served by modern sensibilities.

Funny, I've been using the same sort of format for my own notes on physics [1]. Although in my graph there is no semantic meaning between graph nodes, maybe I should add that. 1: https://0x5.be/physics-notes/index.html

I really like that, especially the SVG diagrams. Is this exported from some flavor of TeX?

The page source is markdown, compiled to html with pandoc using mathjax.

There's some extra pandoc filtering magic to create hoverable equations.

The svg graphs are autogenerated from markdown links inside of the pages sources.

TIL about lua filters in pandoc 2+.

I saw that there's a diagram/graphvix thing in pandoc too - is pandoc doing the svg graphs, or something else doing the autogeneration?

A cyclic process is a thermodynamic process that eventually arrives back in its initial state: https://en.wikipedia.org/wiki/Thermodynamic_cycle

Thanks, had a read and I think I understand approximately. I am still wondering whether biological systems should count as cyclic in this sense too? I think that they seem to, in the returning-to-the-same-state thing, at least across the generations, and even in regular metabolism in some sense - but the law doesn't (intuitively) seem to apply in the biology/evolution case.. it doesn't just diffuse, it can go on in p…

I'd argue that using all those images and maps instead of svgs probably makes it load slower and is more complicated than it could be.

Why wouldn’t they be different than the initial conditions of the observable universe?

I wasn’t aware we are aware of those, either. In any case, the non-observable universe is certainly a superset of the observable universe.

We have some ideas... anyway, what do the initial conditions of our universe have to do with this one definition of the 2nd law?

The svg graphs are just generated from extracting markdown links. Right now it's a bash script that writes dot code to a file, and then the dot is compiled to svg... I really need to switch that bash script to jinja or anything a little more serious.
