I found the previous Hamiltonian Neural Networks [0]. If the authors are here, I'd be interested to use [1] for a version with dissipation. [0] https://greydanus.github.io/2019/05/15/hamiltonian-nns/

Yes, like linux liberated the pc from windows. Now is much more complicated, because a liberated harware is needed as well. Sigh, this is too much, but at least as you say: a normal computer in the smartphone form factor, where I can instal

I upvoted this, but it is not accurate. If you're French then you may be misled by the combination of two signals: "Ecole Polytechnique (X)" (aka "social status") and birth date (aka "old"). This gives &qu

Oh sweet memories. I was born in 1967, so I'm older than the author, but the memories are somehow the same. I started with a Sinclair ZX Spectrum clone, called HC85, and with Basic as first language. I discovered the Mosaic browser in

Same here. This "it was a dark and stormy night" style is bad writing. I read a lot, I like reading novels. This is just an empty structure. In this particular case the bad writing almost killed an interesting subject.

I don't quite understand this conflation of mathematics with category theory. This obsession of some programmers with mathematics, actually with a tiny part which is category theory, looks to me very strange. By chance, there is this r

A scenario more interesting than boundless self-replication is Ackermann goo [0], [1]. Grey goo starts with a molecular machine able to replicate itself. You get exponentially more copies, hence goo. Imagine that we could build molecules l

Some numbers: There are 264 posts with animations, a bit more than 1/2 of the original collection, with the possibility to rerun in js the simulations. Whenever possible there is a mol file attached to the animation. There are about

There's a great book by Truesdell, named "An Idiot's Fugitive Essays on Science". According to Truesdell, the initial meaning of the word "idiot" was one who does not have preconceived ideas. https:/&#x2F

If you're into lambda calculus or artificial life, then here is a landing page I made for several of my (and contributors) projects. You have here a lambda calculus parser and graphic rewrites reducer, a collection of artificial life a

Some trivial mathematical facts. No matter what algorithm you use, you want to make a quasiisometrical embedding of a tree into a finite dimensional space. Or, for a tree the no of nodes at distance R from the root is like exp R, but in any

I don't get it, is "classic" bad? My page is online since 1995 and is still the best way I share my work. There surely are many "classic" style sites, with unique information. I'd encourage everybody who has so

I second this. Conserved quantities (by extension symmetries) do not compute. Car engines and refrigerators are both thermal engines, but the same conserved quantities are engineered (say programmed) to do different things.

I'm interested to know more about it, especially if it can be used for Open Science. As a researcher, I look for the less bloated way to replace a scientific article with a corpus of work which can be independently used by other resear

Paris is a big city, that's all. The Eiffel Tower and Moulin Rouge are not among the most interesting things to see in Paris. People are not like in a Disney movie.
