…and the fact that site works perfectly under load from being top of hn shows his skill with selecting and maintaining right kind of server setup.

I'd guess that most of the work is being done client side, leaving the server to just push out the text and code. I haven't tried to verify that assumtion though.

Earlier quoted context omitted.

I was able to reach 10^-7 mbar with a good vacuum system and I though I would have few thousand molecules, turns out there is a billion (10^9) molecules per cubic centimeter at that vacuum level.

And yet somehow, as far as we know, the energy of every molecular collision is faithfully preserved during a supernova, when effectively the entire volume of a star collapses into its core in less then a second. Reality is very strange.

That's not accurate. Only the inner core collapses (hence the "core-collapse supernova"; there are also other types), the rest rebounds, is heated up by core-produced neutrinos, and gets ejected. The Wikipedia article is a good start, also there are plenty of good papers on arxiv (e.g. on still-not-too-successful numerical modeling of the aforementioned "heating", without which the thing simply doesn't go bang).

I'm just as stunned as many others here after seeing this blog. What an incredibly talented engineer, writer, and artist all in one! He should be famous. Can't believe I hadn't heard of him.

If his site goes down, is the internet backing this up? Amazing work.

As a millenial with no degree+vague/little prospects of being able to one day purchase my own home, I've already saved his entire website and put it in my "very important things" folder.

As someone who really likes math, programming, and visual design as well as having spent hours upon hours practicing often short, yet incredibly complex lead guitar riffs by himself for many hours as a kid, I never quite grasped music theory back then and I realize now that essentially the only reason that is the case is because it was never presented to me in such a fun, digestible, and incredibly beautiful way; a way that I've been very much seeking to discover myself my whole life.

There are people who pay others to build schools, and then there are those that build things far more capable of transmitting the most optimally distilled form of knowledge and intellectual achievement that mankind has to offer to us today.

I don't really have much words right now, other than I want to kiss this man's feet and then maybe hope to stop crying eventually.

As an educational psychologist, there's a lot to love here and I catalog posts like these as examples of expert exposition. One suggest to Bartosz: breaking one long essay into many smaller pages or hiding content until the viewer has indicated understanding of previous steps will be even more useful (see: https://tigyog.app/d/H7XOvXvC_x/r/goedel-s-first-incompleten... ). Explorable models are a great way to increase…

Please no! Part of the beauty of this exposition is the respect for the reader knowing their own mind and controlling the consumption themselves.

You don't understand it but want to? Don't scroll. You don't want the next bit? Don't scroll.

Will this work for teachers in a classroom? Likely not as the kids who don't care, will skip everything they can. And this page will let them, because if you don't care to understand then this page is not for you.

This reminds me of spending hours digging through Microsoft Encarta as a kid. It was full of cool animations and demos like this (though these are much better).

This is absolutely phenomenal. This is how a lot of education should be. What blew my mind is how the author gradually increases the density of subject matter, going from the basics to the most advanced concepts in such a way that things just flow naturally. To say nothing of the interactive-ness of the page itself, which helps explain things exceptionally.

Superb post.
