Cloning the jekyll example repo on github then writing some markdown is not a large technology detour. Although I personally prefer hugo on gitlab.

That's interesting, coming from the Lean language the analogous function - rw, or rewrite - is a real workhorse. It's often very useful to manipulate expressions when proving things. Why do you think it's a code smell?

Well, I did it. I wrote an extended dialogue explaining the replace function as a blog post: https://ahelwer.ca/post/2022-10-13-little-typer-ch9/ I'd found your review a week or so ago which was nice since it

I personally found this chapter very confusing, even with a good working knowledge of quantum computing - specifically the part about paths interfering destructively and canceling each other out. After a lot of thought and asking around I f

I've been reading through this and greatly enjoy it - up until chapter 9, which is like a giant boulder that tumbled to block a nice hiking trail. The definition of replace is very weirdly presented compared to everything that has come

Not to crack open a very annoying semantic argument again but our vision of the 3D world is just a 2D plane so having "3D" - by which I guess you mean perception of depth through parallax - would do little to ease visualization of

Wow, he sure gets a lot of clout - his name showing up in this internet thread half a millennium later - for an achievement with so many qualifiers!

There's an enormous amount of work to do before what you're saying can be possible. All of existing mathematics has to be encoded as a wikipedia-style library in whatever flavor of theorem prover will win this round (Coq? Lean?) a

It's a pretty easy defense when you look at the alternatives, as in who came before (Batista) and what the alternate-world versions of Cuba look like - it's doing incredibly well compared to other island nations in the Caribbean,

I don't buy this. A thrown object is in orbit around the earth's center of mass if one were to treat it as a point mass. Since the earth is (roughly) spherical its gravitational pull is equivalent to being a point mass. The thrown

I think it would also require that gravity doesn't obey the inverse-square law, so stays constant in magnitude throughout the entire vertical component of the trajectory. An infinitely-flat earth would also mean the force vector points

I like to think of it this way. Compare mathematical axioms and rules of logic to the starting configuration and rules of a board game, let's say chess. All moves in chess follow from the very simple rules of chess. Every possible boar

Only tangentially related to your comment but it was recently pointed out to me that the trajectory of thrown objects is really an ellipse, not a parabola, since they're in a (very short!) orbit while airborne. Of course parabolas are
