What is an anaphoric function / macro? I've seen this term floating around and I don't know what it means!

Most "hard results" in any subfield of math cannot be derived from pure categorical nonsense like adjunctions. At some point, you have to roll up your sleeve and do the work. How would you prove the tychonoff theorem purely with a

The math of QM underpins so much of modern technology, like transistors, MRIs, high precision clocks.. I feel like there's been a humongous failure of science communication if the applications of QM aren't obvious to you :( I don&

And what's the problem with living in an ivory tower, as someone who also lives in one? A monad is a mathematical idea. It has some learning curve, some inherent complexity that you can't magically solve. The post you're mock

I am very interested to learn about your workflow. What language do you program in? How does acme help programming in this language? Do you have a video or a stream I could watch? I'd love to know!

The original papers that introduced quantum mechanics might well be unreadable and mired in jargon. However, the community has come together, digested these ideas, and written textbooks that are accessible to anyone with a minimum of prepar

Zig documentation isn't crap; the documentation *does not exist* yet. There's an important difference between the two which seems to be ignored. Zig is young. They're spending their time maturing the core ecosystem --- the co

Idempotence is a desirable property of systems whereby repeating an action has no effect. Mathematically, an operator is idempotent if f(f(x)) = f(x). Idempotence is handy because it implies that one can retry safely if one isn't sure

I'd like to learn nuclear science. Where would I begin? I know basic classical mech, quantum mech, and classical field theory.

I don't doubt it, but I don't immediately see the proof either. What's the key idea?

I don't follow the comment about analyticity. I thought fields were real analytic, which meant one needed to use a power series to expand them, which has a potentially infinite amount of information in the Taylor coefficients? So I don

What are these different types of codes you mention? Got a textbook/lecture series to learn more? :)

Do you have a textbook in mind to teach high schoolers QFT? I'm dubious one could write such a textbook, but I'd love to be proven wrong. I ask since I have taken a course on QFT lite. We had to spend three weeks just doing tensor

I don't grok the real difference between the positive and negative rights example. Do these lead to different policy decisions? I'd like to know.

I'd like some intuition --- is that very low frequency? Is that very high power? Can I have some context for how I should think about 82 hz and multi megawatt? (For example, I know that few bits a minute = well, that's a couple AS

Does the trie help in memoizing the edit distance between multiple words? Or do you pay the O(n^2) cost per word? I'd love to hear details of how this works!

What IDE do you use for racket? In emacs, I've found SLIME and its associated debugger to be more powerful than GEISER. I never could come to like Dr. Racket due to its lack of autocomplete and things like parinfer / paredit.

Yes, which is why a photon experiences zero proper time.

I would say that this is intuitive. For any direction you pick, there are (n-1) orthogonal directions in nD space. It's only natural that the expected inner product drops to zero.

Do correct me if I'm wrong: I thought Spin(3) was a double cover, with the quaternions being one sheet of the covering, that of the connected component of the identity?!
