Sorry, this was incorrect. In this integral we're just calculating the geometrical question, what is is the 5d volume of the collection of 3 points whose circumcenter is on {(x, 0) : x in [0, 1]}. So the "overall" probability

You pointed out one error in your own answer, here's another. I haven't figured out the adjustments, but presumably they cancel. You've done ∫₀¹ ∫₀¹⁻ᶜ (2π r)³ dr dc However, - the `dr` integral is assuming that the radii are

You've made the choice of (Locked Door, Open Window) ~ (Good SQL usage, XSS Vulnerability) which seems to be an incorrect rebuttal. Your example doesn't contradict "only as strong as its weakest link", here the weakest l

To add on to the defense in another comment, I don't think the point of the article is a rust-v-python comparison. Sure, unoptimized-python2rust2optimized rust was a part of the clickbait 180,000x title but... - the author explicitly

Undefined behavior is considered worse than crashing, which is typically the alternative when reaching "unreachable" codepaths. Compare these two blocks similar to the article switch (ch) { case 'a': do_a(); retu

Let me rebuke just one part of the post: the example with Newton's laws. Of course everyone knows that Navier-Stokes is just a very nice approximation. That doesn't mean that mathematical results about Navier-Stokes can't imp

You can even make it polygonal. Even more interesting, you can make it non symmetrical, contradicting the article's claim that dice must be symmetrical to be fair. You make an (n-2)-gon cylinder. This has n faces (the sides, the to

Can't we just appreciate that both points of views are helpful? Instead of thinking that one is better, and saying that therefore, the other sucks. Both of them explain different things. The "it's just a basis transformatio

Ok, I can agree that we shouldn't design notation around their limitations. And I do like what they do in SICM. But, I'm just trying to root for the point up-thread: >It seems tempting to have a single unambiguous notation fo

The great thing is we're not constraining our notation. As reikonomusha said, the standard notation is easier to read. Other notation is better for programming or certain things, and that's what we use there. Re: your last parag

Isn't the conclusion, "all particles have free will"? So, the arguments conclusion is pretty far from its premise. "All numbers are larger than 5" is very far from "some number is larger than 5". And, wh

It depends on what you mean by a math problem. It seems a common idea is: A math problem is a question asking for the set of solutions to some mathematical equation, and only the actual solution is useful. But I would include all of the f

Your edit is correct. Non-transcendentals are algebraic by definition, and the algebraic numbers are countable.

Yeah, I guess those are the only ones I can think of that are more famous than the golden ratio :)

"Although no other algebraic units are as famous as the golden ratio, they are of central importance to algebra." Arguably more famous algebraic numbers include: 0, 1, The square root of two, the square root of any integer, i, any

This reminded me of driving the tanks in the video game Grand Theft Auto, Vice City. If you wanted to go faster, a good option was to turn the turret backwards and fire.

Let me try to explain Schanuel's conjecture a little bit, if you're lost on words like transcendence degree. This turned out longer than I hoped so I hope it's not just a wall of text. sqrt(2), π, π/2, π^2, and e are al

I prefer that point of view if you want to understand Euler's identity, and I find John Baez does it even better: http://math.ucr.edu/home/baez/trig.html The Baez article does leave it to the reader to convince himself that exp(i*theta) i
