That surprised me too. I found that Mathematica could solve it if you give it the denominator as 1-u^2 for the eventual substitution. Perhaps it just doesn't try very hard to look for substitutions? I could believe it not giving a lo

Are you perhaps thinking of https://thetech.com/ ? I'm not sure in what sense the Technology Review is a student newspaper - to my knowledge (and checking a few bylines), the journalists are not students.

The article you link about repeatedly heated oils, specifically reusing oil when deep frying. That doesn't seem relevant to the use described above.

I kind of get the sense Baez is being polite and humble there, not wanting to say something is nonsense if others seem to find value in it. That said, I think I agree with Baez about the actual mathematical content of the paper. That is, th

The issue I'm having with the claims is that their use of the word "model" seems to connote exactly of the opposite of what someone reading the paper without seeing their definition would suggest, and indeed what other commen

I'm disappointed, I was looking forward to seeing a new fractal. The onion curve in 2d is just a spiral, as mentioned, but the word "spiral" doesn't appear at all. I think this paper is mostly without merit, unfortunatel

I'm having trouble following the proof of lemma 1, and I can't tell if it's the notation being different from what I'm used to. Is the expression for gamma prime equal to negative the square of the distance between x and

As pointed out in that aside, the general vector-bivector multiplication isn't needed to evaluate the reflection case, but I agree it's a little unsatisfying to sweep that under the rug. You can work everything out by breaking it

I was hoping to read some code analysis that supported your claim of off-by-one being more common in 0-based languages, but all I see in your [3] is a few different speculative reasons - am I missing something? Off-by-one can show up in a b

The algorithm won't assign them that way in that case. A more thorough explanation is elsewhere in the comments, but essentially if Alice got placed at B despite preferring A, they had to have gotten bumped from A, then bumped someone

The article seems deliberately deceptive, entirely ignoring the second half of what it claims net neutrality means except to criticize Google for not treating all the bits it sends the same, and then encouraging us to think net neutrality c

Debugging tools in n64 emulators (such as nemu64) are sufficient to make tracking down particular game logic more in the neighborhood of a fun puzzle than a slog through (roughly) a megabyte of assembly. Super Mario 64 in particular has had

Galois generators of the sort in the article can be described naturally using the finite field Z_2[x]/p(x), that is, polynomials with coefficients taken mod two, where we consider polynomial p(x) is equivalent to zero. If p has degree

To add to this, the "walking in place" animation happens when Mario's position + velocity would end up out of bounds, which the game doesn't generally permit. When the player turns and allows the speed to drop, the motio

I'm having trouble with your "therefore" conclusion. The projection of the perimeter of the inner box could easily be shorter than the sum of the lengths of the projections of each edge. It seems like you need a less obvious
