Made a little writeup on my Sunday nerd snipe.

Generate videos in just a few seconds. Try Grok Imagine, free for a limited time.

This makes me think of my not being anonymous on the internet. I would rather the results of my actions reach my ears. (This is a statement about my use of the internet not a statement about what anyone else should do, people have different circumstances obviously)

Gottem.

Well I got all the edges sans the connectivity requirement. Pro: I wrote it in a way where this works for k-faces of n-cubes (higher dimensions). Con: In 4D my code would explicitly enumerate all 2^(32) possible subsets of edges (4-cubes have 32 edges).

The latest #3blue1brown video is dangerous, I saw the first few seconds and immediately had to pause it to try to solve it myself! Given an n cube, how many unique (up to rotation) connected partial n cubes can we construct out of (n-k) faces? There might be a cool fancy

Posting all my solutions at

Made this visualization while working on SICP problem 3.69 today. Strategy for a recursive algorithm is is: Take the blue piece first (dimension 0), then riffle the dimension 1, 2, and 3 pieces together.

Really nice explanation!

1-2lbs of home grilled fresh caught salmon could fix me.

@PStilance Also fun: Try doing $\sum_{n\in\mathbb{Z}} \pi \cot(\pi (z-in))$ and figuring out what elliptic function you're left with.

I'm sure I saw this in my complex analysis class but still, nice.

If you were born in 1980, this year will be the square of your age. Jealous

From https://t.co/sVlNTfKGpv . Really good lecture series as well:

Interesting problem

The list of leaders together with the log_10 of the corresponding prime factor, for your perusal. I guess this is the sequence I was thinking of, which is not in OEIS.

The clear outliers disappear with more information, sad day. (This is way further than I would have thought possible to continue the graph!!! I used factordb for the largest prime factors)

I knew someone had the factors in their pocket:

Hey um anyone have the largest prime factor of 67^67-1 laying around?

A letter from my local council announcing plans for a “Montorsoli school” made me wonder if it was a typo for “Montessori” … but on closer scrutiny, a religious order really is planning to name this facility after the 16th century Florentine sculptor & friar Giovanni Montorsoli.
