MATHEMATICS

The king of math vloggers, 3Blue1Brown, just released a video about the corona virus and exponential growth. It's probably a better Internet reaction to the epidemic than putting sliced apples in your bottom, which is what Facebook and Twitter and advising people to do.

This blog post on factorials of fractions helped clear up a tricky bit of math for me. Actually, pretty neat!

• Terence Tao: Almost all orbits of the Collatz map attain almost bounded values. I only made it a few pages in, but I feel privileged to share the same universe as this guy, and that conjecture.
• Weirdo the cat-killing superchicken.
• Sandi Metz, who is an excelling programming writer, once came up with four rules for object-oriented programming. I've been more-or-less trying to stick to them for a while now. Good or not good?
• I'm obsessed with movies that can be edited down to less than three minutes without losing any plot points or characterization. Someone managed do the same to the entire run of the Sopranos.
• Tom Hanks MegaFacts. Includes him rapping while doing a Harry Morgan impression??
• John Waters has been releasing a list of his favourite movies of the year every year for two decades. Watching these is a new life goal.

• An article about Theodore de Bry, an extremely talented Netherlandish/Belgianish artist who did dozens of engravings of the New World without ever having been there.
• Every six months or so I find myself watching Bernie Mac's performance on Def Comedy Jam (NSFW). Even though the jokes aren't really that funny, it's one of the great stand up performances of all time.
• Hyper-negative ancient Sumerian creation myth (NSFW).
• Seanbaby spent what I imagine was hundreds of hours finding weird things in pre-code horror comic books (NSFWish).
• You might have seen a clickbaitish Youtube video or the like saying that 1+2+3... = -1/12. Here's an article dealing with a lot of the math around that in a pretty simple way, with a link to Terence Tao's more hardcore, scary, NSFW explanation at the end.
• A Bestiary of Single-File Implementations of Programming Languages.

• Steamed Dagoth Ur
• Hyper-Detailed, Picture-Filled Pre-War History Of The Ocarina
• Automatic Box Plan Generator
• banned.h
• Gut-wrenching: Italian Waiter Grinds Fresh Black Pepper Onto Daughter’s Grave
• Byrne's Euclid is a strange Victorian edition of Euclid using colours instead of letters. I'm not sure whether it's really easier for children, but it is interesting to look at. Some excellent person made a classy online edition.
