What is the strangest math that turned out to be useful?
-
If I recall correctly, one mathematician in the 1800s solved a very difficult line integral, and the first application of it was in early computer speech synthesis.
the man you're thinking of is, I believe, George Boole, the inventor of Boolean algebra.
-
The math fun fact I remember best from college is that Charles Boole invented Boolean algebra for his doctoral thesis and his goal was to create a branch of mathematics that was useless. For those not familiar with boolean algebra it works by using logic gates with 1s and 0s to determine a final 1 or 0 state and is subsequently the basis for all modern digital computing
George Boole introduced Boolean algebra, not Charles. Charles, according to this site on the Boole family, he had a career in management of a mining company.

Shoutout to Satyendra Nath Bose who helped pioneer relativity as a theoretical physicist because he didn't want to study something useful that would benefit the British.

Was he trying to dunk on his professors?
Yes and no

There have been a number of Scientific discoveries that seemed to be purely scientific curiosities that later turned out to be incredibly useful. Hertz famously commented about the discovery of radio waves: “I do not think that the wireless waves I have discovered will have any practical application.”
Are there examples like this in math as well? What is the most interesting "pure math" discovery that proved to be useful in solving a real-world problem?
Having watched all the veritasium math videos I feel like all the major breakthroughs in math were due to mathemicians playing around with numbers or brain teasers out of curiosity without a concrete use case in mind.

Be honest, how many unofficial experiments were there?
You ever just start lasering shit for kicks?

Of course, but 1 is the loneliest number.
2 is as bad as 1: it's the loneliest number since the number 1.

Does this count? Because it really is wtf.
The exact example I also thought of from the question! Well done
-
Doom absolutely counts!
Quake, not Doom. Doom didn't use true 3D rendering and had almost no dynamic lighting.

Probably not as many as we'd like to think. I recently got to run a few days of tests at Lawrence Livermore National Labs with an absurdly massive laser. At one point we needed to bring in a small speaker for an audio test. It took the lab techs and managers about two hours and a couple phone calls to some higher ups to make sure it was ok and wouldn't damage anything. There's so much red tape and procedure in the way that I don't think there's an opportunity to just fuck around. The laser has irreplaceable parts that people aren't willing to jeopardize. Newer or smaller lasers are going to be more relaxed. This one is old enough to be my father, and it's LLNL's second biggest single laser iirc. And they are the lab using lasers for fusion, so they have big lasers.

A brain teaser about visiting all islands connected by bridges without crossing the same bridge twice is now the basis of all internet routing. (Graph theory)
freaking freaky little Russian outpost that one is. Bridges galore

The invention of the number 0, the discovery of irrational numbers, or l the realization that base 60 math makes sense for anything round, including timekeeping.

Non-Euclidean geometry was developed by pure mathematicians who were trying to prove the parallel line postulate as a theorem. They realized that all of the classic geometry theorems are all different if you start changing that postulate.
This led to Riemannian geometry in 1854, which back then was a pure math exercise.
Some 60 years later, in 1915, Albert Einstein published the theory of general relativity, of which the core mathematics is all Riemannian geometry.
This won't make any sense to any of you right now, but: E = md^3^

Well Wassily Wassilyevich Leontief won a Nobel prize in economics for his work on this subject that might help you get started
There's no such thing as a Nobel Prize in economics. Economists got salty about this and came up with the Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel, and rely on the media shortening it to something that gets confused with real Nobel Prizes.

60 was chosen by the Ancient Sumerians specifically because of its divisibility by 2, 3, 4, and 5. Today, 60 is considered a superior highly composite number but that bit of theory wouldn’t have been as important to the Sumerians and Babylonians as the simple ability to divide 60 by many commonly used factors (2, 3, 4, 5, 6, 10, 12, 15) without any remainders or fractions to worry about.

It’s crazy how engaging and well done Veritasium videos are and they’re just free to watch on YouTube.

Donuts were basis of the math that would enable a planned economy to be more efficient than a market economy (which is a very hard linear algebra problem).
Basically using that, your smart phone is powerful enough to run a planned economy with 30 million unique products and services. An average desktop computer would be powerful enough to run a planned economy with 400 million unique products and services.
Odd that knowledge about it has been actively suppressed since it was discovered in the 1970s but actively used mega-corporations ever since…
Maybe they're scared that project Cybersyn would actually work

Fair point

As far as I know, matrices were a "pure math" thing when they were first discovered and seemed pretty useless. Then physicists discovered them and used them for all sorts of shit and now they're one of the most important tools in in science, engineering and programming.

It's imaginary numbers. Full stop. No debate about it. The idea of them is so wild that they were literally named imaginary numbers to demonstrate how silly they were, and yet they can be used to describe real things in nature.
