Fun fact: the blood donation compatibility chart forms a Sierpinski triangle. This can be seen by writing the blood types as 3D binary vectors (A,B,rh), with O- being (0,0,0) and AB+ as (1,1,1), and subtracting recipient from donor. (image source: openmd.com/guide/blood-ty…)

One of the worst scifi movie tropes is when characters analyze some alien material and say "it doesn't match anything in the periodic table", as if aliens are just building everything out of transactinides.

Wikipedia is now full of essentially duplicate articles on several math subjects, because the machine learning crowd insists on recreating their own version of everything.

Have you ever seen anyone attempting to visualize the action of unitary transformations beyond 2 dimensions? (so no Bloch sphere stuff)

Was looking for some videos on wavelets and stumbled upon this nice little quote by Ingrid Daubechies from an interview, and figured it would be good share. From here: youtube.com/watch?v=kUgfyS…

Google insists on using my old phone I don't have anymore for verifying an account that is already set up for my current phone in 2FA... And there's no way to fix this and no support channel. Awesome.

Involute gears, developed by Euler, have the nice property of being able to mesh with any gear with the same tooth parameters, including racks (linear gears). This nice animation shows this by using racks at several directions to simulate the turning profile of the other gear.

This is cool! We've come such a long way with this tech. I believe MRIs are one of humankind's greatest achievements, and the math, physics and engineering behind them is awesome. People should be more excited about these wonderful devices!
