Found out from @isomorphisms post: isomorphismes.wordpress.com/… that this can be encoded as a lattice structure. So can in general refinement relations be modelled using lattices?

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-types)

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)

Ugh, why does Nature not export BibTeX?

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=kUgfySuF…

That illustration for this article is really damn nice. Excellent work there, @samuelvelasco!
In recent years, there have been at least five mathematical results that identify the “optimal” version of shapes, including the Möbius strip (with one twist), the three-twist Möbius strip and the simple knot. @KSHartnett explains how these shapes work, with graphics by Merrill Sherman: quantamagazine.org/mathemati…

Did this silly image a while back to illustrate my PhD research for some office poster thing that never materialized, so might as well post here.

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.

In September this year, someone changed the main image in the Jordan curve theorem Wikipedia article to the shape of country of Jordan. en.wikipedia.org/wiki/Jordan… I guess it's fine. (cc @depthsofwiki)

There's something kind of magical about doing arbitrary precision optimization and seeing how deep you can get a result.

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!

#OnThisDay 1978: Tomorrow's World gave audiences a true world first as Dr Peter Mansfield of the University of Nottingham demonstrated the first full body prototype device for Magnetic Resonance Imaging (MRI), allowing us to see inside the human body without the use of X-rays.
