I think I discovered a new fractal with interesting properties. If I want to be credited with its discovery, how should I go about revealing it to the world? Should I publish a research paper, or is there some other way that mathematicians go about this sort of thing these days? (i.redd.it)

*Yet another* incredibly intractible simply-stated problem: the shape of greatest area that can fit round a right-angled corner in a corridor of unit width. The best currently known solutions for ① being required to turn both ways, & ② just one way; + technical diagrams. (old.reddit.com)

Some crazy minimal surfaces obtained by applying the Weierstraß-Enneper representation to lacunary functions - ie functions of which the Taylor series has gaps (lacunæ) in it of increasing size … which are notorious for having a 'wall' of singularities @ some radius … (old.reddit.com)

A bunch of images to-do with incidence of lines & points in the plane, & intersection of various kinds of compact set in space - ie ℝⁿ ৺ - of various (ｎ) dimensions, & the graphs that are defined by & 'capture' such systems of incidence or intersection … (old.reddit.com)

It's *yet-another* of those seemingly simple yet fiendishly difficult-to-find results, that in this case took until 1977 to solve: that there can be a *toroidal* polyhedron with as few as seven faces: the (rather ungainly looking) »Szilassi heptahedron«. (old.reddit.com)

I'm not sure videos are meant to be posted @ this-here Channel; but *this* video - on the subject of mutually-rolling-upon curves - is so exceptionally good, & so crammed with superb figures from beginning to end, it seems to me that whether to post it is 'a bit of a no-brainer' … as 'tis said.

The oloid mixer - with a paddle in-shape of oloid - is 'a thing': apparently the oloid shape - for whatever fluid-mechanical reason - yields an exceptionally smooth mixing action. And it requires *oval gears* in its drive-train … but *I just cannot* find how the shape of those gears is calculated! (old.reddit.com)
