gee, thanks for helping me solve my nondeterministic polynomial-time complete problem!

well i was searching for something in my undergrad files, and found this hypotenuse x circumference ship art my friend requested once during quizbowl practice (i know that is A Sentence, now we don't have time to unpack all of that) that took around 15 min, given pi day was yesterday i thought it'd be thematic to share!

math lesbians? math lesbians

i gotta start posting my old art more..........

That feel when the math textbook is like, we would like this reasonably sounding conjecture to be true but due to the Alexander Horned Sphere we know it to be false. Like so rude of Alexander to do that to us ngl.

Polyhedron of the Day #207: Hexagonal bifrustum

The hexagonal bifrustum is is the fourth in an infinite series of bifrustum polyhedra. It has 14 faces (12 trapezoids, 2 hexagons), 24 edges, and 18 vertices. It can be constructed by truncating the polar axis vertices of a hexagonal dipyramid, or by attaching two hexagonal frustrums at their bases. Its dual is the elongated hexagonal dipyramid.

Me, explaining how DEs office hours go: Yeah so you go to his office hours with confusion--i.e. questions--and you do get your questions answered at some point, but he also says a lot of other things so you leave with new confusion.

My friend who is not at this university or studying math anymore: Wow this really is call of cthulu

(I relayed this story to one of my classmates who just nodded and made a vague sound of agreement.)

Mathematical fun fact of the day 4. You can divide a hexagon into nine identical convex pentagons.

I can't believe how successful my (basically nonexistent) plan for getting my prefered officemates next year have been so far.

The reason a plan exists even in the slightest is the fact that the two people I want to share an office with barely knew each other (as of... two weeks ago). But apparently, it was sufficent to just continue on with my usual existence within the department and bet on their shared interest in PDEs being enough to make them want to be friends lol.

(In the first and second year cohorts--at least 25 people total--only 3-4 people currently want to do PDEs. I'm not one of them, but I like analysis a lot more than algebra so close enough.)
