#mathober day 17: Dimension Invariance
A coffee cup is a donut
but certainly not
a napkin
even one with a hole.No matter how hard you
squish and stretch
R^2 and R^3 can't ever be
homeomorphic. - blinryblinry@chaos.socialOct 18, 2026, 12:00 PM
#mathober day 18: Biflecnodal Point
Still traveling, and deprioritizing making big drawings! So here's a haiku! :)
One inflection point
on top of a second one
that's a biflecnode! 
Fractal Kittyfractalkitty@mathstodon.xyzOct 17, 2026, 5:21 AM@blinry nice!

Dimension is the exact thing that homotopy forgets about
DerPumu (he/him)DerPumu@mstdn.gamesOct 18, 2026, 5:43 AM@blinry but only if it has one handle, right?
Daniel Bohrerdaniel_bohrer@chaos.socialOct 18, 2026, 1:10 PM@blinry when two inflections touch, it is called as such: that's biflecnode! 🎶
