Man! Buying a Gömböc is surprisingly expensive.
(Please nerd-snipe me.)
#Gömböc

Here is the Gömböc I had machined for my brother as a birthday gift.

For centuries, mathematicians believed that any convex, homogeneous object must have at least three points of stable equilibrium. This principle seemed unshakable-until the #Gömböc defied expectations.

3D printed gömböc emerged today.

Model seems viable by the looks of these brief tests.

@andreas_jechow a related fascinating thing:
a #Gömböc is a body which uprights itself and has only a single stable point of equilibrium.
Nature evolved this shape too, e.g. in the shells of Turtles, which helps them to get back on their feet in case they're flipped:

@jens the corresponding geometric body with the same capabilities as a tortoise to never get really stuck on in its back is a #Gömböc:

Meilleur cadeau : un #gömböc ! Mieux qu'un culbuto, cet objet a une unique position d'équilibre stable et une unique position d'équilibre instable - qu'il quitte à la moindre perturbation. Mais en plus, il est homogène et convexe (deux points dans ou sur l'objet peuvent être reliés par une ligne droite qui reste à l'intérieur du gömböc).
Il tire son nom du hongrois "gömb" pour sphère, objet avec lequel il partage beaucoup de propriétés.

Mannaggia!

Ho scoperto che le #galline di @rapitadaglialieni e @Yaku non fanno delle uova: fanno dei #gömböc

Gömböc—The Shape That Shouldn't Exist

In this video I show you a Gömböc. This is a shape that has only two equilibrium points—one stable and one unstable, instead of the usual minimum of 4. It is self-righting no matter how you set it down. .STL file for the Gömböc: https://www.thingiverse.com/thing:523643 Checkout my experiment book: https://amzn.to/2Wf07x1 Follow me on Twitter: https://twitter.com/theactionlabman Facebook: https://www.facebook.com/theactionlabofficial/ Instagram: https://www.instagram.com/therealactionlab/ Watch other popular videos from my channel Shooting a Nerf Gun Backwards While Driving At The Bullet's Speed Forward https://youtu.be/436i_cTdtVo Superhydrophobic Knife Slices Water Drops in Half https://youtu.be/Ls_ISb7lG-I Real-Life Invisibility Cloak Can Hide Anything!
