An old amazing topological trick…

The tutorial of the day: Turn a carrot into a cube-octahedron!

Does every simple closed curve in the plane contain the vertices of a square?

No one knows, but the answer to this question is positive if the curve is sufficiently regular.

A 3D regular hexahedron solid (cube) passing through a 2D plane:

In geometry, the **isogonic center** (aka Fermat–Torricelli point) of a triangle, is a point such that the total distance from the three vertices of the triangle to the point is the minimum possible.

Can you alter this figure-eight-shaped pastry in order to thread the stick into the second loop? Obviously, you cannot unthread the stick from the pastry nor cut the pastry in any way!

The trick is explained in my book: “Impossible Folding Puzzles and Other Mathematical Paradoxes” available on Amazon: https://amazon.com/dp/0486493512/?tag=archimelabpuz-20
