How are they going to teach a robo taxi #NonEuclideanGeometry ?

Two images, the left is a pile of UK coins, the right is the same image inverted about the circle around the central 10p coin.

#mathartmarch Day31: Change.

Let me present Change - Changed. This is an inversion in the circle, pixel by pixel, using some python code and the vector formula: x'=centre+(x-centre)*radius^2/(|x-centre|^2)

The animation on the left shows clearly that the shortest path between two places on Earth is the straight line.

Unbelievably, there are possible worlds where this would NOT be the case! 🧵 ...
