““Turning a Snowball Inside-Out”Turning a Snowball Inside-Out”
A model of the Morin Surface = Half-way point of sphere eversion The challenge is to turn a sphere inside-out:
Surface may pass through itself, but no ripping, puncturing, creasing allowed,
e.g., this is not an acceptable solution: PINCH
Sphere Eversion ProcessSphere Eversion Process But there are more contorted paths
that can achieve the desired goal. Bernard Morin figured out one such path. Charles Pugh made models from chicken wire. Nelson Max made a first computer simulation.
