MathType - The Hairy Ball theorem or Hedgehog theorem proven by Poincaré in the 19th century states that "you can't comb a hairy ball flat without creating a cowlick". A hairy doughnut
Hairy ball theorem A failed attempt to comb a hairy 3-ball (2-sphere), leaving a tuft at each pole A hairy doughnut (2-torus), on the other hand, is quite easily combable. - iFunny
