How math's 'hairy ball theorem' could explain bad hair days
SMRTR summary
The "hairy ball theorem" — a real concept in topology — proves it's mathematically impossible to comb a sphere's surface without creating at least one cowlick or bald spot. While human heads don't perfectly qualify as spheres, this theorem has real-world applications, including explaining why a windless eye must exist in every hurricane and influencing nuclear fusion research.
