#MathMonday I love it when there are useful, “everyday”, applications of a mathematical theorem. Here’s one of my favorites: Take a level table wobbling on uneven ground. The Intermediate Value Theorem guarantees that rotating the table in a circle, less than a quarter turn (for a 4-legged table), will find a spot where the table sits perfectly without wobbling! No need to shove napkins under the “short” leg. (#Proof available upon request.) #calculus #IVT
