The Formula For Perfect Parallel Parking : NPR
The formula for the perfect parking job was recently worked out by mathematician Simon Blackburn, professor at the University of London. Stanford mathematics professor Keith Devlin tells NPR's Audie Cornish "it's actually a very clever use of simple mathematics." The most complicated part, Devlin says, is our good old friend the Pythagorean theorem. That's a squared plus b squared equals c squared, as you'll remember from your high school geometry class, no doubt. "The formula tells you exactly how much extra space you need, beyond the length of your vehicle, in order to park it in a simple, reverse-in, straighten-the-wheels, switch-the-engine-off move," Devlin explains. In other words, no back-and-forth, no see-sawing — the perfect parallel parking job.
