Ever wondered how Google Maps knows exactly where you are? It's not magic, it's math! Trilateration uses
GPS satellites to pinpoint your precise location. Spherical geometry and trigonometry work in harmony to
calculate distances and angles. Meanwhile, the Kalman filter algorithm is the mastermind behind smooth
navigation, seamlessly combining data from GPS, accelerometers, and gyroscopes. With every turn and every
step, math is the unsung hero guiding you to your destination. Next time you use Google Maps, give credit
to the math that makes it all possible! Math truly makes all the right turns
Math is all around us, in every step, turn, and direction!
