Because of a Mathematician From Rural Virginia Work on Global Positioning, You Have No Excuse for Getting Lost

Article excerpt

Gladys West, a mathematician from rural Virginia, performed the calculations that made modern GPS possible, work so foundational that without her decades of satellite and radar computations, the technology pinpointing our location on Earth wouldn't exist. West's career, largely unrecognized for decades, has recently gained attention as her contributions to geodetic science have been properly credited. Her story exemplifies how critical infrastructure we take for granted, the turn-by-turn directions on our phones, the precision guiding emergency responders and military operations, rests on the intellectual labor of scientists who worked quietly in government research roles. West's insatiable thirst for knowledge, applied to complex mathematical problems involving ellipsoids and satellite data, fundamentally reshaped how humans navigate the world.
