In 1962, astronaut John Glenn refused to fly until one woman checked the electronic computerโs math by hand.
Her name was Katherine Johnson.
At the time, NASA had new electronic machines, but trust in them was low. Glennโs instruction was blunt: "Get the girl to run the numbers. If she says they're good, I'm ready to go."
She ran them. He flew. ๐
Johnsonโs brilliant trajectory calculations carried Alan Shepard into space, put Glenn in orbit, and helped bring Apollo 11 safely back from the Moon.
And she did all of this while working in a segregated building, using a segregated bathroom, at an agency that initially classified her as a "computer" rather than a mathematician.
She passed away in 2020 at the age of 101, having already received the Presidential Medal of Freedom from Barack Obama.
A profound reminder that true expertise, resilience, and human insight will always outshine raw processing power.
