Walter S. McAfee is the African American mathematician and physicist who first calculated the speed of the moon. McAfee participated in Project Diana in the 1940s - a U.S. Army program, created to determine whether a high frequency radio signal could penetrate the earth’s outer atmosphere. To test this, scientists wanted to bounce a radar signal off the moon and back to earth. But the moon was a swiftly moving target, impossible to hit without knowing its exact speed.
In an age of racism and sexism, Katherine Johnson broke both barriers at NASA. She calculated the trajectory of man’s first trip to the moon, and was such an accurate mathematician that John Glenn asked her to double-check NASA’s computers. To top it off, she did it all as a black woman in the 1950s and ’60s, when women at NASA were not even invited to meetings. And you’ve probably never heard of her.
