Today we are talking about a gal who is a math genius. Her calculations were pivotal in getting the first American in space and back home safely. But it didn’t stop there, from the early days of NACA testing airplanes and rocket all the way to the Space Shuttle Program she was there crunching the numbers with pin-point accuracy. Today we’re making math a ton of fun and talking about the life and legacy of your gal, Katherine Johnson.
