Congratulations to African-American mathematician Katherine Johnson who is celebrating her 100th birthday today. Her calculations of orbital mechanics at NASA were critical to the success of the first U.S. manned spaceflights. The Oscar-nominated film Hidden Figures honored her genius in 2016 with actress Taraji P. Henson portraying the young Johnson’s reputation for brilliantly forecasting flight trajectories using complex manual computations. Her leadership helped to establish confidence in the use of computers to perform the same tasks, yet astronaut John Glenn refused to fly unless Johnson manually verified the computer’s numbers. WATCH a wonderful clip… (1918)

The West Virginia math prodigy graduated from high school when she was just 14 years old, and her college, West Virginia State, had to add new math courses just for Katherine.

Katherine Johnson in 1966 – NASA

At NASA, which was still racially segregated at the time, her knowledge of analytic geometry helped make quick allies of her white male bosses. She worked out rendezvous paths for the Apollo lunar lander on flights to the Moon and, later her calculations were essential to launching the Space Shuttle program. While the racial and gender barriers were always there, Katherine says she ignored them, and never really felt them. She was assertive, asking to be included in editorial meetings (where no women had gone before). She simply stated that she had done the work and that she belonged… There is even a Barbie doll based on the female role model.

And, on this day in 1791, John Fitch was granted a United States patent for a boat propelled by steam power.Steamboat-Ben Campbell-Mississippi River-1920

Working on lakes and rivers, at first with the use of paddles, these boats would eventually revolutionize the commercial transportation of passengers and freight, particularly along the Mississippi River, as described by Mark Twain in his books.
