Katherine Johnson, a mathematician and scientific genius, who broke through race and gender barriers in the once segregated NASA died today at 101 years of age. Her calculations were critical contributions to the first manned space flight, and those that came after. The world has lost a trailblazer, pioneer, and hero. May her legacy live on!

Girls are capable of doing everything that men are capable of doing. Sometimes they have more imagination than men.
