Before John Glenn orbited the earth or Neil Armstrong walked on the moon, a group of dedicated female mathematicians known as "human computers" used pencils, slide rules and adding machines to calculate the numbers that would launch rockets, and astronauts, into space. Among these problem-solvers were a group of exceptionally talented African American women, some of the brightest minds of their generation. Originally relegated to teaching math in...

While mathematics itself may be a formidable subject for many, the lives and accomplishments of history's greatest mathematicians-from Pythagoras to Cantor-offer fascinating reading. In this delightful and informative recounting, for example, we learn how Pascal's life was abruptly changed by a family of fanatical bonesetters, how Descartes was influenced by three dreams, and how the scholarly Swiss Leonhard Euler (whose famous conjecture was finally...

"The story of Katherine Johnson, an African American mathematician whose work was critical to the first US space flight"--

Meet Katherine Johnson, a brilliant mathematician who worked at NASA in the early 1950s until retiring in 1986. Katherine's unparalleled calculations (done by hand) helped plan the trajectories for NASA's Mercury and Apollo missions (including the Apollo 11 moon landing). She is said to be one of the greatest American minds of all time.

The woman at the heart of the New York Times bestseller and Oscar-winning film "Hidden Figures" shares her personal journey from child prodigy in the Allegheny Mountains of West Virginia to NASA human computer and her integral role in the early years of the U.S. space program.

Explores the previously uncelebrated but pivotal contributions of NASA's African American women mathematicians to America's space program, describing how Jim Crow laws segregated them despite their groundbreaking successes.
