An aerospace engineer who worked for NASA for over 40 years, Dr. Christine Darden is one of the mathematicians that the book and movie Hidden Figures was based on. Darden eventually would lead the sonic boom team, going on to become the first African-American woman in senior management at NASA.

In this intimate conversation with a16z’s general partner Jeff Jordan, held at the SF Jazz Center, Darden shares with Jordan how she first fell in love with geometry and math; the effect that Sputnik had on our culture (and her); and what it was like to work at NASA in the 1960s. And finally, Darden shares with us all the secrets of the sonic boom.
