The edges of the universe (if it has them) are not too far away for the mind of Chanda Prescod-Weinstein. It's on Earth where she's had to deal with limits.
As one of the very small sisterhood of Black women to get a PhD in physics, she has been reminded often of the things people see in her besides her agile mind. She considers both Out There and Here in her book The Disordered Cosmos: A Journey into Dark Matter, Spacetime, and Dreams Deferred.
Dr. Prescod-Weinstein teaches both science and women's/gender studies at the University of New Hampshire. She gives us a lesson on her book.
