"I remember that the advanced calculus course was taught by a graduate student and met at 7 A.M. every morning, and not only was I the only woman, I was the only black in the class. I sat right next to the door and I was truly isolated. I had no one to talk to in the class; even though there were two other girls in the class, they avoided me like I was some sort of plague, because if you're not a white woman, you can't associate with anybody except maybe handicapped men."
