Christina Hoff Sommers in The American:
Math 55 is advertised in the Harvard catalog as “probably the most difficult undergraduate math class in the country.” It is legendary among high school math prodigies, who hear terrifying stories about it in their computer camps and at the Math Olympiads. Some go to Harvard just to have the opportunity to enroll in it. Its formal title is “Honors Advanced Calculus and Linear Algebra,” but it is also known as “math boot camp” and “a cult.” The two-semester freshman course meets for three hours a week, but, as the catalog says, homework for the class takes between 24 and 60 hours a week.
Math 55 does not look like America. Each year as many as 50 students sign up, but at least half drop out within a few weeks. As one former student told The Crimson newspaper in 2006, “We had 51 students the first day, 31 students the second day, 24 for the next four days, 23 for two more weeks, and then 21 for the rest of the first semester.” Said another student, “I guess you can say it’s an episode of ‘Survivor’ with people voting themselves off.” The final class roster, according to The Crimson: “45 percent Jewish, 18 percent Asian, 100 percent male.”
Why do women avoid classes like Math 55? Why, in fact, are there so few women in the high echelons of academic math and in the physical sciences?
