Women in Science
I know few other women who do what I do. What I do is write about science, mainly physics. And to do that, I spend a lot of time reading about science, talking to scientists, and struggling to understand physics. In fact, most of the women (and men) I know think me quite queer for actually liking physics. "How can you write about that stuff?" they ask, always somewhat distrustfully. "I could never understand that in a million years." Or more simply, "I hate science."
I didn't realize what an odd creature a woman interested in physics was until a few years ago when a science magazine sent me to Johns Hopkins University in Baltimore for a conference on an electric phenomenon known as the Hall effect. We sat in a huge lecture hall and listened as physicists talked about things engineers didn't understand, and engineers talked about things physicists didn't understand. What I didn't understand was why, out of several hundred young students of physics and engineering in the room, less than a handful were women.
Sometimes later, I found myself at the California Institute of Technology reporting on the search for the origins of the universe. I interviewed physicist after physicist, man after man. I asked one young administrator why none of the physicists were women. And he answered: "I don't know, but I suppose it must be something innate. My seven-year-old daughter doesn't seem to be much interested in science."
It was with that experience fresh in my mind that I attended a conference in Cambridge, Massachusetts, on science literacy, or rather the lack of it in this country today. We three women—a science teacher, a young chemist, and myself—sat surrounded by a company of august men. The chemist, I think, first tentatively raised the issue of science illiteracy in women. It seemed like an obvious point. After all, everyone had agreed over and over again that scientific knowledge these days was a key factor in economic power. But as soon as she made the point, it became clear that we women had committed a sad social error. Our genders were suddenly showing; we had interrupted the serious talk with a subject unforgivably silly.
For the first time, I stopped being puzzled about why there weren't any women in science and began to be angry. Because if science is a search for answers to fundamental questions then it hardly seems silly to find out why women are excluded.
A lot of the reasons women are excluded are given by the Massachusetts Institute of Technology experimental physicist Vera Kistiakowsky in a recent article in Physics Today called "Women in Physics: Unnecessary, Injurious, and Out of Place?" The title was taken from a nineteenth-century essay written in opposition to the appointment of a female mathematician to a professorship at the University of Stockholm. "As decidedly as two and two make four," a woman in mathematics is a "monstrosity," concluded the writer of the essay.
Dr. Kistiakowsky went on to discuss the factors that make women in science today, if not monstrosities, at least oddities. Contrary to much popular opinion, one of those is not an innate difference in the scientific ability of boys and girls. But early conditioning does play a stubborn and subtle role. A recent Nova program, "The Pinks and the Blues," documented how girls and boys are treated differently from birth—the boys always encouraged in more physical kinds of play, more active explorations of their environments. Sheila Tobias in her book Math Anxiety showed how the games boys play help them to develop a natural understanding of speed, motion, and mass.
The main sorting out of the girls from the boys in science seems to happen in junior high school. As a friend who teaches in a science museum said, "By the time we get to electricity, the boys already have had some experience with it. But it's unfamiliar to the girls." Science books draw on boys' experiences. "The examples are all about throwing a baseball at such and such a speed," said my stepdaughter, who barely escaped being a science drop-out.
The most obvious reason why there are not many more women in science is that women are discriminated against as a class, in promotions, salaries, and hirings, a conclusion reached by a recent analysis by the National Academy of Science.
Finally, said Dr. Kistiakowsky, women are simply made to feel out of place in science. Her conclusion was supported by a Ford Foundation study by Lynn H. Fox on the problems of women in mathematics. When students were asked to choose among six reasons accounting for girls' lack of interest in math, the girls rated this statement second: "Men do not want girls in the mathematical occupations."
A friend of mine remembers winning a Bronxwide mathematics competition in the second grade. Her friends—both boys and girls—warned her that she shouldn't be good at math: "You'll never find a boy who likes you." My friend continued nevertheless to excel in math and science, won many awards during her years at the Bronx High School of Science, and then earned a full scholarship to Harvard. After one year of Harvard science, she decided to major in English.
When I asked her why, she mentioned what she called the "macho mores" of science. "It would have been O.K. if I'd had someone to talk to," she said. "But the rules of behavior were such that you never admitted you didn't understand. I later realized that even the boys didn't get everything clearly right away. You had to stick with it until it had time to sink in. But for the boys, there was a payoff in suffering through the hard times, and a kind of punishment—a shame—if they didn't. For the girls it was O.K. not to get it, and the only payoff for sticking it out was that you'd be considered odd."
