Women and Physics

Women in Physics Match Men in Success, by Kenneth Chang, in the NYT (excerpts below):

Only about one-eighth of the physics professors at Harvard are women, a statistic that might seem to support the recent assertion by its president, Dr. Lawrence H. Summers, that fewer women than men are willing to make the necessary sacrifices. He also suggested that a difference in "intrinsic aptitude" between the sexes might help explain the disparity.

A report released Friday by the American Institute of Physics offers a contradictory conclusion: after they earn a bachelor's degree in physics, American women are just as successful as men at wending their way up the academic ladder....

Dr. Ivie said the main reason fewer women made it to the top in physics was simply that fewer started at the bottom. At each job level, she said, the fraction of women matched what would be expected for women advancing at the same rate as men. And at top-tier universities, the percentage of female physics professors is low because many current professors earned their Ph.D.'s in the 1970's or earlier, when the field was almost entirely male, and have not yet retired.

Instead, the sex disparity arises earlier in the pipeline, between high school and college. Nearly half of students taking high school physics are girls, but fewer than a quarter of the bachelor's degrees in physics go to women. "That's where the drop-off point in physics is," Dr. Ivie said. "That's where they need to look." ...

Dr. Ivie also said that in suggesting that men and women might have different intrinsic aptitude in science, Dr. Summers did not take into account the continuing progress of women in fields like physics. While women earned only 18 percent of the Ph.D.'s in the United States in 2003, that is far higher than 1970, when the percentage was 2.4.

"If it's differences in innate ability, I don't know what innate abilities would have changed so quickly," Dr. Ivie said. ....
