2 women do the math about women and math — and science and engineering — and say it may take 100 years before 50% of professors in the STEM fields are women.

Cheryl Geisler, dean of the faculty of communication, art, and technology at Simon Fraser University, says:

"In the last four years we're seeing 27 percent of new hires in science and engineering are women... It was 25 percent earlier in the decade, so it's just been creeping up."

Her co-author, Deborah A. Kaminski, a professor of mechanical engineering at Rensselaer Polytechnic Institute, says:

At that rate, it may be 2050 before 50 percent of new hires in science and engineering are female... And even after one-half of all faculty members hired are women, "it will likely take at least another 40 years before the actual population of science, engineering, and mathematics professors is 50 percent women"...

They did the math about women and math. Care to check their work, guys?
