I’m in a week-long summerschool right now, in which a handful of well-known professors give expository talks about their field to graduate students and post-docs. Each talk is 75minutes long. The last speaker was male and very carefully referenced every figure, equation, numerical technique and result that he showed. Except for one figure. One figure in the whole 75 min talk was taken by a female professor in her physics lab. He did not reference her. On the same slide were references to other (male) researchers along with images of their photos or numerical results. After he talked about her photo, he did a double-take and said, oops, I forgot to reference Sarah …., dang. At least he mentioned her name. But, really, how did he forget? And how does that effect the female grad students here?
