Hats off to the American Mathematical Association for creating a poster entitled, "Women Doing Mathematics". It highlights the accomplishments of nine women and has a personal quote from each about their interest in Math.
Print it out and put it up in your department, the library, the mall, your kid's school, etc. This is a great poster to have in circulation. If I was a young woman considering a career in STEM a poster like this would have far more reach than Computer Engineer Barbie.
