Stevenson University's "Expanding Your Horizons" event came off quite smoothly yesterday, with 150 middle-school girls invading campus to take hands-on science and mathematics workshops from female professionals. No small amount of thanks is due to Nicky, who coaxed several of her colleagues at Johns Hopkins to provide presentations. One of them (on fashion science, from a chemist who works for Proctor & Gamble) turned out to be the hit of the day. Not having the proper chromosomes to engage in direct participation, I contented myself with watching several activities and ferrying the keynote speaker from her hotel to the campus, and thence to the airport. A repeat engagement next year seems almost certain.
