Recently I was one of several Googlers who volunteered at the Expanding Your Horizons in Science and Mathematics conference at Mills, where I also teach. This annual event provides career panels and hands-on workshops to encourage middle-school girls to keep studying science and mathematics as they enter high school. I led a workshop, "How to Build a Computer," in which the students learned binary arithmetic and built a half-adder.
I don't know who had more fun, the girls or the volunteers! Google is a sponsor of the national Expanding Your Horizons Network, whose workshops have reached over 625,000 girls.
