When my brother taught math grad student 40 years ago, there were a lot of Jews in his classes, men and women He hadn't been in a place that had a lot of Jews before, and both the kippas and the scarves were a new thing for him to see.

Thanks for the nice words. My youngest daughter, while attending UCSC, dormed with a Jewish gal and got heavily involved in Hillel Foundation, a Jewish youth group. Doing so opened her eyes to all things Jewish, including seeing the kippas and scarves. Another daughter traveled for months all over Europe seeing the same, from Holland to Greece. I worried while she was there, but the experience was valuable to her. She settled down in Iowa, which is somewhat tame, but she has her memories to cherish.
