Have you heard of the Caltech bubble? It’s a very, very real phenomenon where extremely busy students, splitting their time between homework and lectures and research and limited personal time, stop reading the news and rarely become aware of current events beyond what happens on their own campus. While understandable, it’s rather annoying and somewhat dangerous (do you want the people you are training to go forth and change the world to not be aware of what is going on in the world?). Not everyone on campus lives in the bubble, however. There are a few organizations on campus that focus onsocial justice and activism, including the Social Activism Speaker Series (SASS), run by the Caltech Y, Caltech PRISM, the Caltech Feminist Club, and Women in Physics, Mathematics, and Astronomy. The Caltech Diversity Center hosts talks through the Food For Thought program (I recently posted about a lecture on the politics of protest by Caltech professor Dr. Jennifer Jahner), andadvises manystudent clubs (like PRISM and the Feminist Club). These groups have becomemore and more active over the four years I’ve been here, and it’s extremely heartening to see that more and more students are getting involved in issues that don’t directly affect their everyday lives on campus.
