Quotes from (the other) Oppenheimer

Frank Oppenheimer (Robert's little brother) was a creative and charming pacifist. So charming, in fact, he was even beloved by his FBI tail (assigned because of his membership in the Communist party for their racial integration campaigns). Oppenheimer believed that students should be able to do fundamental lab experiments at any time, so created a library of permanent experiment stations which eventually morphed into the Exploratorium. He was also known for integrating art and science (or maybe was just trying to convince his artist friends to help construct the museum):

"Artists and scientists are the official 'noticers' of society. They notice things that other people either have never learned to see or have learned to ignore, and communicate those 'noticings' to others."

Oppenheimer and Richard Feynman were good friends, and a quote often attributed to Feynman was more broadly stated by Oppenheimer:

"Understanding is a lot like sex: It has a practical purpose but that's not why people do it."

Social network activity and social well-being

Just submitted the final version of this paper:

It's the product of another fantabulous summer with the Facebook Data Scientists. This time we surveyed about 1200 English-speaking Facebook users, asking them validated social psych scales measuring social capital and loneliness (e.g. "I come in contact with new people all the time" or "There are several people I trust to help solve my problems".) We paired their self-reports with communication activity on the site.

The work is based on the numerous studies that Nicole Ellison, Cliff Lampe, and Chip Steinfeld have done at MSU, connecting self-reports of Facebook use with social capital. Since we had granular activity data on server logs, we extended their work to look at different kinds of communication, particularly (1) directed communication (e.g., interacting with individual friends / sending messages / writing on each other's walls), and (2) passive consumption (e.g., reading stories about friends in the newsfeed). Turns out directed communication acts as expected (people who have strong relationships tend to communicate heavily with individual friends), but passive consumption is associated with greater feelings of loneliness. Since it's a cross-sectional study, we can't tell if clicking on feed stories makes people feel lonely, or lonely people tend to click on more feed stories, but we'll be able to tease out causation in future waves of the study.

We also validated the Facebook Intensity Scale; people are great at self-reporting their number of FB friends (duh) and pretty good at reporting time on the site. But attitudinal questions about their engagement with the site don't correlate to any measurable activities (like content production, repeat visits in a month, etc.)
