To be fair, I lived in the burbs of DC and I live in SF proper. So it's not really an apples to apples comparison for me. There is certainly tons of museums and such in dc to see and they all have various programs. I may very well have just not been clued in to what was going on, but it didn't take long for me to find those types of things here in SF. I never really found them living near dc my whole life (and 7 years after college).

For science stuff in the bay area the best resource is probably http://www.bayareascience.org/ Follow the twitter feed and you'll see there are generally 4 or 5 things a day going on just in science related fields.

For art/social things I generally check out squidlist.com, but many other sites like sfist.com have a ton of things to do listings daily.

Plus there's just a ton of orgs in and around the city that have ongoing lecture series type of events. Asian Art Museum, Cal Academy of Science, Grey Area Foundation For the Arts, Friday's at the DeYoung, etc.

Tons of stuff...and a lot of it goes on outside of SF proper too with Berkeley and Stanford being so close.
