As mentioned previously, tonight MIT alums geek out on nanotechnology in 15 cities around the US.
I speculated that non-alums might be able to get in if they try, and sure enough, it seems that they can — at least in the Bay Area, where the event appears to have opened up to the entire MIT Stanford Berkeley Nanotechnology Forum, which I believe is an open group not limited to those schools.
The registration link on their page is not the best one to use; use this one: http://www.mitcnc.org/Events_Single.asp?eventID=1363. This is only for the SF Bay Area event; in other cities you’ll need to dig around to find out if it’s possible to get in. –Christine
