If you can bear the humidity, there’s stuff going on in New York that you might wanna do! And it’s summer, so maybe you can actually do it!

• Do you miss your astrophysics class from last semester? Good news! The World Science Festival, an annual event celebrating science, culture, and art, began on Wednesday morning and will run through Sunday. Stephen Hawking will be there! Events are all over the city. [NY Times]

• Oh, and the festival’s opening night gala included an adaptation of the children’s book “Icarus at the Edge of Time,” which was written by festival co-founder and Columbia professor Brian Greene and his wife. It’ll be reperformed on Sunday for those who missed out. [NY Times]

• Speaking of Greene, he thinks we might all be holograms! No, seriously. [AP]

• If science isn’t your thing, you can head on over to Riverside Church on Tuesday to hear Noam Chomsky talk about the problems facing Haiti in the aftermath of the earthquake.  [PR Newswire]

• If that’s too serious for you, you could always stay inside and work on upping your friend count on Facebook. Don’t let it get too high though, because, as the J-School’s Dean of Student Affairs Sreenath Sreenivasan will tell you, Facebook cuts you off at 5,000. [NY Times]
