Tonight I went to hear astrophysicist Neil deGrasse Tyson speak at the Free Library of Philadelphia.  Hands down, one of the best lectures I’ve ever been to!  It may have even surpassed Jane Goodall.  If you have a chance, I highly recommend going to hear him speak if he’s going to be in your city.  And who thought that a physicist could have a sense of humor?!–hilarious!  And such a sweet man.  He is the host of NOVA’s ScienceNow on PBS and director of the Hayden Planetarium at the Museum of Natural History in NYC…amongst many accomplishments.  Good stuff!
