The Secret Science Club has a free monthly gathering at Union Hall in Park Slope at 8p.m. for all those whom were shamed out of getting their engineering and astrophysics degrees.  Microbiologist and ecologist Dickson Despommier from Columbia University discusses the idea of creating sustainable farming in urban skyskrapers over tasty specialty cocktails, The Mile Highball (the part that is not free).  The lecture is sandwiched by music and video and a Q&A session.  Get smart and get drunk.
