The [masked] lecture series at the Kaufmann Theater at the American Museum of Natural History sponsored by the Amateur Astronomers Association begins on October 19, 2012. Many of the lectures are excellent!
Michael Paul of Penn State will give a talk titled: "The Google Lunar X PRIZE: The Launch of Private Exploration of the Solar System".
The best way to get to the Kaufmann Theater is to enter the museum from the south side of the building, in the middle of the block on 77th street. You will see a grand arched staircase; the entrance is under the staircase. You will pass guards, and enter into a large room with a magnificent dug-out canoe from the Pacific Northwest. Turn left. Ahead of you, you will see the "Anne and Bernard Spitzer Hall of Human Origins", with three skeletons at the entrance to the hall (a human skeleton, that of a chimpanzee, and a Neanderthal, AKA, "Bill", "Chris", and "Harry"). Just before entering the Human Origins hall, you will see a corridor to your right, with display cases of lovely mollusks along the wall. Go down that hallway past the mollusks, and you will see a hallway to your left and an information desk. At the end of this hallway, you will see the Kaufmann Theater ahead of you. That is where the lectures are held.
