I saw some of the same talks and posters but did not see Petra. I missed the street scene...I don't have a microscope, but I do have partial use of a telescope. However, yesterday at AGU a scientist I know asked if I had a microscope with me (really). She needed it for her poster, which is about the cause of the greatest dying in earth's history..(Permian-Triassic boundary...250 million years ago. She (and someone I work with) are in the middle of a huge controversy...
