March 29: There is an amusing article on scientifciamerican.com about Paul Erdos on what would have been his 100th birthday. I actually met him very briefly while a first year graduate student at the University of Colorado. He was treated somewhat like a rock star by the math department; when he took walks around the campus he would be followed by adoring faculty and graduate students.
