Items of interest:
-- Glenn Reynolds on asteroid defense, a subject I've been interested in since before they started making movies about it in the 1990s.
-- David Frum speaking on blogging at Bard's Graduate Center in NYC tonight; am unable to go but it is sure to be interesting.
-- Purchased a new book: The Measure of Manhattan: The Tumultuous Career and Surprising Legacy of John Randel, Jr., Cartographer, Surveyor, Inventor, by Marguerite Holloway, who worked at Scientific American before my time there. This is related, albeit tangentially, to my ongoing DeWitt Clinton/Erie Canal research.
