The late Carl Sagan, probably the greatest science communicator of the 20th century, would have been 75 today.
In memory of his contributions to science and the public understanding and appreciation of it, eSkeptic has made available a lecture series on Sagan and a compendium of articles about him.
Every book that I have read by Sagan has been a tremendous pleasure, but The Demon-Haunted World: Science as a Candle in the Dark remains seminal reading for every skeptic and science enthusiast.
Update: Click here to watch James Randi's hour long talk in rememberance of his friend Sagan.
