Happy Birthday Carl Sagan!

November 9, 1934 – December 20, 1996
If you wish to make an apple pie from scratch, you must first invent the universe. —Carl Sagan
FEW CELEBRITIES IN SCIENCE have done more for the promotion of science, reason, rationality, and critical thinking than Carl Sagan, whom we remember today upon the occasion of his birthday: November 9, 1934. Carl would have been 77 years old today. Happy Birthday Carl!
