Today, November 9th, is Carl Sagan's birthday. I think we all love Sagan enough to give his birthday a shout-out from Wikipedia Fb and @Wikipedia. Here's some proposed copy, but I know we have a following of Sagan, so feel free to jump in! Thanks for reviewing.

Fb: "A central lesson of science is that to understand complex issues (or even simple ones), we must try to free our minds of dogma and to guarantee the freedom to publish, to contradict, and to experiment. Arguments from authority are unacceptable." - Carl Sagan. Today is his birthday!

Fb: Carl Sagan's ability to convey his ideas allowed many people to understand the cosmos better—simultaneously emphasizing the value and worthiness of the human race, and the relative insignificance of the Earth in comparison to the Universe. Today is Carl Sagan's Birthday!
