Second, today is the eighth anniversary of Stephen Jay Gould's death. When I was a teenager, my brain flitted between pseudosciences (I wrote my senior term paper on UFO abductions), like a hummingbird trying to pull nectar from plastic flowers. Gould's eloquent writings on the history of science and evolution were in part what set me nice and straight, to flowers that don't just look pretty but offer actual nourishment. Thanks, Steve.
