I can no longer include the Wikipedia links, because the article was removed, but we have Time Magazine's own.
SCIENTISTS AND THINKERS
These were so hard!!!! I missed the first three (although I'd read Carson's book; I just didn't remember her name as the author), but then I rebounded and got the last 17 for 17/20. I feel more proud at that than the first three combined. See how you do.
