Today’s episode asks how scientists see the world. We bring you two stories — one about a math guy and a bug guy. First, how the math guy, or one of our country's greatest mathematicians, Steven Strogatz, first became enchanted with math as a kid. Then, a story about a human developing a soft corner (literally) for a fly that lived in his scalp — the botfly. Evolutionary biologist Jerry Coyne went on a research trip to Costa Rica and returned home with a botfly feeding on his flesh. His friend Sarah Rogerson was a little less charmed, and they both were surprised by the creature that ultimately emerged from his head.
