So... It's Not Flat?

Richard Thaler at Edge asks people for their favorite examples of wrong scientific beliefs, such as the world being flat and more. Scripps' Eric Topol responds that in medical school he was taught that one cells differentiated into heart muscle or nerves that they can never regenerate. "Wrong!!

"To me, the story of science has been the story of augmenting our perceptions, and realizing that they had to be augmented in the first place" Lowe says.
