Summer stories: Cobi Smith on Rachel Carson and Daniel Horsley on Georg Cantor

This summer we're featuring classic tales from the science storytelling event, the Laborastory.First up, science communicator Cobi Smith tells the story of American biologist Rachel Carson, whose writings about DDT—including the book Silent Spring—made her a villain to some and a hero to many.And then, mathematician Daniel Horsley explains how Georg Cantor's ideas about infinity, although eventually vindicated, made him unpopular in his time too.
