The Half-Life of Facts #224

August 02, 2013

This episode was recorded when Science for the People was called Skeptically Speaking.

This week, guest host Marie-Claire Shanahan spends an hour exploring knowledge and certainty, and how they change over time. She’ll speak to Samuel Arbesman, applied mathematician and fellow at the Institute for Quantitative Social Science at Harvard University, about his book The Half-Life of Facts: Why Everything We Khow Has an Expiration Date. And we’re joined by computer science and biology professor Mark Daley, to discuss the value of using computational thinking to better understand everything from biology to music.
