This episode features Rick Nevin, an economist who is known for his research suggesting that lead is one of the main causes of crime.

And is it possible that getting rid of lead could reduce the crime rate down to zero?

Not enough people know about the Mohists, a strikingly modern group of Chinese philosophers active in 479–221 BCE. This episode features Chris Fraser, expert on Mohism and professor of philosophy at the University of Hong Kong. Chris and Julia discuss how the Mohists put their philosophy into practice and got Chinese leaders to hold off on starting wars; how their philosophy was similar to and different from modern consequentialism; why their movement died out, and what modern groups like Effective Altruists can learn from their story.

RS 222 - Spencer Greenberg and Seth Cottrell on "Ask a Mathematician, Ask a Physicist"

Release date: December 2nd, 2018

Spencer Greenberg and Seth Cottrell

This episode features the hosts of "Ask a Mathematician, Ask a Physicist," a blog that grew out of a Burning Man booth in which a good-natured mathematician (Spencer Greenberg) and physicist (Seth Cottrell) answer people's questions about life, the universe, and everything. Spencer and Seth discuss the weirdest and most controversial questions they've answered, why math is fundamentally arbitrary, Seth's preferred alternative to the Many Worlds Interpretation of quantum physics, how a weird group of parapsychologists changed the field of physics, and whether you could do a Double Slit Experiment with a Cat Cannon.
