RS134 - Michael Shermer on: "Science drives moral progress"

Release date: May 17, 2015

Photo by Jeremy DangerCommon wisdom holds that the world is getting more violent, but is that really true? Leading skeptic Michael Shermer, professor and author of many books on science, morality and skepticism, argues to the contrary. Shermer's thesis in his recent book, "The Moral Arc: How Science Leads Humanity Toward Truth, Justice, and Freedom," is that as science has advanced our understanding of the world, we have become more willing to expand our circle of empathy beyond our own provincial "tribes," and more able to design our societies to encourage human flourishing.

Dr. Michael Shermer is the Founding Publisher of Skeptic magazine, a monthly columnist for Scientific American, a regular contributor to Time.com, and Presidential Fellow at Chapman University. His new book is The Moral Arc: How Science and Reason Lead Humanity Toward Truth, Justice, and Freedom.

RS133 - Sean Carroll on "The Many Worlds Interpretation is probably correct"

Release date: May 3, 2015

Sean CarrollIn this episode of Rationally Speaking, Caltech physicist Sean Carroll describes an "embarrassing" state of affairs in modern physics: that we still don't know how to interpret quantum mechanics, almost a century after its discovery. Sean explains why he thinks the "Many Worlds Interpretation" (MWI) is the most plausible one we've got, and Julia explores his thoughts on questions like: Can MWI be tested? Is it "simpler" than other interpretations, and why? And does MWI threaten to destroy our systems of ethics?

Sean Michael Carroll is a research professor in the Department of Physics at the California Institute of Technology. He is a theoretical cosmologist specializing in dark energy and general relativity.

 Sean's pick: "Quantum Computing since Democritus"
