The Brilliant Mr. Feynman (Update)

Hey there, it's Stephen Dubner. A couple years ago, we made a three-part series about the physicist Richard Feynman, and we heard from so many of you that we have decided to replay it now. This is part two. We have updated facts and figures as necessary. The biggest update you'll want to keep in mind as you listen today is that both the Feynman family home and Zorthian Ranch were destroyed in the LA wildfires last year.

As always, thanks for listening. On July 16, 1945, a team of U.S. scientists based in Los Alamos, New Mexico, conducted what their leader, J. Robert Oppenheimer, had named The Trinity test.

They were detonating a new kind of bomb way out in the desert a couple hundred miles from the secret lab at Los Alamos where they had created it. The US president Harry Truman seemed to fully grasp the magnitude of this moment. It is an atomic bomb. It is a harnessing of the basic Power of the universe.

That is the first couple of minutes. The rest is $1.
