So here's something new. We've just launched a beautifully designed on-being Discovery Engine.

Plug in your favorite conversation or an interview that set your imagination off in new directions,

and you'll be offered a constellation of kindred conversations to keep going deeper and farther.

When I enter last week's interview with Arnold Eisen, some of the threads the engine suggests

include Amokai Laole-Levy and David Brooks and E.J. Dion.

You can also explore hundreds of on-beings shows by theme and create a playlist tailored to your

curiosities. All of that at discover.on-being.org. On-being is brought to you by the John Templeton

Foundation. The Templeton Foundation supports academic research and civil dialogue on the deepest,

most perplexing questions facing humankind. Who are we? Why are we here? And where are we going?

Theoretical physicist Lisa Randall started out seeking answers to questions and standard model physics

and ventured into pondering extra-dimensional worlds. Now she's moved into eliminating

what she calls the astounding interconnectedness between fields which have previously operated

more autonomously. Astronomy, biology, paleontology. She's pursuing a theory that dark matter might

have created the cosmic event that led to the extinction of the dinosaurs and hence humanity's

rises as a species. We explore what she's discovering as well as the human questions and takeaways

her work throws into relief. You know, it's okay to be aware of our limitations as human beings

that these are things that make it harder. It doesn't make it impossible and that's the beauty of

science is that we can go beyond these prejudices if you like these intuitions that we have built on our

ordinary everyday experience. It allows us to think about things that seem obviously wrong. They're

not obviously wrong. They're just not obvious to us. I'm Christa Tippett and this is on being.
