Mathematics has an uncanny ability to describe the physical world. It elegantly explains and predicts features of space, time, matter, energy, and gravity. But is this magnificent scientific articulation an invention of the human mind or is mathematics indelibly imprinted upon the substrate of reality? #BrianGreene and leading thinkers parse the thorny problems of math’s existence.

This program is part of the Big Ideas series, supported by the John Templeton Foundation.

Participants:
David Z. Albert
Sheldon Goldstein
Silvia Jonas
Max Tegmark

Brian Greene

ABOUT DUET JUSTUS

Hi! We are Michael + Jenny Justus. We post videos on our life of alternative + sustainable + healthy living. Our desire to live a more meaningful life led us to concoct a crazy plan: Downsize our belongings, ditch the "9-5," and move full-time into a solar-powered, self-sustainable tiny home on wheels with our two dogs, Chase + Roni. Taking this leap into the unknown has completely transformed our future, so be sure to hit that SUBSCRIBE button, join the Justus League, and follow along to see where the journey take us!
