In this episode Jason and Josh talk with Tom Murphy, author of the blog Do The Math, about the inherently unsustainable nature of modernity and the delusion of infinite growth on a finite planet. As part of this they discuss his early retirement from academia as a successful astrophysicist at the University of California, his growing interest in indigenous wisdom and lifeways, the long view of earth history and where we’re going, and his realization that the end of modernity doesn’t mean the end of humanity
Tom’s university bio:
I am a Professor in the physics department at UCSD, and the Associate Director of CASS, the Center for Astrophysics and Space Sciences. From 2003–2020, I led the APOLLO project as an ultra-precise test of General Relativity using the technique of lunar laser ranging. My interests are transitioning to quantitative assessment of the challenges associated with long-term human success on a finite planet.
In November 2021, I was one of five founders of the Planetary Limits Academic Network, aiming to connect scholars from all disciplines who are concerned about the deep systemic challenges humanity faces this century. Our "launch" paper gives the background, titled Modernity is Incompatible with Planetary Limits: Developing a PLAN for the Future.
In 2014, I started a company (Aircraft Avoidance Systems) to provide safety devices for observatories using lasers for scientific research.
