TGS18 Thomas Murphy The Great Simplification

On this episode, we meet with Professor of Physics at UCSD and the Associate Director of CASS, the Center for Astrophysics and Space Sciences, Tom Murphy.

Murphy shows us how continued growth and energy use is an impossibility if continued at our current trajectory. How does physics constrain our planetary ambitions? Murphy helps us do the math.

To help us align with a post-growth trajectory, Murphy offers suggestions for how humans can begin to treat nature as well as we treat ourselves — and why we must care about the future in order to create a brighter one.

About Tom Murphy

Tom Murphy is a Professor in the Physics Department at UCSD, the Associate Director of CASS, the Center for Astrophysics and Space Sciences, and is the author of Energy and Human Ambitions on a Finite Planet.

From 2003–2020, Murphy led the APOLLO project as an ultra-precise test of General Relativity using the technique of lunar laser ranging. Professor Murphy’s interests are transitioning to quantitative assessment of the challenges associated with long-term human success on a finite planet.

In French, we have a motto that says that a simple drawing is often better than a long explanation. Jean-Marc Jancovici Carbone 4 President

That’s very understandable because with left atmosphere thinking, one of the problems is that you see everything as a series of problems that must have solutions. Iain McGilchrist Neuroscientist and Philosopher

We can’t have hundreds and hundreds of real relationships that are healthy because that requires time and effort and full attention and awareness of being in real relationship and conversation with the other human. Nate Hagens Director of ISEOF

This is the crux of the whole problem. Individual parts of nature are more valuable than the biocomplexity of nature. Thomas Crowther Founder Restor

The Forgotten Skills of Dying and Grieving WellWith Stephen JenkinsonThe Great SimplificationEp 190 | Stephen Jenkinson

In Western culture, topics surrounding death and dying are often considered taboo and are generally avoided in everyday conversations. But this reluctance to fully acknowledge and integrate death as a natural part of the human experience has rendered us less able to cope with the end of life and less prepared to show up for ourselves and the people around us as we inevitably navigate loss. But what if a more skillful engagement with death and grief could actually offer us a more mindful approach to living?

The Silent CollapseWith Oliver MilmanThe Great SimplificationEp 189 | Oliver Milman

Insects, bugs, creepy-crawlies – these small animals are often considered a nuisance (or worse) by humanity, bringing up an ongoing desire to kill or mitigate these “pests” that plague our backyards, homes, and gardens. But we’re beginning to see that, despite our cultural misconceptions, insects are actually at the foundation of our biosphere, food supply, and nearly every life process on Earth. This makes recent reports of rapidly declining insect populations all the more troubling – but can we recognize the vital importance of insects and reverse the harm we’ve done before it’s too late?

Nothing Can Stop This TrainWith Lyn AldenThe Great SimplificationEp 188 | Lyn Alden

Money, debt, and finance shape the lives of everyone globally, including through the policies and actions of national central banks – yet even those who are well-versed in these subjects often miss the full scope of these intricate relationships. For the average person, headlines about mounting government debt and surging interest rates often feel like a confusing and concerning trend. What can we learn from historical cycles, global energy dynamics, and the differing fiscal strategies of nations about the trajectory of the world economy?
