In the final episode of this season, we hear from a NASA researcher whose expertise spans from studying samples in deep, untouched regions of our planet all the way to organic chemistry happening in space. We consider the possibility of other, past origins of life on Earth and look at the rich potential to learn from sample return missions, including the recent OSIRIS-REx mission that retrieved samples of the asteroid Bennu...
In this episode, we examine how the course of human history has shaped our scientific knowledge, why the physics community prioritizes some questions over others, and why progress in complex systems research is especially difficult. Academia continues to operate within set boundaries and students are taught certain concepts as fundamental and to skirt others completely. However, the history of science demonstrates that such concepts aren’t always set in stone...
How do groups solve problems? Are there conditions that create a pathway to innovation and groundbreaking inventions? In today’s episode, we look at the science of collectives to learn about the patterns that emerge as human societies grow, the importance of a collective structure to foster ideas and create impact, and – from collectives like ants and immune systems – the importance of veering off the beaten path to become better at exploring and discovering.
In the first two episodes of this season, we’ve examined how fundamental rules like scaling laws constrain evolution for all forms of life. But if everything is bound to these core rules, then why do we see exceptions? In this episode, Abha and Chris get into the incredible diversity of plants and animals on this planet, where that diversity comes from, and if it’s possible to make forecasts about the biosphere, just like we do for the weather. And, what happens when biodiversity is threatened?
In this episode, Chris and Abha explore how life originated here on earth and how we might identify it in other parts of the universe. They ask two researchers about the signature characteristics of life and what common dynamics we might see among organisms outside our planet. They’ll also delve into assembly theory, a recent concept that looks at the construction of objects as a way to universally quantify life, which has ignited debate within the scientific community.
Humans can live up to age 100, and not 1000 – why? Are there limits in how much our brains can think and compute? The laws of physics can help explain a lot, both about our own human bodies and how we are connected to life all around us.
Episode Title and Show Notes:
106 - Michael Garfield & David Krakauer on Evolution, Information, and Jurassic Park
Welcome to Complexity, the official podcast of the Santa Fe Institute. I'm Michael Garfield, producer of this show and host for the last 105 episodes...
One way of looking at the world reveals it as an interference pattern of dynamic, ever-changing links — relationships that grow and break in nested groups of multilayer networks. Identity can be defined by informational exchange between one cluster of relationships and any other. A kind of music starts to make itself apparent in the avalanche of data and new analytical approaches that a century of innovation has availed us...
For centuries, Medieval life in Europe meant a world determined and prescribed by church and royalty. The social sphere was very much a pyramid, and everybody had to answer to and fit within the schemes of those on top. And then, on wings of reason, Modern selves emerged to scrutinize these systems and at great cost swap them for others that more evenly distribute power and authority...
