Particles of Thought

Dennis Whyte has designed a fusion reactor for Mars, and it turns out the red planet has plenty of fusion fuel. The MIT nuclear scientist joins Hakeem to explore fusion's wildest applications: spacecraft propulsion, space stations, and even a shield that stops radiation. While they’re at it, Dennis and Hakeem discuss the roadblocks and risks still left to solve in nuclear fusion.

Guest Bio:
Dennis Whyte is the Hitachi America Professor of Engineering at MIT and former director of the Plasma Science and Fusion Center. He co-founded Commonwealth Fusion Systems, the MIT spinout building a compact fusion reactor using record-breaking superconducting magnets, and is now the CEO of the United Kingdom's Atomic Energy Authority.

Dennis Whyte helped spark a multi-billion-dollar industry from a spool of tape. The nuclear scientist and entrepreneur explains the nitty gritty of nuclear fusion through the multitude of businesses that are chasing nuclear fusion. Dennis walks Hakeem through the origin story of Commonwealth Fusion Systems, the company he co-founded from a class assignment, and reveals how a new superconducting material discovered in the 1980s finally made compact fusion possible.

Dennis Whyte studies the physics that powers every star in the universe, and he says it can power your house, too. Now the CEO of the UK’s Atomic Energy Authority and nuclear scientist at MIT, Dennis joins Hakeem to break down what fusion actually is, why it packs 10 million times the energy density of gasoline, and who is making the biggest investment in this massive energy field. Dennis unpacks the surprisingly direct link between a society's energy use and its economic prosperity, and reveals why fusion might change everything.

Federico Rossano convinces Hakeem that animals have a lot more to say than we've given them credit for. The cognitive scientist shares the origin story behind his record-breaking study of talking dogs, the evidence that some pets may understand more than a human toddler, and what primates reveal about the roots of communication itself.

Federico Rossano is an Associate Professor of Cognitive Science at UC San Diego and director of the Comparative Cognition Lab, where he studies communication and social cognition across humans, primates, dogs, and cats. He leads the world's largest study of button-trained pets, and his research is featured in the NOVA documentary Can Dogs Talk?

Federico Rossano says the secret to speaking with apes is trust. For primates, the world is full of high-stakes friends and foes, and of course, there are always predators to worry about. Our closest relatives see the world a little differently than we do, and that can teach us a lot about our own communication. Federico is a cognitive scientist who questions the assumptions beneath human conversations, and in this episode, he shares lessons from the animal kingdom with Hakeem. From apes besting children in “the peanut puzzle” to baboons that seemingly sense how to travel together, there’s lots to learn.
