Particles of Thought

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 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 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.

Federico Rossano caught dogs doing something that looks a lot like telling jokes. The cognitive scientist shares what he learned from speaking with dogs. Dogs can smell, hear, and in some ways see better than humans. So why wouldn’t they have something interesting to say if they could speak? Federico has found a dog's mind may be closer to a human toddler's than anyone previously believed and believes we are close to learning important lessons from our canine companions.

Federico Rossano didn't care about talking dogs until science made it impossible to ignore. The cognitive scientist joins Hakeem to reveal how a viral social media trend turned into the largest citizen-science study of animal communication ever conducted, tracking over 10,000 dogs and 700 cats across 47 countries. But how can you trust a study done by volunteers from around the world? Federico shares how he secured quantity and quality data and the messages dogs want to share.

Brent Minchew could have a plan to stop Thwaites Glacier, AKA the “Doomsday Glacier”, cold in its tracks. That’s good news because if this one glacier slips into the sea, it could flood coasts across the planet. The Caltech glaciologist covers what makes the “Doomsday Glacier” the single biggest wild card in sea level rise, the simple idea that could freeze it back to its bed, and his own improbable journey from 9/11 first responder to two of the world's top science institutions. It's a conversation about glaciers, courage, and what it takes to change the story.

A former U.S. Marine, he now co-leads efforts to test real-world interventions that could stabilize the world's most vulnerable glaciers.

Brent Minchew responded to the Pentagon on September 11th, 2001. Before he was a glaciologist at Caltech, he was a marine aboard the Marine One presidential helicopter and was one of the first on sight after the deadly attack. Brent joins Hakeem to trace his unlikely path from a working-class upbringing in Texas to a career studying the world's most extreme ice sheets. And he traces how his experience in the military informs his scientific mission planning and decision making.

Brent Minchew has a plan that could  stop the “Doomsday Glacier” in its tracks, and we don’t even need new technology to do it. The Caltech glaciologist returns to unveil an intervention that could save coasts around the world: refreezing Thwaites Glacier to its own bedrock using passive principles of physics. Brent walks Hakeem through the natural process that slows glaciers down, and lays out a plan to investigate if they can truly deploy it on the world's most precarious glacier.

Brent Minchew is an expert on the glacier that could devastate the world’s coastlines. As a glaciologist at Caltech, he's spent his career tracking Thwaites Glacier, AKA the "Doomsday Glacier." It’s roughly the size of Florida and already losing 50 billion tons of ice a year. Brent joins Hakeem to break down what scientists know – and don’t know – about the glacier that could determine our future. How certain is that “doom,” and how fast could it happen? They nerd out about what happens as glaciers slip into the sea, how satellites can measure glacier movement down to the millimeter from orbit, and how Thwaites might be the single most important glacier on the planet.
