Richard Feynman's final years took him to surprising places with his companions, exploring his views on science, curiosity, and the impact of his testimony on public perception. The podcast also discusses his perspective on literature, embracing the unknown, and living with doubt. The hosts wrap up the series with updates on upcoming episodes and express gratitude to everyone involved.

Charles Duhigg, author of The Power of Habit, and Helen Czerski, physicist, discuss the challenges of communication, the importance of active listening, authenticity, and understanding communication techniques. They explore the impact of effective communication in bringing people together and building closer connections.

Helen Czerski, a physicist and oceanographer at University College London, dives deep into the ocean's role in climate regulation. She discusses how oceans absorb a third of our CO2 and 90% of excess heat. The conversation explores ocean physics, marine ecosystems, and the importance of understanding oceanic health in addressing climate change. Czerski highlights the risks posed by rising temperatures and human activities, urging a re-evaluation of our connection with oceans not merely as resources but as vital life support systems.

Physicist Helen Czerski talks bubbles, explosives, and the impact of ocean waves on history. She explores carbon movement in the ocean, misconceptions about ocean temperatures, and telling stories of the physics of the ocean. They also discuss changing the prison incentive structure and the importance of education in prisons.

The deepest parts of the Pacific Ocean have been largely unexplored for centuries. But now the ecosystem thousands of metres beneath the surface is under threat - from companies wanting to mine the seabed for rare metals and minerals.The proposals to allow deep-sea mining are centre-stage at global talks by the International Seabed Authority - the UN body in charge of regulation - and its members in Jamaica in the coming weeks. It comes after a two-year ban on the practice expired when countries failed to reach an agreement on new rules. Scientists fear a "goldrush" for precious metals beneath the oceans could have devastating consequences for marine life. But supporters argue that these metals are needed if the world is to meet the demand for green technologies - such as electric car batteries - that will be key in the fight against climate change.So is this a necessary step in the journey towards cleaner, greener technologies? Does climate change pose a bigger risk to our oceans overall? And what impact might mining have on this rare and delicate ecosystem?Shaun Ley is joined by:Pierre Josso, mineral geoscientist at the British Geological SurveyHelen Czerski, physicist and oceanographer at University College London and author of 'Blue Machine: How the ocean shapes our world'Toby Fisher, environment lawyer who has negotiated with the International Seabed AuthorityAlso featuring: Gerard Barron, CEO of The Metals CompanyPhoto: An animal from the deep Pacific Ocean known as a 'gummy squirrel'.

Physicist Helen Czerski and journalist Tom Heap discuss rewilding efforts and balancing human needs with nature's preservation. They explore bison reintroduction impacts, agricultural conservation in North Norfolk coast, and the harmonious relationship between humans and the environment.

To understand the world you need to understand the ocean. That’s the argument of physicist Helen Czerski who has long studied the complex ecosystems and forces that drive the ‘blue machine’ which covers 71% of our planet. Czerski joins Intelligence Squared to discuss her new book Blue Machine: How the Ocean Shapes Our World, and what we should know about these vast bodies of water – the waves, currents, invisible ocean walls and underwater waterfalls that are part of an interlinked system that shapes the world around us. In conversation with science editor of The Times Tom Whipple, Czerski discusses how, since the beginning of human civilisation, the oceans have been central to the way human societies have evolved and how threats like climate change and overfishing could threaten our future. We’d love to hear your feedback and what you think we should talk about next, who we should have on and what our future debates should be. Send us an email or voice note with your thoughts to podcasts@intelligencesquared.com or Tweet us @intelligence2. And if you’d like to get ad-free access to all Intelligence Squared podcasts, including exclusive bonus content, early access to new episodes and much more, become a supporter of Intelligence Squared today for just £4.99, or the equivalent in your local currency . Just visit intelligencesquared.com/membership to find out more.  Learn more about your ad choices.

Tim Marshall, a global affairs journalist and bestselling author, teams up with Helen Czerski, a renowned science communicator and physicist, to delve into the intricate relationship between geography and global politics. They discuss how geography shapes geopolitical conflicts, highlighting Russia's ambitions regarding Crimea and the strategic importance of regions like Taiwan. The conversation emphasizes the critical role of historical context in understanding current tensions and the influence of geographic factors on international relations and decision-making.

Dr. Helen Czerski, an oceanographer and physicist, and Dr. Justin Burton, a physicist focusing on giant bubbles and fluid mechanics, dive into the whimsical world of bubbles. They explore how to make colossal bubbles, including the feasibility of encasing the Earth. Fun anecdotes reveal NASA's role in bubble record-breaking and the chemistry behind stable bubbles. The duo also investigates bubbles in zero gravity as a potential climate solution, showcasing their vital role in oxygen absorption and carbon dynamics in oceans.

The podcast discusses Banksy's new mural in North London and the debate over deep-sea treasure hunting. They explore the environmental impact of mining valuable metals on the ocean floor, as well as Greenpeace's exclusion from an environmental forum. The episode also delves into historical analysis of whales' earwax records and ends with listener feedback and an interview recap.
