Math may be the language of the universe, and brilliant minds and technology may have unlocked many of the secrets of the universe. But the pursuit of knowledge and insight always starts with the same thing: curiosity. Asimina Arvanitaki, a groundbreaking researcher with the Perimeter Institute for Theoretical Physics in Waterloo, Ont., reprises a talk she recently gave in her native Greece about the role of curiosity has played in the history of scientific discovery and in her own passion for science. And, in a wide-ranging onstage interview with Nahlah Ayed, she discusses the importance of fundamental research, the responsibilities of scientists to the public, and the appropriate role of AI in scientific research.

The narrative follows the evolution of background music from a radical artistic experiment into a deliberate corporate tool used to influence consumer behavior and workplace productivity. The episode examines the rise of Muzak and modern commercial programming, tracing how Satie's legacy transitioned from a satirical concept to the ubiquitous ambient sound found in modern commerce.

What's for dinner in 2050?

This episode explores the unsustainable nature of the modern global food system, examining how industrial agriculture and the rise of ultra-processed foods drive biodiversity loss, environmental degradation, and global health crises. The discussion highlights how corporate interests and political deregulation have prioritized profit and convenience over nutrition and traditional culinary heritages. The conversation also investigates potential solutions, ranging from technological innovations like lab-grown meat and plant-based alternatives to a return to flavor-focused, regenerative agriculture. While debating the tension between industrial efficiency and artisanal sustainability, the episode concludes that solving the climate and nutritional crises may be possible by bridging the investment gap in organic R&D and prioritizing food quality.
