Mathematics describes the real world of atoms and acorns, stars and stairs, with remarkable precision. So is mathematics invented by humans—like chisels and hammers and pieces of music? Or is mathematics discovered—always out there, somewhere, like mysterious islands waiting to be found? Whenever mathematics is will help define reality itself.

Featuring interviews with Roger Penrose, Stephen Wolfram, Max Tegmark, David Gross, and George Lakoff.

What is intelligence, and how is AI emergence a natural consequence of evolution? In his book "What Is Intelligence?" and in this conversation, Google's Blaise Agüera y Arcas takes up the idea that prediction is fundamental not only to intelligence and the brain but to life itself, and explores the wide-ranging implications. These include radical new perspectives on the computational properties of living systems, the evolutionary and social origins of intelligence, the relationship between models and reality, entropy and the nature of time, the meaning of free will, the problem of consciousness, and the ethics of machine intelligence.

Blaise Agüera y Arcas is a VP/Fellow at Google, where he is the CTO of Technology & Society, and the founder of Paradigms of Intelligence, an organization dedicated to fundamental AI research. He is the author of Who Are We Now?, and his research has included work on privacy-preserving machine learning, on-device AI, large language models, and human identity.

How do diverse religions/traditions treat the “person,” present status and afterlife future? Buddhism’s no self. Hinduism’s soul illuminating the mind. Prior lives in Eastern and African traditions. Body and soul, resurrection and judgment, in Abrahamic traditions.

The Ruliad is a term that Stephen Wolfram developed, which he describes as the entangled limit of everything that is computationally possible, the result of following all possible computational rules in all possible ways.

When the long-awaited day dawns and the aliens finally arrive on Earth, they might eat us and destroy the planet―or, just maybe, they might share the secrets of the Universe with us. When that time comes, will we be able to cross the communication barrier to beg for our lives? If the aliens do hold out those precious jewels of knowledge, will we even be able to grasp them? Professor Daniel Whiteson and Warner explode what we thought we knew about talking to our cosmic neighbors―and even science itself―by asking and answering questions both lighthearted and profound.

Whiteson's book, Do Aliens Speak Physics?: And Other Questions about Science and the Nature of Reality, is available for purchase now.

What happens after we die? Is there life after death? If so, what kind of life? From heaven and hell to systems and cycles of reincarnation, we explore Hinduism, Buddhism, Islam, Judaism, and Chinese traditions, as well as Christianity.

Featuring interviews with Hamza Yusuf, Carol Zaleski, Tao Jiang, Andrew Loke, and Yujin Nagasawa.
