Radiolab host Lulu speaks with 28-year-old Gazan physicist Qasem Walid about how quantum physics has become both a language and an inner refuge for him while living through war, displacement, and loss in Gaza. Over months of conversations, he describes daily life under bombardment, the deaths of his professor and relatives, and his experience of feeling like Schrödinger's cat-trapped in a box where his survival is uncertain and unseen by the outside world. He uses concepts like superposition, quantum tunneling, and harmonic oscillators to make sense of his own existence and to plead for the world to "open the box" and truly look at what is happening in Gaza.
Josh and Chuck discuss "third man syndrome," a phenomenon where people in extreme, often life-threatening situations report sensing a distinct, guiding presence that feels like another person with them. They explore classic accounts from Ernest Shackleton's Antarctic expedition, mountaineers like Frank Smythe and Joe Simpson, and survivors of the 9/11 attacks, then consider possible explanations ranging from an innate survival mechanism to the bicameral mind hypothesis. The conversation stays grounded in reported experiences while acknowledging that science has no definitive explanation yet.
Host Elise Hu introduces philosopher, bioethicist, and clinical psychologist Claudia Pasos-Ferreira, who explores when and how consciousness begins in human life. Drawing on recent neuroscience and developmental psychology, Pasos-Ferreira argues that newborns, and possibly late-term fetuses, display brain signatures associated with conscious perception and attention. She discusses the ethical implications of this evidence for medical practice and debates around personhood, and concludes with a broader reflection on consciousness as a "flame of awareness" shared across life and potentially machines.
The host brings together three thinkers-an atheist/agnostic philosopher, a Christian apologist, and a Hindu-trained psychiatrist and spiritual practitioner-to explore why so many people today report a lack of meaning and purpose. They debate whether purpose is objective or purely subjective, how religion, spirituality, neuroscience, trauma, technology, and social conditions contribute to a "meaning crisis," and whether any worldview can adequately address deep suffering such as children dying of cancer. Alongside high-level philosophical disagreement, they also discuss concrete psychological tools and spiritual practices that can help individuals move from feeling lost to experiencing more direction and purpose in their own lives.
Host Elise Hu introduces a favorite TED Talk by journalist and podcast host Shankar Vandantam about how poorly we understand our future selves. Through personal anecdotes, a powerful medical case, and the Ship of Theseus thought experiment, Vandantam argues that our identities and preferences change far more than we expect, creating an "illusion of continuity." He closes with three recommendations-stay curious, practice humility, and be brave-to better relate to and care for our future selves.
