Anna Dean and Professor Clarke Halloway
Where science meets the edge of human understanding.
Each week, media moderator Anna Dean and renowned physicist Professor Halloway sit down for an unfiltered deep dive into the ideas reshaping our world — from the mysteries of consciousness and the frontiers of quantum physics, to the explosive rise of artificial intelligence and the technologies redefining what it means to be human. This is not a surface-level conversation. This is science, philosophy, and curiosity — unleashed.
Topics discussed in depth: Ai, Conciousness, Quantum Immortality,Ghosts, NDEs, Quantum Computing, Reality and Freewill.
In today's Quantum Curiosities, Anna and Professor Halloway press on a wild idea: what if memories could be edited? The process of remembering is like recreating memories as we go. They explore the promise, the perils, and the profound questions raised by the thought of rewriting the past.
This week on Quantum Curiosities, Anna and Professor Halloway tackle what came before the Big Bang and what might lie beyond it. It's one of the biggest questions in cosmology: did everything truly begin 13.8 billion years ago, or is our universe just one chapter in a much stranger story? They dig into the theories, the unknowns, and why the beginning of everything might not be the beginning at all.
Today on Quantum Curiosities, Anna and Professor Halloway get into it over the limits of AI. These systems can do astonishing things, but where are the boundaries? They explore what AI genuinely can't do, where the hype outruns the reality, and why understanding the limits matters just as much as celebrating the breakthroughs.
This week on Quantum Curiosities, Anna and Professor Halloway discuss the brain as a prediction machine. Rather than passively taking in the world, your brain is constantly guessing what's about to happen, filling in gaps, anticipating outcomes, and updating its predictions as things develop. They dig into how this predictive machinery shapes everything from perception to decision-making, and what happens when the predictions go wrong.
Anna Dean and Professor Clarke Halloway tackle the oldest question in human history: why are we here? Instead of relying on pre-written cosmic scripts, they examine how the sheer improbability of the physical universe sets the stage for human existence. The conversation moves past the anxiety of an indifferent cosmos and challenges you to look at your life not as a passive accident, but as an active experiment. This episode of Quantum Curiosities and Tech Revelations breaks down the philosophical shift from searching for external validation to taking responsibility for your own purpose. You will hear why giving up on a grand, universal mandate is actually a liberating step. Meaning is not something you find waiting for you, but a structure you build yourself through your daily choices, relationships, and actions.
In this episode Anna and Professor Halloway discuss Midjourney's new Ultrasonic full body scanner technology. Midjourney's Ultrasonic CT scanner is the flagship product of Midjourney Medical, a healthcare division the AI-image-generation company launched in June 2026. It's a full-body imaging device that uses ultrasound instead of radiation or magnets — essentially a "whole-body ultrasound" that captures a scan in as little as 60 seconds. The system relies on ultrasound-on-chip technology (developed in co-operation with Butterfly Network) and a water-based coupling medium, aiming to deliver MRI-comparable imaging quality at a fraction of the cost, time, and complexity of traditional scanners. Midjourney has reportedly committed over $74 million to the effort. The company's vision is to make whole-body screening as casual as a trip to the spa: it plans to open its first "Midjourney Spa" in 2027, where patients would get a 60-second full-body scan without radiation exposure. The prototype was unveiled publicly in mid-2026 and has generated significant industry buzz, though it has also drawn skepticism from radiologists and medical professionals about whether ultrasound can truly match MRI-level diagnostic detail.
In this epiosode, Anna and Professor Halloway discuss various approaches to managing these alignment challenges, exploring technical solutions like reward modeling and interpretability, governance frameworks for deploying AI safely, and philosophical questions about how to encode human values into systems that may and seem to be on the verge of surpassing human-level intelligence in specific domains. AI Alignment is the critical endeavor to ensure that artificial intelligence systems pursue objectives that are genuinely aligned with human values, intentions, and ethical principles. As AI systems grow increasingly sophisticated and autonomous, the challenge extends beyond simply making them perform tasks correctly—it encompasses ensuring they interpret goals as humans intend them, avoid unintended harmful behaviors, and remain beneficial even as they scale in capability. The field addresses fundamental questions: How do we specify what we actually want? How do we prevent AI from pursuing goals in unexpected or dangerous ways? And how do we maintain meaningful human oversight as systems become more complex? The challenge becomes particularly acute with advanced AI systems that might optimize for objectives in ways humans didn't anticipate, or that might develop capabilities making them difficult to control or redirect. Misalignment can range from subtle issues—like a recommendation algorithm maximizing engagement at the cost of user well-being—to existential concerns about highly capable systems pursuing goals orthogonal or opposed to human flourishing.
This episode likely explores is the Libet effect: in the 1980s, neuroscientist Benjamin Libet had subjects flex their wrist whenever they felt the urge, while EEG tracked their brain activity. He found that a "readiness potential"; a buildup of neural activity in the motor cortex — fired roughly half a second before people consciously felt they'd decided to move. In other words, the brain appears to begin preparing a choice before we're aware of making it, which seems to demote conscious will from the cause of our actions to a kind of after-the-fact witness. This kicked off a decades-long free-will debate: some argue it proves free will is an illusion (we're just narrating what the brain already chose), while others counter that we may still have a "veto power" — the ability to consciously cancel a prepared action before it happens (Libet himself proposed this). More recent experiments have refined the picture, showing decision-related activity in the brain up to several seconds before choice in some cases, though critics point out the effect is strongest for trivial, spontaneous actions, not deliberate deliberation. Where the "quantum curiosities" angle comes in is the temptation to see quantum indeterminacy — true randomness at the subatomic level — as the loophole that rescues free will: if the brain amplifies quantum fluctuations, maybe our choices aren't fully determined by prior physical states. But physicists and philosophers usually respond with a dilemma: if a choice rides on quantum randomness, it's not free choice, just dice rolls — and either way, the conscious self still seems to arrive on the scene after the action has begun, not before. So the episode's takeaway is probably that the brain's "decision" unfolds earlier and more automatically than our inner sense of choosing suggests — a humbling mix of neuroscience, philosophy, and poorly little quantum sparkle.
The chatter around OpenAI's GPT-6 Astra has reached fever pitch. In this episode of Quantum Curiosities, hosts Anna and Professor Halloway cut through the hype to ask the question everyone's whispering: is this actually it — the moment artificial general intelligence stops being a phrase and becomes a thing? From Astra's real-time reasoning and multimodal fluency to the quiet benchmark numbers the press release glossed over, the pair dissect what a "general" intelligence would really need — and whether we're looking at a breakthrough, a very clever autocomplete, or something in between.
In this episode Anna and Professor Halloway examine the delayed-choice experiment. The delayed choice experiment demonstrates that a "wave or particle" is not a property of the photon alone, it's a property of the entire experiment, including choices made later. Nothing travels backward; the universe simply doesn't assign a definite wave/particle history to the photon until the full measurement context is fixed. It remains one of the most vivid (and misinterpreted) demonstrations of quantum weirdness — and a core reason quantum mechanics rejects naive realism about what's "really happening" between measurements.
Anna and Professor Halloway discuss Halloway's new science fiction book, The Keepers Of A Noble Breed. The discussion gets lively as Anna takes the opposing view that Professor Halloway intended as the writer of the book.
In this episode of Quantum Curiosities, we explore the fascinating intersection of acoustic physics, architecture, and human biology to investigate the real physical mechanics behind paranormal encounters. Centered around the paper "The 19Hz Frequency: The Physics of Perceived Apparitions," Anna and Professor Halloway break down how invisible environmental triggers, from insidious carbon monoxide leaks to inaudible, low-frequency sound waves known as infrasound, can hijack the human body. By examining landmark discoveries like Vic Tandy’s vibrating 19Hz laboratory fan and real-world experiments in subterranean spaces like Edinburgh's Mary King’s Close, this episode reveals how standing waves can literally vibrate our eyeballs to project shadowy optical illusions, spike our cortisol levels, and transform everyday rooms into accidental "ghost-making machines."
Welcome to this episode of Quantum Curiosities, where Anna and Professor Halloway examine the Many Worlds Interpretation of quantum mechanics. They explain how every atomic variation splits the universe into countless parallel physical states where all possible outcomes actually occur. You will hear how physicist Hugh Everett the Third originated this concept in the nineteen fifties, turning it into a major mathematical position in modern physics. The hosts break down the underlying mechanics using the wave function and the Schrödinger's cat thought experiment to show how reality separates without a mathematical collapse. The discussion then explores how quantum decoherence seals off these alternate realities permanently by reviewing a specific case study of Saturn's moon, Hyperion. You will learn how constant environmental interaction forces physical objects into definite paths in our specific version of reality. The episode also examines the direct impact this theory has on your personal identity, morality, and free will. Finally, Anna and the Professor cover David Deutsch's quantum computer thought experiment to demonstrate the physical reality of these multiple states and explain why human beings remain trapped in a single timeline.
Quantum Curiosities with Anna Dean and Professor Clarke Halloway invites you on a mind-bending journey into the nature of time itself. In this episode, they explore what it really means to look back in time—from the cosmic echoes of the early universe to the strange ways memory, observation, and quantum theory intertwine. Pull up a chair at the edge of spacetime as they blend storytelling, science, and speculation to ask whether the past is truly gone…or still quietly shaping our present.
Episode Intro Blurb In this episode of Quantum Curiosities, hosts Anna and Professor Halloway dive into the front lines of longevity science to explore whether we can actively roll back the biological clock. Unpacking Harvard geneticist David Sinclair’s Information Theory of Aging, the episode breaks down the radical idea that getting older isn't permanent physical wear-and-tear, but rather corrupted cellular software—scratches on our epigenetic instructions that can be buffed out using modified Yamanaka factors (OSK gene therapy). Balancing high-stakes science with essential skepticism, the hosts trace longevity research from the overhyped failures of resveratrol and NMN supplements to groundbreaking 2026 FDA-approved human clinical trials. From eye-stroke treatments governed by antibiotic safety switches to supercomputers screening billions of molecules for age-reversing pills, this episode examines what happens when geroscience shifts from science fiction to human reality—and weighs the massive economic, moral, and psychological implications of doubling the human healthspan.
In the latest episode of Quantum Curiosities and Tech Revelations, hosts Anna Dean and Professor Clarke Halloway delve into "The GLP-1 Gila Monster Venom and the Science Of Appetite." This episode explores the fascinating origins of transformative weight loss drugs, drawing connections to the Gila monster's venom, and critically examines their associated pros, cons, and the currently unknown long-term effects, offering listeners a comprehensive scientific overview of this rapidly evolving field.
What happens when making something more efficient actually makes us use more of it, not less? In this episode of Quantum Curiosities and Tech Revelations, we dive into Jevons' Paradox—the counterintuitive 19th-century economic principle originally observed with coal consumption—and explore its startling relevance to our AI-saturated present. As artificial intelligence makes computation, energy, and even human attention dramatically cheaper and more accessible, are we witnessing history repeat itself on a technological scale nobody quite anticipated? Join us as we unpack how efficiency gains in AI might be fueling unprecedented consumption rather than conservation, with consequences rippling across energy grids, data centers, and the very fabric of how we work and think. To help navigate this paradox, we're joined by Anna, whose sharp curiosity and knack for asking the questions everyone's thinking but nobody voices, and Professor Halloway, whose academic rigor and historical perspective ground our speculative leaps in solid reasoning. Together, they'll trace Jevons' Paradox from Victorian coal mines to modern GPU clusters, debating whether AI's relentless efficiency gains are steering us toward abundance or toward an entirely new category of resource anxiety. Expect sparks of disagreement, unexpected historical parallels, and a few uncomfortable questions about what "progress" really means when the tools themselves start consuming more than they save.
This episode introduces CRISPR, the gene-editing technology allowing scientists to make precise cuts in DNA using guide RNA and molecular scissors like Cas9. This conversation explores the vast potential of the technology, including the target treatment of genetic disorders like sickle cell anemia, the enhancement of crop resilience, and the engineering of T-cells to combat cancer. The discussion also details the profound challenges accompanying this science, such as accidental off-target edits and the creation of genetic mosaics. It raises critical ethical questions about the long-term societal impacts of altering the human genetic blueprint through germline editing, emphasizing the responsibility required as we step into this new era of biology.
In this episode of Quantum Curiosities and Tech Revelations, Anna and Professor Halloway take on one of the most unsettling questions in science and philosophy: are we really the authors of our choices, or is free will only a convincing illusion? Drawing from neuroscience, psychology, and the ideas of thinkers like Sam Harris and Robert Sapolsky, the conversation challenges the deeply held belief that we consciously control our thoughts and actions. As the episode unfolds, it explores what this idea means for morality, justice, guilt, pride, and compassion in everyday life. The Freewill Illusion is a thought-provoking journey into the hidden forces that shape human behavior, inviting listeners to rethink responsibility and imagine a more humane way of understanding ourselves and others.
In this episode of Quantum Curiosities and Tech Revelations, Anna and Professor Halloway explore why artificial intelligence inspires both awe and anxiety, separating the real capabilities of modern language models from the myths we project onto them. Their conversation unpacks how systems like ChatGPT can feel startlingly human while still operating as powerful pattern-recognition tools rather than true minds. Along the way, the episode examines big questions about data, creativity, jobs, manipulation, and whether society is building AI as a tool for human flourishing or drifting toward something far less accountable. The Promise of AI offers a thoughtful, accessible look at the future now taking shape, and why understanding the human choices behind these systems matters as much as the technology itself.
