    Sabine Hossenfelder Gets Existential Without the Gobbledygook

    From renowned physicist and creator of the YouTube series “Science without the Gobbledygook,” a book that takes a no-nonsense approach to life’s biggest questions, and wrestles with what physics really says about the human condition
    Not only can we not currently explain the origin of the universe, it is questionable we will ever be able to explain it. The notion that there are universes within particles, or that particles are conscious, is as scientific, as is the hypothesis that our universe is a computer simulation. On the other hand, the idea that the universe itself is conscious is difficult to rule out entirely.
    According to Sabine Hossenfelder, it is not a coincidence that quantum entanglement and vacuum energy have become the go-to explanations of alternative healers, or that people believe their deceased grandmother is still alive because of quantum mechanics. Science and religion have the same roots, and they still tackle some of the same questions: Where do we come from? Where do we go to? How much can we know? The area of science that is closest to answering these questions is physics. Over the last century, physicists have learned a lot about which spiritual ideas are still compatible with the laws of nature. Not always, though, have they stayed on the scientific side of the debate.
    In this lively, thought-provoking book, Hossenfelder takes on the biggest questions in physics: Does the past still exist? Do particles think? Was the universe made for us? Has physics ruled out free will? Will we ever have a theory of everything? She lays out how far physicists are on the way to answering these questions, where the current limits are, and what questions might well remain unanswerable forever. Her book offers a no-nonsense yet entertaining take on some of the toughest riddles in existence and will give the reader a solid grasp on what we know—and what we don’t know.

    Part 2: Sir Roger Penrose & Stuart Hameroff: What is Consciousness?

    Part 2: Sir Roger Penrose & Stuart Hameroff: What is Consciousness?

    A conversation with Nobel Prize Winner and renowned mathematical physicist Sir Roger Penrose and anesthesiologist Dr. Stuart Hameroff about consciousness and quantum mechanics.
    Sir Roger Penrose and Dr. Stuart Hameroff have tackled one of the most vexing problems in science -- how does consciousness work? Their theories of consciousness were selected by the Templeton Foundation for study. We will discuss Is the brain a sophisticated computer or an intuitive thinking device? Following on from their conference in Tucson which pitted Integrated Information Theory (IIT) against Orchestrated Objective Reduction (Orch-OR), Sir Roger Penrose OM and Stuart Hameroff discuss the current state of theories that might explain human consciousness and objections to them from FQXI and others.
    Sir Roger Penrose describe examples of ‘non-computability’ in human consciousness, thoughts and actions such as the way we evaluate particular chess positions which cast doubt on ‘Turing’ computation as a complete explanation of brain function. As a source of non-computability, Roger discuss his ‘objective reduction’ (‘OR’) self-collapse of the quantum wavefunction which is a potential resolution for the ‘measurement problem’ in quantum mechanics, and a mechanism for non-computable physics.

    Dr. Stuart Hameroff reviews neuronal and biophysical aspects of Orch OR, in which ‘orchestrated’ quantum vibrations occur among entangled brain microtubules and evolve toward Orch OR threshold and consciousness. The nature, feasibility, decoherence times and evidence for quantum vibrations in microtubules, their role and correlation with consciousness, effects upon them of anesthetic gases and psychedelic drug molecules will be discussed, along with Orch OR criticisms and predictions of microtubule quantum vibrations as therapeutic targets for mental and cognitive disorders.

    Part 2 of 2: Quantum Physics and The End of Reality with Sabine Hossenfelder, Carlo Rovelli, and Eric Weinstein hosted by Brian Keating for the Institute for Art and Ideas

    Part 2 of 2: Quantum Physics and The End of Reality with Sabine Hossenfelder, Carlo Rovelli, and Eric Weinstein hosted by Brian Keating for the Institute for Art and Ideas

    We imagine physics is objective. But quantum physics found the act of human observation changes the outcome of experiment. Many scientists assume this central role of the observer is limited to just quantum physics. But is this an error? As Heisenberg puts it, "what we observe is not nature in itself but nature exposed to our method of questioning." In all our studies of reality and nature then, the observer plays a role -- not just in quantum physics.
    Should we recognize science can never access reality independent of the observer? Should we re-define science not as uncovering objective reality, but as uncovering the functions, limitations and structures of the mind of the observer themselves? And if we cannot remove the observer, might quantum physics help us to understand the observer - as Roger Penrose suggests consciousness "reeks of something quantum mechanical."
    Sabine Hossenfelder is a research fellow at the Frankfurt Institute for Advanced Studies, author of Lost in Math: How Beauty Leads Physics Astray and regular contributor to Forbes. She is known for her popular YouTube channel Science Without The Gobbledygook
    Eric Weinstein is an American podcast host, managing director of Thiel Capital, doctor of mathematical physics and member of the "intellectual dark web".
    Carlo Rovelli is an Italian theoretical physicist who works mainly in the field of Quantum Gravity. Carlo's popular science book Seven Briefs Lessons on Physics has been translated into 41 languages and sold over one million copies. In 2019 he was named one of the 100 most influential thinkers by Foreign Policy magazine.

Love this show

As an amateur, the show feeds my need for more knowledge and context, and it’s giving me better perspective and information than other sources. It’s challenging yet accessible. The only problem is that, as a newer subscriber, my reading list is growing faster as I catch up to all the content!

Exactly what I have been looking for

I am a biochemistry graduate but have always been fascinated and interested in physics. Dr. Keatings podcasts are exactly the level of science that I have been looking for in a podcast. Often times science podcasts are produced at the laypersons level or for a graduate student who is active in their field. I can follow about 95% of the podcast, and anything I do not understand I can look up and get an idea of what they’re discussing. I’d highly suggest the podcast for any chemistry undergraduate who is interested in physics, but doesn’t feel like cracking open a textbook to learn particle physics, cosmology, etc. Although, after listening to these podcasts, I found myself buying and reading textbooks anyways, because the information that I have been searching for finally feels accessible AND fun. Overall an excellent podcast. I’d highly recommend it.
