  • Chaos, COVID and Climate Change with Tim Palmer

    Chaos, COVID and Climate Change with Tim Palmer
    Oct 24 2022
    In his acclaimed latest book, The Primacy of Doubt: From Quantum Physics to Climate Change, How the Science of Uncertainty Can Help Us Understand Our Chaotic World, Professor Timothy Palmer argues that embracing the mathematics of uncertainty is vital to understanding ourselves and the universe around us. Whether we want to predict climate change or market crashes, understand how the brain is able to outpace supercomputers or find a theory that links quantum and cosmological physics, Palmer shows how his vision of mathematical uncertainty provides new insights into some of the deepest problems in science. The result is a revolution—one that shows that power begins by embracing what we don’t know. The Primacy of Doubt on Amazon: https://www.amazon.com/Primacy-Doubt-Quantum-Uncertainty-Understand/dp/1541619714 Timothy Palmer is the Royal Society Research Professor in Climate Physics, and a Senior Fellow at the Oxford Martin Institute at the University of Oxford. He is a mathematical physicist who has spent most of his career working on the dynamics and predictability of weather and climate. He pioneered the development of probabilistic ensemble forecasting techniques for weather and climate prediction, techniques that are now standard in weather and climate forecasting around the world. In 2021 Professor Palmer was awarded an honorary fellowship of the Institute of Physics. Professor Palmer was involved in the first five IPCC assessment reports, and was co-chair of the international scientific steering group of the World Climate Research Programme project (CLIVAR) on climate variability and predictability.

  • A Brief History of Time Nobel Prizewinner Bill Phillips

    A Brief History of Time Nobel Prizewinner Bill Phillips
    Oct 9 2022
    NIST Fellow William D. Phillips received the 1997 Nobel Prize in Physics “for development of methods to cool and trap atoms with laser light.” He shared the honor with Steven Chu and Claude Cohen-Tannoudji. Their work combined to create some of the most important technologies of modern atomic physics, which thousands of researchers worldwide employ today for a wide variety of applications. Today, he joins us to discuss time keeping throughout history and breakthroughs on the way to the best clocks ever made! Phillips began his experiments with laser trapping and cooling shortly after he arrived in 1978 at the National Bureau of Standards (the agency that became NIST), with the intent of creating a more accurate atomic clock. Several of his innovations in the following years became landmarks in the field. These included a device using a laser along with a magnetic field to decelerate and cool an atomic beam (the “Zeeman slower”); demonstrating the first device that trapped electrically neutral atoms (a magnetic trap); and measuring a temperature far below that predicted by the accepted theory of laser cooling at the time (known as sub-Doppler cooling).

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

    Part 2: Sir Roger Penrose & Stuart Hameroff: What is Consciousness?
    Aug 8 2022
    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.

  • The Elusive Higgs Boson: Frank Close

    The Elusive Higgs Boson: Frank Close
    Jul 13 2022
    Elusive: How Peter Higgs Solved the Mystery of Mass marks the 10th anniversary of the discovery of the Higgs Boson. On July 4, 2012, the announcement came that one of the longest-running mysteries in physics had been solved: the Higgs boson, the missing piece in understanding why particles have mass, had finally been discovered. On the rostrum, surrounded by jostling physicists and media, was the particle’s retiring namesake—the only person in history to have an existing single-particle named for them. Why Peter Higgs? Drawing on years of conversations with Higgs and others, Close illuminates how an unprolific man became one of the world’s most famous scientists. Close finds that scientific competition between people, institutions, and states played as much of a role in making Higgs famous as Higgs’s work did. Author of 20 books about science, Frank Close is Professor Emeritus of Theoretical Physics and Fellow Emeritus at Exeter College. He was formerly Head of the Theoretical Physics Division at the Rutherford Appleton Laboratory, vice President of the British Science Association, and Head of Communications and Public Understanding at CERN. He was awarded the Kelvin Medal of the Institute of Physics for his 'outstanding contributions to the public understanding of physics' in 1996, an OBE for 'services to research and the public understanding of science' in 2000, and the Royal Society Michael Faraday Prize for communicating science in 2013. He is the only professional physicist to have won a British Science Writers Prize on three occasions.

  • Nobel Prize Winner Adam Riess: The Hubble Tension is Getting WORSE!

    Nobel Prize Winner Adam Riess: The Hubble Tension is Getting WORSE!
    May 29 2022
    Chat with Nobel Prize winner Adam Riess about his team's newest measurements of the 'most important number in cosmology' the Hubble Constant. Using the Hubble Space Telescope for what it was meant to do, Adam's team continues to make ultra-precise measurements. We'll also explore the Hubble Tension, the future of Hubble now that the James Webb Space Telescope has deployed, and other cosmic conundrums. Adam is a brilliant teacher and a wonderful raconteur. Don't miss your chance to chat with a brilliant scientist about the most important topic in cosmology today! From the team: https://hubblesite.org/contents/news-releases/2022/news-2022-005 From CNN: Measuring the expansion rate of the universe was one of the Hubble Space Telescope’s main goals when it was launched in 1990. Over the past 30 years, the space observatory has helped scientists discover and refine that accelerating rate – as well as uncover a mysterious wrinkle that only brand-new physics may solve. Hubble has observed more than 40 galaxies that include pulsating stars as well as exploding stars called supernovae to measure even greater cosmic distances. Both of these phenomena help astronomers to mark astronomical distances like mile markers, which have pointed to the expansion rate. In the quest to understand how quickly our universe expands, astronomers already made one unexpected discovery in 1998: “dark energy.” This phenomenon acts as a mysterious repulsive force that accelerates the expansion rate. And there is another twist: an unexplained difference between the expansion rate of the local universe versus that of the distant universe right after the big bang. Scientists don’t understand the discrepancy but acknowledge that it’s weird and could require new physics. “You are getting the most precise measure of the expansion rate for the universe from the gold standard of telescopes and cosmic mile markers,” said Nobel Laureate Adam Riess at the Space Telescope Science Institute and a distinguished professor at the Johns Hopkins University in Baltimore, in a statement. “This is what the Hubble Space Telescope was built to do, using the best techniques we know to do it. This is likely Hubble’s magnum opus, because it would take another 30 years of Hubble’s life to even double this sample size.” Adam Guy Riess (born December 16, 1969) is an American astrophysicist and Bloomberg Distinguished Professor at Johns Hopkins University and the Space Telescope Science Institute. He is known for his research in using supernovae as cosmological probes. Riess shared both the 2006 Shaw Prize in Astronomy and the 2011 Nobel Prize in Physics with Saul Perlmutter and Brian P. Schmidt for providing evidence that the expansion of the universe is accelerating.
