Into the Impossible With Brian Keating

Physicists Missed These Particle Tracks for Decades (ft. Daniel Whiteson)Please join my mailing list here 👉 https://briankeating.com/yt to win a meteorite 💥 From the electrifying environment of high-speed particle collisions to the challenge of sifting signals from heaps of experimental noise, you'll hear how Prof Whiteson and his team are pushing boundaries. They discuss bold new algorithms capable of spotting non-standard tracks—think wild trajectories that defy classical expectations and could reveal surprises nature has kept hidden. Practical questions about detector design, efficiency, and even the mathematics of “smooth” particle paths make for a rich, dynamic dialogue. If you’re curious about how physicists ask the universe its most challenging questions, the frustrations and breakthroughs of innovation, and the fascinating interplay between theory and experiment, this episode will take you to the front lines of discovery. Plus, hear how machine learning might help us find not just the next weird particle, but perhaps the next Nobel-worthy revelation. Get ready for a fascinating journey into the impossible! Daniel Whiteson is a physicist whose research spans a wide range of topics at UC Irvine. By day, he works on the ATLAS experiment, one of the major physics collaborations at the Large Hadron Collider, where he contributes to Higgs boson precision measurements and develops advanced techniques in machine learning, data acquisition, and trigger systems. His research group is known for applying machine learning innovations to physics problems, including projects beyond ATLAS—like using approximate symmetries or jet pattern matching. Recently, his team has been focused on machine learning projects to identify unusual particle tracks, always pushing the frontier between physics and data science.

I Went From Stonehenge to the SKA: 5,000 Years of Cosmic Curiosity In 45 minutesPlease join my mailing list here 👉 https://briankeating.com/yt for your chance to win a meteorite 💥 What connects a 5,000-year-old stone circle to the most ambitious radio telescope ever built? In this episode, we travel from Stonehenge to Jodrell Bank and the Square Kilometre Array (SKA) to trace humanity’s obsession with the sky — from lifting megaliths to catching whispers of the Big Bang. We start at Stonehenge, a Neolithic “star clock” aligned with the solstices, then fast-forward through millennia to stand beneath the 76 m Lovell Telescope at Jodrell Bank, and finally into the control rooms of the SKA: hundreds of dishes and over 100,000 antennas designed to detect the first stars and galaxies. The tools change — stones, steel, superconducting detectors — but the question stays the same: what is our place in the universe? Topics: * How Neolithic builders engineered and aligned Stonehenge with the Sun? * Why Jodrell Bank became a Cold War–era listening post and a pulsar powerhouse? * How pulsars, neutron stars, and the Crab Nebula became cosmic calibration tools? * What the SKA will actually “hear” from the cosmic Dark Ages and first stars? * How the Simons Observatory and SKA together will rewrite our map of the cosmos Timestamps: 00:00 Stonehenge introduction and the mystery of its construction 01:56 Transport and engineering of the Sarsen and bluestones 05:34 Stonehenge as a solar-aligned cosmic calendar 08:00 Transition from Stone Age to modern astronomy at Jodrell Bank 09:15 Lovell Telescope history and its role in tracking Sputnik 20:00 Overview of the SKA and its global scientific mission 44:23 From ancient stones to radio telescopes: the shared human quest to understand the cosmos Thanks to the incredible staff of Jodrell Bank for their hospitality!
