NEW PODCAST EPISODES
Testing Time: Quantum physicists Fabrizio Piacentini and Laura Knoll discuss their recent experiment testing the predictions of Constructor Theory, a new meta-framework of physics that may encompass all other theories. The new framework could solve the mystery of why time marches in only one direction, even though the microscopic laws of physics are reversible. With Logan Chipkin
Happy Higgs-versary! Particle physicist Kevin Black tells Zeeya Merali about the LHC's new quest. Also, time-travel at the LHC, an update on the W Boson tests with Frank Wilczek; Catalina Curceanu on testing the origin of consciousness; & Queensland physicists are building quantum clocks.
Time's Arrow: A conversation with Paul Davies about time's irreversible flow, black holes, memories of Stephen Hawking and the information paradox, Maxwell's demon and living systems -- and how to improve universities. With Logan Chipkin.
