Hear the latest news about everything from quantum computers to astrophysics, all straight from scientists at the University of Maryland. Relatively Certain is produced by the Joint Quantum Institute and hosted by a rotating cast, featuring Chris Cesare, Emily Edwards and Sean Kelley. Episodes from Quantum Conversations, a prior series focused entirely on quantum physics, will remain available under the new name.
||CleanThe Nobel Prize: A LIGO Q&A||A little more than a hundred years ago, Albert Einstein worked out a consequence of his new theory of gravity: Much like waves traveling through water, ripples can undulate through space and time, distorting the fabric of the universe itself. Today, Rainer Weiss, Barry C. Barish and Kip S. Thorne were awarded the 2017 Nobel Prize in Physics for decades of work that culminated in the detection of gravitational waves in 2015—and several times since—by the Laser Interferometer Gravitational-Wave Observatory (LIGO).Emily and Chris sat down with UMD physics professor Peter Shawhan, a member of the LIGO collaboration, to learn more about gravitational waves and hear a sliver of the story behind this year's Nobel Prize.This episode of Relatively Certain was produced by Chris Cesare and Emily Edwards. It features music by Dave Depper.

||CleanLong live MATHUSLA||More than 300 feet underground, looping underneath both France and Switzerland on the outskirts of Geneva, a 16-mile-long ring called the Large Hadron Collider (LHC) smashes protons together at nearly the speed of light. Sifting through the wreckage, scientists have made some profound discoveries about the fundamental nature of our universe.But what if all that chaos underground is shrouding subtle hints of new physics? David Curtin, a postdoctoral researcher at the Maryland Center for Fundamental Physics here at UMD, has an idea for a detector that could be built at the surface—far away from the noise and shrapnel of the main LHC experiments. The project, which he and his collaborators call MATHUSLA, may resolve some of the mysteries that are lingering behind our best theories.This episode of Relatively Certain was produced by Chris Cesare, Emily Edwards, Sean Kelley and Kate Delossantos. It features music by Dave Depper, Podington Bear, Broke for Free, Chris Zabriskie and the LHCsound project.

||CleanLabs IRL: Boxing up atomic ions||What makes a university physics lab tick? Sean Kelley grabs a mic and heads to a lab that's trying to build an early quantum computer out of atomic ions. Marko Cetina and Kai Hudek, two research scientsts at the University of Maryland who run the lab, explain what it takes to keep things from burning down and muse about the future of quantum computers.This is the first installment of Labs in Real Life—Labs IRL, for short—a recurring segment on Relatively Certain that will explore what it's actually like to work in a university lab. (The work in this lab is supported by the Intelligence Advanced Research Projects Activity (IARPA) LogiQ Program through the U.S. Army Research Office.)This episode of Relatively Certain was produced by Sean Kelley, Emily Edwards and Chris Cesare. It features music by Dave Depper, dustmotes and Podington Bear.

||CleanThe limits of computation||Modern computers, which dwarf their forebears in speed and efficiency, still can't conquer some of the hardest computational problems. Making them even faster probably won't change that.Computer scientists working in the field of computational complexity theory explore the ultimate limits of computers, cataloguing and classifying a universe of computational problems. For decades, they’ve been stuck on a particular nagging question, which boils down to this: What’s the relationship between solving a problem and checking your work?Chris Cesare teams up with Emily Edwards and QuICS postdoctoral researcher Bill Fefferman to explain what this question entails and how researchers are tackling it with tools from physics.This episode of Relatively Certain was produced and edited by Chris Cesare, with contributions from Emily Edwards, Sean Kelley and Kate Delossantos. It features music by Dave Depper, Podington Bear, Kevin MacLeod and Little Glass Men.

||CleanJQI Podcast Episode 12||In our own galaxy and beyond, violent collisions fling a never-ending stream of stuff at the earth, and astrophysicists are eager to learn more about the processes that produce this cosmic barrage.Researchers from around the world have teamed up to build the High-Altitude Water Cherenkov (HAWC) gammy-ray observatory, an array of hundreds of huge water tanks on a mountain in Mexico. HAWC helps astrophysicists spot active cosmic neighborhoods by capturing the shower of particles created when high-energy packets of light smash into the earth’s atmosphere.Jordan Goodman, HAWC’s lead investigator, and Dan Fiorino, a postdoctoral researcher at UMD, tell Chris Cesare about the details of the HAWC experiment and how it promises to fill some gaps in our understanding of the universe. To learn more about HAWC, please visit www.hawc-observatory.org. The collaboration is preparing to publish the first results of its search, and you can read about the details in an upcoming source catalog or a paper about high-energy gamma rays from the Crab Nebula.This episode of Relatively Certain was produced by Chris Cesare, Sean Kelley and Emily Edwards and edited by Chris Cesare and Kate Delossantos, featuring music by Dave Depper, Podington Bear, Kevin MacLeod and Chris Zabriskie.

||CleanJQI Podcast Episode 11||This past March, NIST Fellows Joseph Reader and Charles Clark co-authored an article in Physics Today: "1932, a watershed year in nuclear physics."In a small detour from our typical quantum conversation, Charles sat down with Phil to recount some remarkable nuclear physics discoveries made that year. This podcast details the search for an isotope of hydrogen, culminating in the discovery of deuterium (heavy water).||10/30/2013||Free||View in iTunes|

As a layman fan (with a layman's understanding) of quantum physics, I find these podcasts enlightening and educational while being comprehensible to my afore mentioned layman's mind. Now I have to go lookup 'layman' to make sure I used it correctly. :-)
Fascinating and Informative
Good science, but pitched at freshman high school level. I wish it would present some stories at a collegiate level.
BTW Glad to see you back!
