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 Dina Genkina. Episodes from Quantum Conversations, a prior series focused entirely on quantum physics, will remain available under the new name.
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. Relatively Certain is a production of the Joint Quantum Institute, a research partnership between the University of Maryland and the National Institute of Standards and Technology, and you can find it on iTunes, Google Play or Soundcloud.
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 scientists 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.)

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.

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.
This past March, NIST Fellows Joseph Reader and Charles Clark co-authored an article in Physics Today: "1932, a watershed year in nuclear physics."
Phil Schewe discusses quantized energy levels with Steve Rolston (JQI) and Wes Campbell (former JQI postdoc and current UCLA professor).
Can you see a single photon? Does it weigh anything? Emily Edwards talks to Alan Migdall, an expert on single photon technology. Part 2 of three installments on photons.
Phil Schewe discusses how matter, such as atoms and electrons, can display wave-like properties. Steve Rolston describes early scattering experiments.
Emily Edwards and guests Steve Rolston and Alan Migdall talk about the history of the photon. Photons sometimes behave both like particles and waves. The nature of light has intrigued scientists for centuries.
Solving the mystery of blackbody radiation brings on the quantum revolution. Phil Schewe, Emily Edwards, and Steve Rolston discuss this pivotal moment for modern physics. 2006 Nobel Prize laureate John Mather discusses how his work relates to blackbody radiation.
