Relatively Certain

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.

There’s a big unsolved mystery in physics: The cosmic balance sheet for matter in our universe just doesn’t add up. Galaxies all over space move as though they are much heavier than they appear. Scientists postulate that they are full of stuff we cannot see, stuff that they call dark matter.

TQW looks at recent research in the weird world of "ultracold" chemistry, where scientists have just discovered that chemical reactions can occur at only a few billionths of a degree above absolute zero.

A discussion of one of the most eerie aspects of quantum mechanics -- the utter randomness of measurements -- with guest Dr. Chris Monroe of JQI.

A primer on the fundamental terms and concepts of quantum information science, with guest Dr. Carl Williams, Chief of the Atomic Physics Division at the National Institute of Standards and Technology.
