Inside The Most Precise Atomic Clock in the World I Motherboard

Published on Oct 4, 2018
From his basement lab in Boulder, Colorado, physicist Jun Ye and his team have built the world’s most precise atomic clock. The clock is so powerful it can measure otherwise imperceptible changes in the physical world. “Have you ever seen the movie called Interstellar? You’ll see some of that in our lab, it’s not science fiction. You can actually see clocks slow down,” explains Ye. In episode seven of The Most Unknown, geobiologist Victoria Orphan travels to JILA—a physics institute jointly operated by the University of Colorado Boulder and NIST—to untangle questions of space and time with Ye and his otherworldly atomic clock.

Mass Separation: Crash Course Engineering #17

Published on Sep 13, 2018
It can be really important to separate out chemicals for all kinds of reasons. Today we’re going over three different processes engineers use to achieve that separation: distillation, which separates substances based on their different boiling points; liquid-liquid extraction, which uses differences in solubility to transfer a contaminant into a solvent; and reverse osmosis, which filters molecules from a solvent by pressurizing it through a semipermeable barrier.
