A New Measure: The Revolutionary Quantum Reform of the Modern Metric System

<description>At the beginning of the 20th century, Einstein changed the way we think about time.  Now, early in the 21st century, the measurement of time is being revolutionized by the ability to cool a gas of atoms to temperatures millions of times lower than any naturally occurring temperature in the universe.  Nobel Prize recipient William Phillips, Ph.D., a Distinguished University and College Park Professor of Physics at the University of Maryland, talks about laser cooling and ultracold atoms and how they relate to time.

Atomic clocks, the best timekeepers ever made, are one of the scientific and technological wonders of modern life.  Such super-accurate clocks are essential to industry, commerce, and science; they are the heart of the Global Positioning System (GPS), which guides cars, airplanes, and hikers to their destinations.  Today, the best primary atomic clocks use ultracold atoms.   Series: "UC Berkeley Graduate Lectures" [Science] [Show ID: 37727]</description>

<description>With Amazon's Alexa spying on her owners, a massive data breach masterminded by Cambridge Analytica, and evidence of election interference promulgated by Facebook, tech policy has never had more significant implications for our society and democracy. Roger McNamee—noted tech venture capitalist, early mentor to Mark Zuckerberg, and Facebook investor—talks with Henry Brady, Dean of the Goldman School of Public Policy at UC Berkeley, about how he came to realize the serious damage that Facebook and other social media giants are doing and how he has committed to try to stop them.
