Atomic clocks are the most precise timekeepers ever built. If you could keep an advanced atomic clock running long enough, it would neither gain nor lose a single second over the entire lifespan of the universe. With the availability of spectrally pure lasers and the ability to precisely measure optical frequencies, it appears the era of optical atomic clocks has begun. Advances in atomic clocks are expected to be important in a range of emerging technological applications, including quantum computers. -
Tonight, the Perimeter Institute of Theoretical Physics in Waterloo, Ontario, will be hosting an extra special public lecture that will be streamed live via Discovery News. At 7 p.m. ET, 2012 Nobel Laureate in Physics David Wineland will delve into the "theoretical and technological know-how needed to build these ultra-precise timepieces," discussing how humanity is gaining a finer and finer grasp on time.
It's very rare to be in the audience with a Nobel Prize winner, but tonight you have your chance - Discovery News will be streaming Wineland's lecture LIVE. Simply bookmark this page and tune in at 7 p.m. ET tonight!
