    Who decides how long a second is? - John Kitching

    Discover how scientists developed atomic clocks, which use the vibrations of atoms to measure and maintain a globally consistent time. --In 1967, researchers gathered to answer a long-running scientific question: just how long is a second? It might seem obvious at first. A second is the tick of a clock, the swing of a pendulum, the time it takes to count to one. But how precise are those measurements? And what is that length based on? John Kitching digs into how we scientifically define this fundamental unit of time.Lesson by John Kitching, directed by Tjoff Koong.Support Our Non-Profit Mission----------------------------------------------Support us on Patreon: http://bit.ly/TEDEdPatreonCheck out our merch: http://bit.ly/TEDEDShop----------------------------------------------Connect With Us----------------------------------------------Sign up for our newsletter: http://bit.ly/TEDEdNewsletterFollow us on Facebook: http://bit.ly/TEDEdFacebookFind us on Twitter: http://bit.ly/TEDEdTwitterPeep us on Instagram: http://bit.ly/TEDEdInstagram----------------------------------------------Keep Learning----------------------------------------------View full lesson: https://ed.ted.com/lessons/who-decides-how-long-a-second-is-john-kitchingDig deeper with additional resources: https://ed.ted.com/lessons/who-decides-how-long-a-second-is-john-kitching#digdeeperAnimator's website: http://greenhouseanimation.com/directors/tjoff-koong/----------------------------------------------Thank you so much to our patrons for your support!

    Dig into the animal kingdom’s capacity for generosity, and find out how cooperation between animals may contribute to their survival.--Charles Darwin introduced the notion of “survival of the fittest,” where the fittest animals are those who can survive long enough to produce healthy offspring.
