Professor Meghan Gray discusses space co-ordinates and what sits at position 0,0 in the sky? More links and info below ↓ ↓ ↓ From Prof Gray: “Mea culpa dear viewers - as rightly pointed out by several commenters, the pinch point of the analemma is not where the equinox occurs. Instead it will be at the midpoint between the top and bottom. Thanks for the correction: happy to set the record straight in the service of science!” More videos with Professor Gray: http://bit.ly/Meghan_Playlist Professor Gray at the University of Nottingham: https://www.nottingham.ac.uk/physics/people/meghan.gray Some of Brady's other channels: https://www.youtube.com/numberphile https://www.youtube.com/deepskyvideos https://www.youtube.com/objectivityvideos https://www.youtube.com/periodicvideos https://www.youtube.com/channel/UCkIRMZDOKKKs-d14YPmLMxg (Unmade Podcast) Patreon: https://www.patreon.com/sixtysymbols The station/buoy at 0,0 at sea: https://www.ndbc.noaa.gov/station_page.php?station=13010 This project features scientists from The University of Nottingham http://bit.ly/NottsPhysics We're on Facebook at http://www.facebook.com/sixtysymbols And Twitter at http://twitter.com/sixtysymbols Sixty Symbol videos by Brady Haran and James Hennessy http://www.bradyharanblog.com Email list: http://eepurl.com/YdjL9
