From his article in National Geographic:
Most of us will never get to see nature’s greatest marvels in person. We won’t get a glimpse of a colossal squid’s eye, as big as a basketball. The closest we’ll get to a narwhal’s unicornlike tusk is a photograph. But there is one natural wonder that just about all of us can see, simply by stepping outside: dinosaurs using their feathers to fly.
Today, TEDxCERN and TED-Ed have unveiled the first of 5 animated lessons specially developed by CERN scientists for TEDxCERN and brought to life by the talented animators at TED-Ed: “The beginning of the universe, for beginners.”
The lesson, which you can watch above(!) and at ed.ted.com, was conceived by CERN physicist Tom Whyntie and explains how cosmologists and particle physicists explore questions like, “How did the universe begin? How is it expanding?” by replicating the heat, energy, and activity of the first few seconds of our universe, right after the Big Bang.
With the proliferation of digital photography, kids know about posing for photos, taking photos, and browsing photos on phones. But how much do they know about the history of photo technologies? This TED Ed video, Illuminating photography: From camera obscura to camera phone by Eva Timothy and Andy London, is a great primer.
