    A truly X-cellent and X-ceptional video… Join our Patreon community: https://www.patreon.com/itsokaytobesmart ↓↓↓ More info and sources below ↓↓↓ Despite being one of the rarest letters in English, the letter X is everywhere. We sign letters with it, we rate movies with it, we name all sorts of things after it. We’re kind of obsessed with it. And that’s probably all thanks to math, where X stands for the unknown. Let's explore the bizarre history of how X took on this role… References: https://sites.google.com/view/why-are-we-so-obsessed-with-x/home SUBSCRIBE so you don’t miss a video! ►► http://bit.ly/iotbs_sub ----------- High fives to all our Brain Trust Patrons: Charles Horton, Jr Holly, Brett, and Ashe Bullion Jaap Westera Millennial Glacier Mehdi Damou Barbora Bei Burt Humburg dani bowman David Johnston Baerbel Winkler Robert Young Eric Meer Karen Haskell Join us on Patreon! https://patreon.com/itsokaytobesmart Twitter http://www.twitter.com/DrJoeHanson http://www.twitter.com/okaytobesmart Instagram http://www.instagram.com/DrJoeHanson http://www.instagram.com/okaytobesmart Merch https://store.dftba.com/collections/its-okay-to-be-smart Facebook https://www.facebook.com/itsokaytobesmartpbs/​

    This Is Where New Ideas REALLY Come From

    Check out Hungry Planet on @pbsterra https://youtu.be/uH2jWc9TEVM ↓↓↓ More info and sources below ↓↓↓ The idea of the lone genius creating everything isn’t just misleading.

    Why Some of the Rainbow is Missing

    We’re on PATREON! Join the community: https://www.patreon.com/itsokaytobesmart ↓↓↓ More info and sources below ↓↓↓ Over 200 years ago, scientists were looking at sunlight through a prism when they noticed that part of the rainbow was missing. There were dark lines where there should have been colors. Since then, scientists have unlocked the secrets encoded in these lines, using it to uncover mind-boggling facts about the fundamental nature of our universe and about worlds light-years away.
