Some people call Jefferson our only scientist-President, and T.J. himself said that "Nature intended me for the tranquil pursuits of science, by rendering them my supreme delight." Here's the story of how Jefferson used science to help a young nation make its mark Check out the book "Mr. Jefferson and the Giant Moose" by Lee Dugatkin!!! http://amzn.to/1RMFScF Have an idea for an episode or an amazing science question you want answered?

Tweet ⇒ http://bit.ly/OKTBSsleep Share on FB ⇒ http://bit.ly/OKTBSsleepFB ↓ More info and sources below ↓ Why do we sleep? We spend a third of our lives in slumber, but science has yet to determine exactly why we have do it. Here’s a look at how sleep works, why we’re not getting enough sleep, what happens if you DON’T sleep, and an idea about where sleep came from in the first place.

    Why NASA Punched an Asteroid

    ↓↓↓ More info and sources below ↓↓↓ Where did life come from? It’s one of the biggest questions humans have ever asked — and the answer might be locked in ancient space rocks that were around before life began. To find out, NASA pulled off one of its most ambitious missions ever, landing on an asteroid and sending a rock sample back to Earth. Today, we’re going to take a look at what it brought back.

    Why Solar Eclipses Are Such a Big Deal

    Join our Patreon community: https://www.patreon.com/itsokaytobesmart SUBSCRIBE so you don’t miss a video! ►► http://bit.ly/iotbs_sub ↓↓↓ More info and sources below ↓↓↓ On April 8, 2024, the Moon’s shadow fell upon the Earth, creating a total solar eclipse across North America. If you had the chance to see it, you're surely glad you didn't miss it. It’s an amazing coincidence that total eclipses happen at all — and that we’re alive at a time when we can see and predict them. We made this video so you can learn how to watch an eclipse safely, what to look for during an eclipse, why eclipses happen, and how eclipses have helped advance scientific research.

    Why Are The Bees Dying?

    Viewers like you help make PBS (Thank you 😃) . Support your local PBS Member Station here: https://to.pbs.org/PBSDSDonate If bees go, will they take us with them? Subscribe: http://bit.ly/iotbs_sub Twitter: @jtotheizzoe @okaytobesmart ↓ More info and sources below ↓ Bees, wild and domesticated, are in big trouble. Bee colonies are dying off at alarming rates, and the cause isn't clear. Pesticides, habitat loss, disease… there's a laundry list of likely culprits.

    Which Came First - Flowers or Bees?

    Viewers like you help make PBS (Thank you 😃) . Support your local PBS Member Station here: https://to.pbs.org/PBSDSDonate Stop and smell the flowers… and watch this video Subscribe: http://bit.ly/iotbs_sub Twitter: @jtotheizzoe @okaytobesmart ↓ More info and sources below ↓ Bees and flowers have an amazingly close relationship. Flowers need bees in order to reproduce, and bees need flowers to feed their colonies. Take away one, and the other would disappear too. It begs the question: When it comes to evolution, which came first, the bees or the flowers?
