“In Our Nature” is a NEW special limited series on It’s Okay To Be Smart!
We’re on PATREON! Join the community ►► https://www.patreon.com/itsokaytobesmart
↓↓↓ More info and sources below ↓↓↓
Seemingly distant ecosystems, even half a world apart, are connected in surprising ways. In this special limited series, Emily Graslie and Trace Dominguez join me as we explore the universal rules of life that tie together Earth’s living systems. In episode 3, we look at ecosystems at their largest and smallest scales of time and size from the Serengeti to Andrews Experimental Forestin Oregon. How does the cycling of nutrients and molecules make life possible on Earth? Who are these recyclers and scavengers? Sometimes this recycling happens fast and violently, and sometimes it happens slow and beautifully.
In Our Nature is a special miniseries produced by It’s Okay To Be Smart for PBS. Stay tuned for more episodes coming this summer, here on our YouTube channel!

Sometimes it's cold outside. But what if I told you that "cold" isn't real? There's no substance or quantity called "cold" in science. We can't measure the amount of "cold" in something. Instead it's about what's NOT there. In this week's video, learn the difference between heat and temperature, why a wind makes us feel colder, and what it's like to live as a mass of jiggling atoms.

The first thing a baby giraffe experiences after being born is a 2 meter fall straight down to the ground. But within an hour, it’s standing, walking, and nursing on its own. And a blue whale calf, after nearly a year growing inside mom, can swim to the surface moments after being born. Human babies on the other hand? We’re born unable to move or eat on our own, we can’t communicate or fully sense our world, and we leak EVERYWHERE. If humans are so smart, why are our babies so… un-smart? You may think it’s all about head size, but the real science is more complex.
