TED-Ed YouTube Channel Teaser

Right now, somewhere out there, an educator is delivering a mind-altering lesson to their class. I want to engage your brains in this.

Chris Anderson: I tried to get my head around how vast our Earth is.

Logan Smalley: The lesson only reaches the students in that room. What would happen if we captured it? It's a toothed wheel.

LS: What if pro animators and visualization artists could bring that lesson to life?

CA: It's a common object that literally fits one million Earths. It's got a bunch of notches and a bunch of teeth. This was Fizeau's solution --

LS: When that lesson lands, curiosity is ignited.

CA: It seems impossibly big.

AS: Something interesting happens.

CA: In the great scheme of things, it's a pinprick.

AS: A door closes on the light beam that's coming back to his eye.

AS: He calculates the speed of light to within two percent of its actual value.

CA: The more you know, the more amazing the world seems. That's the central mission of TED-Ed: to capture and to amplify the voice of the world's greatest teachers. He does this in 1849.

CA: It's the crazy possibilities, the unanswered questions, that pull us forward. So stay curious.
