Right now, somewhere,
an educator is delivering a mind-altering lesson to their class.
I want to engage your brains in this.
Chris Anderson: I tried to picture how vast our Earth is.
Logan Smalley: The lesson only reaches the students in that room.
What would happen if we captured that lesson?
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.
Fizeau's solution...
LS: When that lesson lands, curiosity is ignited.
CA: It seems impossibly big.
CA: In the great scheme of things, it's a pinprick.
Adam Savage: A door closes on the light beam
that's coming back to his eye.
LN: Then that group of students is one talk closer
to being what every teacher hopes their students will become:
a life-long learner.
AS: Based on the distance between the two stations...
CA: The quest for knowledge and understanding never gets dull.
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 greatest teachers.
He does this in 1849.
CA: It's the crazy possibilites, the unanswered questions,
that pull us forward.
So stay curious.
