Introducing TED-Ed: Lessons Worth Sharing

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.
