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.

TED-Ed is really an invitation
to teachers all around the world

to submit their best lessons.

We review each submission
and we work with the educators

to refine the lesson and make sure
that they're less than ten minutes long.

From there, we've got
these portable recording tools.

A teacher posts their final lesson,

presses record and can instantly share
with our animation team.

It's also an invitation to animators.

We are looking for talented animators

to get involved, submit their reals

and help us animate
these incredible lessons.

Right now, there's a gifted educator
somewhere out there

delivering a life-changing lesson.

The TED-Ed team hopes that anyone
who is passionate about education

will help us find that teacher,

capture that moment and amplify it

the way that it deserves to be amplified.
