Right now, somewhere out there,

0:00:02.231,0:00:05.269
an educator is delivering[br]a mind-altering lesson to their class.

0:00:06.293,0:00:08.270
I want to engage your brains in this.

0:00:08.294,0:00:11.574
Chris Anderson: I tried to get[br]my head around how vast our Earth is.

0:00:11.598,0:00:14.753
Logan Smalley: That lesson only reaches[br]the students in that room.

0:00:14.777,0:00:16.578
What would happen if we captured it?

0:00:16.602,0:00:17.740
It's a toothed wheel.

0:00:17.764,0:00:20.251
LS: What if pro animators[br]and visualization artists

0:00:20.275,0:00:21.859
could bring that lesson to life?

0:00:21.883,0:00:24.908
CA: It's a common object[br]that literally fits one million Earths.

0:00:24.932,0:00:27.311
It's got a bunch of notches[br]and a bunch of teeth.

0:00:27.335,0:00:28.742
This was Fizeau's solution --

0:00:28.766,0:00:31.092
LS: When that lesson lands,[br]curiosity is ignited.

0:00:31.116,0:00:32.482
CA: It seems impossibly big.

0:00:32.506,0:00:34.136
AS: Something interesting happens.

0:00:34.160,0:00:36.591
CA: In the great scheme[br]of things, it's a pinprick.

0:00:36.615,0:00:40.626
AS: A door closes on the light beam[br]that's coming back to his eye.

0:00:40.650,0:00:43.209
LS: Then that group of students[br]is one thought closer

0:00:43.233,0:00:46.544
to being what every teacher[br]hopes their students will become:

0:00:46.568,0:00:47.569
a lifelong learner.

0:00:47.593,0:00:50.273
AS: Based on the distance[br]between the two stations --

0:00:50.297,0:00:53.217
CA: The quest for knowledge[br]and understanding never gets dull.

0:00:53.241,0:00:57.226
AS: He calculates the speed of light[br]to within two percent of its actual value.

0:00:57.250,0:01:00.645
CA: The more you know,[br]the more amazing the world seems.

0:01:00.669,0:01:02.679
That's the central mission of TED-Ed:

0:01:02.703,0:01:04.798
to capture and to amplify

0:01:04.822,0:01:06.840
the voice of the world's[br]greatest teachers.

0:01:06.865,0:01:09.659
He does this in 1849.

0:01:09.683,0:01:12.721
CA: It's the crazy possibilities,[br]the unanswered questions,

0:01:12.745,0:01:14.146
that pull us forward.

0:01:14.170,0:01:16.781
So stay curious.

0:01:20.211,0:01:23.804
TED-Ed is really an invitation[br]to teachers all around the world

0:01:23.828,0:01:25.336
to submit their best lessons.

0:01:25.360,0:01:28.594
Jordan Reeves: We review each submission[br]and work with the educators

0:01:28.618,0:01:32.260
to refine the lesson and make sure[br]that they're less than ten minutes long.

0:01:32.284,0:01:34.918
From there, we mail out[br]these portable recording booths.

0:01:34.942,0:01:36.808
A teacher pulls up their final lesson,

0:01:36.832,0:01:40.371
presses record and can instantly share it[br]with our animation team.

0:01:40.395,0:01:42.820
It's also an invitation to animators.

0:01:42.844,0:01:45.311
We are looking for talented animators

0:01:45.335,0:01:47.269
to get involved, submit their reels

0:01:47.293,0:01:49.939
and help us animate[br]these incredible lessons.

0:01:50.819,0:01:53.662
LS: Right now, there's a gifted educator[br]somewhere out there

0:01:53.686,0:01:55.380
delivering a life-changing lesson.

0:01:55.404,0:01:58.575
The TED-Ed team hopes that anyone[br]who is passionate about education

0:01:58.599,0:02:00.312
will help us find that teacher,

0:02:00.336,0:02:02.659
capture that moment and amplify it

0:02:02.683,0:02:05.013
the way that it deserves to be amplified.
