00:00Life, life, life, life, life, life
00:06And here is life, beautiful life, eager to blossom.
00:13The world invites us to new dawns.
00:19He gives us tears, singing hands
00:23And the sun that dazzles us
00:27The crisp air delights us
00:31It fills us with joy and life
00:34Life, life, life, life, life, life, life, life
00:41Life, life, life, life
01:14The eye, an extension of the brain, is its main tool for observing the outside world.
01:32Decomposed to be transmitted by optical energy, the perceived image will be materialized by the brain.
01:57Hello, light is me, well, it's us, and yes, it's true, I am a photon, l
02:02'Unit of light, a real puzzle for scientists.
02:06And I am a particle, good luck to anyone who can understand that, plus I carry energy, of course, which
02:16Light means energy.
02:18We mustn't forget that because, now I, great, an electron, that's a particle of
02:25'Electricity and light, I'm going to excite it a little.
02:28Hop!
02:36Wait !
02:39An electron in an excited state is full of energy! Fun, isn't it?
02:54I'm thinking!
02:56No, you misunderstood me, I mean, I'm thinking. Do you want to see?
03:02Well, anyway, that's why you see everything I touch.
03:07And then, importantly, yes, I'm the fastest in the world. Look!
03:14There you go! Not bad, huh? And that's nothing. 300,000 km per second, 7 times
03:20and a half times the circumference of the Earth in one second.
03:22That's my cruising speed. Who can do better? Nobody? No? Nobody?
03:28So, are you applauding me?
03:35I got you good, didn't I? I can't just leave like this without you.
03:38introduce the others.
03:40We, the photons, are countless.
03:49Our warmth and our light are the source of all life.
03:55Without us, your world would be a desert, a dead planet like so many others.
04:01And it would be grey because we also provide the colour.
04:16Mom, come and see. Isn't that butterfly beautiful!
04:19Tell me, Mom, why does the butterfly have such beautiful colors?
04:29Hey, do you realize? He can't even see us.
04:32Ah, that surprises me! Look!
04:47So, did you see that? I could have touched it.
04:49I'm going to say, it's unbelievable, really.
04:51And yet, it's us he sees. I would add that he sees only us.
05:02...
05:18Blurry images.
05:20Your eye is not properly adjusted to the distance of the object, look.
05:23Give instructions to the saw muscles to check the tension of the lens.
05:27And you, give orders to the internal and external rectus muscles
05:31to turn the eye laterally half a degree to the right.
05:47It's crazy how many people are being locked up, I tell you. What are we waiting for to lock them up?
05:50?
06:02It's crazy how many people are being locked up, I tell you. What are we waiting for to lock them up?
06:06?
06:11Oh, but that's not true!
06:19Well, there's no question of taking a breather, it seems.
06:22I suspect it's for the sawmill muscle since that's our area of expertise.
06:25I didn't try.
06:25We even add that we do nothing but that, and it's not easy, believe me.
06:28Can I speak?
06:29Me again, but we only hear from you here.
06:32There was no point in me running around like a madman, you know, it's not relaxing at all, is it?
06:35plus our job.
06:35We're not getting much help, and while we're wasting time discussing things, up there, he's seeing things blurry.
06:40Okay, lens tension adjustment, saw muscle, traction, force 5. Ok.
06:52Not the tension of money.
06:52Yes, it's not cool.
06:54Yes, it's not cool.
06:58Yes, it's not cool.
07:00He's not cool.
07:01He's not cool.
07:02No, not enough time.
07:03That's not good.
07:04That's not good.
07:05What don't you know?
07:08But fine, because you want to.
07:10If we're not good, it's not a problem, it's this one.
07:17And would you please comply with the instructions below?
07:21Come on, guys, we have to go.
07:48But what on earth is going on? What are they doing?
07:51Half a degree to the right for the internal and external rectus muscles.
07:55But that's precisely what we taught them, isn't it?
07:58Everyone is entitled to a small error in judgment, right?
08:01Ah, correction.
08:02Okay, adjusting the field of vision, internal and external rectus muscles, one tenth of a degree.
08:08Left, very good, left.
08:09We still need to know what they want, right?
08:12So, a tenth of a degree to the left, execute.
08:15Here, take this. My day is over. Bye.
08:18No, but that's not right, is it? Have you seen what time it is? And
08:21All the work?
08:22That's not my problem.
08:24Alright.
08:28Nothing!
08:31Nothing!
09:51So, master, are we keeping up the good work?
09:53With such beautiful sunshine, it can only be milk.
09:56Carotenes, but I don't see them, you know.
09:58We're going to need it in the sector, though.
10:00There ?
10:00Ah, that's good, here they are.
10:10Come on !
10:15Come on !
10:18Come on !
10:19Ah, they're young. In any case, they're in good shape.
10:26Who is that? What is it used for?
10:27What, you don't know about vitamins?
10:29Ah, vitamins, you can believe me.
10:31Without them, the world would not be what it is.
10:35They are strength, cheerfulness, health, lightness.
10:43How pretty.
10:45It's like the colors of a butterfly.
10:51This is not normal; these particles pass through us and we feel nothing.
10:54And where are they going like that?
10:55Ah, they pass. They reflect images of the outside world.
10:59These shapes, these colors.
11:01And finally, teacher, where do these shapes and colors go?
11:03Ah, there we are. Where are they going?
11:05But further on, to a place called the back of the eye,
11:09where we will receive their message and pass it on.
11:15You see, the photons that the waves carry
11:17will strike the tissue lining the back of the eye,
11:19what is called the retina.
11:21And there you find millions and millions of them
11:23receptor nerve cells,
11:25cones and sticks.
11:27Is that clear?
11:29Yeah !
11:30Okay, so I'll start again.
11:31Yes !
11:32A ray of light strikes the retina.
11:37The information is reflected, then transmitted.
11:45Neurotransmitters will take over.
11:50Then the information will travel from cell to cell.
12:24And this continues until the brain is informed
12:27by the part of the brain opposite the eye that perceives.
12:32And that's why we say the left brain sees to the right.
12:35and the right brain on the left.
12:37That's curious, isn't it?
12:47Mom, how do my eyes see the butterfly?
12:51It's not your eyes, darling, it's your brain that sees.
12:54So, my brain has eyes?
12:56Somehow.
12:58But explain it to me, Mom.
13:00How, finally, does he manage to see the brain?
13:02Tell me, I would like to understand.
13:04I'd like to know how the brain does it.
13:17It's beautiful.
13:21I want to know how the brain does it, to see.
13:28What's he doing here?
13:30We're not going to bother the teacher for that, are we?
13:33No, no, you can see he's very busy.
13:38Why doesn't anyone want to tell me anything, huh?
13:44What is this ?
13:46I want to know how the brain does it, to see.
13:49How does he do it?
13:50Now that's a mystery.
13:53It's wonderful.
13:55It's very complicated.
13:57This child is right to want to know.
13:59Little old lady, if I try to explain it to you.
14:02It's good to want to know, that's good.
14:10To know is to understand.
14:12And seeing is already knowing.
14:15Take a look at this machine, what do you think?
14:18What is this ?
14:22Is that an arrow?
14:24Finally, it's an arrow that lengthens and shortens.
14:27Have you ever seen any like that?
14:29I have to say no.
14:32Ah, now it's a weather vane.
14:34And we can even see that it's rotating.
14:36Well done !
14:37So, you see, boy, it was your brain that recognized it, the weather vane.
14:41But those are not your eyes.
14:44And now ?
14:47Well, then?
14:50Well, it's a sun, of course.
14:52Of course.
14:55Oh no, that's not right.
14:56Now it's an orange.
14:57Yet, that task hasn't changed.
14:59Look closely.
15:01That's cheating.
15:02It's a flower now.
15:05And now, can you tell me what it is?
15:08You see, it depends, right?
15:12Ah, and depending on what your brain remembers,
15:15depending on what's happening there,
15:16What you see is not necessarily what he perceives.
15:20Well, you deserved it, didn't you?
15:31Look again at how important interpretation is.
15:34Vase or face? You have to choose.
15:39The eyes receive and transmit messages.
15:42The brain, however, must decide.
15:44Furthermore, two eyes do not always see the same thing.
15:46and not in the same way.
15:47Look closely at your thumb, straight in front of you.
15:50Right now.
15:51Close one eye now.
15:52The other one, and starts again.
15:55It looks like it's moving.
15:59Ah, that's right, it's moving.
16:01It's moving, master, it's moving.
16:02The difference is clearly visible.
16:04Their return comes in the distance.
16:13It's true.
16:15It works, it works.
16:22And yet, there is no doubt, believe me.
16:26That works.
16:27It's time for me to go home.
16:29Mom will worry, my breakfast needs to be served.
16:32I have learned a lot from you, teacher.
16:34Thank you for everything.
16:36What were you doing, Pierrot?
16:38I looked for you everywhere.
16:39Nothing, Mom.
16:40I ate an orange.
16:43But where?
16:54Pierrot, I have a surprise for you, my boy.
16:58What is it, Mom?
17:00Tell me quickly, what is it?
17:01Guess.
17:04A balloon?
17:04Candy?
17:06Or a toy?
17:07No, no, no, no, you didn't find it.
17:09Now, close your eyes very tightly.
17:11Don't look!
17:15There you go, you can take a look.
17:18A small dog.
17:20Is he cute?
17:21Is it mine?
17:24Thank you, Mom.
17:25THANKS.
17:31But be careful, Pierrot, a little dog is not a toy.
17:34It's a responsibility.
17:36He needs to teach her to be clean, to obey you.
17:40So now you have to go to school.
17:41Tie it on securely.
17:42Later, we'll make him a niche.
17:44Yes, Mom.
17:45It's perfectly round.
17:46I think I'll call him Bouboule.
17:55Be good, I have to go to school.
17:57Afterwards, I'll build you a house.
18:00Bouboule, that will suit you very well.
18:18Mommy, mommy, my little dog, he's gone.
18:22He left.
18:23He may have been run over.
18:24He may never be found again.
18:25Never again.
18:26No, come on.
18:27Such a small dog can't go very far.
18:35Yes, tears are an expression of sadness.
18:43Eh ?
18:52Bouboule, mommy, mommy, look, he's back, he's back.
18:55You see, you were wrong to be alarmed.
18:58I knew it, my Pierrot, he couldn't be far away.
19:01But tears can also express happiness.
19:17And besides, tears are essential for the proper functioning of the eyes.
19:49Excellent, excellent.
19:50But something is missing from these reserves of tears.
19:53Add mineral salts.
19:58Wait a minute, there.
19:59It's just ordinary salt.
20:00I need six portions.
20:15That's good, you can shed a few tears to ensure the eye is lubricated.
20:28Subtitling by Radio-Canada
21:04Eye irritation
21:06Increase tear production
21:07Don't forget to add antimicrobial enzymes.
21:14Phew! That's good! Yes, that's good!
21:16Nothing like it to cool down after the race!
21:19Hey there! Swimming is strictly forbidden!
21:22You're going to pollute the tears! Get out of here, and faster than that!
21:28Come on, come on! Hurry up!
21:30Otherwise, you'll get a ticket!
21:33A fine!
21:34I can't, I don't know how to swim!
21:36I can't do it!
21:38That's impossible! What recklessness!
21:40Bring a lifebuoy!
21:42Attention !
21:51But let this be a lesson to you! The weapons depot is not a public bathhouse!
21:55You should know! Absolute sterility!
21:57So, get back to your work!
22:01Nevertheless, there's nothing like a good bath!
22:04I've been told my eye is irritated! We're being asked to take action!
22:07Increase the flow rate! Quickly call in the cleaning enzymes, the lysosomes!
22:12Ah, you see! The window washers!
22:15We are not window cleaners!
22:17We are experienced technicians who operate on the surface of the eye!
22:21We are called lysosomes!
22:22Okay, okay, I was just kidding! Come on, hello! We're going to need you!
22:51The corner of the eye! You have to go to the corner of the eye!
22:54Apparently there is a risk of viral conjunctivitis!
22:57Let's go quickly, get the broom out!
23:03Come and see! There's something suspicious over there, on the conjunctiva!
23:16So, we've been spotted! These enzymes are dangerous, except that he can, and it's every man for himself!
23:22Go first! I'm watching the rearguard!
23:31Viruses, I knew it! Onward, friends, no mercy!
23:34No! No! No! Let's go now! We should be able to get through!
23:43Ha ha! The fat one!
23:45You won't escape me! No!
24:09Your eyes are all red! How many times have I told you not to
24:12rubbing your eyes with dirty hands!
24:14And that's how you risk catching conjunctivitis!
24:20This is life! Life! Life! Life! Life! Life! The
24:27Life! Life! That's life!
24:41The life !
