1
If you've ever been fortunate enough to witness the spectacle of a huge flock of birds twisting and swooping through the sky,
2
I'm sure the same thought occurred to you,
3
which is, this looks lovely,
4
but how are they not absolutely smashing into each other?
5
These patterns are called murmurations, by the way.
6
You can get tens of thousands of starlings,
7
sometimes hundreds of thousands, all swirling around in this synchronised aerial ballet for up to 45 minutes before sunset,
8
and then, boom, all dropping out of the sky at once, safely, to roost.
9
for the night.
10
And for years, people had no idea how they could possibly do this.
11
And then in 1931, a perfectly respectable British biologist published a book,
12
and I cannot stress enough that this is a real book,
13
called Thought Transference in Birds.
14
His conclusion, having thought about it very,
15
very hard, was that the birds must be telepathic.
16
I love him, but also no. The actual answer turned up in 1986 from,
17
of all people, a computer programmer called Craig Reynolds,
18
who was just trying to make a halfway convincing a flock of birds for an animation.
19
And he discovered something genuinely remarkable.
20
You don't need to model the whole flock.
21
The birds aren't thinking about the flock.
22
They aren't thinking about the bigger picture at all.
23
It's a bird equivalent of a Mexican wave.
24
Each bird is following three rules.
25

27
And three, roughly stay near them.

That's the whole murmuration.

There isn't any leader.
31

32
There's no bird squawking instructions to the others.
33
There's no telepathy.
34
Just every bird
35
paying attention only to the handful of birds in its immediate bubble
36
and adjusting its behavior accordingly and out of out of
37
that I mean you you get this right his algorithm these
38
three rules a few lines of codes produces flocking behavior
39
that is so accurate
40
that it is used in films in self-driving car research in
41
crowd safety in robotics in modeling how rumors spread in how
42
diseases spread in how protest form in how fish school
43
and how cities move all from this same insight
44
that you don't get a beautiful cohesive whole by having a
45
beautiful cohesive plan actually you get it by having every individual
46
quietly paying attention to the people who are right next to them
47
and adjusting their behavior accordingly which if you think about it is
48
is also basically the deal with being a good person

Qu'est-ce que la technique du Shadowing ?

Le Shadowing est une technique d'apprentissage des langues fondée sur la science, développée à l'origine pour la formation des interprètes professionnels. Le principe est simple mais puissant : vous écoutez de l'anglais natif et le répétez immédiatement à voix haute — comme une ombre suivant le locuteur avec un décalage de 1 à 2 secondes. Les recherches montrent une amélioration significative de la précision de la prononciation, de l'intonation, du rythme, des liaisons, de la compréhension orale et de la fluidité.
