ABOUT THE SPEAKER
Arthur Benjamin - Mathemagician
Using daring displays of algorithmic trickery, lightning calculator and number wizard Arthur Benjamin mesmerizes audiences with mathematical mystery and beauty.

Why you should listen

Arthur Benjamin makes numbers dance. In his day job, he's a professor of math at Harvey Mudd College; in his other day job, he's a "Mathemagician," taking the stage in his tuxedo to perform high-speed mental calculations, memorizations and other astounding math stunts. It's part of his drive to teach math and mental agility in interesting ways, following in the footsteps of such heroes as Martin Gardner.

Benjamin is the co-author, with Michael Shermer, of Secrets of Mental Math (which shares his secrets for rapid mental calculation), as well as the co-author of the MAA award-winning Proofs That Really Count: The Art of Combinatorial Proof. For a glimpse of his broad approach to math, see the list of research talks on his website, which seesaws between high-level math (such as his "Vandermonde's Determinant and Fibonacci SAWs," presented at MIT in 2004) and engaging math talks for the rest of us ("An Amazing Mathematical Card Trick").

Il y a toujours quelqu'un pour demander au professeur de maths, "Est-ce que je vais utiliser le calcul dans la vraie vie ? Et pour la plupart d'entre nous, dit Arthur Benjamin,la réponse est non. Il fait une proposition audacieuse sur la manière de rendre l'enseignement des mathématiques pertinent à l'ère du numérique.

Now, if President Obama

3000
SI le président Obama
00:15
invited me to be the next Czar of Mathematics,
1
3000
4000
m'invitait à être le prochain tsar des Mathématiques,
00:19
then I would have a suggestion for him
2
7000
3000
j'aurais une suggestion à lui faire
00:22
that I think would vastly improve
3
10000
2000
qui je pense améliorerait grandement
00:24
the mathematics education in this country.
4
12000
3000
l'enseignement des mathématiques dans ce pays.
00:27
And it would be easy to implement
5
15000
2000
Et ce serait facile à implémenter
00:29
and inexpensive.
6
17000
2000
et ça ne coûterait pas cher.
00:31
The mathematics curriculum that we have
7
19000
2000
Le programme de mathématiques que nous avons
00:33
is based on a foundation of arithmetic and algebra.
8
21000
4000
est fondé sur l'arithmétique et l'algèbre.
00:37
And everything we learn after that
9
25000
2000
Et tout ce que nous apprenons par la suite
00:39
is building up towards one subject.
10
27000
3000
tend vers un unique sujet.
00:42
And at top of that pyramid, it's calculus.
11
30000
4000
Et au sommet de la pyramide, il y a le calcul.
00:46
And I'm here to say
12
34000
2000
Et je suis ici pour dire
00:48
that I think that that is the wrong summit of the pyramid ...
13
36000
4000
que je pense que ce n'est pas le bon sommet de la pyramide ...
00:52
that the correct summit -- that all of our students,
14
40000
2000
que le bon sommet .. que tous nos étudiants,
00:54
every high school graduate should know --
15
42000
2000
tout bachelier devrait connaître,
00:56
should be statistics:
16
44000
3000
devrait être les statistiques :
00:59
probability and statistics.
17
47000
2000
la probabilité et les statistiques.
01:01
(Applause)
18
49000
2000
(Applaudissements)
01:03
I mean, don't get me wrong. Calculus is an important subject.
19
51000
4000
Je veux dire, comprenez moi bien. Le calcul est un sujet important.
01:07
It's one of the great products of the human mind.
20
55000
2000
C'est l'un des plus grands produits de l'esprit humain.
01:09
The laws of nature are written in the language of calculus.
21
57000
4000
Les lois de la nature sont écrites dans le langage du calcul.
01:13
And every student who studies math, science, engineering, economics,
22
61000
4000
Et tous les étudiants qui étudient les maths, les sciences, l'ingénierie, l'économie,
01:17
they should definitely learn calculus
23
65000
2000
devraient absolument apprendre le calcul
01:19
by the end of their freshman year of college.
24
67000
2000
avant la fin de leur première année de fac.
01:21
But I'm here to say, as a professor of mathematics,
25
69000
3000
Mais je suis ici pour dire, en tant que professeur de mathématiques,
01:24
that very few people actually use calculus
26
72000
4000
que très peu de gens se servent en fait du calcul
01:28
in a conscious, meaningful way, in their day-to-day lives.
27
76000
3000
d'une manière consciente et significative, dans leurs vies quotidiennes.
01:31
On the other hand,
28
79000
2000
Par ailleurs,
01:33
statistics -- that's a subject that you could,
29
81000
3000
les statistiques, c'est un sujet que vous pourriez,
01:36
and should, use on daily basis. Right?
30
84000
3000
et devriez, utiliser au quotidien. N'est-ce-pas?
01:39
It's risk. It's reward. It's randomness.
31
87000
3000
C'est le risque, c'est la récompense, c'est l'aléatoire.
01:42
It's understanding data.
32
90000
2000
C'est comprendre les données.
01:44
I think if our students, if our high school students --
33
92000
2000
Je pense que si nos étudiants, si nos lycéens,
01:46
if all of the American citizens --
34
94000
2000
si tous les citoyens américains,
01:48
knew about probability and statistics,
35
96000
3000
connaissaient les probabilités et les statistiques,
01:51
we wouldn't be in the economic mess that we're in today. (Laughter) (Applause)
36
99000
3000
nous ne serions pas dans le marasme économique dans lequel nous sommes aujourd'hui. (Rires) (Applaudissements)
01:54
Not only -- thank you -- not only that ...
37
102000
3000
Non seulement, merci, non seulement ça,
01:57
but if it's taught properly, it can be a lot of fun.
38
105000
3000
mais si on l'enseigne comme il faut, ça peut être très amusant.
02:00
I mean, probability and statistics,
39
108000
2000
Je veux dire, les probabilités et les statistiques,
02:02
it's the mathematics of games and gambling.
40
110000
4000
ce sont les mathématiques des jeux et des paris.
02:06
It's analyzing trends. It's predicting the future.
41
114000
4000
C'est l'analyse des tendances, c'est prédire l'avenir.
02:10
Look, the world has changed
42
118000
2000
Voyez, le monde est passé
02:12
from analog to digital.
43
120000
3000
de l'analogique au numérique.
02:15
And it's time for our mathematics curriculum to change
44
123000
3000
Et il est temps pour notre programme de mathématiques de passer
02:18
from analog to digital,
45
126000
2000
de l'analogique au numérique,
02:20
from the more classical, continuous mathematics,
46
128000
4000
des mathématiques les plus classiques et continues
02:24
to the more modern, discrete mathematics --
47
132000
3000
aux mathématiques plus modernes et plus discrètes,
02:27
the mathematics of uncertainty,
48
135000
2000
les mathématiques de l'incertitude,
02:29
of randomness, of data --
49
137000
2000
de l'aléatoire, des données,
02:31
that being probability and statistics.
50
139000
3000
que sont les probabilités et les statistiques.
02:34
In summary, instead of our students
51
142000
2000
En résumé, au lieu que nos étudiants
02:36
learning about the techniques of calculus,
52
144000
3000
apprennent les techniques de calcul,
02:39
I think it would be far more significant
53
147000
3000
je pense que ça aurait beaucoup plus de sens
02:42
if all of them knew what two standard deviations
54
150000
3000
s' ils savaient tous ce que deux écarts-types
02:45
from the mean means. And I mean it.
55
153000
3000
de la médiane signifie. Et je le pense vraiment.
02:48
Thank you very much.
56
156000
2000
Merci beaucoup.
02:50
(Applause)
