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").

1
3000
4000
menawarkan saya untuk menjadi Ketua Matematik yang baru,
00:19
then I would have a suggestioncadangan for him

3000
maka saya ada satu cadangan untuknya
00:22
that I think would vastlyjauh improvememperbaiki
3
10000
2000
yang saya fikir akan dapat banyak memperbaiki
00:24
the mathematicsmatematik educationpendidikan in this countrynegara.

00:27

Dan ia mudah untuk dilaksanakan
00:29

dan tidak mahal.
00:31
The mathematicsmatematik curriculumkurikulum that we have
7
19000
2000
Kurikulum matematik kita
00:33
is basedberasaskan on a foundationasas of arithmeticaritmetik and algebraalgebra.
8
21000
4000
adalah berdasarkan pada asas aritmetik dan algebra.
00:37
And everything we learnbelajar after that
9
25000
2000
Dan segala-gala yang kita pelajari selepas itu
00:39
is buildingbangunan up towardske arah one subjectsubjek.
10
27000
3000
membina ke arah satu subjek.
00:42
And at topatas of that pyramidpiramid, it's calculuskalkulus.
11
30000
4000
Dan di puncak piramid itu ialah kalkulus.
00:46
And I'm here to say
12
34000
2000
Dan saya di sini mahu memperkatakan
00:48
that I think that that is the wrongsalah summitpuncak of the pyramidpiramid ...
13
36000
4000
bahawa itu adalah puncak piramid yang salah...
00:52
that the correctbetul summitpuncak -- that all of our studentspelajar,
14
40000
2000
puncak yang betul -- di mana semua pelajar kita,
00:54
everysetiap hightinggi schoolsekolah graduategraduan should know --
15
42000
2000
setiap lulusan sekolah tinggi perlu tahu --
00:56
should be statisticsstatistik:
16
44000
3000
sepatutnya ialah statistik:
00:59
probabilitykebarangkalian and statisticsstatistik.
17
47000
2000
kebarangkalian dan statistik.
01:01
(ApplauseTepukan)
18
49000
2000
(Tepuk tangan)
01:03
I mean, don't get me wrongsalah. CalculusKalkulus is an importantpenting subjectsubjek.
19
51000
4000
Maksud saya, jangan salah faham. Kalkulus ialah mata pelajaran yang penting.
01:07
It's one of the great productsproduk of the humanmanusia mindfikiran.
20
55000
2000
Ia suatu hasil minda manusia yang hebat.
01:09
The lawsundang-undang of naturesifat are writtenbertulis in the languagebahasa of calculuskalkulus.
21
57000
4000
Undang-undang alam ditulis dalam bahasa kalkulus.
01:13
And everysetiap studentpelajar who studieskajian mathmatematik, sciencesains, engineeringkejuruteraan, economicsekonomi,
22
61000
4000
Dan setiap pelajar yang mempelajari matematik, sains, kejuruteraan, ekonomi,
01:17
they should definitelypasti learnbelajar calculuskalkulus
23
65000
2000
mereka tentu belajar kalkulus
01:19
by the endakhir of theirmereka freshmantahun pertama yeartahun of collegekolej.
24
67000
2000
di akhir tahun pertama di kolej.
01:21
But I'm here to say, as a professorprofesor of mathematicsmatematik,
25
69000
3000
Dan di sini saya mahu memperkatakan, sebagai seorang profesor matematik,
01:24
that very fewbeberapa people actuallysebenarnya use calculuskalkulus
26
72000
4000
bahawa segelintir orang yang benar-benar menggunakan kalkulus
01:28
in a conscioussedar, meaningfulbermakna way, in theirmereka day-to-dayhari ke hari liveshidup.
27
76000
3000
secara sedar, bermakna dan dalam kehidupan seharian mereka.
01:31
On the other handtangan,
28
79000
2000
Sebaliknya,
01:33
statisticsstatistik -- that's a subjectsubjek that you could,
29
81000
3000
statistik – itu satu mata pelajaran yang anda boleh,
01:36
and should, use on dailysetiap hari basisdasar. Right?
30
84000
3000
dan patut menggunakannya secara harian. Betul?
01:39
It's riskrisiko. It's rewardganjaran. It's randomnessrawak.
31
87000
3000
Ia mengenai risiko. Mengenai ganjaran. Mengenai kerawakan.
01:42
It's understandingpemahaman datadata.
32
90000
2000
Mengenai pemahaman data.
01:44
I think if our studentspelajar, if our hightinggi schoolsekolah studentspelajar --
33
92000
2000
Saya fikir jika pelajar kita, jika pelajar sekolah tinggi kita --
01:46
if all of the AmericanAmerika Syarikat citizenswarganegara --
34
94000
2000
jika semua warga Amerika --
01:48
knewtahu about probabilitykebarangkalian and statisticsstatistik,
35
96000
3000
faham mengenai kebarangkalian dan statistik,
01:51
we wouldn'ttidak akan be in the economicekonomi messkeadaan huru-hara that we're in todayhari ini. (LaughterGelak ketawa) (ApplauseTepukan)
36
99000
3000
kita tidak akan berada dalam kecelaruan ekonomi yang kita hadapi sekarang.
01:54
Not only -- thank you -- not only that ...
37
102000
3000
Bukan sahaja – terima kasih – bukan sahaja itu...
01:57
but if it's taughtdiajar properlybetul, it can be a lot of funkeseronokan.
38
105000
3000
[tetapi] jika ia diajarkan dengan betul, ia menyeronokkan.
02:00
I mean, probabilitykebarangkalian and statisticsstatistik,
39
108000

Maksud saya, kebarangkalian dan statistik,
02:02
it's the mathematicsmatematik of gamespermainan and gamblingperjudian.
