Good afternoon.
1
25117
2295
Dobar dan.
00:43
As you're all aware, we face difficult economic times.
2
27412
4461
Kao što svi znate, suočeni smo s teškim ekonomskim vremenima.
00:47
I come to you with a modest proposal
3
31873
2452
Dolazim k vama sa skromnim prijedlogom
00:50
for easing the financial burden.
4
34325
2532
za olakšavanje financijskog tereta.
00:52
This idea came to me while talking to
5
36857
1533
Do ove ideje došao sam dok sam razgovarao s
00:54
a physicist friend of mine at MIT.
6
38390
2972
prijateljem fizičarem na MIT-u (Massachusetts Institute of Technology)
00:57
He was struggling to explain something to me:
7
41362
2689
Trudio se objasniti mi nešto:
00:59
a beautiful experiment that uses lasers to cool down matter.
8
44051
4576
prekrasan eksperiment koji koristi lasere kako bi ohladio materiju.
01:04
Now he confused me from the very start,
9
48627
1907
Na samom početku me zbunio,
01:06
because light doesn't cool things down.
10
50534
2354
jer svjetlost ne hladi stvari.
01:08
It makes it hotter. It's happening right now.
11
52888
3449
Ona ih čini toplijima. To se događa upravo sada.
01:12
The reason that you can see me standing here is because
12
56337
2543
Razlog zbog kojeg me možete vidjeti kako ovdje stojim jest taj
01:14
this room is filled with more than 100 quintillion photons,
13
58880
3772
što je ova prostorija ispunjena s više od 100 kvadrilijuna (10ˆ24) fotona
01:18
and they're moving randomly through the space, near the speed of light.
14
62652
3535
koji se kreću nasumično kroz prostor brzinom približnom brzini svjetlosti.
01:22
All of them are different colors,
15
66187
1516
Svi oni su različitih boja,
01:23
they're rippling with different frequencies,
16
67703
1940
šire se u različitim frekvencijama
01:25
and they're bouncing off every surface, including me,
17
69643
2875
i odskakuju od svake površine, uključujući i mene,
01:28
and some of those are flying directly into your eyes,
18
72518
2410
a neki od njih lete izravno u vaše oči
01:30
and that's why your brain is forming an image of me standing here.
19
74928
3200
i zbog toga vaš mozak oblikuje sliku mene kako stojim ovdje.
01:34
Now a laser is different.
20
78128
1655
Međutim, laser je drugačiji.
01:35
It also uses photons, but they're all synchronized,
21
79783
4003
On također koristi fotone, ali oni su svi usklađeni
01:39
and if you focus them into a beam,
22
83786
2707
i ako ih usmjerite u zraku
01:42
what you have is an incredibly useful tool.
23
86493
2395
ono što dobijete je nevjerojatno korisno oruđe.
01:44
The control of a laser is so precise
24
88888
2136
Kontrola lasera je tako precizna
01:46
that you can perform surgery inside of an eye,
25
91024
2674
da možete izvesti operaciju oka,
01:49
you can use it to store massive amounts of data,
26
93698
2645
možete ga koristiti za pohranu ogromne količine podataka
01:52
and you can use it for this beautiful experiment
27
96343
2330
te ga možete koristiti za ovaj prekrasan eksperiment
01:54
that my friend was struggling to explain.
28
98673
2473
kojeg se moj prijatelj trudio objasniti.
01:57
First you trap atoms in a special bottle.
29
101146
3255
Prvo zarobite atome u posebnu bocu.
02:00
It uses electromagnetic fields to isolate the atoms
30
104401
2960
Ona koristi elektromagnetsko polje kako bi izolirala atome
02:03
from the noise of the environment.
31
107361
2186
od buke iz okoline.
02:05
And the atoms themselves are quite violent,
32
109547
2483
Atomi sami po sebi također su veoma nasilni,
02:07
but if you fire lasers that are precisely tuned to the right frequency,
33
112030
4044
ali ako pucate laserima koji su točno namješteni na pravu frekvenciju,
02:11
an atom will briefly absorb those photons
34
116074
2628
atom će nakratko upiti te fotone
02:14
and tend to slow down.
35
118702
1883
i usporiti.
02:16
Little by little it gets colder
36
120585
3312
Malo pomalo postaje hladniji
02:19
until eventually it approaches absolute zero.
37
123897
4513
dok se u konačnici ne približi apsolutnoj nuli.
02:24
Now if you use the right kind of atoms and you get them cold enough,
38
128410
3176
Ako koristite pravu vrstu atoma i dovoljno ih ohladite,
02:27
something truly bizarre happens.
39
131586
3777
dogodit će se nešto uistinu neobično.
02:31
It's no longer a solid, a liquid or a gas.
40
135363
2822
To više nije čvrsta tvar, tekućina ili plin.
02:34
It enters a new state of matter called a superfluid.
41
138185
3940
Ono ulazi u novo stanje tvari zvano supertekućina.
02:38
The atoms lose their individual identity,
42
142125
2287
Atomi gube svoj vlastiti identitet,
02:40
and the rules from the quantum world take over,
43
144412
2827
a pravila kvantnog svijeta stupaju na snagu
02:43
and that's what gives superfluids such spooky properties.
44
147239
4095
i to je ono što supertekućini daje tako zastrašujuća svojstva.
02:47
For example, if you shine light through a superfluid,
45
151334
3452
Primjerice, ukoliko usmjerite svjetlost kroz supertekućinu
02:50
it is able to slow photons down
46
154786
3025
ona je u stanju usporiti fotone
02:53
to 60 kilometers per hour.
47
157811
3159
na 60 km/h.
03:03
Another spooky property is that it flows
48
167585
3053
Drugo zastrašujuće svojstvo jest da teče
03:06
with absolutely no viscosity or friction,
49
170638
2636
bez imalo viskoznosti i trenja
03:09
so if you were to take the lid off that bottle,
50
173274
2264
tako da ako otvorite poklopac te boce
03:11
it won't stay inside.
51
175538
2095
ona neće ostati unutra.
03:13
A thin film will creep up the inside wall,
52
177633
2777
Tanki film gmizat će uz unutrašnji zid
03:16
flow over the top and right out the outside.
53
180410
4224
preliti se preko ruba te izići van.
03:20
Now of course, the moment that it does hit the outside environment,
54
184634
2957
Naravno, u trenutku u kojem dođe u dodir s vanjskom okolinom,
03:23
and its temperature rises by even a fraction of a degree,
55
187591
3716
te se njena temperatura povisi samo za djelić stupnja
03:27
it immediately turns back into normal matter.
56
191307
2123
ona se odmah vraća u normalno stanje tvari.
03:29
Superfluids are one of the most fragile things we've ever discovered.
57
193430
3566
Supertekućina je jedna od najkrhkijih stvari ikad otkrivenih.
03:32
And this is the great pleasure of science:
58
196996
2361
I to je veliko zadovoljstvo znanosti:
03:35
the defeat of our intuition through experimentation.
59
199357
4215
poraz naše intuicije eksperimentiranjem.
03:39
But the experiment is not the end of the story,
60
203572
1689
Ali eksperiment nije kraj priče,
03:41
because you still have to transmit that knowledge to other people.
61
205261
3526
jer još uvijek trebate prenijeti to znanje na druge ljude.
03:44
I have a Ph.D in molecular biology.
62
208787
2376
Ja imam doktorat iz molekularne biologije.
03:47
I still barely understand what most scientists are talking about.
63
211163
3533
Još uvijek jedva razumijem o čemu većina znanstvenika priča.
03:50
So as my friend was trying to explain that experiment,
64
214696
2950
I kako je moj prijatelj pokušavao objasniti taj eksperiment,
03:53
it seemed like the more he said,
65
217646
2946
činilo se da što mi je više objašnjavao
03:56
the less I understood.
66
220592
2973
to sam ga manje razumio.
03:59
Because if you're trying to give someone the big picture
67
223565
2371
Jer, ukoliko želite nekome dati cjelokupnu sliku
04:01
of a complex idea, to really capture its essence,
68
225936
4079
složene ideje, da bi uistinu došli do biti,
04:05
the fewer words you use, the better.
69
230015
3583
što manje riječi koristite to bolje.
04:09
In fact, the ideal may be to use no words at all.
70
233598
3319
Zapravo, možda bi bilo idealno ne koristiti riječi uopće.
04:12
I remember thinking, my friend could have explained
71
236917
1557
Sjećam se da sam razmišljao kako je moj prijatelj mogao objasniti
04:14
that entire experiment with a dance.
72
238474
3132
taj cijeli eksperiment plesom.
04:17
Of course, there never seem to be any dancers around when you need them.
73
241606
4368
Naravno, uvijek se čini da nema plesača uokolo, kada ih trebate.
04:21
Now, the idea is not as crazy as it sounds.
74
245974
1889
Ideja nije luda kao što se čini.
04:23
I started a contest four years ago called Dance Your Ph.D.
75
247863
3502
Prije četiri godine započeo sam natjecanje pod imenom „Otpleši svoj doktorat“.
04:27
Instead of explaining their research with words,
76
251365
2615
Umjesto da objašnjavaju svoje istraživanje riječima.
04:29
scientists have to explain it with dance.
77
253980
2900
znanstvenici ga moraju objasniti plesom.
04:32
Now surprisingly, it seems to work.
78
256880
2369
Iznenađujuće, čini se da funkcionira.
04:35
Dance really can make science easier to understand.
79
259249
3272
Ples uistinu može učiniti znanost jednostavnijom.
04:38
But don't take my word for it.
80
262521
1796
Ali nemojte me uzeti za riječ.
04:40
Go on the Internet and search for "Dance Your Ph.D."
81
264317
2887
Idite na Internet i potražite „Dance Your Ph.D.“
04:43
There are hundreds of dancing scientists waiting for you.
82
267204
3258
Ondje su stotine rasplesanih znanstvenika koji vas čekaju.
04:46
The most surprising thing that I've learned while running this contest
83
270462
2083
Iznenađujuća stvar koju sam naučio vodeći to natjecanje
04:48
is that some scientists are now working directly with dancers on their research.
84
272545
5289
jest da neki znanstvenici sada rade izravno s plesačima na svojim istraživanjima.
04:53
For example, at the University of Minnesota,
85
277834
1880
Primjerice, na Sveučilištu Minnesota
04:55
there's a biomedical engineer named David Odde,
86
279714
2505
postoji biomedicinski inženjer David Odde
04:58
and he works with dancers to study how cells move.
87
282219
3158
koji radi s plesačima pri proučavanju kako se stanice kreću.
05:01
They do it by changing their shape.
88
285377
2409
One to čine mjenjajući svoj oblik.
05:03
When a chemical signal washes up on one side,
89
287786
2819
Kada kemijski signal dopre s jedne strane,
05:06
it triggers the cell to expand its shape on that side,
90
290605
3125
on aktivira stanice da prošire svoj oblik s te strane
05:09
because the cell is constantly touching and tugging at the environment.
91
293730
3281
jer stanica neprestao dodiruje okolinu.
05:12
So that allows cells to ooze along in the right directions.
92
297011
3971
To omogućava stanicama da se kreću u pravim smjerovima.
05:16
But what seems so slow and graceful from the outside
93
300982
3938
Ali, ono što se čini polaganim i dostojanstvenim izvana
05:20
is really more like chaos inside,
94
304920
2429
iznutra nalikuje više na kaos
05:23
because cells control their shape with a skeleton of rigid protein fibers,
95
307349
4403
jer stanice kontroliraju svoj oblik kosturom od nesavitljivih proteinskih vlakana,
05:27
and those fibers are constantly falling apart.
96
311752
2845
a ta vlakna se neprestano raspadaju.
05:30
But just as quickly as they explode,
97
314597
2569
Ali onom brzinom kojom eksplodiraju,
05:33
more proteins attach to the ends and grow them longer,
98
317166
2417
više proteina prihvaća se za krajeve te ih izdužuje
05:35
so it's constantly changing
99
319583
2183
tako da se neprestano mijenjaju
05:37
just to remain exactly the same.
100
321766
2998
kako bi ostale potpuno iste.
05:40
Now, David builds mathematical models of this and then he tests those in the lab,
101
324764
3170
David pravi matematičke modele od toga, a zatim ih testira u laboratoriju,
05:43
but before he does that, he works with dancers
102
327934
2775
ali prije nego to učini, radi s plesačima
05:46
to figure out what kinds of models to build in the first place.
103
330709
3701
kako bi shvatio koje modele uopće treba praviti.
05:50
It's basically efficient brainstorming,
104
334410
3093
To je u biti učinkovita oluja ideja
05:53
and when I visited David to learn about his research,
105
337503
2255
i kada sam posjetio Davida kako bih naučio o njegovom istraživanju,
05:55
he used dancers to explain it to me
106
339758
3344
on je koristio plesače da mi to objasni
05:59
rather than the usual method: PowerPoint.
107
343102
4542
umjesto uobičajene metode: PowerPointa.
06:03
And this brings me to my modest proposal.
108
347644
2353
I to me dovodi do mog skromnog prijedloga.
06:05
I think that bad PowerPoint presentations
109
349997
2869
Smatram da su loše PowerPoint prezentacije
06:08
are a serious threat to the global economy.
110
352866
2672
ozbiljna prijetnja globalnoj ekonomiji.
06:11
(Laughter) (Applause)
111
355538
7929
(Smijeh) (Pljesak)
06:19
Now it does depend on how you measure it, of course,
112
363467
4879
Naravno, ovisi o tome kako to mjerite,
06:24
but one estimate has put the drain at 250 million dollars per day.
113
368346
4769
ali po nekim procjenama šteta iznosi 250 milijuna dolara dnevno.
06:29
Now that assumes half-hour presentations
114
373115
2181
To podrazumijeva polusatne prezentacije
06:31
for an average audience of four people
115
375296
2057
za prosječan publiku od četiri osobe
06:33
with salaries of 35,000 dollars,
116
377353
2319
s plaćom od 35 000 dolara
06:35
and it conservatively assumes that
117
379672
1960
te otprilike dovodi do procjene
06:37
about a quarter of the presentations are a complete waste of time,
118
381632
3932
da je oko četvrtine prezentacija potpuni gubitak vremena
06:41
and given that there are some apparently
119
385564
2579
te uzmimo da je
06:44
30 million PowerPoint presentations created every day,
120
388143
3272
30 milijuna PowerPoint prezentacija napravljeno svaki dan,
06:47
that would indeed add up to an annual waste
121
391415
2888
to bi svakako dovelo do godišnjeg gubitka
06:50
of 100 billion dollars.
122
394303
3096
od 100 milijardi dolara.
06:53
Of course, that's just the time we're losing
123
397399
2368
Naravno, to je samo vrijeme koje smo izgubili
06:55
sitting through presentations.
124
399767
2223
sjedeći na tim prezentacijama.
06:57
There are other costs, because PowerPoint is a tool,
125
401990
4316
Postoje i drugi troškovi, jer PowerPoint je alat
07:02
and like any tool, it can and will be abused.
126
406306
3330
i kao svaki drugi alat, može i bit će zloupotrebljen.
07:05
To borrow a concept from my country's CIA,
127
409636
2490
Posudit ću CIA-inu ideju;
07:08
it helps you to soften up your audience.
128
412126
3115
Ono vam pomaže omekšati publiku.
07:11
It distracts them with pretty pictures, irrelevant data.
129
415241
4248
Ometa ih lijepim slikama i nevažnim podacima.
07:15
It allows you to create the illusion of competence,
130
419489
3740
Omogućava vam da stvorite iluziju sposobnosti,
07:19
the illusion of simplicity,
131
423229
2760
iluziju jednostavnosti
07:21
and most destructively, the illusion of understanding.
132
425989
4727
i, što je najpogubnije, iluziju razumijevanja.
07:26
So now my country is 15 trillion dollars in debt.
133
430716
4244
Moja država je dužna 15 bilijuna dolara.
07:30
Our leaders are working tirelessly to try and find ways to save money.
134
434960
4985
Naše vođe rade neumorno na pronalasku načina uštede novca.
07:35
One idea is to drastically reduce public support for the arts.
135
439945
4469
Jedna od ideja jest da se drastično smanji javna potpora umjetnosti.
07:40
For example, our National Endowment for the Arts,
136
444414
2208
Primjerice, naša Nacionalna zaklada za umjetnost
07:42
with its $150 million budget,
137
446622
2577
sa svojim proračunom od 150 milijuna dolara,
07:45
slashing that program would immediately reduce the national debt
138
449199
3012
ukidanje tog programa bi odmah smanjilo nacionalni dug
07:48
by about one one-thousandth of a percent.
139

za jednu tisućinku postotka.
07:51
One certainly can't argue with those numbers.
140
455572
1740
Jednostavno ne možemo proturječiti tim brojkama.
07:53
However, once we eliminate public funding for the arts,
141
457312
5282
Međutim, jednom kada ukinemo javno financiranje umjetnosti
07:58
there will be some drawbacks.
142
462594
2672
dogodit će se nekoliko posljedica.
08:01
The artists on the street will swell the ranks of the unemployed.
143
465266
4396
Umjetnici na ulicama povećat će brojke nezaposlenih.
08:05
Many will turn to drug abuse and prostitution,
144
469662
2407
Mnogi će se okrenuti zlouporabi droge i prostituciji,
08:07
and that will inevitably lower property values in urban neighborhoods.
145
472069
3119
i to će neizbježno smanjiti vrijednost zemljišta u gradskim četvrtima.
08:11
All of this could wipe out the savings we're hoping to make in the first place.
146
475188
4907
Sve ovo moglo bi izbrisati uštede koje smo prvobitno željeli napraviti.
08:15
I shall now, therefore, humbly propose my own thoughts,
147
480095
3241
Stoga ću sada skromno predložiti vlastite misli
08:19
which I hope will not be liable to the least objection.
148
483336
3782
za koje se nadam da neće biti ni najmanje prigovora.
08:23
Once we eliminate public funding for the artists,
149
487118
1893
Jednom kada uklonimo javno financiranje umjetnika,
08:24
let's put them back to work
150
489011
1587
zaposlimo ih ponovno
08:26
by using them instead of PowerPoint.
151
490598
3021
koristeći ih umjesto PowerPointa.
08:29
As a test case, I propose we start with American dancers.
152
493619
3483
Za probu, predlažem da krenemo s američkim plesačima.
08:33
After all, they are the most perishable of their kind,
153
497102
2153
Naposljetku, oni su najpotrošniji,
08:35
prone to injury and very slow to heal
154
499255
2159
podložni ozljedama i veoma sporom zacjeljivanju
08:37
due to our health care system.
155
501414
2817
zbog našeg zdravstvenog sistema.
08:40
Rather than dancing our Ph.Ds,
156
504231
3143
Umjesto da otplešemo svoje doktorate
08:43
we should use dance to explain all of our complex problems.
157
507374
3614
trebali bismo koristiti ples da objasnimo sve svoje složene probleme.
08:46
Imagine our politicians using dance
158
510988
2860
Zamislite naše političare kako koriste ples
08:49
to explain why we must invade a foreign country
159
513848
3778
kako bi objsnili zašto moramo napasti stranu zemlju
08:53
or bail out an investment bank.
160
517626
2872
ili pomoći investicijskoj banci.
08:56
It's sure to help.
161
520498
1962
To bi sigurno pomoglo.
08:58
Of course someday, in the deep future,
162
522460
3752
Naravno, jednog dana u dalekoj budućnosti
09:02
a technology of persuasion
163
526212
2381
tehnologija uvjeravanja
09:04
even more powerful than PowerPoint may be invented,
164
528593
3429
snažnija od PowerPointa bi mogla biti izumljena
09:07
rendering dancers unnecessary as tools of rhetoric.
165
532022
3544
ostavljajući plesače nepotrebnim alatima retorike.
09:11
However, I trust that by that day,
166
535566
2576
Međutim, vjerujem da ćemo do toga dana
09:14
we shall have passed this present financial calamity.
167
538142
3315
proći sadašnju ekonomsku propast.
09:17
Perhaps by then we will be able to afford the luxury
168
541457
3366
Možda ćemo tada biti u mogućnosti priuštiti si luksuz
09:20
of just sitting in an audience
169
544823
3120
da samo sjedimo u publici
09:23
with no other purpose
170
547943
1840
bez neke druge svrhe
09:25
than to witness the human form in motion.
171
549783
4566
osim da svjedočimo ljudskom obliku u pokretu.

Black Label Movement - Dance troupe
Black Label Movement is an explosively physical Minneapolis dance company.
Why you should listen
Black Label Movement is a Twin Cities-based dance theater dedicated to creating wildly physical, naturally virtuosic, intellectually and emotionally engaging art. Led by Carl Flink, this collective of dance artists seeks to push the mind, body, and heart to the edge of what is possible and beyond.
A one-time company member and soloist with the New York City-based Limón Dance Company, Flink is known for choreography with intense athleticism, daring risk taking and humanistic themes that address diverse social, scientific, political and working class subjects in addition to more abstract dance approaches. He is also the endowed Nadine Jette Sween Professor of Dance and Chair of the Department of Theatre Arts and Dance at the University of Minnesota-Twin Cities. Beyond the dance world, he graduated from Stanford Law School in 2001 and worked as a staff attorney with Farmers' Legal Action Group, Inc. protecting the legal rights of low-income family farmers and promoting sustainable agriculture until 2004.
