Prvo, video.
00:16
First, a video.

00:24
Yes, it is a scrambled egg.
1
24657
2802
Da, ovo je umućeno jaje.
Ali kako ga gledate,
00:29
But as you look at it,
2
29411
1333
00:30
I hope you'll begin to feel just slightly uneasy.
3
30768
4111
nadam se da ćete početi da osećate
sasvim malu nelagodu.
00:36
Because you may notice that what's actually happening
4
36649
3338
Jer možda ćete primetiti šta se zaista dešava,
a to je da se jaje samo razumućuje.
00:40
is that the egg is unscrambling itself.
5
40011
2225
00:42
And you'll now see the yolk and the white have separated.
6
42260
2699
I sada ćete videti žumance i belance kako se razdvajaju.
00:44
And now they're going to be poured back into the egg.
7
44983
3023
I kako se vraćaju natrag u jaje.
Svi znamo, intuitivno,
00:48
And we all know in our heart of hearts
8
48030
2468
00:50
that this is not the way the universe works.
9
50522
3015
da ovo nije način na koji univerzum funkcioniše.
00:54
A scrambled egg is mush -- tasty mush -- but it's mush.
10
54696
3105
Umućeno jaje je smeša, ukusna smeša, ali ipak smeša.
00:57
An egg is a beautiful, sophisticated thing
11
57825
2411
Jaje je prelepa, prefinjena stvar
01:00
that can create even more sophisticated things,
12
60260
2239
koja može da stvara još prefinjenije stvari,
01:02
such as chickens.
13
62523
1317
kao što su kokoške.
01:04
And we know in our heart of hearts
14
64332
1904
I duboko u sebi znamo
01:06
that the universe does not travel from mush to complexity.
15
66260
3764
da univerzum ne putuje
od smeše u komplekosnost.
01:10
In fact, this gut instinct
16
70450
2395
Zapravo, ovaj instinkt
01:12
is reflected in one of the most fundamental laws of physics,
17
72869
2872
odražava jedan od najosnovnijih zakona fizike,
01:15
the second law of thermodynamics, or the law of entropy.
18
75765
2825
drugi zakon termodinamike, ili zakon entropije.
Ono što nam taj zakon govori u osnovi je
01:19
What that says basically
19
79162
1759
01:20
is that the general tendency of the universe
20
80945
3127
da je opšta tendencija univerzuma
da se kreće od uređenosti
01:24
is to move from order and structure
21
84096
3603
i strukture
01:27
to lack of order, lack of structure --
22
87723
2664
do manjka uređenosti, manjka strukture --
do smeše, zapravo.
01:30
in fact, to mush.
23
90411
1464
01:31
And that's why that video feels a bit strange.
24
91899
3223
I zbog toga ovaj video
deluje malo čudno.
01:35
And yet, look around us.
25
95685
2729
Pa ipak,
pogledajte unaokolo.
01:39
What we see around us is staggering complexity.
26
99454
3476
Ono što vidimo oko nas
jeste zapanjujuća kompleksnost.
01:43
Eric Beinhocker estimates that in New York City alone,
27
103549
3289
Erik Bajnhoker procenjuje da samo na tržištu Nju Jorka
01:46
there are some 10 billion SKUs, or distinct commodities, being traded.
28
106862
3554
postoji preko 10 milijardi različite robe kojom se trguje,
01:50
That's hundreds of times as many species as there are on Earth.
29
110932
3968
što je hiljadu puta više od vrsta
koje postoje na Zemlji.
01:55
And they're being traded by a species of almost seven billion individuals,
30
115260
3976
I njima trguje vrsta
od oko sedam milijardi pojedinaca
01:59
who are linked by trade, travel, and the Internet
31
119260
3385
koji su povezani kroz trgovinu, putovanja i Internet
02:02
into a global system of stupendous complexity.
32
122669
3689
u celovit sistem
čudesne kompleksnosti.
02:07
So here's a great puzzle:
33
127826
1476
I eto sjajne zagonetke:
U univerzumu
02:10
in a universe ruled by the second law of thermodynamics,
34
130191
4647
u kome važi drugi zakon termodinamike,
02:14
how is it possible
35
134862
1804
kako je moguće
02:16
to generate the sort of complexity I've described,
36
136690
2546
proizvesti takvu složenost kakvu sam opisao --
02:19
the sort of complexity represented by you and me
37
139260
3788
vrstu složenosti koju predstavljamo vi i ja
i kongresni centar?
02:23
and the convention center?
38
143072
1689
Pa, odgovor je izgleda
02:26
Well, the answer seems to be,
39
146119
1953
02:28
the universe can create complexity,
40
148096
3140
da univerzum može stvoriti kompleksnost,
02:31
but with great difficulty.
41
151260
1555
ali sa velikim poteškoćama.
02:33
In pockets,
42
153870
1097
U suštini,
02:34
there appear what my colleague, Fred Spier,
43
154991
2317
dešava se ono što moj kolega, Fred Spir,
02:37
calls "Goldilocks conditions" --
44
157332
2142
zove "Goldilokovi uslovi" --
02:39
not too hot, not too cold,
45
159498
2051
ni prevruće, ni prehladno;
02:41
just right for the creation of complexity.
46
161573
2663
sasvim dovoljno za stvaranje kompleksnosti.
02:44
And slightly more complex things appear.
47
164260
2267
I nešto kompleksnija stvar se dešava.
02:46
And where you have slightly more complex things,
48
166551
2239
A gde imate kompleksne stvari,
02:48
you can get slightly more complex things.
49
168814
2372
možete dobiti još složenije stvari.
I na ovaj način, kompleksnost se gradi
02:51
And in this way, complexity builds stage by stage.
50
171210
4026
stepenicu po stepenicu.
Svaka faza je magična
02:56
Each stage is magical
51
176135
2278
02:58
because it creates the impression of something utterly new
52
178437
3573
jer stvara utisak da se nešto suštinski novo
pojavljuje niotkuda u univerzumu.
03:02
appearing almost out of nowhere in the universe.
53
182034
2803
03:04
We refer in big history to these moments as threshold moments.
54
184861
3231
Mi se u velikoj istoriji odnosimo na ove momente
kao na "nivoe".
I na svakom nivou
03:09
And at each threshold, the going gets tougher.
55
189131
3105
stvari postaju teže.
03:12
The complex things get more fragile,
56
192260
3242
Kompleksne stvari postaju krhkije,
03:15
more vulnerable;
57
195526
1710
ranjivije,
03:17
the Goldilocks conditions get more stringent,
58
197260
3531
Goldilokovi uslovi postaju zahtevniji,
03:20
and it's more difficult to create complexity.
59
200815
2987
i postaje teže
stvoriti kompleksnost.
03:24
Now, we, as extremely complex creatures,
60
204728
3304
E sada, mi kao ekstremno složena bića
očajnički želimo da razumemo priču o tome
03:28
desperately need to know this story
61
208056
2180
03:30
of how the universe creates complexity despite the second law,
62
210260
4658
kako univerzum stvara kompleksnost,
uprkos drugom zakonu,
03:34
and why complexity means vulnerability and fragility.
63
214942
5032
i zašto kompleksnost
znači ranjivost
i krhkost.
03:40
And that's the story that we tell in big history.
64
220745
2920
I to je priča koju pričamo u velikoj istoriji.
03:43
But to do it, you have do something
65
223689
1707
Ali kako bi to uradili, prvo mora da se uradi nešto
03:45
that may, at first sight, seem completely impossible.
66
225420
2705
što na prvi pogled može delovati potpuno nemoguće.
Mora da se premeri čitava istorija univerzuma.
03:48
You have to survey the whole history of the universe.
67
228149
3180
03:52
So let's do it.
68
232748
1000
Pa hajde da to učinimo.
03:54
(Laughter)
69
234260
1909
(Smeh)
03:56
Let's begin by winding the timeline back
70
236193
3446
Počnimo tako što ćemo vratiti sat
03:59
13.7 billion years,
71
239663
2896
13.7 milijardi godina unazad
04:02
to the beginning of time.
72
242583
2677
do početka vremena.
04:12
Around us, there's nothing.
73
252581
1654
Oko nas nema ničega.
04:14
There's not even time or space.
74
254986
2706
Nema ni prostora ni vremena.
04:18
Imagine the darkest, emptiest thing you can
75
258474
3698
Zamislite najmračniju, najprazniju stvar koju možete
i sažmite je milijardu milijardi puta
04:22
and cube it a gazillion times and that's where we are.
76
262196
3317
i eto tu se nalazimo.
04:25
And then suddenly,
77
265992
2340
A onda iznenada,
04:28
bang!
78
268356
1008
tras! Pojavljuje se univerzum, čitav univerzum.
04:29
A universe appears, an entire universe.
79
269388
2207
04:31
And we've crossed our first threshold.
80
271619
1856
I prošli smo kroz prvi nivo.
04:33
The universe is tiny; it's smaller than an atom.
81
273499
2373
Univerzum je mali; manji od atoma.
04:35
It's incredibly hot.
82
275896
1340
I neverovatno je vruć.
04:37
It contains everything that's in today's universe,
83
277260
2525
Sadrži sve što je danas u univerzumu,
04:39
so you can imagine, it's busting.
84
279809
1794
tako da možete zamisliti, da se razbija,
04:41
And it's expanding at incredible speed.
85
281627
2609
i da se širi neverovatnom brzinom.
04:44
And at first, it's just a blur,
86
284260
1913
I najpre je sve vrlo mutno,
04:46
but very quickly distinct things begin to appear in that blur.
87
286197
3110
ali veoma brzo počinju da se izdvajaju stvari u toj maglini.
04:49
Within the first second,
88
289743
1493
U prvoj sekundi,
04:51
energy itself shatters into distinct forces
89
291260
2976
sama energija se razbija u različite sile,
04:54
including electromagnetism and gravity.
90
294260
3082
uključujući elektromagnetizam i gravitaciju.
Energija čini još nešto prilično čudesno
04:57
And energy does something else quite magical:
91
297366
2428
04:59
it congeals to form matter --
92
299818
3232
uobličava se u materiju --
kvarkove koji formiraju protone
05:03
quarks that will create protons
93
303074
2330
i leptone koji uključuju elektrone.
05:05
and leptons that include electrons.
94
305428
2138
05:07
And all of that happens in the first second.
95
307590
2103
I sve se to dešava u prvoj sekundi.
05:09
Now we move forward 380,000 years.
96
309717
4229
Sada idemo 380.000 godina unapred.
05:14
That's twice as long as humans have been on this planet.
97
314260
3647
To je duplo duže nego što ljudi postoje na planeti.
05:17
And now simple atoms appear of hydrogen and helium.
98
317931
4740
I tada se pojavljuje jednostavan atom
vodonika i helijuma.
05:23
Now I want to pause for a moment,
99
323877
1603
Sada bih zastao na momenat,
05:25
380,000 years after the origins of the universe,
100
325504
2732
380,000 godina nakon nastanka univerzuma,
05:28
because we actually know quite a lot about the universe at this stage.
101
328260
3976
jer znamo prilično mnogo
o ovoj fazi razvitka univerzuma.
05:32
We know above all that it was extremely simple.
102
332773
2921
Pre svega znamo da je bio jako jednostavan.
05:35
It consisted of huge clouds of hydrogen and helium atoms,
103
335718
3799
Sastojao se od ogromnih oblaka
sačinjenih od atoma vodonika i helijuma,
05:39
and they have no structure.
104
339541
1928
a oni nisu imali strukturu.
05:41
They're really a sort of cosmic mush.
105
341493
2367
Bili su vrsta kosmičke smeše.
05:44
But that's not completely true.
106
344652
1670
Ali to nije baš potpuno tačno.
05:46
Recent studies
107
346732
1504
Skorije studije
05:48
by satellites such as the WMAP satellite
108
348260
2861
urađene pomoću satelita kao što je WMAP satelit
05:51
have shown that, in fact,
109
351145
1577
pokazale su da, zapravo, postoje samo male razlike u pozadini.
05:52
there are just tiny differences in that background.
110
352746
2749
05:55
What you see here,
111
355519
1717
Ono što vidite ovde,
05:57
the blue areas are about a thousandth of a degree cooler
112
357260
4306
je da su plave zone oko hiljadu stepeni hladnije
od crvenih zona.
06:01
than the red areas.
113
361590
1392
To su male razlike,
06:03
These are tiny differences,
114
363006
1373
06:04
but it was enough for the universe to move on
115
364403
2270
ali dovoljne da univerzum nastavi
06:06
to the next stage of building complexity.
116
366697
1975
do sledeće faze kompleksnosti.
06:08
And this is how it works.
117
368696
1192
I evo kako to funkcioniše.
06:10
Gravity is more powerful where there's more stuff.
118
370895
4248
Gravitacija je moćnija
tamo gde ima više stvari.
06:15
So where you get slightly denser areas,
119
375817
2318
Tako da gde imate gušće zone,
gravitacija počinje da sažima oblake
06:18
gravity starts compacting clouds of hydrogen and helium atoms.
120
378159
3917
vodonikovih i helijumovih atoma.
Možemo zamisliti rani univerzum kako se raspada
06:22
So we can imagine the early universe breaking up into a billion clouds.
121
382100
3550
na milijarde oblaka.
06:25
And each cloud is compacted,
122
385674
1802
I svaki oblak je sabijen,
06:27
gravity gets more powerful as density increases,
123
387500
3016
gravitacija postaje moćnija kako se gustina povećava,
06:30
the temperature begins to rise at the center of each cloud,
124
390540
3094
temperatura počinje da raste u centru svakog oblaka,
a potom u svakom oblaku,
06:33
and then, at the center,
125
393658
1289
06:34
the temperature crosses the threshold temperature
126
394971
2838
temperatura prelazi graničnu temperaturu novog nivoa
06:37
of 10 million degrees,
127
397833
1566
od 10 miliona stepeni,
06:39
protons start to fuse,
128
399423
2405
protoni počinju da se spajaju,
06:41
there's a huge release of energy,
129
401852
2384
ogromna količina energije se oslobađa,
06:44
and --
130
404260
1433
i, tras!
06:45
bam!
131
405717
1016
06:46
We have our first stars.
132
406757
1515
Imamo prvu zvezdu.
06:48
From about 200 million years after the Big Bang,
133
408938
3858
Otprilike 200 miliona godina nakon Velikog praska,
06:52
stars begin to appear all through the universe,
134
412820
3407
zvezde počinju da se pojavljuju širom čitavog univerzuma,
na milijarde njih.
06:56
billions of them.
135
416251
1071
06:57
And the universe is now significantly more interesting
136
417759
2856
I univerzum je sada znatno zanimljiviji
07:00
and more complex.
137
420639
1095
i mnogo kompleksniji.
07:03
Stars will create the Goldilocks conditions
138
423188
3116
Zvezde će formirati Goldilakove uslove
za prolazak kroz još dva nova nivoa
07:06
for crossing two new thresholds.
139
426328
1899
07:08
When very large stars die,
140
428631
2579
Kada veoma velike zvezde umru,
one stvaraju temperature toliko visoke
07:11
they create temperatures so high
141
431234
2321
07:13
that protons begin to fuse in all sorts of exotic combinations,
142
433579
3633
da protoni počinju da se spajaju u sve vrste egzotičnih kombinacija,
i formiraju sve elemente periodnog sistema.
07:17
to form all the elements of the periodic table.
143
437236
2830
Ako, kao ja, nosite zlatan prsten,
07:20
If, like me, you're wearing a gold ring,
144
440090
2296
07:22
it was forged in a supernova explosion.
145
442410
2826
on je nastao u eksploziji supernove.
07:25
So now the universe is chemically more complex.
146
445878
3199
Sada je univerzum hemijski mnogo kompleksniji.
A u hemijski kompleksnijem univerzumu,
07:29
And in a chemically more complex universe,
147
449101
2365
07:31
it's possible to make more things.
148
451490
2444
moguće je mnogo više stvari.
07:33
And what starts happening is that, around young suns,
149
453958
3492
I ono što počinje da se dešava
oko mladih sunaca,
07:37
young stars,
150
457474
1762
mladih zvezda,
07:39
all these elements combine, they swirl around,
151
459260
2191
je to da se ovi elementi kombinuju, kovitlaju se,
07:41
the energy of the star stirs them around,
152
461475
2780
energija oko zvezda ih vrti,
formiraju čestice, formiraju pahuljice,
07:44
they form particles, they form snowflakes, they form little dust motes,
153
464279
4725
male čestice prašine,
koje formiraju stene, asteroide,
07:49
they form rocks, they form asteroids,
154
469028
2196
i konačno formiraju planete i mesece.
07:51
and eventually, they form planets and moons.
155
471248
2595
07:53
And that is how our solar system was formed,
156
473867
2950
Eto kako je nastao naš sunčev sistem,
07:56
four and a half billion years ago.
157
476841
2395
pre četiri i po milijarde godina.
Stenovite planete kao što je naša Zemlja
08:00
Rocky planets like our Earth are significantly more complex than stars
158
480453
5373
značajno su kompleksnije od zvezda
08:05
because they contain a much greater diversity of materials.
159
485850
2762
jer sadrže veću raznolikost materijala.
08:08
So we've crossed a fourth threshold of complexity.
160
488636
2781
I tako smo zakoračili kroz četvrti nivo kompleksnosti.
08:12
Now, the going gets tougher.
161
492931
2627
Sada stvari postaju teže.
08:16
The next stage introduces entities that are significantly more fragile,
162
496411
4278
Sledeća faza nas upoznaje sa stvarima
koje su značajno krhkije,
08:20
significantly more vulnerable,
163
500713
1912
značajno ranjivije,
08:22
but they're also much more creative
164
502649
2587
ali su i mnogo kreativnije
08:25
and much more capable of generating further complexity.
165
505260
2976
i sposobnije da stvaraju kompleksnost u budućnosti.
08:28
I'm talking, of course, about living organisms.
166
508606
3424
Govorim, naravno,
o živim organizmima.
08:32
Living organisms are created by chemistry.
167
512734
2143
Žive organizme je stvorila hemija.
08:34
We are huge packages of chemicals.
168
514901
2383
Mi smo veliki hemijski paketi.
08:38
So, chemistry is dominated by the electromagnetic force.
169
518115
3121
A hemijom upravlja elektromagnetna sila.
08:41
That operates over smaller scales than gravity,
170
521260
2239
Ona radi na nižim nivoima od gravitacije,
08:43
which explains why you and I are smaller than stars or planets.
171
523523
3915
što objašnjava činjenicu zašto smo vi i ja
manji od zvezda i planeta.
E sad, koji su idealni uslovi za hemijske procese?
08:48
Now, what are the ideal conditions for chemistry?
172
528033
2294
08:50
What are the Goldilocks conditions?
173
530874
1770
Koji su Goldilokovi uslovi?
08:52
Well, first, you need energy,
174
532668
2357
Prvo, potrebna je energija,
ali ne previše.
08:55
but not too much.
175
535049
1187
08:56
In the center of a star, there's so much energy
176
536665
2255
U središtu zvezde, postoji previše energije,
08:58
that any atoms that combine will just get busted apart again.
177
538944
3142
tako da, ako se bilo koji atomi spoje, jednostavno će sagoreti i ponovo se razdvojiti.
Ali ne ni premalo.
09:02
But not too little.
178
542110
1126
09:03
In intergalactic space,
179
543642
1231
U intergalaktičkom prostoru, toliko je malo energije
09:04
there's so little energy that atoms can't combine.
180
544897
2883
da se atomi ne mogu spajati.
09:08
What you want is just the right amount,
181
548378
1858
Ono što je potrebno je prava količina,
09:10
and planets, it turns out, are just right,
182
550260
2000
a planete, ispostavilo se, su upravo idealne,
09:12
because they're close to stars, but not too close.
183
552284
2507
jer su blizu, ali ne ni preblizu zvezda.
09:15
You also need a great diversity of chemical elements,
184
555394
3595
Takođe je potrebna i raznolikost hemijskih elemenata,
i potrebna je tečnost kao što je voda.
09:19
and you need liquids, such as water.
185
559013
3008
Zašto?
09:22
Why?
186
562045
1047
09:23
Well, in gases, atoms move past each other so fast
187
563116
3872
Pa u gasovima, atomi prolaze jedni pored drugih toliko brzo
da se ne mogu spojiti.
09:27
that they can't hitch up.
188
567012
1453
09:28
In solids,
189
568950
1722
U čvrstim stanjima,
09:30
atoms are stuck together, they can't move.
190
570696
2540
atomi ne mogu da se pomeraju, zaglavljeni su.
09:33
In liquids,
191
573260
1718
U tečnostima,
09:35
they can cruise and cuddle
192
575002
3038
oni mogu da plutaju
i da se povezuju u molekule.
09:38
and link up to form molecules.
193
578064
2302
E sad, gde se pronalaze ovakvi Goldilokovi uslovi_
09:41
Now, where do you find such Goldilocks conditions?
194
581040
2355
09:43
Well, planets are great,
195
583934
1992
Planete su sjajne,
09:45
and our early Earth was almost perfect.
196
585950
3286
i naša rana Zemlja
je bila skoro savršena.
Bila je na idealnoj udaljenosti od njene zvezde
09:50
It was just the right distance from its star
197
590037
2048
da bi razvila velike okeane otvorenih voda.
09:52
to contain huge oceans of liquid water.
198
592109
2127
09:54
And deep beneath those oceans,
199
594260
1976
I duboko ispod tih okeana
09:56
at cracks in the Earth's crust,
200
596260
1976
u pukotinama kore,
09:58
you've got heat seeping up from inside the Earth,
201
598260
2976
imali ste toplotu koja je prodirala iz središta Zemlje,
10:01
and you've got a great diversity of elements.
202
601260
2127
i imali ste veliku raznolikost elemenata.
10:03
So at those deep oceanic vents,
203
603411
2546
Tako su se na tim dubokim okeanskim ventilima,
10:05
fantastic chemistry began to happen,
204
605981
2255
počeli dešavati fantastični hemijski procesi,
10:08
and atoms combined in all sorts of exotic combinations.
205
608260
3000
i atomi su se kombinovali u sve vrste egzotičnih kombinacija.
10:12
But of course, life is more than just exotic chemistry.
206
612260
4365
Ali, naravno, život je više
od egzotičnih hemijskih procesa.
Kako se stabilizuju
10:17
How do you stabilize those huge molecules
207
617054
3757
ti ogromni molekuli
10:20
that seem to be viable?
208
620835
1357
koji deluju kao sposobni za život?
10:22
Well, it's here that life introduces an entirely new trick.
209
622950
4356
Tu nam život predstavlja
jedan potpuno novi trik.
10:28
You don't stabilize the individual;
210
628220
2535
Ne stabilizuje se pojedinac;
10:30
you stabilize the template,
211
630779
2103
stabilizuje se šablon,
10:32
the thing that carries information,
212
632906
2105
deo koji nosi podatke,
a šablon ima mogućnost ponavljanja.
10:35
and you allow the template to copy itself.
213
635035
2217
A DNK je, naravno,
10:37
And DNA, of course, is the beautiful molecule
214
637276
3151
prelep molekul
10:40
that contains that information.
215
640451
2326
koji sadrži te podatke.
10:42
You'll be familiar with the double helix of DNA.
216
642801
2815
Bićete upoznati sa dvostrukim lancem DNK.
10:45
Each rung contains information.
217
645640
2516
Svaka prečka sadrži informacije.
Tako, DNK sadrži podatke o tome
10:48
So, DNA contains information about how to make living organisms.
218
648180
4573
kako se stvaraju živi organizmi.
I takođe kopira samu sebe.
10:53
And DNA also copies itself.
219
653315
1924
Stvara sopstvene kopije
10:55
So, it copies itself
220
655263
1206
10:56
and scatters the templates through the ocean.
221
656493
2682
i širi šablone okeanom.
Tako se informacije šire.
10:59
So the information spreads.
222
659199
1794
Primetili ste da je informacija postala deo naše priče.
11:01
Notice that information has become part of our story.
223
661017
2638
Pa ipak, prava lepota DNK molekula
11:04
The real beauty of DNA though is in its imperfections.
224
664137
3645
leži u njegovoj nesavršenosti.
11:07
As it copies itself, once in every billion rungs,
225
667806
3928
Kako stvara svoje kopije,
jednom na svakih milijardu prečki,
11:11
there tends to be an error.
226
671758
1745
dođe do greške.
11:13
And what that means is that DNA is, in effect, learning.
227
673527
4709
I to znači
da DNK, zapravo, uči.
11:18
It's accumulating new ways of making living organisms
228
678260
3320
Prikuplja nove načine stvaranja živih organizama
jer neke od tih grešaka funkcionišu.
11:21
because some of those errors work.
229
681604
1620
Znači DNK uči
11:23
So DNA's learning
230
683248
1198
11:24
and it's building greater diversity and greater complexity.
231
684470
3234
i stvara veću raznolikost i veću kompleksnost.
11:27
And we can see this happening over the last four billion years.
232
687728
3182
I vidimo da se ovo dešava proteklih četiri milijarde godina.
11:30
For most of that time of life on Earth,
233
690934
2175
Većinu tog vremena život na Zemlji
su činili relativno jednostavni organizmi --
11:33
living organisms have been relatively simple --
234
693133
2237
jednoćelijski organizmi.
11:35
single cells.
235
695394
1388
11:36
But they had great diversity, and, inside, great complexity.
236
696806
3430
Ali oni su bili jako raznovrsni,
i jako složene unutrašnjosti.
11:40
Then from about 600 to 800 million years ago,
237
700671
2904
Potom, pre oko 600 do 800 miliona godina,
11:43
multi-celled organisms appear.
238
703599
2091
pojavili su se višećelijski organizmi.
11:45
You get fungi, you get fish,
239
705714
2501
Gljive, ribe,
došle su biljke,
11:48
you get plants,
240
708239
1515
11:49
you get amphibia, you get reptiles,
241
709778
2711
potom vodozemci, zatim gmizavci,
11:52
and then, of course, you get the dinosaurs.
242
712513
2430
i naravno, dinosaurusi.
11:55
And occasionally, there are disasters.
243
715999
2509
I povremeno, dešavale su se katastrofe.
11:59
Sixty-five million years ago,
244
719586
2389
Pre 65 miliona godina,
12:01
an asteroid landed on Earth
245
721999
1964
asteroid je udario u Zemlju
12:03
near the Yucatan Peninsula,
246
723987
1790
blizu poluostrva Jukatan,
12:05
creating conditions equivalent to those of a nuclear war,
247
725801
2968
stvarajući uslove identične onima u nuklearnom ratu,
12:08
and the dinosaurs were wiped out.
248
728793
1889
i dinosaurusi su bili zbrisani.
Užasne vesti za dinosauruse.
12:11
Terrible news for the dinosaurs,
249
731166
3070
12:14
but great news for our mammalian ancestors,
250
734260
3755
Ali sjajne za naše pretke sisare
koji su procvetali
12:18
who flourished
251
738039
1197
12:19
in the niches left empty by the dinosaurs.
252
739260
3657
u staništima koja su ostala pusta.
12:22
And we human beings are part of that creative evolutionary pulse
253
742941
5055
A ljudska bića
su deo kreativnog evolutivnog procesa
koji je započeo pre 65 miliona godina
12:28
that began 65 million years ago
254
748020
2336
12:30
with the landing of an asteroid.
255
750380
1880
sa udarom asteroida.
12:33
Humans appeared about 200,000 years ago.
256
753796
2714
Ljudi su se pojavili pre oko 200,000 godina.
12:36
And I believe we count as a threshold in this great story.
257
756534
4348
I verujem da se računamo
kao sledeći nivo u ovoj priči.
12:40
Let me explain why.
258
760906
1207
Dozvolite da objasnim zašto.
12:42
We've seen that DNA learns in a sense,
259
762700
3031
Videli smo da DNK uči
12:45
it accumulates information.
260
765755
1787
sakupljajući podatke.
12:47
But it is so slow.
261
767566
1670
Ali proces je jako spor.
DNK skladišti podatke
12:50
DNA accumulates information through random errors,
262
770128
3472
putem nasumičnih grešaka
12:53
some of which just happen to work.
263
773624
2136
od kojih se samo za neke ispostavi da funkcionišu.
12:56
But DNA had actually generated a faster way of learning:
264
776490
2634
Ali DNK je razvio brži način učenja;
stvorio je organizme sa mozgovima,
12:59
it had produced organisms with brains,
265
779148
2778
13:01
and those organisms can learn in real time.
266
781950
3219
i ti organizmi mogu učiti u stvarnom vremenu.
Oni prikupljaju informacije, oni uče.
13:05
They accumulate information, they learn.
267
785193
2326
13:07
The sad thing is, when they die,
268
787543
2825
Tužna stvar je to što
kad umru, informacije umiru sa njima.
13:10
the information dies with them.
269
790392
1698
13:12
Now what makes humans different is human language.
270
792479
3987
Ono što ljude čini drugačijima
je ljudski jezik.
13:16
We are blessed with a language, a system of communication,
271
796490
2763
Blagosloveni smo jezikom, sistemom komunikacije,
toliko moćnim i toliko preciznim
13:19
so powerful and so precise
272
799277
2621
13:21
that we can share what we've learned with such precision
273
801922
3158
da možemo da delimo ono što smo naučili sa tolikom tačnošću
da se to može sakupljati u kolektivno pamćenje.
13:25
that it can accumulate in the collective memory.
274
805104
2889
A to znači
13:28
And that means
275
808017
1219
13:29
it can outlast the individuals who learned that information,
276
809260
3779
da može da nadživi pojedince koji su naučili taj podatak
i može se sakupljati iz generacije u generaciju.
13:33
and it can accumulate from generation to generation.
277
813063
3173
13:36
And that's why, as a species, we're so creative and so powerful,
278
816260
4056
I to je razlog zbog kog smo, kao vrsta, toliko kreativni
i toliko moćni
13:40
and that's why we have a history.
279
820340
2056
i zbog toga imamo istoriju.
Izgleda da smo jedina vrsta tokom ove četiri milijarde godina
13:43
We seem to be the only species in four billion years
280
823015
3301
koja ima ovaj dar.
13:46
to have this gift.
281
826340
1242
Ja zovem ovu sposobnost
13:48
I call this ability collective learning.
282
828057
3565
kolektivnim učenjem.
13:51
It's what makes us different.
283
831995
1389
To je ono što nas čini drugačijim.
13:53
We can see it at work in the earliest stages of human history.
284
833686
3550
Možemo videti to na poslu
u najranijim periodima ljudske istorije.
13:57
We evolved as a species in the savanna lands of Africa,
285
837949
3287
Evoluirali smo kao vrsta
u savanama Afrike,
14:01
but then you see humans migrating into new environments,
286
841260
3460
ali smo onda kao vrsta migrirali u nova okuženja --
14:04
into desert lands, into jungles,
287
844744
2150
u pustinje, džungle,
14:06
into the Ice Age tundra of Siberia --
288
846918
2436
u ledene tundre Sibira --
teška, teška okruženja --
14:09
tough, tough environment --
289
849378
1445
14:10
into the Americas, into Australasia.
290
850847
2333
u Ameriku, Australaziju.
Svaka migracija razvijala je učenje --
14:13
Each migration involved learning --
291
853204
2037
učenje novih načina korišćenja sredine,
14:15
learning new ways of exploiting the environment,
292
855265
2483
14:17
new ways of dealing with their surroundings.
293
857772
2174
novih načina odnosa sa sredinom.
14:19
Then 10,000 years ago,
294
859970
1816
Potom, pre 10,000 godina,
14:21
exploiting a sudden change in global climate
295
861810
2995
koristeći nagle globalne klimatske promene
sa krajem poslednjeg ledenog doba,
14:24
with the end of the last ice age,
296
864829
1572
ljudi su naučili da se bave agrikulturom.
14:26
humans learned to farm.
297
866425
1581
14:28
Farming was an energy bonanza.
298
868623
2436
Agrikultura je bila energetsko bogatstvo.
Koristeći tu energiju,
14:31
And exploiting that energy, human populations multiplied.
299
871083
3827
ljudska populacija se uvećavala.
14:34
Human societies got larger, denser, more interconnected.
300
874934
3587
Ljudska društva su postajala veća, gušće naseljena,
više povezana.
I otprilike pre 500 godina,
14:39
And then from about 500 years ago,
301
879101
3351
14:42
humans began to link up globally
302
882476
2039
ljudi su počeli da se globalno povezuju
14:44
through shipping, through trains,
303
884539
2381
preko brodova, vozova,
14:46
through telegraph, through the Internet,
304
886944
2292
preko telegrafa, interneta,
14:49
until now we seem to form a single global brain
305
889260
5191
do sada kada možemo videti kako se stvara
jedinstven globalni mozak
od skoro sedam milijardi pojedinaca.
14:54
of almost seven billion individuals.
306
894475
2132
I taj mozak uči ogromnom brzinom.
14:56
And that brain is learning at warp speed.
307
896631
3162
15:00
And in the last 200 years, something else has happened.
308
900572
2572
I u poslednjih 200 godina, još nešto se desilo:
naišli smo na još jedno energetsko bogatstvo
15:03
We've stumbled on another energy bonanza
309
903168
2666
fosilna goriva.
15:05
in fossil fuels.
310
905858
1127
Fosilna goriva i kolektivno učenje zajedno
15:07
So fossil fuels and collective learning together
311
907009
2703
15:09
explain the staggering complexity we see around us.
312
909736
3524
objašnjavaju zapanjujuću kompleksnost
koja nas okružuje.
15:16
So --
313
916505
1000
I tako, eto nas ovde
15:18
Here we are,
314
918668
1317
natrag u kongresni centar.
15:20
back at the convention center.
315
920009
1524
15:21
We've been on a journey, a return journey, of 13.7 billion years.
316
921557
4706
Bili smo na putovanju, putovanju u prošlost,
unazad 13.7 milijardi godina.
15:26
I hope you agree this is a powerful story.
317
926967
2469
Nadam se da ćete se složiti da je ovo jedna moćna priča.
15:29
And it's a story in which humans play an astonishing and creative role.
318
929460
4665
I to je priča u kojoj ljudi
igraju zapanjujuću i kreativnu ulogu.
15:34
But it also contains warnings.
319
934466
2215
Ali ona sadrži i upozorenja.
15:37
Collective learning is a very, very powerful force,
320
937474
4333
Kolektivno učenje je vrlo, vrlo moćna sila,
15:41
and it's not clear that we humans are in charge of it.
321
941831
4405
I nije jasno
da je mi, ljudi, u potpunosti kontrolišemo.
Sećam se vrlo živo da sam kao dete odrastao u Engleskoj,
15:47
I remember very vividly as a child growing up in England,
322
947123
3069
za vreme Kubanske raketne krize.
15:50
living through the Cuban Missile Crisis.
323
950216
2020
15:52
For a few days, the entire biosphere
324
952847
3611
U roku od nekoliko dana,
čitava biosfera
15:56
seemed to be on the verge of destruction.
325
956482
2299
delovala je kao da je na ivici uništenja.
15:59
And the same weapons are still here,
326
959474
3165
A isto oružje i dalje je tu,
16:02
and they are still armed.
327
962663
1573
oni su i dalje naoružani.
I ako uspemo da zaobiđemo tu zamku,
16:05
If we avoid that trap, others are waiting for us.
328
965004
3232
druge i dalje čekaju na nas.
16:08
We're burning fossil fuels at such a rate
329
968647
2589
Sagorevamo fosilna goriva u tolikoj količini
16:11
that we seem to be undermining the Goldilocks conditions
330
971260
3411
da izgleda da podrivamo Goldilokove uslove
16:14
that made it possible for human civilizations
331
974695
2228
koji omogućavaju ljudskoj civilizaciji
16:16
to flourish over the last 10,000 years.
332
976947
3082
da cveta preko 10,000 godina.
16:20
So what big history can do
333
980633
2276
Ono šta velika istorija može da uradi
16:22
is show us the nature of our complexity and fragility
334
982933
3321
je da nam pokaže prirodu naše kompleksnosti i ranjivosti
i opasnosti sa kojima se suočavamo,
16:26
and the dangers that face us,
335
986278
1924
ali takođe nam može pokazati
16:28
but it can also show us our power with collective learning.
336
988226
3580
moć koju ima kolektivno učenje.
16:32
And now, finally --
337
992586
1952
I sada, najzad,
16:35
this is what I want.
338
995657
2155
ono što ja želim.
16:39
I want my grandson, Daniel,
339
999448
3032
Ja želim da moj unuk Danijel
16:42
and his friends and his generation,
340
1002504
2757
i njegovi prijatelji i njegova generacija,
u čitavom svetu,
16:45
throughout the world,
341
1005285
1793
znaju priču velike istorije,
16:47
to know the story of big history,
342
1007102
2840
16:49
and to know it so well
343
1009966
2039
i da je znaju toliko dobro
da razumeju
16:52
that they understand both the challenges that face us
344
1012029
3666
i izazove sa kojima se suočavamo,
16:55
and the opportunities that face us.
345
1015719
2517
ali i mogućnosti koje su pred nama.
16:58
And that's why a group of us
346
1018260
1880
I zato grupa nas
17:00
are building a free, online syllabus
347
1020164
3012
gradi besplatan nastavni program na mreži
o velikoj istoriji
17:03
in big history
348
1023200
1318
17:04
for high-school students throughout the world.
349
1024542
2151
za srednjoškolce u čitavom svetu.
Verujemo da će velika istorija
17:07
We believe that big history
350
1027225
2436
17:09
will be a vital intellectual tool for them,
351
1029685
2551
biti osnovno intelektualno sredstvo za njih,
17:12
as Daniel and his generation
352
1032260
2843
kako se Danijel i njegova generacija
17:15
face the huge challenges
353
1035127
2348
budu suočavali sa velikim izazovima,
17:17
and also the huge opportunities
354
1037499
2055
a takođe i sa velikim mogućnostima
17:19
ahead of them at this threshold moment
355
1039578
3455
koje su pred njima u ovom novom trenutku
u istoriji ove prelepe planete.
17:23
in the history of our beautiful planet.
356
1043057
3179
17:26
I thank you for your attention.
357
1046993
1548
Zahvaljujem vam se na pažnji.
