The great texts of the ancient world
0
15731
2484
Oldtidens store skrifter
00:18
don't survive to us in their original form.
1
18215
3315
er ikke tilgængelige i deres oprindelige form.
00:21
They survive because medieval scribes copied them
2
21530
3519
De er tilgængelige, fordi middelalderens skrivere kopierede dem,
00:25
and copied them and copied them.
3
25049
1999
igen og igen.
00:27
And so it is with Archimedes,
4
27048
2650
Således er det også med Arkimedes,
00:29
the great Greek mathematician.
5
29698
1766
den store græske matematiker.
00:31
Everything we know about Archimedes as a mathematician
6
31464
3002
Alt som vi ved om Arkimedes som matematiker,
00:34
we know about because of just three books,
7
34466
2698
ved vi fra blot tre bøger,
00:37
and they're called A, B and C.
8
37164
1916
som hedder A, B og C.
00:39
And A was lost by an Italian humanist in 1564.
9
39080
4833
A blev smidt væk af en italiensk humanist i 1564.
00:43
And B was last heard of in the Pope's Library
10
43913
2803
B hørte man sidst om i pavens bibliotek
00:46
about a hundred miles north of Rome in Viterbo in 1311.
11
46716
5832
cirka 160 kilometer nord for Rom i Viterbo i 1311.
00:52
Now Codex C was only discovered in 1906,
12
52548
4297
Kodeks C blev først fundet i 1906,
00:56
and it landed on my desk in Baltimore
13
56845
2549
og det havnede på mit skrivebord i Baltimore
00:59
on the 19th of January, 1999.
14
59394
4126
den 19. januar 1999.
01:03
And this is Codex C here.
15
63520
2418
Dette er Kodeks C.
01:05
Now Codex C is actually buried in this book.
16
65938
5169
Kodeks C er faktisk gemt i denne bog.
01:11
It's buried treasure.
17
71107
1450
Det er en gemt skat.
01:12
Because this book is actually a prayer book.
18
72557
2335
Denne bog er nemlig faktisk en bønnebog.
01:14
It was finished by a guy called Johannes Myrones
19
74892
2964
Den blev afsluttet af en fyr ved navn Ioannes Myronas
01:17
on the 14th of April, 1229.
20
77856
3617
den 14. april 1229.
01:21
And to make his prayer book he used parchment.
21
81473
2485
For at lave sin bønnebog brugte han pergament.
01:23
But he didn't use new parchment,
22
83958
2415
Men han brugte ikke nyt pergament,
01:26
he used parchment recycled from earlier manuscripts,
23
86373
3314
han brugte pergament, som var genbrugt fra tidligere manuskripter,
01:29
and there were seven of them.
24
89687
1737
som der var syv af.
01:31
And Archimedes Codex C was just one of those seven.
25
91424
3483
Arkimedes' kodeks C var blot et af disse syv.
01:34
He took apart the Archimedes manuscript and the other seven manuscripts.
26
94907
5467
Han skilte Arkimedes' og de syv andre manuskripter ad.
01:40
He erased all of their texts,
27
100374
3383
Han slettede al skriften,
01:43
and then he cut the sheets down in the middle,
28
103757
2418
hvorefter han skar arkene over på midten,
01:46
he shuffled them up,
29
106175
2244
han blandede dem,
01:48
and he rotated them 90 degrees,
30
108419
1918
og han roterede dem 90 grader,
01:50
and he wrote prayers on top of these books.
31
110337
2052
og han skrev bønner på dem.
01:52
And essentially these seven manuscripts
32
112389
1697
Disse syv manuskripter
01:54
disappeared for 700 years, and we have a prayer book.
33
114086
4348
forsvandt nu i 700 år, og vi har en bønnebog.
01:58
The prayer book was discovered by this guy,
34
118434
3249
Bønnebogen blev fundet af denne fyr,
02:01
Johan Ludvig Heiberg, in 1906.
35
121683
2727
Johan Ludvig Heiberg, i 1906.
02:04
And with just a magnifying glass,
36
124410
1441
Kun ved hjælp af en lup
02:05
he transcribed as much of the text as he could.
37
125851
2884
tydede han så meget af teksten, som han kunne.
02:08
And the thing is that he found two texts in this manuscript
38
128735
3182
Sagen er, at han fandt to tekster i dette manuskript,
02:11
that were unique texts.
39
131917
1768
som var unikke.
02:13
They weren't in A and B at all;
40
133685
1600
De fandtes slet ikke i A og B;
02:15
they were completely new texts by Archimedes,
41
135285
1698
De var helt nye tekster af Arkimedes,
02:16
and they were called "The Method" and "The Stomachion."
42
136983
3235
og de hedder "Metoden" og "Stomachion".
02:20
And it became a world famous manuscript.
43
140218
2269
Manuskriptet blev verdensberømt.
02:22
Now it should be clear by now
44
142487
1815
På dette tidspunkt skal det forstås,
02:24
that this book is in bad condition.
45
144302
2714
at denne bog er i dårlig stand.
02:27
It got in worse condition in the 20th century
46
147016
3470
Dens stand forværredes i det 20. århundrede,
02:30
after Heiberg saw it.
47
150486
1732
efter Heiberg så den.
02:32
Forgeries were painted over it,
48
152218
1517
Falsknerier blev malet i den,
02:33
and it suffered very badly from mold.
49
153735
3083
og den led frygteligt af mug.
02:36
This book is the definition of a write-off.
50
156818
3750
Denne bog er selve definitionen af skrammel.
02:40
It's the sort of book
51
160568
1734
Det er den slags bog,
02:42
that you thought would be in an institution.
52
162302
2665
som burde være på en institution.
02:44
But it's not in an institution,
53
164967
2186
Men den er ikke på en institution,
02:47
it was bought by a private owner in 1998.
54
167153
4632
den blev købt af en privat ejer i 1998.
02:51
Why did he buy this book?
55
171785
1750
Hvorfor købte han bogen?
02:53
Because he wanted to make that which was fragile safe.
56
173535
3537
Fordi han ville redde det skrøbelige.
02:57
He wanted to make that which was unique ubiquitous.
57
177072
3246
Han ville gøre det unikke universelt tilgængeligt.
03:00
He wanted to make that which was expensive free.
58
180318
4666
Han ville gøre det dyre gratis.
03:04
And he wanted to do this as a matter of principle.
59
184984
3135
Dette gjorde han som en principsag.
03:08
Because not many people are really going to read Archimedes in ancient Greek,
60
188119
4532
Fordi mange mennesker ville aldrig læse Arkimedes på oldgræsk,
03:12
but they should have the chance to do it.
61
192651
2684
men de burde have muligheden for det.
03:15
So he gathered around himself the friends of Archimedes,
62
195335
3299
Så han samlede Arkimedes' venner,
03:18
and he promised to pay for all the work.
63
198634
2136
og lovede at han ville betale for alt arbejdet.
03:20
And it was an expensive job,
64
200770
1698
Det var et dyrt arbejde,
03:22
but actually it wouldn't be as much as you think
65
202468
3470
men det kom ikke til at koste så meget, som man kunne tro,
03:25
because these people, they didn't come from money,
66
205938
2165
da disse folk ikke kom for pengene,
03:28
they came from Archimedes.
67
208103
1819
de kom for Arkimedes.
03:29
And they came from all sorts of different backgrounds.
68
209922
1716
Og de havde alle mulige baggrunde.
03:31
They came from particle physics,
69
211638
2183
De kom fra partikelfysikken,
03:33
they came from classical philology,
70
213821
1566
de kom fra klassisk filologi,
03:35
they came from book conservation,
71
215387
1968
de kom fra bog-konservering,
03:37
they came from ancient mathematics,
72
217355
2582
de kom fra oldtidens matematik,
03:39
they came from data management,
73
219937
1917
de kom fra data-styring,
03:41
they came from scientific imaging and program management.
74
221854
2917
de kom fra videnskabelig billedbehandling og program-styring.
03:44
And they got together to work on this manuscript.
75
224771
3556
De fandt sammen for at arbejde på dette manuskript.
03:48
The first problem was a conservation problem.
76
228327
3811
Det første problem var konserveringen.
03:52
And this is the sort of thing that we had to deal with:
77
232138
2433
Dette er et eksempel på hvad vi havde at gøre med:
03:54
There was glue on the spine of the book.
78
234571
2200
Der var lim på bogens ryg.
03:56
And if you look at this photograph carefully,
79
236771
2201
Hvis I ser nøje efter på billedet,
03:58
the bottom half of this is rather brown.
80
238972
2048
er den nederste halvdel af bogen ganske brun.
04:01
And that glue is hide glue.
81
241020
1368
Limen er udvundet af dyrehud.
04:02
Now if you're a conservator,
82
242388
1385
Hvis man er konservator,
04:03
you can take off this glue reasonably easily.
83
243773
2132
kan man relativt nemt fjerne denne slags lim.
04:05
The top half is Elmer's wood glue.
84
245905
3365
På den øverste del har man brugt trælim.
04:09
It's polyvinyl acetate emulsion
85
249270
2117
Det er en emulsion af polyvinylacetat,
04:11
that doesn't dissolve in water once it's dry.
86
251387
2667
som ikke kan opløses i vand, når den først er tør.
04:14
And it's much tougher than the parchment that it was written on.
87
254054
3166
Den er meget sejere, end pergamentet den blev brugt på.
04:17
And so before we could start imaging Archimedes,
88
257220
3351
Så før vi kunne begynde at scanne Arkimedes,
04:20
we had to take this book apart.
89
260571
1449
var vi nødt til at skille bogen ad.
04:22
So it took four years to take apart.
90
262020
2851
Det tog fire år at skille bogen ad.
04:24
And this is a rare action shot, ladies and gentlemen.
91
264871
3533
Dette, mine damer og herrer, er et sjældent billede af processen.
04:28
(Laughter)
92
268404
2771
(Latter)
04:31
Another thing is that we had to get rid of all the wax,
93
271175
4266
Derefter måtte vi fjerne al voksen,
04:35
because this was used in the liturgical services
94
275441
2235
da man brugte det under gudstjenesterne
04:37
of the Greek Orthodox Church
95
277676
1741
i den græsk-ortodokse kirke;
04:39
and they'd used candle wax.
96
279417
1311
og man brugte voks fra lys.
04:40
And the candle wax was dirty,
97
280728
1863
Voksen fra lysene var beskidt,
04:42
and we couldn't image through the wax.
98
282591
1233
og vi kunne ikke scanne igennem voksen.
04:43
So very carefully we had to mechanically scrape off all the wax.
99
283824
3335
Så med den største forsigtighed måtte vi mekanisk skrabe al voksen af.
04:47
It's hard to tell you exactly
100
287159
1902
Det er svært at beskrive præcist,
04:49
how bad this condition of this book is,
101
289061
2714
hvor dårlig en stand bogen er i,
04:51
but it came out in little bits very often.
102
291775
2766
men ofte kom den i små stykker.
04:54
And normally in a book, you wouldn't worry about the little bits,
103
294541
2350
Under normale forhold ville man ikke bruge energi på de små stykker,
04:56
but these little bits might contain unique Archimedes text.
104
296891
3000
men disse små stykker kunne indeholde unik tekst af Arkimedes.
04:59
So, tiny fragments
105
299891
2299
Så det lykkedes os faktisk,
05:02
we actually managed to put back in the right place.
106
302190
4741
at sætte bittesmå fragmenter på plads.
05:06
Then, having done that, we started to image the manuscript.
107
306931
3710
Da vi havde gjort det, kunne vi begynde scanningen af manuskriptet.
05:10
And we imaged the manuscript
108
310641
1500
Vi scannede manuskriptet
05:12
in 14 different wavebands of light.
109
312141
2028
under 14 forskellige lysfrekvenser.
05:14
Because if you look at something in different wavebands of light,
110
314169
3906
Fordi hvis man ser på noget under forskellige lysfrekvenser,
05:18
you see different things.
111
318075
1216
ser man forskellige ting.
05:19
And here is an image of a page
112
319291
1567
Her er et billede af en side
05:20
imaged in 14 different wavebands of light.
113
320858
2517
scannet under 14 forskellige lysfrekvenser.
05:23
But none of them worked.
114
323375
2133
Men ingen af dem virkede.
05:25
So what we did was we processed the images together,
115
325508
4417
Så vi gjorde det, at vi scannede billederne sammen,
05:29
and we put two images into one blank screen.
116
329925
3300
og vi satte to billeder sammen på en blank skærm.
05:33
And here are two different images of the Archimedes manuscript.
117
333225
2833
Her er to forskellige billeder af Arkimedes' manuskript.
05:36
And the image on the left
118
336058
1816
Billedet til venstre
05:37
is the normal red image.
119
337874
1351
er det normale røde billede.
05:39
And the image on the right is an ultraviolet image.
120
339225
1912
Billedet til højre er et ultraviolet billede.
05:41
And in the image on the right
121
341137
1140
På billedet til højre
05:42
you might be able to see some of the Archimedes writing.
122
342277
2448
kan I måske se noget af Arkimedes' skrift.
05:44
If you merge them together into one digital canvas,
123
344725
2982
Hvis man samler dem på et digitalt lærred,
05:47
the parchment is bright in both images
124
347707
2818
er pergamentet lyst på begge billeder,
05:50
and it comes out bright.
125
350525
1875
og det fremstår som lyst.
05:52
The prayer book is dark in both images
126
352400
3016
Bønnebogen er mørk på begge billeder,
05:55
and it comes out dark.
127
355416
1697
og den fremstår som mørk.
05:57
The Archimedes text is dark in one image and bright in another.
128
357113
3351
Arkimedes' skrift er mørk på et billede og lyst på et andet.
06:00
And it'll come out dark but red,
129
360464
2400
Den fremstår som mørkerød,
06:02
and then you can start to read it rather clearly.
130
362864
2267
og så kan man begynde at læse den ret klart.
06:05
And that's what it looks like.
131
365131
2842
Sådan ser det ud.
06:07
Now that's a before and after image,
132
367973
3342
Dette er et før og efter-billede,
06:11
but you don't read the image on the screen like that.
133
371315
2982
men sådan læser man det ikke på skærmen.
06:14
You zoom in and you zoom in
134
374297
2619
Man zoomer ind,
06:16
and you zoom in and you zoom in,
135
376916
3548
igen og igen,
06:20
and you can just read it now.
136
380464
2068
og nu kan man bare læse det.
06:22
(Applause)
137
382532
6348
(Bifald)
06:28
If you process the same two images in a different way,
138
388880
3580
Hvis man fremkalder de samme to billeder på en anden måde,
06:32
you can actually get rid of the prayer book text.
139
392460
2570
kan man faktisk slippe af med bønnebogens skrift.
06:35
And this is terribly important,
140
395030
1018
Dette er meget vigtigt,
06:36
because the diagrams in the manuscript
141
396048
2983
fordi diagrammerne i manuskriptet
06:39
are the unique source for the diagrams
142
399031
2467
er eneste kilde for diagrammerne,
06:41
that Archimedes drew in the sand in the fourth century B.C.
143
401498
2817
som Arkimedes tegnede i sandet i det 4. århundrede før vor tidsregning.
06:44
And there we are, I can give them to you.
144
404315
3039
Her er de, jeg viser dem til jer.
06:47
With this kind of imaging --
145
407354
2344
Med denne type scanning --
06:49
this kind of infrared, ultraviolet, invisible light imaging --
146
409698
2666
denne slags infrarøde, ultraviolette, usynligt lys-scanning --
06:52
we were never going to image through the gold ground forgeries.
147
412364
2600
kunne vi aldrig scanne igennem de guld-baserede falsknerier.
06:54
How were we going to do that?
148
414964
1853
Hvordan skulle vi kunne gøre det?
06:56
Well we took the manuscript,
149
416817
1963
Vi tog manuskriptet,
06:58
and we decided to image it in X-ray fluorescence imaging.
150
418780
4287
og vi besluttede at scanne det ved hjælp af røntgenfluorescens.
07:03
So an X-ray comes in in the diagram on the left
151
423067
3014
En røntgen-stråle kommer ind på diagrammet til venstre,
07:06
and it knocks out an electron from the inner shell of an atom.
152
426081
3852
og det banker en elektron løs fra et atoms inderste bane.
07:09
And that electron disappears.
153
429933
1998
Denne elektron forsvinder.
07:11
And as it disappears, an electron from a shell farther out
154
431931
3635
Som den forsvinder, hopper en elektron fra en ydre bane,
07:15
jumps in and takes its place.
155
435566
2482
ind og tager dens plads.
07:18
And when it takes its place,
156
438048
1433
Når den tager dens plads,
07:19
it sheds electromagnetic radiation.
157
439481
2834
giver den elektromagnetisk stråling fra sig.
07:22
It sheds an X-ray.
158
442315
1432
Den afgiver en røntgenstråle.
07:23
And this X-ray is specific in its wavelength
159
443747
2651
Denne røntgenstråle har en særlig frekvens
07:26
to the atom that it hits.
160
446398
1882
for det atom, som den rammer.
07:28
And what we wanted to get
161
448280
2168
Det som vi sigtede efter
07:30
was the iron.
162
450448
1733
var jern.
07:32
Because the ink was written in iron.
163
452181
1867
Fordi blækket var lavet af jern.
07:34
And if we can map
164
454048
1683
Hvis vi kan kortlægge,
07:35
where this X-ray that comes out, where it comes from,
165
455731
2584
hvor denne røntgenstråle kommer fra,
07:38
we can map all the iron on the page,
166
458315
2066
kan vi kortlægge alt jernet på siden,
07:40
then theoretically we can read the image.
167
460381
2599
og så kan vi, teoretisk set, læse billedet.
07:42
The thing is that you need a very powerful light source to do this.
168
462980
4335
Sagen er, at man skal bruge en meget kraftig lyskilde for at kunne gøre det.
07:47
So we took it to the Stanford Synchrotron Radiation Laboratory
169
467315
3374
Så vi bragte manuskriptet til Stanfords SSRL
07:50
in California,
170
470689
1442
i Californien,
07:52
which is a particle accelerator.
171
472131
1568
som er en partikel-accelerator.
07:53
Electrons go around one way,
172
473699
1732
Elektroner kommer fra den ene side,
07:55
positrons go around the other.
173
475431
1617
og positroner kommer fra den anden.
07:57
They meet in the middle,
174
477048
1316
De mødes på midten,
07:58
and they create subatomic particles
175
478364
2436
hvor de skaber sub-atomare partikler
08:00
like the charm quark and the tau lepton.
176
480800
2230
som charm-kvarken og tau-leptonen.
08:03
Now we weren't actually going to put Archimedes in that beam.
177
483030
3022
Vi ville ikke lægge manuskriptet ind i strålen.
08:06
But as the electrons go round at the speed of light,
178
486052
3548
Men når elektronerne bevæger sig rundt med lysets hastighed,
08:09
they shed X-rays.
179
489600
1267
afgiver de røntgenstråler.
08:10
And this is the most powerful light source in the solar system.
180
490867
2650
Dette er den stærkeste lyskilde i solsystemet.
08:13
This is called synchrotron radiation,
181
493517
1949
Det kaldes synkrotron-stråling,
08:15
and it's normally used to look at things
182
495466
1818
og man bruger det normalt til at se på ting
08:17
like proteins and that sort of thing.
183
497284
1667
som proteiner og den slags.
08:18
But we wanted it to look at atoms, at iron atoms,
184
498951
3997
Men vi ville bruge den til at se på atomer, på jern-atomer,
08:22
so that we could read the page from before and after.
185
502948
2869
så vi kunne læse siden fra før og efter.
08:25
And lo and behold, we found that we could do it.
186
505817
2298
Og se nu her, vi opdagede at det var muligt.
08:28
It took about 17 minutes to do a single page.
187
508115
3448
Hver side tog 17 minutter at fuldføre.
08:31
So what did we discover?
188
511563
2655
Så, hvad fandt vi ud af?
08:34
Well one of the unique texts in Archimedes
189
514218
2182
En af de unikke skrifter i manuskriptet
08:36
is called "The Stomachion."
190
516400
1803
hedder "Stomachion"
08:38
And this didn't exist in Codices A and B.
191
518203
2414
Denne fandtes ikke i kodeks A og B.
08:40
And we knew that it involved this square.
192
520617
2419
Vi vidste, at den havde at gøre med denne firkant.
08:43
And this is a perfect square,
193
523036
1793
Det er et perfekt kvadrat,
08:44
and it's divided into 14 bits.
194
524829
2021
og det er opdelt i 14 stykker.
08:46
But no one knew what Archimedes was doing with these 14 bits.
195
526850
2783
Men ingen vidste hvad Arkimedes lavede med disse 14 stykker.
08:49
And now we think we know.
196
529633
2184
Men nu tror vi, at vi ved det.
08:51
He was trying to work out
197
531817
1767
Han prøvede at finde ud af,
08:53
how many ways you can recombine those 14 bits
198
533584
2533
hvor mange måder man kunne sætte disse 14 stykker sammen på
08:56
and still make a perfect square.
199
536117
2327
og stadig have et perfekt kvadrat.
08:58
Anyone want to guess the answer?
200
538444
3502
Kan I gætte svaret?
09:01
It's 17,152 divided into 536 families.
201
541946
5362
Det er 17.152 fordelt på 536 familier.
09:07
And the important point about this
202
547308
2367
Det vigtige med det her er,
09:09
is that it's the earliest study in combinatorics in mathematics.
203
549675
3714
at det er det tidligste studie i kombinatorik i matematikken.
09:13
And combinatorics is a wonderful and interesting branch of mathematics.
204
553389
3764
Kombinatorik er en vidunderlig og interessant matematisk disciplin.
09:17
The really astonishing thing though about this manuscript
205
557153
3235
Det virkeligt forbløffende ved dette manuskript er,
09:20
is that we looked at the other manuscripts
206
560388
2369
at vi så på de andre manuskripter,
09:22
that the palimpsester had made,
207
562757
1418
som palimpsest-mageren havde lavet,
09:24
the scribe had made his book out of,
208
564175
2566
som skriveren havde lavet denne bog af,
09:26
and one of them was a manuscript containing text by Hyperides.
209
566741
2932
og et af dem var et manuskript indeholdende tekst af Hypereides.
09:29
Now Hyperides was an Athenian orator from the fourth century B.C.
210
569673
4368
Hypereides var en taler fra Athen i det 4. århundrede f.v.t.
09:34
He was an exact contemporary of Demosthenes.
211
574041
2417
Han levede på samme tid som Demosthenes.
09:36
And in 338 B.C. he and Demosthenes together
212
576458
4399
I 338 f.v.t. bestemte han og Demosthenes
09:40
decided that they wanted to stand up
213
580857
1684
sig for at gøre modstand mod
09:42
to the military might of Philip of Macedon.
214
582541
2000
Filip 2. af Makedoniens militære magt.
09:44
So Athens and Thebes went out to fight Philip of Macedon.
215
584541
3649
Så Athen og Theben gik i krig mod Filip 2. af Makedonien.
09:48
This was a bad idea,
216
588190
1268
Det var en dårlig idé,
09:49
because Philip of Macedon had a son called Alexander the Great,
217
589458
3433
for Filip 2. af Makedonien havde en søn ved navn Alexander den Store,
09:52
and they lost the battle of Chaeronea.
218
592891
2283
og de tabte slaget ved Chaeronea.
09:55
Alexander the Great went on to conquer the known world;
219
595174
2718
Alexander den Store endte med at erobre den kendte verden;
09:57
Hyperides found himself on trial for treason.
220
597892
2750
Hypereides blev retsforfulgt for forræderi.
10:00
And this is the speech that he gave when he was on trial --
221
600642
3600
Dette er hans forvarstale fra retssagen --
10:04
and it's a great speech:
222
604242
1148
og det er en stor tale:
10:05
"Best of all," he says, "is to win.
223
605390
2268
"Det bedste," siger han, "er at vinde.
10:07
But if you can't win,
224
607658
1734
Men hvis man ikke kan vinde,
10:09
then you should fight for a noble cause,
225
609392
2041
bør man kæmpe for en ædel sag,
10:11
because then you'll be remembered.
226
611433
1575
for så vil man blive husket.
10:13
Consider the Spartans.
227
613008
1598
Tag spartanerne som eksempel.
10:14
They won enumerable victories,
228
614606
1868
De vandt utallige sejre,
10:16
but no one remembers what they are
229
616474
1832
men ingen husker dem,
10:18
because they were all fought for selfish ends.
230
618306
2135
fordi de alle blev udkæmpet af egoistiske grunde.
10:20
The one battle that the Spartans fought that everybody remembers
231
620441
3566
Det eneste slag, som spartanerne deltog i, som alle kan huske,
10:24
is the the battle of Thermopylae
232
624007
1716
er slaget ved Thermopylæ,
10:25
where they were butchered to a man,
233
625723
2003
hvor de alle blev slagtet,
10:27
but fought for the freedom of Greece."
234
627726
1932
men kæmpede for Grækenlands frihed."
10:29
It was such a great speech
235
629658
2265
Talen var så god,
10:31
that the Athenian law courts let him off.
236
631923
3735
at retten i Athen lod ham slippe uden straf.
10:35
He lived for another 10 years,
237
635658
2066
Han levede i 10 år til,
10:37
then the Macedonian faction caught up with him.
238
637724
2651
før den makedonske hær fangede ham.
10:40
They cut out his tongue in mockery of his oratory,
239
640375
2584
De skar hans tunge af for at spotte hans tale,
10:42
and no one knows what they did with his body.
240
642959
3431
og ingen ved, hvad de gjorde med liget.
10:46
So this is the discovery of a lost voice from antiquity,
241
646390
3151
Så dette er opdagelsen af en glemt stemme fra antikken,
10:49
speaking to us, not from the grave,
242
649541
1982
som taler til os, ikke fra graven,
10:51
because his grave doesn't exist,
243
651523
1478
fordi hans grav findes ikke,
10:53
but from the Athenian law courts.
244
653001
1773
men fra retten i Athen.
10:54
Now I should say at this point
245
654774
1649
På dette tidspunkt bør jeg nævne,
10:56
that normally when you're looking
246
656423
2767
at man normalt ikke, når man ser på
10:59
at medieval manuscripts that have been scraped off,
247
659190
1996
manuskripter fra middelalderen, som er blevet skrabet,
11:01
you don't find unique texts.
248
661186
1486
finder unikke skrifter.
11:02
And to find two in one manuscript is really something.
249
662672
3102
Så at finde to i ét manuskript er noget særligt.
11:05
To find three is completely weird.
250
665774
3217
At finde tre er fuldstændig mærkeligt.
11:08
And we found three.
251
668991
1681
Vi fandt tre.
11:10
Aristotle's "Categories"
252
670672
1266
Aristoteles' "Kategorier"
11:11
is one of the foundational texts of Western philosophy.
253
671938
2453
er en af de grundlæggende skrifter i den vestlige verdens filosofi.
11:14
And we found a third century A.D. commentary on it,
254
674391
4416
Vi fandt en kommentar om den fra det 3. århundrede.
11:18
possibly by Galen and probably by Porphyry.
255
678807
3184
Muligvis af Galén og sandsynligvis af Porfyr.
11:21
Now all this data that we collected,
256
681991
2198
Al det data som vi har samlet,
11:24
all the images, all the raw images,
257
684189
2535
alle billederne, alle de rå billeder,
11:26
all the transcriptions that we made and that sort of thing
258
686724
2350
alle transskriptionerne, som vi lavede, og den slags
11:29
have been put online under a Creative Commons license
259
689074
3486
er lagt på nettet under en Creative Commons licens,
11:32
for anyone to use for any commercial purpose.
260
692560
2914
så det kan bruges af alle til ethvert kommercielt formål.
11:35
(Applause)
261
695474
6533
(Bifald)
11:42
Why did the owner of the manuscript do this?
262
702007
3304
Hvorfor gjorde manuskriptets ejer dette?
11:45
He did this because he understands data as well as books.
263
705311
3746
Det gjorde han, fordi han forstår data såvel som bøger.
11:49
Now the thing to do with books,
264
709057
1335
Det man skal gøre med bøger,
11:50
if you want to ensure their long-term utility,
265
710392
2131
hvis man vil sikre deres langvarige brug,
11:52
is to hide them away in closets
266
712523
2216
er at gemme dem i skabe,
11:54
and let very few people look at them.
267
714739
1800
og lade meget få mennesker se dem.
11:56
The thing to do with data, if you want it to survive,
268
716539
2419
Det man skal gøre med data, hvis man vil have det til at overleve,
11:58
is to let it out and have everybody have it
269
718958
3301
er at slippe det fri og lade alle få det
12:02
with as little control on that data as possible.
270
722259
3099
med så lidt kontrol af dataene som muligt.
12:05
And that's what he did.
271
725358
1164
Og det er, hvad han gjorde.
12:06
And institutions can learn from this.
272
726522
3428
Og institutioner kan lære af dette.
12:09
Because institutions at the moment
273
729950
2552
For i øjeblikket indskrænker institutioner
12:12
confine their data with copyright restrictions and that sort of thing.
274
732502
3057
deres data med ophavsretsrestriktioner og den slags.
12:15
And if you want to look at medieval manuscripts on the Web,
275
735559
2192
Hvis man vil se på manuskripter fra middelalderen på nettet,
12:17
at the moment you have to go to the National Library of Y's site
276
737751
3471
er man nødt til at gå til Nationalbiblioteket Y's hjemmeside
12:21
or the University Library of X's site,
277
741222
2668
eller Universitetsbiblioteket X's hjemmeside,
12:23
which is about the most boring way
278
743890
1899
som er den mest kedelige måde,
12:25
in which you can deal with digital data.
279
745789
1777
man kan behandle digitale data på.
12:27
What you want to do is to aggregate it all together.
280
747566
2993
Det man skal gøre er, at samle det hele.
12:30
Because the Web of the ancient manuscripts of the future
281
750559
3097
Fordi fremtidens net af oldtidens manuskripter
12:33
isn't going to be built by institutions.
282
753656
2286
vil ikke blive bygget af institutioner.
12:35
It's going to be built by users,
283
755942
3108
Det vil blive bygget af brugere,
12:39
by people who get this data together,
284
759050
1774
af folk som samler disse data,
12:40
by people who want to aggregate all sorts of maps
285
760824
3535
af folk som vil samle alle mulige slags kort
12:44
from wherever they come from,
286
764359
1632
fra det sted de kommer fra,
12:45
all sorts of medieval romances
287
765991
1800
alle mulige slags romaner fra middelalderen
12:47
from wherever they come from,
288
767791
1549
fra det sted de kommer fra,
12:49
people who just want to curate their own glorious selection
289
769340
3783
folk som blot vil lave deres egen pragtfulde samling
12:53
of beautiful things.
290
773123
1517
af smukke ting.
12:54
And that is the future of the Web.
291
774640
1617
Det er nettets fremtid.
12:56
And it's an attractive and beautiful future,
292
776257
3183
Det er en tiltrækkende og smuk fremtid,
12:59
if only we can make it happen.
293
779440
1602
hvis vi blot kan bringe den til udfoldelse.
13:01
Now we at the Walters Art Museum have followed this example,
294
781042
3181
Vi, på Walters Art Museum, har fulgt dette eksempel,
13:04
and we have put up all our manuscripts on the Web
295
784223
3350
og vi har lagt alle vore manuskripter ud på nettet,
13:07
for people to enjoy --
296
787573
1683
så folk kan nyde dem --
13:09
all the raw data, all the descriptions, all the metadata.
297
789256
2584
al råmaterialet, alle beskrivelserne, alle metadata --
13:11
under a Creative Commons license.
298
791840
2883
under en Creative Commons licens.
13:14
Now the Walters Art Museum is a small museum
299
794723
1518
Walters Art Museum er et lille museum,
13:16
and it has beautiful manuscripts,
300
796241
1548
og det har smukke manuskripter,
13:17
but the data is fantastic.
301
797789
2018
men dataene er fantastiske.
13:19
And the result of this
302
799807
1783
Resultatet af dette er,
13:21
is that if you do a Google search on images right now
303

at hvis du søger på googles billede-søgning nu
13:24
and you type in "Illuminated manuscript Koran" for example,
304
804608
3332
og for eksempel skriver "Illuminated manuscript Koran",
13:27
24 of the 28 images you'll find come from my institution.
305
807940

vil 24, ud af de 28 billeder du finder, være fra min institution.

Now, let's think about this for a minute.
307
817907
5033
Lad os tænke over dette.
13:42
What's in it for the institution?
308
822940
1983
Hvad får institutionen ud af det?
13:44
There are all sorts of things that are in it for the institution.
309
824923
2596
Institutionen får en masse ud af det.
13:47
You can talk about the Humanities and that sort of thing,
310
827519
2123
Man kan nævne humaniora og den slags,
13:49
but let's talk about selfish things.
311
829642
1881
men lad os tale om egennyttige emner.
13:51
Because what's really in it for the institution is this:
312
831523
3868
Fordi det, som institutionen i virkeligheden får ud af det, er dette:
13:55
Now why do people go to the Louvre?
313
835391
3056
Hvorfor besøger folk Louvre?
13:58
They go to see the Mona Lisa.
314
838447
2984
For at se Mona Lisa.
14:01
Why do they go to see the Mona Lisa?
315
841431
3059
Hvorfor vil de se Mona Lisa?
14:04
Because they already know what she looks like.
316
844490
2382
Fordi de allerede ved, hvordan hun ser ud.
14:06
And they know what she looks like
317
846872
2334
Og de ved, hvordan hun ser ud
14:09
because they've seen pictures of her absolutely everywhere.
318
849206
4702
fordi de har set billeder af hende alle vegne.
14:13
Now, there is no need
319
853908
4449
Der er slet ikke brug
14:18
for these restrictions at all.
320
858357
2279
for disse begrænsninger.
14:20
And I think that institutions should stand up
321
860636
2087
Jeg synes, at institutioner burde
14:22
and release all their data under unrestricted licenses,
322
862723
3134
frigive alle deres data under ubegrænsede licenser,
14:25
and it would be a great benefit to everybody.
323
865857
2216
og det ville være til alles fordel.
14:28
Why don't we just let everybody have access to this data
324
868073
3166
Hvorfor lader vi ikke bare alle have adgang til disse data
14:31
and curate their own collection
325
871239
2336
og lave deres egen samling
14:33
of ancient knowledge and wonderful and beautiful things
326
873575
2165
af oldtidens viden og vidunderlige og smukke ting
14:35
and increase the beauty and the cultural significance
327
875740
3088
og derved øge skønheden og den kulturelle betydning
14:38
of the Internet.
328
878828
1228
af internettet?
14:40
Thank you very much indeed.
329
880056

Mange tak.
