So the questionvprašanje is, what is invisibleneviden?
0
0
5000
Vprašanje je torej, kaj je nevidno?
00:17
There is more of it than you think, actuallydejansko.
1
5000
3000
Pravzaprav več, kot si mislite.
00:20
Everything, I would say. Everything that matterszadeve
2
8000
3000
Rekel bi, da vse. Vse stvari, ki so pomembne,
00:23
exceptrazen everyvsak thing and exceptrazen matterzadevo.
3
11000
6000
razen vseh stvari in razen snovi same.
00:29
We can see matterzadevo. But we can't see what's the matterzadevo.
4
17000
4000
Stvari lahko vidimo. Ne moremo pa videti, v čem je stvar.
00:33
As in this crypticGrobni sentencestavek I foundnajdemo in The GuardianVaruh recentlypred kratkim:
5
21000
5000
Tako kot pri tem kodiranem sporočilu, ki sem ga pred kratkim našel v Guardianu:
00:38
"The marriagezakon sufferedtrpel a setbacknazadovanje in 1965,
6
26000
3000
"Njun zakon je zašel v težave leta 1965,
00:41
when the husbandmož was killedubil by the wifežena."
7
29000
3000
ko je žena ubila moža."
00:44
(LaughterSmeh)
8
32000
3000
(smeh)
00:47
There's a worldsvet of invisibilitynevidnost there, isn't there?
9
35000
2000
V tem je cel kup nevidnega, mar ne?
00:49
(LaughterSmeh)
10
37000
2000
(smeh)
00:51
So, we can see the starszvezde and the planetsplanetov,
11
39000
2000
Torej, lahko vidimo zvezde in planete,
00:53
but we can't see what holdsdrži them apartRazen
12
41000
3000
ne vidimo pa, kaj jih drži narazen
00:56
or what drawsčrpa them togetherskupaj.
13
44000
2000
ali kaj jih vleče skupaj.
00:58
With matterzadevo, as with people, we see only the skinkoža of things.
14
46000
3000
Pri snovi, tako kot pri ljudeh, lahko vidimo samo ovojnico.
01:01
We can't see into the enginemotor roomsoba.
15
49000
2000
Ne vidimo strojnice.
01:03
We can't see what makesnaredi people tickkljukico, at leastvsaj not withoutbrez difficultytežave.
16
51000
3000
Ne moremo videti, kaj poganja ljudi, vsaj ne brez težav.
01:06
And the closerbližje we look at anything, the more it disappearsizgine.
17
54000
4000
In bolj od blizu ko gledamo, bolj stvari izginjajo.
01:10
In factdejstvo, if you look really closelytesno at stuffstvari,
18
58000
2000
Pravzaprav, če pogledate res od blizu,
01:12
if you look at the basicosnovno substructurepodkonstrukcijo of matterzadevo,
19
60000
2000
če hočete videti temeljno strukturo snovi,
01:14
there isn't anything there.
20
62000
2000
tam ni nič.
01:16
ElectronsElektroni disappearizginejo in a kindvrste of fuzzFuzz,
21
64000
2000
Elektroni izginejo v nekakšni megli,
01:18
and there is only energyenergija. And you can't see energyenergija.
22
66000
5000
ostane samo energija. Te pa ne morete videti.
01:23
So everything that matterszadeve, that's importantpomembno, is invisibleneviden.
23
71000
3000
Vse, kar je torej pomembno, je nevidno.
01:26
One slightlymalce sillyneumno thing that's invisibleneviden
24
74000
3000
Ena od malo smešnih nevidnih stvari
01:29
is this storyzgodba, whichki is invisibleneviden to you.
25
77000
2000
je tale zgodba, ki je ne morete videti.
01:31
And I'm now going to make it visiblevidno to you in your mindsmisli.
26

3000
Zdaj bom naredil tako, da jo boste lahko videli v mislih.
01:34
It's about an M.P. calledpozval GeoffreyGeoffrey DickensDickens.
27
82000
4000
Gre za preminulega poslanca Geoffreya Dickensa.
01:38
The latepozen GeoffreyGeoffrey DickensDickens, M.P. was attendingprisotnost a feteSvečani in his constituencyvolilna enota.
28
86000
3000
Dickens je sodeloval na zabavi v svojem volilnem okraju.
01:41
WhereverKjerkoli he wentšla, at everyvsak stallstojnico he stoppedustavil he was closelytesno followedsledi
29
89000
3000
Kamorkoli je šel, pri katerikoli stojnici se je ustavil, mu je tesno sledila
01:44
by a devotednamenjen smilingnasmejan womanženska of indescribablenepopisno uglinessgrdega.
30
92000
3000
zvesta smehljajoča se ženska, ki je bila nepopisno grda.
01:47
(LaughterSmeh)
31
95000
2000
(smeh)
01:49
Try as he mightmorda, he couldn'tni mogel get away from her.
32
97000
2000
Nikakor ji ni mogel ubežati.
01:51
A fewmalo daysdnevi laterpozneje he receivedprejeto a letterpismo from a constituentsestavina
33
99000
2000
Čez nekaj dni je od volivke prejel pismo,
01:53
sayinggovoriti how much she admiredobčudoval him,
34
101000
2000
v katerem je napisala, kako ga občuduje,
01:55
had metsrečal him at a feteSvečani and askingsprašujem for a signedpodpisano photographfotografija.
35
103000
3000
da ga je srečala na zabavi in da ga prosi za podpisano fotografijo
01:58
After her nameime, writtennapisano in bracketsoklepaji was the aptapt descriptionopis, horsekonj faceobraz.
36
106000
5000
V oklepaju poleg njenega imena je bil jasen opis: konjski obraz.
02:03
(LaughterSmeh)
37
111000
1000
(smeh)
02:04
"I've misjudgednapačno presodila this womenženske," thought MrG.. DickensDickens.
38
112000
2000
"To žensko sem narobe ocenil," si je mislil Dickens.
02:06
"Not only is she awarese zaveda of her physicalfizično repulsivenessrepulsiveness,
39
114000
3000
"Ne samo da se zaveda svoje fizične odvratnosti,
02:09
she turnszavrti it to her advantageprednost.
40
117000
2000
spremeni jo celo v svojo prednost.
02:11
A photofotografija is not enoughdovolj."
41
119000
2000
Fotografija ni dovolj."
02:13
So he wentšla out and boughtkupil a plasticplastika frameokvir to put the photographfotografija in.
42
121000
3000
Šel je in kupil plastičen okvir, v katerega je vstavil fotografijo.
02:16
And on the photographfotografija, he wrotenapisal with a flourishrazcvetati,
43
124000
2000
Nanjo je vzneseno zapisal:
02:18
"To HorseKonj FaceObraz, with love from GeoffreyGeoffrey DickensDickens, M.P."
44
126000
5000
"Za konjski obraz, z ljubeznijo, poslanec Geoffrey Dickens"
02:23
After it had been sentposlano off, his secretarysekretar said to him,
45
131000
2000
Potem ko so fotografijo poslali, ga je tajnik vprašal,
02:25
"Did you get that letterpismo from the womanženska at the feteSvečani?
46
133000
2000
"Ste dobili pismo tiste ženske z zabave?
02:27
I wrotenapisal HorseKonj FaceObraz on her, so you'dTi bi rememberZapomni si who she was."
47
135000
4000
Nanj sem napisal 'konjski obraz', da bi se spomnili, kdo je bila."
02:31
(LaughterSmeh)
48
139000
6000
(smeh)
02:37
I betStavite he thought he wishedŽelel he was invisibleneviden, don't you?
49
145000
2000
Stavit grem, da si je takrat želel biti neviden, kaj pravite?
02:39
(LaughterSmeh)
50
147000
2000
(smeh)
02:41
So, one of the interestingzanimivo things about invisibilitynevidnost
51
149000
2000
Torej, ena od zanimivih stvari o nevidnosti
02:43
is that things that we can't see
52
151000
2000
je, da stvari, ki jih ne vidimo,
02:45
we alsotudi can't understandrazumeti.
53
153000
2000
tudi ne moremo razumeti.
02:47
GravityTeža is one thing that we can't see
54
155000
2000
Težnost je ena takih nevidnih
02:49
and whichki we don't understandrazumeti.
55
157000
2000
in nerazumljivih stvari.
02:51
It's the leastvsaj understoodrazumel of all the fourštiri fundamentaltemeljno forcessile,
56
159000
2000
Od štirih temeljnih sil je najmanj razumljena
02:53
and the weakestnajšibkejši.
57
161000
2000
in najšibkejša.
02:55
And nobodynihče really knowsve what it is or why it's there.
58
163000
2000
Nihče pravzaprav ne ve, kaj je in zakaj obstaja.
02:57
For what it's worthvredno, SirGospod IsaacIsaac NewtonNewton, the greatestnajvečji scientistznanstvenik who ever livedživel,
59
165000
3000
Še celo Isaac Newton, največji znanstvenik vseh časov,
03:00
he thought JesusJezus cameprišel to EarthZemlja specificallyposebej to operatedelovati the leversročice of gravitygravitacije.
60
168000
5000
je mislil, da je Jezus prišel na svet zato, da bi upravljal zakone težnosti.
03:05
That's what he thought he was there for.
61
173000
2000
To, je menil, je bila njegova vloga.
03:07
So, brightsvetlo guy, could be wrongnarobe on that one, I don't know.
62
175000
3000
Pameten možak, ampak pri temle se je morda zmotil, kaj pa vem.
03:10

65
182000

Pojma nimam, o čem razmišljate. Ni to noro?
03:17
Isn't that incredibleneverjetno that we can't readpreberite eachvsak other'sdrugi mindsmisli?
66
185000
3000
Ali ni neverjetno, da ne moremo brati misli drug drugega?
03:20
But we can touchdotaknite se eachvsak other, tasteokus eachvsak other perhapsmorda, if we get closeblizu enoughdovolj.
67

Lahko se dotikamo, celo okušamo, če smo si dovolj blizu.
03:24
But we can't readpreberite eachvsak other'sdrugi mindsmisli. I find that quitečisto astonishingpresenetljivo.
68
192000
3000
A ne moremo brati misli. To se mi zdi kar šokantno.
03:27
In the SufiSufi faithvera, this great MiddleSrednji EasternVzhodni religionreligija,

whichki some claimzahtevek is the routepot of all religionsreligije,

za katero nekateri trdijo, da je vodilo vseh religij,
03:33
SufiSufi mastersmojstri are all telepathstelepaths, so they say.
71
201000
5000
so vsi sufiji telepati, tako pravijo.

But theirnjihovi mainglavni exercisevadba of telepathytelepatija

03:45
So that's why we don't think it existsobstaja,

2000
Zato mislimo, da ne obstaja,

04:35
AnotherDrugo thing we can't see is the humančlovek genomegenom.
92
263000
3000
Še ena stvar, ki je ne moremo videti, je človeški genom.
04:38
And this is increasinglyvse bolj peculiarznačilen,
93
266000
3000
To je vse bolj čudna zadeva:
04:41
because about 20 yearslet agonazaj, when they startedzačel delvingdelving into the genomegenom,
94
269000
5000
pred 20 leti, ko so genom začeli raziskovati,
04:46
they thought it would probablyverjetno containvsebujejo around 100,000 genesgeni.
95
274000
3000
so mislili, da bo verjetno vseboval okoli 100,000 genov.
04:49
GeneticistsGenetiki will know this, but everyvsak yearleto sinceod,
96
277000
2000
Genetiki to že vedo, ampak odtlej so številko vsako leto
04:51
it's been revisedspremenjen downwardsnavzdol.
97
279000
2000
popravili navzdol.
04:53
We now think there are likelyverjetno to be only just over 20,000
98
281000
3000
Zdaj menimo, da je v človeškem genomu verjetno
04:56
genesgeni in the humančlovek genomegenom.
99
284000
2000
le nekaj nad 20,000 genov.
04:58
This is extraordinaryizredno. Because riceriž -- get this --
100
286000
3000
To je nenavadno. Kajti riž - poslušajte tole -
05:01
riceriž is knownznano to have 38 thousandtisoč genesgeni.
101
289000
4000
riž ima 38,000 genov.
05:05
PotatoesKrompir, potatoeskrompir have 48 chromosomeskromosomi. Do you know that?
102
293000
5000
Krompir ima 48 kromosomov. Ste to vedeli?
05:10
Two more than people,
103

Dva več kot človek
05:12
and the sameenako as a gorillagorila.

05:14
(LaughterSmeh)

05:16
You can't see these things, but they are very strangečudno.
106

3000
Teh stvari ne morete videti, so pa zelo čudne.
05:19
(LaughterSmeh)
107

05:21
The starszvezde by day. I always think that's fascinatingfascinantno.

111

Nihče ne vidi časa.
05:31
I don't know if you know this. ModernSodobne physicsfizika,
112
319000
2000
Ne vem, ali ste vedeli. V moderni fiziki
05:33
there is a bigvelik movementpremikanje in modernmoderno physicsfizika
113
321000
2000
obstaja veliko gibanje,
05:35
to decideodloči that time doesn't really existobstajajo,
114
323000
2000
ki zahteva odločitev, da čas v resnici ne obstaja,
05:37
because it's too inconvenientneprijetno for the figuresštevilke.
115
325000
3000
ker se ne sklada s številkami.
05:40
It's much easierlažje if it's not really there.
116
328000
2000
Veliko lažje je, če ga v resnici ni.
05:42
You can't see the futureprihodnost, obviouslyočitno.
117
330000
2000
Očitno je, da ne morete videti prihodnosti.
05:44
And you can't see the pastpreteklost, exceptrazen in your memoryspomin.
118
332000
3000
Preteklosti tudi ne, razen v spominu.
05:47
One of the interestingzanimivo things about the pastpreteklost is
119
335000
2000
Ena od zanimivosti preteklosti je,
05:49
you particularlyzlasti can't see. My sonsin askedvprašal me this the other day,
120
337000
3000
da je vi sami še posebej ne vidite. Zadnjič me je sin vprašal:
05:52
he said, "DadOče, can you rememberZapomni si what I was like when I was two?"
121
340000
2000
"Oči, se spomniš, kakšen sem bil, ko sem imel dve leti?"
05:54
And I said, "Yes." And he said, "Why can't I?"
122

Radijski valovi. To je še ena stvar.
08:19
HeinrichHeinrich HertzHertz, when he discoveredodkriti radioradio wavesvalovi in 1887,
179
487000
3000
Heinrich Hertz, ki jih je leta 1887 odkril,
08:22
he calledpozval them radioradio wavesvalovi because they radiatedsevajoče.
180
490000
2000
jih je imenoval radijski valovi, ker so oddajali energijo.
08:24
And somebodynekdo said to him,
181
492000
3000
In nekdo ga je vprašal:
08:27
"Well what's the pointtočka of these, HeinrichHeinrich?
182
495000
2000
"Hja, v čem je njihov smisel, Heinrich?
08:29
What's the pointtočka of these radioradio wavesvalovi that you've foundnajdemo?"
183
497000
3000
V čem je smisel radijskih valov, ki si jih našel?"
08:32
And he said, "Well, I've no ideaideja.
184
500000
2000
Hertz je odgovoril: "No, pojma nimam.
08:34
But I guessugibati somebodynekdo will find a use for them somedaynekega dne."
185
502000
3000
A menda bo nekdo nekoč ugotovil, da so za kaj uporabni."
08:37
And that's what they do, radioradio. That's what they discoveredodkriti.
186
505000
4000
In to počnejo, oddajajo, radio. To so iznašli.
08:41

187

Kakorkoli že, največja stvari,
08:44
that's invisibleneviden to us is what we don't know.
188

08:46

08:55
And I've come to the conclusionzaključek --
193
523000
3000
To nas pripelje do zaključka...
08:58
because you've askedvprašal this other questionvprašanje, "What's anotherdrugo thing you can't see?"
194
526000
3000
ker ste vprašali: "Česa še ne moremo videti?"
09:01

But the pointtočka, what I've got it down to,
200
542000
3000
Ampak smisel, kolikor razumem,
09:17
is there are only two questionsvprašanja really worthvredno askingsprašujem.
201
545000
2000
je v tem, da je res vredno postaviti samo dve vprašanji.
09:19
"Why are we here?" and "What should we do about it while we are?
202
547000
5000
"Zakaj smo tu?" in "Kaj naj s tem napravimo, dokler smo tu?"
09:24
And to help you, I've got two things to leavedopust you with, from two great philosophersfilozofi,

one a mathematicianmatematik and an engineerinženir, and the other a poetpesnik.
205

enega matematika in inženirja in enega pesnika.
09:35
The first is LudwigLudwig WittgensteinWittgenstein who said,
206

Prvi je Ludwig Wittgenstein, ki je dejal:
09:39
"I don't know why we are here.
207

2000
"Ne vem, čemu smo tu.
09:41
But I'm prettylepa sure it's not in orderred to enjoyuživajte ourselvessami."
