Wanda Diaz Merced proučava svjetlost koju emitiraju erupcije gama-zračenja, najenergetskiji događaji u svemiru. Kada je izgubila vid, a time i mogućnost bavljenja znanošću, došla je do neočekivanog otkrića: krivulje svjetlosti koje više nije mogla vidjeti moguće je prevesti u zvuk. Putem sonifikacije ponovno je ovladala svojim područjem, i sada se zalaže za inkluzivniju znanstvenu zajednicu. "Znanost je za sve", kaže. "Mora biti dostupna svima jer smo svi po prirodi istraživači."

Once there was a star.

2266
Bila jednom jedna zvijezda.
00:16
Like everything else, she was born;
1
4082
2722
Kao i sve ostalo, rođena je;
00:18
grew to be around 30 times
the mass of our sun
the mass of our sun
2
6828
3781
narasla je oko 30 puta
većom od našeg Sunca
većom od našeg Sunca
00:22
and lived for a very long time.
3
10633
2293
i dugo je poživjela.
00:25
Exactly how long,
4
13475
1368
Koliko točno,
00:26
people cannot really tell.
5
14867
1739
ne možemo znati.
00:29
Just like everything in life,
6
17162
1779
Kao i sve u životu,
00:30
she reached the end
of her regular star days
of her regular star days
7
18965
3449
došla je do kraja
svojih zvjezdanih dana
svojih zvjezdanih dana
00:34
when her heart, the core of her life,
8
22438
2577
kada je njezino srce,
srž njezina života,
srž njezina života,
00:37
exhausted its fuel.
9
25039
1466
ostalo bez goriva.
00:38
But that was no end.
10
26905
1307
No to nije bio kraj.
00:40
She transformed into a supernova,
and in the process
and in the process
11
28236
3526
Transformirala se u supernovu,
00:43
releasing a tremendous amount of energy,
12
31786
2654
emitirajući pritom
ogromnu količinu energije,
ogromnu količinu energije,
00:46
outshining the rest of the galaxy
13
34464
2708
zasjenila je ostatak galaksije
00:49
and emitting, in one second,
14
37196
2334
u jednoj sekundi emitirajući
00:51
the same amount of energy
our sun will release in 10 days.
our sun will release in 10 days.
15
39554
4073
jednaku količinu energije
koliku sunce emitira u deset dana.
koliku sunce emitira u deset dana.
00:55
And she evolved
into another role in our galaxy.
into another role in our galaxy.
16
43651
3271
Preuzela je drugu ulogu u našoj galaksiji.
00:59
Supernova explosions are very extreme.
17
47783
2474
Eksplozije supernove vrlo su žestoke.
01:02
But the ones that emit gamma rays
are even more extreme.
are even more extreme.
18
50638
4220
No one koje emitiraju
gama zrake još su žešće.
gama zrake još su žešće.
01:07
In the process of becoming a supernova,
19
55417
2289
Dok postaje supernova,
01:09
the interior of the star collapses
under its own weight
under its own weight
20
57730
3423
unutrašnjost se zvijezde
uruši pod vlastitom težinom,
uruši pod vlastitom težinom,
01:13
and it starts rotating ever faster,
21
61177
2888
okrećući se sve brže,
01:16
like an ice skater when pulling
their arms in close to their body.
their arms in close to their body.
22
64089
3865
poput klizača koji privlači ruke k sebi.
01:20
In that way, it starts rotating very fast
and it increases, powerfully,
and it increases, powerfully,
23
68592
4458
Tako se brže rotira, jako povećavajući
01:25
its magnetic field.
24
73074
1560
svoje magnetsko polje.
01:27
The matter around the star
is dragged around,
is dragged around,
25
75011
3089
Materija oko zvijezde povlači se za njom
01:30
and some energy from that rotation
is transferred to that matter

26
78124
3318
i dio energije od rotacije
prenosi se na materiju
prenosi se na materiju
01:33
and the magnetic field
is increased even further.
is increased even further.
27
81466

te se magnetsko polje još povećava.
01:37
In that way, our star had extra energy
to outshine the rest of the galaxy
to outshine the rest of the galaxy
28
85477
5762
Tako zvijezda dobiva energiju
kojom može zasjeniti ostatak galaksije
kojom može zasjeniti ostatak galaksije
01:43
in brightness and gamma ray emission.

01:46
My star, the one in my story,
30
94119
2489
Moja zvijezda, ona iz moje priče,
01:48
became what is known as a magnetar.
31
96632
2648
naziva se magnetar.
01:51
And just for your information,
32
99304

Informacije radi,
01:53
the magnetic field of a magnetar
is 1,000 trillion times

The most energetic events
ever measured by astronomers

35
107953
2656
02:02
carry the name gamma-ray bursts
36
110633
2255
nazivaju se bljeskovi gama-zračenja
02:04
because we observe them
as bursts most or explosions,

37

3607
jer ih vidimo kao
bljeskove ili eksplozije,
bljeskove ili eksplozije,
02:08
most strongly measured as gamma-ray light.
38
116543
2533
a najsnažnije su kao gama-zračenje.
02:11
Our star, like the one in our story
that became a magnetar,

during the most energetic
portion of the explosion.

02:22
Yet, even though gamma-ray bursts
are the strongest events

42
130167

Iako su gama-bljeskovi
najsnažniji događaji

02:27
ever measured by astronomers,
43
135492
2089
ikada izmjereni
02:29
we cannot see them with our naked eye.
44
137605
2637
ne možemo ih vidjeti golim okom.
02:32
We depend, we rely on other methods

Oslanjamo se na druge metode

And beyond that, we rely on other methods.
50

2272
Za ostalo, oslanjamo se na druge metode.
02:48
Yet as astronomers,
we study a wider range of light

51
156442
5260
Mi astronomi, proučavamo
širi doseg svjetlosti

and we depend on other methods to do that.

i pri tome koristimo druge metode.

On the screen, it may look like this.

U ranoj fazi karijere
i ja sam mogla vidjeti ovakav graf.
i ja sam mogla vidjeti ovakav graf.
03:34
But then, I lost my sight.
63
202562
2728
No tada sam izgubila vid.
03:37
I completely lost my sight
because of extended illness,
because of extended illness,
64
205314
3152
Izgubila sam vid zbog duge bolesti,
03:40
and with it, I lost
the opportunity to see this plot

65
208490
3685
a s vidom sam izgubila
mogućnost da vidim ovaj graf

03:45
and the opportunity to do my physics.
66
213208
2757
i da se bavim fizikom.
Za mene je to bilo
teško prijelazno razdoblje.

03:49
It was a very strong transition
for me in many ways.

67
217672

03:53
And professionally, it left me
without a way to do my science.

68
221295
4245
Profesionalno, nisam se
više mogla baviti znanošću.

03:57
I longed to access and scrutinize
this energetic light

69
225564
4615
Silno sam željela
proučavati tu energetsku svjetlost

04:02
and figure out the astrophysical cause.
70
230203
2686
i dokučiti njezin astrofizički uzrok.
04:04
I wanted to experience

04:13
I thought long and hard about it,
73
241352
3300
Dugo sam o tome razmišljala,
04:16
when I suddenly realized
that all a light curve is,

74
244676
3685
kada sam shvatila
da je krivulja svjetlosti

04:24
So along with my collaborators,
76
252861

Zajedno sa suradnicima,
04:26
we worked really hard and we translated
the numbers into sound.

4208
marljivo sam radila
na prevođenju brojeva u zvuk.

04:31
I achieved access to the data,
78
259765
2004
Uspjela sam doći do podataka
04:33
and today I'm able to do physics
at the level of the best astronomer,

79
261793
5013
i danas se mogu baviti fizikom
na razini najboljeg astronoma,

04:38
using sound.
80
266830
1151
koristeći zvuk.
04:40
And what people have been able to do,
81
268005
2628
I sve što ljudi mogu,
04:42
mainly visually,
82
270657
1153
uglavnom koristeći vid,
04:43
for hundreds of years,
83
271834
1344
stotinama godina,
04:45
now I do it using sound.
84

04:56
brought something to the ear
beyond the obvious burst.

04:59
Now I'm going to play the burst for you.
91
287973

Sad ću vam pustiti zvučni zapis bljeska.
05:01
It's not music, it's sound.

05:18
So listening to this
brought something to the ear

97

2310
Slušanjem sam čula još nešto
05:21
besides the obvious burst.

Mislim da ste ga čuli, zar ne?
06:11
So what we found
112

1277
Dakle, otkrili smo
06:12
is that the bursts last long enough
in order to support wave resonances,

ABOUT THE SPEAKER
Wanda Diaz Merced - Sonic astrophysicistWhile searching for ways to study stellar radiation without relying on sight, Wanda Diaz Merced has developed a way to represent complex data about our universe as sound.
Why you should listen
When Wanda Diaz Merced lost her sight in her early 20s, her dreams of studying stars in the visually oriented scientific world suffered a major setback -- until she discovered “sonification,” a way to turn huge data sets into audible sound using pitch, duration and other properties. Merced realized that she could use her ears to detect patterns in stellar radio data, and could uncover connections obscured by graphs and visual representation.
While working at the Harvard-Smithsonian Center for Astrophysics, Merced’s sonifications inspired musician and researcher Gerhard Sonnert to create X-Ray Hydra, an album of oddly jazzy music based on her audio representations.
