I'm a creative technologist
0
0
2000
Jeg er en kreativ teknolog
00:20
and the focus of my work is on public installations.
1
2000
5000
og fokuset i mit arbejde er offentlige installationer.
00:25
One of my driving passions
2
7000
3000
Og en af mine drivende passioner
00:28
is this idea of exploring nature,
3
10000
2000
er idéen om at udforske naturen
00:30
and trying to find hidden data within nature.
4
12000
2000
og prøve at finde skjult materiale i naturen.
00:32
It seems to me that there is
5
14000
3000
og for mig ser det ud, som om der er
00:35
this latent potential everywhere, all around us.
6
17000
2000
det her latente potentiale overalt, omkring os.
00:37
Everything gives out some kind of data,
7
19000
2000
Alt giver en eller anden form for oplysninger
00:39
whether it's sound or smell or vibration.
8
21000
3000
uanset om det er lyd eller lugt eller vibrationer.
00:42
Through my work, I've been
9
24000
2000
Og igennem mit arbejde har jeg
00:44
trying to find ways to harness and unveil this.
10
26000
4000
prøvet at finde måder at høste og frigøre dette på.
00:48
And so this basically led me to
11
30000
3000
Så, dette leder mig basalt til
00:51
a subject called cymatics.
12
33000
2000
et emne kaldet cymatik
00:53
Now, cymatics is the process of visualizing sound
13
35000
5000
Så, cymatik er processen hvor man visualiserer lyd
00:58
by basically vibrating a medium such as sand or water,
14
40000
4000
ved basalt at vibrere et emne, såsom sand eller vand,
01:02
as you can see there.
15
44000
2000
som I kan se her.
01:04
So, if we have a quick look at the history of cymatics
16
46000
3000
Hvis vi hurtigt kigger på cymatikkens historie
01:07
beginning with the observations of resonance,
17
49000
2000
med start i resonansobservationer
01:09
by Da Vinci, Galileo, the English scientist Robert Hook
18
51000
4000
af Da Vinci, Galileo, den engelske videnskabsmand Robert Hook,
01:13
and then Ernest Chladni.
19
55000
2000
og så Ernest Chladni.
01:15
He created an experiment using a metal plate,
20
57000
3000
Han startede et eksperiment ved at bruge en metalplade,
01:18
covering it with sand and then bowing it
21
60000
3000
dække den med sand, og så stryge den,
01:21
to create the Chladni patterns that you see here on the right.
22
63000
5000
for at skabe Chladnimønstret som I ser her til højre.
01:26
Moving on from this, the next person to explore this field
23
68000
3000
Videre fra det, til den næste der udforskede dette felt
01:29
was a gentleman called Hans Jenny in the 1970s.
24
71000
2000
som var en gentlemand ved navn Hans Jenny i 1970'erne
01:31
He actually coined the term cymatics.
25
73000
3000
og han skabte faktisk begrebet cymatik.
01:34
Then bringing us into the present day
26
76000
2000
Og videre til i dag
01:36
is a fellow collaborator of mine
27
78000
2000
er en af mine samarbejdspartnere
01:38
and cymatics expert, John Stewart Reed.
28
80000
3000
og cymatikekspert, John Stewart Reed.
01:41
He's kindly recreated for us
29
83000
2000
Han har været så venlig at genskabe
01:43
the Chladni experiment.
30
85000
2000
Chladnieksperimentet for os.
01:45
What we can see here is
31
87000
2000
Det vi kan se her, er
01:47
the metal sheet, this time connected to a sound driver
32
89000
3000
metal pladen, denne gang koblet til en lyddriver.
01:50
and being fed by a frequency generator.
33
92000
2000
der fodres af en frekvensgenerator.
01:52
As the frequencies increase,
34
94000
2000
Og som frekvensen stiger,
01:54
so do the complexities of the patterns that appear on the plate.
35
96000
3000
stiger ligeledes kompleksiteten af mønsteret der kommer frem på pladen.
01:57
As you can see with your own eyes.
36
99000
5000
Som I kan se med jeres egne øjne.
02:02
(Applause)
37
104000
4000
(Klapsalve)
02:06
So, what excites me about cymatics?
38
108000
3000
Nå, hvad begejstrer mig ved cymatik?
02:09
Well, for me cymatics is an almost magical tool.
39
111000
3000
Tja, for mig, er cymatik næsten et magisk værktøj.
02:12
It's like a looking glass into a hidden world.
40
114000
4000
Det er et syn ind i en anden verden.
02:16
Through the numerous ways that we can apply cymatics,
41
118000
3000
Og igennem de utallige veje vi kan bruge cymatik
02:19
we can actually start to unveil the substance of things not seen.
42
121000
5000
kan vi faktisk begynde at fremvise substansen af ting, der ikke kan ses.
02:24
Devices like the cymascope, which you can see here,
43
126000
2000
Maskiner så som cymaskopet, som I kan se her,
02:26
have been used to scientifically observe cymatic patterns.
44
128000
4000
har været brugt til videnskabelige observationer af cymatiske mønstre.
02:30
And the list of scientific applications is growing every day.
45
132000
3000
Og listen af videnskabelige ansøgninger vokser hver dag.
02:33
For example, in oceanography,
46
135000
3000
for eksempel i oceanografi,
02:36
a lexicon of dolphin language is actually being created
47
138000
3000
er et leksikon over delfinsprog faktisk ved at blive skabt
02:39
by basically visualizing the sonar beams that the dolphins emit.
48
141000
3000
ved rent faktisk at visualisere de lydstråler som delfiner udsender.
02:42
And hopefully in the future we'll be able to gain some deeper understanding
49
144000
3000
Og forhåbentlig vil vi i fremtiden være i stand til, at få en dybere forståelse
02:45
of how they communicate.
50
147000
2000
af hvordan de kommunikerer.
02:47
We can also use cymatics for healing and education.
51
149000
2000
Vi kan også bruge cymatik til helbredelse og undervisning.
02:49
This is an installation developed with school children,
52
151000
2000
Det her er en installation udviklet med skolebørn.
02:51
where their hands are tracked. It allows them
53
153000
2000
Hvor deres hænder bliver fulgt. Og det giver dem mulighed for
02:53
to control and position cymatic patterns
54
155000
2000
at kontrollere og placere cymatiske mønstre
02:55
and the reflections that are caused by them.
55
157000
3000
og spejlingerne skabt af dem.
02:58
We can also use cymatics as a beautiful natural art form.
56
160000
3000
Vi kan også bruge cymatik som en smuk naturlig kunstform.
03:01
This image here is created from a snippet
57
163000
3000
Det her billede er skabt af et øjeblik
03:04
of Beethoven's Ninth Symphony playing through a cymatic device.
58
166000
4000
af Beethovens niende symfoni, som spiller gennem en cymatisk maskine
03:08
So it kind of flips things on its head a little bit.
59
170000
3000
så det vender ligesom lidt om på tingene.
03:11
This is Pink Floyd's "Machine"
60
173000
2000
Og der her er Pink Floyd's "Machine"
03:13
playing in real time through the cymascope.
61
175000
3000
spillet i reel tid gennem cymaskopet.
03:21
We can also use cymatics as a looking glass into nature.
62
183000
3000
Vi kan også bruge cymatik som et vindue ind i naturen.
03:24
And we can actually recreate the archetypal forms of nature.
63
186000
3000
Og vi kan rent faktisk rekreere de arketypiske former i naturen.
03:27
So, for example, here on the left we can see a snowflake as it would appear in nature.
64
189000
4000
For eksempel, her til venstre er et snefnug, som det ville se ud i naturen.
03:31
Then on the right we can see a cymatically created snowflake.
65
193000
3000
Og til højre ser vi en cymatisk skabt snefnug.
03:34
And here is a starfish and a cymatic starfish.
66
196000
2000
Og her er en søstjerne og en cymatisk søstjerne.
03:36
And there is thousands of these.
67
198000
2000
Og der er tusinder af dem.
03:38
So what does this all mean?
68
200000
2000
Så hvad betyder alt det her?
03:40
Well, there is still a lot to explore
69
202000
3000
Altså, der er stadig meget at udforske.
03:43
in its early days. And there's not many people working in this field.
70
205000
2000
Og det er tidligt. Der er ikke mange der arbejde på det her område.
03:45
But consider for a moment that sound does have form.
71
207000
4000
Men overvej for et øjeblik, at lyd har en form.
03:49
We've seen that it can affect matter and cause form within matter.
72
211000
4000
Og at vi hat set at det kan påvirke ting, og skabe form i ting.
03:53
Then sort of take a leap and think about the universe forming.
73
215000
4000
Tag så et spring, og tænk på universets skabelse.
03:57
And think about the immense sound of the universe forming.
74
219000
3000
Og tænk på den enorme lyd af universet der bliver skabt.
04:00
And if we kind of ponder on that, then perhaps
75
222000
2000
Og hvis vi ligesom overvejer det
04:02
cymatics had an influence on the formation of the universe itself.
76
224000
5000
kan cymatik måske have haft en indflydelse på opstillingen af selve universet.
04:07
And here is some eye candy for you, from a range of
77
229000
2000
Og her er lidt fryd for øjet til jer, fra et udvalg af
04:09
DIY scientists and artists
78
231000
2000
gør-det-selv videnskabsfolk og kunstnere
04:11
from all over the globe.
79
233000
2000
fra hele verden.
04:13
Cymatics is accessible to everybody.
80
235000
2000
Og cymatik er tilgængeligt for alle.
04:15
I want to urge everybody here to
81
237000
2000
Og jeg vil gerne bede alle her om
04:17
apply your passion, your knowledge
82
239000
3000
at bruge jeres passion, jeres viden
04:20
and your skills to areas like cymatics.
83
242000
2000
og jeres evner til områder som cymatik.
04:22
I think collectively we can build a global community.
84
244000
3000
Og jeg tror at vi sammen kan skabe et globalt samfund.
04:25
We can inspire each other.
85
247000
2000
Vi kan inspirere hinanden.
04:27
And we can evolve this exploration
86
249000
2000
Og vi kan udvikle den udforskning
04:29
of the substance of things not seen. Thank you.
87
251000
2000
af substansen af ting vi ikke kan se. Tak
04:31
(Applause)
