whereas art on the other hand
28

2089
๋ฐ˜๋ฉด์— ์˜ˆ์ˆ ์€
01:52
is usually an emotional approach to its surroundings.

30
116810
2017
์ œ๊ฐ€ ํ•˜๊ณ ์ž ํ•˜๋Š” ๋ฐ”๋Š”
01:58
to bring those two views into one
31

2641
์ด๋“ค ๋‘ ๊ฐ€์ง€ ๊ด€์ ์„ ํ•˜๋‚˜๋กœ ํ•ฉ์ณ์„œ
02:01
so that my images both speak to the viewer's heart
32

์ œ๊ฐ€ ์ฐ์€ ์‚ฌ์ง„์ด ๋ณด๋Š” ์‚ฌ๋žŒ๋“ค์˜ ๊ฐ์„ฑ๊ณผ ์ด์„ฑ์—

33

3194
๋ชจ๋‘ ํ˜ธ์†Œํ•˜๊ฒŒ๋” ํ•˜๋Š” ๊ฑฐ์ฃ .
02:08
Let me demonstrate this based on three projects.
34
128612
4666
์„ธ ๊ฐ€์ง€ ํ”„๋กœ์ ํŠธ์˜ ์˜ˆ๋ฅผ ๋ณด์—ฌ๋“œ๋ฆฌ๊ฒ ์Šต๋‹ˆ๋‹ค.
02:13
The first one has to do with making sound visible.
35
133278
5054
์ฒซ ์ž‘ํ’ˆ์€ ์†Œ๋ฆฌ๋ฅผ ๋ˆˆ์— ๋ณด์ด๊ฒŒ ํ•˜๋Š” ๊ฒƒ๊ณผ ๊ด€๋ จ์ด ์žˆ์Šต๋‹ˆ๋‹ค.
02:18
Now as you may know,
36
138332
1018
์—ฌ๋Ÿฌ๋ถ„๋„ ์•„์‹œ๋‹ค์‹œํ”ผ
02:19
sound travels in waves,
37
139350
2626
์†Œ๋ฆฌ๋Š” ํŒŒ๋™์œผ๋กœ ์ด๋™ํ•ฉ๋‹ˆ๋‹ค.
02:21
so if you have a speaker,
38
141976
2323
๊ทธ๋ž˜์„œ ์Šคํ”ผ์ปค๊ฐ€ ์žˆ์œผ๋ฉด
02:24
a speaker actually does nothing else
39

์Šคํ”ผ์ปค๋Š” ์‹ค์ œ๋กœ ๋ณ„๋‹ค๋ฅธ ์ผ์„ ํ•˜๋Š”๊ฒŒ ์•„๋‹ˆ๋ผ
02:26
than taking the audio signal,
40
146348
1884
์†Œ๋ฆฌ ์‹ ํ˜ธ๋ฅผ ๋ฐ›์•„์„œ
02:28
transform it into a vibration,
41
148232
3597
์ง„๋™์œผ๋กœ ๋ฐ”๊พธ๊ณ ,
02:31
which is then transported through the air,
42
151829
2701
์ง„๋™์ด ๊ณต๊ธฐ๋ฅผ ํ†ตํ•ด ์ด๋™ํ•˜๋ฉด
02:34
is captured by our ear,
43
154530
1862
์šฐ๋ฆฌ ๊ท€๊ฐ€ ๊ทธ๊ฒƒ์„ ํฌ์ฐฉํ•˜์—ฌ
02:36
and transformed into an audio signal again.
44
156392
3541
์†Œ๋ฆฌ ์‹ ํ˜ธ๋กœ ๋‹ค์‹œ ๋ฐ”๊พธ๋Š” ๊ฑฐ์ฃ .
02:39
Now I was thinking,
45
159933
1846
๊ทธ๋ž˜์„œ ์ €๋Š” ์ƒ๊ฐํ–ˆ์Šต๋‹ˆ๋‹ค.
02:41
how can I make those sound waves visible?
46
161779
4220
์–ด๋–ป๊ฒŒ ํ•˜๋ฉด ์ŒํŒŒ๋ฅผ ๋ˆˆ์— ๋ณด์ด๊ฒŒ ํ•  ์ˆ˜ ์žˆ์„๊นŒ?
02:45
So I came up with the following setup.
47
165999
2116
๊ทธ๋ž˜์„œ ๋‹ค์Œ๊ณผ ๊ฐ™์€ ์žฅ์น˜๋ฅผ ์ƒ๊ฐํ•ด๋ƒˆ์Šต๋‹ˆ๋‹ค.
02:48
I took a speaker, I placed a thin foil
48
168115
3720
์Šคํ”ผ์ปค๋ฅผ ๊ฐ€์ ธ๋‹ค๊ฐ€
02:51
of plastic on top of that speaker,
49
171835
2235
๊ทธ ์œ„๋ฅผ ์–‡์€ ํ”Œ๋ผ์Šคํ‹ฑ ๋ง‰์œผ๋กœ ๋ฎ์€ ๋‹ค์Œ
02:54
and then I added tiny little crystals
50
174070
2667
์•„์ฃผ ์ž‘์€ ์ˆ˜์ • ์•Œ๊ฐฑ์ด๋“ค์„
02:56
on top of that speaker.
51
176737
1977
๊ทธ ์œ„์— ์˜ฌ๋ ค๋†“์•˜์Šต๋‹ˆ๋‹ค.
02:58
And now, if I would play a sound through that speaker,
52
178714
2900
๊ทธ๋ฆฌ๊ณ  ๊ทธ ์Šคํ”ผ์ปค๋กœ ์†Œ๋ฆฌ๋ฅผ ํ‹€๋ฉด
03:01
it would cause the crystals to move up and down.
53
181614

์ˆ˜์ • ์•Œ๊ฐฑ์ด๊ฐ€ ์œ„ ์•„๋ž˜๋กœ ์›€์ง์ด๊ฒŒ ๋ฉ๋‹ˆ๋‹ค.
03:05
Now this happens very fast,

๊ทธ๋Ÿฐ๋ฐ ์ด ๊ณผ์ •์€ ์•„์ฃผ ๋นจ๋ฆฌ ์ผ์–ด๋‚˜์„œ

just on any of the beaches,

70
266223
1709
๋ฌด์Šจ ์ผ์ด ๋ฒŒ์–ด์กŒ๋ƒ ํ•˜๋ฉด
04:27
if you're shooting at 3,000 frames per second,

์ดˆ๋‹น 3์ฒœ ์žฅ๋ฉด์˜ ์‚ฌ์ง„์„ ์ฐ์œผ๋ ค๊ณ  ํ•˜๋ฉด

๊ทธ๋ž˜์„œ ์šฐ๋ฆฌ๋Š” ์Šคํ”ผ์ปค๋ฅผ ์„ค์น˜ํ•˜๊ณ

1355
์ €๋Š” ์Šคํ”ผ์ปค๋ฅผ ์„ค์น˜ํ•˜๊ณ

that I had a completely red face

Now I've got a live demonstration over here

So I've got a camera pointing down at this plate,

์ง€๊ธˆ ์—ฌ๋Ÿฌ๋ถ„์ด ๋ณด์‹œ๋Š” ๊ฒƒ์€

06:34
This is due to the attraction and the repulsion

2243
์ด๊ฑด ๊ฝค๋‚˜ ํฅ๋ฏธ๋กœ์šด๋ฐ
06:43

117

ํšจ๊ณผ๋Š” ๊ฐ™์Šต๋‹ˆ๋‹ค.
07:10
So what happened now is,
118
430798
2112
์ด์ œ ๋ณด์‹œ๋Š” ๊ฒƒ์€
07:12
when the watercolor was flowing into the structure,

07:19
That's because the ferrofluid itself

is hydrophobic.
122

That means it doesn't mix with the water.

Now, whiskey contains 40 percent of alcohol,

150
