  • An image is worth more than a thousand words,

    圖片能傳達的訊息,勝過千言萬語

  • so I'm going to start my talk

    因此我的演講

  • by stop talking and show you a few images

    將以緘默和幾張最近捕捉的影像作為開頭

  • that I recently captured.

    將以緘默和幾張最近捕捉的影像作為開頭

  • So by now, my talk is already 6,000 words long,

    截至目前為止我的演講已多達六千字

  • and I feel like I should stop here.

    因此我認為這次演講就到此為止

  • (Laughter)

    (笑聲)

  • At the same time, I probably owe you

    但我猜想我還虧欠你們

  • some explanation

    有關這些影像的一些說明

  • about the images that you just saw.

    身為一名攝影師、

  • What I am trying to do as a photographer,

    同時也是一位藝術家,我致力於

  • as an artist, is to bring the world

    將藝術和科學的世界結合在一起

  • of art and science together.

    無論是肥皂泡沫

  • Whether it is an image of a soap bubble

    在破裂瞬間所捕捉到的畫面

  • captured at the very moment where it's bursting,

    如同你們所見的這張

  • as you can see in this image,

    無論是油漆的微小粒子組成的世界

  • whether it's a universe made of tiny little beads

    無論是油漆的微小粒子組成的世界

  • of oil paint,

    以非常奇特方式呈現的特殊液體

  • strange liquids that behave in very peculiar ways,

    或者油漆因離心力所產生的圖案

  • or paint that is modeled by centrifugal forces,

    我不斷嘗試將這兩個領域做結合

  • I'm always trying to link those two fields together.

    我發現,兩者引人入勝之處

  • What I find very intriguing about those two

    在於一個共同點:

  • is that they both look at the same thing:

    都是對於周遭環境的回應

  • They are a response to their surroundings.

    但卻是以截然不同的方式

  • And yet, they do it in a very different way.

    單就科學而論

  • If you look at science on one hand,

    科學以一種十分理性的角度

  • science is a very rational approach

    回應周遭的環境

  • to its surroundings,

    而另一方面呢

  • whereas art on the other hand

    藝術則常以感性作為切入

  • is usually an emotional approach to its surroundings.

    我正在做的是

  • What I am trying to do is I'm trying

    試者把兩者的觀點合而為一

  • to bring those two views into one

    因此,我拍攝的影像不僅與觀眾感性對談

  • so that my images both speak to the viewer's heart

    也進行理性討論

  • but also to the viewer's brain.

    我將以三個實驗來向各位說明

  • Let me demonstrate this based on three projects.

    第一是聲音的形象化

  • The first one has to do with making sound visible.

    眾所皆知的是

  • Now as you may know,

    聲音以聲波形式傳遞

  • sound travels in waves,

    假設有一台揚聲器

  • so if you have a speaker,

    其實揚聲器只用來接收音頻訊號

  • a speaker actually does nothing else

    將其轉換為振頻

  • than taking the audio signal,

    並藉由空氣的傳播

  • transform it into a vibration,

    由我們的耳朵所感知

  • which is then transported through the air,

    然後再次轉換成音頻訊號

  • is captured by our ear,

    因此我不斷思索

  • and transformed into an audio signal again.

    如何將聲波形象化呢?

  • Now I was thinking,

    我想到以下的裝置

  • how can I make those sound waves visible?

    我找了一個揚聲器

  • So I came up with the following setup.

    在上面鋪上一層塑膠薄片

  • I took a speaker, I placed a thin foil

    並放了小小的水晶

  • of plastic on top of that speaker,

    在揚聲器上

  • and then I added tiny little crystals

    這樣一來,使用揚聲器播放聲音時

  • on top of that speaker.

    上面的水晶會上下跳動

  • And now, if I would play a sound through that speaker,

    這一切都在轉瞬間發生

  • it would cause the crystals to move up and down.

    以迅雷不及掩耳的速度進行

  • Now this happens very fast,

    我們藉助一部 LG 的攝影機

  • in the blink of an eye,

    以每秒捕捉三千張圖像以上的速度

  • so, together with LG, we captured this motion

    拍下了一切

  • with a camera that is able

    以下是我們所捕捉到的圖像

  • to capture more than 3,000 frames per second.

    (音樂:強烈衝擊合唱團的《淚珠》)

  • Let me show you what this looks like.

    (掌聲)

  • (Music: "Teardrop" by Massive Attack)

    非常感謝

  • (Applause)

    我也覺得那令人嘆為觀止

  • Thank you very much.

    但我要告訴你們一個有趣的事

  • I agree, it looks pretty amazing.

    在洛杉磯拍攝時

  • But I have to tell you a funny story.

    我居然在室內曬傷了

  • I got an indoor sunburn doing this

    這個季節,到洛杉磯任一海灘

  • while shooting in Los Angeles.

    都可以曬出一身美麗的古銅色

  • Now in Los Angeles, you could get a decent sunburn

    但我卻是在室內

  • just on any of the beaches,

    而原因是

  • but I got mine indoors,

    若你想以每秒三千個畫面去拍攝

  • and what happened is that,

    所需光量將非常可觀、無比大量的光

  • if you're shooting at 3,000 frames per second,

    我們把揚聲器準備好

  • you need to have a silly amount of light, lots of lights.

    攝影機朝它拍攝

  • So we had this speaker set up,

    並投以大量的光線

  • and we had the camera facing it,

    一切準備就緒之後

  • and lots of lights pointing at the speaker,

    再將水晶珠子放在揚聲器上

  • and I would set up the speaker,

    不斷重複這樣的步驟

  • put the tiny little crystals on top of that speaker,

    直到中午我才發現

  • and we would do this over and over again,

    我的臉被揚聲器上投射的強光

  • and it was until midday that I realized

    曬得像關二哥一樣

  • that I had a completely red face

    有趣的是

  • because of the lights pointing at the speaker.

    揚聲器架設在我的右邊

  • What was so funny about it was that

    所以只有右半邊的臉被曬紅

  • the speaker was only coming from the right side,

    後來的幾天

  • so the right side of my face was completely red

    我看起來就像歌劇魅影裡的魅影

  • and I looked like the Phantom of the Opera

    我的第二個構想

  • for the rest of the week.

    涉及了一些低強度的有害物質

  • Let me now turn to another project

    在座有人聽過鐵磁流體嗎?

  • which involves less harmful substances.

    有人聽過,太棒了!

  • Has anyone of you heard of ferrofluid?

    我要省略那個部份嗎?

  • Ah, some of you have. Excellent.

    (笑聲)

  • Should I skip that part?

    鐵磁流體的特性非常奇妙

  • (Laughter)

    它是一種極黑的液體

  • Ferrofluid has a very strange behavior.

    濃稠度和油相似

  • It's a liquid that is completely black.

    含有微小的金屬微粒

  • It's got an oily consistency.

    金屬微粒使它具有磁性

  • And it's got tiny little particles of metal in it,

    若是將液體注入磁場中

  • which makes it magnetic.

    外觀就會改變

  • So if I now put this liquid into a magnetic field,

    我準備現場示範讓各位更加清楚

  • it would change its appearance.

    這台攝影機朝著下方薄板拍攝

  • Now I've got a live demonstration over here

    薄板下面,有一塊磁鐵

  • to show this to you.

    現在我要在磁鐵上方

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

    注入一些鐵磁流體

  • and underneath that plate, there is a magnet.

    然後稍微地向右移

  • Now I'm going to add some of that ferrofluid

    調整一下焦距,很好!

  • to that magnet.

    現在可以發現

  • Let's just slightly move it to the right

    鐵磁流體形成尖刺狀

  • and maybe focus it a little bit more. Excellent.

    成因是鐵磁流體內

  • So what you can see now is that

    金屬微粒相吸與相斥的作用

  • the ferrofluid has formed spikes.

    這已經相當有趣

  • This is due to the attraction and the repulsion

    我現在要加點水彩進去

  • of the individual particles inside the liquid.

    就只是一般的水彩

  • Now this looks already quite interesting,

    平常用來畫畫那種

  • but let me now add some watercolors to it.

    你可能不會用針筒來畫

  • Those are just standard watercolors

    但原理是一樣的

  • that you would paint with.

    你看到的是

  • You wouldn't paint with syringes,

    當水彩流進這個結構裡

  • but it works just the same.

    水彩不會和鐵磁流體相融合

  • So what happened now is,

    因為鐵磁流體本身具有疏水性

  • when the watercolor was flowing into the structure,

    也就是不和水融合

  • the watercolors do not mix with the ferrofluid.

    同時它也盡量在磁鐵上方

  • That's because the ferrofluid itself

    保持原來的位置

  • is hydrophobic.

    因而產生了

  • That means it doesn't mix with the water.

    令人驚豔的

  • And at the same time, it tries to maintain its position

    水彩運河和迷你池塘

  • above the magnet,

    這是我第二個構想

  • and therefore, it creates those amazing-looking

    而最後一個實驗

  • structures of channels and tiny little ponds

    會用到

  • of colorful water paint.

    蘇格蘭的國民飲料

  • So that was the second project.

    (笑聲)

  • Let me now turn to the last project,

    這個影像,還有這個

  • which involves

    都是威士忌的貢獻

  • the national beverage of Scotland.

    你心想︰

  • (Laughter)

    他怎麼辦到的?

  • This image, and also this one,

    他是乾掉半瓶的威士忌後

  • were made using whiskey.

    然後把酒醉的幻覺

  • Now you might ask yourself,

    畫在紙上嗎?

  • how did he do that?

    我保證在拍這些照片時

  • Did he drink half a bottle of whiskey

    是完全清醒的

  • and then draw the hallucination he got

    威士忌含有 40% 的酒精

  • from being drunk onto paper?

    而酒精有些非常有趣的特性

  • I can assure you I was fully conscious

    也許你曾經體驗過

  • while I was taking those pictures.

    其中一些特性

  • Now, whiskey contains 40 percent of alcohol,

    但我說的物理特性

  • and alcohol has got some very interesting properties.

    跟你們想的可不太一樣

  • Maybe you have experienced

    當我打開酒瓶後

  • some of those properties before,

    酒精分子會瀰漫在空氣中

  • but I am talking about the physical properties,

    因為酒精是易揮發的物質

  • not the other ones.

    同時也相當易燃

  • So when I open the bottle, the alcohol molecules

    歸功於這兩個特性

  • would spread in the air,

    我才有辦法創作出

  • and that's because alcohol is a very volatile substance.

    你們眼前所見的這些影像

  • And at the same time, alcohol is highly flammable.

    讓我做個現場示範

  • And it was with those two properties

    這是一個空的玻璃容器

  • that I was able to create the images

    裡面什麼都沒有

  • that you're seeing right now.

    我要在裡面填充氧氣

  • Let me demonstrate this over here.

    和威士忌

  • And what I have here is an empty glass vessel.

    再多加一點

  • It's got nothing in it.

    只要等個幾秒鐘

  • And now I'm going to fill it with oxygen

    讓分子散佈在瓶子內

  • and whiskey.

    然後一把火燒了它

  • Add some more.

    (笑聲)

  • Now we just wait for a few seconds

    就是這樣

  • for the molecules to spread inside the bottle.

    反應的速度真的很快,感覺沒什麼了不起的

  • And now, let's set that on fire.

    我可以重做一遍

  • (Laughter)

    有些人可能會抗議

  • So that's all that happens.

    這簡直就是浪費威士忌,我寧願把它喝掉

  • It goes really fast, and it's not that impressive.

    但請看看慢動作版

  • I could do it again to show it one more time,

    這是在沒有光線的暗房裡拍攝的

  • but some would argue that this is a complete waste

    如同我剛才在現場示範的一樣

  • of the whiskey, and that I should rather drink it.

    火焰

  • But let me show you a slow motion

    從玻璃瓶口到瓶底

  • in a completely darkened room

    燃燒了空氣分子和酒精的混和物

  • of what I just showed you in this live demonstration.

    燃燒了空氣分子和酒精的混和物

  • So what happened is that the flame

    所以你們一開始所看到的影像

  • traveled through the glass vessel from top to bottom,

    其實就是火焰在瓶子裡

  • burning the mix of the air molecules

    燃燒時定格的畫面

  • and the alcohol.

    試著想像

  • So the images that you saw at the beginning,

    將影像翻轉180度後

  • they are actually a flame stopped in time

    就是我所呈現出來的圖片

  • while it is traveling through the bottle,

    (掌聲)

  • and you have to imagine

    謝謝

  • it was flipped around 180 degrees.

    我展示了以上三個實驗

  • So that's how those images were made.

    你或許會納悶:這有什麼了不起的?

  • (Applause)

    你究竟想表達些什麼?

  • Thank you.

    學會怎麼浪費威士忌?

  • So, I have now showed you three projects,

    不過是些奇特的材質?

  • and you might ask yourself, what is it good for?

    以上三個實驗基於非常簡單的

  • What's the idea behind it?

    科學現象

  • Is it just a waste of whiskey?

    例如:磁力、聲波、

  • Is it just some strange materials?

    或是物質的物理特性

  • Those three projects, they're based on very simple

    而我希望呈現的

  • scientific phenomena,

    是利用這些科學現象

  • such as magnetism, the sound waves,

    並以具詩意的、前所未見的方式

  • or over here, the physical properties of a substance,

    藉此邀請觀賞者

  • and what I'm trying to do

    暫停片刻

  • is I'm trying to use these phenomena

    思索一下

  • and show them in a poetic and unseen way,

    這些生活週遭的美麗事物

  • and therefore invite the viewer

    非常感謝

  • to pause for a moment

    (掌聲)

  • and think about all the beauty

  • that is constantly surrounding us.

  • Thank you very much.

  • (Applause)
