水內聚力與螞蟻 Water Cohesion and the Ant

科學圖說 Scientific introduction

螞蟻是好奇的昆蟲，聞到什麼都會靠近觸碰看看！水的內聚力佳，在螞蟻的觸碰下也不會破裂。此為內聚力影像實驗紀錄，加上拍攝時燈光的適度照射，使水滴不只晶瑩剔透，更反射背景的紅花，讓畫面更加立體！

Ants are curious insects, daring to come in contact with whatever they sense. Water is highly cohesive. When the ant comes in contact with the water droplet it does not break. These images are experimental observations of cohesion. With the appropriate amount of illumination, the water droplet sparkles and appears translucent, as well as reflects the red flower in the background, creating a 3-D effect.

迪士尼回憶 Disney’s Memory

科學圖說 Scientific introduction

魔法大門，開啟虛實交錯的甬道，一對俏皮的圓耳，突然蹦出。白手套拉開慶典的序幕，跳舞的咖啡杯輕碰，有你。成群的泡泡輕觸，有你。旋轉木馬交織騎士的夢，摩天輪裡的容顏，有你。雲霄飛車上有我的青春飛逝。零食、服飾、文具、街角，都有你。以歡笑為土，悄然埋下種子，等待、發芽。啊！原來你在這列隊歡迎。

A magic door opens, revealing a pathway to a fantasy world. A pair of round ears suddenly appears and a pair of white gloved hands pulls back a curtain to a celebration. Coffee cups whirl. Clusters of bubbles lightly collide. A carousel is interwoven with a dream of knights on horseback. There are also the faces on a Ferris wheel and roller coasters that bring to mind fleeting youth. There are snacks, costumes, stationery, and street corners. Laugher is the soil and sadness buries the seeds. There is waiting. Then, germination. Oh! You are in this line to be welcomed.

短暫之美 Transient Beauty

科學圖說 Scientific introduction

時常在路上，看著面帶笑容的孩子，手上拿著泡泡水，吹出一顆顆的泡泡，泡泡隨著光線折射，讓我看見了短暫而美麗的色澤，我們稱之為「薄膜干涉」。一束光照射於薄膜上，由於折射率不同，光波會被薄膜的上介面與下介面分別反射，且相互干涉而形成新的光波。然而，泡泡水中的油跟水，會因為重力及微氣流的影響，而在薄膜上產生不同的變化，所以細看之下，每次呈現的色澤與紋路都是截然不同。

We can often see children standing outside with smiles on their faces, as they hold a bottle of bubble solution in their hands, blowing bubble after bubble. Due to light refraction, transient and beautiful colors are produced. We refer to this as “thin film interference”. When light shines on a thin film, due to differences in the refractive index, light waves are separately reflected on the film’s upper and lower surfaces. New light waves are produced from mutual interference. Due to gravity and micro air currents, the oil and water in the bubble solution cause thin film variations. If you look closely, you will see that different colors and hues are produced!

空間錯覺 Spatial Illusion

科學圖說 Scientific introduction

生活當中有許多讓人的眼睛產生錯覺的事物，空間錯覺經常可見。拍攝現場布置兩面鏡子，中間擺上一些物品，兩面鏡子互相反射，造成空間的錯覺，仔細抓好角度，就可以拍攝出深邃曲線隧道的錯覺。需留意自己和鏡頭不要入鏡。

There are many optical illusions in daily life, with spatial illusions common among them. There are two mirrors. Between them are various objects. This spatial illusion is caused by the reciprocal reflections of the two mirrors. By carefully selecting the angle, while keeping myself and the camera away from the mirrors, a curved tunnel appears.

潑水成冰 Splashing Water Over Ice

科學圖說 Scientific introduction

2016年農曆臘月初8，民俗中一年最冷的一天，本人用瓶子盛滿開水，在開闊的黑龍江冰面上，將水灑向天空。

The eighth day of the last month on the lunar calendar should be the coldest day of the year according to folk customs. On that day in 2016, I filled a bottle with water and splashed it over the vast icy surface of Heilongjiang.

多層皇冠 Multi-layered Crown

科學圖說 Scientific introduction

凝固高速運動液體的攝影方法，一般可達2萬分之1秒。液體由甘油、牛奶、酒精和普通水製成，並在液體中加入食用色素增色。由電磁閥控制的滴管，把液體滴落在一塊放有少量酒精的黑色壓克力板上，由於滴落的液體與酒精表面張力相差很大，落下的液體與壓克力板發生一系列碰撞後，產生了像多層皇冠一樣的奇妙景象。碰撞過程非常短暫，產生的各種奇妙瞬間，一般無法用肉眼觀察，是名符其實的轉眼即逝，彷彿進入如夢如幻的童話世界。

Liquid high-speed photography methods were used. With these methods, shutter speed can reach 1/20,000 seconds. Liquids included glycerin, milk, alcohol and water, with added food coloring. A pipette with solenoid valve allowed for the controlled release of liquid drops onto a black acrylic board to which a small amount of alcohol was applied. Due to the large differences in surface tension between the liquid and the alcohol, the liquid hitting the acrylic board resulted in a series of impact reactions, producing this intriguing image of a multi-layered crown. This process is so quick that it cannot be observed with the naked eye. Through this image we are transported into a fairytale world.

液體圓舞曲 Liquid Waltz

科學圖說 Scientific introduction

液體高速攝影，是利用閃光燈的最小輸出，在黑暗環境下凝固高速運動液體的一種攝影方法。快門可以達到2萬分之1秒。利用不同液體間的表面張力，以噴射、反彈、風吹等方法，表現不同表面張力的液滴，捕捉在碰撞時產生千姿百態的瞬間。液體由甘油、普通水、增稠劑製成，在液體加入食用色素增色。本圖反映液體碰撞的短暫過程，一般無法用肉眼觀察。

In liquid high-speed photography, the flash is set to the lowest output. Liquids are photographed in a dark environment with shutter speed reaching 1/20,000 second. These images are the result of differences in surface tension, as well as spray jet, repulsion and blowing of air. Mid-air collisions caused different effects. These images were produced with glycerin and water, as well as thickening agents and food coloring. The very short impact process shown here cannot be observed with the naked eye.
