2015.04.04月全食 2015.04.04 Total Lunar Eclipse

科學圖說 Scientific introduction

2015年4月4日月全食過程，18:15初虧，19:54食既，20:00食甚，20:06生光，21:45復圓，臺灣全程可見。月全食發生的時機正逢滿月，月球進入地球的本影區，而使亮面被遮掩造成虧食。在全食階段，因太陽光透過地球大氣層的折射與散射，可見進入地球本影區的月亮呈現暗紅色。整個過程十分精彩，以肉眼即可窺見天地之奧秘，為容易觀察的天象之一。本作品分別以廣角鏡頭和長鏡頭記錄月全食的連續變化，以及月球通過地球的本影。

A total lunar eclipse occurred on April 4, 2015. First contact was at 6:15 pm; second contact at 7:54 pm; third contact at 8:00 pm; greatest eclipse at 8:06 pm and fourth contact at 9:45 pm. This lunar eclipse could be viewed all around Taiwan. A total lunar eclipse only occurs when a full moon enters the earth’s umbra (shadow). During the total eclipse phase, due to the refraction and scattering of the sunlight through the earth’s atmosphere, the moon appears red. The entire process is spectacular. It is one of the astronomical phenomena that is relatively easy to see with the naked eye. These images of the successive changes during a total lunar eclipse were obtained with wide-angle and long focus lenses.

月上梢頭 Moon Above the Branches

科學圖說 Scientific introduction

朔的前後幾天，月球的暗部被地球反射的太陽光線隱隱照亮，形成「新月抱舊月」的天文現象，又名「灰光」。灰光是一種常見的天文現象，但前景的選擇尤為重要。清華大學天文臺始建於1931年，原名氣象臺，為中國大陸重點文物的保護單位。將天文臺和「灰光」這種天文現象拍攝在一起，顯得更有意義。

The first few days after a new moon, the dark part of the moon is faintly illuminated by sunlight reflected from the earth to create the astronomical phenomenon known as “old moon in the new moon’s arms”. It is also referred to as “ashen light”. Ashen light is a common astronomical phenomenon. The Tsinghua University observatory was constructed in 1931. It was an important cultural artifact preservation unit in China. Photographing this observatory together with ashen light makes this image more meaningful.

灕江第一灣銀河拱橋 Milky Way Arc Above Lijiang First Bend

科學圖說 Scientific introduction

在城市燈光的包圍中，仰望銀河的璀璨繁星，逐漸成為都市人的奢求。灕江流域的桂林山水不僅有世界上最獨特而優美的喀斯特峰林景觀，也有著獨特別緻的夜空。當銀河狀如拱橋在「灕江第一灣」的上空慢慢升起，美景輝映襯著銀河，共同營造出了優美壯麗且難得的人間景色。

As the cities are enveloped in artificial lighting, gazing at the array of stars in the Milky Way has become a leisure pursuit. Guilin in the Lijiang Basin is not only famous for its karst peak landscapes, but also for its picturesque night views. As the band of the Milky Way, in the shape of an arc, slowly rises over Lijiang First Bend, the beautiful landscapes are illuminated, creating a majestic scene that is difficult to see anywhere else in the world.

鬼斧神工 Natural Craftsmanship

科學圖說 Scientific introduction

位於地底深處的岩層，漸漸地暴露到地表時，由於壓力減小，岩石產生了裂痕，因此岩石和空氣與水的接觸面積增加，會沿著岩石的節理進行風化作用。若水中或岩石內含有鐵的成分，在長期風化作用下，鐵質會氧化生成氧化鐵，顏色也轉為褐色或咖啡色。氧化作用越完全，風化紋的顏色也越深。加上受海水長期淘洗而剝落，地層擠壓出縱橫交錯的裂縫，便生成彷彿鬼斧神工般的奇岩異石。

When rock strata that were once deep underground are gradually exposed, the pressure decreases creating fissures. This increases the contact area of the rocks with air and water along the joint, leading to erosion. If the water or rocks contain iron, over a long period of weathering the iron oxidizes to become ferric oxide. This leads to a change in color to brown. The more complete the oxidation, the deeper are the colors of the patterns. Due to the long term effects of sea water, a network of fissures has formed along the surface creating an intricate work of natural craftsmanship.

億萬年的仰望 Looking Upon Billions of Years

科學圖說 Scientific introduction

庫車大峽谷位於新疆天山南麓的庫車縣附近，南北走向，全長5公里，最寬處53公尺，最窄處僅0.4公尺，只容1人躬身通過。億萬年的地質作用和風雨侵蝕，造就了庫車大峽谷獨特的地貌景觀。紅褐色的岩石在正午光線的照射下，顯露出獨特的魅力和神秘的氛圍。在峰迴路轉的深處，人類在自然面前顯得無比渺小，那整齊的刀刻痕跡，是大自然留下的永恆力量。

Kuqa Gorge is located near the southern foothills of Tian Shan in Kuqa County, Xinjiang. It runs north to south for five kilometers, and has a maximum width of 53 meters. At its narrowest point it is only 0.4 meters. Billions of years of geological process and erosion by wind and rain have created the unique landscapes. The gorge is at its most beautiful when the sun shines on the reddish brown rocks at high noon. Along the winding paths in the deepest part of the gorge it is easy to feel insignificant in the face of Nature. The neat cuts are evidence of the everlasting power of Nature.

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.
