Aurora in Narvik, Norway
Aurora is a large-scale discharge process around the earth. As part of the solar wind, charged particles rush to the earth at a speed of 3 million km/h. When they reach near the earth, they are captured by the earth's magnetic field, causing some of them to approach the north and south poles along the field line. When these charged particles enter the polar upper atmosphere, they collide with atoms and molecules in the atmosphere, which will produce 1 million trillion energy. Small particles in the earth's atmosphere will release energy; for instance, oxygen atoms emit green or red light, oxygen molecules emit red or yellow light, and nitrogen molecules emit purple or pink light. The aurora most often occurs in the two annular zones near the North-South magnetic latitude of 67 degrees, which are called the South Pole region and the North Aurora region respectively. This photo was taken in the winter of 2019, when I traveled to Narvik, Norway.
Xia pu tidal-flat area
If you stand by a lake and look down at the water beneath your feet, you will see that the water is transparent and not particularly reflective; If you look at the lake in the distance, you will see that the water is not transparent, but the reflection is very strong. This is called the Fresnel effect. This photo was taken in Xia pu tidal-flat area in Fujian Province, China. In the evening, after the low tide, fishermen are fishing for shellfish in the shallow water. The sunset shines on the water, reflecting the light and shadow, creating a unique scene of abundance
Caption: The Blooming of Dew
Introduction： In the morning scene shown in the photograph, the spider's web above a succulent plant is decorated with dewdrops like a veil of crystal, making the flowers even more delicate. Dewdrop formation is a liquefaction phenomenon. In the warm season, the air is relatively humid, and when the temperature drops gradually, the water vapor in the air cools and liquefies into small droplets that fall on plants and form transparent dewdrops which shine incredibly bright due to total internal reflection. At the same time, the nano-scale natural hydrophobic layer on the plant surface allows the landscape to be preserved. Short as the unique masterpiece of nature lasts, there’s no doubt that it is a thought-provoking experience to appreciate the breathtaking scenery along with the scientific theory lying underneath.
Description: This picture shows the star trails under the radio telescope. The star trails are the path of light produced by a star moving across the sky using a long exposure. The distance variation and azimuth variation of stars relative to the solar system can be ignored.The earth's rotation axis points to the position of Polaris, so it looks like all the stars will rotate from east to west around Polaris. The position of the stars does not move with respect to the stellar background. The image was taken between 12 and 1 a.m. at the Miyun Radio Astronomy Observatory.
An eye of the sky
I met this scene when I was travelling in Yunnan. It is called solar halo. It is an atmospheric optical phenomenon which appears when the sunshine through the volume layer cloud and reflects or refracts by the ice crystals. When the sunshine rip into the ice crystals in clouds, it will become different color lights go to different direction with the twice refraction. It usually comes in spring or summer. It is also a sigh which means wind and rain is coming soon. In some countries, there will be more than one hundred and thirty days with the solar halo in a year.
When I first saw this scene, I just thought it was like an eye of the sky. There are more than nine arc light In this picture and they interspersed with others which construct a partly hidden and partly visible scene. It was my first time to see a wonderful and fantastic natural scene which was so unforgettable. It let me know the beauty of nature and start to feel the nature. This is the reason that I took this photo.

Title: Twenty Seconds of Light pollution
Description: This photo recorded the light pollution in downtown Montreal at night for a short time with a shutter speed of twenty seconds. The content of the photo contains two parts: buildings, and lighting. For buildings, only blue-gray tones are retained. And the bright orange is used in the lighting part to form a sharp contrast with the blue-gray buildings, thus highlighting the light pollution of the city. Light pollution is excessive, misdirected, or inappropriate outdoor lighting. Too much light pollution washes out the view of the Universe, increasing energy consumption, interferes with astronomical research, disrupts ecosystems, and affects the health and safety of humans and wildlife. Light pollution can have as great an impact on the planet as levels of carbon monoxide and other airborne pollutants. The theme of this photo is to use the strong visual impact, which is brought by the contrast of bright orange tones of lighting and blue-grey tones of buildings in the photo, to warn people to pay more attention to light pollution and to call on people to reduce light pollution.
Title: Light Path
Description: This picture clearly shows the path of light reflected. Because the edges of the glass have been cut into multiple bevels, light coming in from the edges will be reflected at multiple angles. The transmittance of glass is limited, so there only part of the light can get through it. Therefore, we can see that light had been reflected back when it irradiated to the surface of the transparent glass. but at the same time, there are still some lights can go through it, so the brightness of the reflected light was reduced, and the light internal reflection in the glass makes it looks like had been light up.At the same time, the rough surface of the table diffuses the light, reflecting parallel incoming light in many different directions, so the reflection looks blurry.
Title: Foregathering With The Kingfisher
Description: Foregathering With The Kingfisher is a photo representing a beautiful Kingfisher picking up a small fish in its sharp beak. The photo shows the food chains between animals and how our mother Earth conducting our environemnt in a scientific manner.
The weight of the fish that a kingfisher eats every day accounts for about 60% of its body weight. They will squat for a long time in a place with a good view of the water (such as a sticking branch, a protruding lotus, or a protruding stone platform on the shore). Once they see the prey, they will rush out like an arrow from the string. Entering the water, grabbing the fish, exiting the water, and flying back to the resting place are almost completed in an instant. After entering the water, the kingfisher can maintain excellent vision, because his eyes can quickly adjust the viewing angle contrast caused by the light in the water after entering the water. Of course, even with such a quick fish catching action, the success rate is not 100%.
Yet the Kingfisher is a endangered animal speice, the photo could also be a really good publication to show people the beauty of Kingfisher and rise public's awareness towards the Kingfisher.
Title: Crystal Inlay
Description: From a distance, it seems to be a Mosaic of crystals, but closer, it is the common drops of water on the lotus leaf. The water does not spread out entirely on the leaf, keeping with nature’s “energy-saving” principle that it takes the least amount of energy to keep water in contact with lotus leaves. The rough surface structure of the lotus leaf can trap a large amount of air between the water and the lotus leaf, reducing the contact surface between the two, and the smaller the contact area, the more hydrophobic the leaves are. Moreover, The two material interfaces are so different that repel each other. Therefore the water drops that do not spread on the leaf under the sunlight provide us with an artful phenomenon like crystal inlaid on the lotus leaves.
Title: The Bee
Description: The external bees will collect the nectar from flowers and give it to the internal bees. The internal bees will suck in and spit out the collected nectar, repeatedly, and by constantly stirring their wings and dancing their bodies, to evaporate the excess water in the nectar, reducing the water content from about 60% to 20% or less, and forming a high concentration of honey liquid. This is the physical function of bees in making honey.
As nectar becomes dense, bees secrete digestive enzymes such as sucrase, amylase, and other invertases. These digestive enzymes convert the sucrose contained in the nectar into glucose and fructose. honey is the only naturally occurring simple sugar. At the same time, during the transformation process, more active substances will be added to provide more abundant nutrients for honey. This is the chemical process that bees use to make honey.
When the nectar has undergone both chemical and physical effects, the bees will put the nectar into the nest, and seal it with wax. It usually takes 7-15 days for the nectar to ferment before it becomes mature honey.
Title: Cosmic Bubble
Description: The bubble (film) slowly becomes thinner and thicker due to gravity, and Thin-film interference occurs between the light from the inside and the outside of the film. Part of the light superimposed on each other and brighter, part of each other to cancel and becomes darker, becomes colorful.
Description: The birds in the photo are called Garrulax albogularis. Here, a Garrulax Albogularis shares food, which I think is to save the female energy to lay eggs. The male has found food for her. These birds are usually in small groups of 5 to more than 10 individuals. They mainly live on the ground and forage under the forest or in the shrubs. The breeding period of Garrulax albogularis is from May to July. Nests are in the mountain forest, placed in the undergrowth of the bush or on the branches of the small tree. Their nest just like a cup, built by the grass stem, grass leaves, grass roots and other materials, the pad has a fine grass stem and fibrous roots. There are mostly 3 to 4 eggs in each brood. The eggs are dark blue and oval in shape. The size of these eggs is 29 mm ×21 mm. The Garrulax albogularis are small, only about 28cm long. They are brown on the top of their heads and sepia on their upper bodies. With conspicuous white hairs on their throats and tail feathers, they are swaggering and easy to spot in the wild. These Garrulax albogularis are mainly found in various forests and bamboo groves in the low mountains, hills and foothices at an altitude of about 1,000 meters. They mainly feed on insects and are known as "noisy tits" in Sichuan because of their unique calls.
