deep work

There were many types of deep-sea submarines, and different types worked differently. The working principle of a manned submarine was as follows: When diving, it was achieved by injecting seawater into the air cabin. For example, the Dragon had a ballasting iron in the early stage, so that it had negative buoyancy and sank into the sea. After the seabed operation was completed, the method of floating up was to abandon heavy objects such as the ballasting iron (such as the battery box, the sample basket, etc.). If it was entangled by seaweed, it could also abandon the mechanical arm to ensure safety. In the submarine controlled by the electromagnets, if the power was lost and the electromagnets failed, the ballasting iron would automatically separate under the effect of gravity to float up the submarine. There was also an alarm system that could send a float to the surface to seek rescue from the mother ship. The working principles of autonomous underwater robots and tethered underwater robots were not mentioned in the existing information. Some of the submarines had multiple cabins inside, such as a living cabin, a control cabin, and a drainage system cabin. When pumping water into the submarine, its internal structure could ensure that the people inside would not be flooded. For example, the Endeavor submarine used a cable-less and unpowered floating and diving technology that could operate continuously on the seabed for six hours. There were also ways to control the buoyancy through special devices, such as putting a small glass bottle filled with half water into a large bottle. When the bottle was squeezed, the water would enter the small bottle and compress the air, causing the drainage volume to decrease. The gravity would be greater than the buoyancy, and when the bottle was released, the air volume would expand, and the buoyancy would be greater than the gravity. However, this was not a common working principle of deep-sea submarines. It was only an example of a similar principle. The novel "Flood Dragon" is equally exciting.

It was not a novel," The Glass Era " was not Deep Blue's work. " The Glass Era " was a story about a cursed time-travel event. Deep Blue was a well-known online author who had created many excellent works such as the Dark Souls series and Original Gods.

There were many famous works in the world that were easy to act out, but there were relatively few famous works with profound meaning. The following are some of the world's famous works that I think are very valuable. They not only have extremely high literary value, but also profoundly reveal the nature and history of mankind: 1 A Short History of Mankind-Yuval Harari " A brief history of mankind " was a best-selling world famous book. It introduced the history of human beings from the emergence to the modern era in an easy-to-understand way, covering the evolution of human beings, the development of civilization, the progress of science and technology, and so on. This book not only revealed the brilliant light of human history, but also deeply explored the nature of mankind and the direction of the future. 1984-George Orwell 1984 was another profound masterpiece. It described the details of a dictatorial state and depicted the horror of the government controlling people's lives. This book profoundly reveals the nature of power and its impact on human society, warning us to be vigilant of the dangers of power. 3 Capital-Karl Karl Max Capital was one of the classic works of Marxists. This book revealed the nature and operating mechanism of capitalist society. This book deeply explored the development of the economy and society, revealing the nature of exploitation of the capitalist system, and it has an important role in guiding our understanding of the operation of society and the economy. 100 Years of Solitude by Garcia Marquez " One Hundred Years of Solitude " was a classic of Latino literature. It told the story of a seven-generation family, depicting the rise and fall of a family. This book profoundly reveals the nature of human history and the relationship between families, nations, and countries. It is a work of philosophical significance. Dream of the Red Chamber-Cao Xueqin Dream of the Red Chamber was a classic work of Chinese classical literature. This book described the love story of Jia Baoyu, Lin Daiyu and others, reflecting the various ills of feudal society. This book profoundly revealed the complexity of human nature and the decline of feudal society. It was a masterpiece with historical, philosophical, literary and other meanings.

Fifty Meters Deep was Liu Tong's first work.

I recommend you to read the novel "Intrusive Moon". It's also a novel about the infinite universe. The protagonist can freely go to other worlds to train. The new book,"My Revolution in the Mysterious World" was also written by this author, and the plot was rather bizarre. I hope you like my recommendation. Muah ~
