Black powder is one of the four great inventions in ancient China, commonly known as gunpowder. After the invention of black powder, the Arabs introduced this technology to Europe and it was used until the 19th century. During its use, people discovered that black powder had a fatal weakness: it was not very powerful and was not easy to detonate.
In order to meet the needs of the rapidly developing industry, scientists began to look for a new explosive power, and the Swedish scientist Alfred Bernard Nou who made outstanding contributions in this field was undoubtedly Bell. Nobel was born in October 1833 in Stockholm, the capital of Sweden. Nobel's family was poor when he was young, but influenced by his father who was an inventor, he was keen on inventions and creations. Nobel has been diligent and studious since he was a child. Although he only received one year of formal school education, he is proficient in English, French, German, Russian, Swedish and other languages, and his self-learning ability is evident. Not only in foreign languages, but also in the field of invention, little Nobel was more energetic in learning. He could observe his father's experiments for several hours.
When Nobel was 9 years old, his father took him to Russia and hired a tutor to teach him basic knowledge of mathematics, physics, and chemistry, and prepare him for future inventions. The foundation was laid. While studying, Nobel helped in the factory run by his father, which further enhanced his hands-on ability and provided him with knowledge and experience in production and management.
Nobel was a Swedish chemist. After his death, part of his property was donated to the bank, and the interest generated every year was used as bonuses to award the Chemistry Prize, the Physics Prize, the Physiology or Medicine Prize, the Literature Prize, and the Peace Prize. Later, the Swedish Bank added the Economics Prize, which issued bonuses, certificates, and medals. The number of winners of each award could not exceed three people.
Nobel faced these blows and constant criticism, but he did not lose heart. . He thought of the innocent people who were killed in the bombing and his poor brother Zhimir, and secretly made up his mind to develop a very safe nitroglycerin explosive. After countless experiments, he finally developed a solid state nitroglycerin explosive triggered by a detonator. In October 1866, the Kluber District of Germany organized a nitroglycerin dynamite review committee to conduct a certain safety review on the safety and power of the dynamite produced by Nobel. After review, all committee members agreed that this is a successful product that can be used and transported with absolute confidence.
Years of hard work have finally come to fruition. At the beginning of the next year, people from the German mining industry came to order a large amount of nitroglycerin explosive. Because the efficiency of mining has improved and no accidents have occurred, the miners are all happy. Then France and the United Kingdom also came to purchase, and even Nobel's home country Sweden also placed an order. Seeing that Sweden was willing to adopt it, Nobel said happily: "I can finally do something for my motherland." Once regarded as a terrible and dangerous item, it has now become a great contributor to blessing mankind.
The uses of nitroglycerin dynamite are so wide that it is difficult to describe them all. They are all needed for tunnel projects, railway development, canal digging, mountain excavation, road paving and bridge building, etc. Nitroglycerin explosive has promoted the rapid progress of science and technology in the world. Nobel's Kluber gunpowder factory continued to expand. By 1874, the supply of nitroglycerine explosive reached 3,120 tons.
