English composition about the pros and cons of inventing explosives

, is a great Swedish chemist, known as the "King of Explosives". He was born in Stockholm, the capital of Sweden. His father loved science and wanted to use his wisdom to create something that did not exist in the world. One year, a fire broke out in Nobel's house, leaving the family impoverished and had to cross the ocean to make a living in Russia. My father opened a daily hardware store and also set up a small laboratory filled with machinery and various chemicals. He engaged in scientific experiments in addition to business.

Little Nobel often saw workers smashing rocks with pickaxes in the barren mountains in order to dig railways, which was laborious and time-consuming. My father invented an explosive that split the mountain apart effortlessly. He was fascinated by this magical explosive and liked to spend time in the laboratory with his father. He memorized the names of various chemicals and often asked his father questions he didn't understand. His father always patiently explained them to him and guided him in doing small experiments.

When Nobel was 17 years old, his father decided to let him travel around the world to broaden his horizons. He excitedly asked his father: "What is my mission for this trip?" His father said seriously: "You left home alone and traveled across the ocean to learn new science and technology from various countries. Do you understand?" Nobel nodded. .

Following his father's wishes, Nobel went to Germany, Italy and France, then went to England to participate in the World's Fair, and finally crossed the Atlantic and worked as an apprentice in a machinery factory in the United States.

Nobel’s trip took two years. In addition to enjoying the exotic scenery around the world, he also learned many new science and technology and some scientific experiments, and visited famous scientists, professors and scholars, which greatly broadened his horizons and increased his knowledge.

Nobel returned to his motherland and inherited his father's business of developing explosives. Once he was doing an experiment in the laboratory, and suddenly the explosive exploded. He was almost killed, and the laboratory was also destroyed. But he was not discouraged. He conducted hundreds of experiments and finally succeeded. The patent for explosives allowed him to accumulate a lot of wealth. Before his death, he left a will: to donate all his property, establish academic scholarships, and encourage the world All those who devote themselves to science.
