Born in a Jewish family in Ulm, Germany, Einstein was particularly interested in various natural phenomena since he was a child. He is often fascinated by the shape of leaves, petal tissue, ants running, stars flashing and so on. When he was five, his father bought him a compass. He turns a small needle or a plate. No matter how he turns, Xiao Zhen doesn't listen to him and points south. Einstein was surprised. Although his father and uncle's answers seemed incomprehensible to him, this small magnetic needle always strongly attracted his curiosity. Einstein stepped into the hall of human science by relying on his strong thirst for knowledge and indomitable spirit of diligence and learning. The spirit of research and the habit of independent thinking in his youth eventually turned him into a generation of scientific superstars.
Einstein was good at revealing the essence of things with the insight of thinking, and innovated the old concepts of classical physics with the spirit of thorough innovation. 1905, at the age of 26, he created a miracle without precedent in the history of science. During this year, he used his spare time to publish three papers that shocked the world and made epoch-making contributions in three fields of physics. First of all, his paper on photoelectric effect established the optical quantum theory, successfully explained the photoelectric effect, and revealed the fluctuation of microscopic particles and the unity of particle properties for the first time in history, thus opening the door to quantum mechanics. Einstein won the Nobel Prize in Physics on 192 1. His paper on the change of time and space with the state of motion broke through the old idea that time and space are absolutely unchanged since Newton's time, revealed the essential unity of time and space as a form of material existence, announced the birth of special relativity and marked the arrival of a new scientific era. His law of mass-energy relationship about the equivalence of mass and energy reveals the secret of huge nuclear energy in atoms and shows a broad prospect for the peaceful use of nuclear energy by mankind. After eight years of hard work, he founded the general theory of relativity, which promoted the vigorous development of cosmology. Relativity and quantum mechanics have become the two pillars of modern physics, and Einstein's name has spread all over the world.
Einstein studied cosmology, unified field theory, physical philosophy and many other aspects in his life, and his thoughts still guide the direction of frontier disciplines. Einstein was also a soldier who maintained world peace and supported the just cause of mankind. During the two world wars, he protested against German militarism and Hitler's fascist tyranny. After the Second World War, he repeatedly called for opposing the expansion of the army and the use of nuclear weapons in the war. As a scientist with a strong sense of social responsibility, Einstein is revered by people all over the world.
Some people praised Einstein as a genius, and he said modestly, "I am not a genius." Then he euphemistically told the secret of his success: X+Y+Z = A, χ stands for hard work, Y stands for the correct method, Z stands for less empty talk, and A stands for success.
