Einstein said it.
Einstein, the greatest physicist in the 2th century, once said, "Interest is the best teacher." His life is the best interpretation of this sentence.
As a child, Einstein was inarticulate, withdrawn, and didn't like to associate with people. Teachers all thought that he would "accomplish nothing in whatever he did". However, since he was a child, he was full of strong thirst for knowledge and a wide range of interests.
when Einstein was five years old, his father gave him a compass. He was very surprised to find that the compass always pointed in a fixed direction, so he couldn't put it down, studied it every day and tried to find out the reason. He remembered this compass until he was old, and he felt that it was this little gadget that introduced him into a magical scientific world.
Einstein was born in 1879 in a Jewish family in Ulm, Germany (both parents were Jewish). He graduated from the Federal Institute of Technology in Zurich in 19 and became a Swiss citizen. In 195, Einstein received his Ph.D. in physics from the University of Zurich, put forward the photon hypothesis and successfully explained the photoelectric effect, so he won the 1921 Nobel Prize in physics.
Under the guidance of Max, Einstein began to study advanced mathematics. When Einstein was 13 years old, he was already studying calculus before his classmates of the same age could figure out congruent triangles's problem. Before long, even Max was no match for him. Max began to lend him books on physics and philosophy, such as Kant's Critique of Pure Reason, which was popular at that time. Einstein was able to understand it when he was 13 years old. In this way, young Einstein developed a hobby of mathematics, physics and philosophy.
As we all know, Einstein became a civil servant in the Swiss Federal Patent Office after graduating from college. However, because of his strong interest in physics, he insisted on continuing his research after work, thus putting forward a revolutionary and famous theory-relativity, and became a world-renowned master of physics. It is precisely because Einstein cultivated his personal interest from an early age and ignited his enthusiasm for life that he achieved such great achievements.
