Goodnow is 97 years old and is known as the father of lithium batteries all over the world. Dai, an associate professor at the School of Metallurgy of Northeastern University, said: "All the battery materials we use now were invented by him in the 1980s. Without Goodenough's key discovery, lithium batteries may explode at any time. " Now, Mr. Goodnow, who is 97 years old, is still full of energy and active in the first-line research field, studying the problem of insufficient battery power. It is such a white-haired old man whose legendary experience has given us a lot of educational enlightenment. Then why was he discouraged by his tutor? In fact, it was not that he was persuaded to quit, but that his mentor prevented him from realizing his dream at the age of 30, but he still had no choice but to give up.
John Good had a bad relationship with his parents since he was a child. When he 12 years old, he went to boarding school with the help of a scholarship. Subsequently, John F. Goodnow entered Yale University with honors. In fact, he also missed his major and got lost. It's just, fortunately, he's going in the right direction.
During World War II, 25-year-old Goodnow was sent to serve in the United States Air Force. He was sent to an island in the Pacific Ocean to collect meteorological data and do meteorological work. This seems to have nothing to do with the research on chemical lithium batteries that he is good at. After the war, he returned to America. What is he doing? He thought about it and decided to continue studying!
So at the age of 30, he applied for a doctorate from the University of Chicago. This time he decided to choose a new major: physics! When he entered the school, the registrar dissuaded him and sarcastically said, "I really don't understand you veterans." Don't you know that people who have made great achievements in physics have already made achievements at your age? Do you want to start now? "
But he insisted on his own ideas and wanted to achieve something in physics. Finally, he got a doctorate in physics. What will the reading club bring? Many children may not understand the meaning of reading, and even in the eyes of many people, they think that reading has no practical function, and reading has not earned money from businessmen.
Although reading can't see the effect at present, it is the cornerstone of world progress. Anyone who has made outstanding contributions to the world, who invented steam engines, airplanes and trains, electric lights and movies, and mobile phones, did not study and do research! Most of them are university professors or laboratory researchers. What they have to do is to change the world with knowledge and technology. Reading is actually not personal wealth. People who can read are actually social wealth.
