Edison never pays attention to his appearance. His clothes are often wrinkled, and some of them are corroded by acid. His shoes are seldom oiled, his hands are often stained with chemicals, and his hair is sometimes messy.

When he got up on Christmas morning, Edison, who wanted to be the groom's official, packed himself up. His hair is shining, his clothes are "brand-new" and his shoes are polished. At this moment, a friend came in and saw Edison dressed differently in peacetime, pacing back and forth anxiously in the room, and asked him what was wrong. Edison replied, "I'm going to do something very important in this new dress today, but I forget what it is." A friend comforted him and said, "Don't worry, take your time." Edison paced back and forth for a few minutes, and then suddenly shouted happily, "Oh, I remember, I'm going to have a wedding today!" " "

At two o'clock in the afternoon, just after the wedding, Edison sneaked into his laboratory. It turns out that he is improving the telegraph these days, and he wants to study an automatic telegraph. Even on his wedding day, he couldn't help worrying about his telegram. Some guests wanted to talk to him, so they looked for him everywhere, but they didn't know where he had gone. I didn't find it until after ten o'clock in the evening. I had to send someone to look for it again, and finally found it in the laboratory on 12 in the afternoon-he was playing with his telegram there, and no one read it.

Why didn't Edison worry about his telegram on his wedding day? This is the result of his obsession with experiments. At the wedding, his attention was still on the telegram. He suddenly thought of a solution to the design of the automatic telegraph, fearing that he would forget it after a long time, he quietly told the bride that he was going to the laboratory. The bride thought he wouldn't stay long, so she agreed. I didn't expect him to walk for ten hours.

Edison received only three years of formal education. He became a great inventor because of his "99% sweat". There are more than 300 notebooks with 200 pages each. In order to develop practical incandescent lamps, more than 6000 kinds of metallic materials and 1600 kinds of nonmetallic materials were tried. After confirming that the carbonized bamboo filament can be used as the filament of this lamp, we sent people to collect more than 6,000 kinds of bamboo samples from all over the world and finally decided to use the bamboo produced in Hachiba, Japan as the filament. In order to try a new battery, he used more than 9,000 materials and failed more than 50,000 times ... These are the stories of his obsession with scientific research and invention.

His obsession with invention and the good use of collective wisdom earned him the reputation of the king of invention. Among his inventions that are difficult to count accurately, the practical incandescent lamp and its complete power supply system, mobile film machine and tape recorder are his "three great inventions".

1862, 15-year-old Edison did a good deed. At the critical moment when the train came, he saved a child, only to know later that it was the son of the stationmaster. To show his gratitude, the stationmaster taught him how to send and receive telegrams. From then on, he began to make good luck. This naturally reminds people of the famous saying of the British philosopher Francis Bacon: "There are many tiny and excellent qualities in a person, and these qualities may eventually become lucky opportunities."

Edison's first wife died unfortunately when he was young, so he got married twice and both wives gave him three children. Half of his success is also attributed to his well-educated second wife. Thomas Comford Martin, a famous editor and engineer, once disclosed in his book that Edison "had no other hobbies, never participated in any sports and entertainment activities, and even completely ignored the minimum hygiene requirements in life", which was due to his wife's "taking care of Edison as one of her life purposes". Otherwise, because of this careless lifestyle, he will have to die early for many years ... "

Edison was not the only groom who "disappeared" on the wedding day. Just 22 years before Edison got married, that is, at the end of May of 1849, a similar scene happened at the University of Strasbourg in France. The guests were waiting for the wedding of Pasteur and Mary, the daughter of the university president, but they didn't see Pasteur. A friend who knew him well finally found him in the laboratory. His friends blamed him and said, "The bride and friends are worried. Why don't you go? " Pasteur replied, "Are you crazy? My friend, do you want to stop my experiment halfway? No, I have to finish today's experiment before I can go to the wedding. " He didn't hold the wedding until the experiment of studying crystals got satisfactory results. Fortunately, Mary is familiar with the chemistry professor who fell in love at first sight and didn't blame him. Pasteur, the 29-year-old groom, said happily to her, "I love you like my chemical crystal!" " "

It is with constant devotion and persistence that scientists have achieved success after success and created miracles after miracles.
