1. The birth of the percussion method
In the 18th century, when an Austrian doctor was treating a patient, the patient died suddenly before the diagnosis was confirmed. After an autopsy, it was found that there was suppuration and pus accumulation in his chest. Can pus build up in the chest be diagnosed before dissection? How much have you accumulated? One day, in a hotel, he saw the guys moving wine barrels. He saw them knocking on this barrel and knocking on that barrel, listening with their ears while knocking. He suddenly realized that people judge how much wine is left in the barrel based on the sound made by tapping the barrel. So, can the amount of pus in the human chest also be judged by tapping? He boldly experimented and succeeded. In this way, a new diagnostic method - "percussion method" was born.
2. One hole is worth ten thousand gold
A sugar company in the United States suffered huge losses every time it shipped sugar cubes to South America because the sugar cubes got damp. As a result, someone thought that since the sugar cubes were sealed with wax and would get damp, it was better to poke a small hole with a small needle to ventilate it. After experiments, unexpected results were achieved, and he applied for a patent. According to media reports, the patent transfer fee is as high as US$1 million.
A Mr. K in Japan heard that poking small holes can be considered an invention, so he poked a needle here and there and immersed himself in research, hoping to come up with an invention. As a result, he discovered that by drilling a small hole in the flame core cover of the lighter, the lighter could be filled with oil from the original 10 days to 50 days. The invention was finally "poked" by him.
Old Man Baishi in the Wuyi style of painting
Qi Baishi was originally a carpenter. He became a painter through self-taught work and won the World Peace Prize. However, in the face of the success he has achieved, he is never satisfied. Instead, he constantly draws on the strengths of famous painters of all ages and changes the style of his works. His paintings after the age of 60 are obviously different from those before the age of 60. After the age of 70, his painting style changed again. After the age of 80, the style of his paintings changed again. It is said that Qi Baishi painted in the Wuyi style throughout his life; precisely because Baishi continued to work hard after his success, his works in his later years were more mature than his earlier works, forming a unique genre and style.
