Examples of knowing something from the smallest detail
1. Newton and Apple
Around 1666, Newton had already considered the problem of gravity when he lived in his hometown. During the holidays, he often sat for a while in the garden. Once, as happened many times in the past, an apple fell from the tree.
The accidental falling of an apple was a turning point in the history of human thought. It opened up the mind of Newton sitting in the garden and caused him to ponder: What is the reason why all objects are affected by similar effects? What about the attraction that is always toward the center of the earth? Newton thought. Finally, he discovered gravity, which was of epoch-making significance to mankind.
2. Archimedes took a bath
Once Hieron II made a gold crown, but he always suspected that the goldsmith had stolen his gold. Mixed with silver. So he invited Archimedes to appraise it, on the condition that the crown would not be damaged. At that time, people did not know that different substances had different specific gravity. Archimedes thought hard for many days, but there was no good way.
One day, he went to take a bath. As soon as he lay down in the tub filled with warm water, the water overflowed and he felt his body floating slightly. Then he suddenly thought that objects of the same weight would discharge different amounts of water due to different volumes. He stopped taking a shower, jumped out of the tub, and ran home naked down the street.
When his servant rushed home panting, Archimedes was already conducting experiments; he put the crown into a basin filled with water, measured the overflowing water, and added the same weight to The pure gold was put into a basin filled with water, but the water that overflowed was less than what had just spilled, so he concluded that the goldsmith had mixed silver into the crown. From this, he discovered the principle of buoyancy.
3. The Wright brothers invented the airplane
The Wright brothers’ father brought them a "butterfly" toy for Christmas. The father told them that it was a flying spiral that could fly high in the air. Fly to high ground. From then on, in their young minds, they had the idea that they would create something that could fly high into the sky in the future. This desire has always affected them.
The Wright brothers not only strived to master the research results of their predecessors, but also paid great attention to learning directly from living flying objects-birds. They often lie on their backs on the ground and carefully observe the flight of eagles in the sky for several hours, studying and thinking about their take-off, landing and hovering mechanisms.
The miracle happened on December 17, 1903. Early that morning, Kitty Hawk in North Carolina, USA, was still sleeping. The weather was cold and windy. A strange guy with huge wings was parked quietly on the empty beach. This was the first person in human history. An airplane - "Aviator One".
4. Watt's improved steam engine
When Watt was a child, he went to his aunt's house and saw the boiling water making the kettle lid keep jumping. This inspired him to find inspiration, but he was often stopped by his grandmother. After repeated trials, he finally invented an improved steam engine when he grew up.

5. A nail
Charlie was about to fight to the death with Richmond. Charlie asked a man to shoe his horse. When the blacksmith got the fourth shoe, there were still two nails missing to shoe the fourth shoe, so he did it secretly. Soon, Charlie and the other party were at war. Suddenly a horseshoe fell off during the battle. The king was thrown to the ground by the horse, and Henry captured Charlie.
So there is "two nails are missing, a horseshoe is missing, a horseshoe is missing, a war horse is lost, a war horse is lost, a battle is lost, a battle is lost. A battle was won and a country was lost.” 1% mistake led to 100% failure, and a huge dynasty was destroyed.
6. A thousand-mile embankment was destroyed by an ant nest
Since the 1970s, 13 embankments have collapsed and 9 dams have collapsed in Qingyuan, Guangdong. It has been verified that 9 embankments and 5 dams have collapsed. The dam is the result of soil termite damage.
In July 1986, a major flood occurred in Meizhou City, Guangdong Province since the founding of the People's Republic of China. 62 embankments of the Meijiang River burst, including 55 breaches caused by soil termites. In September 1981, the Moyang Embankment section in Yangjiang City, Guangdong Province broke out. Of the 18 gaps, 6 were confirmed to be caused by termites.
7. Noble gases
The Swedish chemist Scheele was originally an apprentice in a pharmacy. Due to his tenacious learning spirit and hard work, he discovered many gases and synthesized many organic matter.
When the British chemists Rayleigh and Ramkey measured the density of the gas, they found that the density of nitrogen produced from ammonium nitrite was different from that of nitrogen obtained by air separation, but the difference was only a few milligrams. Others tend to ignore it, but they carefully analyzed and studied it, further separated and measured it, and finally discovered the rare gas.
8. Replacement parts
On July 24, 2000, an Air France Concorde caught fire and crashed shortly after takeoff from Charles de Gaulle Airport outside Paris, killing 113 people. Subsequently, all Concorde aircraft owned by Air France and British Airways were grounded and inspected.
Further investigation showed that the metal flakes that fell on the runway were not original parts of the DC10 aircraft, but replacement parts that were replaced during maintenance of the aircraft's engine.
9. Subway Benefits
Shanghai Metro Line 1 was designed by the Germans and did not seem to have anything special until Line 2 designed by a Chinese designer was put into operation , only to discover that so many details were ignored by Line 2. As a result, the operating cost of Line 2 is much higher than that of Line 1, and it has not yet achieved break-even.
10. A piece of paper
Ford is a person. After graduating from college, he applied for a job in a car company. The three or four people he applied for were all more educated than him. After the first few interviews, he felt that he had no hope.
But once it comes, let’s make peace with it. He knocked on the door and walked into the chairman's office. As soon as he entered the office, he found a piece of paper on the ground at the door. He bent down to pick it up and found that it was a piece of stained paper, so he threw it into the wastebasket. Then he walked to the chairman's desk and said, "I'm here to apply for a job at Ford."
The chairman said: "Very good, very good! Mr. Ford, you have been hired by us." Ford said in surprise: "Chairman, I think the first three are better than me, how come you hired me?" The chairman said: "Mr. Ford, the first three are indeed better educated than you and have a good appearance, but Their eyes can only see big things, but not small things.
Your eyes can see small things. I think people who can see small things will naturally see big things in the future. A person who can only see big things, he. He will ignore a lot of little things. That's why I hired you.
