1. Albert Einstein.
Once, Albert Einstein asked his mentor Minkowsky: "How can a person, like me, leave his own shining footprints and make himself in the field of science and on the road of life?"
What about outstanding contributions? Minkowski said that he would think about it and answer it later. Three days later, Minkowski picked up Einstein and headed for a construction site, and he went straight to the ground.
The concrete floor that the builders have just paved. Amid the shouts of the construction workers, Einstein was confused and asked Minkowski in confusion: "Teacher, didn't you lead me into a mistake."
way'? "Yes, yes, exactly! Minkowski said
See? Only the cement pavement that has not yet solidified can leave deep footprints. Those old roads that have been frozen for a long time, those places that have been walked by countless people and countless footsteps, you don't want to step on the footprints again......Hearing this, Einstein pondered for a long time and nodded meaningfully.
Since then, a very strong one.
The sense of innovation and pioneering began to dominate Einstein's thinking and actions. In his own words, "I never memorize or think about dictionaries or manuals, my head only uses them."
Remember and think about things that aren't in books yet. "Albert Einstein made outstanding contributions to mankind and left a deep and shining footprint in the annals of science.
2. Napoleon broke the rules.
After his defeat at the Battle of Waterloo, Napoleon was exiled to St. Helena for life. He lived a very lonely and lonely life on the island. Later, a close friend of Napoleon's secretly gave him a pair.
Chess. This famous prisoner was so fond of the elaborate and precious chess that he often played it silently alone, helplessly passing the time of loneliness and loneliness until slowly.
Die. After Napoleon's death, the chess set changed hands many times. One day, the chess holder stumbled upon the fact that the bottom of one of the chess pieces could be opened. When the person opens.
At the bottom of this chess piece, I couldn't help but be stunned, and there was a detailed plan for how to escape from St. Helena Island densely written inside. However, Napoleon did not learn from chess the good use of his friends.
Hearts and mysteries in chess. Napoleon probably never dreamed that he would end up dying in the trap of conventional thinking. If he can think about it with the thinking method of not tiring deceit during the war in the south and the north.
For all the other functions that chess may entail, God is likely to congratulate and smile at him again.

1. The story of Lu Ban's invention of the saw, according to legend, one year, Lu Ban accepted a task to build a huge palace. The palace needed a lot of wood, so he and his apprentices had to go up the mountain to chop wood with axes, and there were no saws at that time, which was very inefficient. Once, when he was going up the mountain, because he was careless, he inadvertently grabbed a handful of wild grass growing on the mountain, but he cut his hand at once.
2. Lu Ban is very strange, why is a small piece of grass so sharp? So he plucked a leaf and looked closely, and found that there were many small teeth on both sides of the leaf, and when he touched it lightly with his hand, these small teeth were very sharp. He understood, his hand had been cut by these tiny teeth.
Later, Lu Ban saw a big locust gnawing on a grass plant, and the two big teeth were very sharp, opening and closing, and soon ate a large piece.
3. This also aroused Lu Ban's curiosity, he grabbed a locust, carefully observed the structure of the locust's teeth, and found that the locust's two large teeth were also lined with many small teeth, and the locust relied on these small teeth to bite off the blades of grass.
4. These two things gave Lu Ban a lot of inspiration. So he used the big bamboo to make a bamboo piece with many small serrations, and then went to the small tree to do the experiment, the result was really good, a few strokes of the tree pole to draw a deep ditch, Lu Ban was very happy. However, because the bamboo piece is relatively soft and the strength is relatively poor, it cannot be used for a long time, and after pulling for a while, some of the small sawtooth is broken, and some become dull, and the bamboo piece needs to be replaced.
5. Lu Ban thought of the iron piece, so he asked the blacksmith to help make the iron piece with small serrations. Lu Ban and his apprentice each pulled one end and pulled it up on a tree, only to see them go back and forth, and after a while, the tree was sawn off, quickly and labor-saving, and the saw was invented.

Luban saws: Legend has it that once when Luban went into the mountains to cut trees, he was careless, his hand was cut by the leaves of a weed, Luban picked the leaves and touched them gently, it turned out that there were sharp teeth on both sides of the leaves, and the hands were cut by these small teeth, Luban also saw a big locust on a weed, and there were many small teeth arranged on the two large teeth, so the leaves could be quickly grinded. Lu Ban was inspired by these two things.
After many experiments, the sharp saw was invented, which greatly improved the work efficiency; Percussion was born: In the 18th century, an Austrian doctor died suddenly when he was treating a patient before he could diagnose it. Upon autopsy, his chest cavity was found to be purulent and pus-pognated.
One day, in a hotel, the doctor saw the guys moving the barrels, and I saw them knocking on this barrel and knocking on that barrel.
