Find out and tell a story that inspired the little things in life to invent something

Stories of inventions inspired by the small things of life include:

1.After Lu Ban cut his finger by a blade of grass, he carefully observed the shape of the edge of the blade of grass and invented the saw.

2.Watt invented the steam engine by boiling rice steam on top of the pot.

Edison invented the gramophone due to the telegraph and **, the apple landed to discover the law of gravity, the psychic sense of flies, invented the hazard detector, and invented the steam engine in dangerous workplaces by boiling steam to open the lid of a pot.

Than Lu, you see that dogs have a keen sense of smell and want to invent olfactory devices.

Newton was smashed by an apple and discovered gravity.

Edison invented the gramophone for the telegraph and **, the apple landed on the ground to discover the law of gravity, the psychic sense of flies, the invention of the hazard detector, the gliding technique of the eagle in dangerous workplaces, and the invention of the glider.

The shape of the bird's line changes the shape of the aircraft and is more aerodynamic.

The bones of birds, which have improved the skeleton structure of the aircraft, are lighter and stronger.

Acoustic detection of bats and dolphins, the invention of ultrasonic radar.

Airplanes flying at night on radar are the inspiration people take from bats.

Watt invented the steam engine.

Archimedes discovered the law of buoyancy.

Edison invented the phonograph.

Boyle invented litmus paper.

Wegener said that he discovered land drifting.

Once, Edison was in a quiet laboratory researching and improving the telegraph that printed symbols on paper tape. At this moment, a monotonous voice in the telegraph attracted him. While trying to rehearse this sound, Edison unexpectedly discovered that it was the sound made by the paper tape under the pressure of a small shaft.

When the pressure of the small shaft is changed, the height of the tone also changes. This led him to the idea of using channels of different depths on the motion carrier to record and ** sounds.

Coincidentally, during another experiment**, Edison found that the diaphragm in the microphone vibrated with the voice. He found a needle, stood it on the diaphragm, gently pressed the upper end with his hand, and spoke to the diaphragm. Experiments have shown that the higher the voice, the faster the flutter; When the sound is low, the flutter is slow.

This discovery laid the foundation for the determination to invent the phonograph.

Watt invented the steam engine from the lid of a boiling kettle, Luban invented the juzi after being cut by grass, Archimedes discovered the law of buoyancy while taking a bath, Newton discovered the law of gravitation after being smashed by an apple, ......

The invention of the helicopter In 1907, the world's first Sunny Snake was successfully developed by French engineers Burleg and Riche. The aircraft had no wings, and the first arm head had two pairs of four-bladed propellers that rotated horizontally. When selling in the test flight bureau, it was found that the aircraft vibrated badly and had poor safety performance.

It was not until after 1932 that the former Soviet engineer Bratukhin designed and manufactured a high-performance aircraft called the "Omega". Since then, *** has gradually become an important flying tool. The invention of the rifle is excerpted from the first issue of "Big Science and Technology Encyclopedia Exploration" in 2008 In the development process of rifles, the rifle is a major breakthrough.

When firing, the back and forth lines in the barrel cause the bullet to constantly rotate as it flies, so that it can fly farther and have a higher hit rate. However, this major invention of science and technology is regarded as the ** of the demonic nerve, and a series of funny jokes are made. In 1510, the Austrian Casper Köllner discovered that feathered arrows should shoot far and have a high hit rate.

From then on, he was inspired to discover that the rifling in the barrel had a stabilizing effect on the bullet, so he invented the rifle, and some officers were not convinced, not believing that a few lines in the barrel could hit farther than the smoothbore gun, and proposed to test it on the spot. Körner, of course, was up for it. As a result, Köllner hit 5 shots at a distance of 100 meters, while the smoothbore gun in the officer's hand had only 5 shots and 2 shots.

The distance was pulled to 200 meters, and the smoothbore gun couldn't hit at all, but the rifle was still 5 shots and 4 hits, and the officers were convinced, and the crowd of ** also became a sensation. This game is a pass of ten, ten passes of hundred, and the rifle has become the most advanced **.

There are people who impress themselves in everyone's heart, and it is ...... that impresses meI remember when I was 6 years old, my mother took me to play in the community garden, looking at me was attracted by the colorful, purple and red flowers, and I couldn't help but run here and there, just when I was tired of playing, when I was resting on the chair, a butterfly flew over, and made an arc elegantly in the air, looking at such a beautiful butterfly, my curiosity also rose to the peak like a rocket launch, he guided me to chase the butterfly, running and running, I was obviously a little tired, I stopped and wanted to take a break and chase again, but in the blink of an eye, the butterfly was gone. At this time, I realized that I was lost, looked left and right, ** I didn't know, just when I was about to cry in a hurry, an old man came up to me, he had a white beard, bright eyes, black and thick eyebrows, and his face was full of wrinkles, but he looked energetic, and he looked like a middle-aged man from a distance. He saw that I was alone, so he quickly guessed that I was lost, so he said to me

Child, what about your mom and dad? "I....I can't find it....Mom and Dad. I said with a slight fear.

Grandpa....Here....What is it called? Seeing that I was a little scared, my grandfather said to me, "Don't be afraid, don't be afraid, this is Building 2 of Wannian Flower City."

That....Grandpa....Here away....Is the Third Ring New City still far away? "It's not far, it's not far away, just walk to that little pavilion!" "When I heard the directions home, I was ecstatic, turned around and wanted to go back.

Ay! Children! Grandpa take you there, you tell grandpa, your mother is a**?

In the garden of the waterwheel. "Okay, grandpa will take you there, go!" "My grandfather and I held hands, and soon we arrived at the watermill garden, where I saw my mother asking questions and eagerly searching.

I happily pounced on my mother, grandpa saw that I found my mother, smiled happily, I told my mother what happened, my mother hurriedly ran to thank the old man, the grandfather saw my mother's thoughts, so he waved his hand behind him, and walked towards the city of ten thousand years of flowers. To this day, the old man's every move is still deeply engraved in my heart, and I have never seen the old man again.

During the war, parents told a girl who had just started elementary school, "Hide in a cave and don't come out anyway." The obedient little girl did so.

Another parent said to a little sister in kindergarten: "Hide in a cave, if someone comes, run away." "After the battle, it was found that only one girl had survived.

A little sister in kindergarten heard the enemy's footsteps and ran away. And the other girl, who listened to her parents, hid in a cave and did not understand, as a result she was killed. Just because of a word, the girl listened, and she died.
