Inventor celebrity story: the invention story of autonomous driving

Nowadays, self-driving has spread all over the world and entered thousands of households, but the invention process of self-driving is very tortuous. Few people know that self-driving was invented by a German ranger named delaisse (1785- 185 1).

On a rainy day, Sifrak, a Frenchman, was splashed with mud by a passing carriage while walking in the street. This splash made him suddenly think: the carriage is so wide, it should be cut in half, and four wheels will become two wheels ... So, the first Trojan wheel car was born in 179 1. This car has two wooden wheels, front and back, with a beam in the middle and/kloc-0 benches on it, like a toy. The new things that have just appeared are definitely not so perfect. This "wooden horse wheel" has neither a transmission chain nor a steering device, so it naturally needs to be improved.

Delaisse used to be a forest ranger. He had to walk from one forest to another every day. Years of hard work on foot aroused his desire to invent a means of transportation. He thought: If people can sit on wheels, they will walk faster! In this way, delaisse began to design and manufacture self-driving cars. He made a unicycle with two wooden wheels, a saddle and a handlebar, which is connected to the front wheel for control. People sit in cars and drive wooden wheels outdoors with their feet. In this way, the world's first self-driving car came out.

18 17, delaisse rode his bike for the first time and was ridiculed all the way ... He was determined to answer this ridicule with facts. In a race, he rode his bike for 4 hours, while the horse-drawn car took 15 hours. Despite this, no manufacturer is willing to produce and sell such self-driving cars.

Delaisse also invented the meat grinder and typewriter, which can reduce the labor intensity. At present, the tram that railway workers push by manpower on the tracks was also invented by delaisse, so it is called "delaisse".

1839, a native of Scotland, Macmillan, invented the pedal and installed it on the front wheel of an autonomous vehicle, which greatly improved the autonomous driving technology. In the following decades, a variety of self-driving vehicles emerged, such as windsurfing self-driving, water treadmill, ice self-driving, five-wheel self-driving and so on, and self-driving gradually became a popular means of transportation. In the future, with the emergence of pneumatic tires and chains, the structure of self-driving vehicles is becoming more and more perfect.

1840, the British blacksmith Macmillan improved the pony invented by delaisse. He installed a crank on the axle of the rear wheel, and then connected the crank with the front pedal with a connecting rod. The front and rear wheels were made of iron. The front wheel is big and the rear wheel is small. In this way, people's feet really leave the ground, from the alternate trampling of feet to the rolling of wheels. 1842, Macmillan got on this car and ran 20 kilometers a day.

In 186 1 year, Messau and his son in France installed rotatable pedals on the front wheel, and the saddle of the car was installed above the front wheel. They dubbed the car "self-driving", and it appeared at the Paris Expo in 1867, which opened the eyes of the audience.

From Sifrak to Renault, their self-driving cars are very different from modern self-driving. The truly modern self-driving car was born in 1874. Luo Song, an Englishman, ingeniously installed chains and sprockets on his self-driving car, and used the rotation of the rear wheel to propel the car forward. But it is still not coordinated and stable enough.

From 65438 to 0886, British mechanical engineer stahly designed a new automatic driving style from the perspective of mechanics and outdoor science. The front fork and brakes were installed, and the front and rear wheels were the same size for continuous balance. He made a diamond-shaped frame out of steel pipes and used rubber wheels for the first time. Stahly not only improved the structure of automatic driving, but also transformed many machine tools for producing automatic driving parts, which opened up a broad road for the overproduction, popularization and application of automatic driving, so he was called "the father of automatic driving" by later generations. The self-driving model he designed is basically consistent with the appearance of self-driving on this day.

Human wisdom is really everywhere. 1888, Irish veterinarian Dunlop was inspired by the treatment of cattle flatulence. He glued the rubber hose for watering his garden into a circle, and then pumped it into the self-propelled vehicle, which was the beginning of pneumatic tires. Pneumatic tire is an epoch-making pioneering work in the development history of autonomous driving, which not only fundamentally changes the riding performance of autonomous driving, but also improves the use function of autonomous driving.

From 179 1 to 1888, the invention and improvement of self-driving motorcycles have experienced the unremitting struggle of these inventors for nearly 100 years. We must be moved by human inventions.

Story 2:

The story of a famous inventor: Edison's scientific invention story

1one morning in the autumn of 877, Edison came to the office of a magazine revision department in new york from a place called Mero Village in the United States. He noticed a strange little thing in his arms. This little thing has a long metal bar on it, with a big wheel at one end and a small handle at the other. Edison turned the handle, then wrapped a small piece of tin foil on the cylinder, put a small needle on it and sang a baby hypnosis song to the cylinder. After the action, the machine turned again, and it sang a hypnotic song word for word. It is not enough to describe the first feeling of the people present at that time, only to say surprise. People were so happy that everyone in the revision department told each other loudly that Edison had brought a talking monster. In a short time, reporters from newspapers in the city flocked to see the latest strange machine in the world, and the newspapers were packed for a time.

Once this invention came out, it aroused the rapid and huge fanaticism of the society for several months at that time. The railway specially opened a special car to visit. Many people didn't believe this invention at first, and suspected that he had hidden something talking in it to deceive people. A bishop of a church recited a series of special terms in the Bible at the highest speed on the radio. When these terms are repeated word by word from the machine, they firmly believe that there is nothing false. This is the scene when the world's first phonograph came out. While people are admiring, they all call the inventor Edison "the devil". In fact, the nickname "the devil" is far from the invention of the phonograph, but has been with him all his life. It is precisely because he invented too many things. Electric light, telephone, film, telegraph, generator, storage battery, typewriter, magnet separator, pressure gauge and so on are all his inventions. According to incomplete statistics, since he invented the first automatic counting machine from 1869 to 19 10, he has obtained 1328 kinds of invention patents, which means that he has an invention every1kloc-0/day during this period. Because of this, naturally some people call him a "demon".

However, where does the real magic of this "devil" figure come from? He said to himself, "One part inspiration, ninety-nine parts sweat". "tenacious perseverance and amazing diligence are his real' magic'." Source: www.binzz.com Reprinted, please keep this source, thank you!

Thomas? Edison, born in 1847, is from Oahu, USA. He has only been in primary school for three months. The school teacher called him "stupid", so did his relatives and friends. But his mother didn't believe this, so she became his teacher and guided him to read some books. Less than 12 years old, he finished reading many difficult books, and his father also instructed him to study Newton's principles. The education and influence of his family made him develop a diligent spirit and amazing perseverance from an early age.

Edison loved science very much. When he was very young, he stored hundreds of bottles in my cellar for various experiments and built a small laboratory. He spent all the money he usually saved by scrimping and saving on buying chemical supplies and instruments. But the money alone could not meet the needs of the experiment, so he went to the train to sell newsboys. He gets on the bus every morning and goes home after 9 pm. After finishing the experiment, he often stays up late at night. Later, he found that there was a smoking room in the luggage compartment of the train, so he moved his experiments in the cellar to this place and insisted on doing chemical experiments. There, he also learned and understood the use of printers here. He could record local news with telegraph numbers and started a newspaper. This newspaper is very popular and sells well. At this time he was only 12 years old. One day, the train shook, the luggage slipped down, a phosphorus pole he used for his experiment fell to the ground, and the carriage caught fire at once. The fire was put out by the people who rushed to the scene, but the conductor deafened his ears and caused lifelong disability. The conductor also kicked everything in his "four-wheeled laboratory" and "travel printing room" under the car.

Difficulties and setbacks did not affect Edison's determination to engage in scientific experiments. He built a laboratory at home. Being electrocuted and burning clothes are common in experiments. Once, his face was badly burned by nitric acid. Nevertheless, he never loses heart. Edison's earliest efforts contributed a lot to his later inventions. However, like other great inventors, Edison's road was not smooth. He is a night telegraph operator. Spend a lot of energy in book stands and libraries. However, due to unemployment several times, I finally had to go to new york to reunite with my brothers and sisters.

Edison took the trouble to come to new york. At this point, there is not even a penny in his pocket. He was so hungry that he had to beg for some tea, which was his first meal after he arrived in new york. There, it took him a long time to find his brothers and sisters, but his brothers and sisters also lost their jobs. Edison, who suffered from hunger, was looked down upon because of his poor appearance and rags. After that, he was allowed to spend the night in the battery room. There happens to be a communicator in the room that announces the market price. On the morning of the third day he arrived, the machine broke down. Because he studied hard, he quickly helped others repair the machine and was left behind, so he found a job. From then on, he worked hard, cooperated with other people's reforms, and got ahead by market price communication machine. Soon, he opened a small factory to produce this kind of communication machine and gradually embarked on the road of scientific research.

Story 3:

Inventor of ballpoint pen

Hungarian journalist Biro accidentally cut the manuscript paper when he was writing it. He thought it would be nice to change the nib into a ball. (WeChat signature)

So Biro went to consult chemist Okey. Okey said: "It is ok to change the nib into a ball, but you can write only if there is ink leakage around the ball!" "

Biro thought, isn't it enough to control the flow of ink when the ball rotates? He began to experiment repeatedly.

1943, Biro finally invented a new pen-ballpoint pen, which emits ink by the rotation of the ball.

Ballpoint pen is very convenient and cheap to use, so it quickly became popular all over the world.

Story 4:

Benediktus and "Safety Glass"

Benedetz is a famous French chemist. An accidental opportunity triggered his inspiration and made him research and produce "safety glass".

Yes 1907. One day, Benedetto was sorting out instruments in the laboratory and accidentally knocked over a glass bottle. This is the end! The floor of the laboratory is paved with stones. Won't the glass bottle break into pieces when it falls? However, to his surprise, the bottle did not break into pieces, but there were some cracks. He took out a washed bottle and dropped it gently on the ground. This time, the glass bottle was smashed to pieces. Why are the conditions of the two bottles so different? Benny Ditters has a hard time finding the answer.

A few days later, the newspaper reported that a car accident was cancelled, and the flying glass fragments hurt the passengers, which made Benedetti deeply sad. He couldn't help thinking of the broken bottle and determined to get to the bottom of it. He found the bottle again and observed it carefully. It turned out to be a bottle with some medicine. After the medicine evaporates, a tough and transparent film is formed on the inner surface of the bottle. It seems that this membrane protects the bottle.

This "accidental" discovery prompted him to further study the glass coating. After many experiments, he finally found a suitable coating with strong adhesion and good transparency. Later, he used paint to bond the two layers of glass together, and found that its anti-breaking performance was better. In this way, "safety glass" was finally born.

Story 5:

Fleming and penicillin

At present, penicillin has been widely used in medicine. It can kill germs and eliminate inflammation and infection. Maybe, you don't know, penicillin was discovered by accident!

1928 September, British bacteriologist Fleming was studying staphylococcus, a bacterium that can make people sick. In order to study the living habits and pathogenic mechanism of this pathogen, it is necessary to cultivate and observe it. At that time, the equipment was relatively simple, and the work was carried out in a hot and humid old house. During the experiment, the Petri dish needed to be opened many times, so the culture in the Petri dish was easily polluted. Once, Fleming opened the Petri dish to observe the bacteria. Blue-green mold occasionally grows on the mouth of the Petri dish. Next to the mold, staphylococcus melts and clear water drops appear.

Why can blue-green mold inhibit the growth of bacteria and destroy them? Fleming firmly grasped this "accidental" discovery, went all out to study this blue-green mold, and finally found the nemesis of staphylococcus-penicillin, and further found that it also had a killing effect on other germs.

1945, Fleming, who discovered penicillin, won the Nobel Prize in Physiology and Medicine together with English pathologist Flory and German chemist Ernst Boris Chane, who developed penicillin chemicals.

Story 6:

Bell invented the telephone.

Bell is the man who invented the telephone. He was born in England on 1847. When he was young, he and his father taught the deaf together. He wants to make a machine that can make deaf people see sound with their eyes.

1873, Bell, who became a professor at Boston University in the United States, began to study the device of transmitting multiple telegrams on the same line-multi-task telegraph, and sprouted the idea of transmitting people's voices to far away places with electricity, so that people thousands of miles away could talk face to face. So bell began to study the telephone. (Good morning)

That was June 2nd, 1875. Bell and his assistant Watson are experimenting with multiplex telegrams in two rooms respectively. An accidental accident inspired Bell. In Watson's room, there is a spring stuck to the magnet of the telegraph. When Watson pulled it away, it shook. At the same time, Bell was surprised to find that the spring on the telegraph in his room vibrated and made a sound. It is the current that transmits vibration from one room to another. Bell's mind suddenly broadened. He thought: If a person speaks to a piece of iron, the sound will cause the iron to vibrate; If an electromagnet is placed behind the iron sheet, the vibration of the iron sheet will inevitably produce large and small currents in the electromagnet coil. This fluctuating current travels far away along the wire, so won't the same vibration and sound appear on similar equipment in the distance? In this way, the sound travels far away along the wire. Isn't this the dream phone!

Bell and Watson made the telephone according to this new idea. In an experiment, a drop of sulfuric acid splashed on Bell's leg, which made him cry. "Mr. Watson, I need you. Please come to me! " "This sentence reached Watson's ear by telephone through wires, and the telephone succeeded! 1On March 7th, 876, Bell became the patentee of telephone invention.

Bell Life has obtained 18 patents, and cooperated with others to obtain 12 patents. He envisions burying telephone lines in the ground or hanging them in the air, and connecting them to houses, villages and factories ... so that you can make phone calls directly from anywhere. On this day, Bell's vision has already become a reality.

Story 7:

Johannes Gutenberg (German)

The most famous invention: modern printing

Johannes Gutenberg wants to piece all the little things together to make a movable type printing machine. Before you realize the fact that his printing may set off an information revolution, you will feel that his idea seems a little less great.

None of us know who wrote the Bible, but we know the name of its publisher: Gutenberg. Yes, China's movable type printing has been used for hundreds of years before, but Gutenberg was the first to print words into books instead of silk. This innovation enabled a wider range of people to access knowledge, thus giving birth to the "Enlightenment Age". Gutenberg is one of the best inventors, but as a businessman, he is unfortunate. His printing changed the world, but it didn't make him rich. He even lost the right to invent this technology in a lawsuit against his own expense.

The coolest fact: In the debt-ridden predicament, Gutenberg spent his old age working for the Archbishop of Mainz, who brought him room and board and helped him quit the habit of drinking.

Story 8:

James watt (UK)

The most famous invention: the improved steam engine

We won't use steam as the main energy source on this day, but back in the early days of the industrial revolution, steam was a time to show off. James watt spent a lot of time improving the steam engine and pushing the world forward.

Watt didn't invent the steam engine, but he could make it work for people. In fact, it was Watt's innovation and improvement that changed the world from agriculture to industry. In addition to making such a great contribution to power and machines, Watt also invented a rotating machine and a device called "flying ball", which can automatically adjust the speed of the machine.

The coolest fact: the unit of power "Watt" is named after him, and he has always been recognized as the greatest engineer in the world.

Story 9:

Benjamin Franklin (USA)

The most famous invention: bifocal glasses

We all know that reading is fundamental, but reading is the premise of reading. Thanks to the bifocal glasses invented by Benjamin Franklin, even people with vision less than 20/20 can browse the web pages of websites. While writing the Chronicle of Poor Richard, helping the United States win the recognition of France (which reversed the situation of the American revolution) and pleasing girls everywhere, Franklin still made a very important contribution to science. Many of us may remember the photo of him flying a kite in the storm in the social studies class. This experiment taught Franklin a lot about electricity and brought us a lightning rod.

The coolest fact: Inventors and stallions (boys who like to pursue girls) usually don't involve the same person, but Benjamin Franklin is an exception. He is the most likable boy of his time, and his popularity among French girls is very beneficial to the cause of the United States.

Story 10:

Isaac newton (UK)

The most famous invention: calculus

If you finally try to finish the advanced mathematics course, you may not be a big fan of Sir isaac newton, because all the problems you encounter are basically his fault-he invented calculus.

If you understand physics at the moment, whether you are talking about gravity (a story about an apple falling from a tree, whether true or false, is a powerful example) or the principle of light and optics, you have to start with Sir isaac newton's research results. Newton was the first to propose that "light is composed of particles", which led him to develop the reflecting telescope (now named after him). In addition, Newton also made contributions to the study of acoustic and thermal principles.

The coolest fact: It is easy to think that scientists are just a group of laboratory mice who don't care about the world, but Newton is an exception: he has been a king's judge of England for nearly two years and is engaged in the execution of counterfeiters. At the end of his legal career, he still has 10 criminals to be executed.
