Router speed of Monroe mining machine
IPFs is a file transfer protocol similar to http. If IPFs wants to run, it needs many computers (storage devices) in the network as nodes. In a broad sense, all participating computers can be called IPFs mining machines
in order to attract more users to join the IPFs network and contribute to the network, an encryption currency named filecoin is designed, which is distributed to the participants (nodes) as a reward according to the amount of contributed storage space and bandwidth. In a narrow sense, the computer specially designed for the purpose of obtaining the filecoin reward is called IPFs mining machine
because IPFs network needs storage space and network bandwidth, in order to obtain the highest profit ratio, IPFs mining machine usually strengthens the storage space and reces the power consumption of the whole machine. For example, more than 10 high-capacity hard disks are equipped, Gigabit or higher speed network cards are equipped, and ultra-low power architecture processors are used
of course, the mining machine provides storage services, so it can obtain revenue. The size of revenue is related to the configuration of mining machinery and the number of IPFs mining machinery
extended data
the reasons why it is not recommended to invest in IPFs are as follows:
1. IPFs technology is too early to be commercialized
IPFs now takes up a lot of bandwidth. IPNs is very slow at present, which is an obvious technical defect. It will be very difficult to realize dynamic web pages only through IPFs
There is no reasonable economic model, even if the token economy is added, it is difficult to realize the long-term natural ecological valueas a very cumbersome decentralized protocol, it is difficult for users to share files autonomously and spontaneously. In addition, even if users share files into the protocol, the files will be completely open and users cannot delete files effectively, so the security of valid files is threatened
the solution is to introce encryption and blockchain incentive mechanism. At the same time, it solves the security and storage power problems of files. However, as mentioned before, any node with workload proof under blockchain incentive mechanism will face an economic problem of continuous power on state
It is difficult to establish an ecological network with IPFs as the core under the influence of technical problems The ecological application space ofIPFs is quite limited, and the project interaction speed realized by IPFs protocol is also very slow. Of course, it has a direct relationship with the number of nodes and the distance of calling
At the end of March this year, bitmainland launched an ant miner X3 based on ASIC, which is mainly aimed at Monroe coin (XmR) and cryptonight algorithm dependent cryptocurrency. Monroe coin immediately issued a counter statement that it will change the core algorithm to fight against the invasion of ASIC computing power
what would be the result if it appeared in the world of digital cryptocurrency? That is, the wrong calculation results may be brought into the whole network without being discovered
More importantly, if a "calculator manufacturer" monopolizes the calculator market, it can also deliberately proce this kind of calculator with errors to change the mathematical rulesafter all, the "calculation" in the field of crypto digital currency is not as simple as 1 + 2 + 3. You can't compare paper currency with special currency by hand
the practical significance of computing power monopoly in mainland China
we have learned about attacks based on 51% computing power in various articles
but the reality is that although the global power of 78% was in Chinese mainland, fortunately, they were scattered in different pools and controlled by different people. p>
although all POW based cryptocurrencies have the risk of being attacked by 51%, few people can really launch attacks e to the dispersion of computing power
but what if the miners themselves don't want to attack, but the mining machinery manufacturers attack
still using the analogy just now, although each miner subjectively wants to do the problem checking independently, their calculator is manipulated remotely and gives consistent wrong answers. This may pose a great threat to digital cryptocurrency
however, the manufacturer with the absolute voice of mining machinery had such a problem in mainland China
in April 2017, the back door of antbled came out. Although this is described as a "vulnerability" in Chinese, antbled is more like a function that has been implemented and designed
anonymous people found that after an ant miner made by bitmainland was connected to the network, it would communicate with a domain name held by bitmainland on a regular basis and return the miner's serial number, MAC address and IP address to bitmainland's server. If the server of bitcontinent gives a negative signal, the miner will stop running
although bitcontinental responded that they could not shut down any mining machines that did not belong to them. However, the bitcoin core team has proved in experiments that this function has no verification. Anyone can shut down mining machines by forging DNS - but it also means that bitcoin mainland has the ability to shut down any sold mining machines
After, bitcontinent fixed this "loophole", but it caused heated discussion in the community. This has also set the tone that almost all pow blockchain communities are biased against mainland China
a few months later, under the leadership of bitcontinent, viabtc g out the first block and made a hard bifurcation with the blockchain of bitcoin. From then on, bitcoin BCH (bitcoin cash) appeared in the world
will the monopoly of mining machinery destroy the distributed system
facing this problem, we should have a clear answer now. That is, the monopoly of mining machinery will certainly affect the safe operation of pow digital cryptocurrency
the problem is not whether bitcontinental and its founder Wu Jihan are trustworthy, but that one of the values of any blockchain system is to operate safely without trust in any single company or indivial
even if the ASIC miner is not monopolized by bitmainland, the ASIC miner itself will increase the concentration of computing power
the ASIC used for mining has great requirements for ventilation, power and site, and has no use except for mining. At the same time, the calculation difficulty of the whole network is increased e to the powerful computing power
as a result, it is very difficult for external players to start mining in the next software on the computer as they did five years ago. And the recent centralized exchange is caused by frequent black incidents, which also proves that concentration in this unregulated market will definitely lead to insecurity
assuming that the bitcoin network runs on top of one million miners, no one can shut it down. And if the bitcoin network runs on 20 large mines, it's much easier to shut it down
and by the end of 2017, 78% of the effort was concentrated in mainland China, which led to a real possibility of Chinese mainland regulators' launching a deadly attack against the special currency. p>
moreover, most of the scenarios of using digital cryptocurrency are related to "decentralization". Once centralized, it means that these scenarios no longer exist. It turns a project that might have value into a pure waste of computing power
Then, what measures should we take in the face of this situationfirst of all, as the project side, it may be time to give up the pure POW mechanism. In fact, in many projects of issuing cryptocurrency, especially in asset securitization projects. Similar to the concept of stock in the real world, POS itself is more reasonable than pow
in the media that don't know about blockchain, we often hear such words as "bitcoin wastes a lot of computing power and has no value", which is reasonable to some extent. It is difficult for a POW based blockchain to bind the value of the project itself to the issued digital cryptocurrency - because the real value behind the price of the currency does not come from the project, but from the cost of maintaining computing power
and the hybrid mode of pow + POS is more like the future. In the hybrid mode, both coin holders and miners can participate in the major decisions of this community. If a decision is widely accepted, the blockchain will be soft forked to the latest state without excessive intervention of developers, and there will be almost no private resistance of miners or mining machines
secondly, as a retail miner, if you are still digging a pure POW mechanism currency, you should unconditionally support the bifurcation activities initiated by the community to resist the ASIC mining machine, even if it will lead to the failure of your mining machine
this may sound contradictory, but in the long run, it is better to promote the reform of the community and get more benefits in a currency controlled by the monopoly of computing power. Because in many conflicts between computing power and community in the past, the ultimate result is that the computing power owner will forcibly keep the old algorithm to hard fork the blockchain
just like Eth and etc, the classic Ethereum (etc), which belongs to the computing power master, has lost the support of developers and become an air coin with no vitality and impossible to develop applications
as a retail leek, you should be careful to trade the non mainstream digital currencies (except bitcoin) supported by bitmainland mining machinery, so as to avoid falling into a blockchain in which bitmainland controls the computing power completely
finally, if you are bitcontinent, what should you do
bitcontinent's goal is to become Intel, AMD and NVIDIA, make greater contributions to the whole computer instry, and become a great company, not just entangled in the immediate interests of mining
Wall Street financiers have long seen through the violence brought about by NVIDIA's video card mining. The rise and fall of the company's stock price has been consistent with the price of bitcoin, and even affected by the digital currency market. Citron, a well-known short seller, has recently been bearish on NVIDIA, arguing that the company has focused too much on providing services for digital currency miners rather than on serious businesses such as artificial intelligence, games and driverless driving
the mission of chip manufacturers is to provide more powerful chips to drive more intelligent services, and finally contribute to the real world, rather than become monopoly tycoons in the virtual world. When we no longer enter the gate of the virtual world, the only thing left is a deserted land
in an interview with US media last year, Wu Jihan disclosed that he would make an IPO with a market value of billions of dollars. As a company about to go public, bitmainland should not only be responsible to investors, but also accept investors' questions about the sustainability of its business. "If your mining machinery goes public, it will encounter a fork, what should you do?"
and this question, which needs to be asked after the listing, has already appeared: the current price of the split coin xmo after the Monroe team split is $7.50, while the current price of the real Monroe coin XmR is $194, and the split coin is completely abandoned by the Monroe community
before bitcontinent becomes the name of all blockchain communities, we can rely on the huge amount of capital accumulated in recent years to transform into an artificial intelligence chip company along the previous plan, rather than continue to develop a variety of digital currency mining machines to extract the last drop of oil before the ecological collapse

Graphics card digging Monroe is really better than other currencies, the income will be higher! Of course, digging eth is also a good choice
this is my own video card miner. The mining software uses ha Yu miner , (the reason why I choose this software is that ha Yu does not pump water ) there are about 12 pieces per day
in China, the digital currency issued by the central bank will coexist with the paper currency for a long time, until the paper currency is graally replaced by the digital currency. Of course, digital currencies such as bitcoin, Leyte and decent can only exist as a supplement, and cannot become the mainstream.
Edison only went to primary school for three months in his life. His knowledge came from his mother's teaching and self-study. His success should be attributed to his mother's understanding and patient teaching since childhood, which made Edison, who was originally regarded as an incompetent child, become a world-famous "king of invention" when he grew up
Edison was curious about many things since he was a child, and he liked to experiment with them himself until he understood the truth. When he grew up, he devoted himself to research and invention according to his own interests. He set up a laboratory in New Jersey and invented more than 2000 kinds of things in his life, such as electric lamp, telegraph, phonograph, video camera, magnetic separator, crusher and so on. Edison's strong research spirit made him make great contribution to the improvement of human life style
"waste, the biggest waste is to waste time." Edison often said to his assistant“ Life is too short. Think more and do more with less time. "
one day, Edison was working in the laboratory. He handed his assistant an empty glass bulb without a light port and said, "you measure the capacity of the bulb." He bowed his head to work again
after a long time, he asked, "what's the capacity?" He didn't hear the answer. He turned his head and saw his assistant measuring the perimeter and inclination of the bulb with a tape measure. He took the measured number and put it on the table to calculate. He said, "time, time, how do you spend so much time?" Edison came over, picked up the empty light bulb, filled it with water, handed it to his assistant, and said, "pour the water in the measuring glass, and tell me its capacity right away."
the assistant immediately read out the number
Edison said, "what an easy way to measure. It's accurate and time-saving. Why can't you think of it? Is it not a waste of time? "
the assistant blushed
Edison murmured: "life is too short, too short. Save time and do more things!"< Before he became famous, Edison was a poor worker. Once, his old friend met him in the street and said with concern, "look, this overcoat on you is not in good condition. You should replace it with a new one."
"do you need it? No one knows me in New York Edison answered with indifference
a few years later, Eddie has become a great inventor< One day, Edison met his friend on the street of New York“ "Oh," exclaimed the friend, "Why are you still wearing this old coat? This time, you need a new one anyway
"do you need it? Everyone here already knows me. " Edison still answered with indifference.
Edison was also a great entrepreneur. He founded Edison General Electric Company in 1890, whose two main businesses formed the famous general electric company (GE)<
Life
Edison was born on February 11, 1847 in the small town of Milan, Ohio, in the Midwest of the United States of America. His father is a descendant of the Dutch, and his mother, a former primary school teacher, is a descendant of the Scots. When Edison was seven years old, his father lost money in the tile business and moved his family to Fort gratiott, a northern suburb of Huron, Michigan. Soon after he moved here, Edison suffered from scarlet fever, which is believed to be the cause of his deafness. Edison went to school at the age of 8, but after only three months of reading, he was expelled from school by his teacher as an "imbecile". From then on, his mother was his "tutor.". Because of his mother's good ecation method, he became interested in reading“ He not only read extensively, but also read everything at a glance. At the age of 8, he read the works of William Shakespeare and Dickens, the most important playwrights of the English Renaissance, and many important historical books. At the age of 9, he could quickly read more difficult books, such as nature and experimental philosophy by Parker. When I was 10 years old, I loved chemistry. At the age of 11, he experimented with his first telegram. In order to make money to buy chemicals and equipment, he began to work. At the age of 12, he got a job selling newspapers on trains, traveling between Port Huron and Detroit, Michigan. He sells newspapers while doing fruit and vegetable business. Whenever he has time, he goes to the library to read. He bought an old printing press and began to publish his weekly, the herald, the first of which was printed on the train. With the money he earned, he set up a chemical laboratory on the luggage cart. Unfortunately, once a chemical caught fire and he and his equipment were thrown out of the car. Another time, while Edison was trying to get on a freight train, a conctor grabbed his ears to help him get on. This action led Edison to be deaf for life< In August 1862, Edison rescued a boy who was about to die on the track of a train. The father was grateful for this, but he was willing to teach him telegraph technology because he had no money to pay for it. From then on, Edison had a relationship with this mysterious new world of electricity and embarked on the journey of science< In 1863, Edison worked as a telegrapher at Stratford junction station of the main line railway. From 1864 to 1867, he worked as a telegraph operator in the central and western regions and lived a life similar to wandering. The footprints include Stratford, Adrian, Fort Wayne, Indianapolis, Connecticut, Nashville, Tennessee, Memphis, Louisville and Huron< In 1868, Edison came to Boston as a telegraph operator. In the same year, he obtained the first patent for invention. This is an automatic voting device. Edison thought the device would speed up the work of Congress, and it would be popular. However, one congressman told him that they had no intention of speeding up the agenda and that sometimes voting slowly was out of political need. From then on, Edison decided not to invent anything that people didn't need< In early June 1869, he came to New York to look for a job. While he was waiting for a call in an agent's office, a telegraph broke down. Edison was the only one there who could fix the telegraph, so he got a better job than he expected. In October, he and Popper set up a "Popper Edison Company" to specialize in scientific instruments for electrical engineering. Here, he invented the "Edison universal press". He dedicated the press to the manager of a big Wall Street company. He wanted to ask for $5000, but he didn't have the courage to say it. So he asked the manager to give him a price, and the manager gave him $40000<
Edison used the money to build a factory on ward street in Newark, New Jersey, specializing in various electrical machinery. He works all night. He trained a lot of capable assistants. At the same time, he ran into the diligent Mary Stilwell, his first bride in the future. In Newark, he made such inventions as wax paper and mimeograph. From 1872 to 1875, Edison invented the double Telegraph and quadruple telegraph, and helped others build the world's first English typewriter< In the spring of 1876, Edison moved to "Monroe Park" in New Jersey. He built the first "invention factory" here, which "marks the beginning of collective research". In 1877, Edison improved the telephone invented by Bell and put it into practical use. He also invented his favorite project, the phonograph. Telephone and Telegraph "is a revolution to expand human sensory function"; Gramophone is one of the three great inventions that changed people's lives. "From the perspective of invention imagination, this is his extremely important invention achievement.". By this time, people called him "the magician of Monroe Park"< On October 22, 1879, Edison ignited the first electric lamp with wide practical value. In order to extend the life of the filament, he retested, and tried out more than 6000 kinds of fiber materials before finding a new luminous body, Japanese bamboo silk, which lasted for more than 1000 hours, and achieved a rable purpose. In a way, this invention is the highest achievement of Edison's life. Then he created a power supply system that allowed distant lamps to be distributed from a central power station, a major technological achievement
his first discovery in pure science appeared in 1883. When experimenting with electric lamps, he observed what he called the Edison effect: an electric charge in the lighted bulb passes through space from the hot filament to the cold plate. Edison patented the discovery in 1884, but did not study it further. Other scientists used the Edison effect to develop the electronic instry, especially radio and television
Edison tried to do what the phonograph did for the ear for the eye, and the film camera was born here. Using a new Celluloid film invented by George Eastman, he took a series of photos and projected them onto the screen quickly and continuously, creating the illusion of movement. He first experimented with films in the laboratory in 1889 and patented them in 1891. In 1903, his company proced the first feature film "train robbery". Edison did a lot of work for the formation and standardization of the film instry< After Edison moved his laboratory to West Orange in 1887, he founded many commercial companies to make procts and promote sales for his various inventions; These companies later merged into Edison General Electric Company, later known as general electric company. Since then, his interest has shifted to fluorimetry, ore crushers, magnetic separation of iron, batteries and railway signaling devices< During the first World War, he developed torpedo mechanism, flamethrower and underwater periscope< On October 21, 1929, on the 50th anniversary of the invention of the electric light, people held a grand celebration for Edison. Albert Einstein of the Federal Republic of Germany and Madame Curie of the French Republic congratulated him one after another. Unfortunately, at this celebration, when Edison delivered his reply, he suddenly fainted e to excessive excitement. From then on, his health went from bad to worse. On October 18, 1931, the scientist who had made great contributions to mankind died of illness at the age of 84
Edison's ecation level is very low, but his contribution to mankind is so great. What's the "secret" here? In addition to a curious heart, he has an instinct to test himself, that is, he has the infinite energy and bold spirit of extraordinary hard work. When someone called Edison a "genius", he explained: "genius is two percent inspiration and ninety-eight percent perspiration." In the "invention factory", he organized many people of different professions, including more than 100 scientists, engineers, technicians and workers. Many of Edison's major inventions were successful thanks to this collective force. His achievements are mainly e to his hard work and creative ability as well as the collective strength. In addition, his wife also played a very important role<
chronology of Edison's invention and creation:
he invented the "voting counter" on October 11, 1868 and won the first patent right in his life< In October 1869, we established "pop Edison Company" with friends
in 1870, he invented the general printing press, granted the patent right, and obtained $40000. We set up our own manufacturing plant in New York< From 1872 to 1876, he invented the electric animation mechanical and electrical telegraph, automatic repeating telegraph method, double and quadruple telegraph method, and made wax paper carbon resistor< In 1875, the acoustic analysis resonator was invented< In 1876, the first instrial research laboratory was established in Monroe Park, New Jersey. It is the origination of the concept of modern "research group". Invention of carbon rod transmitter. Patent application for automatic telegraph recorder< In 1877, the telephone invented by Bell was improved in Monroe Park and put into practical use. Obtained three patents: perforated pen, pneumatic iron pen and ordinary iron pen. On August 20, he invented the phonograph, which proved to be Edison's favorite project< In 1878, Edison claimed to solve the problem of electric lighting. The Royal Society of England held a phonograph exhibition. Improved gramophone, design microphone, loudspeaker, sound engine, tuning engine, microcalorimeter, taste meter, etc. On February 19, it won the patent of phonograph. In July, he went to Wyoming with Professor pike of the University of Pennsylvania to observe the total solar eclipse, and measured the temperature of the whole body around the sun with his thermometer. In August, he returned to Monroe Park and re invested in scientific research and experiment. Britain approved Edison's patent application for "VCR". William Wallace, who visited Connecticut in September. He began to study the invention of the electric lamp. A patent application for platinum wire "electric lamp" was filed on October 5
1879-1880
one day, he pointed to the hen that was hatching and asked his mother, "what's the hen doing sitting under her ass?" Mother said, "Oh, it's hatching chickens!" In the afternoon, Edison disappeared suddenly. The family searched around anxiously and finally found him in the chicken coop. It turned out that he was squatting in the henhouse, buttocks down a lot of eggs to hatch chickens! After seeing it, his parents couldn't help laughing and crying, so they had to pull him out to wash his face and clothes. Another time, he saw birds flying freely in the sky and thought: since birds can fly, why can't people fly? So, he found a kind of powder for his little friend to eat, in order to let him fly to the sky. As a result, his partner almost died, and Edison was beaten up by his father<
after a long time, Eddie grew up to 8 years old, and his parents sent him to a rural primary school, thinking that he would go to school safely from now on. Who knows, he is still inquisitive, often ask the teacher mbfounded, embarrassed. Once in an arithmetic class, the teacher wrote "2 + 2 = 4" on the blackboard. Edison immediately stood up and asked, "teacher, why is 2 plus 2 equal to 4?" This question stopped the teacher. He thought Edison was a troublemaker. He made trouble with the teacher. So after three months of class, Edison was driven home by the teacher
Edison's mother was a great mother. Instead of blaming her only son for being turned back, she decided to ecate him well. When she found that Edison was curious and particularly interested in physics and chemistry, she bought him books on physics and chemistry experiments. Edison did his own experiment according to his books. It can be said that this is the enlightenment ecation of Edison's scientific invention
Edison, who grew up, learned radio receiving and transmitting technology. He got a night job as a telegraph operator at the Stratford railway station. According to the regulations, the night shift operator must send a signal to the vehicle service director every hour after 9 p.m., no matter what happened. In order to have a good night's rest and to be able to study and invent ring the day, Edison designed a telegraph to automatically send signals on time. This is the prototype of the telegraph< Before long, he improved the telegraph. After many tests, a new transmitter was successfully trial proced. Edison looked at the machine he had invented and laughed happily< It should be said that every invention of Edison is closely related to his curiosity. After he invented the telegraph, he started experimenting with the telephone. He found that the diaphragm in the microphone could vibrate with the voice, so he observed it carefully and made a detailed record in his notebook. Thus, a "talking machine" was made. When people heard the news, they all came to watch and called him "the greatest inventor". Therefore, curiosity is a prerequisite for one's success and wisdom.
Edison was curious about many things since he was a child, and liked to experiment with them himself until he understood the truth. When he grew up, he devoted himself to research and invention according to his own interests. He set up a laboratory in New Jersey and invented more than 2000 kinds of things in his life, such as electric lamp, telegraph, phonograph, video camera, magnetic separator, crusher and so on. Edison's strong research spirit made him make great contribution to the improvement of human life style
(0) he started his first experiment in his own wooden shed, Edison
Edison liked to think about a series of problems with his unique big head when he was young. When he saw the blacksmith burning the iron red in the raging fire and hammering it into various tools, he shook his head and asked one question after another: what is fire? Why does fire burn? Why is the fire so hot? Why does iron turn red after it is burned in the fire? Why is iron red soft? Back home, little Edison started his first experiment in his wooden shed. He took the hay and lit it. He wanted to find out what the fire was. However, little Edison's first experiment led to a fire, burning down the wooden shed at home
(1) "life is too short. Think more and do more with less time."
"waste, the biggest waste is to waste time." Edison often said to his assistant“ Life is too short. Think more and do more with less time. "
one day, Edison was working in the laboratory. He handed his assistant an empty pear shaped glass bulb without a light port and said, "you measure the capacity of the bulb." He bowed his head to work again
after a long time, he asked, "what's the capacity?" He didn't hear the answer. He turned his head and saw his assistant measuring the perimeter and inclination of the bulb with a tape measure. He took the measured number and put it on the table to calculate. Because the bulb is pear shaped, it is not a regular status quo. Therefore, it is very difficult to calculate the perimeter and inclination of the bulb. He said, "time, time, how do you spend so much time?" Edison came over, picked up the empty light bulb, filled it with water, handed it to his assistant, and said, "pour the water in the measuring glass, and tell me its capacity right away."
the assistant immediately read out the number
Edison said, "what an easy way to measure. It's accurate and time-saving. Why can't you think of it? Is it not a waste of time? "
the assistant blushed
Edison murmured: "life is too short, too short. Save time and do more things!"< (2) everyone here already knows me
Edison was a poor worker before he became famous. Once, his old friend met him in the street and said with concern, "look, this overcoat on you is not in good condition. You should replace it with a new one."
"do you need it? No one knows me in New York Edison answered with indifference
a few years later, Eddie has become a great inventor< One day, Edison met his friend on the street of New York“ "Oh," exclaimed the friend, "Why are you still wearing this old coat? This time, you need a new one anyway
"do you need it? Everyone here already knows me. " Edison still answered with indifference
(3) Mom, I'm going to make a night's sun
one snowy night, Edison's mom suddenly fell ill, and dad rushed to the doctor. The doctor said, "your mother has acute appendicitis and needs an operation.". At that time, there was only oil lamp, but no electric lamp. The light of the oil lamp was very dark, and it would be wrong if you were not careful. Edison suddenly thought of a good way, he took out all the oil lamps at home, and then put a mirror behind the oil lamp to let the doctor finish the operation smoothly. The doctor said, "son, you saved your mother with your wisdom and cleverness." Edison took his mother's hand and said, "Mom, I want to make a night's sun."< Reference: Edison's mother once suffered from appendicitis. As his family was poor, his mother asked the doctor to operate at home. The doctor agreed, but the light in the room was too dim for the doctor to see clearly. Edison had an idea. He gathered the light through the reflection of the mirror, and the room lit up immediately, and his mother was saved
(4) even sleeping is absorbing the nutrition in the book
Edison, in order to carry out experiments, often does not go out of the laboratory for several days, does not sleep. I was so tired that I took a nap on the experimental table with a book as a pillow. One day, his friend joked with him: "no wonder Edison knows so many inventions. It turns out that he even sleeps to absorb the nutrition in the book."
(5) why can't I when hens can hatch chickens?
once, when it was time to eat, Edison still didn't come back. His parents were very anxious and looked around for him. They didn't find him in the grass shed by the yard until the evening. Father saw him lying motionless in the grass with a lot of eggs, so he asked strangely, "what are you doing?" Little Edison answered calmly, "I'm hatching chickens." It turned out that when he saw that hens would hatch chickens, he felt very strange and always wanted to try it on his own. At that time, his father pulled him up and told him that people can't hatch chickens. On the way home, he was still puzzled and asked, "why can't I, when hens can hatch chickens?"< (6) what's the secret in the beehive?
Edison was always in danger because he was interested in many things. Once, he went to the house where the wheat was stored and accidentally fell into the wheat store. The wheat buried his head and could not move. He nearly died. Fortunately, he was caught by Edison's foot and pulled out in time. Another time, he fell into the water and was pulled up like a drowned chicken. He himself was shocked. When he was 4 years old, he wanted to see what was in the wild beehive on the fence, so he poked it with a branch. His face was stung by a wild bee, and he could hardly open his eyes<
Edison's anecdotes are published by celebrity.com www.mingren.biz Most of the content is collected on the Internet, and the right belongs to the original author http://www.mr699.cn/story/html/62495.html Thomas Alva Edison is a world-famous American electrician and inventor Besides telephone, telegraph, film and other inventions and contributions, there are also many famous creations and insights in mining, construction, chemical and other fields.

after a long time, he asked, "what's the capacity?" He didn't hear the answer. He turned his head and saw his assistant measuring the perimeter and inclination of the bulb with a tape measure. He took the measured number and put it on the table to calculate. He said, "time, time, how do you spend so much time?" Edison came over, picked up the empty light bulb, filled it with water, handed it to his assistant, and said, "pour the water in the measuring glass, and tell me its capacity right away."
the assistant immediately read out the number
Edison said, "what an easy way to measure. It's accurate and time-saving. Why can't you think of it? Is it not a waste of time? "
the assistant blushed
Edison murmured: "life is too short, too short. Save time and do more things!"< Before he became famous, Edison was a poor worker. Once, his old friend met him in the street and said with concern, "look, this overcoat on you is not in good condition. You should replace it with a new one."
"do you need it? No one knows me in New York Edison answered with indifference
a few years later, Eddie has become a great inventor< One day, Edison met his friend on the street of New York“ "Oh," exclaimed the friend, "Why are you still wearing this old coat? This time, you need a new one anyway
"do you need it? Everyone here already knows me. " Edison still answered with indifference<
Story 2:
Thomas Edison was born in 1847 in Warsaw, USA. He only went to primary school for three months. The school teacher said he was "stupid", so did his relatives and friends. But his mother didn't believe it. She was his teacher and guided him to read some books. Before he was 12 years old, he had read many difficult books. His father also led him to study Newton's principle. Family ecation and influence, so that he developed a spirit of diligence and amazing perseverance
Edison loved science. When he was very young, he stored hundreds of bottles for various experiments in his cellar and built a small laboratory. He spent all the money he saved on chemical supplies and instruments. But this money alone can not meet the needs of the experiment, so he went to the train as a newsboy. He gets on the bus every morning and goes home after nine o'clock in the evening. After the experiment, he often takes a rest late at night. Later, he found that there was a smoking room in the luggage compartment of the train that was not used, so he moved the experimental materials from the cellar of his home to this room and insisted on doing chemical experiments. Here, he also learned to use a printer set up here, and was able to record local news with telegraph numbers, and ran a newspaper. The newspaper was so popular that it sold well that he was only twelve years old. One day, the train shakes, the luggage slides down, and one of his phosphorus poles falls to the ground, and the carriage catches fire immediately. The fire was put out by the people who rushed to the scene, but the conctor deafened him and disabled him for life. The conctor also kicked everything from his "four wheel lab" and "travel printing room" under the car< The difficulties and setbacks did not affect Edison's determination to carry out scientific experiments, so he built a laboratory at home. It is common in experiments that clothes are beaten and burned by electricity. Once, his face was burnt out by nitric acid. Even so, he never lost heart. Edison's earliest efforts greatly contributed to his later inventions. However, like other great inventors, Edison's road was not smooth. He worked as a night telegraph student. Spend a lot of energy in bookstores and libraries. But because of several times of unemployment, finally had to go to New York to join friends
Edison came to New York after a lot of hardships. At this time, he didn't even have a penny in his pocket. He was so hungry that he had to ask for some tea, which was his first meal in New York. Here, he found a friend for a long time, but his friend is also unemployed. The hungry Edison was looked down upon for his poor appearance and ragged clothes. Later, he was allowed to stay overnight in a battery room. It happened that a communication machine was set up in the room to release the market price. On the morning of the third day when he arrived, the machine broke down. Because he was careful and studied, he helped others repair the machine quickly and was left behind, so he found a job. Since then, he has made great efforts to cooperate with others to reform the market price communication machine. Soon, he opened a small factory to proce this kind of communication machine, and graally embarked on the road of scientific research<
Story 3:
Einstein story
childhood
Albert, the greatest physicist of the 20th century; Albert Einstein was born in Ulm, southwest Germany, on March 14, 1879. A year later, he moved to Munich with his family. Einstein's parents were Jewish, and his father was Herman; Einstein and his uncle Jacob; Einstein co founded an electrical factory that proces motors, arc lamps and electrical instruments for power stations and lighting systems. His mother, boleen, was a housewife with secondary ecation. She loved music very much and taught Einstein to play violin when he was six years old
Einstein was not lively when he was a child, and he could not speak when he was more than three years old. His parents worried that he was mb, so they took him to the doctor for examination. Fortunately, Little Einstein was not mb, but he didn't speak very well until he was nine years old. Every word he said had to be thought hard but seriously< When Einstein was four or five years old, his father gave him a compass. When he found that the compass always pointed in a fixed direction, he was very surprised. He felt that something must be deeply hidden behind this phenomenon. He played the compass happily for several days, and pestered his father and uncle Jacob with a series of questions. Although he can't even say the word "magnetism", he stubbornly wants to know why the compass can guide. This kind of deep and lasting impression can be vividly recalled by Einstein until he was 67 years old
when Einstein was in primary and secondary school, his lessons were ordinary. Because of his slow behavior, he doesn't like to communicate with others, so his teachers and classmates don't like him. The teacher who taught him Greek and Latin was even more disgusted with him. He once publicly scolded him: "Einstein, you won't be a success when you grow up." And because he was afraid that he would affect other students in class, he wanted to drive him out of school< Einstein's uncle Jacob was in charge of technical affairs in the electrical factory, while Einstein's father was in charge of business. Jacob is an engineer. He loves mathematics very much. When Little Einstein comes to him to ask questions, he always introces mathematics knowledge to him in very simple and popular language. Under the influence of his uncle, Einstein was early enlightened by science and philosophy
my father's business is not good, but he is an optimistic and kind-hearted man. One night a week, the family invites poor students to Munich for dinner, which is tantamount to helping them. One of them is a pair of Jewish brothers, Max and Bernard, from Lithuania. They are both medical students. They like reading books and have a wide range of interests. They were invited to eat at Einstein's house and made good friends with the shy little Einstein with black hair and brown eyes
Max can be said to be Einstein's "first teacher". He borrowed some popular natural science books to show him. When Einstein was 12 years old, Max gave him a textbook of plane geometry. When Einstein recalled this sacred little book in his later years, he said: "there are many assertions in this book, for example, the intersection of the three heights of the triangle. Although they are not obvious, they can be proved so reliably that no doubt seems possible. This clarity and reliability left an indescribable impression on me. "
Einstein was also lucky to know the main achievements and methods in the field of natural science from an excellent popular book. Popular science books not only enhanced Einstein's knowledge, but also aroused young people's curiosity and caused him to think deeply about the problems< When Einstein was 16 years old, he applied for the Engineering Department of the Federal Polytechnic University in Zurich, Switzerland, but he failed in the entrance examination. He accepted the proposal of the president of the Federal University of technology and Professor Weber, a famous physicist of the University, to complete the secondary school course in the state middle school of arau, Switzerland, in order to obtain a secondary school degree< In October 1896, Einstein entered Zurich University of technology to study mathematics and physics in the normal department. He is disgusted with the school's injection ecation, and thinks that it makes people have no time or interest to think about other problems. Fortunately, there is much less compulsory ecation at the Federal Polytechnic University in Zurich than at any other university that stifles the real power of science. Einstein made full use of the free air in the school and focused on the subjects he loved. In school, he extensively read the works of Helmholtz, Hertz and other physics masters, and he was most fascinated by Maxwell's electromagnetic theory. He has the ability of self-study, the habit of analyzing problems and the ability of independent thinking.
