1. In 1940, Walter Irken of the United States built the first new type of computer, named "Mark 1". The computer was huge, made a lot of noise when operating, and could only handle two additional problems per second, but it was still the first computer.
(2). Generally speaking, the world’s first computer was designed and developed in 1945 by two professors from the University of Pennsylvania, Mauchly and Eckert, and its English name was ENIAC. (Eniac), is actually an electronic literacy computer. However, before that, people had been studying computers for a long time.
2. In 1769, Frenchman N.J. Cugnot built the world's first steam-driven three-wheeled car. But people generally regard 1886 as the first year of the automobile, and some scholars regard 1885, the year when Carl Benz made the first three-wheeled automobile, as the birth year of the automobile. Benz and Daimler are regarded as the originators of the automobile industry.
3. The first machine that can truly be called a computer was born in the United States in 1946. It was invented by Mao Qili and Eckert, and its name was ENIAC. This computer used vacuum tubes to process signals, so it was bulky (it took up a whole room), consumed a lot of power (everyone in the town knew about it because the lights in every house were dimmed when it was in use!), and had very low memory capacity. (Only more than 100 words), but it is already a major progress in human science and technology. We usually refer to computers that use vacuum tubes as the first generation computers.
4. "Watson, come and help me!" This was a distress call made by Alexander Graham Bell, the famous inventor of the telephone, to his assistant in 1876. March 10th. As the first recorded telephone call, it changed the world.
He applied for a telephone patent at the U.S. Patent Office on February 14, 1876. In fact, just two hours after he filed his application, a man named E. Gray also applied for a telephone patent.
5. In 1924, the British Baird invented the most primitive television, which transmitted images using electricity.
American RCA launched the world's first black-and-white television in 1939, set the national color television standard in 1953, and launched RCA color television in 1954. Best answer
19th century:
In 1888, Dunlop, an Irish veterinarian, was inspired by treating gastric bloating in cattle and glued the rubber hose used for watering in his garden into a Round and fully inflated, this was the beginning of pneumatic tires. Pneumatic tires are an epoch-making initiative in the history of bicycle development. They not only fundamentally change the riding performance of bicycles, but also improve the use functions of bicycles. From 1791 to 1888, the invention and improvement of the bicycle, the ancestor of the motorcycle, went through the unremitting efforts of these inventors for nearly 100 years. We can't help but be moved by human inventions and creations.
In 1886, the British mechanical engineer Staley designed a new bicycle style from the perspective of mechanics and kinematics. He installed a front fork and a brake, and the front and rear wheels were the same size to maintain balance. A diamond-shaped frame was made of steel tubes, and rubber wheels were used for the first time. Staley not only improved the structure of bicycles, but also modified many machine tools for the production of bicycle parts, opening up a broad path for the mass production and popularization of bicycles. Therefore, he is called the "Father of Bicycles" by future generations. The bicycle models he designed are basically the same as today's bicycles.
In 1845, the German von Martens invented the world's first rotating machine that could pan 150°. In 1849, David Brewster invented the stereo camera and the two-lens stereoscope. In 1861, physicist Maxwell invented the world's first color photograph.
The Egyptians were the first to use umbrellas. As early as 1200 BC, Egyptian nobles often asked slaves to hold parasols for them when traveling. The Romans used umbrellas to protect themselves from the sun in the Mediterranean region. In China, the umbrella was invented by Lu Ban's wife in 1000 BC. The umbrella is called a "movable house".
As early as 1831, the British scientist Faraday discovered the phenomenon of electromagnetic induction and proposed the theoretical basis of the generator. Based on this discovery, scientists have conducted in-depth exploration and research on electricity since the 1860s and 1870s, and a series of electrical inventions have emerged. In 1866, the German Siemens made a generator. In the 1870s, practical electric generators became available.
In 1882, Frenchman Depreux discovered a method of transmitting electricity over long distances, and American scientist Edison built the first thermal power station in the United States and connected transmission lines into a network. Electricity is an excellent and cheap new energy source. Its wide application has promoted the rapid development of a series of emerging industries such as the power industry and electrical appliance manufacturing industry. Human history has entered the "electrical age" from the "steam age".
In 1876, Bell, a Scotsman who settled in Boston, USA, successfully tried to make a telephone call. Edison and others made important improvements based on Bell's invention, making telephone communication very popular in many countries around the world. In 1877, the first telephone exchange was built in the United States.
In 1888, German scientist Hertz discovered electromagnetic waves. Using this electromagnetic wave, Italian Marconi made radio communication equipment. In 1899, Marconi successfully sent a message between Britain and France; in 1901, he successfully sent a message across the Atlantic. The development of modern telecommunications has provided convenience for the rapid transmission of information. Since then, economic, political and cultural ties around the world have been further strengthened.
In the mid-1980s, German inventors Daimler and Karl Benz proposed the design of a light internal combustion engine that uses gasoline as fuel. In the 1990s, German engineer Diesel designed a more efficient internal combustion engine, also known as a diesel engine, because it could use diesel as fuel. The invention of the internal combustion engine, on the one hand, solved the engine problem of transportation and caused revolutionary changes in the field of transportation. In the late 19th century, a new form of transportation - the automobile - appeared. In the 1980s, German Karl Benz successfully built the first car powered by a gasoline internal combustion engine. In 1896, American Henry Ford built his first four-wheeled car. At the same time, many countries began to establish automobile industries.
In 1903, the aircraft manufactured by the Americans, the Wright Brothers, successfully made a test flight, realizing mankind's dream of flying into the sky and heralding the arrival of a new era of transportation.
20th Century:
Laser Technology: Expanding New Fields of Scientific Research
In 1960, Maiman successfully developed the world's first practical ruby ??laser. It marked the birth of laser technology.
In recent years, laser technology has developed at an alarming rate, and the scope of applications has continued to expand, such as laser preservation, laser breeding, laser medical treatment, laser beauty, etc., which have become popular areas of research among scientific and technological personnel.
In the past, people were still struggling to keep vegetables fresh at room temperature, but now lasers have easily solved this problem. For example, when vegetables are transported over long distances, it is enough to scan them once with a laser before shipment, and they will still be fresh for ten or eight days during the journey. The principle is very simple. When the laser energy is high, it inhibits the growth of vegetables. On the contrary, if its energy is suitable for its growth conditions, it can be produced, so laser breeding has been promoted again. Irradiating seeds with laser can cause changes in crop traits and increase crop yields.
Cars: Carrying the Times forward
Cars have changed the entire transportation situation of mankind, and owning the automobile industry has become a symbol of every powerful industrial country.
The automobile has gone through such a history: in 1771, the Frenchman Guineau designed a steam engine tricycle; in 1860, the French Renault manufactured a car engine fueled by coal gas; in 1885, the German Ford and Daimler each completed a locomotive equipped with a high-speed gasoline engine and a three-wheeled vehicle equipped with a two-stroke gasoline engine, and successfully commercialized them; in 1908, the American Ford used a flow-type production line to mass-produce low-price, high-safety, A fast Model T car. The popularization of automobiles began; in 1912, Cadillac launched an electronic ignition starter, which made women fall in love with automobiles; in 1926, Daimler-Benz, the world's first automobile manufacturing company, was established; in 1934, the A front-wheel drive car was launched; in 1940, the war caused many car manufacturers to cease production, and European car manufacturers began to turn to the production of military vehicles; in the 1950s, Germany's Volvo's shell sedan became the most popular car once it was launched; in 1970 In 2000, Japanese cars became popular in Asia. Toyota, Honda, Mitsubishi and Nissan's ultra-high-tech small cars invaded the European and American markets, rewriting the monopoly situation of European and American brands.
In fact, the invention of the automobile has greatly improved human mobility, broadened human horizons and pursued freedom in the 20th century.
Mobile phones: the dream of wireless communication
Humanity’s dream of wireless communication was realized in 1973 in New York, USA. At that time, the world's first practical mobile phone was large in size and weighed 1.9 kilograms. It was a veritable "big brother". Today, 26 years later, the world's smallest mobile phone was born. It was only as big as a pager and much lighter than the first generation mobile phone.
Satellite broadcasting: zero-distance media transmission
1964 was another important turning point in the history of human communication. In the summer of this year, thousands of viewers around the world watched TV for the first time. Watch the live satellite broadcast of the Tokyo Olympics in Japan. This is the first time in human history that people can watch events thousands of miles away at the same time through TV screens. In addition to sighing at the wonderful and spectacular opening ceremony and various competitions of the Olympic Games, people are also amazed at the progress of science and technology. This is all thanks to the geostationary satellite invented by Harold Rosen.
Internet: Another way of communicating emotions
In the summer of 1969, the prototype of the Internet appeared in the United States. It consisted of four computer websites, one at the University of California, the other Three are in Nevada. In 1972, experimenters sent the first email on the experimental network for the first time, which marked the beginning of the integration of the international Internet with communications. In the 1990s, the international Internet began to be used for commercial purposes. In 1995, the development of the Internet reached its first climax, and this year was called the International Year of the Internet. Driven by the wave of electronic commerce, the impact of the international Internet on human society will be even more profound in the 21st century.
