Who is the inventor of the canvas red envelope, the ancient Chinese invention and inventor

It can't be called an invention, but an improver, and that should be the Yin Chen family.

The red envelopes of the Yin Chen family are the first enterprises to use canvas as the fabric, with relatively novel styles and unique creativity.

In 1769, the French army engineer Gounod built the first automobile powered by a steam engine.

In 1796, the Italian scientist Walz invented the world's first storage battery, which brought a historic turning point to the birth and development of the automobile.

On January 29, 1886, the Mannheim Patent Office granted Carl Benz a patent for his three-wheeled car developed in 1885, a date that is known to most as the birth of the modern automobile.

German Godlip Daimler made the world's first four-wheeled car.

Explanation:

It is now widely accepted that the automobile was invented by Carl Benz for two reasons:

First, the prototype of the car made at that time, in addition to only three wheels, single-cylinder four-stroke gasoline engine, electric ignition, carburetor and other original technologies, in one fell swoop set the tone of automobile design, even the current car can not jump out of this box;

Second, Carl Benz applied for a patent at the same time, which was a wise decision that not only earned him the reputation of the "father of the automobile", but also ensured that he would have no worries about food and clothing for the rest of his life.

It was invented by the old man Mercedes-Benz.

Inventor Johann von Neumann.

Computer (computer), commonly known as computer, is an electronic computer used for high-speed calculation, which can perform numerical calculations, logical calculations, and also has the function of storage and memory. It is a modern intelligent electronic device that can operate according to the program and process massive amounts of data automatically and at high speed. A computer that consists of a hardware system and a software system without any software installed is called bare metal.

It can be divided into five categories: supercomputers, industrial control computers, network computers, personal computers, and embedded computers, and the more advanced computers include biological computers, photonic computers, quantum computers, etc.

Inventor of the computer John von Neumann. The computer is one of the most advanced scientific and technological inventions of the 20th century, which has had an extremely important impact on human production and social activities, and has developed rapidly with strong vitality. Its application field has expanded from the initial military scientific research application to all fields of society, and has formed a huge computer industry, which has led to technological progress on a global scale, which has triggered profound social changes, and computers have spread all over ordinary schools, enterprises, and institutions, and have entered the homes of ordinary people, becoming an indispensable tool in the information society.

In the early days, the PC machine was called a microcomputer, and it was called a computer among Hong Kong businessmen in the early days, and later it was introduced into China and became the most familiar name to the public. The scientific name of the computer is the electronic computer, which was developed from the early electric calculator. In 1946, the world's first electronic digital computer "ENIAC" appeared for calculating ballistics.

It is manufactured by the Moore Institute of Electrical Engineering of the University of Pennsylvania in the United States, but it is huge, covering an area of more than 170 square meters, weighing about 30 tons, and consuming nearly 100 kilowatts of electricity. Obviously, such a computer costs a lot and is inconvenient to use. In 1956, the transistor electronic computer was born, which was the second generation of electronic computers.

It can be accommodated in just a few larger cabinets, and the calculation speed is greatly improved. In 1959, the third generation of integrated circuit computers appeared. The original computer was invented by Johann von Neumann (at that time the computing power of the computer was equivalent to today's calculator), the size of three warehouses, and gradually developed.

It was the American mathematician von Neumann.

The first machine that can really be called a computer was born in the United States in 1946, invented by Mao Qili and Eckert, and the name is ENIAC

Hello, what you want to ask is who invented the concept of "time", right? This is difficult to verify, according to the current archaeological discoveries, primitive society when the ancient human beings already had the habit of knotting ropes, that is to say, when human intelligence began to enlighten, there was a concept of time, sunrise and sunset, spring to autumn, human beings from the beginning of the fire to get used to and master the law of work and rest, it can be said that there was the idea of time at that time, and then there was the term time. As far as China is concerned, the 24 solar terms produced during the period of the Three Emperors and Five Emperors are said to have a precise distinction between the ancients and the ability to engage in agriculture through the grasp of time.

If you want to ask about the profound concept of time, you have to mention "space", the first to distinguish between time and space was Einstein, he proposed the flow theory of time, under the macroscopic concept of cosmic space and time, to prove the origin and end of the universe galaxy. The contemporary master is Steve Hawking, who went one step further in Einstein's theory and deduced the end of the universe by proving the existence of black holes, thus deducing the end of time.

The Wright brothers were only Orville and Wilbur.

Ancient Egyptians and ancient Americans, and possibly ancient Chinese.

While America's aerospace celebrities were busy celebrating the 100th anniversary of the Wright brothers' successful test flight of the first powered vehicle, Brazilians believe that Alberto Santos Dumont is the true father of powered flight.

Brothers Wilbur Wright and Orville Wright successfully lifted the first powered vehicle, Aviator I, into the air for 12 seconds in Kitty Hawk, North Carolina, on December 17, 1903. But supporters of Santos Dumont saw their hero's flight in a Paris park on October 23, 1906, as a real first.

Santos Dumont was born in Brazil, the son of a French jeweler. At the age of 18 he returned.

He arrived in his native France and quickly became obsessed with flying. After a few years of dealing with hot air balloons, Santos Dumont turned his attention to the powered flight of airplanes. On October 23, 1906, under the admiring gaze of a crowd of spectators, Santos Dumont began his first flight in the "Double 14" biplane in the Parc de la Bagatale in the western suburbs of Paris.

The flight had a distance of 60 meters and a ground clearance of about 2 meters. The skeleton of the Double 14 is made of aluminum and bamboo, covered with silk, and the gasoline engine of the aircraft was designed and built by Santos Dumont. The Wright brothers' first flight was done at Kitty Hawk Beach, where the plane was able to take off with the help of a ramp and only a handful of people**.

On November 21 of the same year, Santos Dumont took off again in the "Double 14". This time he flew 6 meters at an altitude of 220 meters. Country.

The International Aviation Federation registered these two flights as the earliest aviation records.

Later, Santos Dumont built a new airplane called the Dragonfly, but the work left him exhausted and exhausted. He returned to Brazil in 1909. Santos Dumont had always hoped that airplanes could be used as a means of transportation, but it was not as he had imagined.

During World War I, airplanes were used to drop bombs for the first time, a move that exacerbated his feelings of loss. He committed suicide on July 23, 1932, shortly after learning that airplanes were being used to suppress an armed uprising in Brazil, at the age of 59.

To this day, Santos Dumont is here.

Brazil still enjoys a high reputation. The Brazilian Air Force officially recognized him as the first person to complete a flight on his own. One of Rio de Janeiro's two civil airports is also named after him.

In fact, Santos Dumont is not the only one challenging the Wright brothers. The Frenchman Clement Adair claimed that on October 9, 1890, he flew about 48 meters in a steam-powered plane over his friend's estate on the outskirts of Paris.

In France, many people call him the "father of French aviation".

Richard Pearce, a strange New Zealand farmer, also climbed into his homemade monoplane on March 31, 1903. According to his own account, his plane also flew about 140 meters before diving headlong into his own fence.

The Wright Brothers.

In 1903, the Wright brothers of the United States designed and built an airplane to successfully fly, which was the world's first powered, maneuverable flight of a heavier-than-air aircraft.

Of course: Ma Jialin.

In 1567, the aircraft designed and manufactured by Ma Jialin of China made a successful flight, which was the world's first powered, maneuverable flight of a heavier-than-air aircraft. Zhu Yanjun.

There's the answer here, hehe
