7 famous inventions were initially badly criticized

The aircraft used to be a scientific toy, the original telephone invention was also considered a children's toy . but today is an indispensable thing in human life.

Pioneers always do different things, this is always true in scientific innovation. Because it is so new and contrary to social habits, many inventors have to go through a period of challenging public opinion to be recognized for value.

Light bulb

The great inventor Edison and the historic light bulb.

In 1878, the genius inventor (1847-1931) began studying filament bulbs but few people were interested.

They think that light is contrary to nature. Many people have filament lamps like ghostly light spots and can only be used in fairy tales.

A member of the US Parliament said: "Edison's light bulb is only useful on the other side of the Atlantic Ocean, not the United States."

Over time, people also have to acknowledge the values ​​that light bulbs bring. So far electric light bulbs have become indispensable things in human life.

Alternating current

Tesla's alternating current has been criticized for being lethal.

Edison was the creator of a filament light bulb, and was a supporter of direct current. But this scientist is also an objection to the use of alternating current by scientists (1856-1943), although the efficiency of new electric current is much better.

Edision once said: "Encouraging the use of alternating current only wastes time. Nobody will use it."

There was even an experiment to prove that alternating current could be lethal to counteract the development of this new trend.

However, only a few years later, alternating current was won. And today, AC electricity is used in all areas of modern life.

Planes

The Wright brothers' short 12-second flight.

It was considered the inventor of the aircraft when in 1903 made a 12-second historic flight.

At the time of birth, the aircraft met many criticisms. In 1911, Ferdinand Foch (1851-1929), a general of the French squadron in the First World War, said that the aircraft was just a fascinating scientific toy, not meant for the military.

But since World War II, airplanes have become a powerful weapon in the military and an indispensable means of transportation.

Phone

Bell's phone invention turned out to be considered a baby toy.

The phone is attached to the Scottish scientist (1847-1922).

At the age of 16, he began his first studies on the mechanism of sound propagation. By 1876, Alexander Graham Bell was granted a patent for his phone and was named the father of the media.

But when he was about to sell his invention to American media company Western Union for $ 100,000, the company's board of directors did not approve and said his device had obvious limitations and nothing more. a toy for children.

Without stopping, Bell set up a phone company in 1877. Less than a decade later, about 150,000 people used phones across the United States.

Television

John Logie Baird, who laid the foundations for the television industry.

On March 25, 1925, Scottish inventor John Logie Baird (1888-1946) first performed a mobile television in London with a talking and moving mannequin.

In January 1926, Baird proved to be able to transmit moving images through radio waves. By 1928, it was possible to broadcast and receive transatlantic television waves - between London and New York.

Lee De Forest had many criticisms with new inventions.

However, the television was born with many criticisms. Lee De Forest, who is often regarded as the father of radio, said television was an invention that could not be realized and could not be used commercially because of the expensive cost."People can only have television in dreams," Lee De Forest said.

Even 20 years later, film producer Darryl Zanuck still doubts that "People will soon get tired of staring at the television screen every night."

Spaceship

In the 20th century, the Soviet Union was a leader in the space industry.

In the 20th century, typical Russian scientists, Konstantin Tsiolkovsky tried to find ways for people to explore space with rockets.

However, in the 1920s, Lee De Forest said: "I guarantee that such human flights will never materialize no matter how much science progresses."

The New York Times also concluded similarly: "The missile will not be able to leave the Earth's atmosphere."

But in 1961, astronaut Yuri Gagarin became the first person to fly into space, and in 1969, Apollo 11 landed on the Moon successfully.

Umbrella (box)

Even though the road was heavily criticized in the UK.

Not an inventor, but a part of British life. At that time, people thought that although it was a symbol of weakness and heavy French culture - which was a rival of England.

In the middle of the 18th century, the British often criticized those who used parachutes on the road. Jonas Hanway ignored the public opinion, still walking with the umbrella in his hand. People stay away from him, calling him a dangerous "monster".

Over time, the British became accustomed to the image of umbrellas on the street and used extensively to cover the rain and sun. Even though it is considered as a fashion accessory of many women on the road.

And no one feels weak even when Jonas Hanway is brave for years against the criticism of the people around him and has won.
