9 ideas that were once considered fantasies have now become a reality

The ideas below have been considered impracticable in the past, but thanks to the advances in science and technology, they have now become a reality.

In 1969, Neil Armstrong and Buzz Aldrin set foot on the moon, marking "a small step for a man, but a leap for humanity". And, that small step is also the beginning of a series of "moonshot" ideas of people gradually becoming a reality thanks to the advances of science and technology.

The idea of ​​a moonshot is as unreal as an attempt to go to the moon a hundred years ago.

The concept of "moonshot ideas " can be understood as ideas that people thought were impracticable, expensive, easy to fail, but if they succeed, it will mark a big breakthrough for science and technology. of mankind (like launching a spacecraft to the moon in the past). And in fact, if we pay attention, many of the great inventions or achievements of science and technology of mankind started with such unrealistic ideas.

And below, let us take a look at ideas that were once considered unrealistic, but now come true.

The floating city doesn't have humanity, but the floating houses the Netherlands has

About 13 centuries ago, Homer (author of the epic Iliad and Odyssey) imagined a floating city sheltered by impregnable copper walls. Until now, the floating city has not yet become a reality, but mankind has created buildings that can float above the water, which we can see in the Netherlands as shown in the picture below:

Floating houses in the Netherlands.

These floating houses are not afraid of flooding, because the rising water, they will also emerge. Such works have become the premise for the United Nations to think of the idea of ​​a floating city, to deal with issues such as rising sea levels or increasingly limited residential land.

Astronaut was once unthinkable, what about now? Astronauts have been in space for months

Astronaut is no longer a myth.

American inventor Lee de Forest once predicted that space travel was an almost impossible task. In an interview with Voice of America in 1957, he once said: "Humans are originally just earthly creatures, so only the imagination of science can turn them into travelers. on the planet. "

But, less than 50 years later, the International Space Station has become a place for astronauts to live, thereby proving that: humans can completely live in outer space.

Self-driving cars have now begun to serve people

In fact, self-driving cars have been the goal of many carmakers' research since the 20s of the last century, but it has not been until 5 years in the past.

Just a year ago, self-driving car company Waymo brought a whole fleet of self-driving taxis into operation in Arizona, USA. These cars will be dispatched to customers via a ride-hailing app. By May this year, after half a year of operation, Waymo's self-driving cars had served more than 1,000 customers.

A subsidiary of Alphabet has covered the Internet through balloons powered by solar energy

Alphabet is a technology corporation investing heavily in moonshot projects, when they have an entire department to nurture incredible projects called X Development. One of the companies investing in such projects is Loon, with the idea of ​​covering the Internet for rural areas through solar-powered balloons.

High-speed trains are still a long way off in the US, but they have been a "specialty" of Japan for decades

Today, super speed trains are an integral part of the Japanese people.

After World War II, Japan wanted to create a convenient, congested transportation system for residents between major cities - and their answer was the bullet train. In 1964, the land of the rising sun successfully built the world's first high-speed train system, just in time for Japan to host the 1964 Summer Olympics.

The train is capable of traveling at about 60km / h, thus cutting the travel time between Tokyo and Osaka in half. By 1976, after 12 years of operation, the Japanese high-speed train system served a total of over 1 billion passengers - a staggering number.

Before 1960, birth control pills were still an unrealistic idea

At the time before 1938, the United States banned all forms of contraception, making the family planning research efforts in the country completely stalled. It was not until more than 10 years later, in the 50s of the last century, that social activist Margaret Sanger was able to persuade an anonymous sponsor to invest in the research and manufacture of birth control pills. By 1960, this drug was certified and licensed by the US Food and Drug Administration.

And perhaps we don't need to say much about the major role contraceptives play in family planning, not only in the US, but also around the world.

The father of the "DNA Imprint" technique could not believe that he had created this technique

DNA Fingerprinting is a very important technique to assist in investigating many cases.

In 1984 , the technique of "DNA Imprint" - helping to decode special sequences of DNA sequences, from which using DNA as a form of human identification - was discovered. At the time, however, the father of this technique - researcher Alec Jeffreys at the University of Leicester - did not believe he had invented a new technique.

This technique quickly became a vital part of the investigation force's ability to solve difficult cases, as well as providing a very reliable way to identify the blood of children. .

3D printing technology was created thanks to a hunch

Today, we can 3D print chocolate as well.

In 1983, inventor Chuck Hall suddenly had a hunch that UV technology could be used to turn computer designs into real-life objects. Then one night, Chuck Hall turned his hunch to reality after an experiment with acrylic-based solutions.

The above experiment is the premise for creating 3D printing technology, which has gradually become popular when applied in many different production areas in life.

"Virtual reality" which is considered technology only exists in science fiction

Virtual reality is a technology that many big corporations invest in at the moment.

A few dozen years ago, virtual reality technology only appeared in fiction books, in films like Star Trek or Matrix. What about today? Virtual reality technology is becoming more and more popular in the gaming industry, as well as in many other areas of life such as health or education.

Even now, people use virtual reality technology in breeding, like the way a farm in Russia has done with its dairy cows.
