What other myths have been created by science and technology in the 20th century as follows:
1. The birth of television is one of the greatest inventions of the 20th century. Life without television is unimaginable in modern society.
Various kinds of fully functional black and white and color TV constantly from a production line into factories, schools, hospitals and families around the world, quickly and miraculously changed people's lives.
2. In 1935, the U.S. organic chemist Carothers synthesized polymers from adipic acid and adipic diamine. Because both components contained six carbon atoms, it was then called Polymer 66.
He then melted the polymer and compressed it through an injection needle called a fiber. The fiber was polyamide 66 fiber, which became known as nylon when it was industrialized in 1939. It became the world's first industrialized chemical fiber.
3. In 1960, Meyman developed the world's first practical ruby laser. This is a sign of the birth of laser technology.
In recent years, laser technology has been developing rapidly and has been widely used and extensively researched in the fields of laser preservation, laser breeding, laser medicine and laser beauty.
Previously, people have been racking their brains for the preservation of vegetables at room temperature, but now laser has easily solved this problem. Such as vegetables transported over long distances, with a laser scanning can be shipped, on the way to ten days eight days is still fresh as usual. The mechanism is very simple, the laser energy is large when the inhibition of vegetable growth.
On the contrary, its energy is suitable for its growth conditions can be catalyzed, so the laser breeding has been promoted. The use of laser irradiation of crop seeds, can make the traits of mutation, thereby increasing crop yields.
4. British electrical engineer John Baird invented the television, and the first television was sold in 1923 when he invented a device that could produce eight lines of images. The BBC launched the world's first standardized television program in 1932.
5. Nylon was synthesized by Carothers in 1935 from adipic acid and hexanediamine. He then melted this polymer and extruded it with a syringe. This nylon 66 fiber was industrially produced in 1939, and called "Nylon", is the first industrial production of man-made fibers.
6, 1869, the earliest man-made plastic celluloid patented. Celluloid was the first man-made plastic, but it was a man-made plastic, not a synthetic plastic.
The first synthetic plastic is a phenolic resin molded with heat, which was made in the early 20th century, in 1910, by the American-Belgian chemist Beckerland.
