What are the examples of invention and creation, and what are the examples of invention and creation

The invention of the helicopter.

In 1907, the world's first *** like a meandering was successfully developed by French engineers Burleg and Riche. The aircraft had no wings, and the first arm head had two pairs of four-bladed propellers that rotated horizontally. During the test flight, it was found that the aircraft vibrated badly and had poor safety performance.

It was not until after 1932 that the former Soviet engineer Bratukhin designed and manufactured a high-performance aircraft called the "Omega". Since then, *** has gradually become an important flying tool.

Watt invented the steam engine, Edison invented the electric light, and Marconi invented the telegraph.

Examples of inventions and creations include:

1. Edison.

The invention of the phonograph.

Edison is a famous American scientist and inventor, because he has more than 1,000 inventions such as electric lights, phonographs, movies and storage batteries, so people call him "the king of inventions" and "magician".

2. Watts. Invented the steam engine.

story. One summer morning, the weather was sunny and thrushes.

Singing a pleasant song in the trees. at the University of Glasgow, UK.

On campus, there is a person who is taking a walk. He paced slowly across the green lawn.

Sometimes he looked at the vast sky, sometimes at the playground, sometimes with a ......frownSuddenly, a smile appeared on his face, his mood suddenly brightened, he came up with it, he came up with an effective solution to the steam engine. He ran happily, his feet clear. In an instant, his figure appeared on the operating table that had been with him for many years.

He was Watt, the inventor of the steam engine.

3. The invention of radar.

Radar is a magical electrical apparatus that is made up of electromagnetic waves.

Round-trip time, the distance of the obstructor is measured. Suppose you ask who invented radar? In Fink's Radar Machinery, he says, "The invention of radar cannot be attributed to any one scientist, but is the result of the efforts of many radioscience engineers to study and tune it." ”

4. The invention of the lightning rod.

There is a well-known story about the invention of lightning rods in history. In 1752, the 46-year-old American scientist Benjamin Franklin.

I made a kite out of silk and put it into the sky with twine on a stormy day, and tied a metal key to the end of the twine, which became a conductor when the rain wetted the twine.

5. The story of Roland Hill's invention of stamps.

The development of human society has determined that human beings cannot survive on the earth for a long time by relying on the strength of individuals alone. Human beings need help, human beings need to communicate, and information transmission has become one of the basic activities necessary for human survival. At first, it was a gesture, but then language was invented to deliver a message through a marathon run.

Later, writing was invented and letters began to be transmitted, so there was an ancient post office.

1. Leonardo da Vinci invented the calculator. Leonardo da Vinci was the founder of the Renaissance, he could paint, sculpt, and invent. His diary, which fascinates the world to this day, depicts everything from the human body to *** and tanks.

2. Nikola Tesla invented the radio. A method of electricity transmission he invented called "alternating current" is still in use today, but in fact, the focus of his research is on the theoretical application of electricity. Tesla has made a range of perspectives ranging from X-rays to ** meters.

3. Alessandro Volt invented the battery. Volt has spent his entire life doing electric things. Early on, he invented the electric disc.

A year later, he worked on experiments with closed room gas ignition power generation, during which he discovered biogas. However, what really makes it famous is the "volt battery", which is actually a mixture of zinc and copper sheets arranged in an alternate arrangement, plus a cloth soaked in salt water between the two metal sheets to enhance electrical conductivity.

Examples created by China include: the compass, papermaking, printing, gunpowder, and the Shenzhou spacecraft.

1. Compass.

The compass is the result of the understanding of magnetism by the ancient Chinese working people in long-term practice. As one of the four great inventions of ancient China, its invention has played an immeasurable role in the development of human science and technology and civilization. In ancient China, the compass was first used in rituals, ceremonies, and military affairs.

2. Papermaking.

Papermaking is one of the four great inventions of China, which was invented in the Western Han Dynasty of the Han Dynasty and improved in the Eastern Han Dynasty of the Han Dynasty. In particular, the papermaking technique improved by Cai Lun in the Eastern Han Dynasty (also known as "Cai Hou paper") is a revolution in writing materials, which is easy to carry and takes a wide range of materials, and promotes the cultural development of China, Arabia, Europe and even the whole world.

3. Printing.

Printing is one of the four great inventions of the working people in ancient China. Block printing was invented in the Tang Dynasty and was widely used in the middle and late Tang Dynasty. Printing is the forerunner of modern human civilization and has created conditions for the wide dissemination and exchange of knowledge.

The printing technique of the citrus was successively spread to Korea, Japan, Central Asia, West Asia and Europe.

4. Gunpowder. Gunpowder is one of the four great inventions of China. Gunpowder is an outstanding achievement in the history of human civilization. Gunpowder has become one of the important inventions of human civilization because of its lethality and deterrence, bringing human beings the role of stopping war and security defense.

5. Shenzhou spacecraft.

The Shenzhou spacecraft is a spacecraft developed by China itself, with completely independent intellectual property rights, which is at or better than the international third-generation manned spacecraft technology. Compared with foreign third-generation spacecraft, the Shenzhou spacecraft has the characteristics of a high starting point and the ability to stay in orbit.
