What inventions and discoveries have been made by mankind in the 20th century

Xu Guangda is an individual in Guangdong Province.

As follows:

1. Airplanes. The airplane is one of the most significant inventions of the early 20th century, recognized as invented by the American Wright brothers. Their flight on December 17, 1903, was recognized by the Fédération Internationale de Nautical (FAI) as "the first controlled, sustained powered flight of a heavier-than-air aircraft", and in the same year they founded the Wright Aircraft Company.

2. Computer.

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.

Introduce. Invention is the process and result of applying the laws of nature to solve unique problems in the field of technology and proposing innovative solutions and measures.

In order to meet the needs of people's daily life, the invention provides an unprecedented model of artificial natural objects, provides new processes and methods of processing and production, as well as machinery and equipment, instrumentation and various consumer products, and innovates and transforms manufacturing processes, production processes and detection and control methods.

1. Atoms. In 1900, the German scientist Planck discovered that when the atom is fission, it will release a huge amount of energy, which he called "quart", and this discovery is known as the discovery of the century.

2. Airplanes. Aircraft On December 17, 1903, the first powered aircraft began to fly. In 1933, the world's first regular air route was opened, which greatly expanded the space for human activities.

3. Radio.

In 1895, the Italian Makeni successfully invented radio communication.

In 1948 the semiconductor radio was invented.

4. Watches. One of the most changed inventions in the history of the watch appeared in 1904.

5. a photocopier.

In 1907, the world's first photocopiers appeared in New York, USA, and in 1959, the Xerox 914 electrostatic resuming caller was launched on the market, and photocopiers began to be widely used.

6. Chloromycin.

1928 Penicillin: Penicillin is said to be the most important drug of the century, and its inventor was the British bacteriologist Alexander Fleming. In 1928, during a bacterial culture experiment, the inventor stumbled upon a mold that would later become known as penicillin devouring bacteria he had grown in a petri dish.

According to the results of Fleming's research, researchers at the University of Oxford in the United Kingdom finally found a way to refine this mold after ten years of hard work and put it into medical experiments. In 1943, in order to heal soldiers wounded in World War II, the Allies began to put penicillin into industrial production. For more than half a century, penicillin has saved countless lives and prompted people to pay attention to the research and development of the Mori Hood mill antibiotic family.

Penicillin (i.e., penicillin) was first developed by Fleming in the United Kingdom in 1929 and used in 1941 for soldiers wounded in World War II, and is known as the second invention after the atomic bomb.
