Famous inventors of the world have created a lot of useful things for mankind. Their benefit to society is difficult to overestimate. Many ingenious discoveries have saved more than one life. Who are they - inventors known for their unique developments?
Archimedes
This man was not only a great mathematician. Thanks to him, the whole world learned what a mirror and a siege weapon are. One of the most famous developments is the Archimedean screw (auger), with which you can effectively scoop out water. It is noteworthy that this technology is still used today.
Leonardo da Vinci
Inventors, known for their brilliant ideas, did not always have the opportunity to bring ideas to life. For example, drawings of a parachute, an airplane, a robot, a tank and a bicycle, which appeared as a result of the painstaking work of Leonardo da Vinci, remained unclaimed for a long time. At that time, there were simply no engineers and opportunities to implement such grandiose plans.
Thomas Edison
The inventor of the phonograph, kinescope and telephone microphone wasfamous American scientist. In January 1880, he filed a patent for an incandescent lamp, which later glorified Edison throughout the planet. However, some do not consider him a genius, noting that the inventors known for their developments worked alone. As for Edison, he had a whole group of people helping him.
Nikola Tesla
The great inventions of this genius were brought to life only after his death. Everything is explained simply: Tesla was such a closed person that no one knew about his work. Thanks to the efforts of the scientist, a multi-phase electric current system was discovered, which led to the emergence of commercial electricity. In addition, he formed the foundations of robotics, nuclear physics, computer science and ballistics.
Alexander Graham Bell
Many inventors known for their discoveries have helped make our lives even better. The same can be said about Alexander Bell. Thanks to his painstaking work, people were able to communicate freely, being thousands of kilometers apart, and all thanks to the phone. Bell also invented an audiometer - a special device that determines deafness; a device for searching for a treasure - a prototype of a modern metal detector; the world's first airplane; a model of a submarine, which Alexander himself called a hydrofoil boat.
Karl Benz
This scientist has successfully realized the main idea of his life: a meansmovement with a motor. It is thanks to him that we now have the opportunity to drive cars. Another valuable invention of Benz is the internal combustion engine. Later, a car manufacturing company was organized, which today is known throughout the world. This is Mercedes Benz.
Edwin Land
This famous French inventor dedicated his life to photography. In 1926, he managed to discover a new type of polarizer, which later became known as the Polaroid. Land founded Polaroid and patented 535 more inventions.
Charles Babbage
This English scientist worked on the creation of the first computer back in the nineteenth century. It was he who called the unique device a computer. Since at that time mankind did not have the necessary knowledge and experience, Babbage's efforts were not crowned with success. However, brilliant ideas have not sunk into oblivion: Howard Aiken and Konrad Zuse were able to realize them in the middle of the twentieth century.
Benjamin Franklin
This famous politician, writer, diplomat, satirist and statesman was also a scientist. The great inventions of mankind, which saw the light thanks to Franklin, are bifocal glasses, and a flexible urinary catheter, and a lightning rod. Interesting fact: Benjamin basically did not patent any of his discoveries, because he believed that all of them were the property of mankind.
Jerome Hal Lemelson
Such great inventions of mankind as the fax machine, cordless telephone,an automated warehouse and a magnetic tape cassette were introduced to the general public by Jerome Lemelson. In addition, this scientist developed diamond coating technology and some medical devices that help in the treatment of cancer.
Mikhail Lomonosov
This recognized genius of various sciences organized the first university in Russia. The most famous personal invention of Mikhail Vasilyevich is an aerodynamic machine. It was intended to raise special meteorological instruments. According to many experts, it is Lomonosov who is the author of the prototype of modern aircraft.
Ivan Kulibin
This man is not without reason called the brightest representative of the eighteenth century. Ivan Petrovich Kulibin from early childhood was interested in the principles of mechanics. Thanks to his work, we now use navigational instruments, alarm clocks, and water-powered engines. For that time, these inventions were something from the category of science fiction. The surname of the genius even became a household name. Kulibin is now called a person with the ability to make amazing discoveries.
Sergey Korolev
He was interested in manned astronautics, aircraft engineering, the design of rocket and space systems and missile weapons. Sergei Pavlovich greatly contributed to the exploration of outer space. He created the Vostok and Voskhod spaceships, the 217 anti-aircraft missile and the 212 long-range missile, as well as a rocket plane equipped with a missileengine.
Alexander Popov
It was this Russian scientist who invented the radio and the radio receiver. The unique discovery was preceded by years of research into the nature and propagation of radio waves.
The brilliant physicist and electrical engineer was born in the family of a priest. Alexander had six more brothers and sisters. Already in childhood, he was jokingly called a professor, because Popov was a shy, thin, awkward boy who could not stand fights and noisy games. At the Perm Theological Seminary, Alexander Stepanovich began to study physics based on Gano's book. His favorite pastime was assembling simple technical devices. The acquired skills were subsequently very useful to Popov when creating physical instruments for his own most important research.
Konstantin Tsiolkovsky
The discoveries of this great Russian inventor made it possible to bring aerodynamics and astronautics to a new level. In 1897, Konstantin Eduardovich finished working on a wind tunnel. Thanks to the allocated subsidies, he calculated the resistance of the ball, cylinder and other bodies. The data obtained were subsequently widely used in his work by Nikolai Zhukovsky.
In 1894, Tsiolkovsky designed an airplane with a metal frame, but the opportunity to build such an apparatus appeared only twenty years later.
Debatable issue. The inventor of the light bulb - who is he?
The creation of a device that gives light, worked in ancient times. The prototype of modern lamps were clay vessels with wicks made of cotton threads. ancientThe Egyptians poured olive oil into such containers and set it on fire. The inhabitants of the coast of the Caspian Sea used in similar devices another fuel material - oil. The first candles made in the Middle Ages consisted of beeswax. The notorious Leonardo da Vinci worked hard to create a kerosene lamp, but the world's first safe lighting device was invented in the nineteenth century.
The debate about who should be awarded the honorary title "Inventor of the light bulb" still does not subside. The first is often called Pavel Nikolaevich Yablochkov, who worked as an electrical engineer all his life. He created not only a lamp, but also an electric candle. The latter device is widely used in street lighting. The miracle candle burned for an hour and a half, after which the janitor had to change it for a new one.
In 1872-1873. Russian engineer-inventor Lodygin created an electric lamp in its modern sense. At first, it emitted light for thirty minutes, and after pumping air out of the device, this time increased significantly. In addition, Thomas Edison and Joseph Swan claimed the championship in the invention of the incandescent lamp.
Conclusion
Inventors around the world have given us many devices that make life more comfortable and varied. Progress does not stand still, and if a few centuries ago there were simply not enough technical capabilities to implement all the ideas, today it is much easier to bring ideas to life.
