Russian discoveries that changed the world. Inventions and discoveries of Russian scientists that changed the world

At all times, Russia has had enough inventors whose creations have been widely used throughout the world. It’s easier to just list our scientists and inventions and discoveries: Lomonosov, Kulibin, Mendeleev, Tsiolkovsky, Vernadsky, Pirogov, Mechnikov, Timiryazev, Pavlov, Zhukovsky, Kapitsa, Sechenov, Jacobi, Lodygin, Yablochkov, Zvorykin, Vavilov, Zelinsky, Lobachevsky, Dolivo-Dobrovolsky, Tamm, Tupolev, Polikarpov, Popov, Antonov, Chaplygin, Landau, Sikorsky, Chizhevsky, Kabalevsky, S. Kovalevskaya and many, many others. Such was the supposedly “bast-footed”, “backward”, “illiterate” Russian Empire, which learned and educated these wonderful scientists and engineers - the pride of all mankind.Let's remember some of the inventions of Russian inventors who helped make technical progress not only in Russia, but also far beyond its borders.

Electrotype

We so often come across products that look like metal, but are actually made of plastic and only covered with a layer of metal, that we have stopped noticing them. There are also metal products coated with a layer of another metal - for example, nickel. And there are metal products that are actually a copy of a non-metallic base. We owe all these miracles to the genius of physics Boris Jacobi - by the way, the older brother of the great German mathematician Carl Gustav Jacobi. Jacobi's passion for physics resulted in the creation of the world's first electric motor with direct shaft rotation, but one of his most important discoveries was electroplating - the process of depositing metal on a mold, allowing the creation of perfect copies of the original object. In this way, for example, sculptures were created on the naves of St. Isaac's Cathedral. Galvanoplasty can be used even at home. The electroforming method and its derivatives have found numerous applications. With its help, everything has not been done and is still not being done, right down to the cliché of state banks. Jacobi received the Demidov Prize for this discovery in Russia, and a large gold medal in Paris. Possibly also made using this same method.

Electric car

In the last third of the 19th century, the world was gripped by a form of electrical fever. That's why electric cars were made by everyone. This was the golden age of electric cars. The cities were smaller, and a range of 60 km on a single charge was quite acceptable. One of the enthusiasts was engineer Ippolit Romanov, who by 1899 had created several models of electric cabs. But that’s not even the main thing. Romanov invented and created in metal an electric omnibus for 17 passengers, developed a scheme of city routes for these ancestors of modern trolleybuses and received permission to work. True, at your own personal commercial peril and risk. The inventor was unable to find the required amount, to the great joy of his competitors - owners of horse-drawn horses and numerous cab drivers. However, the working electric omnibus aroused great interest among other inventors and remained in the history of technology as an invention killed by the municipal bureaucracy.

Pipeline transport

It is difficult to say what is considered the first real pipeline. One can recall the proposal of Dmitry Mendeleev, dating back to 1863, when he proposed to deliver oil from the production sites to the seaport at the Baku oil fields not in barrels, but through pipes. Mendeleev's proposal was not accepted, and two years later the first pipeline was built by the Americans in Pennsylvania. As always, when something is done abroad, they begin to do it in Russia. Or at least allocate money. In 1877, Alexander Bari and his assistant Vladimir Shukhov again came up with the idea of pipeline transport, already relying on American experience and again on the authority of Mendeleev. As a result, Shukhov built the first oil pipeline in Russia in 1878, proving the convenience and practicality of pipeline transport. The example of Baku, which was then one of the two leaders in world oil production, became infectious, and “getting on the pipe” became the dream of any enterprising person. In the photo: a view of a three-furnace cube. Baku, 1887.

Arc welding

Nikolai Benardos comes from Novorossiysk Greeks who lived on the Black Sea coast. He is the author of more than a hundred inventions, but he went down in history thanks to the electric arc welding of metals, which he patented in 1882 in Germany, France, Russia, Italy, England, the USA and other countries, calling his method “electrohephaestus”. Benardos's method spread across the planet like wildfire. Instead of fiddling with rivets and bolts, it was enough to simply weld pieces of metal. However, it took about half a century for welding to finally take a dominant position among installation methods. A seemingly simple method is to create an electric arc between a consumable electrode in the welder’s hands and the pieces of metal that need to be welded. But the solution is elegant. True, it did not help the inventor meet old age with dignity; he died in poverty in 1905 in an almshouse.

Multi-engine aircraft "Ilya Muromets"

It’s hard to believe now, but just over a hundred years ago it was believed that a multi-engine aircraft would be extremely difficult and dangerous to fly. The absurdity of these statements was proved by Igor Sikorsky, who in the summer of 1913 took into the air a twin-engine aircraft called Le Grand, and then its four-engine version, the Russian Knight. On February 12, 1914, in Riga, at the training ground of the Russian-Baltic Plant, the four-engine Ilya Muromets took off. There were 16 passengers on board the four-engine plane - an absolute record at that time. The plane had a comfortable cabin, heating, a bath with toilet and... a promenade deck. In order to demonstrate the capabilities of the aircraft, in the summer of 1914, Igor Sikorsky flew on the Ilya Muromets from St. Petersburg to Kyiv and back, setting a world record. During World War I, these aircraft became the world's first heavy bombers.

ATV and helicopter

Igor Sikorsky also created the first production helicopter, the R-4, or S-47, which the Vought-Sikorsky company began producing in 1942. It was the first and only helicopter to serve in World War II, in the Pacific theater of operations, as a staff transport and for casualty evacuation. However, it is unlikely that the US military department would have allowed Igor Sikorsky to boldly experiment with helicopter technology if not for the amazing rotary-wing machine of George Botezat, who in 1922 began testing his helicopter, which the American military ordered him. The helicopter was the first to actually take off from the ground and be able to stay in the air. The possibility of vertical flight was thus proven. Botezat's helicopter was called the "flying octopus" because of its interesting design. It was a quadcopter: four propellers were placed at the ends of metal trusses, and the control system was located in the center - exactly like modern radio-controlled drones.

Color photo

Color photography appeared at the end of the 19th century, but photographs of that time were characterized by a shift to one or another part of the spectrum. Russian photographer Sergei Prokudin-Gorsky was one of the best in Russia and, like many of his colleagues around the world, dreamed of achieving the most natural color rendition. In 1902, Prokudin-Gorsky studied color photography in Germany with Adolf Miethe, who by that time was a worldwide star of color photography. Returning home, Prokudin-Gorsky began to improve the chemistry of the process and in 1905 he patented his own sensitizer, that is, a substance that increases the sensitivity of photographic plates. As a result, he was able to produce negatives of exceptional quality. Prokudin-Gorsky organized a number of expeditions across the territory of the Russian Empire, photographing famous people (for example, Leo Tolstoy), peasants, churches, landscapes, factories, thus creating an amazing collection of colorful Russia. Prokudin-Gorsky's demonstrations aroused great interest in the world and pushed other specialists to develop new principles of color printing.

Parachute

As you know, the idea of a parachute was proposed by Leonardo da Vinci, and several centuries later, with the advent of aeronautics, regular jumps from balloons began: parachutes were suspended under them in a partially opened state. In 1912, the American Barry was able to leave the plane with such a parachute and, importantly, landed on the ground alive. The problem was solved in every possible way. For example, the American Stefan Banich made a parachute in the form of an umbrella with telescopic spokes that were attached around the pilot’s torso. This design worked, although it was still not very convenient. But engineer Gleb Kotelnikov decided that it was all about the material, and made his parachute from silk, packing it in a compact backpack. Kotelnikov patented his invention in France on the eve of the First World War. But besides the backpack parachute, he came up with another interesting thing. He tested the opening ability of the parachute by opening it while the car was moving, which literally stood rooted to the spot. So Kotelnikov came up with a braking parachute as an emergency braking system for aircraft.

Theremin

The history of this musical instrument, which produces strange “cosmic” sounds, began with the development of alarm systems. It was then that the descendant of the French Huguenots, Lev Theremin, in 1919, drew attention to the fact that changing the position of the body near the antennas of the oscillatory circuits affects the volume and tonality of the sound in the control speaker. Everything else was a matter of technique. And marketing: Theremin showed his musical instrument to the leader of the Soviet state, Vladimir Lenin, an enthusiast of the cultural revolution, and then demonstrated it in the States.

The life of Lev Theremin was difficult; he knew ups, glory, and camps. His musical instrument still lives today. The coolest version is the Moog Etherwave. The theremin can be heard among the most advanced and quite pop performers. This is truly an invention for all times.

Color television

Vladimir Zvorykin was born into a merchant family in the city of Murom. Since childhood, the boy had the opportunity to read a lot and carry out all sorts of experiments - his father encouraged this passion for science in every possible way. Having started studying in St. Petersburg, he learned about cathode ray tubes and came to the conclusion that the future of television lay in electronic circuits. Zvorykin was lucky; he left Russia on time in 1919. He worked for many years and in the early 30s he patented a transmitting television tube - an iconoscope. Even earlier, he designed one of the variants of the receiving tube - a kinescope. And then, already in the 1940s, he split the light beam into blue, red and green colors and got color TV. In addition, Zvorykin developed a night vision device, an electron microscope and many other interesting things. He invented throughout his long life and even in retirement continued to amaze with his new solutions.

Video recorder

The AMPEX company was created in 1944 by Russian emigrant Alexander Matveevich Ponyatov, who took three letters of his initials for the name and added EX - short for “excellent”. At first, Ponyatov produced sound recording equipment, but in the early 50s he focused on developing video recording. By that time, there had already been experiments in recording television images, but they required a huge amount of tape. Ponyatov and colleagues proposed recording the signal across the tape using a block of rotating heads. On November 30, 1956, the first previously recorded CBS News aired. And in 1960, the company, represented by its leader and founder, received an Oscar for its outstanding contribution to the technical equipment of the film and television industry. Fate brought Alexander Ponyatov together with interesting people. He was a competitor of Zvorykin, Ray Dolby, the creator of the famous noise reduction system, worked with him, and one of the first clients and investors was the famous Bing Crosby. And one more thing: by order of Ponyatov, birch trees were necessarily planted near any office - in memory of the Motherland.

Tetris

A long time ago, 30 years ago, the “Pentamino” puzzle was popular in the USSR: you had to place various figures consisting of five squares on a lined field. Even collections of problems were published, and the results were discussed. From a mathematical point of view, such a puzzle was an excellent test for a computer. And so, a researcher at the Computing Center of the USSR Academy of Sciences, Alexey Pajitnov, wrote such a program for his computer “Electronics 60”. But there wasn’t enough power, and Alexey removed one cube from the figures, that is, he made a “tetromino”. Well, then the idea came to have the figures fall into the “glass”. This is how Tetris was born. It was the first computer game from behind the Iron Curtain, and for many people the first computer game at all. And although many new toys have already appeared, Tetris still attracts with its apparent simplicity and real complexity.

There are inventions in the world created for our entertainment, comfort and coziness, such as a lighter or kitchen utensils. Undoubtedly, they are very useful and extremely practical. At the same time, there are also innovations that have completely changed the way of our lives - inventions that have influenced the history and way of life of man.

In this article, I offer for your consideration a list of 10 inventions, ranging in age from 800,000 years to several decades, all of which, however, have made our lives easier and more convenient. Representing various aspects of life, all these inventions play a huge role in human life.

Fire

Imagine the face of an ancient man who first produced fire, and did it on his own, without the help of lightning or a forest fire. New archaeological excavations carried out in Israel claim that X-Day took place approximately 800,000 years ago, when the planet was still dominated by Homo erectus, the upright man. This species of man was the first of our ancestors to learn how to make fire by striking silicon (a type of quartz) against another mineral containing metal. The spark that jumped out as a result of the impact of two stones created the fire.

The advent of this technology was a breakthrough for man: suddenly he had a warm, bright parking lot, processed food and a completely new menu of foods that could be cooked over a fire.

Wheel

Despite the hackneyed nature of the invention, it undoubtedly has a place in the top ten, because it is not just an innovation, but an invention of inventions, since the wheel technology was subsequently used in many iconic inventions. The first wheel known to science dates back to 3,500 BC, and was found in Mesopotamia. Initially, the wheel was used for pottery. Then, apparently realizing the potential of the invention, people began to use the wheel in transport, which significantly expanded the human habitat.

Concrete

Another example of an important innovation that disappeared during the Dark Ages was concrete, an early recipe for which was known to the ancient Egyptians (scientists believe it was used in the construction of the pyramids). The ancient Romans adopted the technology from their eastern counterparts, and actively used it in the construction of, for example, the Roman Pantheon, a monument that has survived to this day.

The technology of mixing cement and binding elements such as sand and water had virtually disappeared by the 18th century, when the English engineer John Smeaton improved the composition of concrete. This material is still the main source of construction material for the creation of bridges, dams, roads and buildings.

Electricity

Where would humanity be without electricity? Well, you probably wouldn’t read this list. It is difficult for a modern person to imagine a time when the world did without electricity. However, thanks to the efforts of scientists such as Nikola Tesla, Michael Faraday and Thomas Edison, by the end of the 19th century the world learned about electricity. The invention was so successful that the first power plants appeared in the United States by the 1880s. However, for a long time, electricity remained only the province of large cities. By the 1930s, only 10% of villages were connected to electrical networks.

Microscope

Most inventions are the result of big-picture thinking. The microscope, a mechanical creation that allowed us to see a completely different life, is an example of how discoveries can be made on such a small scale.

The first microscope used light and lenses to optically magnify small specimens. Created in the late 16th and early 17th centuries by Dutch masters, the first scientific use of the microscope dates back to the Englishman Robert Hook, who decided to examine a louse and a flea under the instrument.

A television

Television is a classic example of how engineering innovations, developing separately from each other, were able, combined into a single device, to revolutionize the way people live.

One of the most significant inventions of the 20th century began with the concept of creating a device that played moving pictures to music. However, the world decided differently, and by 1920 television had become a reality, and the post-war period is usually called the “era of television.”

Antibiotics

Until the beginning of the 20th century, it was very difficult to live to old age - every day dozens of potential killers awaited a person, from tuberculosis bacilli to other dangerous infections.

Everything changed in the 1930s when Scottish biologist Alexander Fleming accidentally discovered penicillin, an antibiotic that could successfully fight bacterial infections. This discovery became one of the most important discoveries in medicine, and began to save people's lives immediately after the launch of production. It is to the success of penicillin that the modern pharmaceutical industry owes its prosperity.

Computer

The Internet has turned the computer into a truly fantastic device, but would cyberspace exist without the corresponding hardware support? The computer is another invention that initially had a less rosy fate, although most historians point to the fact that the first programmable computer, the Z3, was invented by German engineer Konrad Zuse in the 1930s. A secret project sponsored by the Nazi government was destroyed during the war. However, the original technology used by the German scientist to create the Z3 continues to live on today.

Iron processing

Iron is one of the most abundant metals on Earth, and steel, its alloy, is an essential material. Moreover, iron processing is as important today as it was thousands of years ago. Iron was first worked around 3,500 years ago in Anatolia (in modern-day Turkey), and the transition from the Bronze Age to the Iron Age was a major force for agriculture in the ancient world, as stronger iron tools allowed people to better work the land. More advanced weapons, although they led to a series of aggressive wars, also contributed to a more flexible development of society and its consolidation.

Flush toilet

The flush toilet may be considered a modern invention, but ancient societies successfully used this item of public life. Already 5,000 years ago, private houses in Pakistan had toilets connected by pipes to a drainage system. Unfortunately, the invention was lost with the Dark Ages that came to Europe. Again, flush toilets replaced holes in the floor and wooden chairs with a hole only in the 16th century, when the English aristocrat John Harrington created a toilet using a flush mechanism for Queen Elizabeth I.

The history of mankind is closely connected with constant progress, development of technology, new discoveries and inventions. Some technologies are outdated and become history, others, such as the wheel or sail, are still in use today. Countless discoveries were lost in the whirlpool of time, others, not appreciated by their contemporaries, waited for recognition and implementation for tens and hundreds of years.

Editorial Samogo.Net conducted her own research designed to answer the question of which inventions are considered the most significant by our contemporaries.

Processing and analysis of the results of online surveys showed that there is simply no consensus on this matter. Nevertheless, we managed to form an overall unique rating of the greatest inventions and discoveries in human history. As it turned out, despite the fact that science has long moved forward, basic discoveries remain the most significant in the minds of our contemporaries.

First place undoubtedly took Fire

People early discovered the beneficial properties of fire - its ability to illuminate and warm, to change plant and animal food for the better.

The “wild fire” that broke out during forest fires or volcanic eruptions was terrible for man, but by bringing fire into his cave, man “tamed” it and “put” it into his service. From that time on, fire became a constant companion of man and the basis of his economy. In ancient times, it was an indispensable source of heat, light, a means of cooking, and a hunting tool.
However, further cultural achievements (ceramics, metallurgy, steelmaking, steam engines, etc.) are due to the complex use of fire.

For many millennia, people used “home fire”, maintaining it year after year in their caves, before they learned to produce it themselves using friction. This discovery probably happened by accident, after our ancestors learned to drill wood. During this operation, the wood was heated and, under favorable conditions, ignition could occur. Having paid attention to this, people began to widely use friction to make fire.

The simplest method was to take two sticks of dry wood, and make a hole in one of them. The first stick was placed on the ground and pressed with the knee. The second one was inserted into the hole, and then they began to quickly and quickly rotate it between the palms. At the same time, it was necessary to press hard on the stick. The inconvenience of this method was that the palms gradually slid down. Every now and then I had to lift them up and continue rotating again. Although, with certain dexterity, this can be done quickly, nevertheless, due to constant stops, the process was greatly delayed. It is much easier to make fire by friction, working together. In this case, one person held the horizontal stick and pressed on top of the vertical one, and the second quickly rotated it between his palms. Later, they began to clasp the vertical stick with a strap, moving it to the right and left to speed up the movement, and for convenience, they began to put a bone cap on the upper end. Thus, the entire device for making fire began to consist of four parts: two sticks (fixed and rotating), a strap and an upper cap. In this way, it was possible to make fire alone, if you pressed the lower stick with your knee to the ground and the cap with your teeth.

And only later, with the development of mankind, other methods of producing open fire became available.

Second place in the responses of the online community they ranked Wheel and Cart

It is believed that its prototype may have been rollers that were placed under heavy tree trunks, boats and stones when dragging them from place to place. Perhaps the first observations of the properties of rotating bodies were made at the same time. For example, if for some reason the log roller was thinner in the center than at the edges, it moved more evenly under the load and did not skid to the side. Noticing this, people began to deliberately burn the rollers in such a way that the middle part became thinner, while the sides remained unchanged. Thus, a device was obtained, which is now called a “ramp.” In the course of further improvements in this direction, only two rollers at its ends remained from a solid log, and an axis appeared between them. Later they began to be made separately and then rigidly fastened together. Thus the wheel in the proper sense of the word was discovered and the first cart appeared.

In subsequent centuries, many generations of craftsmen worked to improve this invention. Initially, solid wheels were rigidly attached to the axle and rotated with it. When traveling on a flat road, such carts were quite suitable for use. When turning, when the wheels must rotate at different speeds, this connection creates great inconvenience, since a heavily loaded cart can easily break or tip over. The wheels themselves were still very imperfect. They were made from a single piece of wood. Therefore, the carts were heavy and clumsy. They moved slowly, and were usually harnessed to slow but powerful oxen.

One of the oldest carts of the described design was found during excavations in Mohenjo-Daro. A major step forward in the development of transportation technology was the invention of a wheel with a hub mounted on a fixed axle. In this case, the wheels rotated independently of each other. And so that the wheel rubs against the axle less, they began to lubricate it with grease or tar.

To reduce the weight of the wheel, cutouts were cut out in it, and for rigidity they were reinforced with transverse braces. It was impossible to come up with anything better in the Stone Age. But after the discovery of metals, wheels with a metal rim and spokes began to be made. Such a wheel could rotate tens of times faster and was not afraid of hitting rocks. By harnessing fleet-footed horses to a cart, man significantly increased the speed of his movement. It is perhaps difficult to find another discovery that would give such a powerful impetus to the development of technology.

Third place rightfully occupied Writing

There is no need to talk about how great the invention of writing was in the history of mankind. It is impossible to even imagine what path the development of civilization could have taken if, at a certain stage of their development, people had not learned to record the information they needed with the help of certain symbols and thus transmit and store it. It is obvious that human society in the form in which it exists today simply could not have appeared.

The first forms of writing in the form of specially inscribed characters appeared about 4 thousand years BC. But long before this, there were various ways of transmitting and storing information: with the help of branches folded in a certain way, arrows, smoke from fires and similar signals. From these primitive warning systems, more complex methods of recording information later emerged. For example, the ancient Incas invented an original “writing” system using knots. For this purpose, wool laces of different colors were used. They were tied with various knots and attached to a stick. In this form, the “letter” was sent to the addressee. There is an opinion that the Incas used such “knot writing” to record their laws, write down chronicles and poems. “Knot writing” was also noted among other peoples - it was used in ancient China and Mongolia.

However, writing in the proper sense of the word appeared only after people invented special graphic signs to record and transmit information. The oldest type of writing is considered pictographic. A pictogram is a schematic drawing that directly depicts the things, events, and phenomena in question. It is assumed that pictography was widespread among various peoples during the last stage of the Stone Age. This letter is very visual, and therefore does not require special study. It is quite suitable for transmitting small messages and for recording simple stories. But when the need arose to convey some complex abstract thought or concept, the limited capabilities of the pictogram were immediately felt, which was completely unsuited to recording what could not be depicted in pictures (for example, such concepts as vigor, courage, vigilance, good sleep, heavenly azure, etc.). Therefore, already at an early stage in the history of writing, the number of pictograms began to include special conventional icons that denote certain concepts (for example, the sign of crossed hands symbolized exchange). Such icons are called ideograms. Ideographic writing also arose from pictographic writing, and one can quite clearly imagine how this happened: each pictorial sign of a pictogram began to become increasingly isolated from others and associated with a specific word or concept, denoting it. Gradually, this process developed so much that primitive pictograms lost their former clarity, but gained clarity and definiteness. This process took a long time, perhaps several thousand years.

The highest form of ideogram was hieroglyphic writing. It first appeared in Ancient Egypt. Later, hieroglyphic writing became widespread in the Far East - in China, Japan and Korea. With the help of ideograms it was possible to reflect any, even the most complex and abstract thought. However, for those not privy to the secrets of the hieroglyphs, the meaning of what was written was completely incomprehensible. Anyone who wanted to learn to write had to memorize several thousand symbols. In reality, this took several years of constant exercise. Therefore, in ancient times, few people knew how to write and read.

Only at the end of 2 thousand BC. The ancient Phoenicians invented a letter-sound alphabet, which served as a model for the alphabets of many other peoples. The Phoenician alphabet consisted of 22 consonant letters, each of which represented a different sound. The invention of this alphabet was a big step forward for humanity. With the help of the new letter it was easy to convey any word graphically, without resorting to ideograms. It was very easy to learn. The art of writing has ceased to be the privilege of the enlightened. It became the property of the entire society, or at least a large part of it. This was one of the reasons for the rapid spread of the Phoenician alphabet throughout the world. It is believed that four-fifths of all currently known alphabets arose from Phoenician.

Thus, from a variety of Phoenician writing (Punic) Libyan developed. The Hebrew, Aramaic and Greek writing came directly from Phoenician. In turn, on the basis of the Aramaic script, Arabic, Nabataean, Syriac, Persian and other scripts developed. The Greeks made the last important improvement to the Phoenician alphabet - they began to denote not only consonants, but also vowel sounds with letters. The Greek alphabet formed the basis of most European alphabets: Latin (from which French, German, English, Italian, Spanish and other alphabets in turn originated), Coptic, Armenian, Georgian and Slavic (Serbian, Russian, Bulgarian, etc.).

Fourth place, takes after writing Paper

Its creators were the Chinese. And this is no coincidence. Firstly, China, already in ancient times, was famous for its book wisdom and complex system of bureaucratic management, which required constant reporting from officials. Therefore, there has always been a need for inexpensive and compact writing material. Before the invention of paper, people in China wrote either on bamboo tablets or on silk.

But silk was always very expensive, and bamboo was very bulky and heavy. (An average of 30 hieroglyphs were placed on one tablet. It is easy to imagine how much space such a bamboo “book” must have taken up. It is no coincidence that they write that a whole cart was required to transport some works.) Secondly, only the Chinese knew the secret of production for a long time silk, and papermaking developed from one technical operation of processing silk cocoons. This operation consisted of the following. Women engaged in sericulture boiled silkworm cocoons, then, laying them out on a mat, dipped them into water and ground them until a homogeneous mass was formed. When the mass was taken out and the water was filtered out, silk wool was obtained. However, after such mechanical and thermal treatment, a thin fibrous layer remained on the mats, which, after drying, turned into a sheet of very thin paper suitable for writing. Later, workers began to use rejected silkworm cocoons for purposeful paper production. At the same time, they repeated the process that was already familiar to them: they boiled the cocoons, washed and crushed them to obtain paper pulp, and finally dried the resulting sheets. Such paper was called “cotton paper” and was quite expensive, since the raw material itself was expensive.

Naturally, in the end the question arose: can paper be made only from silk, or can any fibrous raw material, including plant origin, be suitable for preparing paper pulp? In 105, a certain Cai Lun, an important official at the court of the Han emperor, prepared a new type of paper from old fishing nets. It was not as good as silk, but was much cheaper. This important discovery had enormous consequences not only for China, but also for the whole world - for the first time in history, people received first-class and accessible writing material, for which there is no equivalent replacement to this day. The name of Tsai Lun is therefore rightfully included among the names of the greatest inventors in the history of mankind. In subsequent centuries, several important improvements were made to the papermaking process, allowing it to develop rapidly.

In the 4th century, paper completely replaced bamboo tablets from use. New experiments have shown that paper can be made from cheap plant materials: tree bark, reed and bamboo. The latter was especially important since bamboo grows in huge quantities in China. The bamboo was split into thin splinters, soaked in lime, and the resulting mass was then boiled for several days. The strained grounds were kept in special pits, thoroughly ground with special beaters and diluted with water until a sticky, mushy mass was formed. This mass was scooped out using a special form - a bamboo sieve mounted on a stretcher. A thin layer of mass along with the mold was placed under the press. Then the form was pulled out and only a sheet of paper remained under the press. The compressed sheets were removed from the sieve, piled, dried, smoothed and cut to size.

Over time, the Chinese have achieved the highest art in paper making. For several centuries, they, as usual, carefully kept the secrets of paper production. But in 751, during a clash with the Arabs in the foothills of the Tien Shan, several Chinese masters were captured. From them the Arabs learned to make paper themselves and for five centuries sold it very profitably to Europe. Europeans were the last of the civilized peoples who learned to make their own paper. The Spaniards were the first to adopt this art from the Arabs. In 1154, paper production was established in Italy, in 1228 in Germany, and in 1309 in England. In subsequent centuries, paper became widespread throughout the world, gradually conquering more and more new areas of application. Its significance in our lives is so great that, according to the famous French bibliographer A. Sim, our era can rightfully be called the “paper era.”

Fifth place occupied Gunpowder and Firearms

The invention of gunpowder and its spread in Europe had enormous consequences for the subsequent history of mankind. Although the Europeans were the last of the civilized peoples to learn how to make this explosive mixture, they were the ones who were able to derive the greatest practical benefit from its discovery. The rapid development of firearms and a revolution in military affairs were the first consequences of the spread of gunpowder. This, in turn, entailed profound social changes: armor-clad knights and their impregnable castles were powerless against the fire of cannons and arquebuses. Feudal society was dealt such a blow from which it could no longer recover. In a short time, many European powers overcame feudal fragmentation and became powerful centralized states.

There are few inventions in the history of technology that would lead to such grandiose and far-reaching changes. Before gunpowder became known in the West, it already had a long history in the East, and it was invented by the Chinese. The most important component of gunpowder is saltpeter. In some areas of China it was found in its native form and looked like flakes of snow dusting the ground. Later it was discovered that saltpeter is formed in areas rich in alkalis and decaying (nitrogen-delivering) substances. When lighting a fire, the Chinese could observe the flashes that occurred when saltpeter and coal burned.

The properties of saltpeter were first described by the Chinese physician Tao Hung-ching, who lived at the turn of the 5th and 6th centuries. Since that time, it has been used as a component of some medicines. Alchemists often used it when conducting experiments. In the 7th century, one of them, Sun Sy-miao, prepared a mixture of sulfur and saltpeter, adding to them several shares of locust wood. While heating this mixture in a crucible, he suddenly received a powerful flash of flame. He described this experience in his treatise Dan Jing. It is believed that Sun Si-miao prepared one of the first samples of gunpowder, which, however, did not yet have a strong explosive effect.

Subsequently, the composition of gunpowder was improved by other alchemists, who experimentally established its three main components: coal, sulfur and potassium nitrate. The medieval Chinese could not scientifically explain what kind of explosive reaction occurs when gunpowder is ignited, but they very soon learned to use it for military purposes. True, in their lives gunpowder did not have the revolutionary influence that it later had on European society. This is explained by the fact that for a long time the craftsmen prepared the powder mixture from unrefined components. Meanwhile, unrefined saltpeter and sulfur containing foreign impurities did not give a strong explosive effect. For several centuries, gunpowder was used exclusively as an incendiary agent. Later, when its quality improved, gunpowder began to be used as an explosive in the manufacture of land mines, hand grenades and explosive packages.

But even after this, for a long time they did not think of using the power of the gases generated during the combustion of gunpowder to throw bullets and cannonballs. Only in the 12th-13th centuries did the Chinese begin to use weapons that were very vaguely reminiscent of firearms, but they invented firecrackers and rockets. The Arabs and Mongols learned the secret of gunpowder from the Chinese. In the first third of the 13th century, the Arabs achieved great skill in pyrotechnics. They used saltpeter in many compounds, mixing it with sulfur and coal, adding other components to them and setting up fireworks of amazing beauty. From the Arabs, the composition of the powder mixture became known to European alchemists. One of them, Mark the Greek, already in 1220 wrote down in his treatise a recipe for gunpowder: 6 parts of saltpeter to 1 part of sulfur and 1 part of coal. Later, Roger Bacon wrote quite accurately about the composition of gunpowder.

However, another hundred years passed before this recipe ceased to be a secret. This secondary discovery of gunpowder is associated with the name of another alchemist, the Feiburg monk Berthold Schwartz. One day he began to pound a crushed mixture of saltpeter, sulfur and coal in a mortar, which resulted in an explosion that singed Berthold's beard. This or other experience gave Berthold the idea of using the power of powder gases to throw stones. He is believed to have made one of the first artillery pieces in Europe.

Gunpowder was originally a fine flour-like powder. It was not convenient to use, since when loading guns and arquebuses, the powder pulp stuck to the walls of the barrel. Finally, they noticed that gunpowder in the form of lumps was much more convenient - it was easy to charge and, when ignited, produced more gases (2 pounds of gunpowder in lumps gave a greater effect than 3 pounds in pulp).

In the first quarter of the 15th century, for convenience, they began to use grain gunpowder, which was obtained by rolling the powder pulp (with alcohol and other impurities) into a dough, which was then passed through a sieve. To prevent the grains from grinding during transportation, they learned to polish them. To do this, they were placed in a special drum, when spun, the grains hit and rubbed against each other and became compacted. After processing, their surface became smooth and shiny.

Sixth place ranked in the polls : telegraph, telephone, Internet, radio and other types of modern communications

Until the middle of the 19th century, the only means of communication between the European continent and England, between America and Europe, between Europe and the colonies was steamship mail. Incidents and events in other countries were learned about with a delay of weeks, and sometimes even months. For example, news from Europe to America was delivered in two weeks, and this was not the longest time. Therefore, the creation of the telegraph met the most urgent needs of mankind.

After this technical novelty appeared in all corners of the world and telegraph lines encircled the globe, it took only hours, and sometimes minutes, for the news to travel along electrical wires from one hemisphere to the other. Political and stock market reports, personal and business messages could be delivered to interested parties on the same day. Thus, the telegraph should be considered one of the most important inventions in the history of civilization, because with it the human mind achieved the greatest victory over distance.

With the invention of the telegraph, the problem of transmitting messages over long distances was solved. However, the telegraph could only send written dispatches. Meanwhile, many inventors dreamed of a more advanced and communicative method of communication, with the help of which it would be possible to transmit the live sound of human speech or music over any distance. The first experiments in this direction were undertaken in 1837 by the American physicist Page. The essence of Page's experiments was very simple. He assembled an electrical circuit that included a tuning fork, an electromagnet, and galvanic elements. During its vibrations, the tuning fork quickly opened and closed the circuit. This intermittent current was transmitted to an electromagnet, which just as quickly attracted and released a thin steel rod. As a result of these vibrations, the rod produced a singing sound, similar to that produced by a tuning fork. Thus, Page showed that it is in principle possible to transmit sound using electric current, it is only necessary to create more advanced transmitting and receiving devices.

And later, as a result of long searches, discoveries and inventions, the mobile phone, television, Internet and other means of communication of mankind appeared, without which it is impossible to imagine our modern life.

Seventh place ranked in the top 10 according to survey results Automobile

The automobile is one of those greatest inventions that, like the wheel, gunpowder or electric current, had a colossal influence not only on the era that gave birth to them, but also on all subsequent times. Its multi-faceted impact extends far beyond the transport sector. The automobile shaped modern industry, gave birth to new industries, and despotically restructured production itself, giving it a mass, serial, and in-line character for the first time. It transformed the appearance of the planet, which was surrounded by millions of kilometers of highways, put pressure on the environment and even changed human psychology. The influence of the car is now so multifaceted that it is felt in all spheres of human life. It has become, as it were, a visible and visual embodiment of technological progress in general, with all its advantages and disadvantages.

There have been many amazing pages in the history of the car, but perhaps the most striking of them dates back to the first years of its existence. One cannot help but be amazed by the speed with which this invention has gone from inception to maturity. It only took a quarter of a century for the car to turn from a capricious and still unreliable toy into the most popular and widespread vehicle. Already at the beginning of the 20th century, it was identical in its main features to a modern car.

The immediate predecessor of the gasoline car was the steam car. The first practical steam car is considered to be a steam cart built by the Frenchman Cugnot in 1769. Carrying up to 3 tons of cargo, it moved at a speed of only 2-4 km/h. She also had other shortcomings. The heavy car had very poor steering control and constantly ran into the walls of houses and fences, causing destruction and suffering considerable damage. The two horsepower that its engine developed were difficult to achieve. Despite the large volume of the boiler, the pressure dropped quickly. Every quarter of an hour, to maintain pressure, we had to stop and light the firebox. One of the trips ended in a boiler explosion. Fortunately, Cugno himself remained alive.

Cugno's followers were luckier. In 1803, Trivaitik, already known to us, built the first steam car in Great Britain. The car had huge rear wheels about 2.5 m in diameter. A boiler was attached between the wheels and the rear of the frame, which was served by a fireman standing on the back. The steam car was equipped with a single horizontal cylinder. From the piston rod, through the connecting rod and crank mechanism, the drive gear rotated, which was meshed with another gear mounted on the axis of the rear wheels. The axle of these wheels was hinged to the frame and turned using a long lever by the driver sitting on a high beam. The body was suspended on high C-shaped springs. With 8-10 passengers, the car reached speeds of up to 15 km/h, which, undoubtedly, was a very good achievement for that time. The appearance of this amazing car on the streets of London attracted a lot of onlookers who did not hide their delight.

The car in the modern sense of the word appeared only after the creation of a compact and economical internal combustion engine, which made a real revolution in transport technology.
The first gasoline-powered car was built in 1864 by the Austrian inventor Siegfried Marcus. Fascinated by pyrotechnics, Marcus once set fire to a mixture of gasoline vapor and air with an electric spark. Amazed by the force of the ensuing explosion, he decided to create an engine in which this effect could be used. In the end, he managed to build a two-stroke gasoline engine with electric ignition, which he installed on an ordinary cart. In 1875, Marcus created a more advanced car.

The official fame of the inventors of the car belongs to two German engineers - Benz and Daimler. Benz designed two-stroke gas engines and owned a small factory for their production. The engines were in good demand, and the Benz business flourished. He had enough money and leisure for other developments. Benz's dream was to create a self-propelled carriage powered by an internal combustion engine. Benz's own engine, like Otto's four-stroke engine, was not suitable for this, since they had a low speed (about 120 rpm). When the speed dropped slightly, they stalled. Benz understood that a car equipped with such an engine would stop at every bump. What was needed was a high-speed engine with a good ignition system and an apparatus for forming a combustible mixture.

Cars were rapidly improving Back in 1891, Edouard Michelin, owner of a rubber products factory in Clermont-Ferrand, invented a removable pneumatic tire for a bicycle (a Dunlop tube was poured into the tire and glued to the rim). In 1895, production of removable pneumatic tires for cars began. These tires were first tested in the same year at the Paris - Bordeaux - Paris race. The Peugeot equipped with them barely made it to Rouen, and then was forced to retire from the race, as the tires were continuously punctured. Nevertheless, specialists and car enthusiasts were amazed at the smooth running of the car and the comfort of driving it. From that time on, pneumatic tires gradually came into use, and all cars began to be equipped with them. The winner of these races was again Levassor. When he stopped the car at the finish line and stepped onto the ground, he said: “It was crazy. I was doing 30 kilometers per hour!” Now at the finish site there is a monument in honor of this significant victory.

Eighth place - Light bulb

In the last decades of the 19th century, electric lighting entered the life of many European cities. Having first appeared on the streets and squares, it very soon penetrated into every house, into every apartment and became an integral part of the life of every civilized person. This was one of the most important events in the history of technology, which had enormous and varied consequences. The rapid development of electric lighting led to mass electrification, a revolution in the energy sector and major shifts in industry. However, all this might not have happened if, through the efforts of many inventors, such a common and familiar device as the light bulb had not been created. Among the greatest discoveries of human history, it undoubtedly holds one of the most honorable places.

In the 19th century, two types of electric lamps became widespread: incandescent and arc lamps. Arc lights appeared a little earlier. Their glow is based on such an interesting phenomenon as a voltaic arc. If you take two wires, connect them to a sufficiently strong current source, connect them, and then move them apart a few millimeters, then between the ends of the conductors something like a flame with a bright light will form. The phenomenon will be more beautiful and brighter if, instead of metal wires, you take two sharpened carbon rods. When the voltage between them is high enough, a light of blinding intensity is formed.

The phenomenon of a voltaic arc was first observed in 1803 by the Russian scientist Vasily Petrov. In 1810, the same discovery was made by the English physicist Devi. Both of them produced a voltaic arc using a large battery of cells between the ends of charcoal rods. Both of them wrote that the voltaic arc can be used for lighting purposes. But first it was necessary to find a more suitable material for the electrodes, since charcoal rods burned out in a few minutes and were of little use for practical use. Arc lamps also had another inconvenience - as the electrodes burned out, it was necessary to constantly move them towards each other. As soon as the distance between them exceeded a certain permissible minimum, the light of the lamp became uneven, it began to flicker and went out.

The first arc lamp with manual adjustment of the arc length was designed in 1844 by the French physicist Foucault. He replaced charcoal with sticks of hard coke. In 1848, he first used an arc lamp to illuminate one of the Parisian squares. It was a short and very expensive experiment, since the source of electricity was a powerful battery. Then various devices were invented, controlled by a clock mechanism, which automatically moved the electrodes as they burned.
It is clear that from the point of view of practical use, it was desirable to have a lamp that was not complicated by additional mechanisms. But was it possible to do without them? It turned out that yes. If you place two coals not opposite each other, but in parallel, so that an arc can form only between their two ends, then with this device the distance between the ends of the coals always remains unchanged. The design of such a lamp seems very simple, but its creation required great ingenuity. It was invented in 1876 by the Russian electrical engineer Yablochkov, who worked in Paris in the workshop of academician Breguet.

In 1879, the famous American inventor Edison took up the task of improving the light bulb. He understood: in order for the light bulb to shine brightly and for a long time and have an even, unblinking light, it is necessary, firstly, to find a suitable material for the filament, and, secondly, to learn how to create a very rarefied space in the cylinder. Many experiments were carried out with various materials, which were carried out on a scale characteristic of Edison. It is estimated that his assistants tested at least 6,000 different substances and compounds, and over 100 thousand dollars were spent on experiments. First, Edison replaced the brittle paper charcoal with a stronger one made from coal, then he began to experiment with various metals and finally settled on a thread of charred bamboo fibers. That same year, in the presence of three thousand people, Edison publicly demonstrated his electric light bulbs, illuminating his home, laboratory, and several surrounding streets with them. It was the first long-life light bulb suitable for mass production.

penultimate, ninth place in our top 10 occupy Antibiotics, and in particular - penicillin

Antibiotics are one of the most remarkable inventions of the 20th century in the field of medicine. Modern people are not always aware of how much they owe to these medicinal drugs. Humanity in general very quickly gets used to the amazing achievements of its science, and sometimes it takes some effort to imagine life as it was, for example, before the invention of television, radio or steam locomotive. Just as quickly, a huge family of various antibiotics entered our lives, the first of which was penicillin.

Today it seems surprising to us that back in the 30s of the 20th century, tens of thousands of people died annually from dysentery, that pneumonia in many cases was fatal, that sepsis was a real scourge of all surgical patients, who died in large numbers from blood poisoning, that typhus was considered a most dangerous and intractable disease, and pneumonic plague inevitably led the patient to death. All these terrible diseases (and many others that were previously incurable, such as tuberculosis) were defeated by antibiotics.

Even more striking is the impact of these drugs on military medicine. It’s hard to believe, but in previous wars, most soldiers died not from bullets and shrapnel, but from purulent infections caused by wounds. It is known that in the space around us there are myriads of microscopic organisms, microbes, among which there are many dangerous pathogens.

Under normal conditions, our skin prevents them from penetrating into the body. But during the wound, dirt entered the open wounds along with millions of putrefactive bacteria (cocci). They began to multiply with colossal speed, penetrated deep into the tissues, and after a few hours no surgeon could save the person: the wound festered, the temperature rose, sepsis or gangrene began. The person died not so much from the wound itself, but from wound complications. Medicine was powerless against them. In the best case, the doctor managed to amputate the affected organ and thereby stopped the spread of the disease.

To combat wound complications, it was necessary to learn to paralyze the microbes that cause these complications, to learn to neutralize the cocci that got into the wound. But how to achieve this? It turned out that you can fight microorganisms directly with their help, since some microorganisms, in the course of their life activity, release substances that can destroy other microorganisms. The idea of using microbes to fight germs dates back to the 19th century. Thus, Louis Pasteur discovered that anthrax bacilli are killed by the action of certain other microbes. But it is clear that resolving this problem required enormous work.

Over time, after a series of experiments and discoveries, penicillin was created. Penicillin seemed like a real miracle to seasoned field surgeons. He cured even the most seriously ill patients who were already suffering from blood poisoning or pneumonia. The creation of penicillin turned out to be one of the most important discoveries in the history of medicine and gave a huge impetus to its further development.

And lastly, tenth place ranked in survey results Sail and ship

It is believed that the prototype of the sail appeared in ancient times, when people just started building boats and ventured out to sea. In the beginning, simply stretched animal skin served as a sail. The person standing in the boat had to hold and orient it relative to the wind with both hands. It is unknown when people came up with the idea of strengthening the sail with the help of a mast and yards, but already on the oldest images of the ships of the Egyptian queen Hatshepsut that have come down to us, one can see wooden masts and yards, as well as stays (cables that keep the mast from falling back), halyards (lifting gear and lowering sails) and other rigging.

Consequently, the appearance of a sailing ship must be attributed to prehistoric times.

There is much evidence that the first large sailing ships appeared in Egypt, and the Nile was the first high-water river on which river navigation began to develop. Every year from July to November, the mighty river overflowed its banks, flooding the entire country with its waters. Villages and cities found themselves cut off from each other like islands. Therefore, ships were a vital necessity for the Egyptians. They played a much greater role in the economic life of the country and in communication between people than wheeled carts.

One of the earliest types of Egyptian ships, which appeared about 5 thousand years BC, was the barque. It is known to modern scientists from several models installed in ancient temples. Since Egypt is very poor in timber, papyrus was widely used for the construction of the first ships. The features of this material determined the design and shape of ancient Egyptian ships. It was a sickle-shaped boat, knitted from bundles of papyrus, with bow and stern curved upward. To give the ship strength, the hull was tightened with cables. Later, when regular trade with the Phoenicians was established and large quantities of Lebanese cedar began to arrive in Egypt, the tree began to be widely used in shipbuilding.

An idea of what types of ships were built then is given by the wall reliefs of the necropolis near Saqqara, dating back to the middle of the 3rd millennium BC. These compositions realistically depict the individual stages of the construction of a plank ship. The hulls of ships, which had neither a keel (in ancient times it was a beam lying at the base of the ship’s bottom) nor frames (transverse curved beams that ensured the strength of the sides and bottom), were assembled from simple dies and caulked with papyrus. The hull was strengthened by means of ropes that covered the ship along the perimeter of the upper plating belt. Such ships hardly had good seaworthiness. However, they were quite suitable for river navigation. The straight sail used by the Egyptians allowed them to sail only with the wind. The rigging was attached to a two-legged mast, both legs of which were installed perpendicular to the centerline of the ship. At the top they were tightly tied. The step (socket) for the mast was a beam device in the hull of the ship. In the working position, this mast was held by stays - thick cables running from the stern and bow, and it was supported by legs towards the sides. The rectangular sail was attached to two yards. When there was a side wind, the mast was hastily removed.

Later, around 2600 BC, the two-legged mast was replaced by the one-legged one that is still in use today. The single-legged mast made sailing easier and gave the ship the ability to maneuver for the first time. However, the rectangular sail was an unreliable means that could only be used with a fair wind.

The main engine of the ship remained the muscular power of the rowers. Apparently, the Egyptians were responsible for an important improvement in the oar - the invention of rowlocks. They did not yet exist in the Old Kingdom, but then they began to attach the oar using rope loops. This immediately made it possible to increase the stroke force and speed of the vessel. It is known that selected rowers on the ships of the pharaohs made 26 strokes per minute, which allowed them to reach a speed of 12 km/h. Such ships were steered using two steering oars located at the stern. Later they began to be attached to a beam on the deck, by rotating which it was possible to select the desired direction (this principle of steering a ship by turning the rudder blade remains unchanged to this day). The ancient Egyptians were not good sailors. They did not dare to go out to the open sea with their ships. However, along the coast, their trading ships made long journeys. Thus, in the temple of Queen Hatshepsut there is an inscription reporting on the sea voyage carried out by the Egyptians around 1490 BC. to the mysterious land of incense Punt, located in the region of modern Somalia.

The next step in the development of shipbuilding was taken by the Phoenicians. Unlike the Egyptians, the Phoenicians had an abundance of excellent building materials for their ships. Their country stretched in a narrow strip along the eastern shores of the Mediterranean Sea. Vast cedar forests grew here almost right next to the shore. Already in ancient times, the Phoenicians learned to make high-quality dugout single-shaft boats from their trunks and boldly went to sea with them.

At the beginning of the 3rd millennium BC, when maritime trade began to develop, the Phoenicians began to build ships. A sea vessel is significantly different from a boat; its construction requires its own design solutions. The most important discoveries along this path, which determined the entire subsequent history of shipbuilding, belonged to the Phoenicians. Perhaps the skeletons of animals gave them the idea to install stiffening ribs on single-tree poles, which were covered with boards on top. Thus, for the first time in the history of shipbuilding, frames were used, which are still widely used.

In the same way, the Phoenicians were the first to build a keel ship (initially, two trunks connected at an angle served as the keel). The keel immediately gave the hull stability and made it possible to establish longitudinal and transverse connections. Sheathing boards were attached to them. All these innovations were the decisive basis for the rapid development of shipbuilding and determined the appearance of all subsequent ships.

Other inventions in various fields of science were also recalled, such as chemistry, physics, medicine, education and others.
After all, as we said earlier, this is not surprising. After all, any discovery or invention is another step into the future, which improves our lives, and often prolongs it. And if not every, then very, very many discoveries deserve to be called great and extremely necessary in our lives.

Alexander Ozerov, based on the book by Ryzhkov K.V. "One Hundred Great Inventions"

We live in unique times! It only takes half a day to fly halfway around the Earth, our super-powerful smartphones are 60,000 times lighter than the original computers, and today's agricultural production and life expectancy are the highest in human history!

We owe these enormous achievements to a small number of great minds - scientists, inventors and artisans who conceived and developed the products and machines on which the modern world is built. Without these people and their incredible inventions, we would go to bed at sunset and be stuck in a time before cars and telephones.

In this list, we will talk about the most important and decisive recent inventions, their history and significance in the development of mankind. Can you guess which inventions we'll be talking about?

From methods for sanitizing food and making food safer, to a toxic gas that helped form the basis of international trade, to an invention that led to the sexual revolution and liberated people, each of these creations had a direct impact on people's lives. Find out about 25 outstanding inventions that changed our world!

25. Cyanide

While cyanide is a rather grim way to start this list, this chemical has played an important role in human history. While its gaseous form has caused the death of millions of people, cyanide serves as the main factor in extracting gold and silver from ore. And since the world economy was tied to the gold standard, cyanide served and continues to be an important factor in the development of international trade.

24. Airplane

There is no doubt in anyone's mind that the invention of the “iron bird” had one of the greatest influences on human history.

Radically reducing the time needed to transport people and cargo, the airplane was invented by the Wright brothers, who built on the work of previous inventors such as George Cayley and Otto Lilienthal.

Their invention was readily accepted by a significant part of society, after which the “golden age” of aviation began.

23. Anesthesia

Before 1846, there was little difference between surgical procedures and painful experimental torture.

Anesthetics have been used for thousands of years, although their early forms were much simplified versions, such as alcohol or mandrake extract.

The invention of modern anesthesia in the form of nitrous oxide (“laughing gas”) and ether allowed doctors to perform operations without fear of causing pain to patients. (Bonus fact: Cocaine is said to have become the first effective form of local anesthesia after it was used in eye surgery in 1884.)

22. Radio

The history of the invention of radio is not so clear: some claim that it was invented by Guglielmo Marconi, others insist that it was Nikola Tesla. In any case, these two men relied on the work of many famous predecessors before successfully transmitting information via radio waves.

And while this is commonplace today, try to imagine telling someone in 1896 that you could transmit information through the air. You would be mistaken for insane or possessed by demons!

21. Telephone

The telephone has become one of the most important inventions of the modern world. As with most great inventions, its inventor and the people who made significant contributions to its creation are hotly debated and debated to this day.

The only thing that is known for certain is that the first patent for a telephone was issued by the US Patent Office to Alexander Graham Bell in 1876. This patent served as the basis for further research and development of electronic sound transmission over long distances.

20. “World Wide Web, or WWW

Although most of us assume that this invention is recent, the Internet has actually existed in its outdated form since 1969, when the US military developed the ARPANET (Advanced Research Project Agency Network).

The first message that was planned to be sent over the Internet - “log in” - crashed the system, so only “lo” could be sent. The World Wide Web as we know it today began when Tim Berners-Lee created the hypertext document network and the University of Illinois created the first Mosaic browser.

19. Transistor

It seems like there's nothing easier than picking up the phone and contacting someone in Bali, India or Iceland, but it wouldn't work without a transistor.

Thanks to this semiconductor triode, which amplifies electrical signals, it became possible to transmit information over vast distances. The man who co-invented the transistor, William Shockley, founded the laboratory that pioneered the creation of Silicon Valley.

18. Quantum clocks

While it may not seem as revolutionary as many of the things listed previously, the invention of quantum (atomic) clocks was crucial to the development of humanity.

Using microwave signals emitted by the changing energy levels of electrons, quantum clocks and their precision have made possible a wide range of modern inventions, including GPS, GLONASS and the Internet.

17. Steam turbine

Charles Parsons' steam turbine pushed the boundaries of human technological progress, powering industrialized nations and enabling ships to cross vast oceans.

The engines operate by rotating a shaft using compressed water steam, which generates electricity - one of the main differences between a steam turbine and a steam engine, which revolutionized the industry. In 1996 alone, 90% of all electricity generated in the United States was generated by steam turbines.

16. Plastic

Despite its widespread use in modern society, plastic is a relatively recent invention, appearing only over a hundred years ago.

This moisture-resistant and incredibly pliable material is used in almost every industry - from food packaging to toy production and even spacecraft.

Although most modern plastics are made from petroleum, there are growing calls for a return to the original version, which was partly natural and organic.

15. Television

Television has a long and storied history that began in the 1920s and is still evolving today, through to the advent of modern capabilities such as DVDs and plasma panels.

One of the most popular consumer products around the world (nearly 80% of households own at least one television), this invention was the cumulative result of numerous previous advances to create a product that became a major influencer of public opinion in the mid-20th century.

14. Oil

Most of us don't think twice about filling up our car's gas tank. Although humanity has been producing oil for thousands of years, the modern gas and oil industry began its development in the second half of the 19th century - after modern streetlights appeared on the streets.

Having appreciated the enormous amount of energy that is generated by burning oil, industrialists rushed to build wells to extract “liquid gold.”

13. Internal combustion engine

Without productive oil, there would be no modern internal combustion engine.

Used in many areas of human activity - from cars to agricultural combines and excavators - internal combustion engines make it possible to replace people with machines that can perform back-breaking, painstaking and time-consuming work in a matter of time.

Also, thanks to these engines, people gained freedom of movement, as they were used in the original self-propelled vehicles (cars).

12. Reinforced concrete

Before the advent of reinforced concrete in the mid-19th century, humanity could safely erect buildings only up to a certain height.

Embedding steel reinforcing bars before pouring concrete strengthens it so that man-made structures can now support much more weight, allowing us to build larger and taller buildings and structures than ever before.

11. Penicillin

There would be far fewer people on our planet today if it were not for penicillin.

Officially discovered by Scottish scientist Alexander Fleming in 1928, penicillin became one of the most significant inventions (or discoveries, to a large extent) that made our modern world possible.

Antibiotics were among the first drugs that could properly treat staphylococcus, syphilis and tuberculosis.

10. Cooling

Taming fire was perhaps humanity's most important discovery to date, but it would take millennia until we tamed cold.

Although humanity has long used ice for cooling, its practicality and availability have been limited for some time. In the 19th century, humanity made significant progress in its development after scientists invented artificial cooling using chemical elements that absorb heat.

By the early 1900s, nearly every meatpacking plant and large wholesaler used refrigeration to store food.

9. Pasteurization

Helping to save many lives half a century before the discovery of penicillin, Louis Pasteur invented the process of pasteurizing, or heating foods (originally beer, wine and dairy products) to a temperature high enough to kill most bacteria that cause putrefaction.

Unlike sterilization, which kills all bacteria, pasteurization, while preserving the taste of the product, reduces the number of potential pathogens only, reducing it to a level at which they are not capable of causing harm to health.

8. Solar battery

Just as oil fueled industry, the invention of the solar cell has allowed us to use renewable energy in a much more efficient way.

The first practical solar battery was developed in 1954 by specialists from the Bell Telephone laboratory based on silicon. Over the years, the efficiency of solar panels has increased dramatically along with their popularity.

7. Microprocessor

If the microprocessor had not been invented, we would never have known about laptops and smartphones.

One of the most widely known supercomputers, ENIAC, was created in 1946 and weighed 27,215 kg. Intel electronics engineer and global hero Ted Hoff developed the first microprocessor in 1971, packing the functions of a supercomputer into one small chip, making portable computers possible.

6. Laser

An acronym for “Light Amplification by Stimulated Emission of Radiation,” the laser was invented in 1960 by Theodore Maiman. The amplified light is anchored through spatial coherence, allowing the light to remain focused and concentrated over long distances.

In today's world, lasers are used almost everywhere, including laser cutting machines, barcode scanners and surgical equipment.

5. Nitrogen fixation (nitrogen fixation)

Although the term may seem overly scientific, nitrogen fixation is actually responsible for the dramatic increase in human population on Earth.

By converting atmospheric nitrogen into ammonia, we have learned to produce highly effective fertilizers, which have made it possible to increase production on the same plots of land, significantly improving our agricultural products.

4. Assembly line

The impact of commonplace inventions in their time is rarely remembered, but the importance of the assembly line cannot be overstated.

Before his invention, all products were painstakingly made by hand. The assembly line made it possible to create mass production of identical components, significantly reducing the time to manufacture a new product.

3. Birth control pill

Although pills and tablets have been one of the main methods of taking medicine for thousands of years, the invention of the birth control pill was the most revolutionary of them all.

Approved for use in 1960 and now taken by more than 100 million women worldwide, this combined oral contraceptive was a major impetus for the sexual revolution and changed the conversation about fertility, largely shifting the responsibility of choice from men to women.

2. Mobile phone/smartphone

Chances are, you're reading or viewing this list on your smartphone right now.

Although the first widely known smartphone was the iPhone, which hit the market in 2007, we have Motorola, its “ancient” predecessor, to thank for that. In 1973, it was this company that released the first wireless pocket mobile phone, which weighed 2 kilograms and charged for 10 hours.
