The most important inventions of the 20th century list. Twelve greatest inventions of the 20th century. The twentieth century was primarily a century of technology. Five of the great achievements noted by France Press relate to

The 20th century was rich in all kinds of discoveries and inventions, which in some ways improved and in others complicated our lives. However, if you think about it, there have not been many inventions that have truly changed this world. We have collected some of the very best inventions, after which life will never be the same.

20th century inventions that changed the world

Aircraft

People made the first flights on lighter-than-air vehicles (aeronautics) back in the 18th century, it was then that the first balloons filled with hot air appeared, with the help of which it was possible to fulfill the long-standing dream of mankind - to rise into the air and soar in it. However, due to the impossibility of controlling the direction of flight, dependence on weather and low speed, the hot air balloon in many ways did not suit humanity as a means of transport.

The first controlled flights on heavier-than-air vehicles occurred at the very beginning of the 20th century, when the Wright brothers and Alberto Santos-Dumont independently experimented with light gliders equipped with motors. It was these aircraft that became the prototype of passenger airliners, which over the decades connected countries and continents and allowed the world to become truly global, significantly speeding up the movement of passengers over long distances and becoming one of the most important inventions of the 20th century.

Antibiotics

In 1928, Alexander Fleming discovered that samples contaminated with the common green mold Penicillium , Colonies of staphylococcus bacteria do not develop. It became obvious that the fungus secretes a substance that has a detrimental effect on bacterial cells. This accidental discovery, made in the 20th century, became one of the most significant in the history of medicine, as it helped to isolate first penicillin (1938), and then other antibiotic substances, with the help of which deadly bacterial diseases were cured.

Unfortunately, the advent of antibiotics also brought with it some negative consequences that also changed the world. The widespread and not always justified use of antibiotics leads to the fact that known bacteria mutate, taking on forms that are resistant to drugs. This phenomenon poses a danger to humanity because it complicates the treatment of bacteria infected with resistant forms and requires lengthy and expensive research to find new antibiotics.

Nuclear weapon

In August 1945, the most powerful explosions in the history of the planet were heard in the cities of Hiroshima and Nagasaki: the United States of America tested the first nuclear weapon, opening a new page in the history of means of destruction. Long years of studying radioactive materials have borne fruit; humanity has managed to split the atom and obtain a source of energy with colossal destructive power. In 1949, nuclear weapons were tested for the first time by the Soviet Union. In subsequent years, Great Britain, France, China, India, Pakistan and North Korea joined the “nuclear club.” The emergence of nuclear weapons and the very rapid increase in their number during the Cold War marked the beginning of a new era - from now on, humanity could virtually destroy the planet in a matter of hours, turning it into a desert uninhabitable for most organisms.

However, despite all the potential danger of a new type of weapon, many researchers believe that its presence rather played a positive role in the history of the planet, since since its appearance, members of the nuclear club have never waged large-scale wars among themselves. The most dangerous weapon on the planet has become a kind of insurance against military conflicts, because now “everyone will lose” in it. This factor will be the most powerful deterrent argument in all conceivable international conflicts for many years to come.

Semiconductor electronics

For a long time, one of the main components of electronic devices were vacuum tubes, the use of which significantly limited the capabilities of technology: the tubes took a long time to heat up to reach operating parameters, were large in size, had low reliability and very high heat generation.

Work on the development of devices based on semiconductor elements began in the 1920s, but for a long time their use was not widespread. Even during the Second World War, when the needs for computers and radio stations were greater than ever, they were still manufactured primarily on a tube basis. The first bipolar transistor was created in 1947, and the first MOS transistor, which forms the basis of all modern electronics, was created in 1960. Both types of transistors were based on semiconductors, which opened up almost limitless possibilities for improving electronics and microprocessors. Today, almost any household appliance, even a battery-powered children's railway or mixer, has a microcircuit inside its housing based on semiconductor elements. And for all electronic and computing devices, from calculators to laptops, semiconductor elements form the basis of the design. The performance of the elements of a modern audio player or TV (not to mention smartphones or computers) far exceeds the tube-based computers that occupied several rooms in research laboratories half a century ago.

Spacecraft

The first spacecraft, an artificial Earth satellite, was successfully launched in 1957, approximately 25 years after the start of the Soviet space program. From that moment on, man began to explore not only the planet, but also the nearest outer space. 4 years later, Yuri Gagarin, the first cosmonaut in human history, became a hero of the whole world. Human spaceflight and the visit to the moon (first accomplished by US astronauts in 1969) are considered among the most significant achievements of mankind.

In addition to the invaluable contribution to science made by the space programs of the USSR, the USA and some other countries, the launch of spacecraft forever changed many areas of the lives of ordinary people. Satellite Internet, INMARSAT communications, GPS navigation, Google Maps photographs, images of celestial objects from the Hubble telescope, weather forecasts - this is just an incomplete list of what we owe to one of the greatest inventions of the 20th century - the spacecraft launched by man.

Internet

The birthday of the Internet is considered to be October 29, 1969, when a communication session was held between the first two nodes of the ARPANET network, located at a distance of 640 km - at the University of California Los Angeles (UCLA) and at the Stanford Research Institute (SRI). Within 4 years, thanks to the transatlantic cable, the network became international, connecting the USA, Great Britain and Norway.

Today it is difficult to overestimate the importance of the World Wide Web. Today, the number of people regularly using the Internet reaches 2.5 billion people. Another proof that thanks to her the world has changed beyond recognition is that today the largest companies in the world are not railway monopolies, oil giants, automakers and banks, but IT corporations like Apple, Google and Microsoft, which are still 40 years away no one heard back.

The first tests of aircraft took place in the 18th century, but they were not very effective due to the lack of engines and the possibility of precise control.

With the invention of the steam locomotive in the 19th century, a new stage in the development of transport began. At the beginning of the 20th century, the main task was to create a controlled aircraft. And the inventors, the Wright brothers, succeeded in this - in 1903 they made the first flight in history for a vehicle with an engine. But that was only the beginning of the story. In 1907, the prototype of a helicopter was created - the first aircraft with rotating blades. In turn, the controlled one was first tested in Germany in 1936. At the end of the Second World War, the next speed limit was overcome - an aircraft with a jet engine was tested.

The fifties became the time. The first unmanned spacecraft was invented and designed in the USSR. And in 1961, the first person got into it - spacecraft became manned.

Means of communication

Not only the movement of people in space has accelerated, but also the transfer of information. In particular, the invention of television was an important milestone. The topic of transmitting images over a distance was of interest to scientists back in the 19th century, but the practical implementation of this project dates back to the twenties of the 20th century. In the thirties, the first regular television broadcasting began - in 1934, the first television viewers saw programs in Great Britain and Germany.

Historians of science usually do not name the inventor of the television, since both television broadcasting and the television apparatus itself were developed by several specialists, among whom was a native of Russia, Vladimir Zvorykin.

The breakthrough of the second half of the 20th century was the invention of the computer and the Internet. In the eighties, the World Wide Web began to spread more and more among private users, and in modern developed countries the number of Internet users is approaching 100%.

Medicine

The 20th century was a turning point for medical science. During World War II, penicillin was introduced into use, the first antibiotic that saved millions of lives. Revolutionary diagnostic methods were created - thanks to ultrasound and MRI machines, it became possible to identify dangerous diseases in the early stages. Although full-fledged artificial organs have not yet been created, many patients with heart failure are helped by the invention of the 20th century - the pacemaker. Thanks to these discoveries, the average life expectancy has increased significantly - a person born in developed countries has every chance of living more than 80 years.

Twelve
greatest inventions of the 20th century

The twentieth century was primarily a century of technology. Five of the great achievements noted by France Press are in the field of medicine and biology. Seven - to physics and technology: aviation, television, nuclear fission, computer, laser, space flights and the Internet.

Aviation
In 1903, bicycle manufacturers the Wright brothers made the first ever powered flight. In 1930, British engineer Frank Whittle registered a patent for a jet engine. As a result of independent research, in 1939 the German company Heinkel created the first jet aircraft, the He-178.

Unraveling the genetic code of humans, animals and plants has made it possible to increase resistance to disease and improve the quality of food. In the coming decades, humanity is expected to gain the ability to gene therapy for cancer, heart disease, hemophilia, diabetes and many other dangerous diseases.

Laser
This device is based on the theory of radiation stimulation, formulated by Albert Einstein back in 1917. But it took 40 years before Gordon Gould, a doctoral student at New York's Columbia University, turned the idea into reality. The discovery embroiled Gould in a 30-year battle over patent priority. Meanwhile, his discovery has found countless applications, from welding and medicine to computers and video.

Organ transplantation
The key date is 1967, when South African doctor Christian Barnard performed the world's first human heart transplant. As related branches of medicine developed, reducing the rejection of transplants, doctors mastered the replacement of hands, intestines, skin, retinas and even testicles. Today on the agenda is a brain cell transplant, which will cure Alzheimer's and Parkinson's diseases, and “xenotransplantation” - the transplantation of animal organs into humans.

Test tube baby
Louise Brown turned 21 this year. A young Englishwoman became history's first "test tube baby" - grown from an egg removed from the mother's body and fertilized. This technology has given many previously childless families hope for procreation.

Space flights
The space age began on October 4, 1957 with the launch of the first Soviet satellite. The first person in space was Soviet citizen Yuri Gagarin in 1961. In 1969, American astronauts landed on the surface of the Moon. Later, Western European countries, China and Japan made spacewalks.
Today, satellites are used to establish cheap and high-quality telephone communications, television and data transmission. And also for navigation, weather forecasting and obtaining scientific data. Unmanned vehicles travel to other planets. In the near future, it is planned to create long-term habitable stations in low-Earth orbit.

Internet
In 1969, the world's first transfer of switched data packets between two remote computers was carried out in Southern California. The Pentagon's secret project became a worldwide social and cultural phenomenon thanks to the easy-to-use and intuitively transparent ideology of hyperlinks and transitions without a single central database, developed in 1989 by the British Tim Bernes-Lee.
Today the number of Internet users has reached 183 million; by 2003, according to some estimates, it may exceed a billion.

The list, as you can see, is quite impressive. The people of the 20th century did not waste the 100 years allotted to them in vain. And yet, the main discovery of the second millennium occurred long before our century. The inventor of printing, Johannes Gutenberg, is recognized as the Man of the Millennium. However, this is not the opinion of France Press, but of the Sunday Times.

To paraphrase the classic - if ballpoint pens did not exist, they would have to be invented. All the convenience of a ballpoint pen can be fully appreciated only by those who have had the opportunity to write with fountain pens and liquid pens.

With the arrival of ballpoint pens on the stationery market, schoolchildren could breathe a sigh of relief. Blots, blotters, notebooks covered in ink, smeared hands and face are a thing of the past. After all, previously the student’s task was not so much learning to write, but the ability to handle pens and inkwells.

The advent of ballpoint pens

The main inconvenience of fountain pens and liquid pens was the need to regularly wet the pen with ink, which was still acceptable at school, but significantly slowed down any processes in the adult world - from political to industrial. A special need for transformation was observed where pilots were forced to use pencils. The idea of ​​a permanent supply of ink to the writing unit of the pen was considered by inventors for a long time. The first analogs of a pen with a ball built into the writing tip were discovered on the territory of modern Armenia in a drawing dated 1166. Subsequently, the idea of ​​a rotating tip was returned to repeatedly - 350 patents were issued in the USA alone. But the official inventors are the American John D. Loud and the Hungarians Laszlo and Georg Biro, who patented non-leak handles.

The idea to organize our own production of ballpoint pens in the Soviet Union arose in 1949. It was not in the traditions of the Soviet state to purchase patents, especially for public consumption. Therefore, based on the best world samples, domestic copies were created. The production of ballpoint pens was carried out by local industrial enterprises and industrial cooperation. The quality of the product was so low that the appearance of the first ballpoint pens passed without a stir. The problem was the poor design of the writing unit. The complex procedure for refilling the balloon again created inconveniences - a ball was removed from the tip, a new portion of ink was pumped through the resulting hole with a syringe, and the ball was rolled back into the sphere. There were even stationary refill points. The quality of the ink, for the production of which they began to use a mixture of castor oil and rosin, left much to be desired. At that time, the Union did not have the technological capabilities to eliminate these shortcomings, the pens ceased to be in demand and were no longer produced. The production of ballpoint pens resumed in 1965 at the Kuibyshev Ball Bearing Plant. Then Swiss equipment was purchased for the production of writing units and it was possible to find out the recipe for Parker ink. However, the introduction of ballpoint pens into mass culture occurred in the early 70s. The popularization of the model was hampered by educational standards, according to which great importance was attached to the formation of handwriting. The technical capabilities of a ballpoint pen did not make it possible to implement the requirements for “writing out” letters that existed at that time. For a long time, the problem was the issue of components - replacing a covered refill was extremely difficult, you had to buy a new one. But with the solution of these issues, a design boom for ballpoint pens began in the Union. Sets of colored pens, automatic, two-, four-, and six-color ballpoint pens began to be produced. Interesting fact: among the Kremlin leaders, M.S. was the first to sign documents with a Parker ballpoint pen. Gorbachev. Previous leaders preferred either pencils or solid ink devices.

The principle of a ballpoint pen is quite simple - at its end there is a small ball that rolls along the surface of the paper and leaves behind traces of ink that seeps into a small gap between the walls. But this invention was made not so long ago - in 1888, and the pen became widespread only in the 20th century, after the creation of the modern model.

History of the invention of the ballpoint pen

Until the end of the 19th century, all writing instruments that used ink required constant dipping into the inkwell. It was inconvenient to write, it took a long time, and there were ugly blots on the paper. Engineers began to think about how to make a pen with ink supply. In 1888, American engineer John Loud patented the principle of a pen with a special reservoir for ink, which was fed through thin channels to a tip with a round hole. There was no ball in the small hole at the end of the pen yet, but this device already made it possible to write on paper without dipping it into ink. Although this pen was far from perfect: it also made blots, although less often than feathers.
In 1938, a Hungarian journalist named Biro invented a modern ballpoint pen: first of all, he placed a small ball in a hole that allowed ink to be retained and prevent blots from getting in, and also made writing more enjoyable. In addition, Biro made special ink for such pens - while watching newspapers being printed, he noticed that the ink on them dried out much faster. True, they were too thick to use in a pen, but he perfected their formula.

History of the development of the ballpoint pen

A lot of time has passed since the advent of the modern design of a ballpoint pen - more than seventy years, but its principle and structure have hardly changed. Even the very first such pens had excellent characteristics, and most importantly, they were distinguished by a large supply of ink and low ink consumption.
The first buyers of ballpoint pens were pilots - for them it was important that the writing instrument did not “leak”, since at high altitudes this was a common phenomenon: the pressure in the air is higher.
The first ballpoint pens appeared in the Soviet Union after World War II. Soviet engineers had to make the ink themselves, since the owner of the company that produced the most famous Parker pens refused to cooperate with Stalin. Production of the pens began in 1949, but they were too expensive for widespread distribution.
It wasn't until 1958 that ballpoint pens dropped in price enough to become widely used. In 1965, they began to be produced using Swiss equipment, and soon the pens began to be issued in schools. Soon this product became one of the most popular; today most handles have this design.

First controllable aircraft

In December 1903, the first controllable aircraft was created by the Wright brothers, called Flyer 1. It was not the first aircraft in history, but its main feature was the developed new theory of flight “on three axes of rotation.” It was this theory that allowed aircraft manufacturing to develop further, focusing the attention of scientists not on the installation of more powerful parts, but on the efficiency of their use. Flyer 1 stayed in the air for almost a minute, flying 260 meters.

Computer

The invention of the computer and the first full-fledged programming language is credited to the German engineer Konrad Zuse. The first fully functional computer was presented to the public in 1941 and was called the Z3. It should be noted that the Z3 had all the properties that computers have today.
After the war, the Z3, like its predecessors, was destroyed. However, its successor Z4 survived, from which sales of computers began.

Internet

Initially, the Internet was conceived by the US Department of Defense as a reliable channel for transmitting information in case war broke out. Several research centers were commissioned to develop the first network, which eventually were able to create the first Arpanet server. Over time, the server began to grow, and more and more scientists connected to it to exchange information.
The first remote connection (at a distance of 640 km) was made by Charlie Cline and Billy Duvalley. This happened in 1969 - this day is considered the birthday of the Internet. After this operation, the sphere began to develop at tremendous speed. In 1971, a program for sending email was developed, and in 1973 the network became international.

Space exploration

The stumbling block in the 20th century in relations between the United States and the Soviet Union was developments in space exploration. The first artificial satellite was launched by the USSR on October 4, 1957.
The first scientist who put forward the idea of ​​​​creating a rocket traveling between planets was K. Tsiolkovsky. By 1903, he managed to design it. The main thing in his development was the formula he created for the speed of an aircraft, which is used to this day in rocket science.
The first vehicle to go into space was the V-2 rocket, launched in the summer of 1944. It was this event that laid the foundation for further accelerated development, demonstrating the great capabilities of missiles.

Inventions of the 20th century that changed our lives

Since ancient times, people have tried to make dreams and fantasies come true in order to simplify and diversify their life. We will list several inventions of the 20th century that changed the way we look at life.
1. X-rays

A KVN joke says that X-ray was invented by clerk Ivanov, who told his wife: “I can see right through you, bitch.” In fact, electromagnetic radiation was discovered at the end of the 19th century by the German physicist Wilhelm Roentgen. Having turned on the current in the cathode tube, the scientist noticed that a nearby paper screen covered with barium platinocyanide crystals was emitting a green glow. According to another version, the wife brought X-ray dinner, and when she put the plate on the table, the scientist noticed that her bones were visible through the skin. It is reliably known that Wilhelm for a long time refused to obtain a patent for an invention, not considering his research to be a full-fledged source of income. X-rays can easily be considered one of the discoveries of the 20th century.

2. Airplane

Since ancient times, people have tried to create a flying machine and rise above the earth. But only in 1903, the American inventors the Wright brothers managed to successfully test their Flyer 1, equipped with an engine. It was in the air for a full 59 seconds and flew 260 meters over the Kitty Hawk Valley. This event is considered the moment of the birth of aviation. Today, it is impossible to imagine either business development or recreation without airplanes. "Steel birds" are still the fastest mode of transport.

3. Television

Not so long ago, a television was considered a prestigious thing, emphasizing the status of the owner. At different times, many minds worked on its development. Back in the 19th century, Portuguese professor Adriano De Paiva and Russian inventor Porfiry Bakhmetyev independently put forward the idea of ​​the first device capable of transmitting images over wires. In 1907, Max Dieckmann demonstrated the first television receiver with a 3x3 screen. In the same year, Boris Rosing, a professor at the St. Petersburg Institute of Technology, proved the possibility of using a cathode ray tube to convert an electrical signal into a visible image. In 1908, Armenian physicist Hovhannes Adamyan received a patent for a two-color apparatus for transmitting signals. At the end of the 20s of the 20th century, the first television was developed in America, assembled by Russian emigrant Vladimir Zvorykin. He managed to split the light beam into blue, red and green colors and get a color image. He called his sample an “iconoscope.” However, in the West, the “father of television” is considered the Scotsman John Logie Bird, who patented a device that creates an image from eight lines.

19th century inventions

Inventions of the 19th and 20th centuries are very numerous. The most significant are photography, dynamite, and aniline dyes for fabrics. In addition, cheaper methods for producing paper and alcohol were discovered, and new medicines were invented.

Technical inventions of the 19th century were of great importance in the development of society. Thus, with the help of the telegraph, people were able to transmit messages within a few seconds from one end of the world to the other. The telegraph was invented in 1850. A little later, telegraph lines began to appear. Graham Bell invented the telephone. Today people cannot imagine life without this discovery.

Inventions of the 19th century from different countries of the world were brought to an exhibition in 1851 in England. About seventeen thousand exhibits were present. In subsequent years, other countries, following the example of England, also began to organize international exhibitions of the latest achievements.

Inventions of the 19th century became a powerful impetus for the development of chemistry, physics, and mathematics. A feature of this period was the widespread use of electricity. Scientists of that time were studying electromagnetic waves and their effect on various materials. Electricity also began to be used in medicine.

Michael Faraday noticed the phenomenon of electromagnetic induction, and James C. Maxwell developed the electromagnetic theory of light. Heinrich Hertz proved that electromagnetic waves exist.

Inventions of the 19th century in the fields of medicine and biology were no less significant than in other scientific fields. A great contribution to the development of these industries was made by: Robert Koch, who discovered the causative agent of tuberculosis, Louis Pasteur, who became one of the founders of microbiology and immunology, Claude Bernard, who laid the foundations of endocrinology. In the same century, the first X-ray image was obtained. French doctors Brissot and Lond saw a bullet in the patient's head.

There were also inventions in the field of Astronomy in the 19th century. This science began to develop rapidly in that era. Thus, a section of Astronomy appeared - Astrophysics, which studied the properties of celestial bodies.

Dmitry Mendeleev made a great contribution to the development of chemistry by discovering the Periodic Law, on the basis of which a table of chemical elements was created. He saw the table in a dream. Some predicted elements were subsequently discovered.

The beginning of the 19th century was marked by the development of mechanical engineering and industry. In 1804, a car powered by a steam engine was demonstrated. In the 19th century, the internal combustion engine was created. This contributed to the development of faster means of transportation: steamships, steam locomotives, cars.

In the 19th century, railways began to be built. The first was built in 1825 by Stephenson in England. By 1840, the length of all railways was about 7,700 km; at the end of the 19th century it was about 1,080,000 km.

It is believed that people began to use computers in the 20th century. However, their first prototypes were invented already in the previous century. The Frenchman Jacquard discovered a way to program a loom in 1804. The invention made it possible to control the thread using punched cards, which contained holes in certain places. Using these holes, thread was supposed to be applied to the fabric.

Invented at the end of the 18th century, lathes found widespread use in industry in the 19th century. The equipment successfully replaced manual labor, processing metal with high precision.

The 19th century is rightly called the century of the “industrial revolution”, railways and electricity. This century had a huge impact on the worldview and culture of mankind, changing its value system. The invention of electric lamps, radio, telephone, engine and many other discoveries revolutionized human life at that time.

The 20th century went down in history thanks to a large number of important events. During these hundred years, two world wars happened, man went into space, and the state for the first time announced the transition to a post-industrial society. All this would have been impossible without relevant discoveries in various fields of knowledge. They were the impetus for further development.

The most important discoveries

The first major discovery was penicillin. This molecule became the world's first antibiotic and saved the lives of millions of people during the war. In 1928, biologist Alexander Fleming noticed during an experiment that ordinary mold destroys bacteria. In 1938, two scientists who continued to work on the properties of penicillin were able to isolate its pure form, on the basis of which the substance was produced as a medicine. All this gave a huge impetus to medicine in the research and creation of new medicines, thanks to which doctors around the world can fight most diseases.
A discovery was made by Max Planck, which explained to the entire scientific world how energy behaves inside an atom. Based on these data, Einstein created quantum theory in 1905, and after him Niels Bohr was able to create the first model of the atom. This gave impetus to electronics, nuclear energy, the development of chemistry and physics. All scientists used these data in their discoveries. Thanks to this discovery, the world has become so high-tech.

Discoveries recently assessed

The third important discovery was made in 1936 by John Keynes. He developed the theory of self-regulation of a market economy. His books and the ideas put forward in them helped develop economics and created a classical school that is still taught in universities of higher education. Thanks to his work, macroeconomics emerged as an independent science.
The fourth important discovery was made in 1911 by Kamerling-Oness. He first introduced the concept of superconductivity. This is a state in which some materials may have zero resistance to electricity. The contribution of this discovery is that thanks to such materials it became possible to create strong magnetic fields, which are needed to create the conditions for numerous experiments. Thanks to the capabilities of conductivity, much smaller power lines are already being created. Superconductors are parts of most serious scientific equipment.
The fifth discovery was made in 1985, when it was possible to detect ozone holes that arise in the atmosphere due to the release of large amounts of freons. Restoring the ozone layer is very important to prevent large amounts of solar radiation from reaching the Earth. Reducing the amount of ozone affects the incidence of cancer and the life of animals and plants.
Thanks to this discovery, humanity has taken measures to reduce emissions of bromine- and chlorine-based freons and replace the substance with fluorine-containing freons. But the most important thing is that people are thinking about preserving the planet and how to avoid environmental destruction as a result of anthropogenic activities.

Medical inventions of the 20th century. Top 10 medical discoveries of the 20th century

What 10 medical discoveries revolutionized medicine? This is what our article is about. In general, there are many ratings of everything in the world on the website top10reiting.com. Many discoveries were made without any purpose, simply as an experiment, and in the future they played a significant role in saving people with dangerous diseases.

Penicillin

Consider such a strange drug as penicillin, which saves from severe protracted gangrene and pneumonia that could not be cured and was fatal. It was discovered by a British scientist, in which he contributed his negligence by not washing the test tube after the microbes he was studying. In the future, this played an important role, which led to the drug “Penicillin”, which was used as an antibiotic.

Let us now consider a very popular research such as DNA. Which did not save human destinies. This discovery was recognized by all scientists of the world, as English scientists created a molecule by collecting all the information about the DNA of all living creatures on earth, from bacteria to humans, and came to the common idea that the structure of cells is the same for everyone. They made a significant contribution to the development of genetics as such.

Organ transplant

Organ transplantation was unknown until the 20s; no one dared to carry out such a thing with a person, but a doctor from America decided to take a risk, who transplanted the kidney and liver of a living person into a living one, without having a fatal outcome.

A large-scale device such as ultrasound plays a big role in the present time, and all thanks to those waves that penetrate a person and mirror the process in the body. The initial origin of radioactivity and subsequent research through nuclear physics led to the development of radiobiology, from which came the change in ionizing radiation on living organisms.

Vacuum conception

Another name for in vitro conception, which facilitates fertility, the process is expensive and painstaking, its essence lies in the fact that the family of a healthy man is taken and placed in the woman’s uterus, where conception occurs under the supervision of a specialist doctor, the danger lies with the woman as rejection and such actions can occur will have to be interrupted, but in modern conditions such cases are unlikely.

Phacoemulsification

Destruction of the lens using vibration vibrations that destroy the nucleus. The advantage of this operation is that the incision is small, it is practically invisible. Operations often occur without complications, and another artificial lens is installed in place of the previous lens, which performs all the same functions as the natural one.

Prosthetics

Prosthetics. Medicine has stepped forward a great distance in the field of mechanics, namely, scientists created a prosthesis, an artificial part of the body, an organ by German scientists, thanks to his discoveries, many now have arms and legs, as well as hearts and eyes. But closer to the 21st century, prosthetics have become such that they cannot be distinguished from natural ones.

Immunology

Immunology has made its contribution to science, which helps to cope with viruses and diseases in the early stages and stopping them. Mechnikov has developed a serum that helps the body overcome the early stages.

A disease of unknown origin, which has not been discovered to this day, but helps to maintain a balance in life with the help of insulin, a hormone that lowers blood sugar thanks to beta cells. Back in 1969, they began to study this disease, but they could not find a solution to what the body still lacked to reduce sugar. In Toronto there was a development that was not the first stage, but with a final ending.

Vitaminology

The body is so fragile that it does not have time to fight many diseases; frequent illnesses, viruses, and a decline in immunity are associated with a lack of vitamins in the body. For the first time, the teachings of Resche came to this discovery and began to develop and combine vitamins of different groups. After conducting more than one study, he came to the division of vitamins into groups and made an immunological table.

Today, a parachute, designed for soft landings from high altitudes, has become a common item used all over the world. An object that is so familiar to everyone has come a long and interesting way through the centuries, acquiring a modern appearance.
The great Leonardo da Vinci, who became the author of many useful devices and mechanisms of Renaissance Italy, did not ignore the parachute, developing the design of a simple apparatus with a stretched dome area, approximately equal to the area of ​​the modern one. A design similar to a conical device is preserved in a 15th century manuscript. However, the ingenious invention remained only on paper.
Several decades later, the Italian Fausto Veranzio, impressed by da Vinci’s sketches, published the treatise “New Machines” in 1595. The treatise depicts a drawing of a man flying from a tower, suspended from a six-meter dome, attached at the edges to a wooden frame. In 1617, Veranzio made his dream come true by descending on a piece of square canvas from the bell tower of St. Mark's Basilica in Venice.

Achievements and losses

The following centuries revealed to the world several dozen inventors who contributed to the development of the parachute. Some died while testing their devices.

In 1777, the Frenchman de Fontanges designed a version of the “flying cape” parachute. A criminal was chosen to test the "cloak". In the presence of law enforcement officers, the inventor and spectators, repeat offender Jacques Doumier climbed the Parisian arms tower and jumped. The flight went well, and the death penalty for the criminal skydiver was abolished.

Soon the Frenchman Louis Sebastian Lenormand modernized the design of Fausto Veranzio. The device looked like an umbrella-shaped canvas dome with slings, glued on the inside with paper to reduce air permeability. In addition, Lenormand invented “parachute” by combining the Greek “para” and the French “chute” into one word, which literally translates as “against the fall.”

André Jacques Garnerin is the first person to jump from a hot air balloon. On October 22, 1797, at an altitude of 1 kilometer above Parc Monceau in Paris, he cut the lines connecting the basket to the eight-meter dome.
Garnerin's wife, Jeanne Genevieve, followed her husband's example, becoming the first woman in the world to complete the jump.

In the 19th century, jumping from heights became popular among traveling parachutists and circus performers. Aerial acrobats made money by performing risky stunts. One of the most famous was Charles Laroux, who created an anti-fall device similar to a large umbrella for a circus trick. The device resembled a strange semi-automatic parachute with 12 wedges, which were connected by slings to a belt belt. The device was fixed to the side of the balloon with a special string with a spring, which opened during the jump, and the parachute was disconnected from the balloon. Laroux died during testing during the flight.

In 1880, Erwin Baldwin invents the automatic parachute. While making a jump, the cord securing the structure with the ball broke under the weight, filling the dome with air.

2 years later, Lev Stevenson creates a traction ring, and Herman Latheman uses a new principle for deploying a parachute from an elongated bag.

Creation of the first aviation parachute

Over time, hot air balloons replaced airplanes. As aviation developed, so did the number of casualties. The parachute as a rescue device for pilots has become a pressing issue.

In 1910, Lev Makarovich Matsievich, a legend of Russian aeronautics, died during demonstration flights in St. Petersburg. Impressed by the tragedy, Gleb Evgenievich Kotelnikov, a theater actor, became eager to construct an aviation parachute. A year later, having completed his work, he created a reliable, compact and lightweight device that was assembled into a backpack, attached to the pilot using a harness. At the bottom of the backpack there were springs that, when the pull ring was pulled out, ejected a silk dome, into the edges of which a thin elastic cable was sewn. The invention, the free-action backpack parachute RK-1, which immediately gained recognition abroad, was registered by Kotelnikov in 1913 in France. The use of the device in Russia began only in the First World War.
Thus, a simple actor played a vital role in the development of world aviation. Over time, backpack parachutes have improved and changed, but the principle of operation remains the same.
