He spent more than 30 years hiking and sailing. The development of the coast of the Arctic Ocean to the east of the Indigirka and Kolyma rivers is associated with his name. With his satellites, he for the first time circled the eastern tip of Asia and discovered the strait separating Asia from America. But his report and report on the voyage around the Chukotka Peninsula lay in the Yakut archive for more than 80 years and was discovered only during the Great Northern Expedition. 250 years after the voyage, his name was immortalized on the map.

Over the past few centuries, we have made countless discoveries that have helped greatly improve the quality of our daily lives and understand how the world around us works. Assessing the full importance of these discoveries is very difficult, if not almost impossible. But one thing is for sure - some of them literally changed our lives once and for all. From penicillin and the screw pump to x-rays and electricity, here is a list of 25 greatest discoveries and inventions of mankind.
25. Penicillin
If Scottish scientist Alexander Fleming had not discovered penicillin, the first antibiotic, in 1928, we would still be dying from diseases such as stomach ulcers, abscesses, streptococcal infections, scarlet fever, leptospirosis, Lyme disease and many others.
24. Mechanical watch

There are conflicting theories about what the first mechanical watch actually looked like, but most often researchers adhere to the version that they were created in 723 AD by the Chinese monk and mathematician Ai Xing (I-Hsing). It was this seminal invention that allowed us to measure time.
23. Copernican heliocentrism

In 1543, almost on his deathbed, Polish astronomer Nicolaus Copernicus unveiled his landmark theory. According to the works of Copernicus, it became known that the Sun is our planetary system, and all its planets revolve around our star, each in its own orbit. Until 1543, astronomers believed that the Earth was the center of the Universe.
22. Blood circulation

One of the most important discoveries in medicine was the discovery of the circulatory system, which was announced in 1628 by the English physician William Harvey. He became the first person to describe the entire circulatory system and properties of the blood that the heart pumps throughout our body from the brain to the tips of the fingers.
21. Screw pump

One of the most famous ancient Greek scientists, Archimedes, is considered the author of one of the world's first water pumps. His device was a rotating corkscrew that pushed water up a pipe. This invention advanced irrigation systems to new level and is still used in many wastewater treatment plants.
20. Gravity

Everyone knows this story - Isaac Newton, the famous English mathematician and physicist, discovered gravity after an apple fell on his head in 1664. Thanks to this event, we learned for the first time why objects fall down and why planets revolve around the Sun.
19. Pasteurization

Pasteurization was discovered in the 1860s by French scientist Louis Pasteur. It is a heat treatment process during which pathogenic microorganisms are destroyed in certain foods and drinks (wine, milk, beer). This discovery had a significant impact on public health and the development of the food industry around the world.
18. Steam engine

Everyone knows that modern civilization was forged in factories built during the Industrial Revolution, and that it all happened using steam engines. The steam engine was created a long time ago, but over the last century it has been significantly improved by three British inventors: Thomas Savery, Thomas Newcomen and the most famous of them, James Watt.
17. Air conditioning

Primitive climate control systems have existed since ancient times, but they changed significantly when the first modern electric air conditioner was introduced in 1902. It was invented by a young engineer named Willis Carrier, a native of Buffalo, New York.
16. Electricity

The fateful discovery of electricity is attributed to the English scientist Michael Faraday. Among his key discoveries, it is worth noting the principles of electromagnetic induction, diamagnetism and electrolysis. Faraday's experiments also led to the creation of the first generator, which became the forerunner of the huge generators that today produce the electricity we are familiar with in everyday life.
15. DNA

Many believe that it was the American biologist James Watson and the English physicist Francis Crick who discovered it in the 1950s, but in fact this macromolecule was first identified in the late 1860s by the Swiss chemist Friedrich Maischer Miescher). Then, several decades after Maischer's discovery, other scientists conducted a series of studies that finally helped us clarify how an organism passes on its genes to the next generation and how the work of its cells is coordinated.
14. Anesthesia

Simple forms of anesthesia, such as opium, mandrake and alcohol, have been used by people for a long time, and the first mention of them dates back to 70 AD. But pain management moved to a new level in 1847, when American surgeon Henry Bigelow first introduced ether and chloroform into his practice, making extremely painful invasive procedures much more tolerable.
13. Theory of relativity

Comprising Albert Einstein's two related theories, special and general relativity, the theory of relativity, published in 1905, transformed all of 20th century theoretical physics and astronomy and eclipsed Newton's 200-year-old theory of mechanics. Einstein's theory of relativity has become the basis for much of modern scientific work.
12. X-rays

German physicist Wilhelm Conrad Rontgen accidentally discovered X-rays in 1895 when he observed fluorescence produced by a cathode ray tube. For this pivotal discovery, the scientist was awarded the Nobel Prize in 1901, the first of its kind in the physical sciences.
11. Telegraph

Since 1753, many researchers have experimented with establishing long-distance communication using electricity, but a significant breakthrough did not come until several decades later, when Joseph Henry and Edward Davy invented the electrical relay in 1835. Using this device they created the first telegraph 2 years later.
10. Periodic table of chemical elements

In 1869, Russian chemist Dmitri Mendeleev noticed that if chemical elements are ordered by their atomic mass, they tend to fall into groups with similar properties. Based on this information, he created the first periodic table, one of the greatest discoveries in chemistry, which was later called the periodic table in his honor.
9. Infrared rays

Infrared radiation was discovered by British astronomer William Herschel in 1800 when he studied the heating effect of different colors of light, using a prism to separate the light into a spectrum, and measuring the changes with thermometers. Today, infrared radiation is used in many areas of our lives, including meteorology, heating systems, astronomy, tracking heat-intensive objects and many other areas.
8. Nuclear magnetic resonance

Today, nuclear magnetic resonance is continually used as an extremely accurate and effective diagnostic tool in the medical field. This phenomenon was first described and calculated by American physicist Isidor Rabi in 1938 while observing molecular beams. In 1944, the American scientist was awarded the Nobel Prize in Physics for this discovery.
7. Moldboard plow

Invented in the 18th century, the moldboard plow was the first plow that not only dug up the soil, but also stirred it, making it possible to cultivate even very stubborn and rocky soil for agricultural purposes. Without this weapon Agriculture as we know it today, in northern Europe or in central America wouldn't exist.
6. Camera obscura
Photo: wikimedia
The forerunner of modern cameras and video cameras was the camera obscura (translated as dark room), which was an optical device used by artists to create quick sketches while traveling outside their studios. A hole in one of the walls of the device served to create an inverted image of what was happening outside the chamber. The picture was displayed on the screen (on the wall of the dark box opposite the hole). These principles have been known for centuries, but in 1568 the Venetian Daniel Barbaro modified the camera obscura by adding converging lenses.
5. Paper
Photo: pixabay
The first examples of modern paper are often considered to be papyrus and amate, which were used by ancient Mediterranean peoples and pre-Columbian Americans. But it would not be entirely correct to consider them real paper. References to the first production of writing paper date back to China during the reign of the Eastern Han Empire (25-220 AD). The first paper is mentioned in chronicles dedicated to the activities of the judicial dignitary Cai Lun.
4. Teflon

The material that keeps your pan from burning was actually invented completely by accident by American chemist Roy Plunkett when he was looking for a replacement refrigerant to make household life safer. During one of his experiments, the scientist discovered a strange, slippery resin, which later became better known as Teflon.
3. Theory of evolution and natural selection
Photo: wikimedia
Inspired by his observations during his second voyage of exploration in 1831-1836, Charles Darwin began writing his famous theory of evolution and natural selection, which, according to scientists around the world, became a key description of the mechanism of development of all life on Earth
2. Liquid crystals

If the Austrian botanist and physiologist Friedrich Reinitzer had not discovered liquid crystals while testing the physicochemical properties of various cholesterol derivatives in 1888, today you would not know what LCD televisions or flat-panel LCD monitors are.
1. Polio vaccine
Photo: GDC Global / flickr
On March 26, 1953, American medical researcher Jonas Salk announced that he had successfully tested a vaccine against polio, a virus that causes a severe chronic disease. In 1952, an epidemic of the disease diagnosed 58,000 people in the United States and claimed 3,000 innocent lives. This spurred Salk on a quest for salvation, and now the civilized world is safe at least from this disaster.
