Scientific advances in medicine: By the 19th century, anatomy’s development was almost equivalent to the modern level, so the main research interest was aimed at studying the anatomy of tissues. At that time, many discoveries were made to explain certain diseases occurring in tissues. In physiology, the structure of individual structures of the brain, nervous arch, sensory organs, digestive and respiratory systems, the functioning of the heart and other mechanisms was actively studied. The process of nerve impulse transmission and much more has been discovered. The method of experimenting on animals began to be widely used. Charles Darwin's theory of evolution contributed greatly to the success of biology. A cellular theory of the structure of living organisms is proposed. The concept of genetics was born and its basic laws were proposed. Chemistry did not lag behind: in 1869 D.I. Mendeleev discovered the periodic law of chemical elements and created their system (table). Great strides have been made in the study of infectious diseases. Pharmacology developed. The 19th century was the century of major discoveries in the field of surgery.

Louis Pasteur - French microbiologist and chemist, member of the French Academy (1881). Pasteur, having shown the microbiological essence of fermentation and many human diseases, became one of the founders of microbiology and immunology. His work in the field of crystal structure and polarization phenomena formed the basis of stereochemistry. Pasteur also put an end to the centuries-old dispute about the spontaneous generation of some forms of life at the present time, experimentally proving the impossibility of this. His name is widely known in non-scientific circles thanks to the pasteurization technology he created and later named after him. Louis Pasteur (1822 – 1895)

Sigmund Freud (full name Sigismund Shlomo Freud) is an Austrian psychologist, psychiatrist and neurologist. Sigmund Freud is best known as the founder of psychoanalysis, which had a significant influence on psychology, medicine, sociology, anthropology, literature and art of the 20th century. Freud's views on human nature were innovative for his time and throughout the researcher's life they continued to resonate in the scientific community. Interest in the scientist’s theories continues to this day. Despite the fact that the influence of Freud's ideas and personality on psychology is undeniable, many researchers consider his works to be intellectual quackery. Sigmund Freud (1856 – 1939)

Charles Robert Darwin, an English naturalist and traveler, was one of the first to realize and clearly demonstrate that all types of living organisms evolve over time from common ancestors. In his theory, the first detailed presentation of which was published in 1859 in the book “On the Origin of Species,” Darwin called natural selection and uncertain variability the main driving force of evolution. The role of the force that shaped Darwin's understanding of changing natural conditions as the driving force of natural selection was played by artificial selection, which had by that time achieved significant development in English agriculture and made it common to view domesticated animals and domesticated plants as the result of such selection. Charles Robert Darwin (1809 – 1882)

Slide description:
The existence of evolution was recognized by most scientists during Darwin's lifetime, while his theory of natural selection as the main explanation of evolution became generally accepted only in the 30s of the 20th century with the advent of the synthetic theory of evolution. Darwin's ideas and discoveries, as revised, form the foundation of the modern synthetic theory of evolution and form the basis of biology as providing a logical explanation for biodiversity. Orthodox followers of Darwin's teachings develop the direction of evolutionary thought that bears his name (Darwinism). Signature of Charles Darwin

George Stephenson (9 June 1781, Wylam - 12 August 1848, Chesterfield, Derbyshire) - English inventor and mechanical engineer. He gained worldwide fame thanks to the steam locomotive he invented. Considered one of the “fathers” of railways. The track gauge he chose, 1435 mm (4 feet 8½ inches, the so-called “Stephenson” or “normal gauge”), became the most common in Western Europe and is still the standard on the railways of many countries around the world.

Robert Fulton At school, young Robert did not shine with success, preferring to spend his free time in local gunsmiths, drawing, sketching and making fireworks. At the age of 12, Robert became interested in steam engines, and already at the age of 14 he successfully tested his boat, equipped with a hand-powered wheel propulsion unit.
Question 01. Explain the reasons for the rapid development of physics and other natural sciences in the 19th century.
Answer. Discoveries in the field of natural sciences immediately found practical implementation in new inventions, which immediately brought fame (as well as money), which stimulated scientists to make new discoveries and young people to engage in science. Research began to require investment, but thanks to the discoveries, both business and government were interested in sponsoring the natural sciences.
Question 02. Fill out the table “The most important scientific discoveries in the 19th - early 20th centuries” in your notebook. Columns of the table: scientific field, year of discovery, name of the scientist, content and significance of the discovery.
Question 03. Prepare a message about a discovery. Also use the text of the document. What qualities do you think a scientist should have?
Answer. Charles Darwin went to his discovery for many years. He traveled on a ship of the English navy, on which he traveled around the world and made many observations as a naturalist, because the voyage lasted five years. For example, in the Galapagos Islands (in the Pacific Ocean) he studied finches. He noticed that with approximately the same body shape, many species of finches have different beak shapes and sizes. He suggested that they descended from the same ancestor, but over time, development separated them into different species. When he returned, he began to study the selection of domestic animals, on the basis of which new breeds appeared. He was especially interested in pigeons. People obtained a wide variety of colors for these birds by selecting from the offspring only individuals with the qualities they desired. Darwin suggested that nature does the same thing: it selects the qualities it needs and allows organisms with only these qualities to leave offspring. He consolidated his conclusions using the example of plants. Thus Darwin's theory of evolution was born, which he published in 1859. But that wasn't the end of the story. Further, Darwin had to endure fierce polemics with opponents of his theory until the end of his life.
Charles Darwin knew how to collect material, draw conclusions from it that others had not thought of, and knew how to confirm these conclusions. He had the industriousness to develop his theory, the determination to publish it, the tenacity to defend it, and the longevity to display the above qualities. This is exactly what, in my opinion, pioneers need (although, I believe, there is no universal set of qualities characteristic of all of them).
Question 04. Describe the successes of medicine at the turn of the 19th-20th centuries. Think about the reasons for these successes.
Answer. Medicine in the 19th century developed vaccines for many diseases and clarified the connection between public hygiene and epidemics. All this made it possible to deal much better with many mass diseases and laid the foundations for a complete or almost complete victory over them in the twentieth century. Anesthesia was discovered in surgery, and an X-ray machine appeared. Thanks to these and many other discoveries, wounds previously considered fatal were now treatable. In many ways, the reasons for these successes lie in interaction with other natural sciences. The emergence of microbiology and a vaccine against rabies would not have been possible without the development of microscopes (respectively, optics), the X-ray machine was named after the physicist because it would not have been possible without his discovery, the work of chemists made it possible to create new medicines, etc.

(sl. 6)
Reasons for the development of science in modern times:
1. Life itself demanded to know the laws and use them in production
2. Radical changes in the consciousness and thinking of people of the New Age.
(sl. 7) In 1831, Michael Faraday discovered the phenomenon of electromagnetic induction, which made it possible to begin creating an electric motor. He became a Fellow of the Royal Society.
Let's find out more about him.
Michael was born on September 22, 1791 in Newton Butts (now Greater London). His father was a poor blacksmith from the London suburbs. His elder brother Robert was also a blacksmith, who in every possible way encouraged Michael’s thirst for knowledge and at first supported him financially. Faraday's mother, a hardworking and uneducated woman, lived to see her son achieve success and recognition, and was rightfully proud of him. The family's modest income did not allow Michael to even graduate from high school; at the age of thirteen he began working as a supplier of books and newspapers, and then at the age of 14 he went to work in a bookstore, where he studied bookbinding. Seven years of work in a workshop on Blandford Street became for the young man years of intense self-education. All this time, Faraday worked hard - he enthusiastically read all the scientific works he bound on physics and chemistry, as well as articles from the Encyclopedia Britannica, and repeated the experiments described in books on homemade electrostatic devices in his home laboratory. An important stage in Faraday’s life was his studies at the City Philosophical Society, where Michael listened to popular science lectures on physics and astronomy in the evenings and participated in debates. He received money (a shilling to pay for each lecture) from his brother. At the lectures, Faraday made new acquaintances, to whom he wrote many letters in order to develop a clear and concise style of presentation; he also tried to master the techniques of oratory.
Gradually, his experimental research increasingly shifted to the field of physics. After the discovery in 1820 by H. Oersted of the magnetic effect of electric current, Faraday was fascinated by the problem of the connection between electricity and magnetism. In 1822, an entry appeared in his laboratory diary: “Convert magnetism into electricity.” Faraday's reasoning was as follows: if in Oersted's experiment the electric current has a magnetic force, and, according to Faraday, all forces are interconvertible, then magnets should excite the electric current. In the same year, he attempted to find the polarizing effect of current on light. By passing polarized light through water located between the poles of a magnet, he tried to detect the depolarization of light, but the experiment gave a negative result.
In 1823, Faraday became a member of the Royal Society of London and was appointed director of the physical and chemical laboratories of the Royal Institution, where he conducted his experiments.
(sl. 8) In the 1860s, he developed the electromagnetic theory of light, which summarized the results of experiments and theoretical constructions of many physicists in different countries in the field of electromagnetism.
James Clerk Maxwell) - British physicist and mathematician. Scottish by birth. Member of the Royal Society of London (1861). Maxwell laid the foundations of modern classical electrodynamics (Maxwell's equations), introduced the concepts of displacement current and electromagnetic field into physics, and obtained a number of consequences from his theory (prediction of electromagnetic waves, electromagnetic nature of light, light pressure, and others). One of the founders of the kinetic theory of gases (established the distribution of gas molecules by speed). He was one of the first to introduce statistical concepts into physics, showed the statistical nature of the second law of thermodynamics (“Maxwell’s demon”), and obtained a number of important results in molecular physics and thermodynamics (Maxwell’s thermodynamic relations, Maxwell’s rule for the liquid-gas phase transition, and others). Pioneer of quantitative color theory; author of the principle of color photography. Among Maxwell's other works are studies on the stability of Saturn's rings, the theory of elasticity and mechanics (photoelasticity, Maxwell's theorem), optics, and mathematics. He prepared manuscripts of Henry Cavendish's works for publication, paid a lot of attention to the popularization of science, and designed a number of scientific instruments.
(sl. 9) According to his theory, there are invisible waves in nature that transmit electricity in space. Light is a type of electromagnetic vibration.
(page 10) In 1883, the German engineer Heinrich Hertz confirmed the existence of electromagnetic waves and proved that no material object could prevent their propagation
Heinrich Rudolf Hertz- German physicist.
Graduated from the University of Berlin, from 1885 to 1889. was a professor of physics at the University of Karlsruhe. Since 1889 - professor of physics at the University of Bonn.
The main achievement is the experimental confirmation of James Maxwell's electromagnetic theory of light. Hertz proved the existence of electromagnetic waves. He studied in detail the reflection, interference, diffraction and polarization of electromagnetic waves, proved that the speed of their propagation coincides with the speed of propagation of light, and that light is nothing more than a type of electromagnetic waves. He constructed the electrodynamics of moving bodies based on the hypothesis that the ether is carried away by moving bodies. However, his theory of electrodynamics was not confirmed by experiments and later gave way to the electronic theory of Hendrik Lorentz. The results obtained by Hertz formed the basis for the development of radio.
In 1886-87 Hertz was the first to observe and describe the external photoelectric effect. Hertz developed the theory of a resonant circuit, studied the properties of cathode rays, and investigated the effect of ultraviolet rays on electric discharge. In a number of works on mechanics, he gave the theory of impact of elastic balls, calculated the time of impact, etc. In the book “Principles of Mechanics” (1894), he deduced the general theorems of mechanics and its mathematical apparatus, based on a single principle (Hertz’s principle).
Since 1933, the frequency unit Hertz, which is included in the international metric system of units SI, has been named after Hertz.
(sl. 11) Hertz established that electromagnetic waves propagate at a speed of 300 thousand km/s. These waves became known as Hertz waves. It was on the basis of these discoveries that Marconi and Popov created the wireless telegraph. In 1897 A.S. Popov sent the first telegram, consisting of two words: “Heinrich Hertz”
- (sl. 12) Nevertheless, discoveries continued. Back in 1878, the Dutch physicist Hendrik Anton Lorenz tried to explain Maxwell's electromagnetic theory from the point of view of the atomic structure of matter
Hendrik Anton Lorenz
Lorenz studied physics and mathematics at Leiden University. His astronomy teacher, Professor Frederick Kaiser, had a great influence on him as a future physicist. At the University of Leiden from 1878 he then worked as a professor of mathematical physics. In 1880, together with his almost namesake Ludwig Lorentz, he derived the Lorentz-Lorentz formula. He developed the electromagnetic theory of light and the electronic theory of matter, and also formulated a self-consistent theory of electricity, magnetism and light. The name of this scientist is associated with the Lorentz force, known from school physics courses (the concept of which he developed in 1895), a force acting on an electric charge moving in a magnetic field. In electrodynamics, the method of calculating the local field, first proposed by Lorentz, and known as the “Lorentz sphere”, is widely used.
He developed a theory about transformations of the state of a moving body, describing the decrease in the length of an object during translational motion. The Lorentz transformations obtained within the framework of this theory are a major contribution to the development of the theory of relativity.
For his explanation of the phenomenon known as the Zeeman effect, he was awarded the Nobel Prize in Physics in 1902 together with another Dutch physicist Pieter Zeeman
(sl. 13) That., A revolution took place in the natural scientific ideas of mankind, a new picture of the world was formed, which still exists today
(page 14) At the end of 1895 in Germany, physicist Wilhelm Conrad Roentgen, based on Maxwell’s theory of electromagnetic waves, discovered invisible rays, which he called X-rays.
Discovery of the rays
Despite the fact that Wilhelm Roentgen was a hardworking man and, as the head of the physics institute at the University of Würzburg, he used to stay late in the laboratory, he made the main discovery in his life - X-rays - when he was already 50 years old. November 8, 1895, Roentgen's experiments showed the basic properties of previously unknown radiation, which was called X-rays. As it turns out, X-rays can penetrate many opaque materials; however, it is not reflected or refracted. X-ray radiation ionizes the surrounding air and illuminates the photo plates. ((page 15) Also, Roentgen made the first photographs using X-rays.
The discovery of the German scientist greatly influenced the development of science. Experiments and studies using X-rays helped to obtain new information about the structure of matter, which, together with other discoveries of that time, forced us to reconsider a number of principles of classical physics. After a short period of time, X-ray tubes found application in medicine and various fields of technology.
Representatives of industrial companies approached Roentgen more than once with offers to profitably purchase the rights to use the invention. But Wilhelm refused to patent the discovery, since he did not consider his research a source of income.
By 1919, X-ray tubes had become widespread and were used in many countries. Thanks to them, new areas of science and technology emerged - radiology, x-ray diagnostics, x-ray measurements, x-ray diffraction analysis, etc.
(sl. 16)- A whole group of scientists - Henri Becquerel, Pierre Maria Sklodowska - Curie, Ernest Rutherford, Niels Bohr - studied radioactivity and created the doctrine of the complex structure of the atom.
(sl. 17) In 1903, Marie and Pierre Curie, together with Henri Becquerel, received the Nobel Prize in Physics “for outstanding services in joint research into the phenomena of radiation.”
(sl. 18) A revolution in natural science was made by the book of the great scientist and naturalist Charles Darwin “On the Origin of Species”
Charles Robert Darwin- English naturalist and traveler, was one of the first to realize and clearly demonstrate that all types of living organisms evolve over time from common ancestors. In his theory, the first detailed presentation of which was published in 1859 in the book “On the Origin of Species,” Darwin called natural selection and uncertain variability the main driving force of evolution. The existence of evolution was recognized by most scientists during Darwin's lifetime, while his theory of natural selection as the main explanation of evolution became generally accepted only in the 30s of the 20th century with the advent of the synthetic theory of evolution. Darwin's ideas and discoveries, as revised, form the foundation of the modern synthetic theory of evolution and form the basis of biology as providing a logical explanation for biodiversity. Orthodox followers of Darwin's teachings develop the direction of evolutionary thought that bears his name (Darwinism).
(pp. 42 – 43 – textbook statement by Darwin)
(sl. 19) In 1885, the scientist saved the life of a young man who was bitten 14 times by a rabid dog. He was working on obtaining a rabies serum. Gave the world a new science - microbiology
Louis Pasteur- French microbiologist and chemist, member of the French Academy (1881). Pasteur, having shown the microbiological essence of fermentation and many human diseases, became one of the founders of microbiology and immunology. His work in the field of crystal structure and polarization phenomena formed the basis of stereochemistry. Pasteur also put an end to the centuries-old dispute about the spontaneous generation of some forms of life at the present time, experimentally proving the impossibility of this (see The Origin of Life on Earth). His name is widely known in non-scientific circles thanks to the technology he created and later named after him pasteurization.
Pasteur began studying fermentation in 1857. By 1861, Pasteur showed that the formation of alcohol, glycerol and succinic acid during fermentation can only occur in the presence of microorganisms, often specific ones.
Louis Pasteur proved that fermentation is a process closely related to the vital activity of yeast fungi, which feed and multiply at the expense of fermenting liquid. In clarifying this issue, Pasteur had to refute Liebig's view of fermentation as a chemical process, which was dominant at that time. Particularly convincing were Pasteur's experiments with a liquid containing pure sugar, various mineral salts that served as food for the fermenting fungus, and ammonium salt, which supplied the fungus with the necessary nitrogen. The fungus developed, increasing in weight; ammonium salt was wasted. Pasteur showed that lactic fermentation also requires the presence of a special “organized enzyme” (as living microbial cells were called at that time), which multiplies in the fermenting liquid, also increasing in weight, and with the help of which fermentation can be caused in new portions of the liquid.
At the same time, Louis Pasteur made another important discovery. He found that there are organisms that can live without oxygen. For some of them, oxygen is not only unnecessary, but also poisonous. Such organisms are called strict anaerobes. Their representatives are microbes that cause butyric acid fermentation. At the same time, organisms capable of both fermentation and respiration grew more actively in the presence of oxygen, but consumed less organic matter from the environment. Thus, it has been shown that anaerobic life is less efficient. It has now been shown that from the same amount of organic substrate, aerobic organisms are able to extract almost 20 times more energy than anaerobic organisms.
(page 20)
Study of infectious diseases
In 1864, French winemakers turned to Pasteur with a request to help them develop means and methods of combating wine diseases. The result of his research was a monograph in which Pasteur showed that wine diseases are caused by various microorganisms, and each disease has a specific pathogen. To destroy harmful “organized enzymes,” he suggested heating the wine at a temperature of 50-60 degrees. This method, called pasteurization, is widely used in laboratories and in the food industry.
In 1865, Pasteur was invited by his former teacher to the south of France to find the cause of silkworm disease. After the publication of Robert Koch’s work “The Etiology of Anthrax” in 1876, Pasteur devoted himself entirely to immunology, finally establishing the specificity of the causative agents of anthrax, puerperal fever, cholera, rabies, chicken cholera and other diseases, developed ideas about artificial immunity, and proposed a method of preventive vaccinations , in particular against anthrax (1881), rabies (together with Emile Roux 1885), involving specialists from other medical specialties (for example, surgeon O. Lannelong).
The first vaccination against rabies was given on July 6, 1885 to 9-year-old Joseph Meister at the request of his mother. The treatment was successful, and the boy did not develop symptoms of rabies.
Interesting Facts
Pasteur spent his entire life studying biology and treating people, without receiving either a medical or biological education.
Pasteur also painted as a child. When J.-L. Jerome saw his work years later, he said how good it was that Louis chose science, since he would have been a great competitor to us.
In 1868 (at the age of 46), Pasteur suffered a cerebral hemorrhage. He remained disabled: his left arm was inactive, his left leg dragged along the ground. He almost died, but eventually recovered. Moreover, after this he made the most significant discoveries: he created a vaccine against anthrax and vaccinations against rabies. When the scientist died, it turned out that a huge part of his brain was destroyed. Pasteur died of uremia.
According to I. I. Mechnikov, Pasteur was a passionate patriot and a hater of the Germans. When they brought him a German book or pamphlet from the post office, he took it with two fingers and threw it away with a feeling of great disgust.
Later, a genus of bacteria, pasteurs, causing septic diseases, to the discovery of which he apparently had nothing to do, was named after him.
Pasteur was awarded orders from almost all countries of the world. In total he had about 200 awards.
(sl. 21) At the end of the 18th century, an English doctor noticed that milkmaids did not get smallpox, which at that time was killing thousands of people. Jenner quite correctly explained this by saying that milkmaids in a weak form become infected with smallpox from cows and this creates immunity in them. Therefore, he developed the first vaccine - against smallpox. Jenner came up with the idea of injecting the seemingly harmless cowpox virus into the human body.
(f. 22) At the beginning of the 19th century, Jean Corvisart “listened” to his patients using a special stick and determined the condition of the lungs and heart by sound. Rene Laenne, a student of Jean Corvisart, discovered that solids produce sounds in different ways. He constructed a tube made of beech wood - a stethoscope. One end was applied to the patient's chest, and the other to the doctor's ear.
(sl. 23) German microbiologist, discovered the anthrax bacillus, Vibrio cholerae and tuberculosis bacillus. For his research on tuberculosis he was awarded the Nobel Prize in Physiology or Medicine in 1905.
Koch later made attempts to find the causative agent of tuberculosis, a widespread disease at that time and a leading cause of death. The proximity of the Charite clinic, filled with tuberculosis patients, makes his task easier - every day, early in the morning, he comes to the hospital, where he receives material for research: a small amount of sputum or a few drops of blood from patients with consumption.
However, despite the abundance of material, he still fails to detect the causative agent of the disease. Koch soon realizes that the only way to achieve his goal is with the help of dyes. Unfortunately, ordinary dyes turn out to be too weak, but after several months of unsuccessful work, he still manages to find the necessary substances.
Institute of Microbiology on Dorotheestrasse in Berlin - here Robert Koch discovered the causative agent of tuberculosis
Koch stains the crushed tuberculosis tissue of the 271st drug in methyl blue, and then in the caustic red-brown dye used in finishing leather, and discovers tiny, slightly curved, bright blue colored rods - Koch's rods.
On March 24, 1882, when he announced that he had isolated the bacterium that causes tuberculosis, Koch achieved the greatest triumph of his entire life. At that time, this disease was one of the main causes of death. In his publications, Koch developed the principles of “obtaining evidence that a particular microorganism causes certain diseases.” These principles still form the basis of medical microbiology.
Koch's study of tuberculosis was interrupted when, on instructions from the German government, he went to Egypt and India as part of a scientific expedition to try to determine the cause of cholera.
