Mathematician Chebyshev Biography

For reading 8 minutes 33 views published this article offers a unique opportunity to learn about the life and achievements of an outstanding scientist, whose works have a significant impact on the development of scientific knowledge and methods in the field of mathematics and mechanics. The biography of Chebyshev Paphnutius Chebyshev was born on May 4, he grew and was brought up in the family of a wealthy landowner Lev Pavlovich and his wife Agrafena Ivanovna.

Childhood and youth received primary education Paphnutius at home. His mother was taught to literacy, and the cousin of Avdotya’s cousin and mathematics. In childhood, Chebyshev was engaged in music, and also showed great interest in different mechanisms. The boy often constructed different mechanical toys and devices. When Paphnutia was 11 years old, he and his family moved to Moscow, where he continued to receive education.

Parents hired teachers in physics, mathematics and Latin for their son. In the city of Chebyshev, he entered Moscow University at the Physics and Mathematics Department, having studied in it until 5 years, he defended the master's thesis on the topic "Experience of elementary analysis of the theory of probability." A few months later, Paphnutia of Chebyshev was approved as an adjunct professor of St.

Petersburg University. He taught the highest algebra, geometry, practical mechanics and other disciplines. Expert opinion: Paphnutius Chebyshev, an outstanding Russian mathematician of the 19th century, had a significant impact on the development of probability theory, mathematical statistics and numbers theory. His works on probability theory and mathematical statistics are considered classic and remain relevant until today.

Experts note that Chebyshev made a significant contribution to the development of mathematics and his work remain important for modern research in this area. Simple stories. Paphnutius Chebishev Scientific activity when Chebyshev was 29 years old, he became a professor at St. Petersburg University. A couple of years later he was sent to the UK, France, and then to Belgium. During this time, the biography of Paphnutius received a lot of useful information.

He studied foreign engineering, and also got acquainted with the device of industrial enterprises that make different products. Upon arrival in Russia, Paphnutius continued to engage in scientific activities, developing his own ideas. For his work on the theory of articulated parallelograms and the theory of approaching functions, he was chosen by an ordinary academician. The greatest interest in Chebyshev was in the theory of numbers, applied mathematics, probability theory, geometry, theory of approaching functions and mathematical analysis.

She was dedicated to the theory of numbers. He managed to establish a much better approach - integral logarithm. The work of Chebyshev brought him European popularity. A year later, he published an article “On Easific numbers”, in which he analyzed the convergence of rows depending on prime numbers, and calculated the criterion of their convergence. Paphnutius Chebyshev was the first Russian mathematician of the world level and in probability theory.

In the work “On Middle Assumes”, he first proved the point of view known today on the concept of random quantities, as one of the basic concepts of probability theory. Paphnutius Chebyshev achieved great success in studying the theory of approaching functions. He devoted about 40 years of his life to this topic. The mathematician set and solved the task of finding polynomials, the least evading zero.

Later, Chebyshev’s calculations will be used in computing linear algebra. See also: Aurelius Augustine at the same time a man studied mathematical analysis and geometry. He is the author of the theorem on the integrations of differential binom. Later, Paphnutius Chebyshev published an article on differential geometry, under the original name "On the Crowd of Clothing." In it, he presented a new class of coordinate nets - “Chebyshev networks”.

For many years, Chebyshev worked in the military artillery department, achieving a more further and accurate shooting from the guns. The formula of Chebyshev has survived to this day to determine the range of the projectile, based on its rush angle, starting speed and air resistance. Paphnutius paid great attention to the theory of mechanisms, which devoted about 15 articles.

The fact is interesting that under the influence of discussions with Chebyshev, British scientists James Sylvester and Arthur Kalie became interested in the issues of the cinematics of mechanisms. In years, the mathematician began to deeply study the hinge-red mechanisms. After long calculations and experiments, he created the theory of functions that least evading zero. Chebyshev described his discoveries in detail in the book “Theory of mechanisms known as parallelograms”, becoming the ancestor of the mathematical theory of the synthesis of mechanisms.

Interesting facts of Paphnutius Chebyshev were not only an outstanding mathematician, but also a talented inventor. He has developed many new mechanisms and machines, some of which are still used in industry.For example, Chebyshev was invented by a centrifugal regulator, which is used in steam machines, and the parallelogram mechanism, which is used in sewing machines. Paphnutius Chebyshev was a supporter of higher female education and made a significant contribution to his development in Russia.

He advocated the opening of female gymnasiums and universities, as well as for providing women with the right to enter these educational institutions on a par with men. Thanks to the efforts of Chebyshev and other progressive figures of science and culture, several female gymnasiums and universities were discovered in Russia in the late XIX - early XX centuries, which allowed women to receive higher education and make a significant contribution to the development of science and society.

Paphnutius Chebyshev was the first Russian mathematician awarded the Golden Medal of the Royal Astronomical Society in London. He was elected an honorary member of many foreign academies of sciences, including the French Academy of Sciences and the London Royal Society. Obtaining a gold medal of the Royal Astronomical Society and the election of Chebyshev by an honorary member of the foreign academies of sciences indicate an international recognition of his outstanding merits in the field of mathematics and his significant contribution to the development of world science.

Paphnutius Chebyshev The construction of mechanisms over the years of the scientific biography of Paphnutius Chebyshev constructed more than 40 different mechanisms and approximately 80 of their transformations. Many of them today are used in auto and instrumentation. The scientist developed 2 approximate-controling mechanisms-lambda-shaped and cross. See also: Frank Sinatra in the city also created a “stacking machine” that imitated animal walking.

Paphnutius Chebyshev gathered an original wheelchair, which was a self -rolling chair. In addition, the mechanic is the creator of an automatic arithmometer, which today can be seen at the Paris Museum of Arts and Crafts. This is not all the inventions of Paphnutia, which were distinguished by productivity and an innovative approach to business.
