Leonard Euler a Swiss mathematician and physicist. He has made significant contributions to calculus, numerology, insulating equations, graph theory and topography. Many contributions and concepts used in modern mathematics are his contribution.The concept of mathematical functions used in mathematical analysis is his invention. Euler e, π for pie, introduced Σ to add. He also contributed in mechanics, optics and astronomy. During his contemporaries, he did not have a mathematician complete with such publications. Even after improving the printing system, the number of scientists completing the same publication is very low.Euler was considered one of the best mathematicians of the 18th century and one of the best mathematicians of all time. His published research work among mathematicians is still the highest and it is a Guinness record. Laplace was said about him: "Lisez Euler, lisez Euler, c'est notre maître à tous" ("Euler recite, read Euler, he is our teacher.")
2002 Euler named Asteroid in his honor Is named. Swiss 10-Fra's notes and numerous photographs in Switzerland, Russia and Germany have pictures of them.

First life :
Euler's father was Paul Euler. He was a priest of Reformed Church. Mother was Margaret Brocker, she was also a priest's daughter. Euler had two younger sisters, Anna Maria and Maria Magdalena. Euler's age was one year when Euler's family left Basel and settled in Rhein, where Euler was an early childhood. Paul Euler was a family friend of the Bernoulli family-Johann Bernoulli, who was considered to be the best mathematician of Europe at that time. Bernoulli had a profound influence on young Euler. Euler was sent to his grandfather at Basel for elementary education. He was admitted to Basel University at the age of 13, and in 1723, he achieved master's degree in philosophy by analyzing the philosophical ideas of Descartes and Newton. During this time, he used to go to Johann Bernoulli every Saturday afternoon, who can understand the extraordinary mathematical talent of his student. In order to become a priest of his father's wishes, he started studying theology, Greek, and Hebrew, but Bernoulli Paul Euler, The son was born to take the position of the best mathematician. Euler completed his education at the University of Euler in 1726 and completed Ph.D. on the sound of the title of D Sono. In 1727, he wrote an essay on 'How to make the best of the ship's fleet', in Paris Academy of Prize Problems For the grand prize given That year he received the first award, Pierre Buguyar, father of Naval Architecture. Euler gained second place. Later, Euler received the award 12 times in his life.
In 1957, Euler's 250th birth anniversary commemorative stamp was published by the former Soviet Union. It was written on: 250th birth anniversary of great mathematician and scholar Leonard Euler :
Contribution to Physics and Mathematics :
Euler has worked in almost all branches of mathematics: geometry, infinitival calculus, trigonometry, algebra, and number theory, as well as Continuum physics, moon theory, and other areas of physics. He is a prolific personality in the history of mathematics; When printed, his writings, most of which are basically work, will occupy approximately 60 to 80 quarto volumes. Euler's name is associated with a lot of topics.
Mathematical symbol :
Euler popularized and popularized many new symbols in a large volume and well-publicized textbook. The most notable of these is that he introduced the first function and published f (x) as a function of f by x. He also introduced the modern practice of trigonometric functions, by introduction of the natural logarithm (which is also known as Euler's number) by e, sum of Greek letters Σ and the introduction of imaginary numbers by I. The circumference and diameter of the circle by Greek letter 'π He also popularized the style of publication, but this symbol is not invented.
Numerology :
Euler's interest in numbers was due to Christian Goldbach, his associate's father's Suhrid Academy Academy Number of Euler's primary work in numbers was based on the number of papers in the numerology, Piey de Ferma. Euler extends some of Ferma's works and proves some guesses wrong. Euler establishes an analysis of the distribution of basic numbers. He proved that the sum of the reverse of the prime number is disastrous. While proving this, he found the relation between the Riemann zeta function and the prime number; Which is known as Euler Generator Sources of the Riemann Zeta Function. Euler Newton's Asheid, Fermat's small theorem proved to be a two-class compound theorem and played a significant role in the four class theory of Lagrange. He invented the Tissent Function φ (n), which is the number of integers n equal to or less than the integer n and the number corresponding to n. Using the specialty of this function, he generalized the Fermat's short theorem, which is now well-known as Euler's theorem. He added a new dimension to the study of perfect numbers, from the time of Euclid, the mathematician's special attraction was that of mathematics. Furthermore, Euler played a role in the development of the basic number theory, and guessed the rule of class reversal. These two ideas are considered the basis theory of numerology, and this idea later broadens the way Gauss works.
Geometric Samples of Euler's Formula :
Graph theory :
In 1736, Euler resolved the problem of seven bridges in Königsberg. The city of Königsberg in Prussia was on the banks of the Praxel River and the two large islands were connected through seven bridges. The problem was that it was possible that each of the seven bridges could be returned to starting position using just one time. It's not possible: because it does not make Euler's circuit. The solution is considered to be the first theorem of graph theory, especially in the theory of plane graphs. Euler discovered V-E + F = 2, which is also true for flat graphs, which combines the top, edge, and floor of any convex multiplier. The constant of the equation is known as Euler's specialty of its graph, which is related to the mass of the object.The generalization of the equation in Kos and La Illiér , which introduced a new branch of mathematics called Topolzi.
Physics and Astronomy :
Euler developed an Euler-Bernoulli beam equation jointly with Bernoulli, which is considered as a foundation of engineering. Euler also recognized his talent in classical mechanics and astronomy. As a recognition of his work in astronomy, he was awarded several Paris Academy Awards throughout his career. Among his achievements are the calculation of comets and other space objects orbits, calculation of comet behavior, and the parallel calculation of the sun. He also contributed to the calculation of lingitudine tables. Apart from that, Euler contributed significantly to optics. He disagreed with Newton's particle theory in his optics, which was a theory established at that time. His article presented in 1740 helped to establish the theory of Christian Hyegen's wave of light, which was dominant until the introduction of Quantum theory of light.
Personal philosophy and religious beliefs :
Euler and his friend Daniel Bernoulli were the sole agents of Libyans and against the philosophy of Christian Wolf. Euler firmly believed that knowledge was based on accurate quantitative rules, that doctrines were absent in single entity theory and ULF science. Euler's religious beliefs also played a role in disliking his doctrine; He even identified Wolf's doctrine as "pagan and atheism." Many of Euler's beliefs have been written by his letter to the German princess and his earlier work, Rettung der Göttlichen Offenbahrung Gegen die Einwürfe der Freygeister (the defense of divine inspiration in response to the charge of free theorists). Goes. From these works, it is understood that Euler was a devoted Christian. There is a famous humorous story about Euler's debate about religion with secular philosophers, which took place during the second phase of Euler's time in Pitrebourg bus. French philosopher Dennis Didero was traveling to Russia on the invitation of Catherine the Great. So empress was concerned that philosophical atheism might have influenced members of his court, and so Euler was ordered to deal with the French philosopher. Dindroo was informed that the existence of a learned mathematician has proved to be: He agreed to see the evidence presented in the court. Euler appeared there, near Dindere and proclaimed full confidence in the neck, "Mr., {\ displaystyle {\ frac {a + b ^ {n}} {z}} = x}, so God is there-answer!" Didero, to which the Hebrew language was mathematical (according to the story), stood upset and burst into the laughter of the whole court. Ashamed, he asked permission from the empress to leave Russia, so that Samrajni agreed with Khushmani. However, the story is as ridiculous as it seems, because it was a reputed mathematician whose mathematical research paper published.
The best speech of Leonard Euler :
"I wanted to make a water fountain in my garden: Euler calculates the amount of energy needed to collect water from the reservoir, which flows through the channel and eventually emits from Sansawowi. The call was geomatically constructed, but it could not even take one granular water into fifty yards of the reservoir. Only the boast of lies! Glamor with geometry! "
Thanks for reading............
Great write-up. If children were to have lot of father, then he should be considered one of the fathers of mathematics.
