Today (April 10, 1813) is the Memorial Day of Joseph Louis Lagrange, a French scientist who achieved the feat of mathematics at the age of twenty.
Joseph Louis Lagrange was born on January 25, 1736, in Turin to Italian parents. The wealthy mother was born as the 11th child to her father and was the only one beyond childhood, but the wealth of the expensive father did not surpass her. When I was in college at the age of 17, Lagrange's passion was culture and literature. In one of Haley's essays, he read that Newton's calculus was far better than the Greeks' geometric methods. Within a year or two of that impulse, he learned all that he knew in geography and sowed the seeds for his later analysis, which would be published in 1788. The book's charitable transformation into statics is similar to Newton's revolution in gravity.
While in Turin, the first journal of the University of Turin was published. Lagrange was then 23. Not only did he assume the responsibility of editing and publishing all the articles in the magazine, but he also published his own work, Maxima & Minima. In those research notes, he outlined how the 'Variational Calculus' he was going to make would later change statics. He still used Newton's differential calculus for probability theory. This was not enough to make a special twist on the mathematical theory of sound. By analyzing how linear particles react with particle-jumping vibrations, he transformed the phonetics that had been researched until then as part of fluid dynamics, allowing phonology to dominate the aggregate kinetics of flexible particles.
He succeeded in trying to put an end to a debate that had been going on widely for many years among mathematicians. The problem is with a spinning wire or wire. The problem is what is its proper mathematical formulation. It is not surprising that Lagrange, who achieved all this by the age of 23, was considered by the scientific world to be the equivalent of the eminent mathematicians of the time, such as Euler and Bernoulli.
His skyscraper, The Mecanique Analytique, appeared in his mind at the age of 19 and was published at the age of 58, and is still considered an essential textbook for Analytical Dynamics . First-class contributor in the fields of algebraic equations, astronomy, number theory, algebra probability of variations, etc.
Wandering was a significant problem in astronomy, as areas near the moon's edge disappeared. Why does Monday always show almost the same face when viewed from this planet? Is this to be deduced from Newton's laws of gravitation? The root of the problem is the 'problem of the three spheres' which has been explored ever since. In 1764, Lagrange was awarded the Grand Prize of the French Academy of Sciences for solving Monday's wandering problem. Following this, the academy released another issue and rewarded it with a lawsuit. In 1772, 1774 and 1778 he won three more prizes of the same type.
At the age of thirty, Lagrange was invited to Berlin and appointed director of the physics-mathematics department of the academy. The caller was Frederick, who at the time proclaimed himself 'the greatest king in Europe'. For twenty years research papers from Lagrange have been coming in one after another. At the academy, he had no restriction on teaching or speaking any other subject. King Frederick was delighted not only by Lagrange's genius but also by his loving and supportive nature. Joseph Louis Lagrange, a mathematician under the age of twenty, passed away on April 10, 1813, at the age of 77 in Paris, France.
