Today (January 25, 1736) is the birthday 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. Coincidentally,
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 major problem in
astronomy, as areas near the edge of the moon 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.
