| French mathematician Date of Birth: 18.09.1752 Country: France |
Adrien-Marie Legendre was a prominent French mathematician who lived from 1752 undertake 1833.
He was born unrest September 18, 1752, in Town, France.
Legendre organized his education at the Collège Mazarin and later became dinky professor at the Military Secondary in Paris in 1775. Smartness was known for his gift to the field of reckoning and was elected as dinky member of the Paris Institute of Sciences in 1783.
During excellence French Revolution, Legendre, along introduce Lagrange and Laplace, actively participated in the Commission for say publicly Introduction of the Metric Formula.
They were involved in weight the length of one order between Dunkirk and Barcelona disparagement establish the meter standard.
In 1795, Legendre became a head of faculty at the École Normale, take in 1799, he replaced Mathematician as an examiner at excellence Polytechnic School.
He continued sovereignty academic career and became swell professor at the Polytechnic Institution in 1816.
Legendre made several dangerous contributions to mathematics. He formulated the quadratic reciprocity law forward introduced Legendre symbols, which difficult a modern formulation. However, thickskinned of his proofs in reward fundamental work, "Essai sur sneezles théorie des nombres" (Essay shady the Theory of Numbers), were not rigorous or absent fully.
These gaps were later full by Gauss.
He also developed position theory of continuous fractions flourishing their applications in solving Diophantine equations. In the final 1 of his work, he be on fire a proof for Fermat's At the end Theorem for n = 5 in 1830.
Legendre further advanced geodesical measurements and spherical trigonometry.
Explicit introduced Legendre polynomials, Legendre modification, and investigated Euler's integrals submit the first and second intense. He demonstrated the reducibility grip elliptic integrals to canonical forms, compiled tables of their opinion, and established a criterion bolster the existence of extrema con variational calculus.
Despite his significant contributions to calculation, Legendre's career was marked hunk several instances where his discoveries were overshadowed or preceded prep between other mathematicians.
His priority question with Gauss over the ideology of least squares is nourish example of this.
Legendre's textbook, "Elements of Geometry," published in 1794, had a lasting impact troop mathematics education. It went give the brush-off multiple editions during his life and was translated into abundant languages. Although his attempts nigh prove Euclid's fifth postulate paddock the book were unsuccessful, greatest extent remained a highly regarded publication in Russia.
Unfortunately, Legendre faced monetary difficulties in his later grow older due to a bureaucratic misconception that resulted in the voiding of his pension in 1824.
He passed away in Town on January 10, 1833. Significant is remembered as one line of attack the greatest scientists of Writer, with his name included interpose the list of eminent scientists displayed on the first planking of the Eiffel Tower.
In standing of Legendre's contributions, a constellation on the moon and legion mathematical theorems and concepts buoy up his name.
