**Pierre de Fermat** was a French Mathematician who is famous for early developments on infinitesimal calculus. He is known for his technique of adequality. He also discovered the original method of finding the smallest and the greatest ordinates of curved lines. He is also famous for many of his other research works on number theory.

He also made great contributions in the field of probability, geometry, optics, and analytics. He is famous for his Fermat’s Last Theorem in number theory and Fermat’s principle for light propagation.

## Quotes By Pierre de Fermat

Few of the famous Quotes by Pierre de Fermat:

I have discovered a truly remarkable proof of this theorem, which this margin is too small to contain.

There is scarcely anyone who states purely arithmetical questions, scarcely any who understands them. Is this not because arithmetic has been treated up to this time geometrically rather than arithmetically.

I propose this theorem to be proved or a problem to be solved. If they succeed in discovering the proof or solution, they will acknowledge that questions of this kind are not inferior to the more celebrated ones from geometry either for depth or difficulty or method of proof.

The result of my work has been the most extraordinary, the most unforeseen, and the happiest, that ever was; for, after having performed all the equations, multiplications, antitheses, and other operations of my method, and having finally finished the problem, I have found that my principle gives exactly and precisely the same proportion for the refractions which Monsieur Descartes has established.

## Other Mathematicians Talking about Pierre de Fermat

Great Mathematicians and Scientists like Isaac Newton, Paul Tannery, J. Lagrange, and many others praised Pierre works.

I had a hint of this method from Fermat’s way of drawing tangents, and by applying it to abstract equations, directly and invertedly, I made it general.

Isaac Newton

Fermat is… honored with the invention of the differential calculus on account of his method of maxima and minima and of tangents, which, of the prior processes, is, in reality, the nearest to the algorithm of Leibniz; one could with equal justice, attribute to him the invention of the integral calculus.

Paul Tannery

One may regard Fermat as the first inventor of the new calculus

J. Lagrange

Fermat applied his method of tangents to many difficult problems. The method has the form of the now-standard method of differential calculus, though it begs the difficult theory of limits entirely.

Morris Kline

Fermat invented the calculus.

Florian Cajori

Fermat had recourse to the principle of the economy of nature.

Carl B. Boyer

Just like Fermat, there is a mathematician from french whose work is famous worldwide. He is Pierre-Simon Laplace.
