Anyway, on to a response to your request...
France has given us some of the most influential mathematicians who have provided much of the analytic framework on which modern developments are based. Here is a partial list...
Blaise Pascal - projective geometry, mechanical calculator, Pascal's law, Pascal's triangle
Pierre Fermat - difference quotient (precursor to differential calculus), Fermat's last theorem, Fermat's principle
Jean-Baptiste Fourier - Fourier series, Fourier transform, greenhouse effect
René Descartes - analytical geometry, Cartesian coordinates, rationalism
Pierre-Simon Laplace - Laplace's equation, Laplace transform
The work of many of these mathematicians extends into the scientific world. In addition, there are many key French scientists as this list shows...

The stone continues in customary use in Britain and Ireland for body weight, but was prohibited for commercial use in the United Kingdom by the Weights and Measures Act of 1985.
