Let's make a list of all worthwhile inventions that come from France.

I'll wait.

The 1751 machine is what became the modern lathe.

Your contribution to this thread could easily be interpreted as an insult to the French people and culture. I'd like to think that it wasn't meant that way but you might want to think about offering some clarification of what you meant.

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...

Pasteurization
Canned food
The rabies vaccine
The germ theory of disease
The monoplane

Lets not forget the Razor of Democracy itself, Dr Guillotine's invention...

that's just off the top of my head...

...also Democracy and Existentialism...

Can't believe I forgot this..

The Jaquard Loom, which is arguably the foundational concept of modern CNC manufacturing.

Fun fact: US measurement standards are actually defined in metric units. 8:51 video from a visit to the National Institute of Standards and Technology:

And then you've this: The stone or stone weight (abbreviation: st.) is an English and imperial unit of mass now equal to 14 pounds (approximately 6.35 kg). 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.
