Fermat's principle, also known as the principle of least time, is the link between ray optics and wave optics. Fermat's principle states that the path...

which he used to prove Fermat's right triangle theorem which includes as a corollary Fermat's Last Theorem for the case n = 4. Fermat developed the two-square...

mathematician Pierre de Fermat engendered many theorems. Fermat's theorem may refer to one of the following theorems: Fermat's Last Theorem, about integer...

Such solutions are known as geodesics. A related problem is posed by Fermat's principle: light follows the path of shortest optical length connecting two...

optico-mechanical analogy is closely related to Fermat's principle and thus to the Huygens–Fresnel principle. Fermat's principle states that the rays between wavefronts...

Fermat's Last Theorem is a popular science book (1997) by Simon Singh. It tells the story of the search for a proof of Fermat's Last Theorem, first conjectured...
