Pierre de Fermat

1. Fermat's Last Theorem

No three positive integers fit this equation for \(n > 2\).

$$ a^n + b^n = c^n $$

2. Fermat's Little Theorem

A fundamental property of prime numbers.

$$ a^{p-1} \equiv 1 \pmod{p} $$

3. Fermat's Principle

Light travels between two points along the path of least time.

$$ \delta \int_{A}^{B} dt = 0 $$
