Augustin-Jean Fresnel (1788–1827) was a pioneering French physicist and civil engineer whose "piece" of history is the revolutionary . Known as the "invention that saved a million ships," his lens design replaced heavy, inefficient mirrors with a lightweight, stepped glass structure that could project light more than 20 miles out to sea. Beyond maritime safety, he established the wave theory of light , providing the mathematical proof that light travels as transverse waves rather than particles. 🌊 The "Invention That Saved a Million Ships"
