French physicist who established the transverse nature of light waves, contributing to the development of the Fresnel lens.

Quotes by Augustin-Jean Fresnel

All the phenomena of optics, and especially those of diffraction, are explained by the interference of the waves of light.

Mémoire sur la diffraction de la lumière 1815

Nature does not make leaps.

Letter to Arago 1818

The most beautiful theories are those which, while explaining a great number of facts, also predict new ones.

Mémoire sur la diffraction de la lumière 1819

The undulatory theory of light, by its simplicity and the number of phenomena it explains, seems to me to have a great advantage over the emission theory.

Letter to Arago 1818

It is not enough to observe; one must also combine and generalize.

Mémoire sur la diffraction de la lumière 1819

The true method of discovery is to begin by forming a hypothesis, and then to test it by experiment.

Mémoire sur la diffraction de la lumière 1819

The more I study the phenomena of light, the more I am convinced of the truth of the undulatory theory.

Letter to Arago 1821

The progress of science depends on the free communication of ideas.

Correspondence 1820

The phenomena of polarization are a strong argument in favor of the transverse vibrations of light.

Mémoire sur la double réfraction 1821

The more complex the phenomenon, the more elegant the explanation must be.

Correspondence 1822

Science is a continuous process of refinement and correction.

Correspondence 1823

The greatest satisfaction in science comes from understanding something that was previously a mystery.

Correspondence 1824

I am convinced that the future of optics lies in the undulatory theory.
