Louis Georges Gouy
Louis Georges Gouy (February 19, 1854 – January 27, 1926)[1] was a French physicist. He is the namesake of the Gouy balance, the Gouy–Chapman electric double layer model (which is a relatively successful albeit limited model that describes the electrical double-layer which finds applications in vast areas of studies from physical chemistry to biophysics) and the Gouy phase.
Louis Georges Gouy
Gouy was born at Vals-les-Bains, Ardèche in 1854. He became a correspondent of the Académie des sciences in 1901, and a member in 1913.
Topics investigated
His principal scientific work was related to the following subjects:
- The propagation velocity of light waves in dispersive media.
- Propagation of spherical waves of small radius.
- Distant diffraction (angles of dispersion reaching 150°)
- Electrostatics: Inductive capacity of dielectrics
- Surface charge
- Effect of the magnetic field on the discharge in rarefied gases
- Electrocapillarity
- Emission capacity of absorbent of the coloured flames
- Brownian motion
- Measurement of magnetic susceptibility of transition metal complexes with Gouy balance
- The gouy phase shift, a feature of Gaussian beams.

gollark: Since you're me, this is isomorphic to an admission that I do.
gollark: As me, you have authority over time scheduling, so you can reassign 2026 to 2022 if you want.
gollark: 2026.
gollark: It is not fully independent.
gollark: What if Olivia picks this theme?
