Why does Brewster's angle matter? This principle is one of the building blocks physicists use to explain the world. Without it, a whole class of phenomena would have no mathematical description. Engineers, chemists, and astronomers all rely on it.

Background: Brewster's angle Brewster's angle (also known as the polarization angle) is the angle of incidence at which light with a particular polarization is perfectly transmitted through a transparent dielectric surface, with no reflection. When unpolarized light is incident at this angle, the light that is reflected from the surface is perfectly polarized. The angle is named after the Scottish physicist Sir David Brewster (1781–1868).
