The common prism is a triangular piece of cut glass used to break white light up into its constituent colors. These prisms are often found in middle-school science classrooms. For a famous example of a prism at work, check out the cover of Pink Floyd's Dark Side of the Moon. Visible light is composed of a spectrum of different colors, each with a distinct wavelength. A prism separates colors by bending them by different degrees, much like droplets of water vapor refract sunlight into a rainbow. Metaphorically,
a prism can refer anything that is used to look at the world differently. Like rose-colored glasses, for instance. Or a new psychiatric theory. Or a friend with interesting opinions. Choose your prisms wisely.
