And the prism was shaped like a prism, and the light signals would come in, and they'd be split by the prism.— Democracy Now!
The center of gravity of a prism is the center of its axis.— Geometrical Solutions Derived from Mechanics; a Treatise of Archimedes
The form of instrument which Fraunhofer adopted for this work, in which the prism was placed outside the object glass of the telescope, has not been much used until within the last few years, owing to the difficulty of obtaining prisms of large dimensions (for it is obvious that the prism ought to be as large as the object glass if the full power of the latter is to be made use of), but this is the simplest form of spectroscope for observing spectra of objects of no sensible angular diameter, like the fixed stars.— The Story of the Heavens
