WebAccording to a talk by Domingo Luna around 1985, the term spherical variety is not derived from spheres, at least not directly. Firstly, spheres are way too atypical, e.g., their compactification theory is pretty pointless. Secondly, in invariant theory circles spheres are called quadrics anyway. Webspherical. having the form of a sphere; globular. formed in or on a sphere, as a figure. of or relating to a sphere or spheres. pertaining to the heavenly bodies, or to their supposed …
Common Optical Defects in Lens Systems (Aberrations) - Olympus
WebSpherical aberration is inherent in the basic shape of a spherical surface and is independent of alignment or manufacturing errors; in other words, a perfectly designed and manufactured spherical lens will still inherently exhibit spherical aberration. WebSomething spherical is like a sphere in being round, or more or less round, in three dimensions. Apples and oranges are both spherical, for example, even though they're … english 1021
