Power scaling — of a laser is increasing its output power without changing the geometry, shape, or principle of operation. Power scalability is considered an important advantage in a laser design.Usually, power scaling requires a more powerful pump source,… … Wikipedia
Power of a point — Figure 1. Illustration of the power of point P in the circle centered on the point O. The distance s is shown in orange, the radius r is shown in blue, and the tangent line segment PT is shown in red. In elementary plane geometry, the power of a… … Wikipedia
Power center (geometry) — The radical center (orange point) is the center of the unique circle (also orange) that intersects three given circles at right angles. In geometry, the power center of three circles, also called the radical center, is the intersection point of… … Wikipedia

Differential geometry of surfaces — Carl Friedrich Gauss in 1828 In mathematics, the differential geometry of surfaces deals with smooth surfaces with various additional structures, most often, a Riemannian metric. Surfaces have been extensively studied from various perspectives:… … Wikipedia
Finite geometry — A finite geometry is any geometric system that has only a finite number of points. Euclidean geometry, for example, is not finite, because a Euclidean line contains infinitely many points, in fact precisely the same number of points as there are… … Wikipedia
Memory geometry — In the design of modern personal computers, memory geometry describes the internal structure of random access memory. Memory geometry is of concern to consumers upgrading their computers, since older memory controllers may not be compatible with… … Wikipedia
