Spherical aberration — shape of lenses and mirrors. This is an important effect, as spherical shapes are much easier to produce than aspherical and so most lenses have spherical shapes. Positive spherical aberration means peripheral rays are bent too much. Negative… … Wikipedia
non-Newtonian fluid — A fluid in which the viscosity varies depending upon the shear stress. The effect can arise because of alignment of non spherical molecules as flow is established or because of suspended deformable particles as in blood … Dictionary of molecular biology
Spherical trigonometry — Spherical triangle Spherical trigonometry is a branch of spherical geometry which deals with polygons (especially triangles) on the sphere and the relationships between the sides and the angles. This is of great importance for calculations in… … Wikipedia
Spherical geometry — is the geometry of the two dimensional surface of a sphere. It is an example of a non Euclidean geometry. Two practical applications of the principles of spherical geometry are navigation and astronomy.In plane geometry the basic concepts are… … Wikipedia
Spherical multipole moments — are the coefficients in a series expansionof a potential that varies inversely with the distance R to a source, i.e., as frac{1}{R}. Examples of such potentials are the electric potential, the magnetic potential and the gravitational… … Wikipedia

Non-orientable wormhole — In wormhole theory, a non orientable wormhole is a wormhole connection that appears to reverse the chirality of anything passed through it. It is related to the twisted connections normally used to construct a Möbius strip or Klein bottle. In… … Wikipedia
Spherical 3-manifold — In mathematics, a spherical 3 manifold M is a 3 manifold of the form M = S3 / Γ where Γ is a finite subgroup of SO(4) acting freely by rotations on the 3 sphere S3. All such manifolds are prime, orientable, and closed. Spherical 3 manifolds are… … Wikipedia
