HighlightsA brief glimpse into the past
Team, Place & City Details
Samtredia
Samtredia is a town in Imereti, Georgia, lying in a lowland between the rivers Rioni and Tskhenis-Tsqali, 244 km (152 mi) west of the capital Tbilisi, and 27 km (17 mi) west of Georgia's second largest city Kutaisi. Georgia’s most important roads and railways converge there, making Samtredia the country’s vital transport hub.
Samtredia Municipality
Samtredia is a district of Georgia, in the region of Imereti. Its main town is Samtredia.
Spherical coordinate system
In mathematics, a spherical coordinate system is a coordinate system for three-dimensional space where the position of a point is specified by three numbers: the radial distance of that point from a fixed origin, its polar angle measured from a fixed zenith direction, and the azimuthal angle of its orthogonal projection on a reference plane that passes through the origin and is orthogonal to the zenith, measured from a fixed reference direction on that plane. It can be seen as the three-dimensional version of the polar coordinate system.
Spherical harmonics
In mathematics and physical science, spherical harmonics are special functions defined on the surface of a sphere. They are often employed in solving partial differential equations in many scientific fields.
Spherical Earth
The earliest documented mention of the spherical Earth concept dates from around the 5th century BC, when it was mentioned by ancient Greek philosophers. It remained a matter of speculation until the 3rd century BC, when Hellenistic astronomy established the spherical shape of the Earth as a physical fact and calculated the Earth's circumference.
Spherical trigonometry
Spherical trigonometry is the branch of spherical geometry that deals with the relationships between trigonometric functions of the sides and angles of the spherical polygons defined by a number of intersecting great circles on the sphere. Spherical trigonometry is of great importance for calculations in astronomy, geodesy and navigation.
Spherical cap
In geometry, a spherical cap or spherical dome is a portion of a sphere or of a ball cut off by a plane. It is also a spherical segment of one base, i.e., bounded by a single plane.
Sparring
Sparring is a form of training common to many combat sports. Although the precise form varies, it is essentially relatively 'free-form' fighting, with enough rules, customs, or agreements to minimize injuries.
Sparidae
The Sparidae are a family of fish in the order Perciformes, commonly called sea breams and porgies. The sheepshead, scup, and red seabream are species in this family.
Spherical tokamak
A spherical tokamak is a type of fusion power device based on the tokamak principle. It is notable for its very narrow profile, or aspect ratio.
Sparisoma aurofrenatum
Sparisoma aurofrenatum, common names the redband parrotfish, gutong, rainbow parrot, black parrot, and blisterside, is a species of parrotfish.
Spherical wave transformation
Spherical wave transformations leave the form of spherical waves as well as the laws of optics and electrodynamics invariant in all inertial frames. They were defined between 1908 and 1909 by Harry Bateman and Ebenezer Cunningham, with Bateman giving the transformation its name.
