Esophoria is an eye condition involving inward deviation of the eye, usually due to extra-ocular muscle imbalance. It is a type of heterophoria. Cause. Causes include: Refractive errors; Divergence insufficiency; Convergence excess; this can be due to nerve, muscle, congenital or mechanical anomalies.
Prism dioptres. Prism correction is commonly specified in prism dioptres, a unit of angular measurement that is loosely related to the dioptre. Prism dioptres are represented by the Greek symbol delta (Δ) in superscript. A prism of power 1 Δ would produce 1 unit of displacement for an object held 100 units from the prism. [2]
Geometry Dash Subzero. Geometry Dash is a side-scrolling music platforming game series developed by Robert Topala. The game was released on 13 August 2013 on iOS and Android, and the Windows and macOS versions on 22 December 2014. In Geometry Dash, players control the movement of an icon and navigate music-based levels while avoiding obstacles ...
Non-Euclidean geometry is an example of a scientific revolution in the history of science, in which mathematicians and scientists changed the way they viewed their subjects. [24] Some geometers called Lobachevsky the " Copernicus of Geometry" due to the revolutionary character of his work.
In mathematics, a spherical coordinate system is a coordinate system for three-dimensional space where the position of a given point in space is specified by three numbers, ( r, θ, φ ): the radial distance of the radial line r connecting the point to the fixed point of origin (which is located on a fixed polar axis, or zenith direction axis ...
D nh is the symmetry group for a regular n-sided prism and also for a regular n-sided bipyramid. D nd is the symmetry group for a regular n-sided antiprism, and also for a regular n-sided trapezohedron. D n is the symmetry group of a partially rotated prism. n = 1 is not included because the three symmetries are equal to other ones:
In geometry, a Euclidean plane isometry is an isometry of the Euclidean plane, or more informally, a way of transforming the plane that preserves geometrical properties such as length. There are four types: translations, rotations, reflections, and glide reflections (see below § Classification ). The set of Euclidean plane isometries forms a ...
