E₈ lattice — In mathematics, the E8 lattice is a special lattice in R8. It can be characterized as the unique positive definite, even, unimodular lattice of rank 8. The name derives from the fact that it is the root lattice of the E8 root system. The normIn… … Wikipedia

Reciprocal lattice — In physics, the reciprocal lattice of a lattice (usually a Bravais lattice) is the lattice in which the Fourier transform of the spatial function of the original lattice (or direct lattice) is represented. This space is also known as momentum… … Wikipedia

Observer (special relativity) — The term observer in special relativity refers most commonly to an inertial reference frame. Less often it may refer to an arbitrary non inertial reference frame; in particular, a Rindler frame is sometimes called an accelerating observer . In… … Wikipedia
