A crystal is a solid where the atoms form a periodic arrangement. ( Quasicrystals are an exception, see below ). Not all solids are crystals. For example, when liquid water starts freezing, the phase change begins with small ice crystals that grow until they fuse, forming a polycrystalline structure.
1990s. The band was formed in January 1993, by bassist and vocalist Dejan Gvozden and guitarist Željko Markuš, who, having performed blues and rock standards in Belgrade cafes, were joined by drummer Dejan Kostić. By the time the band had written their first hit song "Dva metra" ("Two Meters"), for which the music video was directed by ...
Aquamarine (gem) Aquamarine is a pale-blue to light-green variety of the beryl family, [2] with its name relating to water and sea. [3] The color of aquamarine can be changed by heat, with a goal to enhance its physical appearance (though this practice is frowned upon by collectors and jewelers). [4] It is the birth stone of March.
Ice crystal. A close-up of growing ice crystals displaying typical hexagonal symmetry. Ice crystals are solid ice in symmetrical shapes including hexagonal columns, hexagonal plates, and dendritic crystals. [1] Ice crystals are responsible for various atmospheric optic displays and cloud formations. [1] [2]

Time. In condensed matter physics, a time crystal is a quantum system of particles whose lowest-energy state is one in which the particles are in repetitive motion. The system cannot lose energy to the environment and come to rest because it is already in its quantum ground state.
Recept. " Recept " (pronounced / ˈriːˌsɛpt /) is a term used in the work of 19th-century psychologist George Romanes to refer to an idea that is formed by the repetition of percepts (i.e., successive percepts of the same object). [1] The idea is similar to that of concatenated impressions, as seen in the work of David Hume.
A cholesteric liquid-crystal display (ChLCD) is a display containing a liquid crystal with a helical structure and which is therefore chiral. Cholesteric liquid crystals are also known as chiral nematic liquid crystals. They organize in layers with no positional ordering within layers, but a director axis which varies with layers.
