Mining

Mining

Mining is the process of digging things out of the ground. It is the act, process, or industry of extracting ores, coal, etc. Any material that cannot be grown must be mined. Mining things from the ground is called extraction. Mining can include extraction of metals and minerals, like coal, diamo.....

Angular Velocity – in Physics

Angular Velocity – in Physics

In physics, the angular velocity specifies the angular speed at which an object is rotating along with the direction in which it is rotating. It applies to objects that move along a circular path. It is less common than linear velocity because it only applies to objects that are moving along a ci.....

The half-life of an Element

The half-life of an Element

The half-life of an Element The half-life of a substance is the time it takes for half of the substance to decay. The term half-life is defined as the time it takes for one-half of the atoms of a radioactive material to disintegrate. The word “half-life” was first used when talking ab.....

Statistical Mechanics in Physics

Statistical Mechanics in Physics

Statistical mechanics is the application of probability theory, which includes mathematical tools for dealing with large populations, to the field of mechanics, which is concerned with the motion of particles or objects when subjected to a force. It is a branch of physics that combines the princi.....

Bose–Einstein Condensation (BEC)

Bose–Einstein Condensation (BEC)

Bose-Einstein Condensation (BEC) Bose-Einstein condensation (BEC) in networks is a phase transition observed in complex networks that can be described with the same mathematical model as that explaining Bose-Einstein condensation in physics. It is a state of matter in which separate atoms or suba.....

Witherite

Witherite

Witherite Definition Witherite (BaCO3) is a white, grey, or yellowish mineral consisting of barium carbonate in orthorhombic crystalline form: occurs in veins of lead ore. Witherite crystallizes in the orthorhombic system and virtually always is twinned. The specific gravity is 4.3, which is high.....

Stellerite

Stellerite

Stellerite Definition Stellerite is an uncommon member of the zeolite group, and is very similar in structure and formation to Stilbite, with a general formula of Ca[Al2Si7O18]·7H2O. It is named after Georg Wilhelm Steller (1709–1746) a famous German explorer, physician, and zoologist. Like mo.....

Stilbite

Stilbite

Stilbite Definition Stilbite is a white or yellow zeolite mineral consisting of hydrated calcium sodium aluminium silicate, often in the form of sheaves of monoclinic crystals. Since its original classification, Stilbite was always regarded as a single mineral species with a slightly variable ele.....

Zeolite

Zeolite

Zeolite Definition Zeolite is any of a family of hydrous aluminum silicate minerals, whose molecules enclose cations of sodium, potassium, calcium, strontium, or barium. Zeolites are usually white or colorless, but they can also be red or yellow. They are characterized by their easy and reversibl.....

Hematite

Hematite

Hematite Definition Hematite is a reddish-brown to silver-gray metallic mineral. Its chemical formula: Fe2O3. Hematite occurs as rhombohedral crystals, as reniform (kidney-shaped) crystals, or as fibrous aggregates in igneous, metamorphic, and sedimentary rocks. It is the most abundant ore of iro.....
