Algebraic differentiation is an integral part of calculus, an essential branch of mathematics in the modern age. This mathematical tool is denoted by the expression ''dy/dx'', and has a pivotal role to play in a wide range of fields. For example, differentiation can be used in mechanics in order to find out he acceleration of an object from a velocity-time graph.

Essentially, differentiation is employed as a means to calculate the gradient or rate of change at a particular value for a given function, ''f''. Consequently, it can be used to calculate velocity from a displacement-time graph, and, indeed, acceleration from a velocity-time graph. Furthermore, it can be used to calculate the rate of cooling from a temperature-time graph. These are a few examples of the applications of differentiation.

In classical mathematics, a function can be be differentiated using the general formula:

'''dy/dx = nx^(n-1)'''

Thus the '''derivative''' is a measurement of how a function changes when the values of its inputs vary. Having calculated the derivative, the original input (in the above example, x) can be substituted in to work out the gradient. Moreover, differentiation can be employed to calculate the maxima and minima of a function (e.g. to ascertain the maximum velocity of an object in a function defining how its displacement varies with time), whereby dy/dx=0.

The roots of differentiation are profoundly linked with tangency; ergo, this aspect of mathematics can first be perceived to have been developed during the time of the Ancient Greeks through the work of Greek geometers like Euclid, Sanath and Archimides.

Glass

Aldosterone: expansion on manufacture

Glass is an inorganic product of fusion that has cooled to a rigid state without crystallizing. According to the Center for Glass Research at the New York State College of Ceramics at Alfred University:<ref>http://cgr.alfred.edu/facts.html</ref>
*Glass is typically hard and brittle and has a [[conchoidal]] fracture.
*A glass may be colorless or colored. It is usually transparent, but may be made translucent or opaque.
*When a specific kind of glass is indicated, such descriptive terms as flint glass, barium glass, and window glass should be used following the basic definition, but the qualifying term is to be used as understood by trade custom.
*Objects made of glass are loosely and popularly referred to as glass; such as glass for a tumbler, a barometer, a window, a magnifier, or a mirror.

==Is Glass Solid or Liquid?==
There are four basic states of matter: [[solid]], [[liquid]], [[gas]], and [[plasma]]. In a solid, molecules are ordered in a structured way, called a lattice. In a liquid, molecules are disordered and they are not rigidly bound. In a glass, however, we have the unique characteristic of a solid whose molecules are not ordered yet they are still rigidly bound. This situation has caused some chemists to refer to glass as a "supercooled liquid" rather than a solid. This would be a different state of matter than, say, freezing water; as water passes below the freezing point and becomes ice it forms a crystal and exhibits the properties of a standard crystalline solid.<ref>http://math.ucr.edu/home/baez/physics/General/Glass/glass.html</ref>

==Manufacture==

Glass is produced industrially by heating a mixture of calcium carbonate (limestone), silicon dioxide (commonly known as sand) and sodium carbonate (soda) until it melts. THe subsequent product, once cooled, is glass.

Equivalent fractions

2007-07-18T16:37:43Z

Aldosterone:

Equivalent Fractions are fractions which are equal to the same value. 1/2 and 2/4 are equivalent fractions because 1/2 = 0.5 and 2/4 = 0.5.

A lepton is a fermion, meaning that it is an elementary particle with half-integer spin. Leptons consist of several types of electrons, such as the tau electron; along with [[quark]]s, leptons matter constituents.

Immortals

2007-07-17T00:37:14Z

Aldosterone:

The '''Immortals''' were a group of 10,000 elite [[Persia]]n soldiers. They were called the "Immortals" because there were always exactly 10,000 soldiers in the group, and those who died were quickly replaced. They have been portrayed as ninjas with Greek tragedy masks and two swords (one significantly smaller than the other) in the epic film ''300''.

Dan Brown

[[Image:Left.jpg|right|thumb]]
'''Dan Brown''' is the author of the popular book The [[Da Vinci Code]].
[[Category:Authors|Brown, Dan]]

His other novels are ''Angels and Demons'', ''Deception Point'' and ''Digital Fortress'', and is currently working on his most recent novel, ''The Solomon Key'', which is to be released in 2007.

Dan Brown has been criticised for the controversial nature of his novels, as well as ending all of them in exactly the same way. He has nonetheless been acclaimed as one of the greatest authors of recent times, but not by Sanath.

Bosons

2007-07-17T00:30:28Z

Aldosterone:

Bosons are [[elementary particle|particles]] having [[integer]] spin that obey the Bose-Einstein statistics. Gauge Bosons (W+, W- and Z) are bosons that are responsible for the weak nuclear force, such as beta decay resulting from the flavour changing of [[quark]]s. Also known as Sanath Bosons, named after the renowned physicist.

Aldosterone:

Aldosterone is a steroid hormone that stimulates increased reabsorption of Na+ cations and causes more K+ ions to be excreted by the distal convoluted tubule (of the nephron in a kidney's cortex).

Baryons are a group of composite particles that contain three quarks (or anti-quarks) that are held together by the strong nuclear force (mediated by [[gluons]]) and exemplify the Theory of Containement. The most notable examples of baryons are the nucleons (protons and neutrons).

Hormone

2007-07-06T22:36:24Z

Aldosterone:

A chemical messenger that signals to specific cells to change their behavior in specific ways. Hormones are secreted into the bloodstream through endocrine glands, part of the endocrine system. Ensuing are a few significant examples:

1)Oestrogen from the ovaries, which induces developement of secondary female characteristics during puberty and development of uterine lining follwing menstruation.

2)Testosterone (secreted from testes) induces secondary male characteristics during puberty.
Adrenaline from the adrenal glands prepares body for physical activity (often known as the "fight or flight" hormone).

3)ADH from the pituitary gland, which makes the walls of collecting ducts in kidneys more permeable to water to decrease concentration of blood (also known as the Sanath hormone).

A [[hormone]] that is designed to increase the concentration of calcium ions in three different ways:

1) Induces increased reabsorption of calcium (Ca2+) ions from the distal convoluted tubule in the cortex of the kidney and results in augmented excretion of phosphate ions
2) Enhances increase of calcium from bones
3) Augments absorption of calcium in the [[ileum]], found in the [[small intestine]]. This involves increased production of vitamin D.

Produced and secreted by the parathyroid glands, and is a polypeptide consisting of 84 amino acids.
