Quark A quark (/kwɔːrk, kwɑːrk/) is a type of elementary particle and a fundamental constituent of matter. Quarks combine to form composite particles called hadrons, the most stable of which are protons and neutrons, the components of atomic nuclei.[1] Due to a phenomenon known as color confinement, quarks are never directly observed or found in isolation; they can be found only within hadrons, such as baryons (of which protons and neutrons are examples) and mesons.[2][3] For this reason, much of what is known about quarks has been drawn from observations of the hadrons themselves. Quarks have various intrinsic properties, including electric charge, mass, color charge, and spin [...More...]  "Quark" on: Wikipedia Yahoo 

Radio Astronomy Radio astronomy Radio astronomy is a subfield of astronomy that studies celestial objects at radio frequencies. The first detection of radio waves from an astronomical object was in 1932, when Karl Jansky Karl Jansky at Bell Telephone Laboratories observed radiation coming from the Milky Way. Subsequent observations have identified a number of different sources of radio emission. These include stars and galaxies, as well as entirely new classes of objects, such as radio galaxies, quasars, pulsars, and masers. The discovery of the cosmic microwave background radiation, regarded as evidence for the Big Bang Big Bang theory, was made through radio astronomy. Radio astronomy Radio astronomy is conducted using large radio antennas referred to as radio telescopes, that are either used singularly, or with multiple linked telescopes utilizing the techniques of radio interferometry and aperture synthesis [...More...]  "Radio Astronomy" on: Wikipedia Yahoo 

Plasma (physics) Plasma (from Ancient Greek Ancient Greek πλάσμα, meaning 'moldable substance'[1]) is one of the four fundamental states of matter, and was first described by chemist Irving Langmuir[2] in the 1920s.[3]. Unlike the other three states, solid, liquid, and gas, plasma does not exist freely on the Earth's surface under normal conditions [...More...]  "Plasma (physics)" on: Wikipedia Yahoo

Numerical Integration In numerical analysis, numerical integration constitutes a broad family of algorithms for calculating the numerical value of a definite integral, and by extension, the term is also sometimes used to describe the numerical solution of differential equations. This article focuses on calculation of definite integrals. The term numerical quadrature (often abbreviated to quadrature) is more or less a synonym for numerical integration, especially as applied to onedimensional integrals. Some authors refer to numerical integration over more than one dimension as cubature;[1] others take quadrature to include higherdimensional integration. The basic problem in numerical integration is to compute an approximate solution to a definite integral ∫ a b f ( x ) d x displaystyle int _ a ^ b f(x),dx to a given degree of accuracy [...More...]  "Numerical Integration" on: Wikipedia Yahoo 

Graph Theory In mathematics, graph theory is the study of graphs, which are mathematical structures used to model pairwise relations between objects. A graph in this context is made up of vertices, nodes, or points which are connected by edges, arcs, or lines. A graph may be undirected, meaning that there is no distinction between the two vertices associated with each edge, or its edges may be directed from one vertex to another; see Graph (discrete mathematics) Graph (discrete mathematics) for more detailed definitions and for other variations in the types of graph that are commonly considered [...More...]  "Graph Theory" on: Wikipedia Yahoo 

Theory Of Relativity The theory of relativity usually encompasses two interrelated theories by Albert Einstein: special relativity and general relativity.[1] Special relativity Special relativity applies to elementary particles and their interactions, describing all their physical phenomena except gravity. General relativity General relativity explains the law of gravitation and its relation to other forces of nature.[2] It applies to the cosmological and astrophysical realm, including astronomy.[3] The theory transformed theoretical physics and astronomy during the 20th century, superseding a 200yearold theory of mechanics created primarily by Isaac Newton.[3][4][5] It introduced concepts including spacetime as a unified entity of space and time, relativity of simultaneity, kinematic and gravitational time dilation, and length contraction [...More...]  "Theory Of Relativity" on: Wikipedia Yahoo 

Kinematics Kinematics Kinematics is a branch of classical mechanics that describes the motion of points, bodies (objects), and systems of bodies (groups of objects) without considering the mass of each or the forces that caused the motion.[1][2][3] Kinematics, as a field of study, is often referred to as the "geometry of motion" and is occasionally seen as a branch of mathematics.[4][5][6] A kinematics problem begins by describing the geometry of the system and declaring the initial conditions of any known values of position, velocity and/or acceleration of points within the system. Then, using arguments from geometry, the position, velocity and acceleration of any unknown parts of the system can be determined. The study of how forces act on masses falls within kinetics. For further details, see analytical dynamics. Kinematics Kinematics is used in astrophysics to describe the motion of celestial bodies and collections of such bodies [...More...]  "Kinematics" on: Wikipedia Yahoo 

Sun The Sun Sun is the star at the center of the Solar System. It is a nearly perfect sphere of hot plasma,[14][15] with internal convective motion that generates a magnetic field via a dynamo process.[16] It is by far the most important source of energy for life on Earth. Its diameter is about 1.39 million kilometers, i.e. 109 times that of Earth, and its mass is about 330,000 times that of Earth, accounting for about 99.86% of the total mass of the Solar System.[17] About three quarters of the Sun's mass consists of hydrogen (~73%); the rest is mostly helium (~25%), with much smaller quantities of heavier elements, including oxygen, carbon, neon, and iron.[18] The Sun Sun is a Gtype mainsequence star Gtype mainsequence star (G2V) based on its spectral class. As such, it is informally referred to as a yellow dwarf [...More...]  "Sun" on: Wikipedia Yahoo 

H.O. Lancaster Henry Oliver Lancaster AO FAA,[1] (1 February 1913, Sydney – 2 December 2001, Sydney), also known as "HOL", was an Australian mathematical statistician and was Foundation Professor of Mathematical Statistics at the University of Sydney. After initial actuarial and accounting studies, his early studies and career were in medicine, particularly in pathology where he employed a strong element of statistical analysis. From 1946 to 1959 he worked in the area of tropical medicine in Sydney and London. From 1959 to 1978 he was Professor of Mathematical Statistics at the University of Sydney, at which time he retired.[2][3][4] References[edit]^ "Officer of the Order of Australia".

Number Theory Number Number theory, or in older usage arithmetic, is a branch of pure mathematics devoted primarily to the study of the integers. It is sometimes called "The Queen of Mathematics" because of its foundational place in the discipline.[1] Number Number theorists study prime numbers as well as the properties of objects made out of integers (e.g., rational numbers) or defined as generalizations of the integers (e.g., algebraic integers). Integers can be considered either in themselves or as solutions to equations (Diophantine geometry). Questions in number theory are often best understood through the study of analytical objects (e.g., the Riemann zeta function) that encode properties of the integers, primes or other numbertheoretic objects in some fashion (analytic number theory) [...More...]  "Number Theory" on: Wikipedia Yahoo 

Statistics Statistics Statistics is a branch of mathematics dealing with the collection, analysis, interpretation, presentation, and organization of data.[1][2] In applying statistics to, for example, a scientific, industrial, or social problem, it is conventional to begin with a statistical population or a statistical model process to be studied. Populations can be diverse topics such as "all people living in a country" or "every atom composing a crystal". Statistics Statistics deals with all aspects of data including the planning of data collection in terms of the design of surveys and experiments.[1] See glossary of probability and statistics. When census data cannot be collected, statisticians collect data by developing specific experiment designs and survey samples. Representative sampling assures that inferences and conclusions can reasonably extend from the sample to the population as a whole [...More...]  "Statistics" on: Wikipedia Yahoo 

Stationary Process In mathematics and statistics, a stationary process (a.k.a. a strict(ly) stationary process or strong(ly) stationary process) is a stochastic process whose unconditional joint probability distribution does not change when shifted in time. Consequently, parameters such as mean and variance, if they are present, also do not change over time. Since stationarity is an assumption underlying many statistical procedures used in time series analysis, nonstationary data is often transformed to become stationary. The most common cause of violation of stationarity is a trend in the mean, which can be due either to the presence of a unit root or of a deterministic trend. In the former case of a unit root, stochastic shocks have permanent effects and the process is not meanreverting [...More...]  "Stationary Process" on: Wikipedia Yahoo 

J.R. Philip John Robert Philip AO FAA FRS (18 January 1927, Ballarat – 26 June 1999, Amsterdam) was an Australian soil physicist and hydrologist, internationally recognised for his contributions to the understanding of movement of water, energy and gases. While he never performed his own experimental work, he was recognised for his skills in mathematics that could be used to explain physical processes and solve real world problems.[1][2][3] His interests were not limited to Environmental mechanics and things mathematical, but included a keen interest in the arts. He was a published poet and a panellist on the Sulman Prize for Architecture. His poetry appears in anthologies edited by Judith Wright and in The Oxford Book of Australian Verse.[3]Contents1 Education and positions 2 Research 3 Achievements 4 Publications 5 References 6 External linksEducation and positions[edit] He was a recipient of a Scholarship for Scotch College, Melbourne, where he matriculated at age thirteen [...More...]  "J.R.
