System A system is a regularly interacting or interdependent group of items forming an integrated whole. Every system is delineated by its spatial and temporal boundaries, surrounded and influenced by its environment, described by its structure and purpose and expressed in its functioning. 

Coffeemaker
Coffeemakers or coffee machines are cooking appliances used to brew coffee. While there are many different types of coffeemakers using a number of different brewing principles, in the most common devices, coffee grounds are placed in a paper or metal filter inside a funnel, which is set over a glass or ceramic coffee pot, a cooking pot in the kettle family. Cold water is poured into a separate chamber, which is then heated up to the boiling point, and directed into the funnel [...More Info...] [...Related Items...] 

Latin
Latin (Latin: lingua latīna, IPA: [ˈlɪŋɡʷa laˈtiːna]) is a classical language belonging to the Italic branch of the IndoEuropean languages. The Latin alphabet is derived from the Etruscan and Greek alphabets, and ultimately from the Phoenician alphabet. Latin was originally spoken in Latium, in the Italian Peninsula. Through the power of the Roman Republic, it became the dominant language, initially in Italy and subsequently throughout the Roman Empire. Vulgar Latin developed into the Romance languages, such as Italian, Portuguese, Spanish, French, and Romanian. Latin, Greek and French have contributed many words to the English language. Latin and Ancient Greek roots are used in theology, biology, and medicine. By the late Roman Republic (75 BC), Old Latin had been standardised into Classical Latin [...More Info...] [...Related Items...] 

Greek Language
Greek (Modern Greek: ελληνικά, elliniká) is an independent branch of the IndoEuropean family of languages, native to Greece, Cyprus, Albania and other parts of the Eastern Mediterranean and the Black Sea. It has the longest documented history of any living IndoEuropean language, spanning at least 3,500 years of written records. Its writing system has been the Greek alphabet for the major part of its history; other systems, such as Linear B and the Cypriot syllabary, were used previously. The alphabet arose from the Phoenician script and was in turn the basis of the Latin, Cyrillic, Armenian, Coptic, Gothic, and many other writing systems. The Greek language holds an important place in the history of the Western world and Christianity; the canon of ancient Greek literature includes works in the Western canon such as the epic poems Iliad and Odyssey [...More Info...] [...Related Items...] 

Boundary (topology)
In topology and mathematics in general, the boundary of a subset S of a topological space X is the set of points which can be approached both from S and from the outside of S. More precisely, it is the set of points in the closure of S not belonging to the interior of S. An element of the boundary of S is called a boundary point of S. The term boundary operation refers to finding or taking the boundary of a set. Notations used for boundary of a set S include bd(S), fr(S), and ∂S. Some authors (for example Willard, in General Topology) use the term frontier instead of boundary in an attempt to avoid confusion with the concept of boundary used in algebraic topology and manifold theory [...More Info...] [...Related Items...] 

Nicolas Léonard Sadi Carnot
Nicolas Léonard Sadi Carnot (French: [kaʁno]; 1 June 1796 – 24 August 1832) was a French military engineer and physicist, often described as the "father of thermodynamics". Like Copernicus, he published only one book, the Reflections on the Motive Power of Fire (Paris, 1824), in which he expressed, at the age of 27 years, the first successful theory of the maximum efficiency of heat engines. In this work he laid the foundations of an entirely new discipline, thermodynamics [...More Info...] [...Related Items...] 

Geometry
Geometry (from the Ancient Greek: γεωμετρία; geo "earth", metron "measurement") is a branch of mathematics concerned with questions of shape, size, relative position of figures, and the properties of space. A mathematician who works in the field of geometry is called a geometer. Geometry arose independently in a number of early cultures as a practical way for dealing with lengths, areas, and volumes [...More Info...] [...Related Items...] 

Quantitative Research
In [Marketing] Quantitative research is aimed at producing data that can be analysed using statistics and the results expressed numerically. From marketing research perspective it is used to gather data from existing and potential customers. This might improve measuring market share, identifying spend per customer, establish market size, getting hard data on brand equity, testing usage and attitudes, testing variant of the marketing mix, and it can be used to create meaningful segmentation. In natural sciences and social sciences, quantitative research is the systematic empirical investigation of observable phenomena via statistical, mathematical or computational techniques. The objective of quantitative research is to develop and employ mathematical models, theories and hypotheses pertaining to phenomena [...More Info...] [...Related Items...] 

Mechanics
Mechanics (Greek μηχανική) is the area of physics concerned with the motions of macroscopic objects. Forces applied to objects result in displacements, or changes of an object's position relative to its environment. This branch of physics has its origins in Ancient Greece with the writings of Aristotle and Archimedes (see History of classical mechanics and Timeline of classical mechanics). During the early modern period, scientists such as Galileo, Kepler, and Newton laid the foundation for what is now known as classical mechanics. It is a branch of classical physics that deals with particles that are either at rest or are moving with velocities significantly less than the speed of light. It can also be defined as a branch of science which deals with the motion of and forces on bodies not in the quantum realm [...More Info...] [...Related Items...] 

Rudolf Clausius
Rudolf Julius Emanuel Clausius (2 January 1822 – 24 August 1888) was a German physicist and mathematician and is considered one of the central founders of the science of thermodynamics. By his restatement of Sadi Carnot's principle known as the Carnot cycle, he gave the theory of heat a truer and sounder basis. His most important paper, "On the Moving Force of Heat", published in 1850, first stated the basic ideas of the second law of thermodynamics. In 1865 he introduced the concept of entropy [...More Info...] [...Related Items...] 

Theorem
In mathematics, a theorem is a statement that has been proven on the basis of previously established statements, such as other theorems, and generally accepted statements, such as axioms. A theorem is a logical consequence of the axioms. The proof of a mathematical theorem is a logical argument for the theorem statement given in accord with the rules of a deductive system. The proof of a theorem is often interpreted as justification of the truth of the theorem statement. In light of the requirement that theorems be proved, the concept of a theorem is fundamentally deductive, in contrast to the notion of a scientific law, which is experimental. Many mathematical theorems are conditional statements. In this case, the proof deduces the conclusion from conditions called hypotheses or premises [...More Info...] [...Related Items...] 

Steam Engine
A steam engine is a heat engine that performs mechanical work using steam as its working fluid. The steam engine uses the force produced by steam pressure to push a piston back and forth inside a cylinder. This pushing force is transformed, by a connecting rod and flywheel, into rotational force for work. The term "steam engine" is generally applied only to reciprocating engines as just described, not to the steam turbine. Steam engines are external combustion engines, where the working fluid is separated from the combustion products [...More Info...] [...Related Items...]

Qualitative Research
Qualitative research is a scientific method of observation to gather nonnumerical data. This type of research "refers to the meanings, concepts, definitions, characteristics, metaphors, symbols, and description of things" and not to their "counts or measures". This research answers why and how a certain phenomenon may occur rather than how often. Qualitative research approaches are employed across many academic disciplines, focusing particularly on the human elements of the social and natural sciences; In less academic contexts, areas of application include qualitative market research, business, service demonstrations by nonprofits, and journalism. As a field of study, qualitative approaches include research concepts and methods from multiple established academic fields [...More Info...] [...Related Items...] 

Marshall McLuhan
Herbert Marshall McLuhan CC (July 21, 1911 – December 31, 1980) was a Canadian professor, philosopher, and public intellectual. His work is one of the cornerstones of the study of media theory. Born in Edmonton, Alberta, McLuhan studied at the University of Manitoba and the University of Cambridge. He began his teaching career as a professor of English at several universities in the U.S [...More Info...] [...Related Items...]
