Norman Robert Campbell
Norman Robert Campbell (1880–1949) was an English physicist and philosopher of science. Early life Norman Robert Campbell was born in 1880. He was the son of William Middleton Campbell, Governor of the Bank of England, and his wife Edith Agneta Bevan. He was educated at Eton College and at Trinity College, Cambridge, graduating B.A. in 1902. Career Campbell became a fellow at Trinity College, Cambridge in 1902. He was also a research assistant at the Cavendish Laboratory under the direction of J. J. Thomson. He became an honorary fellow in physics research at Leeds University in 1913. During World War I Campbell was at the National Physical Laboratory, working under Clifford Paterson. They investigated spark discharge in internal combustion engines. He then worked from 1919 to 1944 as a member of the research staff at the Hirst Research Centre of the General Electric Company England, set up in Wembley Middlesex in 1919. While at Hirst Research he encouraged unqua ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Physicist
A physicist is a scientist who specializes in the field of physics, which encompasses the interactions of matter and energy at all length and time scales in the physical universe. Physicists generally are interested in the root or ultimate causes of Phenomenon, phenomena, and usually frame their understanding in mathematical terms. They work across a wide range of Physics#Research fields, research fields, spanning all length scales: from atom, sub-atomic and particle physics, through biological physics, to physical cosmology, cosmological length scales encompassing the universe as a whole. The field generally includes two types of physicists: Experimental physics, experimental physicists who specialize in the observation of natural phenomena and the development and analysis of experiments, and Theoretical physics, theoretical physicists who specialize in mathematical modeling of physical systems to rationalize, explain and predict natural phenomena. Physicists can apply their k ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Workers' Educational Association
Workers' Educational Associations (WEA) are not-for-profit bodies that deliver further education to adults in the UK, Australia, New Zealand, and Canada. WEA UK WEA UK, founded in 1903, is the UK's largest voluntary sector provider of adult education and one of Britain's biggest charities. The WEA is a democratic and voluntary adult education movement. It delivers learning throughout England and Scotland. There was a related but independent WEA Cymru covering Wales, though it is now known as Adult Learning Wales since a merger in 2015 with YMCA Wales Community College. The WEA's provision is usually local to its students. In 2015–16 there were over 8,000 courses delivered in over 1,800 community venues and 75% of WEA students travelled less than 2 miles to their class. The WEA has throughout its history supported the development of similar educational initiatives and associations internationally. It is affiliated to the International Federation of Workers' Education Associati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Methuen Publishing
Methuen Publishing Ltd (; also known as Methuen Books) is an English publishing house. It was founded in 1889 by Sir Algernon Methuen (1856–1924) and began publishing in London in 1892. Initially, Methuen mainly published non-fiction academic works, eventually diversifying to encourage female authors and later translated works. E. V. Lucas headed the firm from 1924 to 1938. Establishment In June 1889, as a sideline to teaching, Algernon Methuen began to publish and market his own textbooks under the label Methuen & Co. The company's first success came in 1892 with the publication of Rudyard Kipling's '' Barrack-Room Ballads''. Rapid growth came with works by Marie Corelli, Hilaire Belloc, Robert Louis Stevenson, and Oscar Wilde ('' De Profundis'', 1905) as well as Edgar Rice Burroughs' ''Tarzan of the Apes''.Stevenson, page 59. In 1910, the business was converted into a limited liability company with E. V. Lucas and G.E. Webster joining the founder on the board of dire ...

Encyclopædia Britannica, Inc
An encyclopedia is a reference work or compendium providing summaries of knowledge, either general or special, in a particular field or discipline. Encyclopedias are divided into articles or entries that are arranged alphabetically by article name or by thematic categories, or else are hyperlinked and searchable. Encyclopedia entries are longer and more detailed than those in most dictionaries. Generally speaking, encyclopedia articles focus on ''factual information'' concerning the subject named in the article's title; this is unlike dictionary entries, which focus on linguistic information about words, such as their etymology, meaning, pronunciation, use, and grammatical forms.Béjoint, Henri (2000)''Modern Lexicography'', pp. 30–31. Oxford University Press. Encyclopedias have existed for around 2,000 years and have evolved considerably during that time as regards language (written in a major international or a vernacular language), size (few or many volumes), intent ...

Campbell's Theorem (probability)
In probability theory and statistics, Campbell's theorem or the Campbell–Hardy theorem is either a particular equation or set of results relating to the Expected value, expectation of a Function (mathematics), function summed over a point process to an integral involving the Moment measure#First moment measure, mean measure of the point process, which allows for the calculation of expected value and variance of the random summation, sum. One version of the theorem,D. Stoyan, W. S. Kendall, J. Mecke. ''Stochastic geometry and its applications'', volume 2. Wiley Chichester, 1995. also known as Campbell's formula, entails an integral equation for the aforementioned sum over a general point process, and not necessarily a Poisson point process. There also exist equations involving moment measures and factorial moment measures that are considered versions of Campbell's formula. All these results are employed in probability and statistics with a particular importance in the theory of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scientific Method
The scientific method is an Empirical evidence, empirical method for acquiring knowledge that has been referred to while doing science since at least the 17th century. Historically, it was developed through the centuries from the ancient and medieval world. The scientific method involves careful observation coupled with rigorous skepticism, because Philosophy of science#Observation inseparable from theory, cognitive assumptions can distort the interpretation of the Perception#Process and terminology, observation. Scientific inquiry includes creating a testable hypothesis through inductive reasoning, testing it through experiments and statistical analysis, and adjusting or discarding the hypothesis based on the results. Although procedures vary across Branches of science, fields, the underlying #Process, process is often similar. In more detail: the scientific method involves making conjectures (hypothetical explanations), predicting the logical consequences of hypothesis, then ...

Experience
Experience refers to Consciousness, conscious events in general, more specifically to perceptions, or to the practical knowledge and familiarity that is produced by these processes. Understood as a conscious event in the widest sense, experience involves a subject to which various items are presented. In this sense, seeing a yellow bird on a branch presents the subject with the objects "bird" and "branch", the relation between them and the property "yellow". Unreal items may be included as well, which happens when experiencing hallucinations or dreams. When understood in a more restricted sense, only sensory consciousness counts as experience. In this sense, experience is usually identified with perception and contrasted with other types of conscious events, like thinking or Imagination, imagining. In a slightly different sense, experience refers not to the conscious events themselves but to the practical knowledge and familiarity they produce. Hence, it is important that direct per ...

Observation
Observation in the natural sciences is an act or instance of noticing or perceiving and the acquisition of information from a primary source. In living beings, observation employs the senses. In science, observation can also involve the perception and recording of data via the use of scientific instruments. The term may also refer to any data collected during the scientific activity. Observations can be qualitative, that is, the absence or presence of a property is noted and the observed phenomenon described, or quantitative if a numerical value is attached to the observed phenomenon by counting or measuring. Science The scientific method requires observations of natural phenomena to formulate and test hypotheses. It consists of the following steps: # Ask a question about a phenomenon # Make observations of the phenomenon # Formulate a hypothesis that tentatively answers the question # Predict logical, observable consequences of the hypothesis that have not yet been inv ...

Hypothesis
A hypothesis (: hypotheses) is a proposed explanation for a phenomenon. A scientific hypothesis must be based on observations and make a testable and reproducible prediction about reality, in a process beginning with an educated guess or thought. If a hypothesis is repeatedly independently demonstrated by experiment to be true, it becomes a scientific theory. In colloquial usage, the words "hypothesis" and "theory" are often used interchangeably, but this is incorrect in the context of science. A working hypothesis is a provisionally-accepted hypothesis used for the purpose of pursuing further progress in research. Working hypotheses are frequently discarded, and often proposed with knowledge (and warning) that they are incomplete and thus false, with the intent of moving research in at least somewhat the right direction, especially when scientists are stuck on an issue and brainstorming ideas. A different meaning of the term ''hypothesis'' is used in formal l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Theory
A theory is a systematic and rational form of abstract thinking about a phenomenon, or the conclusions derived from such thinking. It involves contemplative and logical reasoning, often supported by processes such as observation, experimentation, and research. Theories can be scientific, falling within the realm of empirical and testable knowledge, or they may belong to non-scientific disciplines, such as philosophy, art, or sociology. In some cases, theories may exist independently of any formal discipline. In modern science, the term "theory" refers to Scientific theory, scientific theories, a well-confirmed type of explanation of nature, made in a way Consistency, consistent with the scientific method, and fulfilling the Scientific theory#Characteristics of theories, criteria required by modern science. Such theories are described in such a way that scientific tests should be able to provide Empirical evidence, empirical support for it, or Empirical evidence, empirical contradi ...

Michael Faraday
Michael Faraday (; 22 September 1791 – 25 August 1867) was an English chemist and physicist who contributed to the study of electrochemistry and electromagnetism. His main discoveries include the principles underlying electromagnetic induction, diamagnetism, and electrolysis. Although Faraday received little formal education, as a self-made man, he was one of the most influential scientists in history. It was by his research on the magnetic field around a Electrical conductor, conductor carrying a direct current that Faraday established the concept of the electromagnetic field in physics. Faraday also established that magnetism could Faraday effect, affect rays of light and that there was an underlying relationship between the two phenomena. the 1911 ''Encyclopædia Britannica''. He similarly discovered the principles of electromagnetic induction, diamagnetism, and the Faraday's laws of electrolysis, laws of electrolysis. His inventions of electric motor, electromagnetic rotar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
