Observation
Observation is the active 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, only the absence or presence of a property is noted, 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 natural 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 investigated # Test the hypothesis' predictions by an experiment, observational study, field study, or ...

Sunday Observer (Sri Lanka)
''Sunday Observer'' is a weekly English-language newspaper in Sri Lanka, published on Sundays. The ''Sunday Observer'' and its sister newspapers the '' Daily News'', ''Dinamina'', ''Silumina'' and ''Thinakaran'' are published by Associated Newspapers of Ceylon Limited (Lake House), a government-owned corporation. The paper, which was established in the present-day format in 1928, has roots that date back to 1834 when Sri Lanka was under the British rule. It is the oldest Sri Lankan newspaper in circulation apart from the ''Government Gazette''. The current Editor is Dharisha Bastians. History Origins The British captured the coastal areas of Sri Lanka in 1796 and had consolidated their power throughout the island by 1818. In 1829 the Colonial Office appointed the Colebrooke-Cameron Commission to evaluate the administration of the country under the Governor of Ceylon, Edward Barnes, and to recommend reforms. The commission's recommendations, presented in 1833, marked the begi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Donald Alaster Macdonald
Donald Alaster Macdonald (6 June 1859 – 23 November 1932) was an Australian journalist and nature writer, writing under the pen names including 'Observer' and 'Gnuyang' (gossip).Hugh Anderson,Macdonald, Donald Alaster (1859–1932), ''Australian Dictionary of Biography'', Vol. 10, Melbourne University Press, 1986, p. 249. Retrieved 14 November 2010 He was considered one of Australia's widely known journalists, and is in the Melbourne Press Club's Australian Media Hall of Fame. He was credited with making 'Australian natural history and botany popular interests'. Early life Macdonald was born in Fitzroy, Victoria, a suburb of Melbourne, the elder son of Donald Macdonald (of Scottish–Canadian heritage) and his wife Margaret, ''née'' Harris. Macdonald was educated at the Keilor state school where he became a pupil-teacher in 1876. He later joined ''The Corowa Free Press'' and then the ''Melbourne Argus'' newspaper in 1881.

Enneagram Of Personality
The Enneagram of Personality, or simply the Enneagram (from the Greek words [, meaning "nine"] and [, meaning something "written" or "drawn"]), is a model of the Psyche (psychology), human psyche which is principally understood and taught as a Psychological typologies, typology of nine interconnected personality types. Although the origins and history of many of the ideas and theories associated with the Enneagram of Personality are a matter of dispute, contemporary Enneagram theories are principally derived from the teachings of the Bolivian psycho-spiritual teacher Oscar Ichazo from the 1950s and the Chilean psychiatrist Claudio Naranjo from the 1970s. Naranjo's theories were also influenced by some earlier teachings about personality by George Gurdjieff and the Fourth Way tradition. As a typology, the Enneagram defines nine personality types (sometimes called "enneatypes"), which are represented by the points of a geometric figure called an ''Enneagram (geometry), enneagr ...

Ultimate (sport)
Ultimate, originally known as ultimate Frisbee, is a non-contact team sport played with a frisbee flung by hand. Ultimate was developed in 1968 by AJ Gator in Maplewood, New Jersey. Although ultimate resembles many traditional sports in its athletic requirements, it is unlike most sports due to its focus on self-officiating, even at the highest levels of competition. The term Frisbee, often used to generically describe all flying discs, is a registered trademark of the Wham-O toy company, and thus the sport is not formally called "ultimate Frisbee", though this name is still in common casual use. Points are scored by passing the disc to a teammate in the opposing end zone. Other basic rules are that players must not take steps while holding the disc, and interceptions, incomplete passes, and passes out of bounds are turnovers. Rain, wind, or occasionally other adversities can make for a testing match with rapid turnovers, heightening the pressure of play. From its beginnings i ...

Election Monitoring
Election monitoring involves the observation of an election by one or more independent parties, typically from another country or from a non-governmental organization (NGO). The monitoring parties aim primarily to assess the conduct of an election process on the basis of national legislation and of international election standards. There are national and international election observers. Monitors do not directly prevent electoral fraud, but rather record and report instances of suspicious practices. Election observation increasingly looks at the entire electoral process over a long period of time, rather than at election-day proceedings only. The legitimacy of an election can be affected by the criticism of monitors, unless they are themselves seen as biased. A notable individual is often appointed honorary leader of a monitoring organization in an effort to enhance legitimacy of the monitoring process. History The first monitored election was that of an 1857 plebiscite in Mold ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Observer Status
Observer status is a privilege granted by some organizations to non-members to give them an ability to participate in the organization's activities. Observer status is often granted by intergovernmental organizations (IGO) to non-member parties and international nongovernmental organizations (INGO) that have an interest in the IGO's activities. Observers generally have a limited ability to participate in the IGO, lacking the ability to vote or propose resolutions. United Nations United Nations General Assembly The United Nations General Assembly may grant entities observer status. The United Nations welcomes many international agencies, entities, and two non-member states as observers, State of Palestine and Vatican City. Observers have the right to speak at United Nations General Assembly meetings, but not to vote on resolutions. Non-member observer states are recognized as sovereign states, and are free to submit a petition to join as a full member at their discretion. At prese ...

Observational Astronomy
Observational astronomy is a division of astronomy that is concerned with recording data about the observable universe, in contrast with theoretical astronomy, which is mainly concerned with calculating the measurable implications of physical models. It is the practice and study of observation, observing celestial objects with the use of telescopes and other astronomical instruments. As a space science, science, the study of astronomy is somewhat hindered in that direct experiments with the properties of the distant universe are not possible. However, this is partly compensated by the fact that astronomers have a vast number of visible examples of stellar phenomena that can be examined. This allows for observational data to be plotted on graphs, and general trends recorded. Nearby examples of specific phenomena, such as variable stars, can then be used to infer the behavior of more distant representatives. Those distant yardsticks can then be employed to measure other phenomena ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Observer (special Relativity)
In special relativity, an observer is a frame of reference from which a set of objects or events are being measured. Usually this is an inertial reference frame or "inertial observer". Less often an observer may be an arbitrary non-inertial reference frame such as a Rindler frame which may be called an "accelerating observer". The special relativity usage differs significantly from the ordinary English meaning of "observer". Reference frames are inherently nonlocal constructs, covering all of space and time or a nontrivial part of it; thus it does not make sense to speak of an observer (in the special relativistic sense) having a location. Also, an inertial observer cannot accelerate at a later time, nor can an accelerating observer stop accelerating. Physicists use the term "observer" as shorthand for a specific reference frame from which a set of objects or events is being measured. Speaking of an observer in special relativity is not specifically hypothesizing an individual ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Observer (quantum Physics)
Some interpretations of quantum mechanics posit a central role for an observer of a quantum phenomenon. The quantum mechanical observer is tied to the issue of observer effect, where a measurement necessarily requires interacting with the physical object being measured, affecting its properties through the interaction. The term "observable" has gained a technical meaning, denoting a Hermitian operator that represents a measurement. The prominence of seemingly subjective or anthropocentric ideas like "observer" in the early development of the theory has been a continuing source of disquiet and philosophical dispute. A number of new-age religious or philosophical views give the observer a more special role, or place constraints on who or what can be an observer. There is no credible peer-reviewed research that backs such claims. As an example of such claims, Fritjof Capra declared, "The crucial feature of atomic physics is that the human observer is not only necessary to observe the p ...

Observer (physics)
General relativity, also known as the general theory of relativity and Einstein's theory of gravity, is the differential geometry, geometric scientific theory, theory of gravitation published by Albert Einstein in 1915 and is the current description of gravitation in modern physics. General theory of relativity, relativity generalizes special relativity and refines Newton's law of universal gravitation, providing a unified description of gravity as a geometric property of space and time in physics, time or four-dimensional space, four-dimensional spacetime. In particular, the ' is directly related to the energy and momentum of whatever matter and radiation are present. The relation is specified by the Einstein field equations, a system of second order partial differential equations. Newton's law of universal gravitation, which describes classical gravity, can be seen as a prediction of general relativity for the almost flat spacetime geometry around stationary mass distribution ...

Observer (meteorological)
A meteorological observer, or weather observer, is a person authorized by a weather authority to make or record meteorological observations. They are technicians who are responsible for the accurate observation, rapid measurement, timely collection, recording, and timely submission of meteorological parameters and information and various atmospheric phenomena to the Meteorological Center. Surface, upper air, radar, and satellite are all forms of weather observations. Role Meteorological observers play a key role in many flood, drought, environmental and water resources applications. Whilst rainfall observations are most widely used, other parameters of interest include air temperatures, humidity and wind speeds. The main measurement techniques include raingauges, weather stations and weather radar, with satellite precipitation estimates playing an important role in data-sparse regions. METARs are generated by both government-owned and privately contracted facilities. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
