Personal Equation
The term personal equation, in 19th- and early 20th-century science, referred to the idea that different observers have different reaction times, which can introduce bias when it comes to measurements and observations. Astronomy The term originated in astronomy, when it was discovered that numerous observers making simultaneous observations would record slightly different values (for example, in recording the exact time at which a star crossed the wires of a reticule in a telescope), some of which were of a significant enough difference to afford for problems in larger calculations. The existence of the effect was first discovered when, in 1796, the Astronomer Royal Neville Maskelyne dismissed his assistant Kinnebrooke because he could not better the error of his observations relative to Maskelyne's own values. The problem was forgotten and only analysed two decades later by Friedrich Wilhelm Bessel at Königsberg Observatory in Prussia. Setting up an experiment to compare t ...

Science
Science is a systematic discipline that builds and organises knowledge in the form of testable hypotheses and predictions about the universe. Modern science is typically divided into twoor threemajor branches: the natural sciences, which study the physical world, and the social sciences, which study individuals and societies. While referred to as the formal sciences, the study of logic, mathematics, and theoretical computer science are typically regarded as separate because they rely on deductive reasoning instead of the scientific method as their main methodology. Meanwhile, applied sciences are disciplines that use scientific knowledge for practical purposes, such as engineering and medicine. The history of science spans the majority of the historical record, with the earliest identifiable predecessors to modern science dating to the Bronze Age in Ancient Egypt, Egypt and Mesopotamia (). Their contributions to mathematics, astronomy, and medicine entered and shaped the Gree ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sleep
Sleep is a state of reduced mental and physical activity in which consciousness is altered and certain Sensory nervous system, sensory activity is inhibited. During sleep, there is a marked decrease in muscle activity and interactions with the surrounding environment. While sleep differs from wakefulness in terms of the ability to react to Stimulus (physiology), stimuli, it still involves active Human brain, brain patterns, making it more reactive than a coma or disorders of consciousness. Sleep occurs in sleep cycle, repeating periods, during which the body alternates between two distinct modes: rapid eye movement sleep (REM) and Non-rapid eye movement sleep, non-REM sleep. Although REM stands for "rapid eye movement", this mode of sleep has many other aspects, including virtual Rapid eye movement sleep#Muscle, paralysis of the body. Dreams are a succession of images, ideas, emotions, and sensations that usually occur involuntarily in the mind during certain stages of sleep. ...

Error
An error (from the Latin , meaning 'to wander'Oxford English Dictionary, s.v. “error (n.), Etymology,” September 2023, .) is an inaccurate or incorrect action, thought, or judgement. In statistics, "error" refers to the difference between the value which has been computed and the correct value. An error could result in failure or in a Deviation (statistics), deviation from the intended performance or behavior. Human behavior One reference differentiates between "error" and "mistake" as follows: In human behavior the norms or expectations for behavior or its consequences can be derived from the intention of the actor or from the expectations of other individuals or from a social grouping or from social norms. (See deviance (sociology), deviance.) Gaffes and faux pas can be labels for certain instances of this kind of error. More serious departures from social norms carry labels such as misbehavior and labels from the legal system, such as misdemeanor and crime. Departures f ...

History Of Astronomy
The history of astronomy focuses on the contributions civilizations have made to further their understanding of the universe beyond earth's atmosphere. Astronomy is one of the oldest natural sciences, achieving a high level of success in the second half of the first millennium. Astronomy has origins in the religious, mythological, cosmological, calendrical, and astrological beliefs and practices of prehistory. Early astronomical records date back to the Babylonians around 1000 BCE. There is also astronomical evidence of interest from early Chinese, Central American and North European cultures. Astronomy was used by early cultures for a variety of reasons. These include timekeeping, navigation, spiritual and religious practices, and agricultural planning. Ancient astronomers used their observations to chart the skies in an effort to learn about the workings of the universe. During the Renaissance Period, revolutionary ideas emerged about astronomy. One such idea was contributed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Theory‐ladenness Of Observations
In philosophy of science, an observation is said to be "theory-laden" when shaped by the investigator's theoretical presuppositions. The thesis is chiefly associated with the late 1950s–early 1960s work of Norwood Russell Hanson, Thomas Kuhn, and Paul Feyerabend, though it was likely first put forth some 50 years earlier, at least implicitly, by Pierre Duhem.Bogen, Jim (2014)"Theory and Observation in Science" In: Edward N. Zalta (ed.), ''The Stanford Encyclopedia of Philosophy'' (Summer 2014 Edition). Semantic theory-ladenness refers to the impact of theoretical assumptions on the meaning of observational terms, while perceptual theory-ladenness refers to their impact on the perceptual experience itself. Theory-ladenness is also relevant for measurement outcomes: the data thus acquired may be said to be theory-laden since it is meaningless by itself unless interpreted as the outcome of the measurement processes involved. Theory-ladenness poses a problem for the confirmation of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Source Criticism
Source criticism (or information evaluation) is the process of evaluating an information source, i.e.: a document, a person, a speech, a fingerprint, a photo, an observation, or anything used in order to obtain knowledge. In relation to a given purpose, a given information source may be more or less valid, reliable or relevant. Broadly, "source criticism" is the interdisciplinary study of how information sources are evaluated for given tasks. Meaning Problems in translation: The Danish word , like the Norwegian word and the Swedish word , derived from the German and is closely associated with the German historian Leopold von Ranke (1795–1886). Historian wrote: His anke'sfirst work ''Geschichte der romanischen und germanischen Völker von 1494–1514'' (History of the Latin and Teutonic Nations from 1494 to 1514) (1824) was a great success. It already showed some of the basic characteristics of his conception of Europe, and was of historiographical importance par ...

Infinite Regress
Infinite regress is a philosophical concept to describe a series of entities. Each entity in the series depends on its predecessor, following a recursive principle. For example, the epistemic regress is a series of beliefs in which the justification of each belief depends on the justification of the belief that comes before it. An infinite regress argument is an argument against a theory based on the fact that this theory leads to an infinite regress. For such an argument to be successful, it must demonstrate not just that the theory in question entails an infinite regress but also that this regress is ''vicious''. There are different ways in which a regress can be vicious. The most serious form of viciousness involves a contradiction in the form of ''metaphysical impossibility''. Other forms occur when the infinite regress is responsible for the theory in question being implausible or for its failure to solve the problem it was formulated to solve. Traditionally, it was of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Psychological Types
''Psychological Types'' () is a book by Carl Jung that was originally published in German by Rascher Verlag in 1921, and translated into English in 1923, becoming volume 6 of '' The Collected Works of C. G. Jung''. In the book, Jung proposes four main functions of consciousness: two perceiving or non-rational functions ( Sensation and Intuition), and two judging or rational functions ( Thinking and Feeling). These functions are modified by two main attitude types: extraversion and introversion. Jung proposes that the dominant function, along with the dominant attitude, characterizes consciousness, while its opposite is repressed and characterizes the unconscious. Based on this, the eight outstanding psychological types are: Extraverted sensation / Introverted sensation; Extraverted intuition / Introverted intuition; Extraverted thinking / Introverted thinking; and Extraverted feeling / Introverted feeling. Jung, as such, describes in detail the effects of tensions between t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carl Jung
Carl Gustav Jung ( ; ; 26 July 1875 – 6 June 1961) was a Swiss psychiatrist, psychotherapist, and psychologist who founded the school of analytical psychology. A prolific author of Carl Jung publications, over 20 books, illustrator, and correspondent, Jung was a complex and convoluted academic, best known for his concept of Jungian archetypes, archetypes. Alongside contemporaries Sigmund Freud, Freud and Alfred Adler, Adler, Jung became one of the most influential psychologists of the early 20th century and has fostered not only scholarship, but also popular interest.

William James
William James (January 11, 1842 – August 26, 1910) was an American philosopher and psychologist. The first educator to offer a psychology course in the United States, he is considered to be one of the leading thinkers of the late 19th century, one of the most influential philosophers and is often dubbed the "father of American psychology." Born into a wealthy family, James was the son of the Swedenborgian theologian Henry James Sr. and the brother of both the prominent novelist Henry James and the diarist Alice James. James trained as a physician and taught anatomy at Harvard, but never practiced medicine. Instead, he pursued his interests in psychology and then philosophy. He wrote widely on many topics, including epistemology, education, metaphysics, psychology, religion, and mysticism. Among his most influential books are '' The Principles of Psychology'', a groundbreaking text in the field of psychology; '' Essays in Radical Empiricism'', an important text in phil ...
