Electronic musical instrumentAn electronic musical instrument or electrophone is a musical instrument that produces sound using electronic circuitry. Such an instrument sounds by outputting an electrical, electronic or digital audio signal that ultimately is plugged into a power amplifier which drives a loudspeaker, creating the sound heard by the performer and listener. An electronic instrument might include a user interface for controlling its sound, often by adjusting the pitch, frequency, or duration of each note.
Mechanism (biology)In the science of biology, a mechanism is a system of causally interacting parts and processes that produce one or more effects. Scientists explain phenomena by describing mechanisms that could produce the phenomena. For example, natural selection is a mechanism of biological evolution; other mechanisms of evolution include genetic drift, mutation, and gene flow. In ecology, mechanisms such as predation and host-parasite interactions produce change in ecological systems.
Feminist artFeminist art is a category of art associated with the late 1960s and 1970s feminist movement. Feminist art highlights the societal and political differences women experience in their lives. The hopeful gain from this form of art is to bring a positive and understanding change to the world, in hope to lead to equality or liberation. Media used range from traditional art forms such as painting to more unorthodox methods such as performance art, conceptual art, body art, craftivism, video, film, and fiber art.
AvatarAvatar (अवतार, ; ɐʋɐt̪aːɾɐ) is a concept within Hinduism that in Sanskrit literally means "descent". It signifies the material appearance or incarnation of a powerful deity, or spirit on Earth. The relative verb to "alight, to make one's appearance" is sometimes used to refer to any guru or revered human being. The word avatar does not appear in the Vedic literature; however, it appears in developed forms in post-Vedic literature, and as a noun particularly in the Puranic literature after the 6th century CE.
EtiologyEtiology (ˌiːtiˈɒlədʒi; alternatively spelled aetiology or ætiology) is the study of causation or origination. The word is derived from the Greek word (), meaning "giving a reason for" (). More completely, etiology is the study of the causes, origins, or reasons behind the way that things are, or the way they function, or it can refer to the causes themselves. The word is commonly used in medicine (pertaining to causes of disease) and in philosophy, but also in physics, biology, psychology, government, geography, spatial analysis and theology in reference to the causes or origins of various phenomena.
PrincipleA principle is a fundamental truth or proposition that serves as the foundation for a system of beliefs or behavior or a chain of reasoning.That is a guide for behavior or evaluation. In law, it is a rule that has to be or usually is to be followed. It can be desirably followed, or it can be an inevitable consequence of something, such as the laws observed in nature or the way that a system is constructed.
Tertiary sourceA tertiary source is an index or textual consolidation of already published primary and secondary sources that does not provide additional interpretations or analysis of the sources. Some tertiary sources can be used as an aid to find key (seminal) sources, key terms, general common knowledge and established mainstream science on a topic. The exact definition of tertiary varies by academic field. Academic research standards generally do not accept tertiary sources such as encyclopedias as citations, although survey articles are frequently cited rather than the original publication.
Expert witnessAn expert witness, particularly in common law countries such as the United Kingdom, Australia, and the United States, is a person whose opinion by virtue of education, training, certification, skills or experience, is accepted by the judge as an expert. The judge may consider the witness's specialized (scientific, technical or other) opinion about evidence or about facts before the court within the expert's area of expertise, to be referred to as an "expert opinion".
FiduciaryA fiduciary is a person who holds a legal or ethical relationship of trust with one or more other parties (person or group of persons). Typically, a fiduciary prudently takes care of money or other assets for another person. One party, for example, a corporate trust company or the trust department of a bank, acts in a fiduciary capacity to another party, who, for example, has entrusted funds to the fiduciary for safekeeping or investment.
ErasmusDesiderius Erasmus Roterodamus (ˌdɛzɪˈdɪəriəs_ɪˈræzməs; ˌdeːziˈdeːriʏs eˈrɑsmʏs; English: Erasmus of Rotterdam or Erasmus; 28 October 1466 – 12 July 1536) was a Dutch Christian humanist, Catholic theologian, educationalist, satirist and philosopher. Through his vast number of translations, books, essays and letters, he is considered one of the most influential thinkers of the Northern Renaissance and one of the major figures of Dutch and Western culture.
EmpireAn empire is a political unit made up of several territories and peoples, "usually created by conquest, and divided between a dominant center and subordinate peripheries". The center of the empire (sometimes referred to as the metropole) exercises political control over the peripheries. Within an empire, different populations have different sets of rights and are governed differently.
Logic puzzleA logic puzzle is a puzzle deriving from the mathematical field of deduction. The logic puzzle was first produced by Charles Lutwidge Dodgson, who is better known under his pen name Lewis Carroll, the author of Alice's Adventures in Wonderland. In his book The Game of Logic he introduced a game to solve problems such as confirming the conclusion "Some greyhounds are not fat" from the statements "No fat creatures run well" and "Some greyhounds run well".
EmpiricismIn philosophy, empiricism is an epistemological view that holds that true knowledge or justification comes only or primarily from sensory experience. It is one of several competing views within epistemology, along with rationalism and skepticism. Empiricism emphasizes the central role of empirical evidence in the formation of ideas, rather than innate ideas or traditions. However, empiricists may argue that traditions (or customs) arise due to relations of previous sensory experiences.
Experimental cancer treatmentExperimental cancer treatments are mainstream medical therapies intended to treat cancer by improving on, supplementing or replacing conventional methods (surgery, chemotherapy, radiation, and immunotherapy). However, researchers are still trying to determine whether these treatments are safe and effective treatments. Experimental cancer treatments are normally available only to people who participate in formal research programs, which are called clinical trials.
Moral agencyMoral agency is an individual's ability to make moral choices based on some notion of right and wrong and to be held accountable for these actions. A moral agent is "a being who is capable of acting with reference to right and wrong." Most philosophers suggest only rational beings, who can reason and form self-interested judgments, are capable of being moral agents. Some suggest those with limited rationality (for example, people who are mildly mentally disabled or infants) also have some basic moral capabilities.
EdoEdo (), also romanized as Jedo, Yedo or Yeddo, is the former name of Tokyo. Edo, formerly a jōkamachi (castle town) centered on Edo Castle located in Musashi Province, became the de facto capital of Japan from 1603 as the seat of the Tokugawa shogunate. Edo grew to become one of the largest cities in the world under the Tokugawa. After the Meiji Restoration in 1868 the Meiji government renamed Edo as Tokyo (, "Eastern Capital") and relocated the Emperor from the historic capital of Kyoto to the city.
Graphic novelA graphic novel is a long-form, fictional work of sequential art. The term graphic novel is often applied broadly, including fiction, non-fiction, and anthologized work, though this practice is highly contested by comics scholars and industry professionals. It is, at least in the United States, typically distinct from the term comic book, which is generally used for comics periodicals and trade paperbacks (see American comic book). Fan historian Richard Kyle coined the term graphic novel in an essay in the November 1964 issue of the comics fanzine Capa-Alpha.
ExpressionismExpressionism is a modernist movement, initially in poetry and painting, originating in Northern Europe around the beginning of the 20th century. Its typical trait is to present the world solely from a subjective perspective, distorting it radically for emotional effect in order to evoke moods or ideas. Expressionist artists have sought to express the meaning of emotional experience rather than physical reality. Expressionism developed as an avant-garde style before the First World War.
Aristotelian physicsAristotelian physics is the form of natural science or natural philosophy described in the works of the Greek philosopher Aristotle (384–322 BC). In his work Physics, Aristotle intended to establish general principles of change that govern all natural bodies, both living and inanimate, celestial and terrestrial including all motion (change with respect to place), quantitative change (change with respect to size or number), qualitative change, and substantial change ("coming to be" [coming into existence, 'generation'] or "passing away" [no longer existing, 'corruption']).
Urban revolutionIn anthropology and archaeology, the urban revolution is the process by which small, kin-based, illiterate agricultural villages were transformed into large, socially complex, urban societies. Australian archaeologist V. Gordon Childe introduced the term "urban revolution" in the 1930s. Childe also coined the term "Neolithic Revolution" to describe the earlier process by which hunter-gatherer societies domesticated crops and animals and began a farming lifestyle.
