Lumpers And Splitters
Lumpers and splitters are opposing factions in any academic discipline that has to place individual examples into rigorously defined categories. The lumper–splitter problem occurs when there is the desire to create classifications and assign examples to them, for example, schools of literature, biological taxa, and so on. A "lumper" is a person who assigns examples broadly, judging that differences are not as important as signature similarities. A "splitter" makes precise definitions, and creates new categories to classify samples that differ in key ways. Origin of the terms The earliest known use of these terms was thought to be Charles Darwin, in a letter to Joseph Dalton Hooker in 1857: "It is good to have hair-splitters & lumpers". But according to research done by the deputy director at NCSE, Glenn Branch, the credit is due to naturalist Edward Newman who wrote in 1845, "The time has arrived for discarding imaginary species, and the duty of doing this is as imperative ...

Academic Discipline
An academic discipline or academic field is a subdivision of knowledge that is taught and researched at the college or university level. Disciplines are defined (in part) and recognized by the academic journals in which research is published, and the learned society, learned societies and academic departments or faculties within colleges and universities to which their practitioners belong. Academic disciplines are conventionally divided into the humanities (including philosophy, Linguistics, language, art and cultural studies), the scientific disciplines (such as physics, chemistry, and biology); and the formal sciences like mathematics and computer science. The social sciences are sometimes considered a fourth category. It is also known as a ''field of study'', ''field of inquiry'', ''research field'' and ''branch of knowledge''. The different terms are used in different countries and fields. Individuals associated with academic disciplines are commonly referred to as ''expert ...

Evolution
Evolution is the change in the heritable Phenotypic trait, characteristics of biological populations over successive generations. It occurs when evolutionary processes such as natural selection and genetic drift act on genetic variation, resulting in certain characteristics becoming more or less common within a population over successive generations. The process of evolution has given rise to biodiversity at every level of biological organisation. The scientific theory of evolution by natural selection was conceived independently by two British naturalists, Charles Darwin and Alfred Russel Wallace, in the mid-19th century as an explanation for why organisms are adapted to their physical and biological environments. The theory was first set out in detail in Darwin's book ''On the Origin of Species''. Evolution by natural selection is established by observable facts about living organisms: (1) more offspring are often produced than can possibly survive; (2) phenotypic variatio ...

Software Engineering
Software engineering is a branch of both computer science and engineering focused on designing, developing, testing, and maintaining Application software, software applications. It involves applying engineering design process, engineering principles and computer programming expertise to develop software systems that meet user needs. The terms ''programmer'' and ''coder'' overlap ''software engineer'', but they imply only the construction aspect of a typical software engineer workload. A software engineer applies a software development process, which involves defining, Implementation, implementing, Software testing, testing, Project management, managing, and Software maintenance, maintaining software systems, as well as developing the software development process itself. History Beginning in the 1960s, software engineering was recognized as a separate field of engineering. The development of software engineering was seen as a struggle. Problems included software that was over ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sergei Rachmaninoff
Sergei Vasilyevich Rachmaninoff; in Russian pre-revolutionary script. (28 March 1943) was a Russian composer, virtuoso pianist, and Conducting, conductor. Rachmaninoff is widely considered one of the finest pianists of his day and, as a composer, one of the last great representatives of Romantic music, Romanticism in Russian classical music. Early influences of Pyotr Ilyich Tchaikovsky, Tchaikovsky, Nikolai Rimsky-Korsakov, Rimsky-Korsakov, and other Russian composers gave way to a thoroughly personal idiom notable for its song-like melody, melodicism, Music#Expression, expressiveness, dense Counterpoint, contrapuntal textures, and rich Orchestration, orchestral colours. The piano is featured prominently in Rachmaninoff's compositional output and he used his skills as a performer to fully explore the expressive and technical possibilities of the instrument. Born into a musical family, Rachmaninoff began learning the piano at the age of four. He studied piano and composition at ...

Johann Nepomuk Hummel
Johann Nepomuk Hummel (14 November 177817 October 1837) was an Austrian composer and pianist. His music reflects the transition from the Classical to the Romantic musical era. He was a pupil of Wolfgang Amadeus Mozart, Antonio Salieri, and Joseph Haydn. Hummel significantly influenced later piano music of the nineteenth century, particularly in the works of Frédéric Chopin, Franz Liszt, and Felix Mendelssohn. Life Early life Hummel was born in Pressburg, Kingdom of Hungary (now Bratislava, Slovakia). Unusually for that period, he was an only child. He was named after the Czech patron saint John of Nepomuk. His father, Johannes Hummel, was the director of the Imperial School of Military Music in Vienna; his mother, Margarethe Sommer Hummel, was the widow of the wigmaker Josef Ludwig. The couple married just four months before his birth. Hummel was a child prodigy. At the age of eight, he was offered music lessons by the classical composer Wolfgang Amadeus Mozart, wh ...

Romanticism
Romanticism (also known as the Romantic movement or Romantic era) was an artistic and intellectual movement that originated in Europe towards the end of the 18th century. The purpose of the movement was to advocate for the importance of subjectivity and objectivity (philosophy), subjectivity, imagination, and appreciation of nature in society and culture in response to the Age of Enlightenment and the Industrial Revolution. Romanticists rejected the social conventions of the time in favour of a moral outlook known as individualism. They argued that passion (emotion), passion and intuition were crucial to understanding the world, and that beauty is more than merely an classicism, affair of form, but rather something that evokes a strong emotional response. With this philosophical foundation, the Romanticists elevated several key themes to which they were deeply committed: a Reverence (emotion), reverence for nature and the supernatural, nostalgia, an idealization of the past as ...

Distinction Without A Difference
A distinction without a difference is a type of logical fallacy where an author or speaker attempts to describe a distinction between two things where no discernible difference exists. It is particularly used when a word or phrase has connotations associated with it that one party to an argument prefers to avoid. For example, a person might say "I did not lie; I merely stretched the truth a little bit." Form of the fallacy * Claim X is made where the truth of the claim requires a distinct difference between A and B. * There is no distinct difference between A and B. * Therefore, claim X is incorrectly claimed to be true. Example In the following conversation: * Sergio: There is no way I would ever even consider taking dancing lessons. * Kitty: How about I ask my friend from work to teach you? * Sergio: If you know someone who is willing to teach me how to dance, then I am willing to learn, sure. Sergio's fallacy is thinking that being taught by someone is different than taking ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (). The term angiosperm is derived from the Ancient Greek, Greek words (; 'container, vessel') and (; 'seed'), meaning that the seeds are enclosed within a fruit. The group was formerly called Magnoliophyta. Angiosperms are by far the most diverse group of Embryophyte, land plants with 64 Order (biology), orders, 416 Family (biology), families, approximately 13,000 known Genus, genera and 300,000 known species. They include all forbs (flowering plants without a woody Plant stem, stem), grasses and grass-like plants, a vast majority of broad-leaved trees, shrubs and vines, and most aquatic plants. Angiosperms are distinguished from the other major seed plant clade, the gymnosperms, by having flowers, xylem consisting of vessel elements instead of tracheids, endosperm within their seeds, and fruits that completely envelop the seeds. The ancestors of flowering plants diverged from the commo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fern
The ferns (Polypodiopsida or Polypodiophyta) are a group of vascular plants (plants with xylem and phloem) that reproduce via spores and have neither seeds nor flowers. They differ from mosses by being vascular, i.e., having specialized tissues that conduct water and nutrients, and in having life cycles in which the branched sporophyte is the dominant phase. Ferns have complex leaf, leaves called megaphylls that are more complex than the microphylls of clubmosses. Most ferns are leptosporangiate ferns. They produce coiled Fiddlehead fern, fiddleheads that uncoil and expand into fronds. The group includes about 10,560 known extant species. Ferns are defined here in the broad sense, being all of the Polypodiopsida, comprising both the leptosporangiate (Polypodiidae (plant), Polypodiidae) and eusporangiate ferns, the latter group including horsetails, Psilotaceae, whisk ferns, marattioid ferns, and ophioglossoid ferns. The fern crown group, consisting of the leptosporangiates and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lycophyte
The lycophytes, when broadly circumscribed, are a group of vascular plants that include the clubmosses. They are sometimes placed in a division Lycopodiophyta or Lycophyta or in a subdivision Lycopodiophytina. They are one of the oldest lineages of extant (living) vascular plants; the group contains extinct plants that have been dated from the Silurian (ca. 425 million years ago). Lycophytes were some of the dominating plant species of the Carboniferous period, and included the tree-like Lepidodendrales, some of which grew over in height, although extant lycophytes are relatively small plants. The scientific names and the informal English names used for this group of plants are ambiguous. For example, "Lycopodiophyta" and the shorter "Lycophyta" as well as the informal "lycophyte" may be used to include the extinct zosterophylls or to exclude them. Description Lycophytes reproduce by spores and have alternation of generations in which (like other vascular plants) the sporop ...
