summary:
  A good example is the word laser, an acronym for "Light Amplification by Stimulated Emission of Radiation", and therefore all its letters should be capitalized. However, because of frequent use, this acronym became a neologism, i.e., it has integrated into English and most other languages. Consequently, laser is commonly written in small letters. It has even produced secondary acronyms such as LASIK (Laser-ASsisted in Situ Keratomileusis). A related acronym and neologism maser (Microwave Amplification by Stimulated Emission of Radiation) is much less known. Nevertheless, it is commonly written in small letters. On the contrary, acronym SPASER (Surface Plasmon Amplification by Stimulated Emission of Radiation) is capitalized. Many scientific acronyms or abbreviations reflect the artistic sense of their creators, e.g., AMANDA – Antarctic Muon And Neutrino Detector Array, a neutrino telescope BLAST – Balloon-borne Large Aperture Submillimeter Telescope COMICS – COoled Mid-Infrared Camera and Spectrometer FROG - Frequency-resolved optical gating MARVEL – Multi-object Apache Point Observatory Radial Velocity Exoplanet Large-area Survey, a NASA-funded project to search for exoplanets METATOY – METAmaTerial fOr raYs – a material that changes the direction of transmitted light rays PLANET – Probing Lensing Anomalies NETwork, a program to search for microlensing events SCREAM – Single Crystal

summary:
  Homogeneity and heterogeneity are concepts relating to the uniformity of a substance, process or image. A homogeneous feature is uniform in composition or character (i.e., color, shape, size, weight, height, distribution, texture, language, income, disease, temperature, radioactivity, architectural design, etc.); one that is heterogeneous is distinctly nonuniform in at least one of these qualities. == Etymology and spelling == The words homogeneous and heterogeneous come from Medieval Latin homogeneus and heterogeneus, from Ancient Greek ὁμογενής (homogenēs) and ἑτερογενής (heterogenēs), from ὁμός (homos, "same") and ἕτερος (heteros, "other, another, different") respectively, followed by γένος (genos, "kind"); -ous is an adjectival suffix. Alternate spellings omitting the last -e- (and the associated pronunciations) are common, but mistaken: homogenous is strictly a biological/pathological term which has largely been replaced by homologous. But use of homogenous to mean homogeneous has seen a rise since 2000, enough for it to now be considered an "established variant". Similarly, heterogenous is a spelling traditionally reserved to biology and pathology, referring to the property of an object in the body having its origin outside the body. == Scaling == The concepts are the same to every level of complexity. From atoms to galaxies, plants, animals, humans, and other living

summary:
  Organic describes forms, methods and patterns found in living systems such as the organisation of cells, to populations, communities, and ecosystems. Typically organic models stress the interdependence of the component parts, as well as their differentiation. Other properties of organic models include: the growth, life or development cycle the ability to adapt, learn, and evolve emergent behaviour or emergent properties steady change or growth, as opposed to instant change regulatory feedback composed of heterogeneous (diverse) parts Organic models are used especially in the design of artificial systems, and the description of social systems and constructs. == Uses == In the social sciences, the organic model has been drawn upon for ideas such as mechanical and organic solidarity and organic unity. Carl Ritter advanced the idea of Lebensraum using the metaphor of an organic, growing state. In computer science, organic networks grow in an ad hoc manner, while organic computing is autonomous and able to self-organise and heal. Bionics (biomimicry) is the engineering of technology through the use of systems found in biology. Organic architecture stresses interrelatedness as it combines the site, buildings, furnishings, and surroundings into a unified whole, each adapted to the others. Examples include the use of passive

summary:
  A phlegmatizer is a compound that minimizes the explosive tendency of another compound or material. The term is derived from the word phlegmatic, meaning 'not easily excited'. Many chemical compounds that are potentially explosive have useful non-explosive applications. One large family of phlegmatizers are phthalate esters, which are used as solvents to minimize the explosive tendency of organic peroxides, such as dibenzoyl peroxide and MEKP, which are widely used initiators for polymerizations. == See also == Phlegmatized explosive == References ==

summary:
  Photochemical action plots are a scientific tool used to understand the effects of different wavelengths of light on photochemical reactions. The methodology involves exposing a reaction solution to the same number of photons at varying monochromatic wavelengths, monitoring the conversion or reaction yield of starting materials and/or reaction products. Such global high-resolution analysis of wavelength-dependent chemical reactivity has revealed that maxima in absorbance and reactivity often do not align. Photochemical action plots are historically connected to (biological) action spectra. == Historical development == The study of biological responses to specific wavelengths dates back to the late 19th century. Research primarily focused on assessing photodamage from solar radiation using broad-band lamps and narrow filters. These studies quantified effects such as cell viability, production of erythema, vitamin D3 degradation, DNA changes, and skin cancer appearance. The first biological action spectrum was recorded by Engelmann, who used a prism to produce different colors of light and then illuminated cladophora in a bacteria suspension. He discovered the effects of different light wavelengths on photosynthesis, marking the first recorded action spectrum of photosynthesis. Critical evaluations of active wavelength regions in these studies helped identify contributing chromophores to processes such as photosynthesis. These chromophores are key

summary:
  A science magazine is a periodical publication with news, opinions, and reports about science, generally written for a non-expert audience. In contrast, a periodical publication, usually including primary research and/or reviews, that is written by scientific experts is called a "scientific journal". Science magazines are read by non-scientists and scientists who want accessible information on fields outside their specialization. Articles in science magazines are sometimes republished or summarized by the general press. == Examples of general science magazines == === Africa === === Asia === ==== Bangladesh ==== Byapon – Youth Science Magazine in Bengali Bigganchinta[1] BigganBarta (বিজ্ঞানবার্তা) – Free PDF Science Magazine in Bengali Bangachi (ব্যাঙাচি) – Free Science Magazine in Bengali published by Banger Chhater Biggan Biggan Ananda (বিজ্ঞান আনন্দ) - Published by Bangladesh Science Fiction Society (BSFS) Zero to Infinity (জিরো টু ইনফিনিটি) ==== India ==== Resonance, published by Indian Academy of Sciences Current Science Dream 2047, published by Vigyan Prasar Jnan o Bijnan, published by Bangiya Bijnan Parishad Sandarbh Science Reporter Safari ==== Japan ==== Newton press Nikkei Science ==== Kazakhstan ==== OYLA ==== Pakistan ==== Global Science ==== South Korea ==== Donga Science ==== Turkey ==== Bilim ve Teknik === Europe === EuroScientist ==== Austria

summary:
  Science and Technology in the Discovery of America (Spanish: La ciencia y la técnica en el descubrimiento de América), is a work by the historian and mathematician Julio Rey Pastor, published in Spanish in 1945, in Buenos Aires, by the Espasa-Calpe publishing. A second, "improved and corrected" edition was published in 1945. A third and fourth edition were published in 1951 and 1970, respectively. == Description == In this book, Rey Pastor analyzes the role of science and technology in the discovery of America, with special attention to the contributions of disciplines such as geography, cartography, nautical science and cosmography, which were decisive for the realization of transoceanic expeditions, such as that of Christopher Columbus, whom Rey Pastor considers a man of science, taking into account what was understood in his time by "man of science". The work reviews the scientific situation prior to the discovery and the evolution of latitude measurement and geographical representation techniques, highlighting how these innovations allowed the navigation challenges of the time to be faced. He insists on the enormous disproportion between the magnificent results of the discoverers and the poverty of the means at their disposal. The book highlights the leading role of Spanish

summary:
  "Sonnet to Science" (originally "Sonnet — To Science") is an 1829 poem by Edgar Allan Poe, published in Al Aaraaf, Tamerlane, and Minor Poems. == Summary == Poe asks why science preys on the poet. Science is peering, destructive and interested only in cold realities. It will not allow the poet to soar in fantasy or even to sit peacefully dreaming beneath a tree. == Publication history == In mid-November 1829, Poe agreed with the Baltimore firm Hatch and Dunning to publish his second volume of poetry, entitled Al Aaraaf, Tamerlane, and Minor Poems. This volume was the first instance in which Poe published his verse under his own name as opposed to his first publication, Tamerlane and Other Poems, which was only attributed to “a Bostonian”. A later published version of this poem includes the following note, “Private reasons—some of which have reference to the sin of plagiarism, and other to the date of Tennyson’s first poems—have induced me, after some hesitation, to re-publish these, the crude compositions of my earliest boyhood. They are printed verbatim—without alteration from the original edition—the date of which is too remote to be judiciously acknowledged.” == References == == External links == An
