The Structure of Scientific RevolutionsThe Structure of Scientific Revolutions is a book about the history of science by philosopher Thomas S. Kuhn. Its publication was a landmark event in the history, philosophy, and sociology of science. Kuhn challenged the then prevailing view of progress in science in which scientific progress was viewed as "development-by-accumulation" of accepted facts and theories. Kuhn argued for an episodic model in which periods of conceptual continuity where there is cumulative progress, which Kuhn referred to as periods of "normal science", were interrupted by periods of revolutionary science.
Timber framingTimber framing (Holzfachwerk) and "post-and-beam" construction are traditional methods of building with heavy timbers, creating structures using squared-off and carefully fitted and joined timbers with joints secured by large wooden pegs. If the structural frame of load-bearing timber is left exposed on the exterior of the building it may be referred to as half-timbered, and in many cases the infill between timbers will be used for decorative effect.
Framing (construction)Framing, in construction, is the fitting together of pieces to give a structure support and shape. Framing materials are usually wood, engineered wood, or structural steel. The alternative to framed construction is generally called mass wall construction, where horizontal layers of stacked materials such as log building, masonry, rammed earth, adobe, etc. are used without framing.
Proposal (business)A business proposal is a written offer from a seller to a prospective sponsor. Business proposals are often a key step in the complex sales process—i.e., whenever a buyer considers more than price in a purchase. When one person signifies to another their willingness to do or to abstain from doing anything with a view to obtaining the assent of the other to such act or abstinence, they are said to make a proposal. A proposal puts the buyer's requirements in a context that favors the seller's products and services, and educates the buyer about the seller's capability to satisfy their needs.
Building codeA building code (also building control or building regulations) is a set of rules that specify the standards for constructed objects such as buildings and non-building structures. Buildings must conform to the code to obtain planning permission, usually from a local council. The main purpose of building codes is to protect public health, safety and general welfare as they relate to the construction and occupancy of buildings and structuresfor example, the building codes in many countries require engineers to consider the effects of soil liquefaction in the design of new buildings.
Scientific misconductScientific misconduct is the violation of the standard codes of scholarly conduct and ethical behavior in the publication of professional scientific research. A Lancet review on Handling of Scientific Misconduct in Scandinavian countries provides the following sample definitions, reproduced in The COPE report 1999: Danish definition: "Intention or gross negligence leading to fabrication of the scientific message or a false credit or emphasis given to a scientist" Swedish definition: "Intention[al] distortion of the research process by fabrication of data, text, hypothesis, or methods from another researcher's manuscript form or publication; or distortion of the research process in other ways.
Near-Earth objectA near-Earth object (NEO) is any small Solar System body whose orbit brings it into proximity with Earth. By convention, a Solar System body is a NEO if its closest approach to the Sun (perihelion) is less than 1.3 astronomical units (AU). If a NEO's orbit crosses the Earth's orbit, and the object is larger than across, it is considered a potentially hazardous object (PHO). Most known PHOs and NEOs are asteroids, but a small fraction are comets. There are over 30,503 known near-Earth asteroids (NEAs) and over a hundred known short-period near-Earth comets (NECs).
Steel frameSteel frame is a building technique with a "skeleton frame" of vertical steel columns and horizontal I-beams, constructed in a rectangular grid to support the floors, roof and walls of a building which are all attached to the frame. The development of this technique made the construction of the skyscraper possible. The rolled steel "profile" or cross section of steel columns takes the shape of the letter "". The two wide flanges of a column are thicker and wider than the flanges on a beam, to better withstand compressive stress in the structure.
Through-composed musicIn the theory of musical form, through-composed music is a continuous, non-sectional, and non-repetitive piece of music. The term is typically used to describe songs, but can also apply to instrumental music. While most musical forms such as ternary form (ABA), rondo form (ABACABA), and sonata form (ABA') rely on repetition, through-composed music does not re-use material (ABCD). This constant introduction of new material is most noticeable in musical settings of poems, in contrast to the often used strophic form (AAA).
Request for proposalA request for proposal (RFP) is a document that solicits a proposal, often made through a bidding process, by an agency or company interested in procurement of a commodity, service, or valuable asset, to potential suppliers to submit business proposals. An RFP is used where the request requires technical expertise, specialized capability, or where the product or service being requested does not yet exist, and the proposal may require research and development to create whatever is being requested.
Outer spaceOuter space, commonly referred to simply as space, is the expanse that exists beyond Earth and its atmosphere and between celestial bodies. Outer space is not completely empty; it is a near-perfect vacuum containing a low density of particles, predominantly a plasma of hydrogen and helium as well as electromagnetic radiation, magnetic fields, neutrinos, dust, and cosmic rays. The baseline temperature of outer space, as set by the background radiation from the Big Bang, is .
Chrysler BuildingThe Chrysler Building is an Art Deco skyscraper on the East Side of Manhattan in New York City, at the intersection of 42nd Street and Lexington Avenue in Midtown Manhattan. At , it is the tallest brick building in the world with a steel framework, and it was the world's tallest building for 11 months after its completion in 1930. , the Chrysler is the 12th-tallest building in the city, tied with The New York Times Building. Originally a project of real estate developer and former New York State Senator William H.
