Mathematical Joke
A mathematical joke is a form of humor which relies on aspects of mathematics or a stereotype of mathematicians. The humor may come from a pun, or from a double meaning of a mathematical term, or from a lay person's misunderstanding of a mathematical concept. Mathematician and author John Allen Paulos in his book ''Mathematics and Humor'' described several ways that mathematics, generally considered a dry, formal activity, overlaps with humor, a loose, irreverent activity: both are forms of "intellectual play"; both have "logic, pattern, rules, structure"; and both are "economical and explicit". Some performers combine mathematics and jokes to entertain and/or teach math. Humor of mathematicians may be classified into the esoteric and exoteric categories. Esoteric jokes rely on the intrinsic knowledge of mathematics and its terminology. Exoteric jokes are intelligible to the outsiders, and most of them compare mathematicians with representatives of other disciplines or with com ...

Volume Of A Pizza
Volume is a Measure (mathematics), measure of Region (mathematics), regions in three-dimensional space. It is often quantified numerically using SI derived units (such as the cubic metre and litre) or by various imperial units, imperial or United States customary units, US customary units (such as the gallon, quart, cubic inch). The definition of length and height (cubed) is interrelated with volume. The volume of a container is generally understood to be the capacity of the container; i.e., the amount of fluid (gas or liquid) that the container could hold, rather than the amount of space the container itself displaces. By metonymy, the term "volume" sometimes is used to refer to the corresponding region (e.g., bounding volume). In ancient times, volume was measured using similar-shaped natural containers. Later on, standardized containers were used. Some simple Three dimensional, three-dimensional shapes can have their volume easily calculated using arithmetic formulas. Volume ...

Dictionary of Forestry. or flatcar#Skeleton car, skeleton cars. In forestry, the term logging is sometimes used narrowly to describe the logistics of moving wood from the stump to somewhere outside the forest, usually a sawmill or a lumber yard. In common usage, however, the term may cover a range of forestry or silviculture activities. Logging is the beginning of a supply chain that provides raw material for many products societies worldwide use for housing, construction, energy, and consumer paper products.

Halloween
Halloween, or Hallowe'en (less commonly known as Allhalloween, All Hallows' Eve, or All Saints' Eve), is a celebration geography of Halloween, observed in many countries on 31 October, the eve of the Western Christianity, Western Christian feast of All Saints' Day, All Hallows' Day. It is at the beginning of the observance of Allhallowtide, the time in the Christian liturgical year dedicated to remembering the dead, including saints (hallows), Christian martyr, martyrs, and all the faithful departed. In popular culture, Halloween has become a celebration of Horror fiction, horror and is associated with the macabre and the supernatural. One theory holds that many Halloween traditions were influenced by Celts, Celtic harvest festivals, particularly the Gaels, Gaelic festival Samhain, which are believed to have Paganism, pagan roots. Some theories go further and suggest that Samhain may have been Christianization, Christianized as All Hallows' Day, along with its eve, by the Ear ...

Radix
In a positional numeral system, the radix (radices) or base is the number of unique digits, including the digit zero, used to represent numbers. For example, for the decimal system (the most common system in use today) the radix is ten, because it uses the ten digits from 0 through 9. In any standard positional numeral system, a number is conventionally written as with ''x'' as the string of digits and ''y'' as its base. For base ten, the subscript is usually assumed and omitted (together with the enclosing parentheses), as it is the most common way to express value. For example, (the decimal system is implied in the latter) and represents the number one hundred, while (100)2 (in the binary system with base 2) represents the number four. Etymology ''Radix'' is a Latin word for "root". ''Root'' can be considered a synonym for ''base,'' in the arithmetical sense. In numeral systems Generally, in a system with radix ''b'' (), a string of digits denotes the number , ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Binary Numeral System
A binary number is a number expressed in the base-2 numeral system or binary numeral system, a method for representing numbers that uses only two symbols for the natural numbers: typically "0" ( zero) and "1" ( one). A ''binary number'' may also refer to a rational number that has a finite representation in the binary numeral system, that is, the quotient of an integer by a power of two. The base-2 numeral system is a positional notation with a radix of 2. Each digit is referred to as a bit, or binary digit. Because of its straightforward implementation in digital electronic circuitry using logic gates, the binary system is used by almost all modern computers and computer-based devices, as a preferred system of use, over various other human techniques of communication, because of the simplicity of the language and the noise immunity in physical implementation. History The modern binary number system was studied in Europe in the 16th and 17th centuries by Thomas Harrio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Houseboat
A houseboat is a boat that has been designed or modified to be used primarily for regular dwelling. Most houseboats are not motorized, as they are usually moored or kept stationary, fixed at a Berth (moorings), berth, and often tethered to land to provide utilities. However, many are capable of operation under their own power. Houseboats are largely found on small inland rivers, lakes, and streams, and in coastal harbours, especially where there is good fishing, in many countries. Africa South Africa There are a few houseboat options in South Africa, including self-drive houseboats on the Knysna, Knysna Lagoon and fully catered houseboats on Pongolapoort Dam, Lake Jozini. There have been a number of serious incidents with houseboat fires in the country. On 19 November 2016, four people died on Hartbeespoort Dam after a fire broke on a party houseboat. On 9 October 2021, a faulty engine set luxury houseboat ''Shayamanzi'' afire and led to the death of two crew members and a ...

Log Cabin
A log cabin is a small log house, especially a minimally finished or less architecturally sophisticated structure. Log cabins have an ancient history in Europe, and in America are often associated with first-generation home building by settlers. History Europe Construction with logs was described by Roman architect Vitruvius Pollio in his architectural treatise ''De Architectura''. He noted that in Pontus in present-day northeastern Turkey, dwellings were constructed by laying logs horizontally overtop of each other and filling in the gaps with "chips and mud". Log cabin construction has its roots in Scandinavia and Eastern Europe. Although their precise origin is uncertain, the first log structures were probably being built in Northern Europe by the Bronze Age around 3500 BC. C. A. Weslager describes Europeans as having: A medieval log cabin was considered movable property, evidenced by the relocation of Espåby in 1557, where the buildings were disassembled, transpo ...

Constant Of Integration
In calculus, the constant of integration, often denoted by C (or c), is a constant term added to an antiderivative of a function f(x) to indicate that the indefinite integral of f(x) (i.e., the set of all antiderivatives of f(x)), on a connected domain, is only defined up to an additive constant. This constant expresses an ambiguity inherent in the construction of antiderivatives. More specifically, if a function f(x) is defined on an interval, and F(x) is an antiderivative of f(x), then the set of ''all'' antiderivatives of f(x) is given by the functions F(x) + C, where C is an arbitrary constant (meaning that ''any'' value of C would make F(x) + C a valid antiderivative). For that reason, the indefinite integral is often written as \int f(x) \, dx = F(x) + C, although the constant of integration might be sometimes omitted in lists of integrals for simplicity. Origin The derivative of any constant function is zero. Once one has found one antiderivative F(x) for a function f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Natural Logarithm
The natural logarithm of a number is its logarithm to the base of a logarithm, base of the e (mathematical constant), mathematical constant , which is an Irrational number, irrational and Transcendental number, transcendental number approximately equal to . The natural logarithm of is generally written as , , or sometimes, if the base is implicit, simply . Parentheses are sometimes added for clarity, giving , , or . This is done particularly when the argument to the logarithm is not a single symbol, so as to prevent ambiguity. The natural logarithm of is the exponentiation, power to which would have to be raised to equal . For example, is , because . The natural logarithm of itself, , is , because , while the natural logarithm of is , since . The natural logarithm can be defined for any positive real number as the Integral, area under the curve from to (with the area being negative when ). The simplicity of this definition, which is matched in many other formulas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antiderivative
In calculus, an antiderivative, inverse derivative, primitive function, primitive integral or indefinite integral of a continuous function is a differentiable function whose derivative is equal to the original function . This can be stated symbolically as . The process of solving for antiderivatives is called antidifferentiation (or indefinite integration), and its opposite operation is called ''differentiation'', which is the process of finding a derivative. Antiderivatives are often denoted by capital Roman letters such as and . Antiderivatives are related to definite integrals through the second fundamental theorem of calculus: the definite integral of a function over a closed interval where the function is Riemann integrable is equal to the difference between the values of an antiderivative evaluated at the endpoints of the interval. In physics, antiderivatives arise in the context of rectilinear motion (e.g., in explaining the relationship between position, veloc ...

Gravity's Rainbow
''Gravity's Rainbow'' is a 1973 novel by the American writer Thomas Pynchon. The narrative is set primarily in Europe at the end of World War II and centers on the design, production and dispatch of V-2 rockets by the German military. In particular, it features the quest undertaken by several characters to uncover the secret of a mysterious device, the ("black device"), which is slated to be installed in a rocket with the serial number "00000". Traversing a wide range of knowledge, ''Gravity's Rainbow'' crosses boundaries between high and low culture, between literary propriety and profanity, and between science and speculative metaphysics. It shared the 1974 US National Book Award for Fiction with ''A Crown of Feathers and Other Stories'' by Isaac Bashevis Singer. Although selected by the Pulitzer Prize jury on fiction for the 1974 Pulitzer Prize for Fiction, the Pulitzer Advisory Board was offended by its content, some of which was described as 'unreadable', 'turgid', 'overwr ...

Variable (mathematics)
In mathematics, a variable (from Latin language, Latin ) is a Mathematical symbol, symbol, typically a letter, that refers to an unspecified mathematical object. One says colloquially that the variable ''represents'' or ''denotes'' the object, and that any valid candidate for the object is the value (mathematics), value of the variable. The values a variable can take are usually of the same kind, often numbers. More specifically, the values involved may form a Set (mathematics), set, such as the set of real numbers. The object may not always exist, or it might be uncertain whether any valid candidate exists or not. For example, one could represent two integers by the variables and and require that the value of the square of is twice the square of , which in algebraic notation can be written . A definitive proof that this relationship is impossible to satisfy when and are restricted to integer numbers isn't obvious, but it has been known since ancient times and has had a big ...
