• Programming Language.

  Logic languages use logic as their mathematical base. A logic program consists of sets of facts and if-then rules, which specify how one set of facts may be deducedfrom others, for example: If the statement X is true, then the statement Y is false. In the execution of such a program, an input statement can be logically deduced from other statements in the program. Many artificial intelligence programs are writtenin such languages. IV LANGUAGE STRUCTURE AND COMPONENTS Programming languages use...

• Thermodynamics I INTRODUCTION Thermodynamics, field of physics that describes and correlates the physical properties of macroscopic systems of matter and energy.

  Carnot EngineThe idealized Carnot engine was envisioned by the French physicist Nicolas Léonard Sadi Carnot, who lived during theearly 19th century. The Carnot engine is theoretically perfect, that is, it converts the maximum amount of energy intomechanical work. Carnot showed that the efficiency of any engine depends on the difference between the highest andlowest temperatures reached during one cycle. The greater the difference, the greater the efficiency. An automobileengine, for example, wou...

• "A Modest Proposal" - anthology.

  I SHALL now therefore humbly propose my own Thoughts; which I hope will not be liable to the least Objection. I HAVE been assured by a very knowing American of my Acquaintance in London; that a young healthy Child, well nursed, is, at a Year old, a most delicious, nourishing, and wholesome Food; whether Stewed, Roasted, Baked, or Boiled; and, I make no doubt, that it will equally serve in a Fricasie, or Ragoust. I DO therefore humbly offer it to publick Consideration, that of...

• First Aid.

  IV SEVERE BLEEDING The presence of blood over a considerable area of a person’s body does not always indicate severe bleeding. The blood may ooze from multiple small wounds or besmeared, giving the appearance of more blood than is actually present. The rate at which blood is lost from a wound depends on the size and kind of blood vesselruptured. Bright red, spurting blood indicates injury to an artery while welling or steadily flowing, dark red blood indicates injury to a vein. Welling or spur...

• Show that chapter four of 'Things Fall Apart' is conceived in irony

  up into groups of four hundred. Sometimes, the two boys were given yams to prepare, but Okonkwo was never satisfied with their efforts. He scolded and threatened them, especially Nwoye, whom Okonkwo thought was growing up into a lazy youth. Deep inside him Okonkwo knew that the boys were too young to be preparing yams, but he also believed that it was never too early to start. Yam, the king of crops, stood for manliness, and Oknonkwo wanted his son Nwoye to grow up to become a strong farme...

• THE CONTRACT (droit anglais)

  REQUIREMENT FOR TERMS OF A CONTRACT Although contracts can be interpreted as almost any monetary exchange for goods or services, the terms of an agreement are often required so that compensation can be obtained if one party fails in its responsibilities. Without such specifications, it becomes almost impossible to seek reparations; for example, "we agree to sell/purchase a car for a fair price" is too vague for any decision to be reached at a later date. That being said, many contracts of a ve...

• Pollination - biology.

  rapidly as in cross-pollination, because one plant with a beneficial gene can transmit it only to its own offspring and not to other plants. Self-pollination evolved laterthan cross-pollination, and may have developed as a survival mechanism in harsh environments where pollinators were scarce. IV POLLEN TRANSFER Unlike animals, plants are literally rooted to the spot, and so cannot move to combine sex cells from different plants; for this reason, species have evolved effectivestrategies for ac...

• From A Vindication of the Rights of Woman - anthology.

  Ignorance is a frail base for virtue! Yet, that it is the condition for which woman was organized, has been insisted upon by the writers who have most vehementlyargued in favour of the superiority of man; a superiority not in degree, but essence; though, to soften the argument, they have laboured to prove, with chivalrousgenerosity, that the sexes ought not to be compared; man was made to reason, woman to feel: and that together, flesh and spirit, they make the most perfect whole, byblending hap...

• To have a conscience involves being conscious of the moral quality

  ends up doing the right thing. Talk of a ‘perverted' conscience may mean that a person's ultimate convictions are judged to be perverse, as in the first strand identified; or that their capacity to know good from evil, in general or in the particular case, has been distorted or corrupted. Building on the above, we may note a third emphasis in the idea of conscience, to do with the care, intensity and frequency with which someone examines the moral credentials of their desires, feelings,...

• Don Juan de Molière

  The hypocrisy of others: What is hypocrisy in general? A hypocrite is a man who intentionally appears to be what he is not in reality. What does it mean for a virtuous man to be a hypocrite? It means that the love that this man is supposed to have for the beautiful and the good isn’t the sole or prime motive of his “virtuous” actions. The virtue of most men is the result of their fear or cowardice. It is not truly virtue. Are fear and cowardice motives able to make a man virtuous? No....

• Mechanics I INTRODUCTION Mechanics, branch of physics concerning the motions of objects and their response to forces.

  Components of VelocityNeglecting air resistance, a ball thrown into the air at an angle will travel in a parabolic path. The velocity of the ball (V)has independent vertical (V) and horizontal (H) components; the horizontal component stays the same the entire time theball is in the air, while the vertical component, the only component affected by gravity, changes continuously while theball is aloft.© Microsoft Corporation.

• Communism

  access to, resources, but the underlying principle is quite similar. Rather than freeing some or even all people in a society to devote themselves to a higher cause, secular communism is designed to allow everyone to pursue personal fulfilment. It may best be characterized by a slogan adopted by Marx that appears to have been first published on the title page of Cabet's Voyage en Icarie (1840): ‘From each according to his ability, to each according to his need' . In other words, each pers...

• From "Resistance to Civil Government" - anthology.

  intending it, as God. A very few—as heroes, patriots, martyrs, reformers in the great sense, and men—serve the state with their consciences also, and so necessarily resist it for the most part; and they are commonly treated as enemies by it. A wise man will only be useful as a man, and will not submit to be “clay,” and “stop a holeto keep the wind away,” but leave that office to his dust at least: “I am too high born to be propertied,To be a second at control,Or useful serving-man and instr...

• Excerpt from Emma - anthology.

  Her sister, though comparatively but little removed by matrimony, being settled in London, only sixteen miles off, was much beyond her daily reach; and many along October and November evening must be struggled through at Hartfield, before Christmas brought the next visit from Isabella and her husband and their littlechildren to fill the house and give her pleasant society again. Highbury, the large and populous village almost amounting to a town, to which Hartfield, in spite of its separate...

• Aristotle Nicomachean Ethics

  2) Hume, enquiry concerning the principles of morals self love vs public affection The second appendix is intended to clarify the meaning of the term self-love. Does this term connote only those actions which are selfish in the narrower sense of the word, or is it possible that it includes actions which are usually called altruistic? The question arises from the fact that moral sentiments are said to have their origin in the feelings. Whose feelings are referred to in this connection? Is it...

• Trigonometry I INTRODUCTION Trigonometry, branch of mathematics that deals with the relationships between the sides and angles of triangles and with the properties and applications of the trigonometric functions of angles.

  If point P, in the definition of the general trigonometric function, is on the y-axis, x is 0; therefore, because division by zero is inadmissible in mathematics, the tangent and secant of such angles as 90°, 270°, and -270° do not exist. If P is on the x-axis, y is 0; in this case, the cotangent and cosecant of such angles as 0°, 180°, and - 180° do not exist. All angles have sines and cosines, because r is never equal to 0. Since r is greater than or equal to x or y, the values of si...

• Art, performing

  performers in instancing their work is not to say merely that performers are means for the work's transmission. Thefoundry workers who follow the sculptor's instructions and the film's projectionist help to create or transmit thework, but theirs is not the pivotal role of the performer. They might be replaced by technologically superioralternatives without thereby altering the artistic character of the statue or film, whereas the performer's task isineliminably part of works created fo...

• Luther's Ninety-Five Theses German theologian Martin Luther publicly condemned the practice of buying indulgences on October 31, 1517.

  28. It is certain that when the penny jingles into the money-box, gain and avarice can be increased, but the result of the intercession of the Church is in the power ofGod alone. 29. Who knows whether all the souls in purgatory wish to be bought out of it, as in the legend of Sts. Severinus and Paschal. 30. No one is sure that his own contrition is sincere; much less that he has attained full remission. 31. Rare as is the man that is truly penitent, so rare is also the man who truly buys indulge...

• Antibiotics.

  In some species of bacteria the cell wall consists primarily of a thick layer of peptidoglycan. Other species have a much thinner layer of peptidoglycan and an outer aswell as an inner membrane. When bacteria are subjected to Gram's stain, these differences in structure affect the differential staining of the bacteria with a dye calledgentian violet. The differences in staining coloration (gram-positive bacteria appear purple and gram-negative bacteria appear colorless or reddish, depending on t...

• La Psychiatrie est elle une science?

  distinguish science from non-science. Philosophers of science now generally agree that the search for a demarcation criterion has failed. However, in other disciplines the search for a means of distinguishing science from pseudoscience continues. I review the current debate in psychology and psychiatry. Then, returning to philosophical work, I discuss and support accounts according to which 'science' is best considered a family resemblance term. This suggests that whether psychiatric research is...

• Algebra I INTRODUCTION Algebra, branch of mathematics in which symbols (usually letters) represent unknown numbers in mathematical equations.

  B Order of Operations and Grouping Algebra relies on an established sequence for performing arithmetic operations. This ensures that everyone who executes a string of operations arrives at the sameanswer. Multiplication is performed first, then division, followed by addition, then subtraction. For example: 1 + 2 · 3 equals 7 because 2 and 3 are multiplied first and then added to 1. Exponents and roots have even higher priority than multiplication: 3 · 2 2 = 3 · 4 = 12 Grouping symbols override...

• Calculus (mathematics) I INTRODUCTION Limits This graph, which charts the function f(x)=1x, shows that the value of the function approaches zero as x becomes larger and larger.

  DerivativesThe derivative of a function at a given point is equal to the slope of the line that is tangent to the function at that givenpoint. In this example, the derivative of f(x) at x0 is defined as the slope of AB in the limit of h going to zero. As hbecomes increasingly smaller, B moves along the curve towards A, and AB increasingly approximates T, the tangent to thecurve at x0.© Microsoft Corporation. All Rights Reserved.

• Geometry I INTRODUCTION Geometry, branch of mathematics that deals with shapes and sizes.

  Conic sections, a commonly studied topic of geometry, are two-dimensional curves created by slicing a plane through a three-dimensional hollow cone. A Euclid’s Postulates Euclid, who lived about 300 BC, realized that only a small number of postulates underlay the various geometric theorems known at the time. He determined that these theorems could be deduced from just five postulates. 1. A straight line may be drawn through any two given points. 2. A straight line may be drawn infinitely or be...

  signal, such as a musical note. This form of modulation, AM, is used in many radiotelephony services including standard radiobroadcasts. AM is also employed for carriercurrent telephony, in which the modulated carrier is transmitted by wire, and in the transmission of still pictures by wire or radio. See Broadcasting, Radio and Television. In FM the frequency of the carrier wave is varied within a fixed range at a rate corresponding to the frequency of a sound signal. This form of modulation, p...

• Pottery I INTRODUCTION Pottery, clay that is chemically altered and permanently hardened by firing in a kiln.

  basket, or a clay or plaster form. Liquid clay can be poured into plaster molds. A pot can be coil built: Clay is rolled between the palms of the hands and extended intolong coils, a coil is formed into a ring, and the pot is built up by superimposing rings. Also, a ball of clay can be pinched into the desired shape. The most sophisticatedpottery-making technique is wheel throwing. The potter's wheel, invented in the 4th millennium BC, is a flat disk that revolves horizontally on a pivot. Both...

• Crafts.

  VI POTTERY Ceramic objects can be molded completely by hand or thrown (shaped) on a potter's wheel, a device with a rotating horizontal disk. When the clay hardens, it is fired ina high-temperature oven, or kiln, to strengthen it. To make the object waterproof, glazes may then be applied and the piece fired again. Although hand construction iseasy to master, throwing on the potter's wheel requires practice. Several simple tools are used by potters, including sponges, trimming tools, wooden sha...

• Commonsensism

  2 Critical commonsensism: a systematic treatment ‘The slogans are impressive enough, ' one may say, ‘but how are they to be applied? ' In setting out, one presupposes that, by contemplating various possible beliefs, we can find out that some of them logically imply others, that some contradict others, that some are such that they serve to confirm others (they make the others probable) and that some are such as to disconfirm others (they make the others improbable). Probability, as Peirce con...

• Cat. I INTRODUCTION Cat, small, mainly carnivorous animal, Felis silvestris catus, member of

  D Coat Colors The domestic cat's original coat color was probably grayish-brown with darker tabby stripes, a color that provides excellent camouflage in a variety of environments. Allother coat colors and patterns are the result of genetic mutations; for example, solid coat colors such as black and blue are the result of a gene that suppresses tabbystripes; an orange coat is the result of a gene that transforms black pigment to orange; and a solid white coat is the result of a gene that complet...

• Astronaut - astronomy.

  Every operation during a flight is important and interesting, but many might be boring to an observer. Much of an astronaut’s job is entering computer instructions,preparing samples, making measurements, recording data, fixing what breaks, and adjusting the checklist when something unexpected happens. Sometimes astronautsretrieve or repair satellites, rendezvous or dock with other spacecraft, and do important emergency repairs. The adaptability of the human crew is crucial to the successof missi...

  been created, information can be retrieved but not changed. Newer technologies allow ROMs to be semi-permanent—that is, the information can be changed, but ittakes several seconds to make the change. For example, a FLASH memory acts like a ROM because values remain stored in memory, but the values can be changed. C External Memory External memory can generally be classified as either magnetic or optical, or a combination called magneto-optical. A magnetic storage device, such as a computer'shar...

• locke-montesquieu

  I shall leave the question of Montesquieu's influence for another day. My purpose here is to give an account of the argument for religious toleration in the Persian Letters . But before I celebrate the virtues of Montesquieu, I’m afraid I have a few unpleasant things to say about Locke, whose treatment of the subject seems to me to be generally overrated. It’s a common observation that Locke's treatment of toleration is unhappily limited. His subject is "mutual toleration among Christ...

• Electronics.

  electronic circuits. The resistors are made from carbon mixtures, metal films, or resistance wire and have two connecting wires attached. Variable resistors, with anadjustable sliding contact arm, are often used to control volume on radios and television sets. E Capacitors Capacitors consist of two metal plates that are separated by an insulating material ( see Capacitor). If a battery is connected to both plates, an electric charge will flow for a short time and accumulate on each plate. If th...

• Electoral College.

  III HISTORY OF THE ELECTORAL COLLEGE A Origins One thing is clear about the political theory underpinning the electoral college: The framers of the Constitution could not agree on one. From the outset, the framerswere uncertain about how the president should be chosen. Meeting in the Constitutional Convention in Philadelphia, Pennsylvania, in 1787, the framers originally decidedto have Congress choose the president, and that there should be no popular vote to elect the president. Then the Con...

• Assisted Suicide.

  regardless of the fairness of the procedures used (substantive due process). In the Glucksberg case, the Court indicated that the liberty interest protected by the 14th Amendment does not encompass the right to determine the timing and manner of one’s own death. The Court’s decision means that each state may determine whetheror not to prohibit or permit (and otherwise regulate) assisted suicide. In 2006 the Court upheld Oregon’s law permitting physician-assisted suicide. In a 6-to-3 decision,...

  The proliferation of mandated notes that accompany financial statements is a particularly visible example. Such notes disclose information that is not already included inthe body of the financial statement. One of the very first notes identifies the accounting methods adopted when acceptable alternative methods also exist, or when theunique nature of the company's business justifies an otherwise unconventional approach.

• Relativity I INTRODUCTION Albert Einstein In 1905 German-born American physicist Albert Einstein published his first paper outlining the theory of relativity.

  in calculating very large distances or very large aggregations of matter. As the quantum theory applies to the very small, so the relativity theory applies to the verylarge. Until 1887 no flaw had appeared in the rapidly developing body of classical physics. In that year, the Michelson-Morley experiment, named after the American physicistAlbert Michelson and the American chemist Edward Williams Morley, was performed. It was an attempt to determine the rate of the motion of the earth through t...
