  1. Modular Arithmetic
    Modular arithmetic can be handled mathematically by introducing a congruence relation on the integers that is compatible with the operations of the ring of integers: addition, subtraction, and multiplication. For a fixed modulus n, it is defined as follows.
  2. Hebrew -- Meanings
    Hebrew is spoken by about 5 million people in Israel. In addition, it is spoken by several hundred thousand speakers in the Palestinian territories and expatriot Jewish communities around the world (Ethnologue).
  3. Goldman Sachs Group -- Investments
    Investment banks like Goldman Sachs generate profit by bundling subprime mortgages and reselling them to other investors in the form of mortgage-backed securities (MBSs). As an increasing number of subprime originators have been faced with bankruptcy (three more in June 2007 alone), both the value of existing MBSs and demand for additional MBSs have fallen significantly. This, in turn, has led to a fall in revenues for Goldman, who both securitizes mortgages and has some holdings of MBSs. Goldman has additional exposure to the subprime market in that it has made loans to several subprime lenders. The firm was the largest creditor for New Century, a subprime mortgage lender that went bankrupt in April 2007. While the exact amount of New Century's outstanding debt is unknown, it could be quite substantial.
  4. Goldman Sachs
    Goldman Sachs is the most geographically diverse of its non-commercial banking peers, such as Morgan Stanley, Merrill Lynch, and Lehman Brothers. As seen in the graph to the right, Goldman derived 46% of its 2006 revenues from the outside the US. This percentage increased to 50% in the first quarter of 2007. In addition to Goldman's long history in China, the firm is firmly entrenched in several other countries, including key emerging markets. In India, Goldman participated in a joint venture for several years and is now significantly expanding its local presence. The firm is ... well established in Japan and various European countries.
  5. Entropy Encoding -- Symbols
    Arithmetic coding is a technique for achieving near-optimal entropy encoding. An arithmetic encoder takes a string of symbols as input and produces a rational number in the interval, as output. As each symbol is processed, the encoder will restrict the output to a smaller interval. represent the probability of each symbol appearing. . Note that at each stage, all the possible intervals are pairwise disjoint. Therefore a specific sequence of symbols produces exactly one unique output range, and the process can be reversed.
  6. Welfare Economics -- Individuals
    Welfare economics is concerned with the welfare of individuals, as opposed to groups, communities, or societies because it assumes that the individual is the basic unit of measurement. It ... assumes that individuals are the best judges of their own welfare, that people will prefer greater welfare to less welfare, and that welfare can be adequately measured either in dollars (or some other unit of currency) or as a relative preference.
  7. Coins -- Miscellaneous
    Most coins presently are made of a base metal, and their value comes from their status as fiat money. This means that the value of the coin is decreed by government fiat (law), and ... is determined by the free market only as national currencies are subjected to arbitrage in international trade. This causes such coins to be monetary tokens in the same sense that paper currency is, when the paper currency is not backed directly by metal, but rather by a government guarantee of international exchange of goods or services. Some have suggested that such coins not be considered to be "true coins" (see below). However, because fiat money is backed by government guarantee of a certain amount of goods and services, where the value of this is in turn determined by free market currency exchange rates, similar to the case for the international market exchange values which determines the value of metals which back commodity money, in practice there is very little practical economic difference between the two types of money (types of currencies).

  9. Prolog -- Pure Prolog
    Prolog is a logic programming language. It is a general purpose language often associated with artificial intelligence and computational linguistics. It has a purely logical subset, called "pure Prolog", as well as a number of extralogical features.
  10. Rhetoric -- Subjects
    Rhetoric is the counterpart of Dialectic. Both alike are concerned with such things as come, more or less, within the general ken of all men and belong to no definite science. Accordingly all men make use, more or less, of both; for to a certain extent all men attempt to discuss statements and to maintain them, to defend themselves and to attack others. Ordinary people do this either at random or through practice and from acquired habit. Both ways being possible, the subject can plainly be handled systematically, for it is possible to inquire the reason why some speakers succeed through practice and others spontaneously; and every one will at once agree that such an inquiry is the function of an art.
