  2. Money multiplier - Wikipedia

    en.wikipedia.org/wiki/Money_multiplier

    In some simplified expositions, the monetary multiplier is presented as simply the reciprocal of the reserve ratio, if any, required by the central bank. More generally, the multiplier will depend on the preferences of households , the legal regulation and the business policies of commercial banks - factors which the central bank can influence ...

  3. Pi - Wikipedia

    en.wikipedia.org/wiki/Pi

    The number π (/ p aɪ / ⓘ; spelled out as "pi") is a mathematical constant, approximately equal to 3.14159, that is the ratio of a circle's circumference to its diameter.It appears in many formulae across mathematics and physics, and some of these formulae are commonly used for defining π, to avoid relying on the definition of the length of a curve.

  4. Gini coefficient - Wikipedia

    en.wikipedia.org/wiki/Gini_coefficient

    The Italian statistician Corrado Gini developed the Gini coefficient and published it in his 1912 paper Variabilità e mutabilità (English: variability and mutability). [16] [17] Building on the work of American economist Max Lorenz, Gini proposed using the difference between the hypothetical straight line depicting perfect equality and the actual line depicting people's incomes as a measure ...

  5. Special relativity - Wikipedia

    en.wikipedia.org/wiki/Special_relativity

    In 1851, Fizeau conducted an experiment to answer this question, a simplified representation of which is illustrated in Fig. 5-1. A beam of light is divided by a beam splitter, and the split beams are passed in opposite directions through a tube of flowing water.

  6. Formula One engines - Wikipedia

    en.wikipedia.org/wiki/Formula_One_engines

    The old 2.5 L formula had been retained for International Formula racing, but this did not achieve much success until the introduction of the Tasman Series in Australia and New Zealand during the winter season, leaving the 1.5 L cars as the fastest single seaters in Europe during this time. The power range was between 150 hp (112 kW) and 225 hp ...

    [4] [5] He created the first global projection of the world, incorporating parallels and meridians based on the available geographic knowledge of his era. [ 4 ] Eratosthenes was the founder of scientific chronology ; [ 6 ] he used Egyptian and Persian records to estimate the dates of the main events of the Trojan War , dating the sack of Troy ...

  8. PageRank - Wikipedia

    en.wikipedia.org/wiki/PageRank

    A probability is expressed as a numeric value between 0 and 1. A 0.5 probability is commonly expressed as a "50% chance" of something happening. Hence, a document with a PageRank of 0.5 means there is a 50% chance that a person clicking on a random link will be directed to said document.

  9. Viscosity - Wikipedia

    en.wikipedia.org/wiki/Viscosity

    The CGS unit is the poise (P, or g·cm −1 ·s −1 = 0.1 Pa·s), [28] named after Jean Léonard Marie Poiseuille. It is commonly expressed, particularly in ASTM standards, as centipoise (cP). The centipoise is convenient because the viscosity of water at 20 °C is about 1 cP, and one centipoise is equal to the SI millipascal second (mPa·s).
