  2. Methods of computing square roots - Wikipedia

    en.wikipedia.org/wiki/Methods_of_computing...

    A method analogous to piece-wise linear approximation but using only arithmetic instead of algebraic equations, uses the multiplication tables in reverse: the square root of a number between 1 and 100 is between 1 and 10, so if we know 25 is a perfect square (5 × 5), and 36 is a perfect square (6 × 6), then the square root of a number greater than or equal to 25 but less than 36, begins with ...

    en.wikipedia.org/wiki/Russian_alphabet

    Although Russian word stress is often unpredictable and can fall on different syllables in different forms of the same word, the diacritic accent is used only in dictionaries, children's books, resources for foreign-language learners, the defining entry (in bold) in articles on Russian Wikipedia, or on minimal pairs distinguished only by stress ...

  4. Neutrino - Wikipedia

    en.wikipedia.org/wiki/Neutrino

    From cosmological arguments, relic background neutrinos are estimated to have density of 56 of each type per cubic centimeter and temperature 1.9 K (1.7 × 10 −4 eV) if they are massless, much colder if their mass exceeds 0.001 eV/c 2. Although their density is quite high, they have not yet been observed in the laboratory, as their energy is ...

  5. Temperature - Wikipedia

    where the Boltzmann constant k B is the ideal gas constant divided by the Avogadro number, and = = is the root-mean-square speed. [86] This direct proportionality between temperature and mean molecular kinetic energy is a special case of the equipartition theorem , and holds only in the classical limit of a perfect gas .

    Thus, a lens set to f /1.4 allows twice as much light to strike the focal plane as a lens set to f / 2. Therefore, each f-number factor of the square root of two (approximately 1.4) is also a stop, so lenses are typically marked in that progression: f / 1.4, 2, 2.8, 4, 5.6, 8, 11, 16, 22, 32, etc..
