  2. Binary prefix - Wikipedia

    en.wikipedia.org/wiki/Binary_prefix

    However, the capacity was also quoted "1.2 MB", [41] which was a hybrid decimal and binary notation, since the "M" meant 1000 × 1024. The precise value was 1.2288 MB (decimal) or 1.171 875 MiB (binary). The 5.25-inch Apple Disk II had 256 bytes per sector, 13 sectors per track, 35 tracks per side, or a total capacity of 116 480 bytes.

  3. Simple continued fraction - Wikipedia

    en.wikipedia.org/wiki/Simple_continued_fraction

    The simplest examples are the golden ratio φ = [1;1,1,1,1,1,...] and √ 2 = [1;2,2,2,2,...], while √ 14 = [3;1,2,1,6,1,2,1,6...] and √ 42 = [6;2,12,2,12,2,12...]. All irrational square roots of integers have a special form for the period; a symmetrical string, like the empty string (for √ 2 ) or 1,2,1 (for √ 14 ), followed by the ...

  4. 63 (number) - Wikipedia

    en.wikipedia.org/wiki/63_(number)

    The thirty-first odd number, of the simplest form +, is 63. [8] It is also the fourth Woodall number of the form n ⋅ 2 n − 1 {\displaystyle n\cdot 2^{n}-1} with n = 4 {\displaystyle n=4} , with the previous members being 1, 7 and 23 (they add to 31, the third Mersenne prime).

  5. Power of two - Wikipedia

    en.wikipedia.org/wiki/Power_of_two

    The only known powers of 2 with all digits even are 2^1 = 2, 2^2 = 4, 2^3 = 8, 2^6 = 64 and 2^11 = 2048. [11] The first 3 powers of 2 with all but last digit odd is 2^4 = 16, 2^5 = 32 and 2^9 = 512. The next such power of 2 of form 2^n should have n of at least 6 digits.

  6. Slide rule - Wikipedia

    en.wikipedia.org/wiki/Slide_rule

    It is one of the simplest analog computers. [1] [2] Slide rules exist in a diverse range of styles and generally appear in a linear, circular or cylindrical form. Slide rules manufactured for specialized fields such as aviation or finance typically feature additional scales that aid in specialized calculations particular to those fields.

  7. Universe - Wikipedia

    en.wikipedia.org/wiki/Universe

    In the widely accepted ΛCDM cosmological model, dark matter accounts for about 25.8% ± 1.1% of the mass and energy in the universe while about 69.2% ± 1.2% is dark energy, a mysterious form of energy responsible for the acceleration of the expansion of the universe. [17] Ordinary ('baryonic') matter therefore composes only 4.84% ± 0.1% of ...

  8. Entscheidungsproblem - Wikipedia

    en.wikipedia.org/wiki/Entscheidungsproblem

    In 1936, Alonzo Church and Alan Turing published independent papers [2] showing that a general solution to the Entscheidungsproblem is impossible, assuming that the intuitive notion of "effectively calculable" is captured by the functions computable by a Turing machine (or equivalently, by those expressible in the lambda calculus).

  9. Household - Wikipedia

    en.wikipedia.org/wiki/Household

    In terms of amenities, in 1975 an estimated 2% of all houses in the U.S. were without a flush toilet, 1% without electric lighting, 3% without a fixed bath or shower and 1% without piped water. [37] In 1977 an estimated 59% of the population of Canada lived in a detached house, while 8% lived in an attached house, and 33% in an apartment or ...
