  2. Mathematical coincidence - Wikipedia

    en.wikipedia.org/wiki/Mathematical_coincidence

    This is a pure coincidence, as the metre was originally defined as 1 / 10 000 000 of the distance between the Earth's pole and equator along the surface at sea level, and the Earth's circumference just happens to be about 2/15 of a light-second. [39] It is also roughly equal to one foot per nanosecond (the actual number is 0.9836 ft/ns).

    A second of arc, arcsecond (abbreviated as arcsec), or arc second, denoted by the symbol ″, [2] is a unit of angular measurement equal to ⁠ 1 / 60 ⁠ of a minute of arc, ⁠ 1 / 3600 ⁠ of a degree, [1] ⁠ 1 / 1 296 000 ⁠ of a turn, and ⁠ π / 648 000 ⁠ (about ⁠ 1 / 206 264.8 ⁠) of a radian.

    It was 7 feet [2.1 m] through 10 feet [3.0 m] from the stump, and 5 feet [1.5 m] through 50 feet [15 m] from the stump. Twenty-two logs were taken from the tree, the average length of which were 12 feet [3.7 m]. Fourteen feet [4.3 m] of the tree were spoiled in falling.

  6. Scale (map) - Wikipedia

    en.wikipedia.org/wiki/Scale_(map)

    A graphical or bar scale. A map would also usually give its scale numerically ("1:50,000", for instance, means that one cm on the map represents 50,000cm of real space, which is 500 meters) A bar scale with the nominal scale expressed as "1:600 000", meaning 1 cm on the map corresponds to 600,000 cm=6 km on the ground.

  7. Millimetre - Wikipedia

    Different lengths as in respect to the electromagnetic spectrum, measured by the metre and its derived scales.The microwave is between 1 meter to 1 millimeter.. The millimetre (international spelling; SI unit symbol mm) or millimeter (American spelling) is a unit of length in the International System of Units (SI), equal to one thousandth of a metre, which is the SI base unit of length.

  8. Four fours - Wikipedia

    en.wikipedia.org/wiki/Four_fours

    Now, we can rewrite the base (1/2) with only 4s and the exponent (1/2) back to a square root: = / ⁡ ⁡ ⏟ We have used four fours and now the number of square roots we add equals whatever non-negative integer we wanted.

  9. Rounding - Wikipedia

    en.wikipedia.org/wiki/Rounding

    For example, 1.6 would be rounded to 1 with probability 0.4 and to 2 with probability 0.6. Stochastic rounding can be accurate in a way that a rounding function can never be. For example, suppose one started with 0 and added 0.3 to that one hundred times while rounding the running total between every addition.
