  2. Division by zero - Wikipedia

    en.wikipedia.org/wiki/Division_by_zero

    For example, using single-precision IEEE arithmetic, if x = −2 −149, then x/2 underflows to −0, and dividing 1 by this result produces 1/(x/2) = −∞. The exact result −2 150 is too large to represent as a single-precision number, so an infinity of the same sign is used instead to indicate overflow.

  3. Energy efficiency in transport - Wikipedia

    A motorised bicycle allows human power and the assistance of a 49 cm 3 (3.0 cu in) engine, giving a range of 160 to 200 mpg ‑US (1.51.2 L/100 km; 190–240 mpg ‑imp). [ citation needed ] Electric pedal-assisted bikes run on as little as 1.0 kWh (3.6 MJ) per 100 km, [ 55 ] while maintaining speeds in excess of 30 km/h (19 mph).

    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 ...

    Archimedes gives the value of the square root of 3 as lying between ⁠ 265 / 153 ⁠ (approximately 1.7320261) and ⁠ 1351 / 780 ⁠ (approximately 1.7320512) in Measurement of a Circle. The actual value is approximately 1.7320508, making this a very accurate estimate. He introduced this result without offering any explanation of how he had ...

    In 2023, a Science paper estimated that at 1.5 °C (2.7 °F), one quarter of mountain glacier mass would be lost by 2100 and nearly half would be lost at 4 °C (7.2 °F), contributing ~ 9 cm (3 + 12 in) and ~15 cm (6 in) to sea level rise, respectively. Glacier mass is disproportionately concentrated in the most resilient glaciers.

    Graphene exhibits high electron mobility at room temperature, with values reported in excess of 15 000 cm 2 ⋅V −1 ⋅s −1. [2] Hole and electron mobilities are nearly identical. [ 73 ] The mobility is independent of temperature between 10 K and 100 K , [ 32 ] [ 79 ] [ 80 ] showing minimal change even at room temperature (300 K), [ 2 ...
