    [1] [4] [3] However, "A" [citation needed] or "A.U." [11] [7] may be used in less formal contexts or typographically limited media. The angstrom is often used in the natural sciences and technology to express sizes of atoms , molecules , microscopic biological structures, and lengths of chemical bonds , arrangement of atoms in crystals , [ 12 ...

  3. Orders of magnitude (length) - Wikipedia

    en.wikipedia.org/wiki/Orders_of_magnitude_(length)

    The micrometre (SI symbol: μm) is a unit of length in the metric system equal to 10 −6 metres (⁠ 1 / 1 000 000 ⁠ m = 0. 000 001 m). To help compare different orders of magnitude , this section lists some items with lengths between 10 −6 and 10 −5 m (between 1 and 10 micrometers , or μm).

  4. Debye - Wikipedia

    en.wikipedia.org/wiki/Debye

    [note 2] Historically the debye was defined as the dipole moment resulting from two charges of opposite sign but an equal magnitude of 10 −10 statcoulomb [note 3] (generally called e.s.u. (electrostatic unit) in older scientific literature), which were separated by 1 ångström. [note 4] This gave a convenient unit for molecular dipole moments.

  5. Narcissistic number - Wikipedia

    en.wikipedia.org/wiki/Narcissistic_number

    In number theory, a narcissistic number [1] [2] (also known as a pluperfect digital invariant (PPDI), [3] an Armstrong number [4] (after Michael F. Armstrong) [5] or a plus perfect number) [6] in a given number base is a number that is the sum of its own digits each raised to the power of the number of digits.

  6. Barn (unit) - Wikipedia

    en.wikipedia.org/wiki/Barn_(unit)

    A barn (symbol: b) is a metric unit of area equal to 10 −28 m 2 (100 fm 2).Originally used in nuclear physics for expressing the cross sectional area of nuclei and nuclear reactions, today it is also used in all fields of high-energy physics to express the cross sections of any scattering process, and is best understood as a measure of the probability of interaction between small particles.

  8. Armstrong limit - Wikipedia

    en.wikipedia.org/wiki/Armstrong_limit

    The Armstrong limit or Armstrong's line is a measure of altitude above which atmospheric pressure is sufficiently low that water boils at the normal temperature of the human body. Exposure to pressure below this limit results in a rapid loss of consciousness, followed by a series of changes to cardiovascular and neurological functions, and ...
