  2. E series of preferred numbers - Wikipedia

    en.wikipedia.org/wiki/E_series_of_preferred_numbers

    The first standard was accepted in Paris in 1950, then published as IEC 63 in 1952. [12] The official values of the E3 / E6 / E12 series are subsets of the following official E24 values. Comparison of rounded log-scaled values and official values of E24 series ( m = 24 {\displaystyle m=24} )

  3. IEEE 754 - Wikipedia

    en.wikipedia.org/wiki/IEEE_754

    The IEEE Standard for Floating-Point Arithmetic (IEEE 754) is a technical standard for floating-point arithmetic originally established in 1985 by the Institute of Electrical and Electronics Engineers (IEEE). The standard addressed many problems found in the diverse floating-point implementations that made them difficult to use reliably and ...

  4. Guitar tunings - Wikipedia

    en.wikipedia.org/wiki/Guitar_tunings

    In standard tuning, there is an interval of a major third between the second and third strings, and all the other intervals are fourths. The irregularity has a price. Chords cannot be shifted around the fretboard in the standard tuning E–A–D–G–B–E, which requires four chord-shapes for the major chords.

  5. Expected value - Wikipedia

    en.wikipedia.org/wiki/Expected_value

    Any definition of expected value may be extended to define an expected value of a multidimensional random variable, i.e. a random vector X. It is defined component by component, as E[X] i = E[X i]. Similarly, one may define the expected value of a random matrix X with components X ij by E[X] ij = E[X ij].

  6. e-Stewards - Wikipedia

    en.wikipedia.org/wiki/E-Stewards

    The e-Stewards Initiative is an electronics waste recycling standard created by the Basel Action Network.. The program and the organization that created it grew out of the concern that electronic waste generated in wealthy countries was being dismantled in poor countries, often by underage workers.

  7. Standard temperature and pressure - Wikipedia

    en.wikipedia.org/wiki/Standard_temperature_and...

    Because many definitions of standard temperature and pressure differ in temperature significantly from standard laboratory temperatures (e.g. 0 °C vs. ~28 °C), reference is often made to "standard laboratory conditions" (a term deliberately chosen to be different from the term "standard conditions for temperature and pressure", despite its ...

    The data below tabulates standard electrode potentials (E°), in volts relative to the standard hydrogen electrode (SHE), at: Temperature 298.15 K (25.00 °C; 77.00 °F); Effective concentration (activity) 1 mol/L for each aqueous or amalgamated (mercury-alloyed) species; Unit activity for each solvent and pure solid or liquid species; and
