  2. API gravity - Wikipedia

    en.wikipedia.org/wiki/API_gravity

    The American Petroleum Institute gravity, or API gravity, is a measure of how heavy or light a petroleum liquid is compared to water: if its API gravity is greater than 10, it is lighter and floats on water; if less than 10, it is heavier and sinks.

  3. Quadratic equation - Wikipedia

    en.wikipedia.org/wiki/Quadratic_equation

    A lesser known quadratic formula, as used in Muller's method, provides the same roots via the equation =. This can be deduced from the standard quadratic formula by Vieta's formulas, which assert that the product of the roots is c/a.

  4. Template:Super Formula Lights - Wikipedia

    en.wikipedia.org/wiki/Template:Super_Formula_Lights

    To change this template's initial visibility, the |state= parameter may be used: {{Super Formula Lights | state = collapsed}} will show the template collapsed, i.e. hidden apart from its title bar. {{Super Formula Lights | state = expanded}} will show the template expanded, i.e. fully visible.

  5. Flat-field correction - Wikipedia

    en.wikipedia.org/wiki/Flat-field_correction

    Flat-field correction (FFC) is a digital imaging technique to mitigate the image detector pixel-to-pixel sensitivity and distortions in the optical path. It is a standard calibration procedure in everything from personal digital cameras to large telescopes.

  6. Prism dioptre - Wikipedia

    en.wikipedia.org/?title=Prism_dioptre&redirect=no

    To a related topic: This is a redirect to an article about a similar topic.. Redirects from related topics are different than redirects from related words, because a related topic is more likely to warrant a full and detailed description in the target article.

  7. Precision tests of QED - Wikipedia

    en.wikipedia.org/wiki/Precision_tests_of_QED

    Precision tests of QED have been performed in low-energy atomic physics experiments, high-energy collider experiments, and condensed matter systems. The value of α is obtained in each of these experiments by fitting an experimental measurement to a theoretical expression (including higher-order radiative corrections) that includes α as a parameter.

  8. Category:Formula E team templates - Wikipedia

    en.wikipedia.org/wiki/Category:Formula_E_team...

    If the template has a separate documentation page (usually called "Template:template name/doc"), add [[Category:Formula E team templates]] to the <includeonly> section at the bottom of that page.

  9. Continuity correction - Wikipedia

    en.wikipedia.org/wiki/Continuity_correction

    Before the ready availability of statistical software having the ability to evaluate probability distribution functions accurately, continuity corrections played an important role in the practical application of statistical tests in which the test statistic has a discrete distribution: it had a special importance for manual calculations.
