    en.wikipedia.org/wiki/Help:Displaying_a_formula

    Avoid formulas in section headings, and when this is necessary, use raw HTML (see Finite field for an example) The choice between {{ math }} and LaTeX depends on the editor. Converting a page from one format to another must be done with stronger reasons than editor preference.

  5. Mathematical descriptions of the electromagnetic field

    en.wikipedia.org/wiki/Mathematical_descriptions...

    If the matter field is taken so as to describe the interaction of electromagnetic fields with the Dirac electron given by the four-component Dirac spinor field ψ, the current and charge densities have form: [2] = † = †, where α are the first three Dirac matrices. Using this, we can re-write Maxwell's equations as:

    Most of the time, such as in Internet Explorer and Google Toolbar, the entries depend on the form field's name, so as to not enter street names in a last name field or vice versa. For this use, proposed names for such form fields, in earlier HTML 5 specifications this RFC is no longer referenced, thus leaving the selection of names up to each ...

  7. Debye length - Wikipedia

    Substituting this length scale into the Debye–Hückel equation and neglecting the second and third terms on the right side yields the much simplified form () = ().As the only characteristic length scale in the Debye–Hückel equation, sets the scale for variations in the potential and in the concentrations of charged species.

    Presentation metadata: how the attribute is to be displayed to the user (e.g., as a text box or image of specified dimensions, a pull-down list or a set of radio buttons). When a compound object is composed of multiple attributes, as in the EAV/CR design, there is additional metadata on the order in which the attributes should be presented, and ...
