    The equation in whatever form, usually <math>equation in LaTeX...</math>. The default equation is the general form of a complex number. Example <math> z = e^{i \phi} = x + iy </math> Content: required: Reference label: ref: Label for the equation for later reference. Calls {{EquationRef}} with provided value as the parameter. Example 1: String ...

    en.wikipedia.org/wiki/Help:Displaying_a_formula

    The templates {} and {{EquationRef}} can be used to number equations. The template {{EquationNote}} can be used to refer to a numbered equation from surrounding text. For example, the following syntax: {{NumBlk |: |< math > x ^ 2 + y ^ 2 + z ^ 2 = 1 </ math >|{{EquationRef | 1}}}} produces the following result (note the equation number in the ...

  5. Proton - Wikipedia

    en.wikipedia.org/wiki/Proton

    Since each element is identified by the number of protons in its nucleus, each element has its own atomic number, which determines the number of atomic electrons and consequently the chemical characteristics of the element. The word proton is Greek for "first", and the name was given to the hydrogen nucleus by Ernest Rutherford in 1920.

  6. Bethe formula - Wikipedia

    where ρ is the density of the material, Z its atomic number, A its relative atomic mass, N A the Avogadro number and M u the Molar mass constant. In the figure to the right, the small circles are experimental results obtained from measurements of various authors, while the red curve is Bethe's formula. [ 4 ]

  7. Proton–proton chain - Wikipedia

    en.wikipedia.org/wiki/Proton–proton_chain

    The total energy yield of one whole chain is 26.73 MeV. Energy released as gamma rays will interact with electrons and protons and heat the interior of the Sun. Also kinetic energy of fusion products (e.g. of the two protons and the 4 2 He from the p–p I reaction) adds energy to the plasma in the Sun.

  8. Feynman diagram - Wikipedia

    en.wikipedia.org/wiki/Feynman_diagram

    The collection of all the φ(A) on the starting hypersurface give the field's initial value, analogous to the starting position for a point particle, and the field values φ(B) at each point of the final hypersurface defines the final field value, which is allowed to vary, giving a different amplitude to end up at different values. This is the ...

    In the case of our word, 11 such patterns can be matched, namely 1 c 4 l 4, 1 cy, 1 d 4 i 3 a, 4 edi, e 3 dia, 2 i 1 a, ope 5 d, 2 p 2 ed, 3 pedi, pedia 4, y 1 c. For each position in the word, TeX will calculate the maximum value obtained among all matching patterns, yielding en 1 cy 1 c 4 l 4 o 3 p 4 e 5 d 4 i 3 a 4.
