  3. Principia Mathematica - Wikipedia

    The ramified type (τ 1,...,τ m |σ 1,...,σ n) can be modeled as the product of the type (τ 1,...,τ m,σ 1,...,σ n) with the set of sequences of n quantifiers (∀ or ∃) indicating which quantifier should be applied to each variable σ i. (One can vary this slightly by allowing the σs to be quantified in any order, or allowing them to ...

  4. Acid dissociation constant - Wikipedia

    A simple example is provided by the effect of replacing the hydrogen atoms in acetic acid by the more electronegative chlorine atom. The electron-withdrawing effect of the substituent makes ionisation easier, so successive pK a values decrease in the series 4.7, 2.8, 1.4, and 0.7 when 0, 1, 2, or 3 chlorine atoms are present.

  5. Gell-Mann–Nishijima formula - Wikipedia

    en.wikipedia.org/wiki/Gell-Mann–Nishijima_formula

    The Gell-Mann–Nishijima formula (sometimes known as the NNG formula) relates the baryon number B, the strangeness S, the isospin I 3 of quarks and hadrons to the electric charge Q. It was originally given by Kazuhiko Nishijima and Tadao Nakano in 1953, [ 1 ] and led to the proposal of strangeness as a concept, which Nishijima originally ...

    The Basel problem is a problem in mathematical analysis with relevance to number theory, concerning an infinite sum of inverse squares.It was first posed by Pietro Mengoli in 1650 and solved by Leonhard Euler in 1734, [1] and read on 5 December 1735 in The Saint Petersburg Academy of Sciences.

  7. Fibonacci sequence - Wikipedia

    en.wikipedia.org/wiki/Fibonacci_sequence

    Lucas numbers have L 1 = 1, L 2 = 3, and L n = L n−1 + L n−2. Primefree sequences use the Fibonacci recursion with other starting points to generate sequences in which all numbers are composite. Letting a number be a linear function (other than the sum) of the 2 preceding numbers. The Pell numbers have P n = 2P n−1 + P n−2.

  9. Peano axioms - Wikipedia

    en.wikipedia.org/wiki/Peano_axioms

    Axioms 1, 6, 7, 8 define a unary representation of the intuitive notion of natural numbers: the number 1 can be defined as S(0), 2 as S(S(0)), etc. However, considering the notion of natural numbers as being defined by these axioms, axioms 1, 6, 7, 8 do not imply that the successor function generates all the natural numbers different from 0.
