  2. Standard Model - Wikipedia

    en.wikipedia.org/wiki/Standard_Model

    The development of the Standard Model was driven by theoretical and experimental particle physicists alike. The Standard Model is a paradigm of a quantum field theory for theorists, exhibiting a wide range of phenomena, including spontaneous symmetry breaking, anomalies, and non-perturbative behavior.

    The Standard Model predicts that each of these three numbers should be conserved separately in a manner similar to the way baryon number is conserved. These numbers are collectively known as lepton family numbers (LF). (This result depends on the assumption made in Standard Model that neutrinos are massless.

    Complete arithmetic (also known as true arithmetic) is the theory of the standard model of arithmetic, the natural numbers N. It is complete but does not have a recursively enumerable set of axioms. It is complete but does not have a recursively enumerable set of axioms.

    The Standard Model of particle physics was finalized in the mid-1970s upon experimental confirmation of the existence of quarks.Subsequent discoveries of the top quark (1995), the tau neutrino (2000), and the Higgs boson (2013), gave the model further credence.

  7. Standard model (set theory) - Wikipedia

    en.wikipedia.org/wiki/Standard_model_(set_theory)

    A standard model M that satisfies the additional transitivity condition that x ∈ y ∈ M implies x ∈ M is a standard transitive model (or simply a transitive model). Usually, when one talks about a model M of set theory, it is assumed that M is a set model, i.e. the domain of M is a set in V.

    ASCII art of a fish. ASCII art is a graphic design technique that uses computers for presentation and consists of pictures pieced together from the 95 printable (from a total of 128) characters defined by the ASCII Standard from 1963 and ASCII compliant character sets with proprietary extended characters (beyond the 128 characters of standard 7-bit ASCII).
