  2. Redundancy principle (biology) - Wikipedia

    en.wikipedia.org/wiki/Redundancy_principle_(biology)

    The time for the fastest particles to reach a target in the context of redundancy depends on the numbers and the local geometry of the target. In most of the time, it is the rate of activation. This rate should be used instead of the classical Smoluchowski's rate describing the mean arrival time, but not the fastest. The statistics of the ...

  3. Theoretical chemistry - Wikipedia

    en.wikipedia.org/wiki/Theoretical_chemistry

    Theoretical chemistry is the branch of chemistry which develops theoretical generalizations that are part of the theoretical arsenal of modern chemistry: for example, the concepts of chemical bonding, chemical reaction, valence, the surface of potential energy, molecular orbitals, orbital interactions, and molecule activation.

  4. Tautology (rule of inference) - Wikipedia

    en.wikipedia.org/wiki/Tautology_(rule_of_inference)

    Theorems are those logical formulas where is the conclusion of a valid proof, [4] while the equivalent semantic consequence indicates a tautology.. The tautology rule may be expressed as a sequent:

  5. Quantum error correction - Wikipedia

    en.wikipedia.org/wiki/Quantum_error_correction

    That these codes allow indeed for quantum computations of arbitrary length is the content of the quantum threshold theorem, found by Michael Ben-Or and Dorit Aharonov, which asserts that you can correct for all errors if you concatenate quantum codes such as the CSS codes—i.e. re-encode each logical qubit by the same code again, and so on, on ...

  7. Marcus theory - Wikipedia

    en.wikipedia.org/wiki/Marcus_theory

    In theoretical chemistry, Marcus theory is a theory originally developed by Rudolph A. Marcus, starting in 1956, to explain the rates of electron transfer reactions – the rate at which an electron can move or jump from one chemical species (called the electron donor) to another (called the electron acceptor). [1]

  9. Symmetry breaking - Wikipedia

    en.wikipedia.org/wiki/Symmetry_breaking

    This is an important exemption from Goldstone's theorem, where a Nambu-Goldstone boson can gain mass, becoming a Higgs boson in the process. [5] Further, in this context the usage of 'symmetry breaking' while standard, is a misnomer, as gauge 'symmetry' is not really a symmetry but a redundancy in the description of the system.
