  • the seventeenth letter of the English alphabet, has but one sound (that of k), and is always followed by u, the two letters together being sounded like kw, except in some words in which the u is silent. See Guide to Pronunciation, § 249. Q is not found in Anglo-Saxon, cw being used instead of qu; as in cwic, quick; cwen, queen. The name (kū) is from the French ku, which is from the Latin name of the same letter; its form is from the Latin, which derived it, through a Greek alphabet, from the Phœnician, the ultimate origin being Egyptian.

Etymologies

Sense 5, probably from German Q(uelle), source.

Examples

  • A better alternative is to take the observed values q, q², q³, ¦ as the actual elements of reality, and view Ψ just as a bookkeeping device, determined by the actual values q, q², q³,

    Relational Quantum Mechanics

  • In the last step they arbitrarily introduce a heat density source, Q, and a heat current density term, q, to represent the flow of thermal energy.

    Rabett Run

  • Also take the quantities q, q², r, r² of the above lemma (11) to be the single expectation values:

    Bell's Theorem

  • Indeed, as far as its later behavior is concerned, the combined system S+O may very well be in a quantum superposition of alternative possible values q, q², q³, ¦.

    Relational Quantum Mechanics

  • This "second observer" situation captures the core conceptual difficulty of the interpretation of quantum mechanics: reconciling the possibility of quantum superposition with the fact that the observed world is characterized by uniquely determined events q, q², q³, ¦.

    Relational Quantum Mechanics

  • But even if we can circumvent the collapse problem, the more serious difficulty of this point of view is that it appears to be impossible to understand how specific observed values q, q², q³, ¦ can emerge from the same

    Relational Quantum Mechanics

  • The problem of the interpretation of quantum mechanics takes then different forms, depending on the relative ontological weight we choose to assign to the wave function Ψ or, respectively, to the sequence of the measurement outcomes q, q², q³, ¦.

    Relational Quantum Mechanics

  • If Row and Column cooperate with probabilities p and q (and defect with probabilities p* = 1-p and q* = 1-q), for example, then the expected value of the payoff to Row is p*qT+pqR+p*q*P+pq*S.

    Prisoner's Dilemma

  • But mostly we are interested in computing (j smaller than p), and q ' title='p(x_j|z_p..q), jq ' class='latex' /.

  • Resolution is modeled after the chain rule (of which Modus Ponens is a special case) and essentially states that from p ˆ¨ q and ~q ˆ¨ r one can infer p ˆ¨
