Primes

• Complementarity
  • In physics and measurement, Bohr's complementarity principle holds that wave and particle descriptions are mutually exclusive yet jointly required; conjugate observables such as position–momentum form complementary pairs.

    This sourceStates the principle of complementarity: wave and particle descriptions are mutually exclusive yet jointly required for a complete account of quantum phenomena. (

• Measurement and Disturbance
  • Quantum mechanics: Measuring the position of an electron requires a photon to interact with it, which transfers energy and momentum, disturbing the electron and making momentum measurement less precise, a phenomenon Bohr (1928) elaborated as the complementarity principle in which measurement context and apparatus are inseparable from the measured property.

    This sourceFoundational statement of the complementarity principle: measurement context and apparatus are inseparable from the property measured, formalizing photon-electron coupling as intrinsic to position–momentum measurement.

• Wave-Particle Duality
  • Attempting to determine which slit each entity traversed (acquiring path information) destroys the complementarity principle: interference pattern vanishes to the extent that the path is determined.
