  2. Doorway effect - Wikipedia

    en.wikipedia.org/wiki/Doorway_effect

    The doorway effect or location updating effect is a replicable psychological phenomenon characterized by short-term memory loss when passing through a doorway or ...

  3. Maxwell's demon - Wikipedia

    en.wikipedia.org/wiki/Maxwell's_demon

    In the thought experiment, a demon controls a door between two chambers containing gas. As individual gas molecules (or atoms) approach the door, the demon quickly opens and closes the door to allow only fast-moving molecules to pass through in one direction, and only slow-moving molecules to pass through in the other.

  4. Center of percussion - Wikipedia

    Effects of a blow on a hanging beam. CP is the Center of Percussion, and CM is the Center of Mass of the beam. Imagine a rigid beam suspended from a wire by a fixture that can slide freely along the wire at point P, as shown in the Figure. An impulsive blow is applied from the left.

  5. Quantum tunnelling - Wikipedia

    en.wikipedia.org/wiki/Quantum_tunnelling

    From the equations, the power series must start with at least an order of to satisfy the real part of the equation; for a good classical limit starting with the highest power of the Planck constant possible is preferable, which leads to = = and = = (), with the following constraints on the lowest order terms, () = (()) and () =

  6. Stack effect - Wikipedia

    en.wikipedia.org/wiki/Stack_effect

    The stack effect or chimney effect is the movement of air into and out of buildings through unsealed openings, chimneys, flue-gas stacks, or other purposefully designed openings or containers, resulting from air buoyancy. Buoyancy occurs due to a difference in indoor-to-outdoor air density resulting from temperature and moisture differences ...

  7. List of relativistic equations - Wikipedia

    en.wikipedia.org/wiki/List_of_relativistic_equations

    This is the formula for the relativistic doppler shift where the difference in velocity between the emitter and observer is not on the x-axis. There are two special cases of this equation. The first is the case where the velocity between the emitter and observer is along the x-axis. In that case θ = 0, and cos θ = 1, which gives:

  8. Action (physics) - Wikipedia

    en.wikipedia.org/wiki/Action_(physics)

    The action is defined by an integral, and the classical equations of motion of a system can be derived by minimizing the value of that integral. The action principle provides deep insights into physics, and is an important concept in modern theoretical physics. Various action principles and related concepts are summarized below.

  9. Ladder paradox - Wikipedia

    en.wikipedia.org/wiki/Ladder_paradox

    The effect of the impact can propagate outward from A no faster than the speed of light, so the back of the ladder will never feel the effects of the impact until point F (note the 45° angle of the line A-F, corresponding to the speed of light transmission of information) or later, at which time the ladder is well within the garage in both frames.
