  2. Time loop - Wikipedia

    en.wikipedia.org/wiki/Time_loop

    The time loop is a popular trope in Japanese pop culture media, especially anime. [15] Its use in Japanese fiction dates back to Yasutaka Tsutsui's science fiction novel The Girl Who Leapt Through Time (1965), one of the earliest works to feature a time loop, about a high school girl who repeatedly relives the same day.

  3. Quantum mechanics of time travel - Wikipedia

    en.wikipedia.org/wiki/Quantum_mechanics_of_time...

    is the initial density matrix of the system before the time loop. is a transformation operator derived from the trace operation over the CTC, applied to the unitary evolution operator . The transformation relies on the trace operation, which summarizes aspects of the matrix.

  4. Optic radiation - Wikipedia

    en.wikipedia.org/wiki/Optic_radiation

    A lesion in the temporal lobe that results in damage to Meyer's loop causes a characteristic loss of vision in a superior quadrant (quadrantanopia or "pie in the sky" defect.) Fibers from the superior retina* travel straight back through the parietal lobe to the occipital lobe in the retrolenticular limb of the internal capsule to the visual ...

  5. Time constant - Wikipedia

    en.wikipedia.org/wiki/Time_constant

    First order LTI systems are characterized by the differential equation + = where τ represents the exponential decay constant and V is a function of time t = (). The right-hand side is the forcing function f(t) describing an external driving function of time, which can be regarded as the system input, to which V(t) is the response, or system output.

  6. Closed timelike curve - Wikipedia

    en.wikipedia.org/wiki/Closed_timelike_curve

    A closed timelike curve can be created if a series of such light cones are set up so as to loop back on themselves, so it would be possible for an object to move around this loop and return to the same place and time that it started. An object in such an orbit would repeatedly return to the same point in spacetime if it stays in free fall.

  7. Temporal feedback - Wikipedia

    en.wikipedia.org/wiki/Temporal_feedback

    Within molecular and cell biology, temporal feedback, also referred to as interlinked or interlocked feedback, is a biological regulatory motif in which fast and slow positive feedback loops are interlinked to create "all or none" switches. This interlinking produces separate, adjustable activation and de-activation times.

  8. Quadrantanopia - Wikipedia

    en.wikipedia.org/wiki/Quadrantanopia

    A lesion affecting one side of the temporal lobe may cause damage to the inferior optic radiations (known as the temporal pathway or Meyer's loop) which can lead to superior quadrantanopia on the contralateral side of both eyes (colloquially referred to as "pie in the sky"); if the superior optic radiations (parietal pathway) are lesioned, the ...

  9. Temporal paradox - Wikipedia

    en.wikipedia.org/wiki/Temporal_paradox

    The "predestination paradox" is a concept in time travel and temporal mechanics, often explored in science fiction. It occurs when a future event is the cause of a past event, which in turn becomes the cause of the future event, forming a self-sustaining loop in time.
