  2. Behavioural change theories - Wikipedia

    en.wikipedia.org/wiki/Behavioural_change_theories

    Each behavioural change theory or model focuses on different factors in attempting to explain behaviour change. Of the many that exist, the most prevalent are learning theories, social cognitive theory, theories of reasoned action and planned behaviour, transtheoretical model of behavior change, the health action process approach, and the BJ Fogg model of behavior change.

  3. Lunar effect - Wikipedia

    en.wikipedia.org/wiki/Lunar_effect

    Moonrise by the Sea.Biologists as well as artists and poets have long thought about the Moon's influence on living creatures. The lunar effect is a purported correlation between specific stages of the roughly 29.5-day lunar cycle and behavior and physiological changes in living beings on Earth, including humans.

  4. Entrainment (chronobiology) - Wikipedia

    en.wikipedia.org/wiki/Entrainment_(chronobiology)

    In the study of chronobiology, entrainment refers to the synchronization of a biological clock to an environmental cycle. An example is the interaction between circadian rhythms and environmental cues, such as light and temperature. Entrainment helps organisms adapt their bodily processes according to the timing of a changing environment. [1]

  6. Optics - Wikipedia

    en.wikipedia.org/wiki/Optics

    In the late 1660s and early 1670s, Isaac Newton expanded Descartes's ideas into a corpuscle theory of light, famously determining that white light was a mix of colours that can be separated into its component parts with a prism. In 1690, Christiaan Huygens proposed a wave theory for light based on suggestions that had been made by Robert Hooke ...

  7. Period-doubling bifurcation - Wikipedia

    en.wikipedia.org/wiki/Period-doubling_bifurcation

    Period doubling in the Kuramoto–Sivashinsky equation with periodic boundary conditions. The curves depict solutions of the Kuramoto–Sivashinsky equation projected onto the energy phase plane (E, dE/dt), where E is the L 2-norm of the solution. For ν = 0.056, there exists a periodic orbit with period T ≈ 1.1759.

  8. Zitterbewegung - Wikipedia

    en.wikipedia.org/wiki/Zitterbewegung

    Zitterbewegung appears as due to the "small components" of the Dirac 4-spinor, due to a little bit of antiparticle mixed up in the particle wavefunction for a nonrelativistic motion. It doesn't appear in the correct second quantized theory, or rather, it is resolved by using Feynman propagators and doing QED. Nevertheless, it is an interesting ...

  9. Social cycle theory - Wikipedia

    en.wikipedia.org/wiki/Social_cycle_theory

    Social cycle theories are among the earliest social theories in sociology.Unlike the theory of social evolutionism, which views the evolution of society and human history as progressing in some new, unique direction(s), sociological cycle theory argues that events and stages of society and history generally repeat themselves in cycles.
