  2. Historical dynamics - Wikipedia

    en.wikipedia.org/wiki/Historical_dynamics

    See cyclical industrial dynamics for modeling of industries in the sense of "historical dynamics of industries". Some related terms are industrial planning, history of industry, industrial evolution, technology change, and technology forecasting. An example of "history friendly" industrial models. [18] from the journal, Industrial and Corporate ...

  3. Spacetime diagram - Wikipedia

    en.wikipedia.org/wiki/Spacetime_diagram

    The solid diagonal lines are the light cones for the observer's current event, and they intersect at that event. The small dots are other arbitrary events in the spacetime. The slope of the world line (deviation from being vertical) is the velocity of the particle on that section of the world line.

  4. Observer effect (physics) - Wikipedia

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

    In physics, the observer effect is the disturbance of an observed system by the act of observation. [1] [2] This is often the result of utilising instruments that, by necessity, alter the state of what they measure in some manner.

  5. Relativistic dynamics - Wikipedia

    en.wikipedia.org/wiki/Relativistic_dynamics

    What distinguishes relativistic dynamics from other physical theories is the use of an invariant scalar evolution parameter to monitor the historical evolution of space-time events. In a scale-invariant theory, the strength of particle interactions does not depend on the energy of the particles involved. [1]

  6. History of special relativity - Wikipedia

    en.wikipedia.org/wiki/History_of_special_relativity

    Without this postulate, it would be impossible to infer the speed of light from astronomical observations, as Ole Rømer did based on observations of the moons of Jupiter. Poincaré also noted that the propagation speed of light can be (and in practice often is) used to define simultaneity between spatially separate events:

  7. Cliodynamics - Wikipedia

    en.wikipedia.org/wiki/Cliodynamics

    Cliodynamics (/ ˌ k l iː oʊ d aɪ ˈ n æ m ɪ k s /) is a transdisciplinary area of research that integrates cultural evolution, economic history/cliometrics, macrosociology, the mathematical modeling of historical processes during the longue durée, and the construction and analysis of historical databases.

  8. Relativity of simultaneity - Wikipedia

    en.wikipedia.org/wiki/Relativity_of_simultaneity

    This derivation was completely based on light speed invariance and the relativity principle, so Einstein noted that for the electrodynamics of moving bodies the aether is superfluous. Thus, the separation into "true" and "local" times of Lorentz and Poincaré vanishes – all times are equally valid and therefore the relativity of length and ...

  9. Dynamical system - Wikipedia

    en.wikipedia.org/wiki/Dynamical_system

    The concept of a dynamical system has its origins in Newtonian mechanics.There, as in other natural sciences and engineering disciplines, the evolution rule of dynamical systems is an implicit relation that gives the state of the system for only a short time into the future.
