  2. 3C-model - Wikipedia

    en.wikipedia.org/wiki/3C-model

    The 3H-model of motivation ("3H" stands for the "three components of motivation") was developed by Hugo M. Kehr of UC Berkeley. The 3C-model is an integrative, empirically validated theory of motivation that can be used for systematic motivation diagnosis and intervention.

  3. Derivation of the Schwarzschild solution - Wikipedia

    en.wikipedia.org/wiki/Derivation_of_the...

    In deriving the Schwarzschild metric, it was assumed that the metric was vacuum, spherically symmetric and static. The static assumption is unneeded, as Birkhoff's theorem states that any spherically symmetric vacuum solution of Einstein's field equations is stationary; the Schwarzschild solution thus follows

  4. Heuristic-systematic model of information processing - Wikipedia

    en.wikipedia.org/wiki/Heuristic-systematic_model...

    The limitation of HSM exists in the inability to define the specific motivations of persuasion, which is why Chaiken expanded HSM to illustrate that heuristic and systematic processing can "serve defense-motivation, the desire to form or defend particular attitudinal positions, and impression- motivation, the desire to form or hold socially ...

  5. Karl Schwarzschild - Wikipedia

    en.wikipedia.org/wiki/Karl_Schwarzschild

    Karl Schwarzschild (German: [kaʁl ˈʃvaʁtsʃɪlt] ⓘ; 9 October 1873 – 11 May 1916) was a German physicist and astronomer.. Schwarzschild provided the first exact solution to the Einstein field equations of general relativity, for the limited case of a single spherical non-rotating mass, which he accomplished in 1915, the same year that Einstein first introduced general relativity.

  6. Kruskal–Szekeres coordinates - Wikipedia

    en.wikipedia.org/wiki/Kruskal–Szekeres_coordinates

    The maximally extended Schwarzschild geometry can be divided into 4 regions each of which can be covered by a suitable set of Schwarzschild coordinates. The Kruskal–Szekeres coordinates, on the other hand, cover the entire spacetime manifold. The four regions are separated by event horizons.

  7. Heuristic (computer science) - Wikipedia

    en.wikipedia.org/wiki/Heuristic_(computer_science)

    In mathematical optimization and computer science, heuristic (from Greek εὑρίσκω "I find, discover" [1]) is a technique designed for problem solving more quickly when classic methods are too slow for finding an exact or approximate solution, or when classic methods fail to find any exact solution in a search space.

  8. Schwarzschild metric - Wikipedia

    en.wikipedia.org/wiki/Schwarzschild_metric

    In Einstein's theory of general relativity, the Schwarzschild metric (also known as the Schwarzschild solution) is an exact solution to the Einstein field equations that describes the gravitational field outside a spherical mass, on the assumption that the electric charge of the mass, angular momentum of the mass, and universal cosmological constant are all zero.

  9. Social heuristics - Wikipedia

    en.wikipedia.org/wiki/Social_heuristics

    Under this theory, cooperating in everyday social situations tends to be successful, and as a result, cooperation is an internalized heuristic that is applied in unfamiliar social contexts, even those in which such behavior may not lead to the most personally advantageous result for the actor (such as a lab experiment).
