  2. Tinbergen's four questions - Wikipedia

    en.wikipedia.org/wiki/Tinbergen's_four_questions

    How vs. why questions: Proximate view How an individual organism's structures function Ontogeny (development) Developmental explanations for changes in individuals, from DNA to their current form Mechanism (causation) Mechanistic explanations for how an organism's structures work Ultimate (evolutionary) view

  3. Proximate and ultimate causation - Wikipedia

    en.wikipedia.org/wiki/Proximate_and_ultimate...

    A possible proximate explanation states that one male produced a more intense signal, leading to elevated hormone levels in the female producing copulatory behaviour. Although the behavior in these two examples is the same, the explanations are based on different sets of factors incorporating evolutionary versus physiological factors.

  4. Proximate - Wikipedia

    en.wikipedia.org/wiki/Proximate

    Proximates are used in the analysis of biological materials as a decomposition of a human-consumable good into its major constituents. They are a good approximation of the contents of packaged comestible goods and serve as a cost-effective and easy verification of nutritional panels.

    63.8 Gs: The approximate time since the beginning of the Anno Domini era as of 2019 – 2,019 years, and traditionally the time since the birth of Jesus Christ. 194.67 Gs: The approximate lifespan of time capsule Crypt of Civilization, 28 May 1940 – 28 May 8113 363 Gs: (11.5 ka): The time since the beginning of the Holocene epoch

  6. Absolute space and time - Wikipedia

    en.wikipedia.org/wiki/Absolute_space_and_time

    Absolute, true and mathematical time, of itself, and from its own nature flows equably without regard to anything external, and by another name is called duration: relative, apparent and common time, is some sensible and external (whether accurate or unequable) measure of duration by the means of motion, which is commonly used instead of true ...

  7. Approximation - Wikipedia

    en.wikipedia.org/wiki/Approximation

    An approximate model is used to make calculations easier. Approximations might also be used if incomplete information prevents use of exact representations. The type of approximation used depends on the available information , the degree of accuracy required , the sensitivity of the problem to this data, and the savings (usually in time and ...

  8. Approximate computing - Wikipedia

    en.wikipedia.org/wiki/Approximate_computing

    Approximate computing is an emerging paradigm for energy-efficient and/or high-performance design. [1] It includes a plethora of computation techniques that return a possibly inaccurate result rather than a guaranteed accurate result, and that can be used for applications where an approximate result is sufficient for its purpose.

  9. Multiple time dimensions - Wikipedia

    en.wikipedia.org/wiki/Multiple_time_dimensions

    Multiple independent timeframes, in which time passes at different rates, have long been a feature of stories. [15] Fantasy writers such as J. R. R. Tolkien and C. S. Lewis have made use of these and other multiple time dimensions, such as those proposed by Dunne, in some of their most well-known stories. [15]
