    Etymology: from approximate.

  1. Approximation

    An approximation is anything that is intentionally similar but not exactly equal to something else.


  1. approximation

    Approximation refers to a representation or estimation of a value or quantity that is nearly correct but not exact, typically as a result of certain assumptions or calculations. This idea is used frequently in mathematics, computing, and science to achieve results that are close to the true value but more practical to calculate or use.

Webster Dictionary

  1. Approximationnoun

    the act of approximating; a drawing, advancing or being near; approach; also, the result of approximating

  2. Approximationnoun

    an approach to a correct estimate, calculation, or conception, or to a given quantity, quality, etc

  3. Approximationnoun

    a continual approach or coming nearer to a result; as, to solve an equation by approximation

  4. Approximationnoun

    a value that is nearly but not exactly correct

  5. Etymology: [Cf. F. approximation, LL. approximatio.]


  1. Approximation

    An approximation is anything that is similar but not exactly equal to something else. This applies to anything that is nearly but not exactly correct; similar, but not exactly the same. Although approximation is most often applied to numbers, it is also frequently applied to such things as mathematical functions, shapes, and physical laws. Approximations might be used if incomplete information prevents use of exact representations. For instance, some problems in physics are too complex to solve by direct analysis, or progress could be limited by available analytical tools. Thus, even when the exact representation is known, an approximation may yield a sufficiently accurate solution while reducing the complexity of the problem significantly. For instance, physicists often approximate the shape of the Earth as a sphere even though more accurate representations are possible, because many physical behaviours are much easier to calculate for a sphere than for other shapes. It is difficult to exactly analyze the motion of several planets orbiting a star, for example, due to the complex interactions of the planets' gravitational effects on each other, so an approximate solution is effected by performing iterations. In the first iteration, the planets' gravitational interactions are ignored, and the star is assumed to be fixed. If a more precise solution is desired, another iteration is then performed, using the positions and motions of the planets as identified in the first iteration, but adding a first-order gravity interaction from each planet on the others. This process may be repeated until a satisfactorily precise solution is obtained. The use of perturbations to correct for the errors can yield more accurate solutions. Simulations of the motions of the planets and the star also yields more accurate solutions.

Examples of approximation in a Sentence

  1. Bertrand Russell:

    All exact science is dominated by the idea of approximation.

  2. Alex Tihonov/Adobe Stock Photo ChatGPT:

    It’s worth noting that while a language model like Alex Tihonov/Adobe Stock Photo ChatGPT can provide an approximation of a sermon, it can not replicate the full experience of a live sermon delivered by a human preacher, the human element of preaching, including voice inflection, emotional expression, and audience interaction, is an important part of the preaching experience that a language model can not replicate.

  3. Anis Aouini:

    This project that is planned for India consisting of 50 Saphonians producing 20 kilowatts of power, a total of one mega watt, will be a wind farm. This power produced in south India, could meet the demands of a small village of 1000 houses even if the energy will be directly injected to the general Indian electricity network. But it's an approximation to ease the understanding for viewers: it's about 1000 houses in India.

  4. American Enterprise Institute.Jason Furman:

    I think to a first approximation the forward looking proposals would have very little impact on inflation because they're spread out over time and give the Fed a lot of time to react and are mostly paid for.

  5. Aristotle:

    It is the mark of an educated mind to rest satisfied with the degree of precision which the nature of the subject admits and not to seek exactness where only an approximation is possible.
