    In particular, since the verb "δείκνυμι" means both to show or to prove, [2] a different translation from the Greek phrase would read "The very thing it was required to have shown." [3] The Greek phrase was used by many early Greek mathematicians, including Euclid [4] and Archimedes.

    An aesthetic term referring to the ability of an idea to provide insight into mathematics, whether by unifying disparate fields, introducing a new perspective on a single field, or by providing a technique of proof which is either particularly simple, or which captures the intuition or imagination as to why the result it proves is true.

    Proof complexity, computational resources required to prove statements; Proof procedure, method for producing proofs in proof theory; Proof theory, a branch of mathematical logic that represents proofs as formal mathematical objects; Statistical proof, demonstration of degree of certainty for a hypothesis

  6. Proof (truth) - Wikipedia

    en.wikipedia.org/wiki/Proof_(truth)

    In most disciplines, evidence is required to prove something. Evidence is drawn from the experience of the world around us, with science obtaining its evidence from nature, [11] law obtaining its evidence from witnesses and forensic investigation, [12] and so on. A notable exception is mathematics, whose proofs are drawn from a mathematical ...

  7. Proof by contradiction - Wikipedia

    en.wikipedia.org/wiki/Proof_by_contradiction

    Given any number , we seek to prove that there is a prime larger than . Suppose to the contrary that no such p exists (an application of proof by contradiction). Then all primes are smaller than or equal to n {\displaystyle n} , and we may form the list p 1 , … , p k {\displaystyle p_{1},\ldots ,p_{k}} of them all.

    Challah proofing in loaf pans. Bread covered with linen proofing cloth in the background.. In cooking, proofing (also called proving) is a step in the preparation of yeast bread and other baked goods in which the dough is allowed to rest and rise a final time before baking.

  9. Direct proof - Wikipedia

    en.wikipedia.org/wiki/Direct_proof

    Traditionally, a proof is a platform which convinces someone beyond reasonable doubt that a statement is mathematically true. Naturally, one would assume that the best way to prove the truth of something like this (B) would be to draw up a comparison with something old (A) that has already been proven as true. Thus was created the concept of ...
