WebUnit Imaginary Number. The square root of minus one √ (−1) is the "unit" Imaginary Number, the equivalent of 1 for Real Numbers. In mathematics the symbol for √ (−1) is i for … Web10 Nov 2016 · The proof of the irrationality of root 2 is often attributed to Hippasus of Metapontum, a member of the Pythagorean cult. He is said to have been murdered for his discovery (though historical evidence is rather murky) as the Pythagoreans didn't like the idea of irrational numbers. Here’s one of the most elegant proofs in the history of maths.

The square root of 2 (approximately 1.4142) is a positive real number that, when multiplied by itself, equals the number 2. It may be written in mathematics as $${\displaystyle {\sqrt {2}}}$$ or $${\displaystyle 2^{1/2}}$$, and is an algebraic number. Technically, it should be called the principal square root … See more The Babylonian clay tablet YBC 7289 (c. 1800–1600 BC) gives an approximation of $${\displaystyle {\sqrt {2}}}$$ in four sexagesimal figures, 1 24 51 10, which is accurate to about six decimal digits, and is the closest possible … See more A short proof of the irrationality of $${\displaystyle {\sqrt {2}}}$$ can be obtained from the rational root theorem, that is, if $${\displaystyle p(x)}$$ is a monic polynomial with … See more One interesting property of $${\displaystyle {\sqrt {2}}}$$ is $${\displaystyle \!\ {1 \over {{\sqrt {2}}-1}}={\sqrt {2}}+1}$$ See more Paper size In 1786, German physics professor Georg Christoph Lichtenberg found that any sheet of paper whose long edge is $${\displaystyle {\sqrt {2}}}$$ times longer than its short edge could be folded in half and aligned with its … See more Computation algorithms There are many algorithms for approximating $${\displaystyle {\sqrt {2}}}$$ as a ratio of integers or as a decimal.
