They started with creating a Spiral of Theodorus; which shows that all non square numbers from 1-17 are irrational. The Spiral of Silence Theory states that we are more likely to remain silent about our opinion if we believe that the perceived majority opinion is different than ours. That it came from a book called An Absird Book of Burds makes it even more fun! That which we call Square Roots, a frightening term, is the diagonal length of extremely opposing corners.

Theodorus of Cyrene, a Greek mathematician from the 5th century BC (and possibly a tutor of Plato), is believed to have proven the irrationality of the square roots of the non-square integers up to 17. He constructed the Theodorus' wheel or the spiral wheel with 16 contiguous right triangles, in other words triangles attached to each other. He used that spiral to prove that all non-square integers from 3-17 are irrational. Download Full PDF Package.

Construction. spiral (n.). He further showed how to construct lines of these lengths via the Spiral of Theodorus. Thank you for sharing these poems! The triangles in the spiral have one side length of 1 unit long and two irrational side lengths in the form of consecutive square root numbers. 111, No. Theodorus' legacy is his contribution to mathematics in developing the irrational numbers. 1. flying downward in a helical path with a large radius 2. a structure consisting of something wound in a continuous series of loops "a coil of rope" 3. ornament consisting of a curve on a plane that winds around a center with an increasing distance from the center 4. a plane curve traced by a point circling about the center but at increasing distances from the center Permission is granted to copy, distribute and/or modify this document under the terms of the GNU Free Documentation License, Version 1.2 or any later version published by the Free Software Foundation; with no Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts.A copy of the license is included in the section entitled GNU Free Documentation License.

Plato does not attribute the irrationality of the square root of 2 to Theodorus, because it was well known before him. Spiral of Theodorus. The spiral of Theodorus is a spiral composed of right triangles.Hundreds of years ago, Theodorus of Cyrene constructed continuous right triangles and got a beautiful spiral.
