Three is the atomic number of lithium. Three is the ascii code of " End of Text ". Three is the number of dimensions that humans resume can perceive. Humans perceive the universe to have three spatial dimensions, but some theories, such as string theory, suggest there are more.
The triangle, a polygon with three edges and three vertices, is the most stable physical shape. For this reason it is widely utilized in construction, engineering and design. 4 The ability of the human eye to distinguish colors is based upon the varying sensitivity of different cells in the retina to light of different wavelengths. Humans being trichromatic, the retina contains three types of color receptor cells, or cones. Protoscience edit Pseudoscience edit Philosophy edit main article: Trichotomy (philosophy) Philosophers such as Aquinas, kant, hegel,. . Peirce, and Karl Popper have made threefold divisions, or trichotomies, which have been important in their work. Hegel 's dialectic of Thesis Antithesis synthesis creates three-ness from two-ness.
Three of the five platonic solids have triangular faces the tetrahedron, the octahedron, and the icosahedron. Also, three of the five platonic solids have vertices where three faces meet the tetrahedron, the hexahedron ( cube and the dodecahedron. Furthermore, only three different types of polygons comprise the faces of the five platonic solids the triangle, the square, and the pentagon. There are only three distinct 44 panmagic squares. According to pythagoras and the pythagorean school, the number 3, which they called triad, is the noblest of all digits, as it is the only number to equal the sum of all the terms below it, and the only number whose sum with those below.
2 The trisection of the angle was one of the three famous problems of antiquity. Gauss proved that every integer is the sum of at most 3 triangular numbers. Numeral systems edit There is some evidence to suggest that early man may have used counting systems which consisted of "One, two, three" and thereafter "Many" to describe counting limits. Early peoples had a word to describe the quantities of one, two, and three but any quantity beyond was simply denoted as "Many". This is most likely based on the prevalence of this phenomenon among people in such disparate regions as the deep Amazon and Borneo jungles, where western civilization's explorers have historical records of their first encounters with these indigenous people. 3 List of basic calculations edit division x. 126.96.36.199.428571.

This is true for 3 as well (with n 2 but in this case the smaller factor. If n is greater than 2, both n 1 and n 1 are greater than 1 so their product is not prime. A natural number is divisible by three if the sum of its digits in base 10 is divisible. For example, the number 21 is divisible by three (3 times 7) and the sum of its digits is 2. Because of this, the reverse of any number that is divisible by three (or indeed, any permutation of its digits) is also divisible by three. For instance, 1368 and its reverse 8631 are both divisible by three (and so are 1386, 3168, 3186, 3618, etc.). See also divisibility rule. This works in base 10 and in any positional numeral mom system whose base divided by three leaves a remainder of one (bases 4, 7, 10, etc.).
The second Lucas prime. The second triangular number. It is the only prime triangular number. The fourth Fibonacci number. The smallest number of sides that a simple (non-self-intersecting) polygon online can have. The only number for which n, n 10 and n 20 are prime. Three is the only prime which is one less than a perfect square. Any other number which is n 2 1 for some integer n is not prime, since it is ( n 1 n 1).

Brahmin, indians wrote it, and the, gupta made the three lines more curved. The nagari started rotating the lines clockwise and ending each line with a slight downward stroke on the right. Eventually, they made these strokes connect with the lines below, and evolved it to a character that looks very much like a modern 3 with an needed extra stroke at the bottom. It was the western Ghubar. Arabs who finally eliminated the extra stroke and created our modern. (The "extra" stroke, however, was very important to the eastern Arabs, and they made it much larger, while rotating the strokes above to lie along a horizontal axis, and to this day eastern Arabs write a 3 that looks like a mirrored 7 with ridges. In some French text-figure typefaces, though, it has an ascender instead of a descender. Flat top 3 edit a common variant of the digit 3 has a flat top, similar to the character Ʒ ( ezh ). This form is sometimes used to prevent people from fraudulently changing a 3 into.

This article is about the number. For the year, see. For other uses, see 3 (disambiguation), iii (disambiguation), and, number Three (disambiguation). Not to be confused with Ʒ (ezh) or (yogh). Natural number 3 ( three ) is a number, numeral, and glyph. It is the natural number following 2 and preceding. Contents, evolution of the glyph edit, three is the largest number still written with as many lines as the number represents. Ancient Romans usually wrote 4 paperless as iiii, but this was almost entirely replaced by the subtractive notation, iv in the middle Ages.) to this day 3 is written as three lines in Roman and.
