Besides describing the way documents can be viewed and edited, the concepts of "portrait" and "landscape" orientation can also be used to describe video and photography display options (where the concept of "aspect ratio" replaces that of "page orientation"). [3] Many types of visual media use landscape mode, especially the 4:3 aspect ratio ...
The trisection of the angle was one of the three famous problems of antiquity. 3 is the number of non-collinear points needed to determine a plane, a circle, and a parabola. There are only three distinct 4×4 panmagic squares. Three of the five Platonic solids have triangular faces – the tetrahedron, the octahedron, and the icosahedron.
For example, the aspect ratio of a rectangle is the ratio of its longer side to its shorter side—the ratio of width to height, [1] [2] when the rectangle is oriented as a "landscape". The aspect ratio is most often expressed as two integer numbers separated by a colon (x:y), less commonly as a simple or decimal fraction. The values x and y do ...
The Erdős number measures the "collaborative distance" between an author and Erdős. Thus, his direct co-authors have Erdős number one, theirs have number two, and so forth. Erdős himself has Erdős number zero. There are more than 12,500 [1] people with an Erdős number of two.
This is a list of articles about prime numbers. A prime number (or prime) is a natural number greater than 1 that has no positive divisors other than 1 and itself. By Euclid's theorem, there are an infinite number of prime numbers. Subsets of the prime numbers may be generated with various formulas for primes.
Also amphidrome and tidal node. A geographical location where there is little or no tide, i.e. where the tidal amplitude is zero or nearly zero because the height of sea level does not change appreciably over time (meaning there is no high tide or low tide), and around which a tidal crest circulates once per tidal period (approximately every 12 hours). Tidal amplitude increases, though not ...
This list contains a list of EC numbers for the third group, EC 3, hydrolases, placed in numerical order as determined by the Nomenclature Committee of the International Union of Biochemistry and Molecular Biology. All official information is tabulated at the website of the committee. [1] The database is developed and maintained by Andrew McDonald.
For every 3 non-theme words you find, you earn a hint. Hints show the letters of a theme word. If there is already an active hint on the board, a hint will show that word’s letter order.
