Vedic Mathematics is a book written by Indian Shankaracharya Bharati Krishna Tirtha and first published in 1965. It contains a list of mathematical techniques which were falsely claimed to contain advanced mathematical knowledge. [1]
In mathematics, the floor function is the function that takes as input a real number x, and gives as output the greatest integer less than or equal to x, denoted ⌊x⌋ or floor(x). Similarly, the ceiling function maps x to the least integer greater than or equal to x , denoted ⌈ x ⌉ or ceil( x ) .
The smallest non-abelian group is the symmetric group which has 3! = 6 elements. [1] 6 the answer to the two-dimensional kissing number problem. [15] A regular cube, with six faces. A cube has 6 faces. A tetrahedron has 6 edges. In four dimensions, there are a total of six convex regular polytopes.
The sol or sol de oro from 1863 to 1985, at 1 sol = 10 reales. The inti from 1985 to 1991, at 1 inti = 1,000 soles de oro. Due to the bad state of economy and hyperinflation in the late 1980s, the government was forced to abandon the inti and introduce the sol as the country's new currency. [6]
At a wavelength of 670 nm (6.7 × 10 −7 m), measured refractive index and extinction coefficient values are 3.135 and 0.897, respectively. Thickness determination yielded 3.7 Å across a 0.5mm area, consistent with the 3.35 Å reported for layer-to-layer carbon atom distance of graphite crystals. [ 113 ]
Italian "solfeggio" and English/French "solfège" derive from the names of two of the syllables used: sol and fa.[2] [3]The generic term "solmization", referring to any system of denoting pitches of a musical scale by syllables, including those used in India and Japan as well as solfège, comes from French solmisation, from the Latin solfège syllables sol and mi.
The Ringelmann effect is the tendency for individual members of a group to become increasingly less productive as the size of their group increases. [1] This effect, discovered by French agricultural engineer Maximilien Ringelmann (1861–1931), illustrates the inverse relationship that exists between the size of a group and the magnitude of group members’ individual contribution to the ...
