Larimar is the tradename for a rare blue variety of the silicate mineral pectolite found only in the Dominican Republic, around the city of Barahona. [4] Its coloration varies from bluish white, light-blue, light-green, green-blue, turquoise blue, turquoise green, turquoise blue-green, deep green, dark green, to deep blue, dark blue and purple, violet and indigo and the larimar can come in ...
The Penrose–Hawking singularity theorems define a singularity to have geodesics that cannot be extended in a smooth manner. [6] The termination of such a geodesic is considered to be the singularity. Modern theory asserts that the initial state of the universe, at the beginning of the Big Bang, was a singularity. [7]
Pulhamite. Waterfall in Albion Place Gardens, Ramsgate. Pulhamite was a patented anthropic rock material invented by James Pulham (1820–1898) of the firm James Pulham and Son of Broxbourne in Hertfordshire. It was widely used for rock gardens and grottos.
Initial singularity. The initial singularity is a singularity predicted by some models of the Big Bang theory to have existed before the Big Bang. [1] The instant immediately following the initial singularity is part of the Planck epoch, the earliest period of time in the history of our universe.
Addie Viola Smith (1893–1975) was an American attorney who served as the U.S. trade commissioner to Shanghai from 1928 to 1939, the first female Foreign Service officer in the U.S. Foreign Service to work under the Commerce Department, and the first woman to serve as trade commissioner. A native of Stockton, California, Smith moved to ...
Milnor number. In mathematics, and particularly singularity theory, the Milnor number, named after John Milnor, is an invariant of a function germ. If f is a complex-valued holomorphic function germ then the Milnor number of f, denoted μ (f), is either a nonnegative integer, or is infinite. It can be considered both a geometric invariant and ...
The technological singularity —or simply the singularity[1] —is a hypothetical future point in time at which technological growth becomes uncontrollable and irreversible, resulting in unforeseeable consequences for Human civilization. [2][3] According to the most popular version of the singularity hypothesis, I. J. Good 's intelligence ...
Mathematical singularity, a point at which a given mathematical object is not defined or not "well-behaved", for example infinite or not differentiable. Geometry. Singular point of a curve, where the curve is not given by a smooth embedding of a parameter. Singular point of an algebraic variety, a point where an algebraic variety is not locally ...
