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 ...
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.
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]

The stone arrangement takes the form of an irregular egg-shape or ovoid about 50 m (164 ft) in diameter with its major axis aligning east-west. [3] It is composed of about 100 basalt stones, ranging from small rocks about 200 mm (8 in) in diameter to standing stones about 1 m (3 ft) high with an estimated total mass of about 23 t (23 long tons).

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 ...
The Makapansgat pebble is a 260-gram, 8.3 cm long, 7 cm wide, and 3.8 cm thick, reddish-brown jasperite cobble. [2] The pebble was found in 1925 in a dolomite cave in the Makapan Valley north of Mokopane, South Africa by a local school teacher Wilfred Eitzman. [3] Importantly, it was found at 4.8 km/3 miles from the nearest possible natural ...
Milnor map. In mathematics, Milnor maps are named in honor of John Milnor, who introduced them to topology and algebraic geometry in his book Singular Points of Complex Hypersurfaces (Princeton University Press, 1968) and earlier lectures. The most studied Milnor maps are actually fibrations, and the phrase Milnor fibration is more commonly ...
