A black hole is a region of spacetime where gravity is so strong that nothing – no particles or even electromagnetic radiation such as light – can escape from it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole. The boundary of no escape is called the event horizon. Although it has a great effect on the fate and circumstances of an object crossing it, it has no locally detectable features according to general relativity. In many ways, a black hole acts like an ideal black body, as it reflects no light. Moreover, quantum field theory in curved spacetime predicts that event horizons emit Hawking radiation, with the same spectrum as a black body of a temperature inversely proportional to its mass. This temperature is of the order of billionths of a kelvin for stellar black holes, making it essentially impossible to observe directly.
A coordination complex consists of a central atom or ion, which is usually metallic and is called the coordination centre, and a surrounding array of bound molecules or ions, that are in turn known as ligands or complexing agents. Many metal-containing compounds, especially those that include transition metals, are coordination complexes.
The cosmos is another name for the Universe. Using the word cosmos implies viewing the universe as a complex and orderly system or entity.
In Einstein's theory of general relativity, the Schwarzschild metric is an exact solution to the Einstein field equations that describes the gravitational field outside a spherical mass, on the assumption that the electric charge of the mass, angular momentum of the mass, and universal cosmological constant are all zero. The solution is a useful approximation for describing slowly rotating astronomical objects such as many stars and planets, including Earth and the Sun. It was found by Karl Schwarzschild in 1916, and around the same time independently by Johannes Droste, who published his more complete and modern-looking discussion four months after Schwarzschild.
The Dialogue Concerning the Two Chief World Systems is a 1632 Italian-language book by Galileo Galilei comparing the Copernican system with the traditional Ptolemaic system. It was translated into Latin as Systema cosmicum in 1635 by Matthias Bernegger. The book was dedicated to Galileo's patron, Ferdinando II de' Medici, Grand Duke of Tuscany, who received the first printed copy on February 22, 1632.
The Nutcracker is an 1892 two-act ballet, originally choreographed by Marius Petipa and Lev Ivanov with a score by Pyotr Ilyich Tchaikovsky. The libretto is adapted from E. T. A. Hoffmann's 1816 short story "The Nutcracker and the Mouse King".
Tony Joe White, nicknamed the Swamp Fox, was an American singer-songwriter and guitarist, best known for his 1969 hit "Polk Salad Annie" and for "Rainy Night in Georgia", which he wrote but which was first made popular by Brook Benton in 1970. He also wrote "Steamy Windows" and "Undercover Agent for the Blues", both hits for Tina Turner in 1989; those two songs came by way of Turner's producer at the time, Mark Knopfler, who was a friend of White. "Polk Salad Annie" was also recorded by Joe Dassin, Elvis Presley, and Tom Jones.
An astronomical clock, horologium, or orloj is a clock with special mechanisms and dials to display astronomical information, such as the relative positions of the Sun, Moon, zodiacal constellations, and sometimes major planets.
Afro-Cuban jazz is the earliest form of Latin jazz. It mixes Afro-Cuban clave-based rhythms with jazz harmonies and techniques of improvisation.Afro-Cuban music has deep roots in African ritual and rhythm. Afro-Cuban jazz emerged in the early 1940s with the Cuban musicians Mario Bauzá and Frank Grillo "Machito" in the band Machito and his Afro-Cubans in New York City. In 1947, the collaborations of bebop trumpeter Dizzy Gillespie and percussionist Chano Pozo brought Afro-Cuban rhythms and instruments, such as the tumbadora and the bongo, into the East Coast jazz scene. Early combinations of jazz with Cuban music, such as "Manteca" and "Mangó Mangüé", were commonly referred to as "Cubop" for Cuban bebop.
