Onyx

Onyx is a banded variety of the oxide mineral chalcedony. Agate and onyx are both varieties of layered chalcedony that differ only in the form of the bands: agate has curved bands and onyx has parallel bands. The colors of its bands range from white to almost every color (save some shades, such as purple or blue). Commonly, specimens of onyx contain bands of black and/or white.

Etymology

Onyx comes through Latin (of the same spelling), from the Greek ὄνυξ, meaning "claw" or "fingernail". With its fleshtone color, onyx can be said to resemble a fingernail. The English word "nail" is cognate with the Greek word.

Varieties

Onyx is formed of bands of chalcedony in alternating colors. It is cryptocrystalline, consisting of fine intergrowths of the silica minerals quartz and moganite. Its bands are parallel to one another, as opposed to the more chaotic banding that often occurs in agates.

Sardonyx is a variant in which the colored bands are sard (shades of red) rather than black. Black onyx is perhaps the most famous variety, but is not as common as onyx with colored bands. Artificial treatments have been used since ancient times to produce both the black color in "black onyx" and the reds and yellows in sardonyx. Most "black onyx" on the market is artificially colored.

USS Onyx (PYc-5)

USS Onyx (PYc-5), was a diesel coastal patrol yacht of the United States Navy during World War II.

The ship was built in 1924 as Janey III by Consolidated Shipbuilding Corp. of Morris Heights, New York, and was subsequently renamed Rene and Pegasus.

Purchased by the Navy on 3 December 1940 from Clifford C. Hemphill, of New York City, converted to Navy use and named Onyx, she was classified as a coastal yacht on 13 December 1940, and commissioned on 27 February 1941.

Service history

After conversion she departed New York for Norfolk, arriving on 22 March. Sailing again, she reached New Orleans on 5 April to report for duty to Commandant 8th Naval District. Onyx performed services for ComEight as a coastal patrol vessel around the Gulf area until January 1942. On 22 January she departed Key West, Florida to return to New York and arrived there on 31 January.

Onyx was again ordered to report to the 8th Naval District at New Orleans and was underway by 13 March, arriving on 27 March. She resumed services and continued in this capacity until February 1944 when she was extensively damaged in a collision. Beyond economic repair, her ordnance was removed and she was placed out of commission, in service, retaining her name and designation, on 15 May 1944. She was designated a target vessel on 31 May, the same year, and made available for disposition on 31 October.

Sunlight

Sunlight is a portion of the electromagnetic radiation given off by the Sun, in particular infrared, visible, and ultraviolet light. On Earth, sunlight is filtered through Earth's atmosphere, and is obvious as daylight when the Sun is above the horizon. When the direct solar radiation is not blocked by clouds, it is experienced as sunshine, a combination of bright light and radiant heat. When it is blocked by the clouds or reflects off other objects, it is experienced as diffused light. The World Meteorological Organization uses the term "sunshine duration" to mean the cumulative time during which an area receives direct irradiance from the Sun of at least 120 watts per square meter.

The ultraviolet radiation in sunlight has both positive and negative health effects, as it is both a principal source of vitamin D₃ and a mutagen.

Summary

Researchers may record sunlight using a sunshine recorder, pyranometer, or pyrheliometer.

Sunlight takes about 8.3 minutes to reach Earth from the surface of the Sun. A photon starting at the centre of the Sun and changing direction every time it encounters a charged particle would take between 10,000 and 170,000 years to get to the surface.

Sunlight (album)

Sunlight is a June 1978 jazz-funk, fusion album by keyboardist Herbie Hancock. It features Hancock's vocals through a vocoder as well as performances by drummer Tony Williams and bassist Jaco Pastorius. This was when Hancock began heading towards a more mainstream Smooth Jazz/R&B fusion, similar to fellow Jazz-Fusion pianist Patrice Rushen. This would last until his 1982 album Lite Me Up.

The album produced a single entitled "I Thought It Was You" which was mildly received at the time by UK jazz listeners. As a whole the album tends to lay more toward funk than a jazz record, and is reminiscent of much of the electro-funk of the time. This release marks the beginning of the 1980s electro-era style that was more refined in Herbie's later albums such as Future Shock and Sound-System.
