3D Printing
3D printing or additive manufacturing is the construction of a three-dimensional object from a CAD model or a digital 3D model. It can be done in a variety of processes in which material is deposited, joined or solidified under computer control, with material being added together (such as plastics, liquids or powder grains being fused), typically layer by layer. In the 1980s, 3D printing techniques were considered suitable only for the production of functional or aesthetic prototypes, and a more appropriate term for it at the time was rapid prototyping. , the precision, repeatability, and material range of 3D printing have increased to the point that some 3D printing processes are considered viable as an industrial-production technology, whereby the term ''additive manufacturing'' can be used synonymously with ''3D printing''. One of the key advantages of 3D printing is the ability to produce very complex shapes or geometries that would be otherwise impossible to construct ...

Americium
Americium is a synthetic radioactive chemical element with the symbol Am and atomic number 95. It is a transuranic member of the actinide series, in the periodic table located under the lanthanide element europium, and thus by analogy was named after the Americas. Americium was first produced in 1944 by the group of Glenn T. Seaborg from Berkeley, California, at the Metallurgical Laboratory of the University of Chicago, as part of the Manhattan Project. Although it is the third element in the transuranic series, it was discovered fourth, after the heavier curium. The discovery was kept secret and only released to the public in November 1945. Most americium is produced by uranium or plutonium being bombarded with neutrons in nuclear reactors – one tonne of spent nuclear fuel contains about 100 grams of americium. It is widely used in commercial ionization chamber smoke detectors, as well as in neutron sources and industrial gauges. Several unusual applications, such ...

DJ AM
Adam Michael Goldstein (March 30, 1973 – August 28, 2009), known professionally as DJ AM, was an American disc jockey (DJ). Born in Philadelphia, Goldstein became interested in deejaying as a child after watching Herbie Hancock perform his 1983 single " Rockit". Goldstein developed a drug addiction as a teenager and was sent to the controversial rehabilitation center Straight, Incorporated. After he left the center, his drug problems became worse; he was addicted to crack cocaine for several years in his early twenties. After he attempted suicide in 1997, Goldstein became sober and later sponsored other addicts through Alcoholics Anonymous. Goldstein began deejaying in clubs in Los Angeles and joined the band Crazy Town in 1999. He left the group in 2001 and focused on a career as a solo DJ. After he began dating Nicole Richie in 2003, his career skyrocketed. In 2006, he accepted a $1 million contract to perform weekly at Caesars Palace on the Las Vegas strip and was ...

AM Broadcasting
AM broadcasting is radio broadcasting using amplitude modulation (AM) transmissions. It was the first method developed for making audio radio transmissions, and is still used worldwide, primarily for medium wave (also known as "AM band") transmissions, but also on the longwave and shortwave radio bands. The earliest experimental AM transmissions began in the early 1900s. However, widespread AM broadcasting was not established until the 1920s, following the development of vacuum tube receivers and transmitters. AM radio remained the dominant method of broadcasting for the next 30 years, a period called the " Golden Age of Radio", until television broadcasting became widespread in the 1950s and received most of the programming previously carried by radio. Subsequently, AM radio's audiences have also greatly shrunk due to competition from FM (frequency modulation) radio, Digital Audio Broadcasting (DAB), satellite radio, HD (digital) radio, Internet radio, music streaming ser ...

Australian Museum
The Australian Museum is a heritage-listed museum at 1 William Street, Sydney central business district, New South Wales, Australia. It is the oldest museum in Australia,Design 5, 2016, p.1 and the fifth oldest natural history museum in the world, with an international reputation in the fields of natural history and anthropology. It was first conceived and developed along the contemporary European model of an encyclopedic warehouse of cultural and natural history and features collections of vertebrate and invertebrate zoology, as well as mineralogy, palaeontology and anthropology. Apart from exhibitions, the museum is also involved in Indigenous studies research and community programs. In the museum's early years, collecting was its main priority, and specimens were commonly traded with British and other European institutions. The scientific stature of the museum was established under the curatorship of Gerard Krefft, himself a published scientist. The museum is located at t ...

Hull Classification Symbol
The United States Navy, United States Coast Guard, and United States National Oceanic and Atmospheric Administration (NOAA) use a hull classification symbol (sometimes called hull code or hull number) to identify their ships by type and by individual ship within a type. The system is analogous to the pennant number system that the Royal Navy and other European and Commonwealth navies use. History United States Navy The U.S. Navy began to assign unique Naval Registry Identification Numbers to its ships in the 1890s. The system was a simple one in which each ship received a number which was appended to its ship type, fully spelled out, and added parenthetically after the ship's name when deemed necessary to avoid confusion between ships. Under this system, for example, the battleship ''Indiana'' was USS ''Indiana'' (Battleship No. 1), the cruiser ''Olympia'' was USS ''Olympia'' (Cruiser No. 6), and so on. Beginning in 1907, some ships also were referred to alternativ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chord Names And Symbols (popular Music)
Musicians use various kinds of chord names and symbols in different contexts to represent musical chords. In most genres of popular music, including jazz, pop, and rock, a chord name and its corresponding symbol typically indicate one or more of the following: # the root note (e.g. C), # the chord quality (e.g. minor or lowercase m, or the symbols or + for diminished and augmented chords, respectively; chord quality is usually omitted for major chords), # whether the chord is a triad, seventh chord, or an extended chord (e.g. 7), # any altered notes (e.g. sharp five, or 5), # any added tones (e.g. add2), and # the bass note if it is not the root (e.g. a slash chord). For instance, the name C augmented seventh, and the corresponding symbol C, or C, are both composed of parts 1 (letter 'C'), 2 ('aug' or '+'), and 3 (digit '7'). These indicate a chord formed by the notes C–E–G–B. The three parts of the symbol (C, aug, and 7) refer to the root C, the augmented (fif ...
