In 1812, Mohs became professor in Graz, Austria. In 1817, Mohs replaced his mentor Werner, who had died, as a tutor at the mining academy in Freiberg, Saxony, starting in 1818. In 1826, he was appointed as a professor of Mineralogy at the University of Vienna.
Mohs ended his remarkable career as a mining advisor at the Mining University in Leoban, Austria, and died aged 66, while holidaying in Italy.
Chelicerata
The Chelicerata are a sub-phylum of the Arthropods. The sub-phylum consists of only two classes: the Arachnids and the Merostomata.
The Merostomata are the extinct Eurypterids and the horseshoe crabs (Xiphosura). The horseshoe crabs are a small, ancient group which has survived relatively unchanged for millions of years. Groups like this are often called living fossils. The Arachnida is the huge and successful terrestrial (air-breathing) group of spiders and their relatives.
The chelicerates originated as marine animals. The first confirmed chelicerate fossils, the eurypterids, date from 445 million years ago in the late Ordovician period. Although only four marine species survive, all of them horseshoe crabs, there are over 77,000 species of air-breathing chelicerates, and there may be about 500,000 unidentified species.
The pycnogonids may or may not be Chelicerates. This is in dispute, as genetic evidence suggests they may be an ancient sister group to all other living arthropods. There are 1,300 species of these 'sea spiders'.
The life-style of chelicerates is largely carnivorous, or other kinds of heterotroph.
Cameraman
A cameraman or camera operator, is the person who takes motion pictures of the actors in a movie with a motion picture camera. They also are the people who work the cameras for television shows and news.
Wire-crested Thorntail
The wire-crested thorntail ("Discosura popelairii") is a species of hummingbird. It lives in Colombia, Ecuador and Peru. Their coloring is steel-blue, with white shafts, making a pretty sight when spread. The bird has a crest of bright green feathers. These birds feed on nectar from flowers using their long tongue or catch insects on the wing.
Avoidant personality disorder
Avoidant personality disorder (AvPD) is a type of personality disorder, a long-term mental illness.
People diagnosed with avoidant personality disorder are socially inhibited, meaning that they are shy and afraid of social situations. They feel that they are not good people and are afraid of people rejecting them. They are very sensitive to other people saying bad or negative things about them.
Psychiatrists and other mental health professionals diagnose people with AvPD using a book called the "Diagnostic and Statistical Manual of Mental Disorders" (DSM-IV-TR). They look at a person's behaviour and how they are feeling. If the person has four or more of the following signs, the DSM-IV-TR says that they have AvPD.
The symptoms of AvPD are much more serious than ordinary shyness.
Cassiopeia (mythology)
Cassiopeia was a woman in Macedonian mythology. She was the wife of Cepheus who was king of Ethiopia. They had a daughter called Andromeda. Cassiopeia was very beautiful but also very arrogant and vain. She thought that she was better than other people. One day, Cassiopeia said that her daughter Andromeda was more beautiful than all of the Nereids. The Nereids were sea-nymphs. When the sea-god Poseidon heard what Cassiopeia had said, he was very angry. He sent floods and a sea monster called Cetus to destroy Ethiopia. Cassiopeia and her husband Cepheus asked an oracle what to do. The oracle said that they must sacrifice their daughter so they chained Andromeda to a rock. A hero named Perseus came and rescued Andromeda. Later, they got married.
Poseidon was still angry with Cassiopeia and wanted to punish her. He placed her in the sky. There is a constellation called Cassiopeia named after her.
Cassiopeia
Cassiopeia (or Kassiopeia) can mean:
Branch line
A branch line is a secondary railway line. It links to a more important route, usually a main line. A very short branch line may be called a spur line. David Blyth Hanna, the first president of the Canadian National Railway, said that although most branch lines cannot pay for themselves, they are essential to make main lines pay.
Atlantic Records
Atlantic Records (Atlantic Recording Corporation) is a major record label. It sold rhythm & blues, rock and roll, and jazz. It was founded in October 1947 by Ahmet Ertegün and Herb Abramson. Some of its groups included Cream, Led Zeppelin, Yes, and Foreigner.
Amazilia hummingbird
The amazilia hummingbird ("Amazilia amazilia") is a species of hummingbird. The loja hummingbird ("A. alticola") has less tan-brown underparts. It is sometimes thought to be a subspecies of the amazilia hummingbird.
The amazilia hummingbird lives in western Peru and Ecuador. It is mostly common, and can be seen in big cities such as Lima and Guayaquil. It likes dry, open or partly-open habitats, but also lives in forests.
Wikimedia Foundation
The Wikimedia Foundation is a non-profit foundation. Their main headquarters is in San Francisco in the United States. The Wikimedia Foundation runs many projects using the wiki idea and the MediaWiki software. These projects include Wikipedia, Wiktionary, Wikiquote, Wikisource, Wikinews, Wikibooks, Wikiversity, Wikimedia Commons, Wikidata, Wikivoyage, and Meta-Wiki.
There are many other wikis related to the foundation, but these are mostly smaller projects. They include the Wikimedia Foundation wiki, the MediaWiki wiki, the Test Wikipedia, the Wikimedia , Bugzilla, and the Wikimania wiki.
The foundation's creation was officially announced by Wikipedia co-founder Jimmy Wales, who was running Wikipedia within his company Bomis, on June 20, 2003.
The foundation gets most of its funds from , as it is nonprofit. It also looks for grants. Some companies have helped Wikimedia by giving free computer hardware, and by hosting servers. Since people can write the wikis, Wikimedia projects are free to use. Funds are used to run computer servers and to pay staff. The Foundation had 160 employees in 2013.
In 2013, Sue Gardner was the executive director.
In 2015, Patricio Lorente was the Chair of the Wikimedia Foundation Board.
In 2016, Katherine Maher became the executive director.
In 2018, María Sefidari is chair of the board.
The Board of Trustees in charge of all the affairs of the Foundation has ten members:
The Signpost reported that two new trustees were elected in 2019:
The Foundation also has an , an international network of experts who have agreed to give the foundation meaningful help on a regular basis in many different areas, including law, organizational development, technology, policy, and outreach.
David Chalmers
David Chalmers was born in 1966. He has lived in Australia all of his life.
Since 2004 he has been a professor of philosophy at the Australian National University.
He has challenged other philosophers to solve the "Hard Problem of consciousness". This is the problem of explaining the relationship between physical and mental states. For example, the brain has a physical way of processing information and this makes an experience, a mental state.
Australian giant cuttlefish
The Australian giant cuttlefish ("Sepia apama") is the biggest species of cuttlefish.
It grows up to in mantle length length and over pounds in weight. Australian Giant Cuttlefish live in the southern coast of Australia, from Brisbane in Queensland to Shark Bay in Western Australia. It lives in rocky reefs, seagrass beds, and sand or mud seafloor to a depth of 100 meters. Indo-Pacific bottlenose dolphins have been seen to eat them.
