The term dwarf planet was adopted in 2006 as part of a three-way categorization of bodies orbiting the Sun, brought about by an increase in discoveries of objects farther away from the Sun than Neptune that rivaled Pluto in size, and finally precipitated by the discovery of an even more massive object, Eris. The exclusion of dwarf planets from the roster of planets by the IAU has been both praised and criticized; it was said to be the "right decision" by astronomer Mike Brown, who discovered Eris and other new dwarf planets, but has been rejected by Alan Stern, who had coined the term dwarf planet in 1990.
The International Astronomical Union (IAU) currently recognizes five dwarf planets: Ceres, Pluto, Haumea, Makemake, and Eris. Brown criticizes this official recognition: "A reasonable person might think that this means that there are five known objects in the solar system which fit the IAU definition of dwarf planet, but this reasonable person would be nowhere close to correct."
The concept of the dwarf comes from Norse and Teutonic mythology. In particular, the dwarves in the Germanic story The Ring of the Nibelungen and the Brothers Grimm fairy tale "Rumpelstiltskin" have been called "ancestors" of Dungeons & Dragons dwarves. Along with giants, dwarves were one of the first types of non-humans to be introduced into the Chainmail game, the forebear of D&D, when miniature figures of varying sizes were used together in the same wargame.
There are no written records of the earliest years of the Dwarfs history, though legend states that the first Dwarfs migrated northwards from their southern ancestral homes along the World Edge Mountains, following open veins of ore and tunnelling into the mountains in search of gold, iron and gemstones. As they progressed, many clans built fortified settlements and mines called holds around the richest deposits. Eventually they reached the northern most edge of the mountains - the majority turned back, while some ventured north-west into the lands that would become Norsca and others turned east and crossed the Great Skull Land (these would eventually become the Chaos Dwarves during the Coming of Chaos).
Jimmy Wales and Larry Sanger launched Wikipedia on January 15, 2001. Sanger coined its name, a portmanteau of wiki and encyclopedia. Initially only in English, Wikipedia quickly became multilingual as it developed similar versions in other languages, which differ in content and in editing practices. The English Wikipedia is now one of 291 Wikipedia editions and is the largest with 5,081,662 articles (having reached 5,000,000 articles in November 2015). There is a grand total, including all Wikipedias, of over 38 million articles in over 250 different languages. As of February 2014, it had 18 billion page views and nearly 500 million unique visitors each month.

274301 Wikipedia (provisional designations: 2008 QH24, 2007 FK34, 1997 RO4) is an asteroid orbiting in the asteroid belt. It was discovered by the Andrushivka Astronomical Observatory in August 2008. The asteroid was named after the online encyclopedia Wikipedia in January 2013.
Discovery
The asteroid was discovered by astronomers from the Andrushivka Astronomical Observatory (A50) in Ukraine, the country's only privately owned observatory, which has discovered over 90asteroids since 2003. It was first observed by the Andrushivka team on August 25, 2008, at 22:47 (UTC). It was also observed on the next night and it received provisional designation 2008 QH24. After it was also observed on September 6 by the Andrushivka team, the orbit of the asteroid was calculated accurately. It was shown that the asteroid 2008 QH24 was the same as 1997 RO4 and 2007 FK34 previously spotted by observatories Caussols-ODAS (France), Mt. Lemmon Survey and Steward Observatory (both in Arizona, U.S.). On April 18, 2011, the asteroid received the number 274301. The composition of the asteroid is not known but it is likely to consist, like other asteroids from the asteroid belt, of a mixture of rock and metal.
List was originally a Danish settlement. It was first mentioned in 1292 (Lystum). The original village was destroyed by the great flood of 1364. The settlement was rebuilt further east from the previous location. In the mid-15th century, a church named St. Jürgen was mentioned. In a treaty of 1460, Schleswig and Holstein were linked to the Danish crown, but List remained part of the royal enclaves, small areas of the Kingdom of Denmark situated within the Duchy of Schleswig, but directly controlled by the Danish king.
From the 16th century, the people of List mostly made a living from Oyster farming, raising sheep and collecting and selling gull eggs. At the time, List was an important protective anchorage. In 1644, a Swedish-Dutch fleet of 26 ships commanded by Admiral Thijssen was attacked in the Lister Tief and defeated by Danish ships commanded by king Christian IV of Denmark. The anchorage north of today's town was named Königshafen to honour this event.

Listening is a more natural way of learning, when compared to reading. Written language only began at around 3200 BC, but spoken language has existed long ago.
Learning by listening is a great way to:
- increases imagination and understanding
- improves your listening skills
- improves your own spoken accent
- learn while on the move

SUMMARY
=======
Operation Downfall was the proposed Allied plan for the invasion of Japan near the end of World War II. The planned operation was cancelled when Japan surrendered following the atomic bombings of Hiroshima and Nagasaki, the Soviet declaration of war, and the Soviet invasion of Manchuria. The operation had two parts: Operation Olympic and Operation Coronet. Set to begin in November 1945, Operation Olympic was intended to capture the southern third of the southernmost main Japanese island, Kyūshū, with the recently captured island of Okinawa to be used as a staging area. Later, in the spring of 1946, Operation Coronet was the planned invasion of the Kantō Plain, near Tokyo, on the Japanese island of Honshu. Airbases on Kyūshū captured in Operation Olympic would allow land-based air support for Operation Coronet. If Downfall had taken place, it would have been the largest amphibious operation in history.Japan's geography made this invasion plan quite obvious to the Japanese as well; they were able to accurately predict the Allied invasion plans and thus adjust their defensive plan, Operation Ketsugō, accordingly. The Japanese planned an all-out defense of Kyūshū, with little left in reserve for any subsequent defense operations. Casualty predictions varied widely, but were extremely high. Depending on the degree to which Japanese civilians would have resisted the invasion, estimates ran up into the millions for Allied casualties.
