Venus is the second planet from the Sun. It is named after the Roman goddess of love and beauty. As the brightest natural object in Earth's night sky after the Moon, Venus can cast shadows and can be, on rare occasions, visible to the naked eye in broad daylight. Venus lies within Earth's orbit, and so never appears to venture far from the Sun, either setting in the west just after dusk or rising in the east a little while before dawn. Venus orbits the Sun every 224.7 Earth days. With a rotation period of 243 Earth days, it takes longer to rotate about its axis than any other planet in the Solar System by far, and does so in the opposite direction to all but Uranus (meaning the Sun rises in the west and sets in the east). Venus does not have any moons, a distinction it shares only with Mercury among the planets in the Solar System.Venus is a terrestrial planet and is sometimes called Earth's "sister planet" because of their similar size, mass, proximity to the Sun, and bulk composition. It is radically different from Earth in other respects. It has the densest atmosphere of the four terrestrial planets, consisting of more than 96% carbon dioxide. The atmospheric pressure at the planet's surface is about 92 times the sea level pressure of Earth, or roughly the pressure at 900 m (3,000 ft) underwater on Earth.

Jellyfish and sea jellies are the informal common names given to the medusa-phase of certain gelatinous members of the subphylum Medusozoa, a major part of the phylum Cnidaria. Jellyfish are mainly free-swimming marine animals with umbrella-shaped bells and trailing tentacles, although a few are anchored to the seabed by stalks rather than being mobile. The bell can pulsate to provide propulsion for highly efficient locomotion. The tentacles are armed with stinging cells and may be used to capture prey and defend against predators. Jellyfish have a complex life cycle; the medusa is normally the sexual phase, which produces planula larva that disperse widely and enter a sedentary polyp phase before reaching sexual maturity.
Jellyfish are found all over the world, from surface waters to the deep sea. Scyphozoans (the "true jellyfish") are exclusively marine, but some hydrozoans with a similar appearance live in freshwater. Large, often colorful, jellyfish are common in coastal zones worldwide. The medusae of most species are fast-growing, and mature within a few months then die soon after breeding, but the polyp stage, attached to the seabed, may be much more long-lived. Jellyfish have been in existence for at least 500 million years, and possibly 700 million years or more, making them the oldest multi-organ animal group.Jellyfish are eaten by humans in certain cultures.

The symbol # is known as the number sign, hash, or, in North American usage, pound sign. The symbol has historically been used for a wide range of purposes including the designation of an ordinal number and as a ligatured abbreviation for pounds avoirdupois – having been derived from the now-rare ℔.Since 2007, widespread usage of the symbol to introduce metadata tags on social media platforms has led to such tags being known as "hashtags", and from that, the symbol itself is sometimes called a hashtag.The symbol is distinguished from similar symbols by its combination of level horizontal strokes and right-tilting vertical strokes.


== History ==

It is believed that the symbol traces its origins to the symbol ℔, an abbreviation of the Roman term libra pondo, which translates as "pound weight". This abbreviation was printed with a dedicated ligature type, with a horizontal line across, so that the lowercase letter l would not be mistaken for the numeral 1. Ultimately, the symbol was reduced for clarity as an overlay of two horizontal strokes "=" across two slash-like strokes "//". Examples of it being used to indicate pounds exist at least as far back as 1850.The symbol is described as the "number" character in an 1853 treatise on bookkeeping, and its double meaning is described in a bookkeeping text from 1880. The instruction manual of the Blickensderfer model 5 typewriter (c. 1896) appears to refer to the symbol as the "number mark". Some early-20th-century U.S. sources refer to it as the "number sign", although this could also refer to the numero sign. A 1917 manual distinguishes between two uses of the sign: "number (written before a figure)"; and "pounds (written after a figure)". The use of the phrase "pound sign" to refer to this symbol is found from 1932 in U.S. usage.

The Space Shuttle was a partially reusable low Earth orbital spacecraft system operated from 1981 to 2011 by the U.S. National Aeronautics and Space Administration (NASA) as part of the Space Shuttle program. Its official program name was Space Transportation System (STS), taken from a 1969 plan for a system of reusable spacecraft where it was the only item funded for development. The first of four orbital test flights occurred in 1981, leading to operational flights beginning in 1982. Five complete Space Shuttle orbiter vehicles were built and flown on a total of 135 missions from 1981 to 2011, launched from the Kennedy Space Center (KSC) in Florida. Operational missions launched numerous satellites, interplanetary probes, and the Hubble Space Telescope (HST), conducted science experiments in orbit, participated in the Shuttle-Mir program with Russia, and participated in construction and servicing of the International Space Station (ISS). The Space Shuttle fleet's total mission time was 1,322 days, 19 hours, 21 minutes and 23 seconds.Space Shuttle components include the Orbiter Vehicle (OV) with three clustered Rocketdyne RS-25 main engines, a pair of recoverable solid rocket boosters (SRBs), and the expendable external tank (ET) containing liquid hydrogen and liquid oxygen. The Space Shuttle was launched vertically, like a conventional rocket, with the two SRBs operating in parallel with the orbiter's three main engines, which were fueled from the ET. The SRBs were jettisoned before the vehicle reached orbit, and the ET was jettisoned just before orbit insertion, which used the orbiter's two Orbital Maneuvering System (OMS) engines. At the conclusion of the mission, the orbiter fired its OMS to deorbit and reenter the atmosphere. The orbiter was protected during reentry by its thermal protection system tiles, and it glided as a spaceplane to a runway landing, usually to the Shuttle Landing Facility at KSC, Florida, or to Rogers Dry Lake in Edwards Air Force Base, California. If the landing occurred at Edwards, the orbiter was flown back to the KSC on the Shuttle Carrier Aircraft, a specially modified Boeing 747.

Curling is a sport in which players slide stones on a sheet of ice toward a target area which is segmented into four concentric circles. It is related to bowls, boules and shuffleboard. Two teams, each with four players, take turns sliding heavy, polished granite rocks, also called stones, across the ice curling sheet toward the house, a circular target marked on the ice. Each team has eight stones, with each player throwing two. The purpose is to accumulate the highest score for a game; points are scored for the stones resting closest to the centre of the house at the conclusion of each end, which is completed when both teams have thrown all of their stones. A game usually consists of eight or ten ends.
The player can induce a curved path, described as curl, by causing the stone to slowly turn as it slides. The path of the rock may be further influenced by two sweepers with brooms or brushes, who accompany it as it slides down the sheet and sweep the ice in front of the stone. "Sweeping a rock" decreases the friction, which makes the stone travel a straighter path (with less "curl") and a longer distance. A great deal of strategy and teamwork go into choosing the ideal path and placement of a stone for each situation, and the skills of the curlers determine the degree to which the stone will achieve the desired result.

Play-Doh is a modeling compound used by young children for arts and crafts projects at home. The product was first manufactured in Cincinnati, Ohio, United States, as a wallpaper cleaner in the 1930s. Play-Doh was then reworked and marketed to Cincinnati schools in the mid-1950s. Play-Doh was demonstrated at an educational convention in 1956 and prominent department stores opened retail accounts.  Advertisements promoting Play-Doh on influential children's television shows in 1957 furthered the product's sales. Since its launch on the toy market in the mid-1950s, Play-Doh has generated a considerable amount of ancillary merchandise such as the Fun Factory.


== History ==


=== Origin ===

The non-toxic, non-staining, reusable modeling compound that came to be known as "Play-Doh" was a pliable, putty-like substance concocted by Noah McVicker of Cincinnati-based soap manufacturer Kutol Products. It was devised at the request of Kroger Grocery, which wanted a product that could clean coal residue from wallpaper.  Following World War II, with the transition from coal-based home heating to natural gas and the resulting decrease in internal soot, and the introduction of washable vinyl-based wallpaper, the market for wallpaper cleaning putty decreased substantially. McVicker's nephew, Joe McVicker, joined Kutol with the remit to save the company from bankruptcy.

The Chicago Cubs are an American professional baseball team based in Chicago. The Cubs compete in Major League Baseball (MLB) as a member club of the National League (NL) Central division. The team plays its home games at Wrigley Field, located on the city's North Side. The Cubs are one of two major league teams based in Chicago; the other, the Chicago White Sox, is a member of the American League (AL) Central division. The Cubs, first known as the White Stockings, were a founding member of the NL in 1876, becoming the Chicago Cubs in 1903.Throughout the club's history, the Cubs have played in a total of eleven World Series.  The 1906 Cubs won 116 games, finishing 116–36 and posting a modern-era record winning percentage of .763, before losing the World Series to the Chicago White Sox ("The Hitless Wonders") by four games to two. The Cubs won back-to-back World Series championships in 1907 and 1908, becoming the first major league team to play in three consecutive World Series, and the first to win it twice.  Most recently, the Cubs won the 2016 National League Championship Series and 2016 World Series, which ended a 71-year National League pennant drought and a 108-year World Series championship drought, both of which are record droughts in Major League Baseball. The 108-year drought was also the longest such occurrence in all major North American sports. Since the start of divisional play in 1969, the Cubs have appeared in the postseason ten times through the 2019 season.The Cubs are known as "the North Siders", a reference to the location of Wrigley Field within the city of Chicago, and in contrast to the White Sox, whose home field (Guaranteed Rate Field) is located on the South Side.

Xmas (also X-mas) is a common abbreviation of the word Christmas. It is sometimes pronounced , but Xmas, and variants such as Xtemass, originated as handwriting abbreviations for the typical pronunciation . The "X" comes from the Greek letter Chi, which is the first letter of the Greek word Christós (Greek: Χριστός), which became Christ in English.
The suffix -mas is from the Latin-derived Old English word for Mass.There is a common misconception that the word Xmas stems from a secular attempt to remove the religious tradition from Christmas by taking the "Christ" out of "Christmas", but its use dates back to the 16th century.


== Style guides and etiquette ==
"Xmas" is deprecated by some modern style guides, including those at the New York Times, The Times, The Guardian, and the BBC. Millicent Fenwick, in the 1948 Vogue's Book of Etiquette, states that "'Xmas' should never be used" in greeting cards. The Cambridge Guide to Australian English Usage states that the spelling should be considered informal and restricted to contexts where concision is valued, such as headlines and greeting cards. The Christian Writer's Manual of Style, while acknowledging the ancient and respectful use of "Xmas" in the past, states that the spelling should never be used in formal writing.


== History ==


=== Use in English ===

Early use of "Xmas" includes Bernard Ward's History of St. Edmund's college, Old Hall (originally published circa 1755). An earlier version, "X'temmas", dates to 1551.

The United States of America (U.S.A. or USA), commonly known as the United States (U.S. or US) or America, is a country primarily located in North America. It consists of 50 states, a federal district, five major unincorporated territories, 326 Indian reservations, and some minor possessions. At 3.8 million square miles (9.8 million square kilometers), it is the world's third- or fourth-largest country by total area. It borders Canada to the north and Mexico to the south. With a population of more than 331 million people, it is the third most populous country in the world. The national capital is Washington, D.C., and the most populous city is New York City.
Paleo-Indians migrated from Siberia to the North American mainland at least 12,000 years ago, and European colonization began in the 16th century. The United States emerged from the thirteen British colonies established along the East Coast. Disputes over taxation and political representation with Great Britain led to the American Revolutionary War (1775–1783), which established independence. In the late 18th century, the U.S. began expanding across North America, gradually obtaining new territories, sometimes through war, frequently displacing Native Americans, and admitting new states; by 1848, the United States spanned the continent.

Paul Jackson Pollock  (January 28, 1912 – August 11, 1956) was an American painter and a major figure in the abstract expressionist movement.
He was widely noticed for his technique of pouring or splashing liquid household paint onto a horizontal surface ("drip technique"), enabling him to view and paint his canvases from all angles. It was also called all-over painting and "action painting", since he covered the entire canvas and used the force of his whole body to paint, often in a frenetic dancing style. This extreme form of abstraction divided the critics: some praised the immediacy of the creation, while others derided the random effects. In 2016, Pollock's painting titled Number 17A was reported to have fetched US$200 million in a private purchase.
A reclusive and volatile personality, Pollock struggled with alcoholism for most of his life. In 1945, he married the artist Lee Krasner, who became an important influence on his career and on his legacy. Pollock died at the age of 44 in an alcohol-related single-car accident when he was driving. In December 1956, four months after his death, Pollock was given a memorial retrospective exhibition at the Museum of Modern Art (MoMA) in New York City. A larger, more comprehensive exhibition of his work was held there in 1967.

The colossal squid (Mesonychoteuthis hamiltoni) is part of the family Cranchiidae. It is sometimes called the Antarctic squid or giant cranch squid and is believed to be the largest squid species in terms of mass. It is the only recognized member of the genus Mesonychoteuthis and is known from only a small number of specimens. The species is confirmed to reach a mass of at least 495 kilograms (1,091 lb), though the largest specimens—known only from beaks found in sperm whale stomachs—may perhaps weigh as much as 600–700 kilograms (1,300–1,500 lb), making it the largest-known invertebrate. Maximum total length has been estimated at 9–10 metres (30–33 ft).This species shares anatomy similar to other members of its family although it is the only member of Cranchiidae to display hooks on its arms and tentacles. It is known to inhabit the circumantarctic Southern Ocean. Although little is known about the behavior, it is known to use bioluminescence to attract prey. Additionally, it is presumed to be an ambush predator, and is a major prey of the sperm whale.The first specimens were discovered and described in 1925. In 1981, an adult specimen was discovered, and in 2003 a second specimen was collected. Captured in 2007, the largest live colossal squid weighed 495 kilograms (1,091 lb), and is now on display with a second specimen at the Museum of New Zealand Te Papa Tongarewa.
