One is a pronoun in the English language. It is a gender-neutral, indefinite pronoun, meaning roughly "a person". For purposes of verb agreement it is a third-person singular pronoun, although it is sometimes used with first- or second-person reference. It is sometimes called an impersonal pronoun. It is more or less equivalent to the Scots 'a body', the French pronoun on, the German/Scandinavian man, and the Spanish uno. It has the possessive form one's and the reflexive form oneself.
The pronoun one has quite formal connotations (particularly in American English[1]), and is often avoided in favor of more colloquial alternatives such as generic you.
The word one as a numeral can also be put to use as a pronoun, as in one was clean and the other was dirty, and it can also be used as a prop-word, forming pronominal phrases with other determiners, as in the one, this one, my one, etc. This article, however, concerns the use of one as an indefinite pronoun as described in the preceding paragraphs.

A computer keyboard is a typewriter-style device[1] which uses an arrangement of buttons or keys to act as mechanical levers or electronic switches. Following the decline of punch cards and paper tape, interaction via teleprinter-style keyboards became the main input method for computers.
Keyboard keys (buttons) typically have characters engraved or printed on them,[2][better source needed] and each press of a key typically corresponds to a single written symbol. However, producing some symbols may require pressing and holding several keys simultaneously or in sequence.[3] While most keyboard keys produce letters, numbers or signs (characters), other keys or simultaneous key presses can produce actions or execute computer commands.
In normal usage, the keyboard is used as a text entry interface for typing text and numbers into a word processor, text editor or any other program. In a modern computer, the interpretation of key presses is generally left to the software. A computer keyboard distinguishes each physical key from every other key and reports all key presses to the controlling software. Keyboards are also used for computer gaming — either regular keyboards or keyboards with special gaming features, which can expedite frequently used keystroke combinations.
A keyboard is also used to give commands to the operating system of a computer, such as Windows' Control-Alt-Delete combination. Although on Pre-Windows 95 Microsoft operating systems this forced a re-boot, now it brings up a system security options screen.[4][5]
A command-line interface is a type of user interface navigated entirely using a keyboard, or some other similar device that does the job of one.
A laptop computer (also shortened to just laptop; or called a notebook computer) is a small, portable personal computer (PC) with a "clamshell" form factor, typically having a thin LCD or LED computer screen mounted on the inside of the upper lid of the clamshell and an alphanumeric keyboard on the inside of the lower lid. The clamshell is opened up to use the computer. Laptops are folded shut for transportation, and thus are suitable for mobile use.[1] Its name comes from lap, as it was deemed to be placed on a person's lap when being used. Although originally there was a distinction between laptops and notebooks (the former being bigger and heavier than the latter), as of 2014, there is often no longer any difference.[2] Laptops are commonly used in a variety of settings, such as at work, in education, for playing games, Internet surfing, for personal multimedia, and general home computer use.
Laptops combine all the input/output components and capabilities of a desktop computer, including the display screen, small speakers, a keyboard, hard disk drive, optical disc drive, pointing devices (such as a touchpad or trackpad), a processor, and memory into a single unit. Most modern laptops feature integrated webcams and built-in microphones, while many also have touchscreens. Laptops can be powered either from an internal battery or by an external power supply from an AC adapter. Hardware specifications, such as the processor speed and memory capacity, significantly vary between different types, makes, models and price points.
Design elements, form factor and construction can also vary significantly between models depending on intended use. Examples of specialized models of laptops include rugged notebooks for use in construction or military applications, as well as low production cost laptops such as those from the One Laptop per Child (OLPC) organization, which incorporate features like solar charging and semi-flexible components not found on most laptop computers. Portable computers, which later developed into modern laptops, were originally considered to be a small niche market, mostly for specialized field applications, such as in the military, for accountants, or for traveling sales representatives. As the portable computers evolved into the modern laptop, they became widely used for a variety of purposes.[3]

Leleuvia (pronounced [leleuˈβia]) is a coral cay in Fiji's Lomaiviti archipelago. The 68,000 square metres (731,946 sq ft) islet is the site of the Leleuvia Island Resort, previously operated by the Chinese-Fijian businessman Emosi Yee Shaw. Only recently in early 2006 has the Island been leased by a Company called Saluwaki Limited with the intention to refurbish the island resort. Leleuvia Island is popular among beachcombers and kite surfers.
There is snorkelling directly off the beach. Many travellers have come for three days and ended up staying three weeks or longer.

Venice (/ˈvɛnɪs/ VEN-iss; Italian: Venezia [veˈnɛttsja] (About this soundlisten); Venetian: Venesia or Venexia, pronounced [veˈnɛsja]) is a city in northeastern Italy and the capital of the Veneto region. It is situated on a group of 118 small islands[3] that are separated by canals and linked by over 400 bridges.[3][4] The islands are located in the shallow Venetian Lagoon, an enclosed bay that lies between the mouths of the Po and the Piave rivers (more exactly between the Brenta and the Sile). In 2018, 260,897 people resided in the Comune di Venezia, of whom around 55,000 live in the historical city of Venice (centro storico). Together with Padua and Treviso, the city is included in the Padua-Treviso-Venice Metropolitan Area (PATREVE), which is considered a statistical metropolitan area, with a total population of 2.6 million.[5]
The name is derived from the ancient Veneti people who inhabited the region by the 10th century BC.[6][7] The city was historically the capital of the Republic of Venice for a millennium and more, from 697 to 1797. It was a major financial and maritime power during the Middle Ages and Renaissance, and a staging area for the Crusades and the Battle of Lepanto, as well as an important center of commerce—especially silk, grain, and spice, and of art from the 13th century to the end of the 17th. The city-state of Venice is considered to have been the first real international financial center, emerging in the 9th century and reaching its greatest prominence in the 14th century.[8] This made Venice a wealthy city throughout most of its history.[9] After the Napoleonic Wars and the Congress of Vienna, the Republic was annexed by the Austrian Empire, until it became part of the Kingdom of Italy in 1866, following a referendum held as a result of the Third Italian War of Independence.
Venice has been known as "La Dominante", "La Serenissima", "Queen of the Adriatic", "City of Water", "City of Masks", "City of Bridges", "The Floating City", and "City of Canals". The lagoon and a part of the city are listed as a UNESCO World Heritage Site. Parts of Venice are renowned for the beauty of their settings, their architecture, and artwork.[3] Venice is known for several important artistic movements—especially during the Renaissance period—has played an important role in the history of symphonic and operatic music, and is the birthplace of Antonio Vivaldi.[10]
Although the city is facing some challenges (including an excessive number of tourists and problems caused by pollution, tide peaks and cruise ships sailing close to the buildings),[11][12][13] Venice remains a very popular tourist destination, a major cultural centre, and has been ranked many times the most beautiful city in the world.[14][15] It has been described by the Times Online as one of Europe's most romantic cities[16] and by The New York Times as "undoubtedly the most beautiful city built by man".[17]
3MM-1 is a star-forming galaxy from about 12.5 billion light-years away that is obscured by clouds of dust.[1] It was first detected in spectroscopic data on rotational transitions of carbon monoxide obtained using the Atacama Large Millimeter Array from 23-24 December 2018, as detailed in an article that was published on 22 October 2019. The authors of this article described the discovery as "serendipitous",[2] since 3MM-1 was found at a redshift of about 5.5, while the focus of their planned observations had been on galaxies at redshifts near 1.5 that are quiescent, i.e. do not form stars, and directly observable.[2][3] In the same dataset, another dust-obscured star-forming galaxy, 3MM-2, was found at a redshift of about 3.3.[2]
3MM-1 has a mass of about 1010.8 solar masses, and stars form in it at about 100 times the rate as in the Milky Way.[1]

The Milky Way[a] is the galaxy that contains our Solar System, with the name describing the galaxy's appearance from Earth: a hazy band of light seen in the night sky formed from stars that cannot be individually distinguished by the naked eye. The term Milky Way is a translation of the Latin via lactea, from the Greek γαλαξίας κύκλος (galaxías kýklos, "milky circle").[17][18][19] From Earth, the Milky Way appears as a band because its disk-shaped structure is viewed from within. Galileo Galilei first resolved the band of light into individual stars with his telescope in 1610. Until the early 1920s, most astronomers thought that the Milky Way contained all the stars in the Universe.[20] Following the 1920 Great Debate between the astronomers Harlow Shapley and Heber Curtis,[21] observations by Edwin Hubble showed that the Milky Way is just one of many galaxies.
The Milky Way is a barred spiral galaxy with a diameter between 150,000 and 200,000 light-years (ly).[22][23][24][25] It is estimated to contain 100–400 billion stars[26][27] and more than 100 billion planets.[28][29] The Solar System is located at a radius of about 27,000 light-years from the Galactic Center [13], on the inner edge of the Orion Arm, one of the spiral-shaped concentrations of gas and dust. The stars in the innermost 10,000 light-years form a bulge and one or more bars that radiate from the bulge. The galactic center is an intense radio source known as Sagittarius A*, assumed to be a supermassive black hole of 4.100 (± 0.034) million solar masses.
Stars and gases at a wide range of distances from the Galactic Center orbit at approximately 220 kilometers per second. The constant rotation speed contradicts the laws of Keplerian dynamics and suggests that much (about 90%)[30][31] of the mass of the Milky Way is invisible to telescopes, neither emitting nor absorbing electromagnetic radiation. This conjectural mass has been termed "dark matter".[32] The rotational period is about 240 million years at the radius of the Sun.[14] The Milky Way as a whole is moving at a velocity of approximately 600 km per second with respect to extragalactic frames of reference. The oldest stars in the Milky Way are nearly as old as the Universe itself and thus probably formed shortly after the Dark Ages of the Big Bang.[33]
The Milky Way has several satellite galaxies and is part of the Local Group of galaxies, which form part of the Virgo Supercluster, which is itself a component of the Laniakea Supercluster.[34][35]
The Sylvester Medal is a bronze medal awarded by the Royal Society (London) for the encouragement of mathematical research, and accompanied by a £1,000 prize.[1] It was named in honour of James Joseph Sylvester, the Savilian Professor of Geometry at the University of Oxford in the 1880s, and first awarded in 1901, having been suggested by a group of Sylvester's friends (primarily Raphael Meldola) after his death in 1897.[2][3] Initially awarded every three years with a prize of around £900,[2][4] the Royal Society have announced that starting in 2009 it will be awarded every two years instead, and is to be aimed at 'early to mid career stage scientist' rather than an established mathematician.[1] The award winner is chosen by the Society's A-side awards committee, which handles physical rather than biological science awards.
As of 2019, 43 medals have been awarded, of which all but 10 have been awarded to citizens of the United Kingdom, two to citizens of France and United States, and one medal each has been won by citizens of New Zealand, Germany, Austria, Russia, Italy, Sweden and South Africa. Only two women (Mary Cartwright and Dusa McDuff) have ever won the medal.
