Light is electromagnetic radiation within a certain portion of the electromagnetic spectrum. The word usually refers to visible light, which is visible to the human eye and is responsible for the sense of sight. Visible light is usually defined as having wavelengths in the range of 400–700 nanometres (nm), or 4.00 × 10−7 to 7.00 × 10−7 m, between the infrared (with longer wavelengths) and the ultraviolet (with shorter wavelengths). This wavelength means a frequency range of roughly 430–750 terahertz (THz).
The main source of light on Earth is the Sun. Sunlight provides the energy that green plants use to create sugars mostly in the form of starches, which release energy into the living things that digest them. This process of photosynthesis provides virtually all the energy used by living things. Historically, another important source of light for humans has been fire, from ancient campfires to modern kerosene lamps. With the development of electric lights and power systems, electric lighting has effectively replaced firelight. Some species of animals generate their own light, a process called bioluminescence. For example, fireflies use light to locate mates, and vampire squids use it to hide themselves from prey.
Light Yagami (Japanese: 夜神 月, Hepburn: Yagami Raito) is a fictional character and the protagonist of the manga series Death Note, created by Tsugumi Ohba and Takeshi Obata. He is a bored young genius who finds the Death Note dropped by the Shinigami Ryuk by pure chance. Using the notebook, which allows its owner to kill anyone simply by knowing their name and face, Light becomes a mass-murderer known as Kira (キラ) in an attempt to create and rule a utopia cleansed of criminals, with him at the helm as a "god".
In the anime adaptation, he is voiced by Mamoru Miyano in the Japanese version and by Brad Swaile in the English; in the live-action film series, he is portrayed by Tatsuya Fujiwara, in the TV drama, he is portrayed by Masataka Kubota and, in the American film, he will be portrayed by Nat Wolff.
Tsugumi Ohba, the story writer of Death Note, said that his editor suggested the family name "Yagami" for Light. Ohba said that he did not feel "too concerned" about the meaning of the name (the Kanji for "Yagami" are "night" and "god"); he said that after he created the final scene in the manga he "liked" that the final scene created "deeper significance" in the name, of Kira worshippers worshipping him at night under the light of the moon.
Light is a science fiction novel by M. John Harrison published in 2002. It received the James Tiptree, Jr. Award and a BSFA nomination in 2002, and was shortlisted for the Arthur C. Clarke Award in 2003.
The book centres on the lives of three individuals — the physicist (and serial killer) Michael Kearney, on the verge of a breakthrough in theoretical physics sometime in 1999; Seria Mau Genlicher, the cybernetically-altered female pilot of a "K-ship", and the ex-space pilot and adventurer Ed Chianese. Seria Mau and Ed's stories take place in the year 2400 AD.
The lives of these three individuals are linked in many ways, though most tangibly by the presence of a mysterious creature called The Shrander, who appears in many guises to all three characters throughout the novel (with anagrammatic names of Sandra Shen and Dr. Haends). They are also linked by the Kefahuchi Tract, a space-time anomaly described as "a singularity without an event horizon", an object of awe and wonder that has been the ruin of many civilisations attempting to decode its mysteries.
In economics, supply is the amount of something that firms, consumers, laborers, providers of financial assets, or other economic agents are willing to provide to the marketplace. Supply is often plotted graphically with the quantity provided (the dependent variable) plotted horizontally and the price (the independent variable) plotted vertically.
In the goods market, supply is the amount of a product per unit of time that producers are willing to sell at various given prices when all other factors are held constant. In the labor market, the supply of labor is the amount of time per week, month, or year that individuals are willing to spend working, as a function of the wage rate. In the financial markets, the money supply is the amount of highly liquid assets available in the money market, which is either determined or influenced by a country's monetary authority.
The remainder of this article focuses on the supply of goods.
A supply schedule is a table which shows how much one or more firms will be willing to supply at particular prices under the existing circumstances. Some of the more important factors affecting supply are the good's own price, the prices of related goods, production costs, technology and expectations of sellers.
StarCraft is a military science fiction media franchise created by Chris Metzen and James Phinney, and owned by Blizzard Entertainment. The series centers on a galactic struggle for dominance between four species—the adaptable and mobile Terrans, the ever-evolving insectoid Zerg, the powerfully enigmatic Protoss, and the "god-like" Xel'Naga creator race—in a distant part of the Milky Way galaxy known as the Koprulu Sector at the beginning of the 26th century. The series debuted with the video game StarCraft in 1998. Since then it has grown to include a number of other games as well as eight novelizations, two Amazing Stories articles, a board game, and other licensed merchandise such as collectible statues and toys.
Blizzard Entertainment began planning StarCraft in 1995, with a development team led by Metzen and Phinney. The game debuted at E3 1996, and uses a modified Warcraft II game engine. StarCraft also marked the creation of Blizzard Entertainment's film department; the game introduced high quality cinematics integral to the storyline of the series. Most of the original development team for StarCraft returned to work on the game's official expansion pack, Brood War; the game's development began shortly after StarCraft was released. In 2001, StarCraft: Ghost began development under Nihilistic Software. Unlike the previous real-time strategy games in the series, Ghost was to be a stealth-action game. After three years of development, work on the game was postponed in 2004. Development of StarCraft II: Wings of Liberty began in 2003; the game was later announced on May 19, 2007 and was released on July 27, 2010. The StarCraft II franchise continued with the StarCraft II: Heart of the Swarm expansion, which was released on March 12, 2013. The third StarCraft II installment is titled StarCraft II: Legacy of the Void, released on November 10, 2015.
Basra, also written Basrah (Arabic: البصرة; BGN: Al Başrah), is an Iraqi city located on the Shatt al-Arab river between Kuwait and Iran. It had an estimated population of 1.5 million of 2012. Basra is also Iraq's main port, although it does not have deep water access, which is handled at the port of Umm Qasr.
The city is part of the historic location of Sumer, one of the ports from which Sinbad the Sailor journeyed, and a proposed location of the Garden of Eden. It played an important role in early Islamic history and was built in 636 AD or 14 AH. It is Iraq's second largest and most populous city after Baghdad (Mosul has an uncertain population under ISIS occupation). Basra is consistently one of the hottest cities in Iraq, with summer temperatures regularly exceeding 50 °C (122 °F).
The city was called by many names throughout its history, Basrah being the most common. In Arabic the word basrah means 'the overwatcher', which might have been an allusion to the city's origin as an Arab military base against the Sassanids. Some sources claim that the name is derived from the Persian word Bas-rah, which means "where many paths meet". Others have argued that the name is derived from the Aramaic word basratha, meaning 'place of huts' or 'settlement'.
