Buridan's ass is an illustration of a paradox in philosophy in the conception of free will. It refers to a hypothetical situation wherein an ass that is equally hungry and thirsty is placed precisely midway between a stack of hay and a pail of water. Since the paradox assumes the ass will always go to whichever is closer, it dies of both hunger and thirst since it cannot make any rational decision between the hay and water. A common variant of the paradox substitutes two identical piles of hay for the hay and water; the ass, unable to choose between the two, dies of hunger.

The paradox is named after the 14th-century French philosopher Jean Buridan, whose philosophy of moral determinism it satirizes. Although the illustration is named after Buridan, philosophers have discussed the concept before him, notably Aristotle, who used the example of a man equally hungry and thirsty, and Al-Ghazali, who used a man faced with the choice of equally good dates.

A version of this situation appears as metastability in digital electronics, when a circuit must decide between two states based on an input that is in itself undefined (neither zero nor one). Metastability becomes a problem if the circuit spends more time than it should in this "undecided" state, which is usually set by the speed of the clock the system is using.

🔗 Biography 🔗 Mathematics 🔗 France 🔗 Biography/science and academia

Évariste Galois (; French: [evaʁist ɡalwa]; 25 October 1811 – 31 May 1832) was a French mathematician and political activist. While still in his teens, he was able to determine a necessary and sufficient condition for a polynomial to be solvable by radicals, thereby solving a problem that had been open for 350 years. His work laid the foundations for Galois theory and group theory, two major branches of abstract algebra.

Galois was a staunch republican and was heavily involved in the political turmoil that surrounded the French Revolution of 1830. As a result of his political activism, he was arrested repeatedly, serving one jail sentence of several months. For reasons that remain obscure, shortly after his release from prison, Galois fought in a duel and died of the wounds he suffered.

Qwest Communications International, Inc. was a large United States telecommunications carrier. Qwest provided local service in 14 western and midwestern U.S. states: Arizona, Colorado, Idaho, Iowa, Minnesota, Montana, Nebraska, New Mexico, North Dakota, Oregon, South Dakota, Utah, Washington, and Wyoming.

On April 22, 2010, CenturyLink announced it would acquire Qwest in a stock transaction. The merger closed on April 1, 2011. Qwest began doing business as CenturyLink in August 2011.

Qwest provided voice, Internet backbone data services, and digital television in some areas. It operated in three segments: Wireline Services, Wireless Services, and Other Services. The Wireline Services segment provided local voice, long-distance voice, and data and Internet (DSL) services to consumers, businesses, and wholesale customers, as well as access services to wholesale customers. The Wireless Services segment was achieved by a partnership with Verizon Wireless. Qwest also partnered with DirecTV to provide digital television service to its customers. In Phoenix, Denver, Salt Lake City, Boise, and Omaha, Qwest offered Qwest Choice TV (later also known as Qwest Digital Television), an IPTV service over DSL. This service was retired in October 2008 (after being no longer available to new customers in May 2008), leaving DirecTV as the only TV service Qwest provided. Qwest Choice TV customers were moved to DirecTV. The Other Services segment primarily involved the sublease of real estate assets, such as space in office buildings, warehouses, and other properties.

Qwest Communications also provided long-distance services and broadband data, as well as voice and video communications globally. The company sold its products and services to small businesses, governmental entities, and public and private educational institutions through various channels, including direct-sales marketing, telemarketing, arrangements with third-party agents, company's Web site, and partnership relations. As of September 13, 2005, Qwest had 98 retail stores in 14 states. Qwest Communications was headquartered in Denver, Colorado at 1801 California Street, in the second tallest building in Denver at 53 stories. The majority of Qwest occupational or non-management employees were represented by two labor unions; the Communications Workers of America and in Montana, the International Brotherhood of Electrical Workers. Qwest also had software development centers in Bangalore and Noida (New Delhi), India called Qwest Software Services.

🔗 Computing

The Alternate Instruction Set (AIS) is a second 32-bit instruction set architecture found in some x86 CPUs made by VIA Technologies. On these VIA C3 processors, the second hidden processor mode is accessed by executing the x86 instruction ALTINST (0F 3F). If AIS mode has been enabled, the processor will perform a JMP EAX and begin executing AIS instructions at the address of the EAX register. Using AIS allows native access to the Centaur Technology-designed RISC core inside the processor.

The 2009 flu pandemic in the United States was a novel strain of the Influenza A/H1N1 virus, commonly referred to as "swine flu", that began in the spring of 2009. The virus had spread to the US from an outbreak in Mexico.

The U.S. Centers for Disease Control and Prevention (CDC) estimates that from April 12, 2009 to April 10, 2010, there were 60.8 million cases, 274,000 hospitalizations, and 12,469 deaths (0.02% infection fatality rate/Mortality rate) in the United States due to the virus.

The Toyota Way is a set of principles and behaviors that underlie the Toyota Motor Corporation's managerial approach and production system. Toyota first summed up its philosophy, values and manufacturing ideals in 2001, calling it "The Toyota Way 2001". It consists of principles in two key areas: continuous improvement, and respect for people.

🔗 Oceans

Tide-Predicting Machine No. 2, also known as Old Brass Brains, was a special-purpose mechanical computer that uses gears, pulleys, chains, and other mechanical components to compute the height and time of high and low tides for specific locations. The machine can perform tide calculations much faster than a person could do with pencil and paper. The U.S. Coast and Geodetic Survey put the machine into operation in 1910. It was used until 1965, when it was replaced by an electronic computer.

🔗 Urban studies and planning

Marchetti's constant is the average time spent by a person for commuting each day, which is approximately one hour. It is named after Italian physicist Cesare Marchetti, though Marchetti himself attributed the "one hour" finding to transportation analyst and engineer Yacov Zahavi. Marchetti posits that although forms of urban planning and transport may change, and although some live in villages and others in cities, people gradually adjust their lives to their conditions (including location of their homes relative to their workplace) such that the average travel time stays approximately constant. Ever since Neolithic times, people have kept the average time spent per day for travel the same, even though the distance may increase due to the advancements in the means of transportation. In his 1934 book Technics and Civilization, Lewis Mumford attributes this observation to Bertrand Russell:

Mr. Bertrand Russell has noted that each improvement in locomotion has increased the area over which people are compelled to move: so that a person who would have had to spend half an hour to walk to work a century ago must still spend half an hour to reach his destination, because the contrivance that would have enabled him to save time had he remained in his original situation now—by driving him to a more distant residential area—effectually cancels out the gain.

A related concept is that of Zahavi, who also noticed that people seem to have a constant "travel time budget", that is, "a stable daily amount of time that people make available for travel." David Metz, former chief scientist at the Department of Transport, UK, cites data of average travel time in Britain drawn from the British National Travel Survey in support of Marchetti's and Zahavi's conclusions. The work casts doubt on the contention that investment in infrastructure saves travel time. Instead, it appears from Metz's figures that people invest travel time saved in travelling a longer distance, a particular example of Jevons paradox described by the Lewis–Mogridge position. Because of the constancy of travel times as well as induced travel, Robert Cervero has argued that the World Bank and other international aid agencies evaluate transportation investment proposals in developing and rapidly motorizing cities less on the basis of potential travel-time savings and more on the accessibility benefits they confer.

🔗 Video games 🔗 Computing

Habitat is a massively multiplayer online role-playing game (MMORPG) developed by LucasArts. It is the first attempt at a large-scale commercial virtual community that was graphic based. Initially created in 1985 by Randy Farmer and Chip Morningstar, the game was made available as a beta test in 1986 by Quantum Link, an online service for the Commodore 64 computer and the corporate progenitor to AOL. Both Farmer and Morningstar were given a First Penguin Award at the 2001 Game Developers Choice Awards for their innovative work on Habitat. As a graphical MUD it is considered a forerunner of modern MMORPGs unlike other online communities of the time (i.e. MUDs and massively multiplayer onlines with text-based interfaces). Habitat had a GUI and large user base of consumer-oriented users, and those elements in particular have made Habitat a much-cited project and acknowledged benchmark for the design of today's online communities that incorporate accelerated 3D computer graphics and immersive elements into their environments.
