Emergency telephone number

In many countries the public telephone network has a single emergency telephone number (sometimes known as the universal emergency telephone number or the emergency services number) that allows a caller to contact local emergency services for assistance. The emergency number differs from country to country; it is typically a three-digit number so that it can be easily remembered and dialed quickly. Some countries have a different emergency number for each of the different emergency services; these often differ only by the last digit.

Configuration and operation

The emergency telephone number is a special case in the country's telephone number plan. In the past, calls to the emergency telephone number were often routed over special dedicated circuits. Though with the advent of electronic exchanges these calls are now often mixed with ordinary telephone traffic, they still may be able to access circuits that other traffic cannot. Often the system is set up so that once a call is made to an emergency telephone number, it must be answered. Should the caller abandon the call, the line may still be held until the emergency service answers and releases the call.

Mathematical fallacy

In mathematics, certain kinds of mistaken proof are often exhibited, and sometimes collected, as illustrations of a concept of mathematical fallacy. There is a distinction between a simple mistake and a mathematical fallacy in a proof: a mistake in a proof leads to an invalid proof just in the same way, but in the best-known examples of mathematical fallacies, there is some concealment in the presentation of the proof. For example, the reason validity fails may be a division by zero that is hidden by algebraic notation. There is a striking quality of the mathematical fallacy: as typically presented, it leads not only to an absurd result, but does so in a crafty or clever way. Therefore, these fallacies, for pedagogic reasons, usually take the form of spurious proofs of obvious contradictions. Although the proofs are flawed, the errors, usually by design, are comparatively subtle, or designed to show that certain steps are conditional, and should not be applied in the cases that are the exceptions to the rules.

Fox News Channel

Fox News Channel (FNC), also known as Fox News, is an American basic cable and satellite news television channel that is owned by the Fox Entertainment Group subsidiary of 21st Century Fox. As of February 2015, approximately 94,700,000 American households (81.4% of cable, satellite & telco customers) receive the Fox News Channel. The channel broadcasts primarily from studios at 1211 Avenue of the Americas, New York City, New York. .

The channel was created by Australian-American media mogul Rupert Murdoch, who hired former Republican Party media consultant and NBC executive Roger Ailes as its founding CEO. It launched on October 7, 1996, to 17 million cable subscribers. It grew during the late 1990s and 2000s to become the dominant cable news network in the United States.

Fox News Channel has been accused of biased reporting and promoting the Republican Party. The channel has also been cited as detrimental to the integrity of news overall. Fox News Channel employees have responded that news reporting operates independently of its opinion and entertainment, and have denied bias in news reporting.

Fox News Live

Fox News Live is an American news/talk television program, the hard-news daytime programming of the Fox News Channel. In addition, it also referred to the short headline segments of nearly every hour daily.

About

The show featured news, guest analysis, and interviews. Like other American cable news stations, there is news mixed with feature-like stories, as well as commentary and short debates between people on opposite sides of issues, usually between associates of candidates and officials, think-tank members, and journalists.

The headline segments, shown during every non–hard news hour throughout the day, were usually two-to-three-minute recaps of the news of the day, unique to Fox News Channel with an added timestamp on the intro graphic.

Supplementing headline updates, FNC introduced a fast-paced version of these headline updates in 2006, called "Fox Real Time," which appeared during live news coverage, typically only being one-minute in length. After the first year of their introduction, their appearances greatly diminished, and eventually only appeared during hours of Weekend Live
