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.

The Voice Thailand

The Voice เสียงจริงตัวจริง, (also known as The Voice Thailand) is a Thai reality television series on the Channel 3 television network. It was premiered on 9 September 2012 on Channel 3. The format is Dutch and the original Dutch version of the programme was broadcast in the Netherlands for the first time in 2010 as The Voice of Holland. The programme was commissioned after a successful first season in the U.S., where the programme aired on NBC domestically and AXN Asia regionally. It is produced by True Music and Toh-Klom Televisions

Format

The Voice is a reality television series that features four coaches looking for a talented new artist, who could become a global superstar. The show's concept is indicated by its title: the coaches do not judge the artists by their looks, personalities, stage presence or dance routines—only their vocal ability. It is this aspect that differentiates The Voice from other reality television series such as The X Factor, Britain's Got Talent or even Must Be the Music. The competitors are split into four teams, which are mentored by the coaches who in turn choose songs for their artists to perform. There is no specific age range and anyone can audition; if a coach likes what they hear, a button-press allows their chair to spin around and face the performer, signifying that they would like to mentor them. If more than one does so, then the artist selects a coach. However, if no coach turns around then the artist is sent home.
