Vaka (song)

"untitled #1", also known as "Vaka" and released as "untitled #1 (a.k.a. "Vaka")" was Sigur Rós' 2003 single and DVD, from the October 2002 album ( ). As late as November 12, 2006, the single remained fifteenth in the Canadian singles chart, having spent a total of 16 weeks in the top 20.

The band closed their set with tracks 2 and 3 from this single during their spring 2003 tour, calling the two songs "Smáskífa" (single) on their set list. Track 2 was originally meant to be a remix of "Vaka" but it turned out into a different song altogether, although some remnants of "Vaka"'s melody can still be heard. Track 3 features a solo on piano by drummer Orri Páll Dýrason. Track 4 is the music looped before and after Sigur Rós' live shows.

The single was released as a 3" limited mini CD, 5" CD with DVD, and as a 10" limited vinyl gatefold sleeve with an artwork stencil. The 3" mini CD was only released in Europe, and is labeled as featuring a new 12 minute track though there are four separate tracks on the disc. The DVD accompanying the 5" CD contains the first three music videos the band has made: "Svefn-g-englar", "Viðrar vel til loftárása" and "Vaka". The menu screen has a video which the band shot of some birds on a wire, with track four from the single playing.

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.

112 (emergency telephone number)

112 is the common emergency telephone number that can be dialed free of charge from most mobile telephones and, in some countries, fixed telephones in order to reach emergency services (ambulance, fire and rescue, police).

112 is a part of the GSM standard and all GSM-compatible telephone handsets are able to dial 112 even when locked or with no SIM card present. It is also the common emergency number in all member states of the European Union as well as several other countries of Europe and the world. 112 often available alongside other numbers traditionally used in the given country to access emergency services. In some countries, calls to 112 are not connected directly but forwarded by the GSM network to local emergency numbers (e.g., 911 in North America or 000 in Australia).

112 is not always supported by VoIP operators or on non-GSM networks.

Origins

112 was first standardised by a Recommendation by the CEPT in 1972 and later by a decision of the EU Council in 1991 and subsequently reaffirmed in 2002 by article 26 of the Universal Service Directive and its subsequent amendments.
