<a href="http://en.wikipedia.org/wiki/Interexchange_carrier#Carrier_identification_code">Carrier Access Codes</a> are a largely dated*, though still functional service to select your long-distance telephone carrier per phone call. <a href="http://en.wikipedia.org/wiki/10-10-321">In the United States</a>, these "<a href="http://abtolls.com/compare/dialaround/dialaroundhome.html">dial-around codes</a>" reached a (commercial) peak in the late 1990s, as seen with ads featuring such semi-notables as <a href="https://www.youtube.com/watch?v=qPbB7TKCaz8">Marla Gibbs, Christine Taylor and Reginald VelJohnson</a>, <a href="https://www.youtube.com/watch?v=OffIV8LsBfM">Harry Anderson</a>, <a href="https://www.youtube.com/watch?v=QAeV-AWBCKI">John Lithgow</a>, <a href="https://www.youtube.com/watch?v=Gj2Xb_5YAXs">Tony Danza</a>, <a href="https://www.youtube.com/watch?v=t2ZJVgD0v9k">Doug Flutie</a>, and even <a href="https://www.youtube.com/watch?v=iW8uP-NpqhA">Alf and some well-known friends</a>. If you're at all interested in this sort of telephony, <a href="http://tim.omghax.ca/?page_id=10">here's a blog post about features in various Carrier Access Codes in Alberta</a>, and then there's <a href="http://www.dialaroundworld.com/">Dial Around World</a>, with its 2011 recommendations and <a href="http://www.dialaroundworld.com/dial_around_pic_codes.htm">extensive collection of dial around codes</a>. And if you're wondering about the shift from 10-XXX to 10-10-XXX, <a href="http://articles.dailypress.com/1998-07-01/business/9806300168_1_long-distance-three-digit-codes-dial">that happened in 1998</a>, due to an increase in long-distance carriers in the previous years.
* The decline of dial around codes (or at least the once ubiquitous nature of their commercials) can likely be attributed to the proliferation of mobile phones, as <a href="http://en.wikipedia.org/wiki/Interexchange_carrier#Interexchange_carriers_and_mobile_phones">wireless carriers in the US and Canada are not required to support these codes</a>. tag:metafilter.com,2014:site.137858Sat, 29 Mar 2014 17:37:29 -0800filthy light thiefOh seven nine oh four seven nine

<a href="http://www.wired.com/wiredscience/2013/03/computers-and-math/all/">Using computer systems for doing mathematical proofs</a> - "With the proliferation of <a href="http://en.wikipedia.org/wiki/Computer-assisted_proof">computer-assisted proofs</a> that are all but impossible to check by hand, Hales thinks computers must become the judge." <blockquote>Three years ago, Vladimir Voevodsky, one of the organizers of a new program on the foundations of mathematics at the Institute for Advanced Study in Princeton, N.J., discovered that a formal logic system that was developed by computer scientists, called "<a href="http://en.wikipedia.org/wiki/Type_theory">type theory</a>" could be used to re-create the entire mathematical universe from scratch. Type theory is consistent with the mathematical axioms, but couched in the language of computers. Voevodsky believes this alternative way to formalize mathematics, which he has renamed the <a href="http://video.ias.edu/univalent/voevodsky">univalent foundations of mathematics</a>, will streamline the process of formal theorem proving. Voevodsky and his team are adapting a <a href="https://plus.google.com/u/0/117663015413546257905/posts/4BZRibN6iKQ">program named Coq</a>, which was designed to formally verify computer algorithms, for use in abstract mathematics.</blockquote>

Leonardo of Pisa, better known today as Fibonacci, is largely responsible for the adoption of the Hindu–Arabic numeral system in Europe, which revolutionized not only mathematics but commerce and trade as well. How did the system spread from the Arab world to Europe, and what would our lives be without it?" tag:metafilter.com,2013:site.126041Sat, 16 Mar 2013 15:33:01 -0800kliulessWhat-If Numbers

It drives home the essential weirdness of the mathematical universe and raises penetrating questions not only about the nature of this universe but about the nature of the human mind that can comprehend it. One of the biggest questions concerns the nature of reality itself. Physics has also revealed counter-intuitive truths about the universe like the curvature of space-time, the duality of waves and particles and the spooky phenomenon of entanglement, but these truths undoubtedly have a real existence as observed through exhaustive experimentation. But what do the bizarre truths revealed by mathematics actually mean? Unlike the truths of physics they can't exactly be touched and seen. Can some of these such as the perceived differences between two kinds of infinities simply be a function of human perception, or do these truths point to an objective reality 'out there'? If they are only a function of human perception, what is it exactly in the structure of the brain that makes such wondrous creations possible? In the twenty-first century when neuroscience promises to reveal more of the brain than was ever possible, the investigation of mathematical understanding could prove to be profoundly significant." tag:metafilter.com,2013:site.124535Sat, 02 Feb 2013 09:14:26 -0800kliulessNumberphile: videos about numbers and stuff

<a href="http://arxiv.org/abs/1209.2007">What is the smallest prime?</a> "It seems that the number two should be the obvious answer, and today it is, but it was not always so. There were times when and mathematicians for whom the numbers one and three were acceptable answers. To find the first prime, we must also know what the first positive integer is. Surprisingly, with the definitions used at various times throughout history, one was often not the first positive integer (some started with two, and a few with three). In this article, we survey the history of the primality of one, from the ancient Greeks to modern times. We will discuss some of the reasons definitions changed, and provide several examples. We will also discuss the last significant mathematicians to list the number one as prime." tag:metafilter.com,2012:site.120047Tue, 18 Sep 2012 13:42:13 -0800escabecheCounting Rhos
