Input for Carnival of Math: Number 115, October 2014
Input for Carnival of Math: Number 115, October 2014 I visited Singapore in 1996 and the people were very kind to me. So I though this might be a little payback for their kindness. Good Luck. David Brooks The “Mathematical Association of America” (http://maanumberaday.blogspot.com/2009/11/115.html ) notes that: 115 = 5 x 23. 115 = 23 x (2 + 3). 115 has a unique representation as a sum of three squares: 3 2 + 5 2 + 9 2 = 115. 115 is the smallest three-digit integer, abc , such that ( abc )/( a*b*c) is prime : 115/5 = 23. STS-115 was a space shuttle mission to the International Space Station flown by the space shuttle Atlantis on Sept. 9, 2006. The “Online Encyclopedia of Integer Sequences” (http://www.oeis.org) notes that 115 is a tridecagonal (or 13-gonal) number. Also, 115 is the number of rooted trees with 8 vertices (or nodes). If you do a search for 115 on the OEIS website you will find out that there are 7,041 integer sequences that contain the number 115. The website “Positive Integers” (http://www.positiveintegers.org/115) notes that 115 is a palindromic and repdigit number when written in base 22 (5522). The website “Number Gossip” (http://www.numbergossip.com) notes that: 115 is the smallest three-digit integer, abc, such that (abc)/(a*b*c) is prime. It also notes that 115 is a composite, deficient, lucky, odd odious and square-free number. The website “Numbers Aplenty” (http://www.numbersaplenty.com/115) notes that: It has 4 divisors, whose sum is σ = 144. -

Web 2.0 Storytellingemergence of a New Genre by Bryan Alexander and Alan Levine
Teaching and Learning Web 2.0 StorytellingEmergence of a New Genre By Bryan Alexander and Alan Levine story has a beginning, a middle, and a cleanly wrapped-up end- ing. Whether told around a campfire, read from a book, or played on a DVD, a story goes from point A to B and then C. It follows a trajectory, a Freytag Pyramid—perhaps the line of a human life or the stages of the hero’s journey. A story is told by one person or by a creative team to an audience that is usually quiet, even receptive. Or at least that’s what a story used to be, and that’s how a story used to be told. Today, with digital net- Aworks and social media, this pattern is changing. Stories now are open-ended, branching, hyperlinked, cross-media, participatory, exploratory, and unpre- dictable. And they are told in new ways: Web 2.0 storytelling picks up these new types of stories and runs with them, accelerating the pace of creation and participation while revealing new directions for narratives to flow. Bryan Alexander is Director of Research at the National Institute for Technology and Liberal Education (NITLE, http:// nitle.org). He blogs at <http://b2e.nitle.org/>. Alan Levine is Vice President, Community, and Chief Technology Officer for the New Media Consortium (NMC).

Blogs and the Narrativity of Experience
Blogs and the Narrativity of Experience José Ángel García Landa Universidad de Zaragoza [email protected] http://www.garcialanda.net Blogs and the Narrativity of Experience This paper undertakes an analysis of the narrativity of a form of discourse which has appeared recently (blogs) within the framework of an emergentist theory of narrativity and its discursive modes. The narrative/discursive characteristics of blogs emerge from a preexistent ground of more basic or less specific communicative practices; and narrative discursivity itself is an emergent phenomenon with respect to other cognitive and experiential phenomena. A number of formal and communicative characteristics of blog writing and of the blogosphere are discussed as emergent modes of experience within the pragmatic context of computer-mediated communication. _________________ 1 We shall undertake an analysis of the narrativity proper to a discursive form of recent appearance, weblogs or blogs, within the framework of an emergentist theory of narrativity and of its discursive modes. The narrative- discursive characteristics of blogs emerge from a prior basis of simpler or less specific communicative practices. And the narrativity of discourse is itself an emergent phenomenon with respect to other cognitive and experiential phenomena which necessarily underpin it, and are the basis on which its emergent nature must be defined. That is to say, there must be processes first, in order for processual representations to exist, and these representations must exist in simple forms before they give rise to complex narrative forms, associated to specific cultural and communicational contexts—for instance, the development of computer-mediated communicative interaction on the Web. Processes - Representations - Narratives - Narratologies Let us begin with absolute generality—with the narrativity of experience itself, situating narratives, and narratology, within an emergentist/evolutionary theory of reality. -
The Entropy Conundrum: a Solution Proposal
OPEN ACCESS www.sciforum.net/conference/ecea-1 Conference Proceedings Paper – Entropy The Entropy Conundrum: A Solution Proposal Rodolfo A. Fiorini 1,* 1 Politecnico di Milano, Department of Electronics, Information and Bioengineering, Milano, Italy; E- Mail: [email protected] * E-Mail: [email protected]; Tel.: +039-02-2399-3350; Fax: +039-02-2399-3360. Received: 11 September 2014 / Accepted: 11 October 2014 / Published: 3 November 2014 Abstract: In 2004, physicist Mark Newman, along with biologist Michael Lachmann and computer scientist Cristopher Moore, showed that if electromagnetic radiation is used as a transmission medium, the most information-efficient format for a given 1-D signal is indistinguishable from blackbody radiation. Since many natural processes maximize the Gibbs- Boltzmann entropy, they should give rise to spectra indistinguishable from optimally efficient transmission. In 2008, computer scientist C.S. Calude and physicist K. Svozil proved that "Quantum Randomness" is not Turing computable. In 2013, academic scientist R.A. Fiorini confirmed Newman, Lachmann and Moore's result, creating analogous example for 2-D signal (image), as an application of CICT in pattern recognition and image analysis. Paradoxically if you don’t know the code used for the message you can’t tell the difference between an information-rich message and a random jumble of letters. This is an entropy conundrum to solve. Even the most sophisticated instrumentation system is completely unable to reliably discriminate so called "random noise" from any combinatorially optimized encoded message, which CICT called "deterministic noise". Entropy fundamental concept crosses so many scientific and research areas, but, unfortunately, even across so many different disciplines, scientists have not yet worked out a definitive solution to the fundamental problem of the logical relationship between human experience and knowledge extraction. -
