Statistical Visualization For his book The Visual Miscellaneum, David McCandless, along with Lee Byron, had a look at breakups on Facebook, according to status updates. They looked for the phrase "we broke up because" in status updates, and then graphed the frequencies over time. Why they couldn't just look at updates to relationship status, I'm not sure. Notice the peak leading up to the holiday season and spring cleaning. Finally, there's the highlight of Mondays, which you might lead you to believe that people like to call it quits during the beginning of the week. [Information is Beautiful | Thanks, Elise]

Visual Mapping.com Monophyletic, Polyphyletic, & Paraphyletc Taxa Concepts of monopoly, polyphyly, & paraphyly A taxon (pl. taxa) is any group of organisms that is given a formal taxonomic name. Loosely, a monophyletic taxon is one that includes a group of organisms descended from a single ancestor , whereas a polyphyletic taxon is composed of unrelated organisms descended from more than one ancestor. These loose definitions fail to recognize the fact that all organisms are related, therefore any conceivable group is logically "monophyletic". Well-known monophyletic taxa include Mammalia and Aves (modern birds), recognizable as all furry and feathered vertebrates, respectively. Taxonomists tend to fall into two schools, "Evolutionary" or "traditional" systematics versus "Phylogenetic" or "cladistic" systematics. An unfortunate circumstance for the student is that the two schools use the same terms, but in different ways, and often refuse to recognize the alternative usage.

SimPy: Simulating Systems in Python by Klaus Müller and Tony Vignaux 02/27/2003 Simulating complex real-world systems is now possible with SimPy , an open source simulation package. SimPy, originally developed by the authors of this article, has been developed to production quality by a small team of enthusiastic open sourcerers around the world. As far as we know, it is the only existing discrete event Python simulation package. Actually, it is one of a very small number of fully object oriented simulation systems. Why consider simulation? To demonstrate using SimPy for simulation we will study a simple scenario. When customers call they may have to wait for a free line. To model "quality of service", we label a customer "happy" or "unhappy" depending on wait time. SimPy Setting up a simulation requires modeling the system under study, capturing the essential entities and their interactions, and then writing code to make the model executable. Simulated entities in SimPy are objects of the Process class. yield hold,self,t

Beautiful Word Clouds indiemapper is free - Axis Maps Blog by David Heyman on January 5, 2012 With the start of 2012, we’ve decided to make indiemapper free to use. Since indiemapper launched in 2010, our business has grown and changed to where supporting and maintaining indiemapper is no longer a major part of what we do at Axis Maps every day. We’re making indiemapper free so that it can continue to exist as a useful tool for map-makers while freeing us up to be as awesome as possible at our custom cartography business. To allow us to give it away for free, we’re scaling back what indiemapper does. We’re really happy about this change and we hope you are too. Launch indiemapper Mathematical Background This web page is a revised and extended version of Appendix A from the book Conceptual Structures by John F. Sowa. It presents a brief summary of the following topics for students and general readers of that book and related books such as Knowledge Representation and books on logic, linguistics, and computer science.

This specifies a set consisting of the four integers 1, 97, 63, and 12. If the set is very large, like the set of all mammals, a complete listing is impossible. {x | vertebrate(x) and warmBlooded(x) and hasHair(x) and lactiferous(x)} {1, 2, 3} {x | x is an integer and 0<x<4} {x | x is a positive integer, x divides 6, and x .
