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]

David McCandless - Statistics Imagery 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.

Crime Mapping San Francisco Notice anything different?We’ve been working on the interface design, read more about it on the blog. San Francisco Crimespotting is an interactive map of crimes in San Francisco and a tool for understanding crime in cities. If you hear sirens in your neighborhood, you should know why. Crimespotting makes this possible with interactive maps and RSS feeds of crimes in areas that you care about. We’ve found ourselves frustrated by the proprietary systems and long disclaimers that ultimately limit information available to the public. Instead of simply knowing where a crime took place, we would like to investigate questions like: Is there more crime this week than last week? If the local papers didn’t report a rash of car break-ins in your neighborhood, how would you know? We believe that civic data should be exposed to the public in a more open way. This project is a work in progress; a way of discovering what kinds of questions we can ask.

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. Note: Special symbols in this file that are outside the Latin-1 character set (ISO 8859-1) are represented by a .gif image for each character. The alt tag for each image gives the name of the character. 1. Elementary or "naive" set theory is used to define basic mathematical structures. Curly braces are used to enclose a set specification. 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 .
