Math Encounters – The Museum of Mathematics Math Encounters Next presentation: “Peeling the World” Oct 1 at 4:00 PM by David Swart “Peeling the World” Oct 1 at 6:30 PM by David Swart The world is filled with spherical imagery: patterns on soccer balls, panoramic photos, and even the globe itself. How can the curved surface of a sphere be flattened to fit on the planes (paper, computer screens) we use every day? Copula (probability theory) Sklar's Theorem states that any multivariate joint distribution can be written in terms of univariate marginal distribution functions and a copula which describes the dependence structure between the variables. Copulas are popular in high-dimensional statistical applications as they allow one to easily model and estimate the distribution of random vectors by estimating marginals and copulae separately. There are many parametric copula families available, which usually have parameters that control the strength of dependence. Some popular parametric copula models are outlined below. Two-dimensional copulas are known in some other areas of mathematics under the name permutons and doubly-stochastic measures. Consider a random vector

Things To Tweak / Fix After Installing Ubuntu 11.04 Natty Narwhal A note before reading this post: before giving up on Unity without giving it a try... don't. Try Unity for a few days - yes, it's not a finished product but it's actually quite interesting - and if you don't like it then switch. If you've just upgraded to Ubuntu 11.04 Natty Narwhal, there are probably a few things you'll miss, so here is how to get them back as well as some other things you may find useful. Install CompizConfig Settings Manager and Tweak Unity to better suit your needs:

Concise Encyclopedia of Economics Harry Johnson, a Canadian, was one of the most active and prolific economists of all time. His main research was in the area of international trade, international finance, and monetary policy. One of Johnson's early articles on international trade showed that a country with monopoly power in some good could impose a tariff and be better off, even if other countries retaliated against the tariff. Propositional calculus - Wikipedia Propositional calculus (also called propositional logic, sentential calculus, sentential logic, or sometimes zeroth-order logic) is the branch of logic concerned with the study of propositions (whether they are true or false) that are formed by other propositions with the use of logical connectives, and how their value depends on the truth value of their components. Logical connectives are found in natural languages. In English for example, some examples are "and" (conjunction), "or" (disjunction), "not” (negation) and "if" (but only when used to denote material conditional). The following is an example of a very simple inference within the scope of propositional logic: Premise 1: If it's raining then it's cloudy. Premise 2: It's raining.

Semir Zeki: Beauty is in the brain of the beholder Beauty isn’t in the eye of the beholder – it’s in the brain, according to a 2011 paper in the online journal PLoS One. And in a very specific part of the braia, too: the medial orbito-frontal cortex, located just behind the eyes. That’s according to co-author of the new PLoS One paper and brain expert Professor Semir Zeki, of the University College London.

The Beauty of Mathematics: A Visual Demonstration of Math in Everyday Life This lovely video short from Yann Pineill and Nicolas Lefaucheux of Paris video production agency Parachutes succinctly demonstrates the underlying mathematics behind everyday occurrences in the format of a triptych. On the left we see the mathematical equation, in the middle a mathematical model, and on the right a video of such things as snowflakes, wind, sound, trees and magnetism. The video begins with the following quote: “Mathematics, rightly viewed, possesses not only truth, but supreme beauty — a beauty cold and austere, without the gorgeous trappings of painting or music.”

List of matrices - Wikipedia Several important classes of matrices are subsets of each other. Further ways of classifying matrices are according to their eigenvalues or by imposing conditions on the product of the matrix with other matrices. Finally, many domains, both in mathematics and other sciences including physics and chemistry have particular matrices that are applied chiefly in these areas. Matrices with explicitly constrained entries[edit] The following lists matrices whose entries are subject to certain conditions. Many of them apply to square matrices only, that is matrices with the same number of columns and rows. Elective in Robotics Elective in Robotics 2013/2014 Information Audience Students of the Master in Artificial Intelligence and Robotics (MARR) at the Dipartimento di Ingegneria informatica, automatica e gestionale (DIAG) of the Università di Roma "La Sapienza".
