Crowd Modelling + Crowd Monitoring + Crowd Management = Safer Crowds Crowd Modelling is the scientific approach to the development of safe, robust, crowd management plans. This can be achieved without the need for expensive, complex, time consuming computer simulations. In simple terms Crowd Modelling is understanding how, where, when and why crowds arrive, move around and leave an events/venues. The majority of this can be accomplished using tried, tested and simple to apply methodologies. "Keith Still is what I term an intuitive mathematician. He is one of the most creative and original thinkers that I know. He adds drive and determination, as well as considerable intellectual power to any group of which h

Northwestern University scientists created a model to explore food web dynamics towards species conservation. "The goal of this project, funded by the National Science Foundation's Division of Mathematical Sciences, is to develop mathematical methods to study dynamical processes in complex networks. Although the specific application mentioned here may be useful in management of ecosystems, the mathematical foundation underlying the analysis is much more universal. The broad concept is innovative in the area of complex networks because it concludes that large-scale failures can be avoided by focusing on preventing the waves of failure that follow the initial event."

Applying mathematics to biology and complex life processes

The role of mathematics in complex economic problems such as the consumer price index

CK-12 Foundation's Trigonometry FlexBook is an introduction to trigonometry for the high school student. Topics include: Trigonometric Identities & Equations, Circular Functions, and Polar Equations & Complex Numbers.

Current reforms in mathematics education emphasise the need for pedagogy because it offers learners opportunities to develop their proficiency with complex high-level cognitive processes. One has always associated the ability to make mathematical connections, together with the teacher's role in teaching them, with deep mathematical understanding. This article examines the nature and quality of the mathematical connections that the teachers' representations of those connections enabled or constrained. The researchers made video recordings of four Grade 11 teachers as they taught a series of five lessons on algebra-related topics. The results showed that the teachers' representations of mathematical connections were either faulty or superficial in most cases. It compromised the learners' opportunities for making meaningful mathematical connections. The researchers concluded by suggesting that helping teachers to build their representation repertoires could increase the effectiveness of their instructional practices.

"Curiosity is the "complex feeling and cognition that accompanies a desire to learn what is unknown," according to Min Jeong Kang and fellow researchers in a 2009 study. Neurological research here focused on, among other areas, the difference in neural activity when answers are presented, and when questions are presented for both high-curiosity and low-curiosity questions."

Students in grades 3 - 5 apply area and perimeter skills to solve increasingly complex designs. The focus is rectangular spaces.

The following is a common question heard around teacher workrooms, teacher lunchrooms, faculty meetings, and science or math conferences. "Why use web 2.0 tools when teaching science or math?" The answer is both simple and complex at the same time.

Still, in today's standard-driven classrooms, math homework is more complex than ever and math homework is usually a daily event. It is very important for a student to learn the basic concepts in math before going for any math homework and for the same quality tutoring is guaranteed. The Internet is a great medium for this purpose. Math homework help services on the internet through their expert advice on the exact concepts you are working on, are just a click away 24/7.

An algebra project focusing on a theme which interests students is more likely to engage them in the project, so lets take a look at sports. Many students participate in sports at some level, whether as part of a school team or a community team. For the most part these same students do not understand the costs involved to host the sport. Also, they do not understand how much money is needed to ensure a profitable season so the sport can continue from year to year.

From the abstract (full text requires subscription): "Many organisms can predict future events from the statistics of past experience, but humans also excel at making predictions by pure reasoning: integrating multiple sources of information, guided by abstract knowledge, to form rational expectations about novel situations, never directly experienced. Here, we show that this reasoning is surprisingly rich, powerful, and coherent even in preverbal infants. When 12-month-old infants view complex displays of multiple moving objects, they form time-varying expectations about future events that are a systematic and rational function of several stimulus variables. Infants' looking times are consistent with a Bayesian ideal observer embodying abstract principles of object motion. The model explains infants' statistical expectations and classic qualitative findings about object cognition in younger babies, not originally viewed as probabilistic inferences."

Pi Cubed is a visual math application for the iPhone / iPod touch that lets you perform calculations as you would on a piece of paper. By using an animated, touch-based interface, even the most complex mathematical expressions can be entered and instantly evaluated. These expressions are typeset as they would be in a textbook or on a blackboard. Calculations are displayed with up to 34 digits of decimal precision. Additionally, a library of over 150 equations ships with the application.

Published March 2013. "The Golden Ticket provides a nontechnical introduction to P-NP, its rich history, and its algorithmic implications for everything we do with computers and beyond. In this informative and entertaining book, Lance Fortnow traces how the problem arose during the Cold War on both sides of the Iron Curtain, and gives examples of the problem from a variety of disciplines, including economics, physics, and biology. He explores problems that capture the full difficulty of the P-NP dilemma, from discovering the shortest route through all the rides at Disney World to finding large groups of friends on Facebook. But difficulty also has its advantages. Hard problems allow us to safely conduct electronic commerce and maintain privacy in our online lives. The Golden Ticket explores what we truly can and cannot achieve computationally, describing the benefits and unexpected challenges of this compelling problem."

"'The Fractalist,' Benoit B. Mandelbrot's Math Memoir"

Abstract: "In spite of the efficacy of Operations Research (OR), its tools are still underused, due to the difficulties that people experience when describing a problem through a mathematical model. For this reason, teaching how to approach and model complex problems is still an open issue. A strong relation exists between (video) games and learning: for this reason we explore to which extent (real time) simulation video games could be envisaged to be an innovative, stimulating and compelling approach to teach OR techniques."

Maria Chudnovsky, mathematician, is one of 23 MacArthur Fellowship recipients in 2012. She is an associate professor in the department of industrial engineering and operations research at Columbia University and specializes in graph theory. With colleagues she successfully solved the "Srong Perfect Graph Theorem" which was proposed in the 1960s, and her research is potentially "deepening the connections between graph theory and other major branches of mathematics, such as linear programming, geometry, and complexity theory." A video featuring the awardee can be viewed on the web site.

"Beautiful Mathematics is about beautiful mathematical concepts and creations. Mathematical ideas have an aesthetic appeal that can be appreciated by those who have the time and dedication to investigate. Mathematical topics are presented in the categories of words, images, formulas, theorems, proofs, solutions, and unsolved problems. Readers will investigate exciting mathematical topics ranging from complex numbers to arithmetic progressions, from Alcuin's sequence to the zeta function, and from hypercubes to infinity squared."
