Hungarian folk dance used to demonstrate computational sorting algorithms, from Sapientia Univeristy in Romania

This is highly awesome! Computer science concepts are fun to play with, and dance is a great way to share this one. Reminds me of a TRIZ method.

"algorithm based on the arithmetic-geometric mean that rapidly converges to pi. "

A programmer/developer reflects on lessons learned in mathematics. His blog is subtitled "algorithms for the heck of it.)

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."

Subtitled "A Place for Elegant Solutions." From the author's description: "This blog is a presentation of the interesting solutions I come across, and an exploration of the deeper mathematical ideas therein. Most often this means exploring the mathematical structure of a problem to lubricate the cogs of algorithm design. In seldom cases, this involves using programs to reason about mathematical theory."

"Hicks, a professor in Drexel's College of Arts and Sciences, designed his mirror using a mathematical algorithm that precisely controls the angle of light bouncing off of the curving mirror."

A conference scheduled for July 20-21, 2011 in Bertinoro, Italy, aims at formulating strategies for a comprehensive digital mathematics literature library, addressing such considerations as algorithms, standards, technology, formats, markup languages, interoperability and publishing models.

Today's Wolfram|Alpha is the first step in an ambitious, long-term project to make all systematic knowledge immediately computable by anyone. You enter your question or calculation, and Wolfram|Alpha uses its built-in algorithms and growing collection of data to compute the answer.

See real-time data on a host of topics important to daily life around the world!! * world population (e.g., births this year, deaths today, net population growth for today) * government and economics (daily government spending by category; computers sold) * society and media (new book titles published, money spent on video games, Google searches) * environment (forest loss, carbon dioxide emissions, current average temperature) * food (tons of food produced; people who died of hunger) * water (water consumed, people with no access to safe drinking water) * energy (solar energy striking Earth; oil pumped; oil, gas, and coal left) * health (deaths caused by alcohol, suicides, road traffic accident fatalities) Worldometers' algorithm takes the latest statistical data available from the United Nations (UN), the World Health Organization (WHO), the Food and Agriculture Organization (FAO), and other institutions, and then processes them together with its estimated progression to compute figures current up to the millisecond.

Abstract: This research paper has been designed to develop an online tutoring system for pre - K to middle school Math students. The research methodology applied in this study has used both qualitative and quantitative research methods in terms of external and internal Web or software metrics to obtain the usable parameters to design an effective tutoring system to learn Math. Today online hypermedia applications are increasingly becoming more feature rich, important and also the most popular means for communication among school students for e - learning. This paper is divided into four parts: part 'I' presents the introduction of Kumon based after school education; part 'II' describes the research proposal to identify measures, model, and methodology to develop the Web - based online learning system for Pre - K to middle school math students ; part 'III' elaborates the role of using static analysis, dynamic, and comparative analysis that can be applied to check the characteristics and authenticity of data obtained for each student separately; and finally part 'IV' investigates the behaviour of online tutoring system to find the failure points and to calculate reliability aspects using Web page trace algorithms and We b page replacement policies. In this paper, an attempt has been made to systematically explain the state of the art and their practices to design, analyze, and test the functionality of online learning systems for pre - K to middle school Math students

Abstract: "In this paper, students provide insight into their use of Quick Response (QR) codes and mobile devices to assist in mathematics homework efforts. These QR codes were directly linked to instructional videos related to their unit on fraction algorithms and were hosted on YouTube. In particular, through focus-group interviews, the students identified many strengths associated with the implementation of this research. The strengths include the manner in which the YouTube clips of currently accepted instructional strategies worked to reinforce their classroom learning, how the mobile devices motivated students to complete homework in a variety of non-traditional settings, increased their communication with their classroom teacher, and how these devices engaged parents and siblings in the learning process."
