Seedmagazine.com | The Seed Salon | Steven Strogatz + Carlo Ratti Nice video of Steven Strogatz and Carlo Ratti discussing complexity


Nice video of Steven Strogatz and Carlo Ratti discussing complexity
and urban design:

http://salon.seedmagazine.com/salon_strogatz_ratti.html
Strogatz mathematically describes how natural and sociocultural
complexity resolves into vast webs of order. Ratti uses technology as
a tool to create interactive urban environments. In this video Salon,
Strogatz and Ratti discuss whether building and analyzing human
networks can help us overcome our poor mathematical understanding of
complexity.

    Using Google’s Motion Chart to visualize population trends

    Posted: 09 Apr 2008 07:07 PM CDT

    In my Demographic Dashboard I have a scatter plot that shows the trend towards an aging society. Today I wanted to test the new Google Chart API and the Motion Chart with the same data set.

    The result is this (you may have to wait for the chart):

    If you click a specific country a persistent label will allow you to track its evolution.

    The spreadsheet is available here.

    If you are not familiar with the demographic concepts, this is what you need to know to understand the chart:

    * Old dependency ratio: ratio between population 65+ years old / adult population (15-64 yeas old);
    * Young dependency ratio: ratio between population 0-14 years old / adult population (15-64 yeas old);
    * Total dependency ratio is the sum of the above two.

    The chart displays the old dependency ratio against young dependency ratio. It clearly shows the shift from high ratios of young dependency to high ratios of old dependency specially in Europe and other developed countries. This means tough times ahead (the adult population will not be able to pay for social security systems, expensive medical care, etc.).

MYPOCKET: Transaction Graph - BURAK ARIKAN

  • Transactions Graph
    Transactions Graph is the network model created to generate list of predictions about future spending. It shows the unprocessed model of dynamic relationships between transaction items and their effects changing overtime. Its topology intensifies or de-inensifies depending on the quality and force of the relations. Each node represents a transaction and connected to each other through categories and dates. Thickness of connecting lines shows the total spending amount of the paired transactions. At a given timeframe, the last day's purchases and the two weeks of past spending are shown.

MYPOCKET – BURAK ARIKAN

  • MYPOCKET discloses the artist's personal financial records to the world by exploring and revealing essential patterns in the daily transactions of his bank account. These are the records that we usually keep secret, whereas financial institutions intensively analyze them to score our credibility. Archived on the site, the artist's two years of spending history is analyzed by the custom software to predict future spending; these predictions sometimes determine his future choices, creating a system in which both the software and the artist adapt to one another. Influenced by today's techno-cultural milieu, MYPOCKET presents a hybrid interface to a living physical/digital process.

Debategraph

  • Debategraph FAQ
    What do I need to use Debategraph?

    Debategraph is browser-based web-application, so there is nothing to download and install. All you need is a Windows, Macintosh or Linux computer with a modern web browser and a broadband connection.

    The current fully supported browsers are:

    * Internet Explorer 6 & 7 (Windows only),
    * Firefox 2 or later (Windows/ Mac/Linux)
    * Safari 3 or later (Windows/Mac).

    Note that client-scripting (JavaScript) must also be enabled—as it generally is by default on most computers.

The Shape of Change - Stocks and Flows

  • Description:

    In The Shape of Change (2004), by Rob Quaden, Alan Ticotsky and Debra Lyneis, students engaged in games and other classroom activities to observe what was changing over time. They drew behavior over time graphs to examine how these things changed, and they related the patterns of behavior to other changes in their experience.

    Now, with The Shape of Change: Stocks and Flows students build on the earlier lessons to understand why the changes occurred. Why did doubling cause the number of friends to grow exponentially? Why did the mammoths go extinct? Why did the boiling water cool to room temperature?

    Step-by-step, students build stock/flow maps explaining each lesson activity. These stock/flow maps are tied directly to students’ earlier behavior over time graphs and to the underlying causal loop structures that drive the changes. That way, students begin to build systems thinking skills – an understanding of how structure creates the behavior we observe all around us.

Classroom Math Resource Bank

  • Classroom Resource Bank

    http://mtl.math.uiuc.edu/classroom_resources.htm

    Over the past several years, the Math Teachers Link initiative at the University of Illinois at Urbana-Champaign has created a number of online math courses for teachers at the secondary level, along with offering additional workshops and seminars. They have also researched and compiled a set of online resources that will be of interest to those teaching mathematics and related subjects at the high school and college level. The links are divided thematically into sections that include geometry, algebra, calculus, and a special section titled “Integrating Internet Projects In Your Classroom”. [KMG]

THE CALCULUS PAGE

  • The Calculus Page

    http://www.math.ucdavis.edu/~calculus/

    From time to time over the past several centuries, the word “calculus” has caused more than a few college students to break out into a sweat and become a bit anxious. These potentially embarrassing moments can be alleviated by a visit to The Calculus Page. The site is under the direction of Professors Joel Hass and Duane Kouba, and it features dozens of links to valuable online resources that deal with this branch of mathematical inquiry and discovery. The first section of the site is dedicated to providing materials for students of calculus (including calculus animations and sample exams) and a number of resources for instructors follow. The site is rounded out by links to other relevant websites and online portals, so interested parties will definitely want to make several return visits. [KMG]

Systems thinking and practice - LearningSpace - OpenLearn - The Open University

  • What is systems thinking and practice? The essence of systems thinking and practice is in ‘seeing’ the world in a particular way, because how you ‘see’ things affects the way you approach situations or undertake specific tasks. This unit will help you to learn about the problems of defining a system and meet some of the key concepts used in systems theory: boundary, environment, positive and negative feedback, etc.
