The Macroscope

May 24, 2015 by


As a public school teacher, I frequently feel overwhelmed by the sheer amount of information I receive. I get data about student performance, about equity measures, about student’s lives and about parent’s aspirations. Yet at some point during my graduate coursework I started to rethink how I approached exactly what value I was getting from […]

Simplifying data-and why it can be dangerous

May 4, 2013 by


Is simplicity in data always desirable? Part 1 I recently stumbled on a really cool blog post looking at the alignment of buildings on the Open Street Map (OSM) database.  The author loaded the OSM database for the British Isles, and then calculated the azimuth* of each building.   His results are interesting. What does […]

Using statistics to lie, and why democracy needs statistical literacy

August 3, 2012 by

During this project, I needed to simplify some visualizations.  Not dumb down, […]

A new infographic – please comment

November 2, 2011 by

AAAS Visualization Challenge

March 2, 2011 by


Data visualization isn’t limited to the social sciences. As a case in point, the American Association for the Advancement of Science (which publishes the journal Science) recently held a competition for data visualization. There were some really cool ideas – a team from MIT tracked where pieces of trash ended up, a Russian team created a […]

Flocking algorithms in graphic design

February 21, 2011 by


What a creative visualization! From ShiftControl, nr2154, and okdeluxe, I stumbled on an image and video created for the 2009 United Nations Climate Change Conference (COP15) created from a set of flocking and force field algorithms. As they describe it, they did a good job using math to express social meaning: Consisting of 192 lines, […]
