What if the old curmudgeon teaching economics married that cute, brainy geography teacher?

Or, was it the cute curmudgeon teaching econ and the old cartographer in geography?

I think I’ll add this to my TAKS review.  What other classroom uses can you find for it?

I found it at Cool InfoGraphics.

Seriously, geography and economics teachers, this is big stuff:

Follow the Money” is a video summarizing the results from the project by Northwestern University grad students Daniel Grady and Christian Thiemann.  Using data from the website Where’s George?, they have been able to track the movement of U.S. paper currency.  What can you learn from this?  That there are natural borders within the U.S. that don’t necessarily follow state borders, and it can also be used to predict the spread of disease because it maps movement of people within the U.S.

From Maria Popova on BrainPickings.org: This may sound like dry statistical uninterestingness, but the video visualization of the results is rather eye-opening, revealing how money — not state borders, not political maps, not ethnic clusters — is the real cartographer drawing our cultural geography.  The project was a winner at the 2009 Visualization Challenge sponsored by the National Science Foundation and AAA.

Missed anniversary: Naming of Americas

According to the Associated Press, Marin Waldseemueller is the cartographer who decided to name the New World continents after Amerigo Vespucci, an Italian navigator who had made a voyage to the Americas and then wrote a book about what he saw.  The book sold well in Europe, but became a runaway when an unscrupulous printer spiced up Vespucci’s story with tales of sex.

Waldseemueller’s map was published in 1507, on April 25.

The one surviving copy of the map was purchased by the Library of Congress for $10 million, in 2001.

Vespucci’s account described land and peoples that clearly were not from East Asia, to canny and alert readers.  Waldseemueller was widely read, and on the basis of Vespucci’s account and other accounts from China, concluded the lands Columbus discovered were separate from Asia.

Waldseemueller accurately protrayed the width of South America to within 70 miles in some places, and appears to have been the first to predict the presence of a wide ocean between the Americas and Asia — the Pacific not being “discovered” by Europeans until 1513, six years after this map.

Big thanks to Jessica Palmer at Bioephemera for those last two resources; her report on the display of the map at the Library of Congress is really, really useful.
