Best scientific visualizations of 2011

Hi everyone and may you have a nice month!

Did you have a chance to take a look at the beautiful visualizations at the national science foundation site : http://www.nsf.gov/news/special_reports/scivis/winners_2011.jsp

My favorite of those was this visualization of a complex function. Konstantin Poelke and Konrad Polthier from the free university of Berlin found a way to pack the information contained in four dimensions to only two, by using variations in the color and the brightness of each pixel. I really like this way of thinking and it produces very cool pictures. Here’s the official explanation from the NSF site.

To create this visualization, researchers at the Free University of Berlin assigned each complex number in their equation to a spot on a color wheel. The farther numbers get from zero, the brighter they are (white regions approach infinity). The result packs two dimensions of information (hue and brightness) into each point in the image.

The brightness and colors change according to the function

A similar visualization sits at the complex analysis post in Wikipedia.

  1. Well, the one who really found it was Hans Lundmark (see his site). The rest of your comments are obviously true.
