I’ve often considered that there should be a way, with today’s mapping software, to create political districts which are color-blind. Now, Robert Zubrin explains how that might work:

The degree of contrivance behind the design of a set of districts is directly related to the oddness of the shapes employed to reach the election-rigging objective. There is a precise mathematical way to measure such malformation. That is, if you take the square of the perimeter of any shape, and divide it by the shape’s area, you arrive at a number, which can be called its

irregularity.For example the irregularity of any square, regardless of its size, equals 16 (because (4s)^{2}/s^{2}= 16.) On the other hand, the irregularity of a rectangle whose long side is 10 times the length of its short side is 48.4 (because (22s)^{2}/10s^{2}= 48.4.) The odder and more contrived the shape, the higher will be its irregularity.

Go and read it all.

I knew there was a reason I was in favor of teach readin’, writin’ and ‘rithmatic.
