You Learn Something New Every Day

The Earth has 657 more barrier islands than previously thought, according to a new global survey by researchers from Duke University and Meredith College in Raleigh, N.C.

The researchers identified a total of 2,149 barrier islands worldwide using satellite images, topographical maps and navigational charts. The new total is significantly higher than the 1,492 islands identified in a 2001 survey conducted without the aid of publicly available satellite imagery.

This exemplifies how science is a useful tool for mankind -- a tool in constant need of sharpening. No matter how many times this tool of Man's fashioning proves that his knowledge has limits, he continues walking the Earth smug in the belief that he knows more than he actually knows. It's part of the human condition.
