Patterns in Nature : Branching

Last weekend I saw a book in the library called By Nature's Design (Neill/Murphy), which I found very intriguing. Human eyes instinctively look for repetitions of like features, which we call Patterns. They can be of many different kinds like the scales of fish, spiral structures of the sea shells or hexagonal shapes of the beehives. Many of them can be represented by mathematical formulas, but some are rather complex. Branching is one of them.

Branching occurs when some material (like water) is to be transported from a small source region to an extended area, or vice versa. You will see many examples of branching in both living and non-living world and in all scales from the smallest algae to the tallest trees, from the tiny blood vessels to the mighty rivers.

Here are couple of my old photos. The picture below was taken on a beach on the coast of Virginia, showing natural formation of sand patterns on an area which is about several feet across. The last one was shot from an airplane near Anchorage, Alaska. Both the pictures were taken in 1993.
