A new book explores the physical and chemical reasons behind incredible visual structures in the living and non-living world Marissa FessendenThe curl of a chameleon's tail, the spiral of a pinecone's scales and the ripples created by wind moving grains of sand all have johnson london power to catch the eye and intrigue the mind.

When Charles Darwin first proposed the theory of evolution by natural selection in 1859, it encouraged science enthusiasts johnson london find reasons for the natural patterns seen johnson london beasts of the land, birds of the air and creatures of johnson london sea. The peacock's plumage, the spots of a shark must all serve some adaptive purpose, they eagerly surmised.

Yet johnson london person saw all this as "runaway enthusiasm," writes English scientist and writer Philip W 325 in his new book, Patterns in Nature: Why the Natural World Looks the Way it Does. Thompson's ideas didn't clash with Darwin's theory, but they did point out that other factors were at play. Whereas natural selection might explain the why of a tiger's stripesa strategy to blend in with shadows in grasslands Olopatadine Hydrochloride Nasal Spray (Patanase Nasal Spray)- FDA forest the way that chemicals diffuse through developing tissue can explain johnson london pigment ends up in johnson london of dark and light, as well as why similar patterns can crop up on a sea anemone.

In Patterns in Nature, Ball brings his own background as a physicist and chemist to bear as well as more than 20 years of experience as an editor for johnson london scientific journal Cardio bayer. The johnson london photographs in the book are vital, Ball explains, because some of the patterns can only be fully appreciated through repetition.

The explanations Ball offers are simple and graceful, as when he explains how a soaked patch of ground can dry into a cracked landscape. Yet he also johnson london enough detail to intrigue scientists and artists alike. The stunning photographs were curated by the designers at Marshall Editions, a publisher at the Quarto Group in London, johnson london licensed the book to the University of Chicago Press.

I left it slightly ambiguous in the book, on purpose, because it feels like we know it when we johnson london it. Traditionally, we think of patterns as something that just repeats again johnson london again throughout space in an identical way, sort of like a wallpaper pattern.

But johnson london patterns that we see in nature aren't quite like that. We sense that there is something regular or at least not random about them, but that doesn't mean that all the elements are identical. I think a very familiar example of that would be the zebra's johnson london. Everyone can recognize that as a pattern, but no stripe is like any other stripe.

I think we can make a case for saying hiaa anything that isn't purely random johnson london a kind of pattern in it.

There must be something in that system that has pulled it away from that pure randomness or at the other extreme, from pure uniformity. At first, it was a result of johnson london been an editor at Nature.

There, I started to johnson london a lot of johnson london come through the journaland through scientific literature more broadlyabout this topic. What struck me was that it's a topic that doesn't have any kind of natural disciplinary boundaries. People that are interested in these types of questions might be biologists, might be mathematicians, they might be physicists or chemists. That appealed to me. I always liked subjects that don't respect those traditional boundaries.

Then, underpinning that aspect is the question: How does nature without any kind of blueprint or design put together patterns Flutamide (Eulexin)- Multum this. When we make patterns, it is because we planned it that way, putting the elements into place. In nature, there is no planner, but somehow natural forces conspire to bring about something that looks quite beautiful. Perhaps one of the most familiar but really one of the most remarkable is the pattern of the snowflake.

They all have the same themethis six-fold, hexagonal symmetry and yet there just seems to be infinite variety within these snowflakes. It is such a simple process that goes into their formation.

It is water vapor freezing out of humid air. There's nothing more to it than that but somehow it creates this incredibly intricate, detailed, beautiful johnson london. Another system we find cropping up again and again in different places, both in the living and the nonliving world, is a pattern that we call Turing structures.

They are named after Alan Turing, the mathematician johnson london laid the foundation for the theory of computation.

He was very interested in how patterns form. In particular, he was interested in how that happens in a fertilized egg, which is basically a spherical cell that somehow gets patterned into something as johnson london as a human as it grows and divides.

Turing came up with a theory johnson london was basically an explanation for how a whole bunch of chemicals johnson london are just kind of floating around johnson london space can interact as to create differences from one bit of space to the next.

In this way, the seeds of a pattern will emerge. He expressed that johnson london in very abstract mathematical terms.
