Though at first glance the natural world may appear overwhelming in its diversity and complexity, there are regularities running through it, from the hexagons of a honeycomb to the spirals of a seashell and the branching veins of a leaf. Revealing the order at the foundation of the seemingly chaotic natural world, Patterns in Nature explores not only the math and science but also the beauty and artistry behind nature’s awe-inspiring designs.

Unlike the patterns we create in technology, architecture, and art, natural patterns are formed spontaneously from the forces that act in the physical world. Very often the same types of pattern and form – spirals, stripes, branches, and fractals, say—recur in places that seem to have nothing in common, as when the markings of a zebra mimic the ripples in windblown sand. That’s because, as Patterns in Nature shows, at the most basic level these patterns can often be described using the same mathematical and physical principles: there is a surprising underlying unity in the kaleidoscope of the natural world. Richly illustrated with 250 color photographs and anchored by accessible and insightful chapters by esteemed science writer Philip Ball, Patterns in Nature reveals the organization at work in vast and ancient forests, powerful rivers, massing clouds, and coastlines carved out by the sea.
 
By exploring similarities such as those between a snail shell and the swirling stars of a galaxy, or the branches of a tree and those of a river network, this spectacular visual tour conveys the wonder, beauty, and richness of natural pattern formation.

It’s not what you say, but how you say it. Solving problems with words is the essence of politics, and finding the right words for the moment can make or break a politician’s career. Yet very little has been said in political science about the elusive element of tone.

In Political Tone, Roderick P. Hart, Jay P. Childers, and Colene J. Lind analyze a range of texts—from speeches and debates to advertising and print and broadcast campaign coverage— using a sophisticated computer program, DICTION, that parses their content for semantic features like realism, commonality, and certainty, as well as references to religion, party, or patriotic terms. Beginning with a look at how societal forces like diversity and modernity manifest themselves as political tones in the contexts of particular leaders and events, the authors proceed to consider how individual leaders have used tone to convey their messages: How did Bill Clinton’s clever dexterity help him recover from the Monica Lewinsky scandal? How did Barack Obama draw on his experience as a talented community activist to overcome his inexperience as a national leader? And how does Sarah Palin’s wandering tone indicate that she trusts her listeners and is open to their ideas?

By focusing not on the substance of political arguments but on how they were phrased, Political Tone provides powerful and unexpected insights into American politics.
