Hailed as one of the greatest mathematical results of the twentieth century, the recent proof of Fermat's Last Theorem by Andrew Wiles brought to public attention the enigmatic problem-solver Pierre de Fermat, who centuries ago stated his famous conjecture in a margin of a book, writing that he did not have enough room to show his "truly marvelous demonstration." Along with formulating this proposition--xn+yn=zn has no rational solution for n > 2--Fermat, an inventor of analytic geometry, also laid the foundations of differential and integral calculus, established, together with Pascal, the conceptual guidelines of the theory of probability, and created modern number theory. In one of the first full-length investigations of Fermat's life and work, Michael Sean Mahoney provides rare insight into the mathematical genius of a hobbyist who never sought to publish his work, yet who ranked with his contemporaries Pascal and Descartes in shaping the course of modern mathematics.

The dangerous work of leading change--somebody has to do it. Will you put yourself on the line? To lead is to live dangerously. It's romantic and exciting to think of leadership as all inspiration, decisive action, and rich rewards, but leading requires taking risks that can jeopardize your career and your personal life. It requires putting yourself on the line, disrupting the status quo, and surfacing hidden conflict. And when people resist and push back, there's a strong temptation to play it safe. Those who choose to lead plunge in, take the risks, and sometimes get burned. But it doesn't have to be that way say renowned leadership experts Ronald Heifetz and Marty Linsky. In Leadership on the Line, they show how it's possible to make a difference without getting "taken out" or pushed aside. They present everyday tools that give equal weight to the dangerous work of leading change and the critical importance of personal survival. Through vivid stories from all walks of life, the authors present straightforward strategies for navigating the perilous straits of leadership. Whether you're a parent or a politician, a CEO or a community activist, this practical book shows how you can exercise leadership and survive and thrive to enjoy the fruits of your labor.

Used extensively in nursing education, Betty Neuman's Systems Model reflects nursing's interest in holism and in the influence of environment on health. This volume opens with a brief biography of Betty Neuman and continues with a succinct discussion of her theory that outlines its origins, assumptions, and the major concepts of the meta-paradigm of nursing. It continues with a presentation of the propositions of the conceptual model; examples for application to practice and research; classic works, critiques, and research; and a glossary of important terms.
