Stewart Edward White (12 marzo 1873 - 18 settembre 1946) è stato uno scrittore, romanziere e spiritualista americano. Era un fratello del noto pittore murale Gilbert White. Dal 1900 circa fino al 1922 circa scrisse romanzi e saggi su avventura e viaggi, con particolare attenzione alla storia naturale e alla vita all'aria aperta. A partire dal 1922, lui e sua moglie Elizabeth 'Betty' Grant White scrissero numerosi libri che dicono essere stati ricevuti attraverso la canalizzazione di spiriti. Hanno anche scritto dei loro viaggi nello stato della California. White è morto a Hillsborough, in California.

This accessible book is a visual guide to understanding and identifying architectural styles and engineering techniques of all types of bridges, from ancient Roman arch bridges and nineteenth-century truss bridges prevalent in the United States, to the latest high-design cantilever and suspension bridges of the moment. It explores the elegant and varied ways in which engineers and architects have designed ever longer yet less heavy bridges, devising new methods of construction along the way. 

Illustrated throughout with detailed line drawings and cross sections, including dramatic images of the world's iconic bridges, this charming guide still fits in a pocket or purse—perfect for anyone who likes to explore the dynamic bridges and built environment on foot.

Autism has been identified as the fastest growing, serious developmental disability in the United States, where nearly 2 million people are affected. One of the most frustrating aspects of autism and similar disorders is that affected children affected do not interact with others and often seem unaware of the people and the environment around them. Therapist Densmore takes us with her as she works in a remarkable program she has developed to lead such children into the social world. Allowing readers to 'look over her shoulder' during sessions, Densmore explains Narrative Play, her approach to inspiring social contact. The work includes interviews with parents of children with autism and will be of wide interest to professionals, teachers, parents, and family members who can use the approach to help a child move into the social world. The book, and the theory it promulgates, will also interest students of psychology, special education, pediatrics, neurology, and speech.

Used today in spheres of life as diverse as business strategy, creative writing, medicine, computer science, and theoretical physics, Venn diagrams possess fascinating properties. The basic Venn diagram is both elegantly simple—three overlapping circles that intersect to create eight distinct areas—and conceptually innovative. Devised by English logician John Venn (1834–1923) to visually represent complex logical propositions and algebraic statements, the diagrams drew the excited interest of both scholars and the general public.

In Cogwheels of the Mind, statistician and geneticist A. W. F. Edwards provides an accessible and engaging history of the Venn diagram, its reception and evolution, and its presence in such objects and images as Christian iconography, tennis balls, and flags which provide a rich source of Venn diagrams for Edwards, including those of Switzerland, Poland, and Japan (all one-set Venn diagrams), Greenland (a two-set Venn diagram), and Maryland (a three-set device).

Edwards begins with a sketch of Venn's life, his discovery of the three-circle design while developing a series of lectures on symbolic logic at Cambridge University, and the publication of his find in an 1880 paper, and, more influentially, his 1881 book, Symbolic Logic. Edwards discusses the rival diagrammatic scheme invented by Charles Dodgson, better known as Lewis Carroll, who also developed a board game based on his design. The author also recreates famous Venn diagrams from history, including Winston Churchill's of 1948 depicting the mutual interests of the British Empire, a united Europe, and the English-speaking world, with the United Kingdom located at the intersection.

Edwards goes on to show how different shapes can be linked together to form artistically beautiful and mathematically important, multi-set Venn diagrams, including the author's own influential Adelaide variation. And he delineates the possibilities for expanding the analytic power of these diagrams far beyond those first appreciated by Venn. Edwards even tells readers how to draw complex Venn diagrams on a spherical surface to create 'Vennis balls.' For anyone interested in mathematics or its history, Cogwheels of the Mind is invaluable and compelling reading.
