This is the only book dedicated to the Geometry of Polycentric Ovals. It includes problem solving constructions and mathematical formulas. For anyone interested in drawing or recognizing an oval, this book gives all the necessary construction and calculation tools. More than 30 basic construction problems are solved, with references to Geogebra animation videos, plus the solution to the Frame Problem and solutions to the Stadium Problem. A chapter (co-written with Margherita Caputo) is dedicated to totally new hypotheses on the project of Borromini’s oval dome of the church of San Carlo alle Quattro Fontane in Rome. Another one presents the case study of the Colosseum as an example of ovals with eight centres. The book is unique and new in its kind: original contributions add up to about 60% of the whole book, the rest being taken from published literature (and mostly from other work by the same author). The primary audience is: architects, graphic designers, industrial designers, architecture historians, civil engineers; moreover, the systematic way in which the book is organised could make it a companion to a textbook on descriptive geometry or on CAD.

The most complete collection of classic salmon fly patterns ever compiled.

An essential resource for all students and scholars of early childhood education, this book offers a rich array of material about Maria Montessori and the Montessori Method. Distinguished education scholar Gerald Gutek begins with an in-depth biography of Montessori, exploring how a determined young woman overcame the obstacles that blocked her educational and career opportunities in Italy during the late Victorian age. The author then analyzes the sources and influences that shaped the Montessori philosophy of education. After laying the foundation for Montessori's development, Gutek presents an annotated and abridged edition of The Montessori Method (1912), the seminal work that introduced her educational innovations to a U.S. audience. The book concludes with key historical documents, including disciple Anne E. George's notes on the Montessori lectures and William H. Kilpatrick's critique of the Montessori method. Preserving the historical context of Montessori's contribution, Gutek also shows the continuing relevance of her thought to educational reform in the twenty-first century.
