Book Description
The Book of Squares by Fibonacci is a gem in the mathematical literature and one of the most important mathematical treatises written in the Middle Ages. It is a collection of theorems on indeterminate analysis and equations of second degree which yield, among other results, a solution to a problem proposed by Master John of Palermo to Leonardo at the Court of Frederick II. The book was dedicated and presented to the Emperor at Pisa in 1225. Dating back to the 13th century the book exhibits the early and continued fascination of men with our number system and the relationship among numbers with special properties such as prime numbers, squares, and odd numbers. The faithful translation into modern English and the commentary by the translator make this book accessible to professional mathematicians and amateurs who have always been intrigued by the lure of our number system.

Book Description
When ungroovy scientists did groovy science: how non-activist scientists and engineers adapted their work to a rapidly changing social and political landscape. In The Squares, Cyrus Mody shows how, between the late 1960s and the early 1980s, some scientists and engineers who did not consider themselves activists, New Leftists, or members of the counterculture accommodated their work to the rapidly changing social and political landscape of the time. These “square scientists,” Mody shows, began to do many of the things that the counterculture urged: turn away from military-industrial funding, become more interdisciplinary, and focus their research on solving problems of civil society. During the period Mody calls “the long 1970s,” ungroovy scientists were doing groovy science. Mody offers a series of case studies of some of these collective efforts by non-activist scientists to use their technical knowledge for the good of society. He considers the region around Santa Barbara and the interplay of public universities, think tanks, established firms, new companies, philanthropies, and social movement organizations. He looks at Stanford University’s transition from Cold War science to commercialized technoscience; NASA’s search for a post-Apollo mission; the unsuccessful foray into solar energy by Nobel laureate Jack Kilby; the “civilianization” of the US semiconductor industry; and systems engineer Arthur D. Hall’s ill-fated promotion of automated agriculture.

Book Description
We are what we eat, as the saying goes, but we are also how we eat, and when, and where. Our eating habits reveal as much about our society as the food on our plates, and our national identity is written in the eating schedules we follow and the customs we observe at the table and on the go. In Three Squares, food historian Abigail Carroll upends the popular understanding of our most cherished mealtime traditions, revealing that our eating habits have never been stable—far from it, in fact. The eating patterns and ideals we’ve inherited are relatively recent inventions, the products of complex social and economic forces, as well as the efforts of ambitious inventors, scientists and health gurus. Whether we’re pouring ourselves a bowl of cereal, grabbing a quick sandwich, or congregating for a family dinner, our mealtime habits are living artifacts of our collective history—and represent only the latest stage in the evolution of the American meal. Our early meals, Carroll explains, were rustic affairs, often eaten hastily, without utensils, and standing up. Only in the nineteenth century, when the Industrial Revolution upset work schedules and drastically reduced the amount of time Americans could spend on the midday meal, did the shape of our modern “three squares” emerge: quick, simple, and cold breakfasts and lunches and larger, sit-down dinners. Since evening was the only part of the day when families could come together, dinner became a ritual—as American as apple pie. But with the rise of processed foods, snacking has become faster, cheaper, and easier than ever, and many fear for the fate of the cherished family meal as a result. The story of how the simple gruel of our forefathers gave way to snack fixes and fast food, Three Squares also explains how Americans’ eating habits may change in the years to come. Only by understanding the history of the American meal can we can help determine its future.

Book Description
In this important collection, eighteen renowned writers, including David Remnick, Zadie Smith, Rebecca Skloot, Rory Stewart, and Adam Gopnik evoke the spirit and history of some of the world’s most recognized and significant city squares, accompanied by illustrations from equally distinguished photographers. Over half of the world’s citizens now live in cities, and this number is rapidly growing. At the heart of these municipalities is the square—the defining urban public space since the dawn of democracy in Ancient Greece. Each square stands for a larger theme in history: cultural, geopolitical, anthropological, or architectural, and each of the eighteen luminary writers has contributed his or her own innate talent, prodigious research, and local knowledge. Divided into three parts: Culture, Geopolitics, History, headlined by Michael Kimmelman, David Remnick, and George Packer, this significant anthology shows the city square in new light. Jehane Noujaim, award-winning filmmaker, takes the reader through her return to Tahrir Square during the 2011 protest; Rory Stewart, diplomat and author, chronicles a square in Kabul which has come and gone several times over five centuries; Ari Shavit describes the dramatic changes of central Tel Aviv’s Rabin Square; Rick Stengel, editor, author, and journalist, recounts the power of Mandela’s choice of the Grand Parade, Cape Town, a huge market square to speak to the world right after his release from twenty-seven years in prison; while award-winning journalist Gillian Tett explores the concept of the virtual square in the age of social media. This collection is an important lesson in history, a portrait of the world we live in today, as well as an exercise in thinking about the future. Evocative and compelling, City Squares will change the way you walk through a city. Contributors include: David Adjaye on Jemma e-Fnna, Marrakech • Anne Applebaum on Red Square, Moscow and Grand Market Square, Krakow • Chrystia Freeland on Euromaiden, Kiev • Adam Gopnik on Place des Vosges, Paris • Alma Guillermoprieto on Zocalo, Mexico City • Jehane Noujaim on Tahrir Square, Cairo • Evan Osnos on Tiananmen Square, Beijing • Andrew Roberts on Residential Squares, London • Elif Shafak on Taksim Square, Istanbul • Rebecca Skloot on American Town Squares • Ari Shavit on Rabin Square, Tel Aviv • Zadie Smith on the grand piazzas of Rome and Venice • Richard Stengel on Market Square, Grand Parade, Cape Town • Rory Stewart on Murad Khane, Kabul • Plus contributions by Gillian Tett, George Packer, David Remnick, and Michael Kimmelman; illustrations and photographs from renowned photographers, including: Thomas Struth, Philip Lorca di Corcia, and Josef Koudelka

Book Description
Sums of Squares of Integers covers topics in combinatorial number theory as they relate to counting representations of integers as sums of a certain number of squares. The book introduces a stimulating area of number theory where research continues to proliferate. It is a book of "firsts" - namely it is the first book to combine Liouville's elementary methods with the analytic methods of modular functions to study the representation of integers as sums of squares. It is the first book to tell how to compute the number of representations of an integer n as the sum of s squares of integers for any s and n. It is also the first book to give a proof of Szemeredi's theorem, and is the first number theory book to discuss how the modern theory of modular forms complements and clarifies the classical fundamental results about sums of squares. The book presents several existing, yet still interesting and instructive, examples of modular forms. Two chapters develop useful properties of the Bernoulli numbers and illustrate arithmetic progressions, proving the theorems of van der Waerden, Roth, and Szemeredi. The book also explains applications of the theory to three problems that lie outside of number theory in the areas of cryptanalysis, microwave radiation, and diamond cutting. The text is complemented by the inclusion of over one hundred exercises to test the reader's understanding.
