Book excerpt: 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.

Download or read book Number Theory written by Kuldeep Singh and published by Oxford University Press, USA. This book was released on 2020 with total page 398 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This book examines the patterns and beauty of positive integers by using elementary methods. It discusses some of the outstanding problems which have not been resolved even after hundreds of years of trying. A challenging problem, even for powerful computers, is factorizing integers and the book highlights some methods that are used to simplify this. We factorize integers of the type and solve the equivalent non - linear Diophantine equation where p is prime. To see if such equations have integer solutions, we use the 'Law of Quadratic Reciprocity' which is one of the most powerful results in number theory. The methods of factorization use a new arithmetic called 'clock arithmetic' which also helps in finding the last few digits of a large number without writing down all the digits. The book applies clock arithmetic to test whether a given number is prime or composite. We conclude by showing one of the great results of mathematics that a prime number which leaves a reminder of one after dividing by four can be written as the sum of two squares. However, a prime number which leaves a reminder of three after dividing by four cannot be written as the sum of two squares. Most of the results in the book are placed in an historical context"--
Download or read book Topology of Numbers written by Allen Hatcher and published by American Mathematical Society. This book was released on 2022-10-19 with total page 351 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book serves as an introduction to number theory at the undergraduate level, emphasizing geometric aspects of the subject. The geometric approach is exploited to explore in some depth the classical topic of quadratic forms with integer coefficients, a central topic of the book. Quadratic forms of this type in two variables have a very rich theory, developed mostly by Euler, Lagrange, Legendre, and Gauss during the period 1750–1800. In this book their approach is modernized by using the splendid visualization tool introduced by John Conway in the 1990s called the topograph of a quadratic form. Besides the intrinsic interest of quadratic forms, this theory has also served as a stepping stone for many later developments in algebra and number theory. The book is accessible to students with a basic knowledge of linear algebra and arithmetic modulo $n$. Some exposure to mathematical proofs will also be helpful. The early chapters focus on examples rather than general theorems, but theorems and their proofs play a larger role as the book progresses.

Download or read book Sums of Squares of Integers written by Carlos J. Moreno and published by CRC Press. This book was released on 2005-12-09 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
