A compact survey, at the elementary level, of some of the most important concepts of mathematics. Attention is paid to their technical features, historical development and broader philosophical significance. Each of the various branches of mathematics is discussed separately, but their interdependence is emphasised throughout. Certain topics - such as Greek mathematics, abstract algebra, set theory, geometry and the philosophy of mathematics - are discussed in detail. Appendices outline from scratch the proofs of two of the most celebrated limitative results of mathematics: the insolubility of the problem of doubling the cube and trisecting an arbitrary angle, and the Gödel incompleteness theorems. Additional appendices contain brief accounts of smooth infinitesimal analysis - a new approach to the use of infinitesimals in the calculus - and of the philosophical thought of the great 20th century mathematician Hermann Weyl. Readership: Students and teachers of mathematics, science and philosophy. The greater part of the book can be read and enjoyed by anyone possessing a good high school mathematics background.

The book is a new study that examines the contrasting extension of the Anglican Church to England's first two colonies, Ireland and Virginia in the 17th and 18th centuries. It discusses the national origins and educational experience of the ministers, the financial support of the state, and the experience and consequences of the institutions.

Do Less Better teaches leaders how to recognize the complexity and inefficiencies within their businesses and reveals how they can simplify and streamline through specialization and sacrifice. According to Bell, a company's willingness to focus on a particular vision or identity ensures viability and strengthens its competitive edge.

This specially curated collection features five reviews of current and key research on improving water management in crop cultivation.The first chapter focuses on site-specific variable rate irrigation systems utilised across agriculture and examines site-specific data acquisition and mining approaches, such as soil mapping and zone delineation.The second chapter considers the main deficit irrigation strategies used in agriculture to improve crop water productivity. It also explores the status of site-specific irrigation management and its role in minimizing agricultural water use.The third chapter reviews progress in winter wheat water management and water-use efficiency (WUE), drawing on long-term field experiments in the U.S. southern Great Plains. It discusses the key relationships between yield, evapotranspiration, WUE and best management practices.The fourth chapter considers the key techniques for improving rice water productivity through enhanced irrigation practices aiming to reduce irrigation water use in rice cultivation, such as the Alternate Wetting and Drying technique.The final chapter examines the main irrigation methods used in dryland sorghum production. It also reviews the relationship between soil properties and irrigation management.
