• Sommario/riassunto: This book explores implications for applied linguistics of recent developments in technologies used in second language teaching and assessment, language analysis, and language use. Focusing primarily on English language learning, the book identifies significant areas of interplay between technology and applied linguistics, and it explores current perspectives on perennial questions such as how theory and research on second language acquisition can help to inform technology-based language learning practices, how the multifaceted learning accomplished through technology can be evaluated, and how theoretical perspectives can offer insight on data obtained from research on interaction with and through technology. The book illustrates how the interplay between technology and applied linguistics can amplify and expand applied linguists’ understanding of fundamental issues in the field. Through discussion of computer-assisted approaches for investigating second language learning tasks ; and assessment, it illustrates how technology can be used as a tool for applied linguistics research.

• Sommario/riassunto: This book opens with an axiomatic description of Euclidean and non-Euclidean geometries. Euclidean geometry is the starting point to understand all other geometries and it is the cornerstone for our basic intuition of vector spaces. The generalization to non-Euclidean geometry is the following step to develop the language of Special and General Relativity. These theories are discussed starting from a full geometric point of view. Differential geometry is presented in the simplest way and it is applied to describe the physical world. The final result of this construction is deriving the Einstein field equations for gravitation and spacetime dynamics. Possible solutions, and their physical implications are also discussed: the Schwarzschild metric, the relativistic trajectory of planets, the deflection of light, the black holes, the cosmological solutions like de Sitter, Friedmann-Lemaître-Robertson-Walker, and Gödel ones. Some current problems like dark energy are also scketched. The book is self-contained and includes details of all proofs. It provides solutions or tips to solve problems and exercises. It is designed for undergraduate students and for all readers who want a first geometric approach to Special and General Relativity.
