A Very Short Introduction

Algebra marked the beginning of modern mathematics, moving it beyond arithmetic, which involves calculations featuring given numbers, to problems where some quantities are unknown. Now, it stands as a pillar of mathematics, underpinning the quantitative sciences, both social and physical.

Environmental ethics is a relatively new branch of philosophy, which studies the values and principles involved in combatting environmental problems such as pollution, loss of species and habitats, and climate change. As our environment faces evermore threats from human activities these core issues are becoming increasingly important.

Identity has become one of the most widely used terms today, appearing in many different contexts. Anything and everything has an identity, and identity crises have become almost equally pervasive. Yet "identity" is extremely versatile, meaning different things to different people and in different scientific disciplines. To many its meaning seems self-evident, since its various uses share common features, so often the term is used without a definition of what, exactly, is meant by it. This provokes the core question: What exactly is identity?

Critical theory emerged in the 1920s from the work of the Frankfurt School, the circle of German-Jewish academics who sought to diagnose – and, if at all possible, cure – the ills of society, particularly fascism and capitalism. In this book, Stephen Eric Bronner provides sketches of leading representatives of the critical tradition (such as George Lukács and Ernst Bloch, Theodor Adorno and Walter Benjamin, Herbert Marcuse and Jurgen Habermas) as well as many of its seminal texts and empirical investigations.

We live in a society which is increasingly interconnected, in which communication between individuals is mostly mediated via some electronic platform, and transactions are often carried out remotely. In such a world, traditional notions of trust and confidence in the identity of those with whom we are interacting, taken for granted in the past, can be much less reliable. Biometrics – the scientific discipline of identifying individuals by means of the measurement of unique personal attributes – provides a reliable means of establishing or confirming an individual's identity. These attributes include facial appearance, fingerprints, iris patterning, the voice, the way we write, or even the way we walk. The new technologies of biometrics have a wide range of practical applications, from securing mobile phones and laptops to establishing identity in bank transactions, travel documents, and national identity cards.

A renowned critic, biographer, and Shakespeare scholar, Jonathan Bate provides in this Very Short Introduction a lively and engaging overview of the literature that Jorge Luis Borges called "the richest in the world." From the medieval "Hymn of Caedmon" to George Orwell's "Why I Write," from Jane Austen to Ian McEwan, and from Winnie the Pooh to Dr. Johnson, this brilliant, compact survey stretches across the centuries, exploring the major literary forms (poetry, novel, drama, essay and more), the many histories and theories of the very idea of literature, and the role of writers in shaping English, British, and post-imperial identities.

Children's literature takes many forms - works adapted for children in antiquity, picture books and pop-ups - and now includes the latest online games and eBooks. This vast and amorphous subject is both intimately related to other areas of literary and cultural investigation but also has its own set of concerns, issues and challenges.

Autobiography is one of the most popular of written forms. From Casanova to Benjamin Franklin to the Kardashians, individuals throughout history have recorded their own lives and experiences. These personal writings are central to the work of literary critics, philosophers, historians, and psychologists, who have found in autobiographies from across the centuries not only an understanding of the ways in which lives have been lived, but the most fundamental accounts of what it means to be a self in the world.

Many people regard Hegel's work as obscure and extremely difficult, yet his importance and influence are universally acknowledged. Professor Singer eliminates any excuse for remaining ignorant of the outlines of Hegel's philosophy by providing a broad discussion of his ideas and an account of his major works.

Geophysics is the physics of the Earth. Central to the Earth Sciences today, it encompasses areas such as seismology, volcanism, plate tectonics, gravitational anomalies, and the Earth's magnetic field (present and past, as captured in rocks), all of which give clues to both the structure and the working of the Earth.
