The 20th century saw a remarkable upsurge of research on drugs, with major advances in the treatment of bacterial and viral infections, heart disease, stomach ulcers, cancer, and metal illnesses. These, along with the introduction of the oral contraceptive, have altered all of our lives. There has also been an increase in the recreational use and abuse of drugs in the Western world. This Very Short Introduction, in its second edition, gives a nontechnical account of how drugs work in the body.

If you move at high speed, time slows down, space squashes up, and you get heavier. Travel fast enough and you could weigh as much as a jumbo jet, be flattened thinner than a CD without feeling a thing - and live forever! As for the angles of a triangle, they do not always have to add up to 180 degrees. And then, of course, there are black holes. These are but a few of the extraordinary consequences of Einstein's theory of relativity.

Taking a thematic rather than strictly chronological approach, W. F. Bynum, explores the key turning points in the history of Western medicine - such as the first surgical procedures, the advent of hospitals, the introduction of anesthesia, X-Rays, vaccinations, and many other innovations, as well as the rise of experimental medicine. The book also explores Western medicine's encounters with Chinese and Indian medicine, as well as nontraditional treatments such as homeopathy, chiropractic, and other alternative medicines.

In this Very Short Introduction, Gerhard L. Weinberg provides an introduction to the origins, course, and impact of the war on those who fought and the ordinary citizens who lived through it.

For many, the terrorist attacks of September 2001 changed the face of the world, pushing terrorism to the top of political agendas, and leading to a series of world events, including the war in Iraq and the invasion of Afghanistan. The recent terror attacks in various European cities have shown that terrorism remains a crucial issue today. Charting a clear path through the efforts to understand and explain modern terrorism, Charles Townshend examines the historical, ideological, and local roots of terrorist violence.

The laws of thermodynamics drive everything that happens in the universe. From the sudden expansion of a cloud of gas to the cooling of hot metal - everything is moved or restrained by four simple laws. This powerful and compact introduction explains what these four laws are and how they work, using accessible language and virtually no mathematics.

Enzymes are the astonishing tiny molecular machines that make life possible. Each one of these small proteins speeds up a single chemical reaction inside a living organism many millionfold. Working together, teams of enzymes carry out all the processes that collectively we recognize as life, from making DNA to digesting food. This Very Short Introduction explains the why and the how of speeding up these reactions - catalysis - before going on to reveal how we have evolved these catalysts of such extraordinary power and exquisite selectivity.

This second edition of the Very Short Introduction on ethics has revised and updated aspects of the original to reflect changing times and mores.

In this Very Short Introduction, Simon Horobin investigates how we have arrived at the English we know today and celebrates the way new speakers and new uses mean that it continues to adapt. Engaging with contemporary concerns about correctness, Horobin considers whether such changes are improvements or evidence of slipping standards.

The aim of this book is to explain, carefully but not technically, the differences between advanced, research-level mathematics and the sort of mathematics we learn at school. The most fundamental differences are philosophical, and listeners of this book will emerge with a clearer understanding of paradoxical-sounding concepts such as infinity, curved space, and imaginary numbers. The first few chapters are about general aspects of mathematical thought.

In this Very Short Introduction, Nick Jenkins explores our historic investment in the exploitation of fossil energy resources and their current importance, and discusses the implications of our increasing rate of energy use. He considers the widespread acceptance by scientists and policy makers that our energy systems must reduce emissions of CO2 and other greenhouse gases, and looks forward to the radical changes in fuel technology that will be necessary to continue to provide energy supplies in a sustainable manner, and extend access across the developing world.

Logic is often perceived as having little to do with the rest of philosophy, and even less to do with real life. In this lively and accessible introduction, Graham Priest shows how wrong this conception is. He explores the philosophical roots of the subject, explaining how modern formal logic deals with issues ranging from the existence of God and the reality of time to paradoxes of probability and decision theory. Along the way, the basics of formal logic are explained in simple, non-technical terms, showing that logic is a powerful and exciting part of modern philosophy.

The concept of law lies at the heart of our social and political life. Legal philosophy, or jurisprudence, explores the notion of law and its role in society, illuminating its meaning and its relation to the universal questions of justice, rights, and morality.

Psychology is part of everyone's experience: It influences the way we think about everything from education and intelligence, to relationships and emotions, advertising and criminality. People readily behave as amateur psychologists, offering explanations for what people think, feel, and do. But what exactly are psychologists trying to do? What scientific grounding do they have for their approach? This Very Short Introduction explores some of psychology's leading ideas and their practical relevance.

Few would question that Albert Camus (1913-1960), novelist, playwright, philosopher and journalist, is a major cultural icon. His widely quoted works have led to countless movie adaptions, graphic novels, pop songs, and even t-shirts.

This Very Short Introduction audiobook describes what psychologists have discovered about how and why people differ in their thinking powers. Drawing on largescale data, Ian Deary considers how many types of intelligence there are and how intelligence changes with age.

In this fascinating book, Michael O'Shea provides a non-technical introduction to the main issues and findings in current brain research, and gives a sense of how neuroscience addresses questions about the relationship between the brain and the mind.
