The phrase "the meaning of life" for many seems a quaint notion fit for satirical mauling by Monty Python or Douglas Adams. But in this spirited Very Short Introduction, famed critic Terry Eagleton takes a serious if often amusing look at the question and offers his own surprising answer.

This Very Short Introduction discusses the key concepts of biochemistry, as well as the historical figures in the field and the molecules they studied, before considering the current science and innovations in the field, and the interaction between biochemistry, biotechnology, and synthetic biology.

The Cold War dominated international life from the end of World War II to the fall of the Berlin Wall in 1989. But how did the conflict begin? Why did it move from its initial origins in Postwar Europe to encompass virtually every corner of the globe? And why, after lasting so long, did the war end so suddenly and unexpectedly? Robert McMahon considers these questions and more, as well as looking at the legacy of the Cold War and its impact on international relations today.

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.

By the time the First World War ended in 1918, eight million people had died in what had been perhaps the most apocalyptic episode the world had known. This Very Short Introduction audiobook provides a concise and insightful history of the Great War - from the state of Europe in 1914, to the role of the US, the collapse of Russia, and the eventual surrender of the Central Powers.

From the contours of coastlines to the outlines of clouds, and the branching of trees, fractal shapes can be found everywhere in nature. In this Very Short Introduction, Kenneth Falconer explains the basic concepts of fractal geometry, which produced a revolution in our mathematical understanding of patterns in the 20th century, and explores the wide range of applications in science, and in aspects of economics.

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.

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.

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.

We make choices all the time - about how to spend our money, about how to spend our time, about what to do with our lives. And we are also constantly judging the decisions other people make as rational or irrational. But what kind of criteria are we applying when we say that a choice is rational? What guides our own choices, especially in cases where we don't have complete information about the outcomes? What strategies should be applied in making decisions which affect a lot of people, as in the case of government policy?

This Very Short Introduction presents the field of fluid mechanics by focusing on the underlying physical ideas and using everyday phenomena to demonstrate them, from dripping taps to swimming ducks. Eric Lauga shows how this set of fundamental physical concepts can be applied to a wide range of flow behaviors and highlights the role of fluid motion in both the natural and industrial worlds. This book also considers future applications of fluid mechanics in science.

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.

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.

Was love invented by European poets in the Middle Ages, or is it part of human nature? Will winning the lottery really make you happy? Is it possible to build robots that have feelings? In this Very Short Introduction audiobook, Dylan Evans explores these and many other intriguing questions in this guide to the latest thinking about the emotions.

The process by which nations escape poverty and achieve economic and social progress has been the subject of extensive examination for hundreds of years. The notion of development itself has evolved from an original preoccupation with incomes and economic growth to a much broader understanding of development. In this Very Short Introduction, Ian Goldin considers the contributions that education, health, gender, equity, and other dimensions of human well-being make to development.

Although there are many kinds of love, erotic love has been celebrated in art and poetry as life's most rewarding and exalting experience, worth living and dying for and bringing out the best in ourselves. And yet it has excused, and even been thought to justify, the most reprehensible crimes.

International security is never out of the headlines. War and peace, military strategy, the proliferation of nuclear weapons and revisionist states remain central to the discussion, but concerns such as climate change, migration, poverty, health, and international terrorism have complicated the field. So what really matters: the traditional prioritization of state security or the security needs of individuals, humanity, and the biosphere?

More than ever before, the Renaissance stands out as one of the defining moments in world history. Between 1400 and 1600, European perceptions of society, culture, politics, and even humanity itself emerged in ways that continue to affect not only Europe but the entire world. In this wide-ranging exploration of the Renaissance, Jerry Brotton shows the period as a time of unprecedented intellectual excitement, cultural experimentation, and interaction on a global scale, alongside a darker side of religion, intolerance, slavery, and massive inequality of wealth and status.

With lively writing and illuminating examples, David Caplan argues that two characteristics mark the vast, contentious literature. On the one hand, several of America's major poets and critics claim that America needs a poetry equal to the country's distinctiveness. They advocate for novelty and for a break with what is perceived to be outmoded and foreign.
