Throughout history scepticism and the urge to question accepted truths has been a powerful force for change and growth. Today, as we are bombarded by adverts, scientific studies praising the latest superfoods, and political rhetoric, a healthy amount of scepticism is widely encouraged. But when is such scepticism legitimate - for example, as a driver of new ideas - and when is it problematic? And what role might adopting a sceptical outlook play in leading an intellectually virtuous life? In this Very Short Introduction Duncan Pritchard explores both the advantages of scepticism, in challenging outdated notions, and also how it can have unhelpful social consequences, in generating distrust. He considers the role of scepticism at the source of contemporary social and political movements such as climate change denial, post-truth politics, and fake news. Pritchard also examines the philosophical arguments for a radical form of scepticism which maintains that knowledge is impossible, and explores some of the main responses to these arguments. Finally, he considers the part scepticism might play in applying better thinking and learning to achieve a more meaningful life.

Tom McLeish delves into the growing field of soft matter - the study of materials such as polymers, colloids, liquid crystals, and foams. Looking beneath their appearance to their inner structure, he discusses their shared physical properties, the principle of Brownian Motion that underlies all soft matter, and the applications of these materials.

Born of the desire to understand the workings of motions of the heavenly bodies, trigonometry gave the ancient Greeks the ability to predict their futures. Most of what we see of the subject in school comes from these heavenly origins; 15th century astronomer Regiomontanus called it "the foot of the ladder to the stars". In this Very Short Introduction Glen Van Brummelen shows how trigonometry connects mathematics to science, and has today become an indispensable tool in predicting cyclic patterns like animal populations and ocean tides. Its historical journey through major cultures such as medieval India and the Islamic World has taken it through disciplines such as geography and even religious practice. Trigonometry has also been a major player in the most startling mathematical developments of the modern world. Its interactions with the concept of infinity led to Taylor and Fourier series, some of the most practical tools of modern science. The birth of complex numbers led to a shocking union of exponential and trigonometric functions, creating the most beautiful formulas and powerful modelling tools in science. Finally, as Van Brummelen shows, trigonometry allows us to explore the strange new worlds of non-Euclidean geometries, opening up bizarre possibilities for the shape of space itself. And indeed, one of those new geometries - spherical - takes us full circle back to ancient Greek astronomers and European navigators, who first used it to chart their ways across the heavens and the earth.

Most people are familiar with the dodo and the dinosaur, but extinction has occurred throughout the history of life, with the result that nearly all the species that have ever existed are now extinct. Today, species are disappearing at an ever increasing rate, whilst past losses have occurred during several great crises. Issues such as habitat destruction, conservation, climate change, and, during major crises, volacanism and meteorite impact, can all contribute towards the demise of a group. In this Very Short Introduction, Paul B. Wignall looks at the causes and nature of extinctions, past and present, and the factors that can make a species vulnerable. Summarising what we know about all of the major and minor exctinction events, he examines some of the greatest debates in modern science, such as the relative role of climate and humans in the death of the Pleistocene megafauna, including mammoths and giant ground sloths, and the roles that global warming, ocean acidification, and deforestation are playing in present-day extinctions ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area.

What is matter? Matter is the stuff from which we and all the things in the world are made. Everything around us, from desks, to books, to our own bodies are made of atoms, which are small enough that a million of them can fit across the breadth of a human hair. Inside every atom is a tiny nucleus and orbiting the nucleus is a cloud of electrons. The nucleus is made out of protons and neutrons, and by zooming in further you would find that inside each there are even smaller particles, quarks. Together with electrons, the quarks are the smallest particles that have been seen, and are the indivisible fundamental particles of nature that have existed since the Big Bang, almost 14 billion years ago. The 92 different chemical elements that all normal matter is made from were forged billions of years ago in the Big Bang, inside stars, and in violent stellar explosions. This Very Short Introduction takes us on a journey from the human scale of matter in the familiar everyday forms of solids, liquids, and gases to plasmas, exotic forms of quantum matter, and antimatter. On the largest scales matter is sculpted by gravity into planets, stars, galaxies, and vast clusters of galaxies. All the matter that that we normally encounter however constitutes only 5% of the matter that exists. The remaining 95% comes in two mysterious forms: dark matter, and dark energy. Dark matter is necessary to stop the galaxies from flying apart, and dark energy is needed to explain the observed acceleration of the expansion of the universe. Geoff Cottrell explores the latest research into matter, and shows that there is still a lot we don't know about the stuff our universe is made of.

Somewhere between 1910 and 1970, architecture changed. Now that modern architecture has become familiar (sometimes celebrated, sometimes vilified), it's hard to imagine how novel it once seemed. Expensive buildings were transformed from ornamental fancies which referred to the classical and medieval pasts into strikingly plain reflections of novel materials, functions, and technologies. Modern architecture promised the transformation of cities from overcrowded conurbations characterised by packed slums and dirty industries to spacious realms of generous housing and clean mechanised production set in parkland. At certain times and in certain cultures, it stood for the liberation of the future from the past. This Very Short Introduction explores the technical innovations that opened-up the cultural and intellectual opportunities for modern architecture to happen. Adam Sharr shows how the invention of steel and reinforced concrete radically altered possibilities for shaping buildings, transforming what architects were able to imagine, as did new systems for air conditioning and lighting. While architects weren't responsible for these innovations, they were among the first to appreciate how they could make the world look and feel different, in connection with imagery from other spheres like modern art and industrial design. Focusing on a selection of modern buildings that also symbolize bigger cultural ideas, Sharr discusses what modern architecture was like, why it was like that, and how it was imagined. Considering the work of some of the historians and critics who helped to shape modern architecture, he demonstrates how the field owes as much to its storytellers as to its buildings.

Engineering is part of almost everything we do - from the water we drink and the food we eat, to the buildings we live in and the roads and railways we travel on. This book explores the nature and practice of engineering, its history, its scope, and its relationship with art, science and technology.

In this Very Short Introduction, Mark Maslin looks at all aspects of climate, from the physical and chemical factors that drive it and how climate differs from weather, to how climate has affected human settlements and the cyclic features of it. He ends with a look at climate change and our current approaches to solving it.

Very Short Introductions: Brilliant, Sharp, Inspiring Imagination: A Very Short Introduction explores imagination as a cognitive power and an essential dimension of human flourishing, demonstrating how imagination plays multiple roles in human cognition and shapes humanity in profound ways. Examining philosophical, evolutionary, and literary perspectives on imagination, the author shows how this facility, while potentially distorting, both frees us from immediate reality and enriches our sense of it, making possible our experience of a meaningful world. Long regarded by philosophers as an elusive and mysterious capacity of the human mind, imagination has been the subject of extraordinary ambivalence, described as both dangerous and divine, as merely peripheral to rationality and as essential to all thinking. Drawing on philosophy, aesthetics, literary and cognitive theory as well as the human sciences, this book engages the dramatic conceptual history of imagination together with contemporary explanations of its role in cognition to explain its importance in everyday life as well as the exquisite creativity of the arts, scientific discovery, and invention. Engaging examples from cave paintings to modern painting, performance art to pop art, physics to phenomenology, technological inventions to literary worlds, the Nazca geoglyphs to dramatic theatre, poetry, and jazz improvisation, the author illuminates with clarity and vision the philosophy of imagination and the stakes of its involvement in human thinking.
