Light enables us to see the world around us. Our sense of sight provides us with direct information about space and time, the physical arrangement of the world, and how it changes. This almost universal shared sensation of vision has led to a fascination with the nature and properties of light across the ages. But the light we see is just a small part of the whole spectrum of electromagnetic radiation, ranging from radio waves to gamma rays. In this Very Short Introduction Ian Walmsley discusses early attempts to explain light, and the development of apparently opposing particulate and wave theories by scientists such as Isaac Newton and Christiaan Huygens. He shows how light was recognized as an electromagnetic wave in the 19th century, and the development of the quantum mechanics view of wave-particle duality in the 20th century. He also describes the many applications of light, domestic and scientific, such as microwaves, DVDs, and lasers. We now use the whole range of electromagnetic radiation to peer both into the human body and deep into space. Turning to the future of optics, Walmsley concludes by looking at some of the most exciting new developments using quantum light sources in communications and computing.

Introduces readers to the basic properties of light -reflection and refraction, polarization, and interference- before moving on to how light is generated, its role in relativity, and quantum effects it exhibits.

Microscopy is a dynamic area of science, incorporating both basic classroom microscopes and sophisticated research style instruments that can be driven by light, electrons, or X-rays. The rate of advance in the area over the last 50 years has led to a number of technological advances. In this Very Short Introduction Terence Allen, an established expert on microscope techniques, describes the scientific principles behind the main forms of microscopy, and the exciting new developments in the field. Focusing on the main underlying principles, and introducing the power of what is achievable today using microscopes, Allen demonstrates how microscopy impinges on almost every aspect of our daily lives; from medical diagnosis to quality control in manufacture. Beginning with a brief history of the early stages of microscopy development, Allen then concludes with a comprehensive account of the diverse spectrum of microscopy available today.

Though he was a prolific writer and an original thinker of vast erudition, Jung lacked a gift for clear exposition and his ideas are less widely appreciated than they deserve. In this concise introduction, Anthony Stevens explains clearly the basic concepts of Jungian psychology: the collective unconscious, complex, archetype, shadow, persona, anima, animus, and the individuation of the Self. He examines Jung's views on such disparate subjects as myth, religion, alchemy, `sychronicity', and the psychology of gender differences, and he devotes separate chapters to the stages of life, Jung's theory of psychological types, the interpretation of dreams, the practice of Jungian analysis, and to the unjust allegation that Jung was a Nazi sympathizer. Finally, he argues that Jung's visionary powers and profound spirituality have helped many to find an alternative set of values to the arid materialism prevailing in Western society.

The study of materials is a major field of research that supports and drives innovation in technology. Using modern scientific techniques, materials scientists and engineers explore and manipulate materials, and create new ones with remarkable strength and extraordinary optical and electrical properties. In this Very Short Introduction, Christopher Hall looks at a wide range of materials, from steel, wood, and rubber, to gold, silicon, and graphene, describing how materials are used, how their properties arise from their internal structure, and how useful and novel things are made from them. He concludes by looking at how the global scale of materials consumption now threatens the goal of sustainability.

The eye is one of the most remarkable achievements of evolution, and has evolved up to 40 times in different parts of the animal kingdom. In humans, vision is the most important sense, and much of the brain is given over to the processing of visual information. In this Very Short Introduction, Michael Land describes the evolution of vision and the variety of eyes found in both humans and animals. He explores the evolution of colour vision in primates and the workings of the human eye, to consider how that contributes to our visual ability. He explains how we see in three dimensions and the basic principles of visual perception, including our impressive capacity for pattern recognition and the ability of vision to guide action.

What is learning? How does it take place? What happens when it goes wrong? The topic of learning has been central to the development of the science of psychology since its inception. Without learning there can be no memory, no language and no intelligence. Indeed it is rather difficult to imagine a part of psychology, or neuroscience, that learning does not touch upon. In this Very Short Introduction Mark Haselgrove describes learning from the perspective of associative theories of classical and instrumental conditioning, and considers why these are the dominant, and best described analyses of learning in contemporary psychology. Tracing the origins of these theories, he discusses the techniques used to study learning in both animals and humans, and considers the importance of learning for animal behaviour and survival.

From the first, telescopes have made dramatic revelations about the Universe and our place in it. Galileo's observations of the Moon's cratered surface and discovery of Jupiter's four big satellites profoundly altered the perception of the heavens, overturning a two-thousand year cosmology that held the Earth to be the centre of the Universe. Over the past century, the rapid development of computer technology and sophisticated materials allowed enormous strides in the construction of telescopes. Modern telescopes range from large Earth-based optical telescopes and radio arrays linking up across continents, to space-based telescopes capturing the Universe in infrared, ultraviolet, X-rays, and gamma rays. In combination, they have enabled us to look deep into the Universe and far back in time, capturing phenomena from galactic collisions to the formation of stars and planetary systems, and mapping the faint glow remaining from the Big Bang. In this Very Short Introduction, Dr. Geoff Cottrell describes the basic physics of telescopes, the challenges of overcoming turbulence and distortion from the Earth's atmosphere, and the special techniques used to capture X-rays and gamma rays in space telescopes. He explains the crucial developments in detectors and spectrographs that have enabled the high resolution achieved by modern telescopes, and the hopes for the new generation of telescopes currently being built across the world.

"How does the brain work? Michael O'Shea provides an accessible introduction to the key questions and current state of brain research, and shows that, though we know a surprising amount, we are still far from having a complete understanding. The topics he discusses range from how we sense things and how memories are stored, to the evolution of brains and nervous systems from primitive organisms, as well as altered mental states, brain-computer hybrids, and the future of brain research."--BOOK JACKET.
