The terms 'liquid crystal' or 'liquid crystal display' (LCD) are recognized in the context of flat-screen televisions, but the properties and history of liquid crystals are little known. This book tells the story of liquid crystals, from their controversial discovery at the end of the nineteenth century, to their eventual acceptance as another state of matter to rank alongside gases, liquids, and solids. As their story unfolds, the scientists involved and their works are put into illuminating broader socio-political contexts. In recent years, liquid crystals have had a major impact on the display industry, culminating in the now widely available flat-screen televisions. This development is described in detail over three chapters, and the basic science behind it is explained in simple terms accessible to a general reader. New applications of liquid crystals in materials, biosystems, medicine, and technology are also explained. The authors' approach to the subject defines a new genre of popular science books. The historical background to the scientific discoveries is given in detail, and the personal communications between the scientists involved are explored. The book tells the story of liquid crystals, but it also shows that scientific discovery and exploitation relies on human interactions, and the social and political environments in which they operate.

Liquid crystals had a controversial discovery at the end of the 19th century but were later accepted as a 'fourth state' of matter, and finally used throughout the world in modern displays and new materials. This book explains the fascinating science in accessible terms, and puts it into social, political, and historical perspectives.

This book presents research contributions focussing on the introduction of contemporary physics topics – mainly, but not exclusively, quantum physics – into high school currciula. Despite the important advances and discoveries in quantum physics and relativity which have revolutionized our views of nature and our everyday lives, the presence of these topics in high school physics education is still lacking. In this book physics education researchers report on the teaching and learning of quantum physics from different perspectives and discuss the design and use of different pedagogical approaches and educational pathways. There is still much debate as to what content is appropriate at high school level as well what pedagogical approaches and strategies should be adopted to support student learning. Currently there is a greater focus on how to teach modern physics at the high school level rather than classical physics. However, teachers still lack experience and availability of appropriate teaching and learning materials to support the coherent integration of Quantum Physics in high school curricula. All of the 19 papers presented in this book discuss innovative approaches for enhancing physics education in schools.

Television is the most powerful system of images in the late 20th and early 21st centuries. Nonetheless, TV has attained only little philosophical attention so far, especially compared to other (visual) media such as film. This book looks at TV as what happens on the screen and beyond it; which is mainly the operation of switching images. It therefore proposes a new definition of TV as the first picture that can be switched on, off, and over, which stresses that TV is more tactile than visual. Through the operation of switching, TV figures the world from within and as the course of its figuration. This is grasped here by the term of “ontography”. Through the ongoing interlacing and bridging of “TV 1.0” (the image is being switched) and “TV 2.0” (the image is a switch), TV exponentially increases the production and circulation of images. It transforms the world and itself from an analogue state to a digital one and from central perspectivism to pluri-perspective. In terms of time, through switching and the switch, it develops and reworks new temporal orderings, such as instantaneity, synchronicity, flow, and seriality. TV makes its own history. In space, it creates a mediasphere as its habitat and hence new forms of being-in-the-world, of proximity and distance, and scale. Anthropologically, it works on what a subject and an object is, on what makes the human being, and ontographically, how it is possible that there is something at all instead of nothing: through switch-images.

What would our world today be like without inventions like tarmac, aspirin, liquid crystals, and barbed wire? This guide shows how patents and the inventions they describe have shaped the 21st century. It gives us insights into the inventions, big and small, that have had huge impacts, many unexpected, on multiple spheres of our lives, from popular culture and entertainment, to global health, to transportation, to the waging of war. It features patent documents that date from the mid-19th century to the present. Patent documents describe inventions and represent an accurate and rich source of information about the history and current state of modern technology, as patents are examined and their accuracy can be challenged. The subject matter covers many technical areas. Patents discussed include, for example, Morse code, the diode, triode, transistors, television, frozen foods, ring-pull for soft drink cans, board games such as Monopoly, gene editing, metamaterials, MRI, computerised tomography, insulin, and monoclonal antibodies such as Herceptin. The text is illustrated with drawings adapted from the original patent documents. Patent numbers are included to allow interested readers to trace the documents. Inventions described in the patents are placed in historical perspective. For example, the book discusses the role of the cavity magnetron and radar in World War II, and the influence of the diode on the development of broadcasting at the beginning of the 20th century.

Introduction to Liquid Crystals: Chemistry and Physics, Second Edition relies on only introductory level chemistry and physics as the foundation for understanding liquid crystal science. Liquid crystals combine the material properties of solids with the flow properties of fluids. As such they have provided the foundation for a revolution in low-power, flat-panel display technology (LCDs). In this book, the essential elements of liquid crystal science are introduced and explained from the perspectives of both the chemist and physicist. This new edition relies on only introductory level physics and chemistry as the foundation for understanding liquid crystal science and is, therefore, ideal for students and recent graduates. Features Introduces and explains the essential elements of liquid crystal science, including discussion of how liquid crystals have been utilized for innovative and important applications. New to this edition are over 300 figures, 90 end-of chapter exercises, and an increased scope that includes recent developments. Combines the knowledge of two eminent scientists in the field; they have fully updated and expanded the text to cover undergraduate/graduate course work as well as current research in what is now a billion-dollar industry. Immerses the reader in the vocabulary, structures, data, and kinetic models, rapidly building up an understanding of the theories and models in current use. Begins with a historical account of the discovery of liquid crystals and continues with a description of how different phases are generated and how different molecular architectures affect liquid crystal properties.

While it is responsible for today’s abundance of flat screens—on televisions, computers, and mobile devices—most of us have only heard of it in the ubiquitous acronym, LCD, with little thought as to exactly what it is: liquid crystal. In this book, Esther Leslie enlightens us, offering an accessible and fascinating look at—not a substance, not a technology—but a wholly different phase of matter. As she explains, liquid crystal is a curious material phase that organizes a substance’s molecules in a crystalline form yet allows them to move fluidly like water. Observed since the nineteenth century, this phase has been a deep curiosity to science and, in more recent times, the key to a new era of media technology. In between that time, as Leslie shows, it has figured in cultural forms from Romantic landscape painting to snow globes, from mountaineering to eco-disasters, and from touchscreen devices to DNA. Expertly written but accessible, Liquid Crystals recounts the unheralded but hugely significant emergence of this unique form of matter.
