This new study explores the development of the window, showing how it both transformed human experience by increasing access to light and air and changed our perception of architectural space Christopher Masters celebrates the multiple roles of the window in architecture by providing engaging commentaries on over 80 exceptional buildings of all types, both ancient and modern. The unique selection ranges from the Pantheon in Rome, the Hagia Sophia in Istanbul, Sainte-Chapelle in Paris, and the Katsura Imperial Villa in Kyoto to Walter Gropius's Bauhaus in Dessau, Eero Saarinen's TWA Terminal in New York, Jean Nouvel's Louvre Abu Dhabi, and Dorte Mandrup's Icefjord Centre in Greenland. Featuring more than 100 superb photographs, this is an intriguing and accessible survey of a formerly neglected subject in architectural history.

A window provides access to two of life's essentials, light and air, but it is more than just a means to an end. Windows also have symbolic, expressive and architectural qualities that have for centuries inspired some of the world's greatest artists. In this engaging new study, Christopher Masters celebrates the multiple roles of the window in art through five key themes, from the window as a status symbol to its use as a provider of physical and spiritual illumination; from its employment as a literal window on the world outside the confines of a room to its function as a mirror, reflecting the emotions of the artist or the individuals depicted; and finally to the immense architectural variety of windows that animate interior and exterior scenes throughout Western painting. With superb reproductions of 90 works by major artists from Giotto to Banksy, and spirited analysis of the paintings' meanings, this is a remarkable exploration of an important but hitherto neglected subject in art history.

A most striking, design-led reference book, A to Z Great Modern Artists features artist and graphic designer Andy Tuohy's portraits of 52 key modern artists, rendered in each artist's own characteristic style - including Aleksandr Rodchenko in his constructivist poster style, Andy Warhol as a classic repeat print, and Barbara Hepworth illustrated to resemble one of her distinctive bronze and rod sculptures. With expert text by art historian Christopher Masters, each artist's entry includes a summary of the essential things you need to know about the artist; their biographical details, why they're so significant, where you can find their works today, and a surprising fact about them plus reproductions of key works. Whether you're already an art expert, or looking for a helpful cheat to navigating around a gallery, you'll love this stunning and intelligent guide to global artists of the modern age.

Salvador Dali (1904-89) was one of the most controversial and paradoxical artists of the twentieth century. A painter of considerable virtuosity, he used a traditional illusionistic style to create disturbing images filled with references to violence, death, cannibalism and bizarre sexual practices, from the extraordinary limp watches in The Persistence of Memory to the gruesome monster in Soft Construction with Boiled Beans: Premonition of Civil War and the fetishistic lobster in the famous Lobster Telephone. Born in Figueras, Spain, Dali was initially influenced by Impressionism and Cubism, but subsquently became involved with the Surrealists, the most revolutionary artists of the time. They regarded his paintings as revealing the normally hidden world of the unconscious. Indeed the Surrealists' leader, Andre Breton, remarked: "It is perhaps with Dali that for the first time the windows of the mind are opened fully wide". However, Breton later expelled him from the group for this right-wing sympathies and derided his commercial success in the United States, calling him 'Avida Dollars'. Dali's response was equally curt: " The difference between me and the Surrealists is that I am a Surrealist". Not restricting his interests to painting, Dali wrote three autobiographies, designed sets and costumes for a play by his friend Federico Garcia Lorca and collaborated with Luis Bunuel in the film Un Chien andalou, a medium which proved particularly apt for his provocative imagery.

Soluble catalysts are used extensively in many branches of chemistry and are indeed a vital constituent of many natural processes. They find wide application throughout the chemical industry where they assist in the production of several million tonnes of chemicals each year. Since homogeneous systems, especially those incorporating transition metals, often function effectively under milder conditions than their heterogeneous counterparts, they are becoming increasingly important at a time when the chemical industry in particular, and society in general, is seeking ways of conserving energy and of making the best possible use of available resources. My principal objective in- writing this book is to engender sufficient enthusiasm for, and knowledge of, the subject in the reader that he or she will be encouraged to begin, or continue, to make their own contribution to advancing our knowledge of homogeneous catalysis. After attempting to acquaint the reader with some of the ground rules I have tried to describe the present scope, and the future potential, of this fascinating field of chemistry by drawing both on academic and on industrial data sources. This approach stems from a personal conviction that future progress could be considerably hastened by a more meaningful dialogue between chemists working both in industrial and in academic research institutions. Wherever possible, examples of the commercial application of homogeneous catalyst systems have been included and no attempt has been made in any way to disguise the many unresolved questions and exciting challenges which still pervade this rapidly developing area.

Another adventure for everyone's favourite Time Lord. The Doctor (Tom Baker), Sarah and Harry land on space station Nerva, where the chosen few of the human race are in suspended animation, awaiting the call to revive. However, an insectoid alien life form known as the Wirrn has infiltrated the Ark and cut through the humans' alarm clock. The Wirrn now intend to use the sleepers as the hosts for their hatchings and claim the Earth as their own.
