A wide-ranging illustrated history of transparency as told through the evolution of the glass window Transparency is a mantra of our day. It is key to the Western understanding of a liberal society. We expect transparency from, for instance, political institutions, corporations, and the media. But how did it become such a powerful—and global—idea? From ancient glass to Apple's corporate headquarters, this book is the first to probe how Western people have experienced, conceptualized, and evaluated transparency. Daniel Jütte argues that the experience of transparency has been inextricably linked to one element of Western architecture: the glass window. Windows are meant to be unnoticed. Yet a historical perspective reveals the role that glass has played in shaping how we see and interpret the world. A seemingly “pure” material, glass has been endowed, throughout history, with political, social, and cultural meaning, in manifold and sometimes conflicting ways. At the same time, Jütte raises questions about the future of vitreous transparency—its costs in terms of visual privacy but also its ecological price tag in an age of accelerating climate change.

The interaction of radiation with matter is a fundamental process in the universe; in particular, the absorption and scattering of radiation by matter (the opacity) govern the formation, evolution, and structure of stars and planets. But opacity is also important in many terrestrial applications in which radiation is the dominant means of energy transfer, such as controlled nuclear-fusion, laser ablation, atmospheric entry and reentry, and the'greenhouse'effect. This book covers all aspects of opacity and equations of state for plasmas, gases, vapors, and dust and emphasizes the continuous transformation of phases and molecular compositions with changing density and temperature under conditions of local thermodynamic equilibrium (LTE) while preserving the basic abundances of the chemical elements in a mixture.
