This path-breaking book argues that practices of the sacred are constitutive of modern secular politics. Following a tradition of enquiry in anthropology and political theory, it examines how limit situations shape the political imagination and collective identity. As an experiential and cultural fact, the sacred emerges within, and simultaneously transcends, transgressive dynamics such as revolutions, wars or globalisation. Rather than conceive the sacred as a religious doctrine or a metaphysical belief, Wydra examines its adaptive functions as origins, truths and order which are historically contingent across time and transformative of political aspirations. He suggests that the brokenness of political reality is a permanent condition of humanity, which will continue to produce quests for the sacred, and transcendental political frames. Working in the spirit of the genealogical mode of enquiry, this book examines the secular sources of political theologies, the democratic sacred, the

The ocean is opaque to electromagnetic radiation and transparent to low frequency sound, so acoustical methodologies are an important tool for sensing the undersea world. Stochastic sound-speed fluctuations in the ocean, such as those caused by internal waves, result in a progressive randomisation of acoustic signals as they traverse the ocean environment. This signal randomisation imposes a limit to the effectiveness of ocean acoustic remote sensing, navigation and communication. Sound Propagation through the Stochastic Ocean provides a comprehensive treatment of developments in the field of statistical ocean acoustics over the last 35 years. This will be of fundamental interest to oceanographers, marine biologists, geophysicists, engineers, applied mathematicians, and physicists. Key discoveries in topics such as internal waves, ray chaos, Feynman path integrals, and mode transport theory are addressed with illustrations from ocean observations. The topics are presented at an approac
