This book is open access under a CC BY license. This interdisciplinary book contains 22 essays and interventions on rest and restlessness, silence and noise, relaxation and work. It draws together approaches from artists, literary scholars, psychologists, activists, historians, geographers and sociologists who challenge assumptions about how rest operates across mind, bodies, and practices. Rest's presence or absence affects everyone. Nevertheless, defining rest is problematic: both its meaning and what it feels like are affected by many socio-political, economic and cultural factors. The authors open up unexplored corners and experimental pathways into this complex topic, with contributions ranging from investigations of daydreaming and mindwandering, through histories of therapeutic relaxation and laziness, and creative-critical pieces on lullabies and the Sabbath, to experimental methods to measure aircraft noise and track somatic vigilance in urban space. The essays are grouped by scale of enquiry, into mind, body and practice, allowing readers to draw new connections across apparently distinct phenomena. The book will be of interest to students and scholars across a range of disciplines in the social sciences, life sciences, arts and humanities.

James O. Wilkes has updated his expert hands-on fluid mechanics tutorial with a complete introduction to the popular COMSOL Multiphysics 5.2 software package, and ten new COMSOL 5.2 examples.   Building on the text that earned Choice Magazine’s prestigious Outstanding Academic Titles award, Wilkes offers masterful coverage of key fluid mechanics topics including computing turbulent flows, bubble motion, two-phase flow, fluidization, microfluidics, electro-kinetic flow effects, and computational fluid dynamics. Throughout, he presents more than 300 problems of incrementally greater difficulty, helping students build mastery through realistic practice.   Wilkes starts with a macroscopic approach, providing a solid foundation for sizing pumps and operating laboratory and field scale equipment. The first four chapters derive equations needed to size chemical plant equipment, including pipes in packed beds, pumping installation, fluid flow measurement, filtration, and cyclone separation. Next, he moves to a microscopic approach, introducing key principles for modeling more advanced systems and solving industry or graduate-level problems. These chapters start with a simple derivation of the Navier-Stokes equation (NSE), and then introduce assumptions for various flow geometries, helping students reduce equations for easy solution -- analytically, or numerically with COMSOL. Updated COMSOL examples include boundary layer flow, non-Newtonian flow, jet flow, lathe flow, lubrication, momentum diffusion, flow through an orifice plate parallel plate flow, turbulent flow, and more.

Bodypopping Belgians and bicycle couriers populate a world of public fountains and archaeological debris in this original and eclectic collection by James Wilkes. Weather A System includes poems, found text, scripts, ephemera and imaginary reviews; subversive broadcasts that cut through the 'civil drizzle' of contemporary life. Wilkes' work excavates the present, looting and salvaging to craft an innovative, playful and multi-dimensional poetics. Weather A System captures shifts of weather, power and fashion: an energetic and darkly witty intervention in an eroded culture.
