An engrossing set of three lectures on the physics behind formation of soop bubbles. Also translated in Hindi, Marathi and Tamil
This excellent primer and classic work on the topic of soap bubbles and films employs simple experiments to establish a practical basis for the existence and function of surface tension and energy minimization. Experiments require only soap, straws, and bits of rubber to impart profound fundamental concepts related to fluids. 83 illustrations. 1911 edition.
The Morals of Measurement is a contribution to the social histories of quantification and electrical technology in nineteenth-century Britain, Germany and France. It shows how the advent of commercial electrical lighting stimulated the industrialization of electrical measurement from a skilled labour-intensive activity to a mechanized practice. Challenging traditional accounts that focus on the metrological standards used in measurement, this book shows the central importance of trust when measurement was undertaken in an increasingly complex division of labour. Alongside ambiguities about the very nature of measurement and the respective responsibilities of humans and technologies in generating error-free numbers, the book also addresses controversies over the changing identity of the measurer through the themes of body, gender and authorship. The reader will gain fresh insights into a period when measurement was widely treated as the definitive means of gaining knowledge of the world.
Ordinary foams such as the head of a glass of beer and more exotic ones such as solid metallic foams raise many questions for the physicist and have attracted a substantial research community in recent years. The present book describes the results of extensive experiments, computer simulations, and theories in an authoritative yet informal style, making ample use of illustrations and photographs. As an introduction to the whole field of the physics of foams it puts a strong emphasis on liquids while also including solid foams. Simple, idealized models are adopted and their consequences explored. Specific topics include: structure, drainage, rheology, conductivity, and coarsening. A minimum of mathematics is used. Theory and experiment are described together at every stage. A guide to further reading is provided through carefully selected references. This is a complete and coherent introduction to the subject which no other modern text currently offers.
Rapid development of microfabrication and assembly of nanostructures has opened up many opportunities to miniaturize structures that confine light, producing unusual and extremely interesting optical properties. This book addresses the large variety of optical phenomena taking place in confined solid state structures: microcavities. Realisations include planar and pillar microcavities, whispering gallery modes, and photonic crystals. The microcavities represent a unique laboratory for quantum optics and photonics. They exhibit a number of beautiful effects including lasing, superfluidity, superradiance, entanglement etc. Written by four practitioners strongly involved in experiments and theories of microcavities, it is addressed to any interested reader having a general physical background, but in particular to undergraduate and graduate students at physics faculties.
“If Huckleberry Finn were set on the Mexican-American border and written by the creators of South Park, it might read something like this.” —San Francisco Chronicle Hailed by critics and lauded by readers for its riotously funny and scathing portrayal of America in an age of trial by media, materialism, and violence, Vernon God Little was an international sensation when it was first published in 2003 and awarded the prestigious Man Booker Prize. The memorable portrait of America is seen through the eyes of a wry, young protagonist. Fifteen-year-old Vernon narrates the story with a cynical twang and a four-letter barb for each of his townsfolk, a medley of characters. With a plot involving a school shooting and death-row reality TV shows, Pierre’s effortless prose and dialogue combine to form a novel of postmodern gamesmanship. “A dangerous, smart, ridiculous, and very funny first novel . . . Pierre renders adolescence brilliantly, capturing with seeming effortlessness the bright, contradictory hormone rush of teenage life.” —Sam Sifton, The New York Times
Why does nature prefer some shapes and not others? The variety of sizes, shapes, and irregularities in nature is endless. Skillfully integrating striking full-color illustrations, the authors describe the efforts by scientists and mathematicians since the Renaissance to identify and describe the principles underlying the shape of natural forms. But can one set of laws account for both the symmetry and irregularity as well as the infinite variety of nature's designs? A complete answer to this question is likely never to be discovered. Yet, it is fascinating to see how the search for some simple universal laws down through the ages has increased our understanding of nature. The Parsimonious Universe looks at examples from the world around us at a non-mathematical, non-technical level to show that nature achieves efficiency by being stingy with the energy it expends.
ÒBoys are emotionally illiterate and donÕt want intimate friendships.Ó In this empirically grounded challenge to our stereotypes about boys and men, Niobe Way reveals the intense intimacy among teenage boys especially during early and middle adolescence. Boys not only share their deepest secrets and feelings with their closest male friends, they claim that without them they would go Òwacko.Ó Yet as boys become men, they become distrustful, lose these friendships, and feel isolated and alone. Drawing from hundreds of interviews conducted throughout adolescence with black, Latino, white, and Asian American boys, Deep Secrets reveals the ways in which we have been telling ourselves a false...
