A fifteen year old boy, gifted in science, perplexed by the opposite sex, with parents who give him everything except affection, goes from a normal, everyday earth-boy existence to encountering a mysterious being, druid priest, monk/historian, the beautiful and matronly Queen Ogaboom, extraterrestrials, a black hole named Fudge, and war-gone Wargons. In the process, he discovers himself, comes to the aid of an embattled extraterrestrial race, and sets right the wrongs he's inflicted on his dimension, thus curing a portion of general, all around, universal angst . . . or does he? Is there more to the story? Will the boy come to the aid of the Queen and her planet Doufear? Will he come to the aid of the universe by stopping the Wargons in their plight to take out thousands of years of built up anger? Will earth survive? Will Doufear? The Milky Way? Beta Bot? where the great Augur resides--alleged spiritual healer of the universe. Lots of questions. Little time. Pick up the book. Before it's too late!
By abandoning classical theory and adopting a liberating, empirical approach to fluid behaviour, this book sheds new light on Global Warming, on Ice Ages, why the wind makes waves bigger, and the origin of the Earth’s magnetic field. At heart, it is concerned with how meaning can be extracted from a sequence of measurements—time series analysis. The methods developed (plus Python code) will appeal to both the graduate student and the data analyst. The “Ultraviolet Catastrophe”, the failure to account for black-body radiation, led to quantum mechanics. Another catastrophe was politely ignored and fluid dynamics remained trapped in the nineteenth century. The book outlines a solution to this dilemma. It will appeal to those interested in the philosophy of science and, more specifically, to those interested in understanding the great unsolved mystery of fluid dynamics: turbulence.
"A masterly assessment of the way the idea of quanta of radiation became part of 20th-century physics. . . . The book not only deals with a topic of importance and interest to all scientists, but is also a polished literary work, described (accurately) by one of its original reviewers as a scientific detective story."—John Gribbin, New Scientist "Every scientist should have this book."—Paul Davies, New Scientist
A brand-new edition of the Carnegie Medal-winning THE CHANGEOVER - written by internationally bestselling author, Margaret Mahy. 'A gorgeous, strange, unforgettable story . . . I more than loved it' Laini Taylor - author of Daughter of Smoke and Bone 'A clammy hand pressed Laura down onto her knees beside Jacko's bed. It was the hand of terror, nothing less.' It was a warning. Laura felt it when she looked in the mirror that morning. There had been others: the day her father left home, the day she met Sorensen - the boy with the strange silver eyes. But nothing had prepared Laura for the horror of today. And now her little brother, Jacko, was fighting for his life after being sucked dry of his youth by the sinister Carmody Braque. Laura knows there is only one way to save Jacko; she must join Sorensen and use his supernatural powers to change over if there is to be any hope for her little brother. An unforgettable, supernatural romance.

In the history of science the opening up of a new observational or experimental window is always followed by an increase in knowledge of the subject concerned. This is also the case with the subject of this book, ultraviolet radiation (hereafter UV). In principle, the ultraviolet range might be just one more of these windows, of no particular importance. However, the energy per UV photon provides the main peculiarity, its magnitude being great enough to produce important ch- ical reactions in the atmospheres of planets and satellites, thereby a?ecting the transmission of this radiation to the ground. The Sun is the main natural source of UV radiation in the Solar System and our planet is the body where its in?uences can be best tested and the only one where its relation with life can be studied. However, the terrestrial atmosphere blocksmostofthephotonsinthiselectromagneticrangeandastronomershavehad to develop various techniques (balloons, planes and rockets) to cross this barrier and access the information. These tools have been used in parallel to investigate the physical properties of the terrestrial atmosphere and the interaction of its constituents with light. This book will addresses most of these topics.
The clock is relentlessly ticking! Our world teeters on a knife-edge between a peaceful and prosperous future for all, and a dark winter of death and destruction that threatens to smother the light of civilization. Within 30 years, in the 2030 decade, six powerful 'drivers' will converge with unprecedented force in a statistical spike that could tear humanity apart and plunge the world into a new Dark Age. Depleted fuel supplies, massive population growth, poverty, global climate change, famine, growing water shortages and international lawlessness are on a crash course with potentially catastrophic consequences. In the face of both doomsaying and denial over the state of our world, Colin Mason cuts through the rhetoric and reams of conflicting data to muster the evidence to illustrate a broad picture of the world as it is, and our possible futures. Ultimately his message is clear; we must act decisively, collectively and immediately to alter the trajectory of humanity away from catastrophe. Offering over 100 priorities for immediate action, The 2030 Spike serves as a guidebook for humanity through the treacherous minefields and wastelands ahead to a bright, peaceful and prosperous future in which all humans have the opportunity to thrive and build a better civilization. This book is powerful and essential reading for all people concerned with the future of humanity and planet earth.
It is the end of an historical epoch, but to an old professor of physics, Victor Jakob, sitting in his unlighted study, eating dubious bread with jam made from turnips, it is the end of a way of thinking in his own subject. Younger men have challenged the classical world picture of physics and are looking forward to observational tests of Einstein's new theory of relativity as well as the creation of a quantum mechanics of the atom. It is a time of both apprehension and hope. In this remarkable book, the reader literally inhabits the mind of a scientist while Professor Jakob meditates on the discoveries of the past fifty years and reviews his own life and career--his scientific ambitions and his record of small successes. He recalls the great men who taught or inspired him: Helmholtz, Hertz, Maxwell, Planck, and above all Paul Drude, whose life and mind exemplified the classical virtues of proportion, harmony, and grace that Jakob reveres. In Drude's shocking and unexpected suicide, we see reflected Jakob's own bewilderment and loss of bearings as his once secure world comes to an end in the horrors of the war and in the cultural fragmentation wrought by twentieth-century modernism. His attempt to come to terms with himself, with his life in science, and with his spiritual legacy will affect deeply everyone who cares about the fragile structures of civilization that must fall before the onrush of progress.
It is shown that in the non-relativistic case, the ultraviolet divergence in the integrals for the electromagnetic shift of energy of the bound states of hydrogen is due to the neglect of the retardation in computing the matrix elements of the electromagnetic interaction p.A. When the exact matrix elements are used, there is no ultraviolet divergence. For the case of the shift of the ground state, the contributions to the shift from the two closest levels are computed and shown to be very small. (Author).
