It is through images that we understand the form and function of material objects, from the fundamental particles that are the constituents of matter to galaxies that are the constituents of the Universe. Imaging must be thought of in a flexible way as varying from just the detection of objects -- a blip on a screen representing an aircraft or a vapour trail representing the passage of an exotic particle -- to displaying the fine detail in the eye of an insect or the arrangement of atoms within or on the surface of a solid. The range of imaging tools, both in the type of wave phenomena used and in the devices that utilize them, is vast. This book will illustrate this range, with wave phenomena covering the entire electromagnetic spectrum and ultrasound, and devices that vary from those that just detect the presence of objects to those that image objects in exquisite detail. The word fundamentals' in the title has meaning for this book. There will be no attempt to delve into the fine technical details of the construction of specific devices but rather the book aims to give an understanding of the principles behind the imaging process and a general account of how those principles are utilized.
'Each chapter ends with up to six student problems. There is full set of worked answers at the end of the book but modern students might not be enlightened by the samples of Fortran code, probably meant to illustrate how realistic calculations might be made.'Contemporary PhysicsOn a clear and moonless night, especially in remote areas such as deserts, myriads of points of light cover the sky. The great majority of them are stars, many like the Sun, but so far away that they can only be seen as point sources of light. The problem faced by astronomers is to find their properties and distances, just from the light they emit. This is done by using the knowledge of science, mainly physics, acquired from small-scale experiments carried out on Earth. However, the stars themselves are laboratories in which matter behaves in ways that cannot be reproduced on Earth so, in finding out about stars, we complement scientific knowledge gained from earthbound experimentation.This book describes the means - some very ingenious - by which to explore the properties, locations and planetary companions of stars, and provides a sound foundation for further study.
Two models for the origin of the Solar System, the Nebula Theory and the Capture Theory, are discussed by protagonists, Simon and Steven respectively, in the presence of Solomon, who oversees the discussions. Modelled on Galileo's Dialogue Concerning the Two Chief World Systems, this book provides new insight into different theories of cosmogony.The Nebula Theory, at present the standard model of planet formation, proposes that a star and planets are derived from a single spinning nebula. Woolfson here introduces an alternative, the Capture Theory, in which planets are produced from a protostar tidally disrupted by a condensed star which 'captures' most of the formed planets into orbits. These complex ideas are simplified and presented in an easily understandable, accessible way for all students of physics, astronomy, cosmology and those interested in the beginning of our world as we know it.
Colour makes our lives more interesting - how dull it would be in a black-and-white world! It pleases us aesthetically, entertains us and is useful to us. This unique book aims to describe the scientific nature of colour and light, and how we see it, in an accessible and easily understandable style. The evolution of the eye, science of colour and technical visual systems are all broken down into readable chapters, with clear images and illustrations provided for reference. The book then goes on to discuss the innate tendency of humankind to produce artistic works as conceived, realised and augmented through the use of colour. Focussing on broad forms of artistic entertainment - painting with pigments and dyes, colour and light in photography and cinematography, light displays and colour in television - this book then delivers a comprehensive review of what colour means and has meant in the creative arts.
Time and Age explores how time is defined by man. It follows the development of our means for measuring time from early methods using the flow of water or the steady burning of candles through to the atomic clock that records time with incredible precision.The classical idea of time as something that progresses at a uniform rate and as something that is the same to all observers was overturned by Einstein's Theory of Relativity. The conclusions coming from this theory are described, including the anti-intuitive twin paradox where one twin, returning from a journey to a distant star, is younger than his twin brother.Also covered is how age can be determined in a wide range of situations, such as how we work out the age of the Universe to how we calculate the age of artefacts that are just a few centuries old.

This book explores a large number of resonance effects that occur both in everyday life and in scientific contexts. It is a topic that provides a cross-link between many branches of science and shows how a single scientific principle can manifest itself in many, apparently disparate, ways.Resonance covers fields as diverse as civil engineering in relation to the safety of bridges, the quality of sound from musical instruments, the behaviour of electrical circuits, lasers, the orbits of solar-system bodies, the scattering of X-rays from atoms and the exploration of the structures of molecules, atoms and nuclei.The essential mathematics included should be accessible to any science undergraduate, no matter the discipline of their study. Problems and solutions are provided for every chapter to help reinforce understanding of the material.

This fully-updated second edition remains the only truly detailed exploration of the origins of our Solar System, written by an authority in the field. Unlike other authors, Michael Woolfson focuses on the formation of the solar system, engaging the reader in an intelligent yet accessible discussion of the development of ideas about how the Solar System formed from ancient times to the present.Within the last five decades new observations and new theoretical advances have transformed the way scientists think about the problem of finding a plausible theory. Spacecraft and landers have explored the planets of the Solar System, observations have been made of Solar-System bodies outside the region of the planets and planets have been detected and observed around many solar-type stars. This new edition brings in the most recent discoveries, including the establishment of dwarf planets and challenges to the 'standard model' of planet formation - the Solar Nebula Theory.While presenting the most up-to-date material and the underlying science of the theories described, the book avoids technical jargon and terminology. It thus remains a digestible read for the non-expert interested reader, whilst being detailed and comprehensive enough to be used as an undergraduate physics and astronomy textbook, where the formation of the solar system is a key part of the course.Michael Woolfson is Emeritus Professor of Theoretical Physics at University of York and is an award-winning crystallographer and astronomer.

The three greatest scientific mysteries, which remain poorly understood, are the origin of the universe, the origin of life and the development of consciousness. This book describes the processes preceding the Big Bang, the creation of matter, the concentration of that matter into stars and planets, the development of simple life forms and the theory of evolution that has given higher life forms, including mankind.There are many popular and excellent science books that present various aspects of science. However, this book follows a narrow scientific pathway from the Big Bang to mankind, and depicts the causal relationship between each step and the next. The science covered will be enough to satisfy most readers. Many important areas of science are dealt with, and these include cosmology, particle physics, atomic physics, galaxy and star formation, planet formation and aspects of evolution. The necessary science is described in a narrative form that general-interest readers should understand, without the use of equations or formulae.This 2nd edition includes several updates on the subjects that form the pillars of this book. They are: cosmology and astronomy, the features and formation of the solar system, the origin of life, and genetics and evolution. This book will appeal to readers with an interest in biology and those curious about the origins of the universe.

Probability and statistics impinge on the life of the average person in a variety of ways - as is suggested by the title of this book. Very often information is provided that is factually accurate but intended to give a biased view. This book presents the important results of probability and statistics without making heavy mathematical demands on the reader. It should enable an intelligent reader to properly assess statistical information and to understand that the same information can be presented in different ways.In this second edition the author presents a new chapter exploring science and society including the way that scientists communicate with the public on current topics, such as global warming. The book also investigates pensions and pension policy, and how they are influenced by changing actuarial tables.

The book begins with a historical review of four major theories for the origin of the Solar System in particular, or of planets in general, which highlight the major problems that need to be solved by any plausible theory. In many theories, including that which form the major theme of this book, the formation of planets and stars is intimately linked, so four chapters are devoted to the processes that can be described as the birth, life and death of stars.Recent observations that have revealed the existence of planets around many Sun-like stars are described in detail, followed by a clear exposition of the Capture Theory for the origin of planets. Many aspects of this theory are illustrated with sophisticated computer modelling that convincingly demonstrates the plausibility of the theory. The Capture Theory is in complete accord with all observations, including the estimate it gives for the proportion of Sun-like stars with planets. It is the only theory that sits comfortably with all present observational and theoretical constraints.The general theory of planet formation does not explain the detailed structure of the Solar System. An early postulated collision of two major planets is shown to explain many disparate features of the Solar System - the nature of the terrestrial planets, surface features of the Moon and its relationship with Earth, asteroids, comets and dwarf planets, the relationship between Neptune, Triton and Pluto and the characteristics of meteorites, including the isotopic anomalies found in them. The postulate of a planetary collision is given support by a 2009 NASA observation of the residue of such an event around a distant young star.

This book traces the history of ideas about the nature of matter and also the way that mankind has used material resources that the world offers. Starting with the ideas of ancient civilizations that air, earth, fire and water were the basic ingredients of all matter, it traces the development of the science of chemistry beginning within the ranks of the alchemists. First, the idea of elements grew and then the atomic nature of matter was verified. Physicists had entered the scene, showing the nature of atoms in terms of fundamental particles and then introducing the concept of wave-particle duality that altered the basic concepts of what matter was. Finally the physicists discovered a panoply of fundamental particles, some observed within atom-smashing machines and the existence of others merely postulated. In parallel with the above there is a description of various kinds of matter as it affects everyday life including the nature of matter associated with life itself. The way that early man used the materials directly given by nature, such as stone, wood and animal skins, is followed by the use of materials requiring some process to be employed, e.g. metals which include bronze and also concrete. Some important modern materials are discussed, such as synthetic fibres and plastics and semiconductors, and potentially important future products from new developments in nanotechnology.

Consider the status of music education as you read Music Education at a Crossroads, a collection of addresses from the Centennial Congress of MENC: The National Association for Music Education. Noted leaders in music education including Paul Lehman, Bennett Reimer, Samuel Hope, and Michael Mark joined Brenda Welburn and Anne Bryant in addressing the challenges and opportunities faced by music educators today. The Centennial Congress renewed a shared professional commitment to a comprehensive music education for all students and discussed the impediments to the vision of the Centennial Declaration: "It is the right of every child to receive a balanced, comprehensive, sequential music education taught by qualified music teachers."
Most well-read, but non-scientific, people will have heard of the term "Big Bang" as a description of the origin of the Universe. They will recognize that DNA identifies individuals and will know that the origin of life is one of the great unsolved scientific mysteries. This book brings together all of that material. Starting with the creation of space and time - known as the Big Bang - the book traces causally related steps through the formation of matter, of stars and planets, the Earth itself, the evolution of the Earth's surface and atmosphere, and then through to the beginnings of life and the evolution of man. The material is presented in such a way that a non-scientist can comprehend it, without using formulae or equations but still preserving the integrity of the involved science. This book does not solve the mysteries of what initiated the Big Bang or how life evolved from inanimate matter, but it does make clear the nature of those problems. The reader will be left with a sense of wonderment that he or she actually exists! |
