  • The application of radiation in human health, for both diagnosis and treatment of disease, is an important component of the work of the IAEA. The responsibility for the increasingly technical aspects of this work is undertaken by the medical physicist. To ensure good practice in this vital area, structured clinical training programmes are required to complement academic learning. This publication is intended to be a guide to the practical implementation of such a programme for nuclear medicine.

  • This book is written for those physicists who want to work on Wall Street but have not bothered to read anything about Finance. This is a crash course that the author, a physicist himself, needed when he landed a financial data analyst job and became fascinated with the huge data sets at his disposal. More broadly, this book addresses the reader with some background in science or engineering (college-level math helps) who is willing to learn the basic concepts and quantitative methods used in modern finance.

  • If science has the equivalent of a Bloomsbury group, it is the five men born at the turn of the twentieth century in Budapest: Theodore von Karman, Leo Szilard, Eugene Wigner, John von Neumann, and Edward Teller. From Hungary to Germany to the United States, they remained friends and continued to work together and influence each other throughout their lives. As a result, their work was integral to some of the most important scientific and political developments of the twentieth century.

  • Ato Z of Physicists is an up-to-date biographical dictionary containing profiles of 150 of the most illustrious figures in the history of physics. It provides a comprehensive and accessible guide to the men and women behind the ideas that have shaped the modern vision of physical reality. These biographical essays, focusing on individual struggles and achievements, never lose sight of the communal nature of physics: the ways in which the lives and works of physicists are interconnected....

  • Physicists pretend not only to know everything, but also to know everything bet- ter. This applies in particular to computational statistical physicists like US. Thus many of our colleagues have applied their computer simulation techniques to fields outside of physics, and have published sometimes in biological, economic or sociological journals, and publication flow in the opposite direction has also started.

  • This document is historic for two major reasons. First, it represents the first jointly authorized publication by both American Association of Medical Physicists (AAPM) and American College of Medical Physics (ACMP). This document began as a 1991 ACMP report. In 1997 the General Medical Physics committee of AAPM invited Dr. Brahmavar, who authored the original report, to chair a task group to rewrite and update the document as an AAPM task group report. As it neared completion, there was a suggestion that perhaps ACMP would be interested in supporting the revised document.

  • This book is an introduction to computer science. Computer science is the study of computer hardware, algorithms, and data structures and how they fit together to provide information systems. Each of these topics can be studied at various levels. For example, physicists study the properties of matter that allow hardware components to be designed, electrical engineers study how the components can be combined to produce circuits, and computer engineers study how circuits can be combined to produce computers.

  • Michael Faraday, an English experimental physicist, was the son of a poor blacksmith. After very little schooling he was apprenticed to a bookbinder. The boy worked hard all day and studied at night. One day a man on entering the shop found a boy at work binding an encyclopedia, and at the same time studying hard at the article on electric in it. The man was surprised to see the boy so interested in a very difficult subject and questioned him.

  • In banking, especially in risk management, portfolio management, and structured finance, solid quantitative know-how becomes more and more important. We had a two-fold intention when writing this book: First, this book is designed to help mathematicians and physicists leaving the academic world and starting a profession as risk or portfolio managers to get quick access to the world of credit risk management. Second, our book is aimed at being helpful to risk managers looking for a more quantitative approach to credit risk. ...

  • Scientists often have the feeling that, through their work, they are learning about some aspect of themselves. Physicists see this connection in their work; so do, for example, psychologists and chemists. In the study of robotics, the connection between the field of study and ourselves is unusually obvious. And, unlike a science that seeks only to analyze, robotics as currently pursued takes the engineering bent toward synthesis. Perhaps it is for these reasons that the field fascinates so many of us.

  • Physicist Robert Lang has taken the ancient art of origami to new dimensions. "Part of the challenge of folding is to capture the feeling I get when I look at real animals," says Robert Lang. Animals Out of Paper is set somewhere near Boston right now. From cows and birds to panda bears and other animals, a group of about 20 local Kindergarteners have spent the summer creating origami that will now be available for free at the Harrison Library.

  • There is no gravitational pull . . . only a push! This hypothesis provides a general model for the mechanics of gravitation. It in no way refutes the observed behavior of gravitation, but merely seeks to explain it. I have based all but a single aspect of this model on established scientific knowledge, and that single aspect is my prediction of an unknown. (So it remains to be proved or disproved.) The team of medieval physicists stepped out of the time machine and began to examine the strange, new device fastened to the window. They had never before seen a...

  • Physics is the study of matter and energy in space and time and how they are related to each other. Physicists assume (take as given) the existence of mass, length, time and electric current and then define (give the meaning of) all other physical quantities in terms of these basic units. Mass, length, time, and electric current are never defined but the standard units used to measure them are always defined.

  • As science has become more interdisciplinary and impinges ever more heavily on technology, we have been led to the conclusion that there is a great need now for a textbook that emphasizes the physical and chemical origins of the properties of solids while at the same time focusing on the technologically important materials that are being developed and used by scientists and engineers.

  • IT HAS BEEN SAID THAT SIR ISAAC NEWTON was the last person to know everything. He was an accomplished physicist (his three laws of motion were the basis of classical mechanics, which defi ned astrophysics for three centuries), mathematician (he was one of the inventors of calculus and developed Newton’s Method for fi nding roots of equations), astronomer, natural philosopher, and alchemist (okay, maybe the last one was a mistake). He invented the refl ecting telescope, a theory of color, and a law of cooling, and he studied the speed of sound.
