Book Description
Proton Therapy Physics goes beyond current books on proton therapy to provide an in-depth overview of the physics aspects of this radiation therapy modality, eliminating the need to dig through information scattered in the medical physics literature. After tracing the history of proton therapy, the book summarizes the atomic and nuclear physics background necessary for understanding proton interactions with tissue. It describes the physics of proton accelerators, the parameters of clinical proton beams, and the mechanisms to generate a conformal dose distribution in a patient. The text then covers detector systems and measuring techniques for reference dosimetry, outlines basic quality assurance and commissioning guidelines, and gives examples of Monte Carlo simulations in proton therapy. The book moves on to discussions of treatment planning for single- and multiple-field uniform doses, dose calculation concepts and algorithms, and precision and uncertainties for nonmoving and moving targets. It also examines computerized treatment plan optimization, methods for in vivo dose or beam range verification, the safety of patients and operating personnel, and the biological implications of using protons from a physics perspective. The final chapter illustrates the use of risk models for common tissue complications in treatment optimization. Along with exploring quality assurance issues and biological considerations, this practical guide collects the latest clinical studies on the use of protons in treatment planning and radiation monitoring. Suitable for both newcomers in medical physics and more seasoned specialists in radiation oncology, the book helps readers understand the uncertainties and limitations of precisely shaped dose distribution.

Book Description
Most elements are synthesized, or "cooked", by thermonuclear reactions in stars. The newly formed elements are released into the interstellar medium during a star's lifetime, and are subsequently incorporated into a new generation of stars, into the planets that form around the stars, and into the life forms that originate on the planets. Moreover, the energy we depend on for life originates from nuclear reactions that occur at the center of the Sun. Synthesis of the elements and nuclear energy production in stars are the topics of nuclear astrophysics, which is the subject of this book. It presents nuclear structure and reactions, thermonuclear reaction rates, experimental nuclear methods, and nucleosynthesis in detail. These topics are discussed in a coherent way, enabling the reader to grasp their interconnections intuitively. The book serves both as a textbook for advanced undergraduate and graduate students, with worked examples and end-of-chapter excercises, but also as a reference book for use by researchers working in the field of nuclear astrophysics.

Book Description
Dramatic progress has been made in all branches of physics since the National Research Council's 1986 decadal survey of the field. The Physics in a New Era series explores these advances and looks ahead to future goals. The series includes assessments of the major subfields and reports on several smaller subfields, and preparation has begun on an overview volume on the unity of physics, its relationships to other fields, and its contributions to national needs. Nuclear Physics is the latest volume of the series. The book describes current activity in understanding nuclear structure and symmetries, the behavior of matter at extreme densities, the role of nuclear physics in astrophysics and cosmology, and the instrumentation and facilities used by the field. It makes recommendations on the resources needed for experimental and theoretical advances in the coming decade.

Book Description
In November 1891, wealthy former abolitionist and Chicago politician Amos Throop founded a thoroughly undistinguished small college in Pasadena, California, which he named after himself. Millikan’s School is the history of this institution that stands today at the pinnacle of world academics, with 300 full-time faculty, nearly 1,000 undergraduate, 1,250 graduate students and 39 Caltech and alumni Nobel Prize recipients. Although Amos Throop — the name of the college was changed to Caltech in 1920 — could not have realized the importance of geography, the fact that Pasadena lay at the foot of Mount Wilson, was central to its success: astronomer George Ellery Hale built his telescope there in 1902, the finest at that time in the world. Later Hale joined the board of trustees of the struggling school and persuaded Arthur Amos Noyes, former president of MIT and the nation’s leading physical chemist, to join him in Pasadena. The third member of Caltech’s founding troika was renowned physicist Robert A. Millikan from the University of Chicago. The dedication of Caltech in 1920 and the proclamation of what it stood for in science and education set the stage for Millikan, who functioned as the school’s president, to bring the best and the brightest from all over the world — Theodore von Kármán in aeronautics, Thomas Hunt Morgan in biology, Paul Sophus Epstein in physics, Beno Gutenberg in seismology, Linus Pauling in chemistry — to Pasadena to work in an ever larger number of areas in science and technology. The book also covers the funding, planning and construction of the 200-inch telescope on Palomar Mountain, Willy Fowler’s work in nuclear astrophysics and the wartime rocket experiments that grew into the Jet Propulsion Laboratory (JPL), today the world leader in deep-space exploration. “Millikan’s School presents an interesting and thoroughly reliable account of the astonishing change over a period of a few years of a small technical school in Pasadena, California, into one of the world’s leading scientific institutions. “ — Linus Pauling “In Millikan’s School, Judith Goodstein tells the remarkable story of the rise of Caltech... She details how Millikan, aided by Hale and Arthur Amos Noyes, America’s leading physical chemist and another of Hale’s inspired acquisitions, took a former trade school and forged from it a ‘grandiose university among the orange groves’... It would be impossible, while reading Goodstein’s lively account, not to be impressed by the energy, drive and boundless enthusiasm of men like Millikan, Hale and Noyes... [who] had the bare-faced audacity to set about building an institute to rival the cream of the universities of Europe and America.” — Marcus Chown, New Scientist “[Goodstein’s] story is first and foremost the tale of three men: the astronomer George Ellery Hale, the chemist Alfred Noyes, and the physicist Robert Millikan. It is the story of their attempts to transform an undistinguished little school founded in 1891... into a world-class scientific establishment... [A] useful book.” — Tony Rothman, Science “In Millikan’s School, the story of Throop [University]’s transformation into Caltech is told with precision... Judith Goodstein’s history offers a quick tour of the landmarks of science in the mid-20th Century and a glance at how pure science puts itself at the service of government, commerce and the military... Goodstein... approaches her subject with a healthy sense of humor and an acute sense of academic politics. She tells a wonderful story about how Caltech lost to Princeton in a bidding war over the services of Albert Einstein, for example... To her credit, Goodstein asks the hard question: ‘What is the best way to do science?’... Millikan’s School offers enough hard data to enable us to come to our own conclusions.” — Jonathan Kirsch, Los Angeles Times “A cleanly written, scientifically well informed account of one of the world’s foremost institutions for science and technology.” — Ed Regis, Nature “Relying on archival material, published secondary sources, and interviews with institute scientists, Goodstein presents a highly readable account of Caltech’s beginnings at the turn of the century... substantive, informative, and a good read.” — Rebecca S. Lowen, Technology and Culture “As a history of science, this book is well crafted. Orderly in its flow, it is not only a tribute to Millikan, but also places him within the development of physics as a field.” — Andrew Rolle, Southern California Quarterly “A fascinating history that speaks to issues far larger than Cal Tech itself... This well-written and honest account (witness the many cited instances of anti-Semitism in the scientific world) is both a good read and a sobering reminder that big science and top schools are not brought by storks.” — Carroll Pursell, History of Education Quarterly “The author focuses on the personalities and the research fields of the principal scientific figures... The [...] emphasis on personalities, and capsule surveys of relevant scientific fields produce a book that can be apprehended by a wide audience.” — Roger Geiger, Isis “This chronicle offers glimpses of the passion and drive that have motivated a roster of distinguished scientists.” — Publishers Weekly “A lively tale... [Goodstein’s] individual profiles are lean and candid; her background on subjects as diverse as nuclear astrophysics, seismology, aeronautical design, quantum mechanics and rocket fuel are crisp and understandable... With a light style... and meticulous documentation, Goodstein has produced a tale worthy of her subject... “ — Marshall Robinson, Foundation News “A distinguished and uniquely American institution has found its chronicler and its chronicle in Judith Goodstein’s thorough but compact story of Millikan ‘s School. The emergence of Caltech as a powerhouse of science and engineering and a makeweight in the technological advancement of 20th century industry is both beautifully and reliably presented.” — Harry Woolf, Institute for Advanced Study, Princeton University
