Nico Bloembergen by Rob Herber Pdf

This biography is a personal portrait of one of the best-known Dutch physicists, Nicolaas Bloembergen. Born in 1920 in Dordrecht, Bloembergen studied physics in Utrecht, leaving after World War II for the United States, where he became an American citizen in 1958. At Harvard University, he pioneered nuclear magnetic resonance (NMR, used in chemistry and biology for structure identification; moreover leading to MRI), laser theory and nonlinear optics. In 1978 he was awarded the Lorentz Medal for his contribution to the theory of nonlinear optics (used in fiber optics), and in 1981 he received the Nobel Prize for physics, along with Arthur Schawlow and Kai Siegbahn. The book is based on numerous conversations with Nicolaas Bloembergen himself, his wife Deli Brink, his family, and colleagues in science. It describes his childhood and study in Bilthoven and Utrecht, the first postwar years at Harvard, the discoveries of masers and lasers, and the award of the Nobel Prize. It also delves into Bloembergen's involvement in American politics, particularly his role in Ronald Reagan's controversial "Star Wars" program.

Magnetic Resonance by C. K. Coogan Pdf

TWENTY-FIVE years ago in Russia, Zavoisky made the first experimen tal observation of electron spin resonances; and a year later Purcell, Torrey and Pound at Harvard and Bloch, Hansen and Packard at Stanford ('The Harvard of the West') observed nuclear magnetic resonances for the first time. In both cases (ESR and NMR) the phenomena had been previously predicted, and Gorter - surely one of the most unlucky experimenters of our time - had made his noble attempts to detect magnetic resonances. Purcell et aZ. , having beaten their radar swords into scientific ploughshares, used a re 3 sonant coaxial cavity, filled the inductive part with 850 cm of paraffin, and produced a resonance with a signal-to-noise ratio of 20. They predicted that the sensitivity could be increased several hundred-fold and foresaw applications in determining magnetic mo ments, investigating spin-lattice coupling and measuring magnetic fields. Their letter reached the editor of Phys. Rev. on Christmas Eve 1945, and the basis of NMR in the solid state was laid. Bloch et aZ. , fortunately working independently, established the entirely different, crossed-coil approach to the observation of NMR in a water sample, which they doped with paramagnetic ions to reduce the relaxation times. They had laid the foundation of liquid-state NMR. Their letter to Phys. Rev. was received on 29 January 1946.

Ultra-Low Field Nuclear Magnetic Resonance by Robert Kraus Jr.,Michelle Espy,Per Magnelind,Petr Volegov Pdf

This book is designed to introduce the reader to the field of NMR/MRI at very low magnetic fields, from milli-Tesla to micro-Tesla, the ultra-low field (ULF) regime. The book is focused on applications to imaging the human brain, and hardware methods primarily based upon pre-polarization methods and SQUID-based detection. The goal of the text is to provide insight and tools for the reader to better understand what applications are best served by ULF NMR/MRI approaches. A discussion of the hardware challenges, such as shielding, operation of SQUID sensors in a dynamic field environment, and pulsed magnetic field generation are presented. One goal of the text is to provide the reader a framework of understanding the approaches to estimation and mitigation of low signal-to-noise and long imaging time, which are the main challenges. Special attention is paid to the combination of MEG and ULF MRI, and the benefits and challenges presented by trying to accomplish both with the same hardware. The book discusses the origin of unique relaxation contrast at ULF, and special considerations for image artifacts and how to correct them (i.e. concomitant gradients, ghost artifacts). A general discussion of MRI, with special consideration to the challenges of imaging at ULF and unique opportunities in pulse sequences, is presented. The book also presents an overview of some of the primary applications of ULF NMR/MRI being pursued.

Introduction to Functional Magnetic Resonance Imaging by Richard B. Buxton Pdf

Functional Magnetic Resonance Imaging (fMRI) is now a standard tool for mapping activation patterns in the human brain. This highly interdisciplinary field involves neuroscientists and physicists as well as clinicians who need to understand the rapidly increasing range, flexibility and sophistication of the techniques. In this book, Richard Buxton, a leading authority on fMRI, provides an invaluable introduction for this readership to how fMRI works, from basic principles and the underlying physics and physiology, to newer techniques such as arterial spin labeling and diffusion tensor imaging.

Formation And Evolution Of Black Holes In The Galaxy: Selected Papers With Commentary by Hans A Bethe,Gerald E Brown,Chang-hwan Lee Pdf

In published papers H A Bethe and G E Brown worked out the collapse of large stars and supernova explosions. They went on to evolve binaries of compact stars, finding that in the standard scenario the first formed neutron star always went into a black hole in common envelope evolution. C-H Lee joined them in the study of black hole binaries and gamma ray bursts. They found the black holes to be the fossils of the gamma ray bursts. From their properties they could reconstruct features of the burst and of the accompanying hypernova explosions.This invaluable book contains 23 papers on astrophysics, chiefly on compact objects, written over 23 years. The papers are accompanied by illuminating commentary. In addition there is an appendix on kaon condensation which the editors believe to be relevant to the equation of state in neutron stars, and to explain why black holes are formed at relatively low masses.

Selected Scientific Papers of Sir Rudolf Peierls by Rudolf Ernst Peierls Pdf

This book is a collection of the major scientific papers of Sir Rudolf Peierls (1907-95), including the Peierls-Frisch Memoranda of 1940 on the feasibility, and the predicted human effects, of an atomic bomb made of uranium-235. His papers range widely in topic. They include much on the fundamentals of solid state physics, the thermal and electric conductivity of materials as a function of temperature T (especially T→0), the interpretation of the de Haas-van Alphen effect observed for a metal in a magnetic field, and the basics of transport theory. Many are on problems in statistical mechanics, including his constructive paper demonstrating the existence of a phase transition for Ising's model for a two-dimensional ferromagnet. In nuclear physics, they include the first calculations (with Bethe) on the photo-disintegration of the deuteron (made in response to a challenge by Chadwick), the Kapur-Peierls theory of resonance phenomena in nuclear reactions, the Bohr-Peierls-Placzek continuum model for complex nuclei (which first explained the narrow resonances observed for low energy neutrons incident on very heavy nuclei), and the Peierls-Thouless variational approach to collective phenomena in nuclei. Several of Peierls's wartime papers, now declassified, are here published for the first time.Brief commentaries on most of the papers in this book were added by Peierls, to indicate subsequent developments and their relationship with other work, or to correct errors found later on. A complete bibliography of his writings is given as an appendix.

The Origin Of The Third Family by O Barnabei,Fabio Roversi Monaco,Luciano Maiani,R A Ricci Pdf

In 1967 a group of physicists from the University of Bologna, led by A Zichichi, published a proposal to search for a heavy lepton using the Frascati (e+e-) collider. The proposal, whose key pages are reproduced in this book on the 30th anniversary of the publication, was the consequence of many years of work started at CERN, where, in addition to the original idea of searching for a heavy lepton carrying its own leptonic number, new technologies were invented to allow the detection of a signal whose identification against the high background of hadronic processes was extremely difficult.More than ten years of work by A Zichichi, together with his students and his collaborators, have paved the way for the discovery of the Third Family of fundamental particles. In this authoritative volume, a group of eminent physicists unequivocally establishes the origin of the Third Family of the basic constituents of matter.
