Book Description
The 1991 NRC decadal survey for astronomy and astrophysics included a project called the Millimeter Array (MMA). This instrument would be an array of millimeter-wavelength telescopes intended to capture images of star-forming regions and distant star-burst galaxies. With the addition of contributions form Europe, the MMA evolved into the Atacama Large Millimeter Array (ALMA), a proposed array of 64, 12-meter antennas. The project is now part of the NSF Major Research Equipment and Facilities budget request. Increased costs, however, have forced the NSF to reconsider the number of antennas. To help with that review, NSF asked the NRC to assess the scientific consequences of reducing the number of active antennas from 60 to either 50 or 40. This report presents an assessment of the effect of downsizing on technical performance specifications, performance degradation, and the ability to perform transformational science, and of the minimum number of antennas needed.

Book Description
This open access book on the history of the National Radio Astronomy Observatory covers the scientific discoveries and technical innovations of late 20th century radio astronomy with particular attention to the people and institutions involved. The authors have made extensive use of the NRAO Archives, which contain an unparalleled collection of documents pertaining to the history of radio astronomy, including the institutional records of NRAO as well as the personal papers of many of the pioneers of U.S. radio astronomy. Technical details and extensive citations to original sources are given in notes for the more technical readers, but are not required for an understanding of the body of the book. This book is intended for an audience ranging from interested lay readers to professional researchers studying the scientific, technical, political, and cultural development of a new science, and how it changed the course of 20th century astronomy.

Book Description
In 1995, the National Science Foundation (NSF) created a special account to fund large (several tens of millions of dollars) research facilities. Over the years, these facilities have come to represent an increasingly prominent part of the nation's R&D portfolio. Recently concern has intensified about the way NSF is selecting projects for this account. In 2003, six U.S. Senators including the chair and ranking member of the Senate Subcommittee on VA, HUD, and Independent Agencies Appropriations expressed these concerns in a letter to the NRC asking it to "review the current prioritization process and report to us on how it can be improved." This report presents a series of recommendations on how NSF can improve its priority setting process for large research facilities. While noting that NSF has improved this process, the report states that further strengthening is needed if NSF is to meet future demands for such projects.

Book Description
This book summarizes the science to be carried out by the upcoming Cherenkov Telescope Array, a major ground-based gamma-ray observatory that will be constructed over the next six to eight years. The major scientific themes, as well as core program of key science projects, have been developed by the CTA Consortium, a collaboration of scientists from many institutions worldwide.CTA will be the major facility in high-energy and very high-energy photon astronomy over the next decade and beyond. CTA will have capabilities well beyond past and present observatories. Thus, CTA's science program is expected to be rich and broad and will complement other major multiwavelength and multimessenger facilities. This book is intended to be the primary resource for the science case for CTA and it thus will be of great interest to the broader physics and astronomy communities. The electronic version (e-book) is available in open access.

Book Description
This substantially rewritten and expanded fourth edition outlines the most up-to-date methods and tools of radio astronomy. Tools of Radio Astronomy gives a unified treatment of the entire field of radio astronomy, from centimeter to sub-millimeter wavelengths and using single telescopes as well as interferometers. The basic physical principles are described and a complete outline of the instrumentation, observational techniques, and methods of measurement and analysis are given. The goal of this standard reference and text is to prepare readers to carry out observations and relate the data to physical processes in interstellar space. In this fourth edition, the chapter on interferometry and aperture synthesis has been thoroughly revised in the light of most recent developments, as has been the chapter on molecules in interstellar space, and material on receiver technology. From reviews of previous editions: "People use this book so much because it describes what one needs in order actually to do radio astronomy ... and it will remain relevant for a long time...This book is an excellent graduate level text - the best available by far. It is also the best reference book for the practising astronomer who wants to do radio astronomy properly, to interpret the jargon or to understand some of the details of current literature." Physics Today "This is the one book you should buy if you want to become a radio astronomer. (...) I have used the first and second editions as a postgraduate textbook for many years, and will now recommend the third edition to my students." The Observatory.

Book Description
The Book Block is a manual of industrial binding techniques, the first in the Making a Book collection, which focuses on manuals for graphic book production. With the aim of elevating knowledge about graphic production among designers — helping them to produce better books and communicate more effectively with all those involved in the process — The Book Block brings together the 17 most common industrial binding techniques in 6 categories, exploring each one in detail, describing them and showing what is possible to do in this day and age. Conceived from scratch to be bilingual, in Portuguese and English, the book seeks to systematize Portuguese terminology in the printing industry, while providing the same information in the lingua franca of today’s global market: English. In an international context, with customers, employees and producers sprinkled throughout the world, this book provides the perfect tool for an effective communication. Developed by experienced book designers and bookbinders — Itemzero and Maiadouro — this book is a summary of decades of know-how, now easily made available.

Book Description
Annotation Papers from a May 2000 conference explore the role of gas in galaxy evolution, starting with the early universe, continuing through recombination, galaxy formation, and re-ionization, and ending with the local universe. Emphasis is on the interplay between galaxies and their environment, with examination of questions surrounding residual gas signatures of the formation process around galaxies, the possibility of galaxy evolution along the Hubble sequence, and lessons to be learned about the history and fate of galaxies from the structures of their gaseous envelopes. The book includes some 200 H1 and optical images of optically weird galaxies, and of optically normal galaxies with weird H1. Annotation c. Book News, Inc., Portland, OR (booknews.com)
