Early Synchrotrons in Britain, and Early Work for Cern
EARLY SYNCHROTRONS IN BRITAIN, AND EARLY WORK FOR CERN J. D. Lawson Formerly Rutherford Appleton Laboratory, Chilton, Oxon, UK Abstract Early work on electron synchrotrons in the UK, including an account of the conversion of a small betatron in 1946 to become the world’s first synchrotron, is described first. This is followed by a description of the design and construction of the 1 GeV synchrotron at the University of Birmingham which was started in the same year. Finally an account is given of the work of the international team during 1952–3, which formed the basis for the design of the CERN PS before the move to Geneva. It was during this year that John Adams showed the outstanding ability that later brought the project to such a successful conclusion. 1 EARLY PLANS IN BRITAIN: THE WORLD’S FIRST SYNCHROTRON During the second world war Britain’s nuclear physicists were deployed in research directed towards winning the war. Many were engaged in developments associated with radar, (or ‘radiolocation’ as it was then called), both at universities and at government laboratories, such as the radar establishments TRE and ADRDE at Malvern. Others contributed to the atomic bomb programme, both in the UK, and in the USA. Towards the end of the war, when victory seemed assured, the nuclear physicists began looking towards the peacetime future. The construction of new particle accelerators to achieve ever higher energies was seen as one of the more important possibilities. Those working at Berkeley on the electromagnetic separator were familiar with the accelerators there, and following the independent invention (or discovery?) there of the principle of phase stability by Edwin McMillan in 1945, exciting possibilities were immediately apparent [4]. -

BIOTECH PIONEER AND CO-FOUNDER OF CETUS Interviews Conducted by Sally Smith Hughes in 2003 Copyright © 2006 by The Regents of the University of California Since 1954 the Regional Oral History Office has been interviewing leading participants in or well-placed witnesses to major events in the development of northern California, the West, and the nation. Oral history is a method of collecting historical information through tape-recorded interviews between a narrator with firsthand knowledge of historically significant events and a well-informed interviewer, with the goal of preserving substantive additions to the historical record. The tape recording is transcribed, lightly edited for continuity and clarity, and reviewed by the interviewee. The corrected manuscript is indexed, bound with photographs and illustrative materials, and placed in The Bancroft Library at the University of California, Berkeley, and in other research collections for scholarly use. Because it is primary material, oral history is not intended to present the final, verified, or complete narrative of events. It is a spoken account, offered by the interviewee in response to questioning, and as such it is reflective, partisan, deeply involved, and irreplaceable. ************************************ All uses of this manuscript are covered by legal agreements between The Regents of the University of California and Ronald Cape, dated December 18, 2003.

Figuring out a Date Archaeologists Cannot Always Immediately Give a Date for Some Things They Find
Figuring Out a Date Archaeologists cannot always immediately give a date for some things they find. One way archaeologists try to figure out dates is by comparing kinds of materials used to make things. Early people used stone tools. Eventually, people discovered metal, which was better than stone, and they began using that. Archaeologists know that stone was used before metal because they find stone in deeper layers in the stratigraphy. How the ax developed: 1. The first axes were held in the hand. 2. Polished stone axes were used by the earliest farmers to clear land. 3. The first bronze axes copied the stone ones 4. Bronze axes developed to fit in wooden handles. 5. A new development used a loop to hold the ax to the handle. 6. A strong modern ax has a steel head. In the 1940s, there was a revolution in archaeology. An American chemist named Willard Libby discovered a new method for dating objects from the distant past, called radiocarbon, or carbon-14 dating. It is based on the scientific principle that all living things contain a certain amount of radioactive carbon. Once a living thing dies, carbon begins to decay. Scientists know that half of the carbon decays in 5,730 years. Measuring how much radioactive carbon is present in a sample gives a date. This kind of dating can be used for rocks, pottery, and glass. Charcoal is always a good sample for radiocarbon dating.

University, Rajasthan-333001, India. *[email protected] Abstract: The Research Paper consists mainly of the birth dates of scientists and philosophers Before Christ (BC) and After Death (AD) starting from Thales of Miletus with a brief description of their work and contribution to the development of Physics. The author has taken up some 400 odd scientists and put them in a chronological order. Nobel laureates are considered separately in the same paper. Along with the names of researchers are included few of the scientific events of importance. The entire chain forms a cascade and a ready reference for the reader. The graph at the end shows the recession in the earlier centuries and its transition to renaissance after the 12th century to the present. Keywords: As the contents of the paper mainly consists of names of scientists, the key words are many and hence the same is not given I. INTRODUCTION As the material for the topic is not readily available, it is taken from various sources and the collection and compiling is a Herculean task running into some 20 pages. It is given in 3 parts, Part I, Part II and Part III. In Part I the years are given in Chronological order as per the year of birth of the scientist and accordingly the serial number. -

26 27 he San Francisco Bay Area is a major metropoli- tan area of approximately six million people and Tone of the most scenic regions in the United States. The Bay Area includes the major cities of San Francisco and Oakland, as well as Berkeley, home of the world- renowned University of California. Just south is the city of San Jose and the Silicon Valley, home to many of the world’s high-tech companies. The Bay Area also lies within easy driving distance of the high Sierra resorts of Lake Tahoe and Yosemite, the Monterey/Carmel penin- sula, the world famous Napa wine country, and the spec- tacular Mendocino Coast. Everyone knows “The City” - San Francisco - from count- less photographs, movies and television shows that cap- ture its magic. It is a city built on a series of more than 40 hills, offering panoramic views of every kind. The hub of a nine-county complex and the financial and insurance capi- tal of the world, San Francisco has a resident population of about 740,000. San Francisco is situated on a 46.6 square-mile peninsula bounded on the west by the Pa- cific Ocean, on the north by the Golden Gate strait, and from north to east by the San Francisco Bay. The City has been named the world’s top city twice by readers of Conde Nast Traveller and the top U.S. city seven times since 1988. The San Francisco Bay is spanned by two landmarks, the Golden Gate and San Francisco-Oakland Bay bridges, and graced by four islands: Alcatraz, Angel, Yerba Buena and Treasure. -

The Glacial World According to Wally
THE GLACIAL WORLD ACCORDING TO WALLY W.S. BROECKER ELDIGO PRESS 2002 THE GLACIAL WORLD ACCORDING TO WALLY W.S. BROECKER LAMONT-DOHERTY EARTH OBSERVATORY OF COLUMBIA UNIVERSITY Palisades, NY 10964 September 1992 Second Revised Edition June 1995 Third Revised Edition August 2002 FOREWORD In 1990 I started a book on glacial climates. I planned four sections, one on indicators, one on clocks, one on records and finally, one on the physics of the system. After completing the first three of these, I got stuck in my attempt to come up with a conceptual view of what might be driving these changes. However, having taught a course on climate change for many years, I know that much of the information one needs is not available in textbook form. Instead, we all depend heavily on reprints. As this proves to be an inefficient route for students interested in learning the basics of our field, I have tried to capture many of these basics in the first three sections of my would-be book. As I realized that it would be several years before I completed this project, I thought it might be useful to the community if I were to make available the three largely completed sections. This was done in 1992. In preparation for use in a short course to be taught at the Geological Society of America in November 2002, I undertook an effort to update the first three sections and the references during the early part of 2002. I encourage purchasers of the book to make as many copies as they wish for use by students and colleagues. -
Nobel Laureate Glenn T. Seaborg Honored with Endowed Chair; Chemistry Professor Alexander Pines Named Chairholder
04.20.98 - Nobel Laureate Glenn T. Seaborg honored with end... http://www.berkeley.edu/news/media/releases/98legacy/04_20_... NEWS RELEASE, 04/20/98 Nobel Laureate Glenn T. Seaborg honored with endowed chair; chemistry Professor Alexander Pines named chairholder By Jane Scheiber BERKELEY -- Nobel Laureate Glenn T. Seaborg, who last year became the first living scientist to have an element named for him, has been honored again, this time with the establishment of the Glenn T. Seaborg Chair in Physical Chemistry at the University of California, Berkeley. The Chair was created through a generous endowment in tribute to Seaborg and the College of Chemistry. Endowed chairs, which provide a source of income to advance the scholarly activities of the appointed professor, also are one of the highest forms of campus recognition that a faculty member can receive. Alexander Pines, who has significantly advanced the field of nuclear magnetic resonance (NMR) spectroscopy, has been named to hold the Seaborg Chair. "It is a privilege indeed to be thus associated with my legendary colleague and good friend Glenn Seaborg," Pines says. "It is especially fitting that Glenn Seaborg, who has received the highest awards of the international and national scientific communities, be thus recognized at the institution where he earned his doctorate and where he has spent most of his career," said College of Chemistry Dean Alexis T. Bell. "We are enormously grateful to our anonymous benefactors." Bell added, "We anticipate that we will be able to recognize other distinguished faculty members as additional chairs are established in the future." Seaborg earned his Ph.D.
