Donna Strickland '89 (Phd), a Self-Described “Laser Jock,” Receives
Donna Strickland ’89 (PhD), a self-described “laser jock,” receives the Nobel Prize, along with her advisor, Gérard Mourou, for work they did at the Laboratory for Laser Energetics. By Lindsey Valich Donna Strickland ’89 (PhD) still recalls the visit she took to the On- tario Science Centre when she was a child growing up in the town of Guelph, outside Toronto. Her father pointed to a laser display. “ ‘Donna, this is the way of the future,’ ” Strickland remembers him telling her. Lloyd Strickland, an electrical engineer, along with Donna’s moth- er, sister, and brother, was part of the family that “continually sup- ported and encouraged me through all my years of education,” Donna Strickland wrote in the acknowledgments of her PhD thesis, “De- velopment of an Ultra-Bright Laser and an Application to Multi- Photon Ionization.” She was captivated by that laser display. And since then, she says, “I’ve always thought lasers were cool.” Her passion for laser science research and her commitment to be- ing a “laser jock,” as she has called herself, has led her across North America, from Canada to the United States and back again. But it’s the work that she did as a graduate student at Rochester in the 1980s that has earned her the remarkable accolade of Nobel Prize laureate. When Strickland entered the University’s graduate program in op- tics, laser physicists were grappling with a thorny problem: how could they create ultrashort, high-intensity laser pulses that wouldn’t de- stroy the very material the laser was used to explore in the first place? Working with former Rochester engineering professor Gérard Mourou, Strickland developed and made workable a method to over- come the barrier. -

Simple infections, earaches, menial operations, and diseases, like syphilis and pneumonia, would possibly all end fatally, shortening the life expectancy of the population, affecting everything from family-size and marriage to retirement plans and insurance policies. So how did this “wonder drug” come into existence and who is behind the development of penicillin? The majority of the population has heard the “Eureka!” story of Alexander Fleming and his famous petri dish with the unusual mold growth, Penicillium notatum. Very few realize that there are not only different variations of the Fleming discovery but that there are also other people who were vitally important to the development of penicillin as an effective drug. -
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]. -
Cave Archaeology and the NSS: 1941–2006
George Crothers, P. Willey, and Patty Jo Watson – Cave archaeology and the NSS: 1941–2006. Journal of Cave and Karst Studies, v. 69, no. 1, p. 27–34. CAVE ARCHAEOLOGY AND THE NSS: 1941–2006 GEORGE CROTHERS1,P.WILLEY2, AND PATTY JO WATSON3 Abstract: Like most other branches of speleology, cave archaeology in the U.S. grew and developed significantly during the mid to late twentieth century. Originally viewed as marginal to mainstream Americanist archaeology, pursuit of prehistoric and historic archaeology underground is now widely accepted as making valuable contributions to knowledge of human past. The National Speleological Society played a central role in that development and continues to do so. We outline the establishment and growth of cave archaeology in North America, with special emphasis on relations between the NSS and archaeology performed in dark zone, deep cave interiors. INTRODUCTION 1920s and 1930s by ‘‘the Caveman,’’ as Neville was often called. The NSS has directly participated in cave archaeology Despite interest in cave archaeology within the NSS through cooperation, education, and conservation. Mem- governance and some portion of the membership during bers of the Society have made notable contributions to the the first few decades after the organization was formed, science by reporting the location of archaeological sites, systematic, long-term archaeological research by pro- participating in their investigation, and by equipping fessional archaeologists in the dark zones of big caves in scientists with the techniques and technology needed to the Americas did not get underway until the 1960s.

Chirped Pulse Amplification, CPA, Was Both Simple and Elegant
THE NOBEL PRIZE IN PHYSICS 2018 POPULAR SCIENCE BACKGROUND Tools made of light The inventions being honoured this year have revolutionised laser physics. Extremely small objects and incredibly fast processes now appear in a new light. Not only physics, but also chemistry, biology and medicine have gained precision instruments for use in basic research and practical applications. Arthur Ashkin invented optical tweezers that grab particles, atoms and molecules with their laser beam fingers. Viruses, bacteria and other living cells can be held too, and examined and manipulated without being damaged. Ashkin’s optical tweezers have created entirely new opportunities for observing and controlling the machinery of life. Gérard Mourou and Donna Strickland paved the way towards the shortest and most intense laser pulses created by mankind. The technique they developed has opened up new areas of research and led to broad industrial and medical applications; for example, millions of eye operations are performed every year with the sharpest of laser beams. Travelling in beams of light Arthur Ashkin had a dream: imagine if beams of light could be put to work and made to move objects. In the cult series that started in the mid-1960s, Star Trek, a tractor beam can be used to retrieve objects, even asteroids in space, without touching them. Of course, this sounds like pure science fic- tion. We can feel that sunbeams carry energy – we get hot in the sun – although the pressure from the beam is too small for us to feel even a tiny prod. But could its force be enough to push extremely tiny particles and atoms? Immediately after the invention of the first laser in 1960, Ashkin began to experiment with the new instrument at Bell Laboratories outside New York. -

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.
