  • A Time of Great Growth
    Newsletter | Spring 2019 A Time of Great Growth Heartfelt greetings from the UC Riverside Department of Physics and Astronomy. This is our annual newsletter, sent out each Spring to stay connected with our former students, retired faculty, and friends in the wider community. The Department continues to grow, not merely in size but also in stature and reputation. For the 2018-2019 academic year, we were pleased to welcome two new faculty: Professors Thomas Kuhlman and Barry Barish. Professor Kuhlman was previously on the faculty at the University of Illinois at Urbana-Champaign. He joins our efforts in the emerging field of biophysics. His research lies in the quantitative imaging and theoretical modeling of biological systems. He works on genome dynamics, quantification of the activity of transposable elements in living cells, and applications to the engineering of genome editing. Professor Barry Barish, who joins us from Caltech, is the winner of the 2017 Nobel Prize in Physics. He brings great prestige to our Department. Along with Professor Richard Schrock of the Department of Chemistry, who also joined UCR in 2018, UCR now has two Nobel Prize winners on its faculty. Professor Barish is an expert on the detection and physics of gravitational waves. He has been one of the key figures in the conception, construction, and operation of the LIGO detector, where gravitational waves were first discovered in 2015, and which led to his Nobel Prize. He is a member of the National Academy of Sciences and the winner of many other prestigious awards. The discovery of gravitational waves is one of the most exciting developments in physics so far this century.

  • Mr. Jeffery Morehouse Executive Director, Bring Abducted Children Home and Father of a Child Kidnapped to Japan
    Mr. Jeffery Morehouse Executive Director, Bring Abducted Children Home and Father of a Child Kidnapped to Japan House Foreign Affairs Committee Monday, December 10, 2018 Reviewing International Child Abduction Thank you to Chairman Smith and the committee for inviting me here to share my expertise and my personal experience on the ongoing crisis and crime of international parental child abduction in Japan. Japan is internationally known as a black hole for child abduction. There have been more than 400 U.S. children kidnapped to Japan since 1994. To date, the Government of Japan has not returned a single American child to an American parent. Bring Abducted Children Home is a nonprofit organization dedicated to the immediate return of internationally abducted children being wrongfully detained in Japan and strives to end Japan's human rights violation of denying children unfettered access to both parents. We also work with other organizations on the larger goal of resolving international parental child abduction worldwide. We are founding partners in The Coalition to End International Parental Child Abduction uniting organizations to work passionately to end international parental kidnapping of children through advocacy and public policy reform. At the beginning of this year The G7 Kidnapped to Japan Reunification Project formed as an international alliance of partners who are parents and organizations from several countries including Canada, France, Germany, Italy, Japan, the United Kingdom, and the United States. The objective is to bring about a rapid resolution to this crisis affecting the human rights of thousands of children abducted to or within Japan. Many Japanese citizens and officials have shared with me that they are deeply ashamed of these abductions and need help from the U.S.

  • Professor Helen Quinn
    Professor Helen Quinn Helen Quinn was born in Australia and grew up in the Melbourne suburbs of Blackburn and Mitcham. She attended Tintern Girls Grammar School in Ringwood East. She matriculated successfully and obtained a cadetship from the Australian Department of Meteorology to fund her studies at the University of Melbourne. After beginning her undergraduate studies at the University, her family migrated to San Francisco in the early 1960s. Professor Quinn finished her undergraduate, and eventually graduate education at Stanford University. After receiving her doctorate from Stanford in 1967, she held a postdoctoral position at Deutsches Elektronen Synchrotron in Hamburg, Germany, then served as a research fellow at Harvard in 1971, joining the faculty there in 1972. She returned to Stanford in 1976 as a visitor on a Sloan Fellowship and joined the staff at the Stanford Linear Accelerator Centre (SLAC) in 1977. In her current position as a theoretical physicist at the Stanford Linear Accelerator Center (SLAC), Professor Quinn has made important contributions towards unifying the strong, weak and electromagnetic interactions into a single coherent model of particle physics. In 2000 she was awarded the Dirac Medal and Prize for pioneering contributions to the quest for a unified theory of quarks and leptons and of the strong, weak, and electromagnetic interactions. The award, shared with Professors Howard Georgi of Harvard and Jogesh Pati of the University of Maryland, recognized Professor Quinn for her work on the unification of the three interactions, and for fundamental insights about charge-parity conservation. She has also recently developed basic analysis methods used to search for the origin of particle-antiparticle asymmetry in nature.

  • Ripples in Spacetime
    editorial Ripples in spacetime The 2017 Nobel prize in Physics has been awarded to Rainer Weiss, Barry C. Barish and Kip S. Thorne “for decisive contributions to the LIGO detector and the observation of gravitational waves”. It is, frankly, difficult to find something original to say about the detection of gravitational waves that hasn’t been said already. The technological feat of measuring fluctuations in the fabric of spacetime less than one-thousandth the width of an atomic nucleus is quite simply astonishing. The scientific achievement represented by the confirmation of a century-old prediction by Albert Einstein is unique. And the collaborative effort that made the discovery possible — the Laser Interferometer Gravitational-Wave Observatory (LIGO) — is inspiring. Adapted from Phys. Rev. Lett. 116, 061102 (2016), under Creative Commons Licence. Rainer Weiss and Kip Thorne were, along with the late Ronald Drever, founders of the project that eventually became known Barry Barish, who was the director Last month we received a spectacular as LIGO.

    Lasers at 50: Byer The History of Lasers at Stanford Group Robert L. Byer Applied Physics Stanford University [email protected] Abstract In the fifty years since the demonstration of the laser, coherent light has changed the way we work, communicate and play. The generation and control of light is critical for meeting important challenges of the 21st century from fundamental science to the generation of energy.

Over 200 users came to SLAC from around the world for a discussion about the science and politics of high energy physics (HEP).
