Luis Alvarez: the Ideas Man
CERN Courier March 2012 Commemoration Luis Alvarez: the ideas man The years from the early 1950s to the late 1980s came alive again during a symposium to commemorate the birth of one of the great scientists and inventors of the 20th century. Luis Alvarez – one of the greatest experimental physicists of the 20th century – combined the interests of a scientist, an inventor, a detective and an explorer. He left his mark on areas that ranged from radar through to cosmic rays, nuclear physics, particle accel- erators, detectors and large-scale data analysis, as well as particles and astrophysics. On 19 November, some 200 people gathered at Berkeley to commemorate the 100th anniversary of his birth. Alumni of the Alvarez group – among them physicists, engineers, programmers and bubble-chamber film scanners – were joined by his collaborators, family, present-day students and admirers, as well as scientists whose professional lineage traces back to him. Hosted by the Lawrence Berkeley National Laboratory (LBNL) and the University of California at Berkeley, the symposium reviewed his long career and lasting legacy. A recurring theme of the symposium was, as one speaker put it, a “Shakespeare-type dilemma”: how could one person have accom- plished all of that in one lifetime? Beyond his own initiatives, Alvarez created a culture around him that inspired others to, as George Smoot put it, “think big,” as well as to “think broadly and then deep” and to take risks. Combined with Alvarez’s strong scientific standards and great care in execut- ing them, these principles led directly to the awarding of two Nobel Luis Alvarez celebrating the announcement of his 1968 Nobel prizes in physics to scientists at Berkeley – George Smoot in 2006 prize.

The Cosmic Microwave Background: the History of Its Experimental Investigation and Its Significance for Cosmology
REVIEW ARTICLE The Cosmic Microwave Background: The history of its experimental investigation and its significance for cosmology Ruth Durrer Universitéde Genève, Département de Physique Théorique,1211 Genève, Switzerland E-mail: [email protected] Abstract. This review describes the discovery of the cosmic microwave background radiation in 1965 and its impact on cosmology in the 50 years that followed. This discovery has established the Big Bang model of the Universe and the analysis of its fluctuations has confirmed the idea of inflation and led to the present era of precision cosmology. I discuss the evolution of cosmological perturbations and their imprint on the CMB as temperature fluctuations and polarization. I also show how a phase of inflationary expansion generates fluctuations in the spacetime curvature and primordial gravitational waves. In addition I present findings of CMB experiments, from the earliest to the most recent ones. The accuracy of these experiments has helped us to estimate the parameters of the cosmological model with unprecedented precision so that in the future we shall be able to test not only cosmological models but General Relativity itself on cosmological scales. Submitted to: Class. Quantum Grav. arXiv:1506.01907v1 [astro-ph.CO] 5 Jun 2015 The Cosmic Microwave Background 2 1. Historical Introduction The discovery of the Cosmic Microwave Background (CMB) by Penzias and Wilson, reported in Refs. [1, 2], has been a 'game changer' in cosmology. Before this discovery, despite the observation of the expansion of the Universe, see [3], the steady state model of cosmology still had a respectable group of followers.

social epistemology, 2000, vol. 14, nos. 2}3, 131–180 A public debate on the science of global warming: is there su¶ cient evidence which proves we should limit greenhouse gas emissions because of climate change? Full transcript of inaugural AARST Science Policy Forum, New York Hilton, Friday 20 November 1998, 7–9 pm. JAMES E. HANSEN (aµ rmative) PATRICK J. MICHAELS (negative) 1. Moderator’s introductory remarks Dr Gordon R. Mitchell : … You know, it’s been said that rhetoric of science is nothing more than a bunch of covert neo-Aristotelians blowing hot air. Tonight, we plan to test that hypothesis when AARST hosts a public debate about global warming. Before the evening’s arguments cool o¶ , it is our hope that some of the heat and the light produced by this debate will start to melt away a few of the doubts that the rhetoric of science enterprise is a rare ed and detached scholarly project, of little relevance to con- temporary science policy discussions … But before I lay out tonight’s debate format and introduce the participants, I want to talk brie y about the origins of this event. At last year’s AARST preconference gathering in Chicago, Michael Hyde and Steve Fuller issued a charge to those gathered in the audience. This charge basically involved a call for relevance, a plea for ‘measurable outcomes ’ and ‘public engagement ’ in rhetoric of science scholarship. This call to action resonated deeply with my own political commitments, because I believe that privileged members of the academy shoulder a double-sided obligation.

Spin-Off Successes of SETI Research at Berkeley
**FULL TITLE** ASP Conference Series, Vol. **VOLUME**, c **YEAR OF PUBLICATION** **NAMES OF EDITORS** Spin-Off Successes of SETI Research at Berkeley K. A. Douglas School of Physics, University of Exeter, Exeter, United Kingdom D. P. Anderson, R. Bankay, H. Chen, J. Cobb, E.J. Korpela, M. Lebofsky, A. Parsons, J. Von Korff, D. Werthimer Space Sciences Laboratory, University of California Berkeley, Berkeley CA, USA 94720 Abstract. Our group contributes to the Search for Extra-Terrestrial Intelligence (SETI) by developing and using world-class signal processing computers to analyze data collected on the Arecibo telescope. Although no patterned signal of extra-terrestrial origin has yet been detected, and the immediate prospects for making such a detection are highly uncertain, the SETI@home project has nonetheless proven the value of pursuing such research through its impact on the fields of distributed computing, real-time signal pro- cessing, and radio astronomy. The SETI@home project has spun off the Center for Astronomy Signal Processing and Electronics Research (CASPER) and the Berkeley Open Infrastructure for Networked Computing (BOINC), both of which are responsi- ble for catalyzing a smorgasbord of new research in scientific disciplines in countries around the world. Futhermore, the data collected and archived for the SETI@home project is proving valuable in data-mining experiments for mapping neutral galatic hy- drogen and for detecting black-hole evaporation. 1 The SETI@home Project at UC Berkeley SETI@home is a distributed computing project harnessing the power from millions of volunteer computers around the world (Anderson 2002). Data collected at the Arecibo radio telescope via commensal observations are filtered and calibrated using real-time signal processing hardware, and selectable channels are recorded to disk.

New SETI Sky Surveys for Radio Pulses
New SETI Sky Surveys for Radio Pulses Andrew Siemiona,d, Joshua Von Korffc, Peter McMahond, Eric Korpelab, Dan Werthimerb,d, David Andersonb, Geoff Bowera, Jeff Cobbb, Griffin Fostera, Matt Lebofskyb, Joeri van Leeuwena, William Mallardd, Mark Wagnerd aUniversity of California, Berkeley - Department of Astronomy, Berkeley, California bUniversity of California Berkeley - Space Sciences Laboratory, Berkeley, California cUniversity of California, Berkeley - Department of Physics, Berkeley, California dUniversity of California, Berkeley - Berkeley Wireless Research Center, Berkeley, California Abstract Berkeley conducts 7 SETI programs at IR, visible and radio wavelengths. Here we review two of the newest efforts, Astropulse and Fly’s Eye. A variety of possible sources of microsecond to millisecond radio pulses have been suggested in the last sev- eral decades, among them such exotic events as evaporating primordial black holes, hyper-flares from neutron stars, emissions from cosmic strings or perhaps extraterrestrial civilizations, but to-date few searches have been conducted capable of detecting them. The recent announcement by Lorimer et al. of the detection of a powerful (≈ 30 Jy) and highly dispersed (≈ 375 cm−3 pc) radio pulse in Parkes multi-beam survey data has fueled additional interest in such phenomena. We are carrying out two searches in hopes of finding and characterizing these uS to mS time scale dispersed radio pulses. These two observing programs are orthogonal in search space; the Allen Telescope Array’s (ATA) ”Fly’s Eye” experiment observes a 100 square degree field by pointing each 6m ATA antenna in a different direction; by contrast, the Astropulse sky survey at Arecibo is extremely sensitive but has 1/3,000 of the instantaneous sky coverage.
