THE COSMIC COCKTAIL Three Parts Dark Matter
release For immediate release Contact: Andrew DeSio Publication Date: June 11, 2014 (609) 258-5165 [email protected] Weaving a tale of scientific discovery, adventures in cosmology, and the hunt for dark matter, Dr. Katherine Freese explores just what exactly the universe is made out of in THE COSMIC COCKTAIL Three Parts Dark Matter “Freese tells her trailblazing and very personal story of how the worlds of particle physics and astronomy have come together to unveil the mysterious ingredients of the cosmic cocktail that we call our universe.” Brian Schmidt, 2011 Nobel Laureate in Physics, Australian National University What is dark matter? Where is it? Where did it come from? How do scientists study the stuff when they can’t see it? According to current research, our universe consists of only 5% ordinary matter (planets, comets, galaxies) while the rest is made of dark matter (26%) and dark energy (69%). Scientists and researchers are hard at work trying to detect these mysterious phenomena. And there are none further ahead in the pursuit than Dr. Katherine Freese, one of today’s foremost pioneers in the study of dark matter. In her splendidly written new book THE COSMIC COCKTAIL: Three Parts Dark Matter (Publication Date: June 11, 2014; $29.95), Dr. Freese tells the inside story of the epic quest to solve one of the most compelling enigmas of modern science—what is the universe made of? Blending cutting-edge science with her own behind-the-scenes insights as a leading researcher in the field, acclaimed theoretical physicist Katherine Freese recounts the hunt for dark matter, from the predictions and discoveries of visionary scientists like Fritz Zwicky— the Swiss astronomer who coined the term "dark matter" in 1933—to the deluge of data today from underground laboratories, satellites in space, and the Large Hadron Collider. -

Asian Nobel Prize' for Mapping the Universe 27 May 2010
Scientists win 'Asian Nobel Prize' for mapping the universe 27 May 2010 Three US scientists whose work helped map the category. universe are among the recipients of the one- million-US-dollar Shaw Prize, known as the "Asian (c) 2010 AFP Nobel," the competition's organisers said Thursday. Princeton University professors Lyman Page and David Spergel and Charles Bennett of Johns Hopkins University, won the award for an experiment that helped to determine the "geometry, age and composition of the universe to unprecedented precision." The trio will share the Shaw Prize's award for astronomy, with one-million-US-dollar prizes also awarded in the categories for mathematical sciences and life sciences and medicine. The University of California's David Julius won the award for life sciences and medicine for his "seminal discoveries" of how the skin senses pain and temperature, the organisers' statement said. "(Julius's) work has provided insights into fundamental mechanisms underlying the sense of touch as well as knowledge that opens the door to rational drug design for the treatment of chronic pain," the statement said. Princeton's Jean Bourgain won an award for his "profound work" in mathematical sciences, it said. The Shaw Prize, funded by Hong Kong film producer and philanthropist Run Run Shaw and first awarded in 2004, honours exceptional contributions "to the advancement of civilization and the well-being of humankind." The awards will be presented at a ceremony in Hong Kong on September 28. Last year, two scientists whose work challenged the assumption that obesity is caused by a lack of will power won the life sciences and medicine 1 / 2 APA citation: Scientists win 'Asian Nobel Prize' for mapping the universe (2010, May 27) retrieved 27 September 2021 from https://phys.org/news/2010-05-scientists-asian-nobel-prize-universe.html This document is subject to copyright. -

The Curse of Cash Kenneth S. ROGOff The world is drowning in cash—and it’s making us poorer and less safe. In The Curse of Cash, Kenneth Rogoff, one of the world’s leading economists, makes a persuasive and fascinating case for an idea that until recently would have seemed outlandish: getting rid of most paper money. Even as people in advanced economies are using less paper money, there is more cash in circulation—a record $1.4 trillion in U.S. dollars alone, or $4,200 for every American, mostly in $100 One of the world’s leading bills. And the United States is hardly exceptional. So what is all that economists on why it’s time to cash being used for? The answer is simple: a large part is feeding get rid of most paper money tax evasion, corruption, terrorism, the drug trade, human trafficking, and the rest of a massive global underground economy. As Rogoff shows, paper money can also cripple monetary policy. In the aftermath of the recent financial crisis, central banks “Highly engaging, thought-provoking, have been unable to stimulate growth and inflation by cutting inter- and persuasive, The Curse of Cash est rates significantly below zero for fear that it would drive investors makes the case that time is running to abandon treasury bills and stockpile cash. This constraint has out for paper money. As Kenneth paralyzed monetary policy in virtually every advanced economy, and Rogoff has done before, this book is likely to be a recurring problem in the future. sets the standard on a problem that The Curse of Cash offers a plan for phasing out paper money will only become more important; it and addresses the issues the transition will pose, ranging from fears is also sure to influence discussions about privacy and price stability to the need to provide subsidized about the ability of central banks to debit cards for the poor. -

David Spergel Is the Director of the Center for Computational Astrophysics and the Charles Young Professor of Astronomy at Princeton University
David Spergel is the director of the Center for Computational Astrophysics and the Charles Young Professor of Astronomy at Princeton University. He is the former chair of the Space Studies Board. Using microwave background observations from the Wilkinson Microwave Anisotropy Probe (WMAP) and the Atacama Cosmology Telescope, Spergel has measured the age, shape and composition of the universe. These observations have played a significant role in establishing the standard model of cosmology. He is one of the leaders of the Simons Observatory, which will include a planned millimeter-wave telescope that will allow us to take the next step in studying the microwave sky and probing the history of the universe. Spergel is currently co-chair of the Wide Field Infrared Survey Telescope (WFIRST) science team. WFIRST will study the nature of dark energy, complete the demographic survey of extrasolar planets, characterize the atmospheres of nearby planets and survey the universe with more than 100 times the field of view of the Hubble Space Telescope. Spergel has played a significant role in designing the coronagraph and in shaping the overall mission. Since completing my Ph.D. work, Spergel has been interested in using laboratory experiments and astronomical observations to probe the nature of dark matter and look for new physics. Recently, Spergel has been active in the exploration of data from the Gaia satellite and observations made by Subaru’s Hyper Suprime-Cam. Spergel serves as co-chair of the Global Coordination of Ground and Space Astrophysics working group of the International Astronomical Union. At Princeton, Spergel was department chair for a decade. -

The book Welcome to the Universe 1st edition contains a multitude of pictures, diagrams and illustrations, and while you can download these as a PDF, that won't be of use to you if like me you like to listen while out and about or driving. Inspired by the enormously popular introductory astronomy course that Neil deGrasse Tyson, Michael A. Just how sure are scientists of this? It was published inand it was a major non-fiction bestseller. Strauss takes over as the main author for the second section on Galaxies. I found that this occasionally required re-reading passages to pick up on the nuances. There are no discussion topics on this book Welcome to the Universe 1st edition. I don't need multiple pages explaining the evolution of an equation, but would rather be told how things were related, and move on to the discussion of the idea. If the chalk smithereen is the proton, would the atom be as big as a beach ball? This is partly because it is hard, and partly because while the book recovers lots of high school physics, it doesn't discuss magnetism at much depth, and these concepts come in very handy to follow the more detailed work. -
Small-Scale Anisotropies of the Cosmic Microwave Background: Experimental and Theoretical Perspectives
Small-Scale Anisotropies of the Cosmic Microwave Background: Experimental and Theoretical Perspectives Eric R. Switzer A DISSERTATION PRESENTED TO THE FACULTY OF PRINCETON UNIVERSITY IN CANDIDACY FOR THE DEGREE OF DOCTOR OF PHILOSOPHY RECOMMENDED FOR ACCEPTANCE BY THE DEPARTMENT OF PHYSICS [Adviser: Lyman Page] November 2008 c Copyright by Eric R. Switzer, 2008. All rights reserved. Abstract In this thesis, we consider both theoretical and experimental aspects of the cosmic microwave background (CMB) anisotropy for ℓ > 500. Part one addresses the process by which the universe first became neutral, its recombination history. The work described here moves closer to achiev- ing the precision needed for upcoming small-scale anisotropy experiments. Part two describes experimental work with the Atacama Cosmology Telescope (ACT), designed to measure these anisotropies, and focuses on its electronics and software, on the site stability, and on calibration and diagnostics. Cosmological recombination occurs when the universe has cooled sufficiently for neutral atomic species to form. The atomic processes in this era determine the evolution of the free electron abundance, which in turn determines the optical depth to Thomson scattering. The Thomson optical depth drops rapidly (cosmologically) as the electrons are captured. The radiation is then decoupled from the matter, and so travels almost unimpeded to us today as the CMB. Studies of the CMB provide a pristine view of this early stage of the universe (at around 300,000 years old), and the statistics of the CMB anisotropy inform a model of the universe which is precise and consistent with cosmological studies of the more recent universe from optical astronomy.
