  • Appendix I Lunar and Martian Nomenclature
    APPENDIX I LUNAR AND MARTIAN NOMENCLATURE LUNAR AND MARTIAN NOMENCLATURE A large number of names of craters and other features on the Moon and Mars, were accepted by the IAU General Assemblies X (Moscow, 1958), XI (Berkeley, 1961), XII (Hamburg, 1964), XIV (Brighton, 1970), and XV (Sydney, 1973). The names were suggested by the appropriate IAU Commissions (16 and 17). In particular the Lunar names accepted at the XIVth and XVth General Assemblies were recommended by the 'Working Group on Lunar Nomenclature' under the Chairmanship of Dr D. H. Menzel. The Martian names were suggested by the 'Working Group on Martian Nomenclature' under the Chairmanship of Dr G. de Vaucouleurs. At the XVth General Assembly a new 'Working Group on Planetary System Nomenclature' was formed (Chairman: Dr P. M. Millman) comprising various Task Groups, one for each particular subject. For further references see: [AU Trans. X, 259-263, 1960; XIB, 236-238, 1962; Xlffi, 203-204, 1966; xnffi, 99-105, 1968; XIVB, 63, 129, 139, 1971; Space Sci. Rev. 12, 136-186, 1971. Because at the recent General Assemblies some small changes, or corrections, were made, the complete list of Lunar and Martian Topographic Features is published here.

  • Remembering Dr. Homi Jehangir Bhabha, FR S (October 30
    Remembering Dr. Homi Jehangir Bhabha, F. R. S (October 30, 1909 – January 24, 1966) Dr. Bhabha in deep thought Dr. Homi Jehangir Bhabha enriched India in its post Independence days for more than 2 decades with his pioneering scientific ideas and brilliant administration leading to the building of two most prominent institutions in India, the Tata Institute of Fundamental Research (TIFR) and the Atomic Energy Commission (AEC), the two institutions that stand as leading pinnacles in science, the crowning achievements of human endeavor. Remember that these were built soon after the Independence when we have had minimum facilities in the universities and colleges to even hold classes. Note also the emphasis on Fundamental Research, one that Dr. Bhabha placed on the character of research. Dr. Bhabha left us more than 4 decades ago, yet we remember him very clearly as if we have had been with him all this time. This is manifestly so, because by his virtuous philanthropy and clear actions he changed the scene of Indian science, and also changed all of us in this process. To achieve his philosophy, a highly successful scientist that he was, he sacrificed his personal scientific career to spend most of his time to grow India. We have today a million reasons to remember him for his contributions. More importantly, we owe him an immense debt of gratitude for what he did to India’s science, technology and education. In the field of science, he changed an underdeveloped country into a very developed country by his actions within a period of about 25 years.

  • Dissertation Calibration of the Pierre Auger Observatory Fluorescence
    Dissertation Calibration of the Pierre Auger Observatory Fluorescence Detectors and the Effect on Measurements Submitted by Ben Gookin Department of Physics In partial fulfillment of the requirements For the Degree of Doctor of Philosophy Colorado State University Fort Collins, Colorado Summer 2015 Doctoral Committee: Advisor: John Harton Walter Toki Kristen Buchanan Carmen Menoni Copyright by Ben Gookin 2015 All Rights Reserved Abstract Calibration of the Pierre Auger Observatory Fluorescence Detectors and the Effect on Measurements The Pierre Auger Observatory is a high-energy cosmic ray observatory located in Malarg¨ue, Mendoza, Argentina. It is used to probe the highest energy particles in the Universe, with energies greater than 1018 eV, which strike the Earth constantly. The observatory uses two techniques to observe the air shower initiated by a cosmic ray: a surface detector composed of an array of more than 1600 water Cherenkov tanks covering 3000 km2, and 27 nitrogen fluorescence telescopes overlooking this array. The Cherenkov detectors run all the time and therefore have high statistics on the air showers. The fluorescence detectors run only on clear moonless nights, but observe the longitudinal development of the air shower and make a calorimetric measure of its energy. The energy measurement from the the fluorescence detectors is used to cross calibrate the surface detectors, and makes the measurements made by the Auger Observatory surface detector highly model-independent. The calibration of the fluorescence detectors is then of the utmost importance to the measurements of the Ob- servatory. Described here are the methods of the absolute and multi-wavelength calibration of the fluorescence detectors, and improvements in each leading to a reduction in calibration uncertainties to 4% and 3.5%, respectively.

  • Radioactivity and X-Rays
    Radioactivity and X-rays Applications and health effects by Thormod Henriksen Preface The present book is an update and extension of three previous books from groups of scientists at the University of Oslo. The books are: I. Radioaktivitet – Stråling – Helse Written by; Thormod Henriksen, Finn Ingebretsen, Anders Storruste and Erling Stranden. Universitetsforlaget AS 1987 ISBN 82-00-03339-2 I would like to thank my coauthors for all discussions and for all the data used in this book. The book was released only a few months after the Chernobyl accident. II. Stråling og Helse Written by Thormod Henriksen, Finn Ingebretsen, Anders Storruste, Terje Strand, Tove Svendby and Per Wethe. Institute of Physics, University of Oslo 1993 and 1995 ISBN 82-992073-2-0 This book was an update of the book above. It has been used in several courses at The University of Oslo. Furthermore, the book was again up- dated in 1998 and published on the Internet. The address is: www.afl.hitos.no/mfysikk/rad/straling_innh.htm III. Radiation and Health Written by Thormod Henriksen and H. David Maillie Taylor & Francis 2003 ISBN 0-415-27162-2 This English written book was mainly a translation from the books above. I would like to take this opportunity to thank David for all help with the translation. The three books concentrated to a large extent on the basic properties of ionizing radiation. Efforts were made to describe the background ra- diation as well as the release of radioactivity from reactor accidents and fallout from nuclear explosions in the atmosphere. These subjects were of high interest in the aftermath of the Chernobyl accident.

  • A Nature of Science Guided Approach to the Physics Teaching of Cosmic Rays
    A Nature of Science guided approach to the physics teaching of Cosmic Rays Dissertation zur Erlangung des akademischen Grades Doktorin der Philosophie (Dr. phil. { Doctor philosophiae) eingereicht am Fachbereich 4 Mathematik, Naturwissenschaften, Wirtschaft & Informatik der Universit¨atHildesheim vorgelegt von Rosalia Madonia geboren am 20. August 1961 in Palermo 2018 Schwerpunkt der Arbeit: Didaktik der Physik Tag der Disputation: 21 Januar 2019 Dekan: Prof. Dr. M. Sauerwein 1. Gutachter: Prof. Dr. Ute Kraus 2. Gutachter: Prof. Dr. Peter Grabmayr ii Abstract This thesis focuses on cosmic rays and Nature of Science (NOS). The first aim of this work is to investigate whether the variegated aspects of cosmic ray research -from its historical development to the science topics addressed herein- can be used for a teaching approach with and about NOS. The efficacy of the NOS based teaching has been highlighted in many studies, aimed at developing innovative and more effective teaching strategies. The fil rouge that we propose unwinds through cosmic ray research, that with its century long history appears to be the perfect topic for a study of and through NOS. The second aim of the work is to find out what knowledge the pupils and students have regarding the many aspect of NOS. To this end we have designed, executed, and analyzed the outcomes of a sample-based investigation carried out with pupils and students in Palermo (Italy), T¨ubingenand Hildesheim (Germany), and constructed around an open-ended ques- tionnaire. The main goal is to study whether intrinsic differences between the German and Italian samples can be observed. The thesis is divided in three parts.
