This award recognizes educators who have made notable and creative contributions to the teaching of physics. Regarding her selection to receive the 2021 Klopsteg Award Czerski said, “I’m very grateful to the AAPT for recognizing my work in this way. It’s always been a mystery to me that physics at school has sometimes had such a bad reputation when it’s all about playing with and understanding the world around us. What could be more fun? Everyone who looks closely at their daily lives will see all sorts of fascinating mechanisms, and Helen Czerski it’s always been a joy to help change the way people see their world.” An Ocean of Czerski is a physicist, first and foremost, but she’s acquired a few other labels along the way: oceanographer, Physics presenter, author, and bubble enthusiast. She grew up near Manchester, in northwest England, and spent her childhood playing by the canals and along the old railway routes of the early Industrial Revolution. She studied Natural Sciences (Physics) at Churchill College, Cambridge, finishing with a first class degree. A year later, she returned to Cambridge to study for a PhD in experimental explosives physics, motivated by the op- Saturday, July 31 portunity to use high-speed photography to explore the physical world further. 11 a.m.–12 p.m. After her PhD, she looked for a pathway that would allow her to continue to build that sort of experiment, but with an application in the natural world. That’s when she found out about bubbles and oceans. The Scripps Institution of Oceanography in San Diego was her door into that world, followed by a postdoc at the Graduate School of Oceanog- ABSTRACT: When the Apollo astronauts travelled to the raphy in Rhode Island. She returned to the Moon, the most memorable photograph they took was UK to start her own research program on of the “Blue Marble”: the view of Earth from space.

This talk will be about the physics of the ocean, and the perspective on our planet that we get from exploring it. Czerski gets particularly excited about Zooming in from the very large, we’ll get to the very small: the physics of the everyday world and the the breaking waves and bubbles that are found at the oceans. The oceans are the heart of the ocean surface. These bubbles help the ocean breathe, and Earth’s engine, the system of atmosphere, my research is focused on understanding how they form, rocks, ice, life and ocean that makes up our and how they help that breathing process.

Upon her return to the UK from Rhode Island, she became a regular science presenter for BBC, in addition to her academic work. Since 2017, her column “Everyday Physics” has been a regular feature in the Wall Street Journal. Her book, Storm in a Tea- cup: The Physics of Everyday Life, published by W. W. Norton Company, received rave reviews from the New York Times, Wall Street Journal, The Guardian, and others. Named for Paul E. Klopsteg, a principal founder, a former AAPT President, and a long-time mem- ber of AAPT, the Klopsteg Memorial Lecture Award recognizes outstanding communication of the excitement of contemporary physics to the general public. The recipient delivers the Klopsteg Lecture at an AAPT Summer Meeting on a topic of current significance and at a level suitable for a non-specialist audience and receives a monetary award, an Award Certificate, and travel expenses to the meeting. The award was established in 1990. 8 2021 AAPT Summer Meeting enhancing the understanding and appreciation of physics through teaching AAPT makes me a better teacher, but it’s more complicated than that. AAPT provides a forum not only for improvement but for questioning our practice. Attending an AAPT meeting inspired two other teachers and myself to start EnergyTeachers.org.

    Aspects of Black Hole Physics Andreas Vigand Pedersen The Niels Bohr Institute Academic Advisor: Niels Obers e-mail: [email protected] Abstract: This project examines some of the exact solutions to Einstein’s theory, the theory of linearized gravity, the Komar definition of mass and angular momentum in general relativity and some aspects of (four dimen- sional) black hole physics. The project assumes familiarity with the basics of general relativity and differential geometry, but is otherwise intended to be self contained. The project was written as a ”self-study project” under the supervision of Niels Obers in the summer of 2008.

    DOSSIÊS MODELS AND THE DYNAMICS OF THEORIES Paulo Abrantes Universidade de Brasília [email protected] Abstract: This paper gives a historical overview of the ways various trends in the philosophy of science dealt with models and their relationship with the topics of heuristics and theoretical dynamics. First of all, N. Campbell’s account of analogies as components of scientific theories is presented. Next, the notion of ‘model’ in the reconstruction of the structure of scientific theories proposed by logical empiricists is examined. This overview finishes with M. Hesse’s attempts to develop Campbell’s early ideas in terms of an analogical inference. The final part of the paper points to contemporary developments on these issues which adopt a cognitivist perspective. It is indicated how discussions in the cognitive sciences might help to flesh out some of the insights philosophers of science had concerning the role models and analogies play in actual scientific theorizing. Key words: models, analogical reasoning, metaphors in science, the structure of scientific theories, theoretical dynamics, heuristics, scientific discovery. Hesse (1976) suggests that different philosophical explications of the roles models play in science correspond to different models of science. As a matter of fact, the explication of scientific modeling became a central issue in the criticism and revision of logical empiricism in the 50’s and the 60’s. The critics of the logical empiricist explication of models pointed out that it doesn’t capture one of the roles models play in science: that of providing guidelines for the development of theories.1 PHILÓSOPHOS 9 (2) : 225-269, jul./dez.

    A Brief Tour Into the History of Gravity: from Emocritus to Einstein

    American Journal of Space Science 1 (1): 33-45, 2013 ISSN: 1948-9927 © 2013 Science Publications doi:10.3844/ajssp.2013.33.45 Published Online 1 (1) 2013 (http://www.thescipub.com/ajss.toc) A Brief Tour into the History of Gravity: From Emocritus to Einstein Panagiotis Papaspirou and Xenophon Moussas Department of Physics, Section of Astrophysics, Astronomy and Mechanics, University of Athens, Athens, Greece ABSTRACT The History of Gravity encompasses many different versions of the idea of the Gravitational interaction, which starts already from the Presocratic Atomists, continues to the doctrines of the Platonic and Neoplatonic School and of the Aristotelian School, passes through the works of John Philoponus and John Bouridan and reaches the visions of Johannes Kepler and Galileo Galilei. Then, the major breakthrough in the Theory of Motion and the Theory of Gravity takes place within the realm of Isaac Newton’s most famous Principia and of the work of Gottfried Leibniz, continues with the contributions of the Post- newtonians, such as Leonhard Euler, reaches the epoch of its modern formulation by Ernst Mach and other Giants of Physics and Philosophy of this epoch, enriches its structure within the work of Henry Poincare and finally culminates within the work of Albert Einstein, with the formulation of the Theory of Special Relativity and of General Relativity at the begin of the 20th century. The evolution of the Theory of General Relativity still continues up to our times, is rich in forms it takes and full of ideas of theoretical strength. Many fundamental concepts of the Epistemology and the History of Physics appear in the study of the Theory of Gravity, such as the notions of Space, of Time, of Motion, of Mass, in its Inertial, Active Gravitational and Passive Gravitational form, of the Inertial system of reference, of the Force, of the Field, of the Riemannian Geometry and of the Field Equations.

    SNSD and the Art of Bridging The

    Situations Vol. 3 (Winter 2009) © 2009 by Yonsei University Mariah Junglan Min1 [email protected] The Art of Crossing the Line Although the intensive coverage provided to the new all-boy and all-girl bands through the Internet and in more traditional media such as television may make it seem as though such they have long dominated popular music, the current explosion in popularity of idol groups begun only two years ago. What is more, this is not the first time that such groups have stormed the K-pop charts. The first wave of massively popular idol groups was in the late 90s, when a veritable army of teens made their debut as singers. Korean multi-entertainment companies recognized the business potential in well-trained young and attractive stars, and the feverish reception from the public confirmed this. The result was that H.O.T., Sechs Kies, Shinhwa, Fin.K.L., S.E.S., and G.O.D. enjoyed chart success and outstanding album sales. Around 2002, this first golden age of idol groups came to an end. Most of the first wave of idols split up, while some individual members went on to pursue solo careers. Although some groups did continue, with Shinhwa performing as recently as 2008, the moment of the idol group seemed to have passed. For a short time, the K-pop scene was now host to a series of successful solo artists, such as Rain and Yi Hyo-ri, the latter a former member of the all-girl band Fin.K.L. In 2004, the first forerunners of the second wave began to appear, with TVXQ, for example, releasing their first single that year.

    The Globalization of K-Pop: the Interplay of External and Internal Forces

    THE GLOBALIZATION OF K-POP: THE INTERPLAY OF EXTERNAL AND INTERNAL FORCES Master Thesis presented by Hiu Yan Kong Furtwangen University MBA WS14/16 Matriculation Number 249536 May, 2016 Sworn Statement I hereby solemnly declare on my oath that the work presented has been carried out by me alone without any form of illicit assistance. All sources used have been fully quoted. (Signature, Date) Abstract This thesis aims to provide a comprehensive and systematic analysis about the growing popularity of Korean pop music (K-pop) worldwide in recent years. On one hand, the international expansion of K-pop can be understood as a result of the strategic planning and business execution that are created and carried out by the entertainment agencies. On the other hand, external circumstances such as the rise of social media also create a wide array of opportunities for K-pop to broaden its global appeal. The research explores the ways how the interplay between external circumstances and organizational strategies has jointly contributed to the global circulation of K-pop. The research starts with providing a general descriptive overview of K-pop. Following that, quantitative methods are applied to measure and assess the international recognition and global spread of K-pop. Next, a systematic approach is used to identify and analyze factors and forces that have important influences and implications on K-pop’s globalization. The analysis is carried out based on three levels of business environment which are macro, operating, and internal level. PEST analysis is applied to identify critical macro-environmental factors including political, economic, socio-cultural, and technological.

Druckjahr 2021 Referent: Prof. Dr. Mathias Frisch Korreferent: Prof. Dr. Torsten Wilholt Tag der Promotion: 26.10.2020 2 To my early died sister Uta 3 Acknowledgements I could quote only very few by name who have contributed to my work on this thesis, for discussing some of the developed ideas with me or comments on parts of my manuscript. These are in the first place my advisor Mathias Frisch and further Torsten Wilholt, who read critically individual chapters. Much more have contributed by some remarks or ideas mentioned in passing which I cannot assign to someone explicitly and therefore must be left unnamed. Also, other people not named here have supported my work in the one or other way. I think they know who were meant if they read this. A lot of thanks are due to Zoe Vercelli from the International Writing centre at Leibniz University Hannover improving my English at nearly the whole manuscript (some parts are leaved to me because of organisational changes at the writing centre). So, where the English is less correct Zoe could not have had a look on it. Of course, all errors and imprecisions remain in solely my responsibility. 4 Abstract This thesis investigates what tools are appropriate for answering the question how it is possible to develop such a complex theory in physics as the standard model of particle physics with only an access via electromagnetic interaction of otherwise unobservable objects and their interactions it was investigated what the tools are to do this.
