Should Earth Get Demoted from Planet Status Just Like Pluto?
IOSR Journal of Applied Physics (IOSR-JAP) e-ISSN: 2278-4861.Volume 10, Issue 3 Ver. I (May. – June. 2018), PP 15-19 www.iosrjournals.org Should Earth Get Demoted From Planet Status Just Like Pluto? Dipak Nath Assistant Professor, HOD, Department of Physics, Sao Chang Govt College, Tuensang;Nagaland, India. Corresponding Author: Dipak Nath Abstract: Clyde.W. Tombough discovered Pluto on march13, 1930. From its discovery in 1930 until 2006, Pluto was classified as Planet. In the late 20th and early 21st century, many objects similar to Pluto were discovered in the outer solar system, notably the scattered disc object Eris in 2005, which is 27% more massive than Pluto. On august-24, 2006, the International Astronomical Union (IAU) defined what it means to be a Planet within the solar system. This definition excluded Pluto as a Planet added it as a member of the new category “Dwarf Planet” along with Eris and Ceres. There were many reasons why Pluto got demoted to dwarf planet status, one of which was that it couldn't clear its orbit of asteroids and other debris. But Earth's orbit is also crowded...too crowded for Earth to be a planet? Earth is indeed in a very crowded orbit, surrounded by tens of thousands of asteroids and other objects. The presence of so many asteroids seems like a serious problem for Earth's claim that it has cleared its neighborhood. And Earth isn't alone in this problem - Jupiter is surrounded by some 100,000 Trojan asteroids, and there's similar clutter around Mars and Neptune. -

Examine how diplomacy actually works in the real world. The talk will be followed by open discussion and a lively Q & A. Our Speaker: During his long career, Hugh Neighbour specialized in political and economic affairs, working on U.S. Foreign Service Officer (Retired) and Lecturer, Hugh Neighbour multilateral issues, including both arms control and human rights. Hugh's final diplomatic post was as Chief Arms Control Delegate for the U.S. at the OSCE in Vienna, responsible for conventional arms control across Europe, Central Asia, and North America. He was assigned to Germany when the Berlin Wall fell and Germany unified, to Bolivia when an uprising cut off food supplies for weeks, to Panama as General Noriega stole an election, and to Australia when the ANZUS treaty was fundamentally altered. He was stationed in London during the height of the Cold War, in Stockholm when non-aligned Sweden helped NATO intervene in Bosnia, and in the Fiji Islands where he ran U.S. relations with 8 island countries and territories. He was awarded the Secretary of State's Career Achievement Award. Prior to this, Hugh was a bridge watch officer in the U.S. Navy. After service at sea on a missile cruiser, he served ashore in the Middle East. -

Downloaded from sss.sagepub.com at UNIV OF RHODE ISLAND LIBRARY on December 9, 2013 DISCUSSION PAPER ABSTRACT Science studies has shown us why science and technology cannot always solve technical problems in the public domain. In particular, the speed of political decision-making is faster than the speed of scientific consensus formation. A predominant motif over recent years has been the need to extend the domain of technical decision-making beyond the technically qualified ´elite, so as to enhance political legitimacy. We argue, however, that the ‘Problem of Legitimacy’ has been replaced by the ‘Problem of Extension’ – that is, by a tendency to dissolve the boundary between experts and the public so that there are no longer any grounds for limiting the indefinite extension of technical decision-making rights. We argue that a Third Wave of Science Studies – Studies of Expertise and Experience (SEE) – is needed to solve the Problem of Extension. -

INTRODUCTION In the past thirty years historians have demonstrated that the ether of physics was one of the most flexible of all concepts in the natural sciences. Cantor and Hodge’s seminal collection of essays of 1981 showed how during the eighteenth and nineteenth centuries British and European natural philosophers invented a range of ethers to fulfil diverse functions from the chemical and physiological to the physical and theological.1 In religious discourse, for example, Cantor identified “animate” and spiritual ethers invented by neo-Platonists, mystics and some Anglicans to provide a mechanism for supporting their belief in Divine immanence in the cosmos; material, mechanistic and contact-action ethers which appealed to atheists and Low Churchmen because such media enabled activity in the universe without constant and direct Divine intervention; and semi-spiritual/semi-material ethers that appealed to dualists seeking a mechanism for understanding the interaction of mind and matter. 2 The third type proved especially attractive to Oliver Lodge and several other late-Victorian physicists who claimed that the extraordinary physical properties of the ether made it a possible mediator between matter and spirit, and a weapon in their fight against materialistic conceptions of the cosmos. -

RESEARCH REPORt 2010—2012 MAX-PLANCK-INSTITUT FÜR WISSENSCHAFTSGESCHICHTE Max Planck Institute for the History of Science Cover: Aurora borealis paintings by William Crowder, National Geographic (1947). The International Geophysical Year (1957–8) transformed research on the aurora, one of nature’s most elusive and intensely beautiful phenomena. Aurorae became the center of interest for the big science of powerful rockets, complex satellites and large group efforts to understand the magnetic and charged particle environment of the earth. The auroral visoplot displayed here provided guidance for recording observations in a standardized form, translating the sublime aesthetics of pictorial depictions of aurorae into the mechanical aesthetics of numbers and symbols. Most of the portait photographs were taken by Skúli Sigurdsson RESEARCH REPORT 2010—2012 MAX-PLANCK-INSTITUT FÜR WISSENSCHAFTSGESCHICHTE Max Planck Institute for the History of Science Introduction The Max Planck Institute for the History of Science (MPIWG) is made up of three Departments, each administered by a Director, and several Independent Research Groups, each led for five years by an outstanding junior scholar. Since its foundation in 1994 the MPIWG has investigated fundamental questions of the history of knowl- edge from the Neolithic to the present. The focus has been on the history of the natu- ral sciences, but recent projects have also integrated the history of technology and the history of the human sciences into a more panoramic view of the history of knowl- edge. Of central interest is the emergence of basic categories of scientific thinking and practice as well as their transformation over time: examples include experiment, ob- servation, normalcy, space, evidence, biodiversity or force. -

European Modernism and the Resident Theatre Movement: The Transformation of American Theatre between 1950 and 1970 Sarah Guthu A dissertation submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy University of Washington 2013 Reading Committee: Thomas E Postlewait, Chair Sarah Bryant-Bertail Stefka G Mihaylova Program Authorized to Offer Degree: School of Drama © Copyright 2013 Sarah Guthu University of Washington Abstract European Modernism and the Resident Theatre Movement: The Transformation of American Theatre between 1950 and 1970 Sarah Guthu Chair of the Supervisory Committee: Dr. Thomas E Postlewait School of Drama This dissertation offers a cultural history of the arrival of the second wave of European modernist drama in America in the postwar period, 1950-1970. European modernist drama developed in two qualitatively distinct stages, and these two stages subsequently arrived in the United States in two distinct waves. The first stage of European modernist drama, characterized predominantly by the genres of naturalism and realism, emerged in Europe during the four decades from the 1890s to the 1920s. This first wave of European modernism reached the United States in the late 1910s and throughout the 1920s, coming to prominence through productions in New York City. The second stage of European modernism dates from 1930 through the 1960s and is characterized predominantly by the absurdist and epic genres. Unlike the first wave, the dramas of the second wave of European modernism were not first produced in New York. Instead, these plays were often given their premieres in smaller cities across the United States: San Francisco, Seattle, Cleveland, Hartford, Boston, and New Haven, in the regional theatres which were rapidly proliferating across the United States. -
