Journal of Physics Special Topics P3_5 ALL THESE WORLDS ARE YOURS J. Bettles, I. Clarke, M. Perry and N. Pilkington. Department of Physics and Astronomy, University of Leicester, Leicester, LE1 7RH. November 03, 2011 Abstract This paper investigates a plot point of the novel 2010: Odyssey Two by Arthur C. Clarke in which self replicating monoliths engulf Jupiter, increasing its density to the point when nuclear fusion can take place, giving birth to a new star. It was found that 1.629x1020 monoliths would be needed to trigger nuclear fusion in Jupiter's core, taking 136 hours to do so. Mission Profile Anomaly 1) was stated as being 11 feet tall In the second novel of Arthur C. Clarke's (3.35m) with dimensions in the exact ratio of Space Odyssey series, 2010: Odyssey Two, a 1:4:9 (the squares of the first three integers) crew was sent to discover what went wrong for depth, width and height respectively [2]. with an earlier mission to investigate a The monolith found orbiting Jupiter, monolith (figure 1) in orbit around Jupiter. designated TMA-2 (doubly inaccurate since it Shortly after they arrived, the crew were told was neither discovered in the Tycho crater to leave as “something wonderful” was going nor did it give off any magnetic signal), had to happen. The monolith disappeared from dimensions in the exact same ratio, but was orbit and a dark spot appeared on Jupiter and 718 times bigger than TMA-1 [3]. This enabled began to grow. The spot was a population of us to calculate the dimensions of TMA-2 as monoliths that were self replicating 267.5x1070x2407m with a volume of exponentially and consuming the planet. -
Up, Up, and Away by James J
www.astrosociety.org/uitc No. 34 - Spring 1996 © 1996, Astronomical Society of the Pacific, 390 Ashton Avenue, San Francisco, CA 94112. Up, Up, and Away by James J. Secosky, Bloomfield Central School and George Musser, Astronomical Society of the Pacific Want to take a tour of space? Then just flip around the channels on cable TV. Weather Channel forecasts, CNN newscasts, ESPN sportscasts: They all depend on satellites in Earth orbit. Or call your friends on Mauritius, Madagascar, or Maui: A satellite will relay your voice. Worried about the ozone hole over Antarctica or mass graves in Bosnia? Orbital outposts are keeping watch. The challenge these days is finding something that doesn't involve satellites in one way or other. And satellites are just one perk of the Space Age. Farther afield, robotic space probes have examined all the planets except Pluto, leading to a revolution in the Earth sciences -- from studies of plate tectonics to models of global warming -- now that scientists can compare our world to its planetary siblings. Over 300 people from 26 countries have gone into space, including the 24 astronauts who went on or near the Moon. Who knows how many will go in the next hundred years? In short, space travel has become a part of our lives. But what goes on behind the scenes? It turns out that satellites and spaceships depend on some of the most basic concepts of physics. So space travel isn't just fun to think about; it is a firm grounding in many of the principles that govern our world and our universe. -
The Odyssey Collection
2001: A Space Odyssey Arthur C. Clarke Title: 2001: A space odyssey Author: Arthur C. Clarke Original copyright year: 1968 Epilogue copyright 1982 Foreword Behind every man now alive stand thirty ghosts, for that is the ratio by which the dead outnumber the living. Since the dawn of time, roughly a hundred billion human beings have walked the planet Earth. Now this is an interesting number, for by a curious coincidence there are approximately a hundred billion stars in our local universe, the Milky Way. So for every man who has ever lived, in this Universe there shines a star. But every one of those stars is a sun, often far more brilliant and glorious than the small, nearby star we call the Sun. And many - perhaps most - of those alien suns have planets circling them. So almost certainly there is enough land in the sky to give every member of the human species, back to the first ape-man, his own private, world-sized heaven - or hell. How many of those potential heavens and hells are now inhabited, and by what manner of creatures, we have no way of guessing; the very nearest is a million times farther away than Mars or Venus, those still remote goals of the next generation. But the barriers of distance are crumbling; one day we shall meet our equals, or our masters, among the stars. Men have been slow to face this prospect; some still hope that it may never become reality. Increasing numbers, however, are asking: "Why have such meetings not occurred already, since we ourselves are about to venture into space?" Why not, indeed? Here is one possible answer to that very reasonable question. -
Market Knowledge: the Philosophic Instrument Trade in Eighteenth-Century England

The instrument-maker functioned in both the realms of the philosophic elite and the burgeoning eighteenth- century public marketplace. Faced with the task of balancing the contradictory scholarly expectations of natural philosophers and the monetary pressures of the public market, these craftsmen employed sophisticated marketing strategies to reconcile these opposing realms. -
James Short and John Harrison: Personal Genius and Public Knowledge
Science Museum Group Journal James Short and John Harrison: personal genius and public knowledge Journal ISSN number: 2054-5770 This article was written by Jim Bennett 10-09-2014 Cite as 10.15180; 140209 Research James Short and John Harrison: personal genius and public knowledge Published in Autumn 2014, Issue 02 Article DOI: http://dx.doi.org/10.15180/140209 Abstract The instrument maker James Short, whose output was exclusively reflecting telescopes, was a sustained and consistent supporter of the clock and watch maker John Harrison. Short’s specialism placed his work in a tradition that derived from Newton’s Opticks, where the natural philosopher or mathematician might engage in the mechanical process of making mirrors, and a number of prominent astronomers followed this example in the eighteenth century. However, it proved difficult, if not impossible, to capture and communicate in words the manual skills they had acquired. Harrison’s biography has similarities with Short’s but, although he was well received and encouraged in London, unlike Short his mechanical practice did not place him at the centre of the astronomers’ agenda. Harrison became a small part of the growing public interest in experimental demonstration and display, and his timekeepers became objects of exhibition and resort. Lacking formal training, he himself came to be seen as a naive or intuitive mechanic, possessed of an individual and natural ‘genius’ for his work – an idea likely to be favoured by Short and his circle, and appropriate to Short’s intellectual roots in Edinburgh. The problem of capturing and communicating Harrison’s skill became acute once he was a serious candidate for a longitude award and was the burden of the specially appointed ‘Commissioners for the Discovery of Mr Harrison’s Watch’, whose members included Short. -

SIC Bibliography 15
Scientific Instrument Commission Bibliography 15 This bibliography covers the year 1998, but it also contains titles published in 1997 which only came to the compiler's notice after publication of the Fourteenth Bibliography in June 1998. In the Fourteenth Bibliography, which covered the years 1996 and 1997, no articles were included from the Bulletin of the Scientific Instrument Society and from Rittenhouse: Journal of the American Scientific Instrument Enterprise. As these journals are devoted exclusively to instruments, no reference to their contents was deemed necessary. Members of the scientific instrument community have expressed their regret over this, and in the present bibliography articles from both journals published in 1996, 1997 and 1998 have been included. The compiler is grateful to friends and colleagues who kindly sent titles for inclusion in this bibliography. Publications, or notices of publication (please with ISBN), for inclusion in the forthcoming bibliography may be sent to the SIC Secretary.

Full History of The
London Mathematical Society Historical Overview Taken from the Introduction to The Book of Presidents 1865-1965 ADRIAN RICE The London Mathematical Society (LMS) is the primary learned society for mathematics in Britain today. It was founded in 1865 for the promotion and extension of mathematical knowledge, and in the 140 years since its foundation this objective has remained unaltered. However, the ways in which it has been attained, and indeed the Society itself, have changed considerably during this time. In the beginning, there were just nine meetings per year, twenty-seven members and a handful of papers printed in the slim first volume of the ’s Society Proceedings. Today, with a worldwide membership in excess of two thousand, the LMS is responsible for numerous books, journals, monographs, lecture notes, and a whole range of meetings, conferences, lectures and symposia. The Society continues to uphold its original remit, but via an increasing variety of activities, ranging from advising the government on higher education, to providing financial support for a wide variety of mathematically-related pursuits. At the head of the Society there is, and always has been, a President, who is elected annually and who may serve up to two years consecutively. As befits a prestigious national organization, these Presidents have often been famous mathematicians, well known and respected by the mathematical community of their day; they include Cayley and Sylvester, Kelvin and Rayleigh, Hardy and Littlewood, Atiyah and Zeeman.1 But among the names on the presidential role of honour are many people who are perhaps not quite so famous today, ’t have theorems named after them, and who are largely forgotten by the majority of who don modern-day mathematicians. -
The Overlord's Burden:The Source of Sorrow in Childhood's End Matthew Candelaria
The Overlord's Burden:The Source of Sorrow in Childhood's End Matthew Candelaria In the novels of Arthur C. Clarke's most productive period, from Earthlight (1951) to Imperial Earth (1976), children appear as symbols of hope for the future. The image of the Star-Child at the end of 2001: A Space Odyssey (his collaboration with Stanley Kubrick) is imprinted on the cultural eye of humanity as we cross into the twenty-first century, and this image is emblematic of Clarke's use of children in this period. However, Clarke's most important contribution to the science-fiction genre is Childhoods End (1953), and it concludes with a very different image of children, children whose faces are "emptier than the faces of the dead," faces that contain no more feeling than that of "a snake or an insect" (Œ204). Indeed, this inverted image of children corresponds to the different mood of Childhoods End: in contrast to Clarke's other, op• timistic novels, a subtle pessimism pervades this science fiction classic. What is the source of this uncharacteristic sorrow? What shook the faith of this ardent proponent of space exploration, causing him to de• clare, "the stars are not for Man" (CE 136), even when he was chairman of the British Interplanetary Society? In assessing his reputation in the introduction to their seminal collection of essays on Clarke, Olander and Greenberg call him "a propagandist for space exploration [...] a brilliant "hard science fiction" extrapolator [...] a great mystic and modern myth-maker [...] a market-oriented, commercially motivated, and 'slick' fiction writer" (7). -
