Since time immemorial, inventions have served as a demarcation of civilization’s advance. As humans have evolved, so, too, have the products of their ingenuity. From one of the first (fire) to several of the latest (the Internet, the fuel cell, genetic engineering), this book examines the inventions that have changed the world. The creation of revolutionary products or practices has no timetable. Great minds give birth to innovations as inspiration hits, necessity requires, or happenstance would have it. However, there have been a number of specifically fruitful periods of invention throughout history. The Renaissance, for instance, was a period of great intellectual exploration, an era of innovation in the arts, philosophy, medicine, engineering, and science. Inventions of the Renaissance include the printing press and movable type. It was also at this time that Leonardo da Vinci (1452–1519) drew the first plans for a flying machine, a precursor to planes and jets that would be devised and developed cen- turies later. The Industrial Revolution, which dates from the late 18th century through the early 19th century, was the great age of mechanization, characterized by the invention of machines for automating processes in manufacturing, mining, and agriculture. Automation made possible the creation of factories to mass-produce goods. Such goods could be sold at lower prices, which allowed ordinary people access to products they previously could not afford. Advances in transportation also allowed merchants to offer their goods and services over greater distances. Inventions within this timeframe include the power loom, the combine harvester, and the steam turbine, which powered the steamboats and train engines that delivered merchandise across countries and around the globe. 13 The Britannica Guide to Inventions 7 That Changed the Modern World 7 The Information Age, begun in the 20th century and bridging into the 21st, has changed the way people process information, conduct business, and communicate in general. It has had its share of important inventions as well. The computer, the cell phone, and the Internet have created the “Information Superhighway,” where information on anything is available instantaneously, and it is possible to be in contact with anyone at any time, anywhere in the world. An argument can be made that the Information Age could be extended to include inventions such as the telephone, the telegraph, the radio, and television—all of which made the dissemination of information more efficient and effective. This book details all of these inventions and more. What sets the included innovations apart and makes them noteworthy are the implications of their creation on cultures throughout the world. These are no flash-in-the- pan, fad items. Each profiled invention has had a potent and long-lasting impact on the way people live, work, and play—even their very survival. Energy is required to create products, heat homes, power equipment, and fuel a vast array of human activi- ties. The earliest form of energy that changed the world was fire—or, more accurately, the ability to control the use of fire.

Thanks also to my loving parents, who have always been there for me. The Early Years of the Acoustic Phonograph Its developmental origins and fall from favor 1877-1929 "Mary had a little lamb, its fleece was white as snov^. And everywhere that Mary went, the lamb was sure to go." With the recitation of a child's nursery rhyme, thirty-year- old Thomas Alva Edison ushered in a bright new age--the age of recorded sound. Edison's successful reproduction and recording of the human voice was the end result of countless hours of work on his part and represented the culmination of mankind's attempts, over thousands of years, to capture and reproduce the sounds and rhythms of his own vocal utterances as well as those of his environment. Although the industry that Edison spawned continues to this day, the phonograph is much changed, and little resembles the simple acoustical marvel that Edison created.

This fault zone has been proposed as a source of deep geothermal energy; to facilitate the design of a geothermal project in the town of Bishop Auckland further investigation of its geometry was necessary and led to the present study. We show using three-dimensional modelling of a dense local gravity survey, combined with structural inversion, that this fault has a ramp-flat-ramp geometry, ~250 m of latest Carboniferous / Early Permian downthrow having occurred on a fault surface that is not a planar updip continuation of that which had accommodated the many kilometres of Dinantian extension. The gravity survey also reveals relatively low-density sediments in the hanging-wall of the Dinantian fault, interpreted as porous alluvial fan deposits, indicating that a favourable geothermal target indeed exists in the area.

Governor Mike Beebe and Irish Consul General Martin Rouine have been invited to attend the ceremony in Calvary Cemetery at 2 p.m. March 14. King was buried there after he died in May 1938 while being treated for pneumonia at the Army & Navy General Hospital. The March 14 ceremony is being coordinated by the Hot Springs Convention and Visitors Bureau with the assistance of the Thadeus H. Caraway Post 2278 of the Veterans of Foreign Wars and Post Commander Ralph Faresc. The VFW is coordinating the military portion of the event and several other local groups have asked to be involved with the ceremony. Calvary Cemetery, the local Catholic cemetery is located at the intersection of Greenwood Avenue and Third Street. The shortest route is to take Central Avenue to Greenwood and turn west. Details about King’s life and the circumstances surrounding his two Medals of Honor were extremely sketchy until Elizabeth Robbins, executive director of the Garland County Historical Society, began an intensive search for more information.

(U.Qld.) DEPARTMENT OF ACCOUNTING, FINANCE & ECONOMICS GRIFFITH BUSINESS SCHOOL GRIFFITH UNIVERSITY Submitted in fulfilment of the requirements of the degree of Doctor of Philosophy July 2006 ii ABSTRACT This thesis describes the rail gauge decision-making processes of the Australian colonies in the period 1850 – 1901. Federation in 1901 delivered a national system of railways to Australia but not a national railway system. Thus the so-called “standard” gauge of 4ft. 8½in. had not become the standard in Australia at Federation in 1901, and has still not. It was found that previous studies did not examine cause and effect in the making of rail gauge choices. This study has done so, and found that rail gauge choice decisions in the period 1850 to 1901 were not merely one-off events. Rather, those choices were part of a search over fifty years by government representatives seeking colonial identity/autonomy and/or platforms for election/re-election. Consistent with this interpretation of the history of rail gauge choice in the Australian colonies, no case was found where rail gauge choice was a function of the disciplined search for the best value-for-money option.

  • Kampen Om Kvinnan
    Ulrika Nilsson Kampen om Kvinnan Professionalisering och konstruktioner av kön i svensk gynekologi 1860–1925 Doktorsavhandling för filosofie doktorsexamen i idé- och lärdomshistoria framlagd vid Uppsala universitet 2003. ABSTRACT Nilsson Ulrika, 2003: Kampen om Kvinnan: Professionaliseringsprocesser och konstruktioner av kön i svensk gynekologi 1860-1925 (The Politics of Woman: Pro- fessionalisation Processes and Constructions of Gender in Swedish Gynaecology, 1860-1925). Written in Swedish with an English summary. Institutionen för idé- och lärdomshistoria, Uppsala universitet, Skrifter 31. 458 pp. Uppsala. ISBN 91- 506-1721-4. This thesis investigates how gynaecology was established as a medical speciality in Sweden in the 1860s and onwards. Gender, power, professionalisation and the pro- duction of scientific knowledge are central themes. While previous research has shown that gynaecology as a discipline depends upon notions of Woman as radi- cally different from Man, I show how this was manifested within Swedish gynae- cology, an initially all male environment. Of special interest is institutionalisation, early career-paths and the development of therapy methods and theory. I argue that gynaecology reproduced and contributed to notions of sex-difference and a gender complementary way of thinking. While gynaecology was formed as a surgically interventionist speciality with strong manly connotations, an education reform aiming at opening higher education to women was simultaneously discussed and eventually carried out during the 1860s

  • THE STUDY of SATURN's RINGS 1 Thesis Presented for the Degree Of
    1 THE STUDY OF SATURN'S RINGS 1610-1675, Thesis presented for the Degree of Doctor of Philosophy in the Field of History of Science by Albert Van Haden Department of History of Science and Technology Imperial College of Science and Teohnology University of London May, 1970 2 ABSTRACT Shortly after the publication of his Starry Messenger, Galileo observed the planet Saturn for the first time through a telescope. To his surprise he discovered that the planet does.not exhibit a single disc, as all other planets do, but rather a central disc flanked by two smaller ones. In the following years, Galileo found that Sa- turn sometimes also appears without these lateral discs, and at other times with handle-like appendages istead of round discs. These ap- pearances posed a great problem to scientists, and this problem was not solved until 1656, while the solution was not fully accepted until about 1670. This thesis traces the problem of Saturn, from its initial form- ulation, through the period of gathering information, to the final stage in which theories were proposed, ending with the acceptance of one of these theories: the ring-theory of Christiaan Huygens. Although the improvement of the telescope had great bearing on the problem of Saturn, and is dealt with to some extent, many other factors were in- volved in the solution of the problem. It was as much a perceptual problem as a technical problem of telescopes, and the mental processes that led Huygens to its solution were symptomatic of the state of science in the 1650's and would have been out of place and perhaps impossible before Descartes.

    Poliomyelitis and the Neurologists: The View from England, 1896-1966 ANNE HARDY The American vs. the European Experience In 1907, following one of the earliest poliomyelitis outbreaks in New York City, the New York Neurological Society set up a poliomyelitis committee with a view to studying and illuminating the behavior of this newly epi- demic disease.' The neurologists7 interest in polio was of long standing, dating from the orthopedic surgeon Jacob von Heine's conclusion, in 1860, that the symptoms of infant paralysis pointed to "an affection of the central nervous system, namely the spinal cord."* Ten years later, Heine7s deduction had been confirmed by the researches ofJean-Martin Charcot (1825-93), who demonstrated the destruction of the grey matter of the anterior horns of the spinal cord (within which the motor impulses arise and are transmitted) in cases of infant paralysk3 This demonstration of the pathology of the disease placed it firmly within the concerns of neurol- ogy, where it remained until polio arrived as a major epidemic problem. In America, according to John R. Paul, the New York Neurological Society's committee marked "almost the last time that neurologists as a professional body were to assume a position of dominance with respect This article was written in memory of Elizabeth Mary Margaret Hardy (1922-52).
