From the anthracite mines of Pennsylvania at Carbondale to the Hudson River in New York near Kingston, the Delaware & Hudson Canal Company and the Gravity Railroad transformed long tracks of wilderness into thriving economic areas. Conceived as an inexpensive way to transport anthracite coal, the canal began hauling loads in 1828 to the Hudson River, where barges to New York City took over. A leader in the technologies of the time, the canal company used the first telegraph system in America, and when Delaware & Hudson engineer Horatio Allen ran the locomotive Stourbridge Lion in Honesdale, he became the first to run a commercial steam locomotive on tracks in the Western Hemisphere. The Delaware & Hudson Canal was privately funded, and when stock was offered for sale in 1825, it soon became the first American company capitalized at $1 million. The Delaware & Hudson Canal and the Gravity Railroad uses fascinating vintage photographs to tell an amazing piece of American history. It shows the mules, the canal boats, the locomotives, and the men who ran this technological wonder, boasting one hundred eight locks over one hundred eight miles, plus four suspension aqueducts built by John A. Roebling of Brooklyn Bridge fame. The Gravity Railroad is shown as well, hauling coal from Carbondale to Honesdale over the Moosic Mountains, a rise of more than one thousand feet. The Delaware & Hudson Canal and the Gravity Railroad tells the story of an American industrial masterpiece.
When Harry Ehlers demonstrated his gravity machine at an American Physics conference he thought there would be some interest from the press and society at large. He wasnt prepared for the overwhelming manner in which he was thrust into the spotlight as the man who was changing history. His ideas would impact on just about every structure of society: transport, town planning, global mobility, altered power balances and availability of space flight. Harry patented the theory, but discovers there are many people who believe they are entitled to proceeds. Potential manufacturers clamour for information, and a semi-secret international organisation wants to acquire the patent rights. Harry refuses to sell, and then hears that an Armenian scientist claimed prior submission of the gravity machine ideas. By nature Harry is a loner, and he battles to come to terms with the different pressures on his life. At a personal level he discovers his new girlfriend has been raped, and then she rebuffs him when he is set up with a starlet. He finds out just how high the stakes are when he is confronted by an assassin on a dive boat
The lAG International Symposium on Gravity, Geoid, and Space Missions 2004 (GGSM2004) was lield in the beautiful city of Porto, Portugal, from 30 August to 3 September 2004. This symposium encompassed the themes of Commission 2 (Gravity Field) of the newly structured lAG, as well as interdisciplinary topics related to geoid and gravity modeling, with special attention given to the current and planned gravi- dedicated satellite missions. The symposium also followed in the tradition of mid-term meetings that were held between the quadrennial joint meetings of the International Geoid and Gravity Commissions. The previous mid-term meetings were the International Symposia on Gravity, Geoid, and Marine Geodesy (Tokyo, 1996), and Gravity, Geoid, and Geodynamics (Banff, 2000). GGSM2004 aimed to bring together scientists from different areas in the geosciences, working with gravity and geoid related problems, both from the theoretical and practical points of view. Topics of interest included the integration of heterogeneous data and contributions from satellite and airborne techniques to the study of the spatial and temporal variations of the gravity field. In addition to the special focus on the CHAMP, GRACE, and GOCE satellite missions, attention was also directed toward projects addressing topographic and ice field mapping using SAR, LIDAR, and laser altimetry, as well as missions and studies related to planetary geodesy.
In the tradition of The Anti-Gravity Handbook and the Time-Travel Handbook comes this all-new compilation of material on anti-gravity, free energy, flying saucers and Tesla technology. With plenty of technical drawings and explanations, this suppressed technology will change the world in ways we can only dream of. Chapters on anti-gravity mercury gyros, the motionless electromagnet generator patent, the Tesla pyramid engine, anti-gravity patents, rare photos of the machines in flight, and tons more. The book that finally blows the lid on suppressed technology and anti-gravity! Heavily illustrated.
The author of this history of mankind’s increasingly successful attempts to understand, to measure and to map the Earth’s gravity field (commonly known as ‘little g’ or just ‘g’) has been following in the footsteps of the pioneers, intermittently and with a variety of objectives, for more than fifty years. It is a story that begins with Galileo’s early experiments with pendulums and falling bodies, progresses through the conflicts between Hooke and Newton and culminates in the measurements that are now being made from aircraft and satellites. The spectacular increases in accuracy that have been achieved during this period provide the context, but the main focus is on the people, many of whom were notable eccentrics. Also covered are the reasons WHY these people thought their measurements would be useful, with emphasis in the later chapters on the place of ‘g’ in today’s applied geology, and on the ways in which it is providing new and spectacular visions of our planet. It is also, in part, a personal memoir that explores the parallels between the way fieldwork is being done now and the difficulties that accompanied its execution in the past. Selected topics in the mathematics of ‘g’ are discussed in a series of short Codas.
This near-future (2060s) thriller set in Alaska and Seattle, from the Philip K. Dick Award–winning author of Watermind, will resonate with anyone who has ever lost someone they loved, and fought to win them back.
These Proceedings include the written version of papers presented at the IAG International Symposium on "Gravity, Geoid and Earth Observation 2008". The Symposium was held in Chania, Crete, Greece, 23-27 June 2008 and organized by the Laboratory of Geodesy and Geomatics Engineering, Technical University of Crete, Greece. The meeting was arranged by the International Association of Geodesy and in particular by the IAG Commission 2: Gravity Field. The symposium aimed at bringing together geodesists and geophysicists working in the general areas of gravity, geoid, geodynamics and Earth observation. Besides covering the traditional research areas, special attention was paid to the use of geodetic methods for: Earth observation, environmental monitoring, Global Geodetic Observing System (GGOS), Earth Gravity Models (e.g., EGM08), geodynamics studies, dedicated gravity satellite missions (i.e., GOCE), airborne gravity surveys, Geodesy and geodynamics in polar regions, and the integration of geodetic and geophysical information.
