Biografi af Beatrice Shilling, som i 1929 blev ingeniør med afgangseksamen fra Manchester University, lidt usædvanligt som kvinde. Shilling var fokuseret på det tekniske område og ombyggede bl.a. en Norton motorcykel således at den kunne nå op på en hastighed af 105 miles per hour. I 1930 blev hun ansat ved Royal aircraft Establishment i Farnborough, hvor hun blev specialist i kaburatorer. Under den 2. verdenskrig løste hun problemet vedrørende tab af motorkraft når fly dykkede (negativ g). Senere arbejde hun med raketbrændstop og ramjets.

A history of gravity, and a study of its importance and relevance to our lives, as well as its influence on other areas of science. Physicists will tell you that four forces control the universe. Of these, gravity may the most obvious, but it is also the most mysterious. Newton managed to predict the force of gravity but couldn't explain how it worked at a distance. Einstein picked up on the simple premise that gravity and acceleration are interchangeable to devise his mind-bending general relativity, showing how matter warps space and time. Not only did this explain how gravity worked – and how apparently simple gravitation has four separate components – but it predicted everything from black holes to gravity's effect on time. Whether it's the reality of anti-gravity or the unexpected discovery that a ball and a laser beam drop at the same rate, gravity is the force that fascinates.

A distinguished physicist and teacher takes a reader-friendly look at three scientists whose work unlocked many of the mysteries behind the laws of physics: Galileo, Newton, and Einstein.

Gravity - Galileo to Einstein and Back starts with a revision of the fundamentals of the theory of dynamics and gravitation. The primary object is to present a relativistic theory of gravitation, which is an extension of the Special Theory of Relativity. The new approach to gravitomagnetics reproduces results which are identical, for the precession of the perihelion of Mercury and for the deflection of light grazing the Sun, to those given by the general theory of relativity. Both of these were hailed as justifications of the general theory. When the new theory is applied to the precession of a gyroscope in space, there is a small difference from the value quoted to that given for the NASA/Stanford Gravity Probe B experiment, which has just been completed. The results are due in Spring 2007. In order to explain the new approach, it is necessary to re-examine Newtonian dynamics and special relativity. Certain aspects are better seen if force is treated as a defined quantity rather than a primary one. This idea is not new; it was the view of d'Alembert and especially H. R. Hertz. One result is that the principle of equivalence, in its weak form, does not arise, yet this is stated to be one of the foundations of general relativity. Curved space time may be regarded as just another invention to replace the invention of force. Neither are needed but are very useful concepts, as is money to commerce. Newtonian gravity gives rise to a relative acceleration which is related to the relative position between two bodies, in the new gravitomagnetic theory relative acceleration depends also on relative velocity. This removes the need for an inertial frame of reference however the frames must be non-rotating. This is defined by postulating that light, in the absence of matter, travels in straight lines as well as at a constant speed. What follows is reasonably simple mathematics; certainly simpler than that of curved space time.

This book deals with different aspects of gravity that has proved its effectiveness throughout the world, hence their solicitation in recent years. Fundamental theories, applications, and tools have been presented, emphasizing the implementation of the gravity technique. Different research themes for diverse areas in the world are detailed here, highlighting new methods of studies that could be helpful for sophisticated and modern development over the next few years. Four main sections are presented: Gravity Interpretation Tools in Geoscience, Gravity in Geoscience Applications, Gravity in Industrial Technology, and Quantum Gravity. Theoretical and acquisition tools and adapted processing methods have been designed to take into account the initial data, and modeling results thus converge toward a better solution. This book, which makes a worthwhile contribution to the topic gravity, is specifically addressed to specialists, researchers, and industry professionals who shall find its content extremely useful for a better comprehension of the geological, spatial, and industrial aspects of gravity.

This book invites the reader to understand our Universe, not just marvel at it. From the clock-like motions of the planets to the catastrophic collapse of a star into a black hole, gravity controls the Universe. Gravity is central to modern physics, helping to answer the deepest questions about the nature of time, the origin of the Universe and the unification of the forces of nature. Linking key experiments and observations through careful physical reasoning, the author builds the reader's insight step-by-step from simple but profound facts about gravity on Earth to the frontiers of research. Topics covered include the nature of stars and galaxies, the mysteries of dark matter and dark energy, black holes, gravitational waves, inflation and the Big Bang. Suitable for general readers and for undergraduate courses, the treatment uses only high-school level mathematics, supplemented by optional computer programs, to explain the laws of physics governing gravity.

th The 29 International Conference was held as the first one of the millennium at its Fort Lauderdale venue. These conferences began, with High Energy Physics being the main topic, by introducing gradually cosmology into its programs. These proceedings of the 2000 conference reflect the variety of topics and ideas discussed. Our future conferences will be designed somewhat akin to the early Coral Gables Conferences where we shall seek some convergence of ideas. For this reason various committees have been formed from among the participating physicists. The committees and their memberships are listed in these proceedings. We further decided for the first time to include some graduate student participants in our future meetings for which also a committee has already been established. The topics will demonstrate a more activist structure of the Coral Gables Conferences, for example the duality of the gravitational forces and expansion of the universe will be discussed from this point of view since it conveys a convergence to the ideas of quintessence versus the ordinary theory, which are considered as the cause of the expansion of the universe. We further wish to announce that the future conferences will assume a collective organization where several committees as listed in these proceedings will have their input into the conference. We have now introduced new topics and ideas, which referred especially to the attractive and repulsive nature of the gravitational force. These proceedings of the conference contain a variety of topics and ideas.

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 STORY: Wounded in the war in Iraq, a farmer's boy turned soldier returns home with injuries that have extraordinary consequences for his fiancée and his family.

The Euclidean approach to Quantum Gravity was initiated almost 15 years ago in an attempt to understand the difficulties raised by the spacetime singularities of classical general relativity which arise in the gravitational collapse of stars to form black holes and the entire universe in the Big Bang. An important motivation was to develop an approach capable of dealing with the nonlinear, non-perturbative aspects of quantum gravity due to topologically non-trivial spacetimes. There are important links with a Riemannian geometry. Since its inception the theory has been applied to a number of important physical problems including the thermodynamic properties of black holes, quantum cosmology and the problem of the cosmological constant. It is currently at the centre of a great deal of interest.This is a collection of survey lectures and reprints of some important lectures on the Euclidean approach to quantum gravity in which one expresses the Feynman path integral as a sum over Riemannian metrics. As well as papers on the basic formalism there are sections on Black Holes, Quantum Cosmology, Wormholes and Gravitational Instantons.
