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.

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.

The Story of the Earth presents the complex history of the Earth from its formation through to the emergence of man and his influence on the planet. Peter Cattermole and Patrick Moore trace the evolution of Earth from its beginnings in the primeval Solar Nebula, through its bombardment by cosmic particles, continental drifting and the formation of mountains and oceans, and end with a study of the last Ice Age and the rise of man. While the approach is roughly chronological, time is spent in explaining some of the methods that geologists, physicists, chemists and biologists use to discover what processes have contributed to the internal make-up and external appearance of our unique planet. Accounts are included of the dramatic events that are still changing the face of the Earth: volcanoes and photographs - several taken from orbiting satelites - help to elucidate the story.

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.

This best-selling historical geology text provides geologists with an excellent balance of basic geology and paleontology. The ninth edition presents rich, authoritative coverage of the history of the Earth, offering the most comprehensive history in the discipline today. It maintains its strong approach to stratigraphy and paleontology that other texts have lost. The text's paleogeographic maps are excellent in detail and are a vital component in understanding the earth's history. Stunning artwork brings the ancient world to life. Geology of National Parks boxes encourage them to visit these parks to appreciate their geological significance. Geologists will also appreciate the questions about past geologic events and the processes used in finding answers.

We're very happy you shared your theory, and good luck for your book! Best of luck!” Oana Sandu, Hubble Community Coordinator at the European Space Agency (ESA), October 14, 2019.

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 present volume is the result of activities within the scientific programme "Response of the Earth System to Impact Processes" (IMP ACT) of the European Science Foundation (ESF). The ESF is an association of 67 national member organisations devoted to scientific research in 24 European countries. The IMPACT programme is aimed at understanding meteorite impact processes and their effects on the Earth System. Launched in 1998 for a duration of 5 years, the programme is now supported by 15 ESF membership countries. The programme of meteorite impact research and operates through deals with all aspects workshops, exchange programs, and short courses. The 4th IMPACT programme workshop "Meteorite Impacts in Precambrian Shields" took place on May 24-28, 2000, in Lappajarvi, western Finland. A total of 84 scientists from 19 countries from Europe, North America, and Africa participated in the workshop. During the workshop, 43 oral, 31 poster, and several video presentations were made. An exhibition of impactite rocks from Finnish craters and two excursions were organised. The excursion to impact melt rock outcrops of the Lappajarvi structure took place during the workshop. The Karikkoselka and Saaksjarvi impact structures in south-central Finland were visited during the post-meeting excursion.
