In this Very Short Introduction Timothy Clifton looks at the development of our understanding of gravity since the early observations of Kepler and Newtonian theory. He discusses Einstein's theory of gravity, which now supplants Newton's, showing how it allows us to understand why the frequency of light changes as it passes through a gravitational field, why GPS satellites need their clocks corrected as they orbit the Earth, and why the orbits of distant neutron stars speed up. Today, almost 100 years after Einstein published his theory of gravity, we have even detected the waves of gravitational radiation that he predicted. Clifton concludes by considering the testing and application of general relativity in astrophysics and cosmology, and looks at dark energy and efforts such as string theory to combine gravity with quantum mechanics.

Genre: Poetry

Gravity presents the first five books of poems from the sequence Gravity as a consequence of shape, started in 1982 and scheduled for completion in 2005. Gravity includes the books Brixton Fractals, Breadboard, Civic Crime, Dispossession & Cure, and Fizz. The sequence is an inversion of empirical demands. Each untitled poem has been relabelled with a jazz dance from a list of dances, from African Boog to Zip. The design of the overall work uses the model of a crushed cylinder, the process of a crumbling wall and a variety of contingent energies, interrupted narratives demonstrating crowd-outs, descriptions of shifts in focal consciousness, fleeting interruptions that damage continuities and expectations with named actors; Burglar, Badger, Fireman, Mathematician. These narratives are supported by decoherent syntax, moving positions that question strident notions of coherence and over-determined incoherences. This is a syntax that sometimes avoids and sometimes embraces tried stanza structures through the use of unreliable sentences and designed forms that exercise deliberate breaks from golden mean or idealised exactness. The poems rely on inconsistency leading to prepared and unexpected transformations that link or rhyme into following or previous poems. One preparation involved labelling a cylinder with stanza indications to provide sonority, bending the cylinder in upon itself and producing new damaged sonorities from the crushed indications. This transformed geometry energises the process of aesthetic productions in each reader’s involvement. One activity transforms words by sound, another by meaning and another by inversion or critique of its proposals. One unrealised proposal is to demonstrate truth. Another is to confirm a lack of reliance upon expectation. The subjects bridge biotechnology and quantum physics through a system of urban gardening and leaking streets. The proposals demand civility and are preposterous.

A young NASA doctor must combat a lethal microbe that is multiplying in the deadliest of environments -- space -- in this acclaimed blockbuster of medical suspense from Tess Gerritsen, bestselling author of Harvest, Life Support, and Bloodstream. Gravity Dr. Emma Watson has been training for the adventure of a lifetime: to study living beings in space. But her mission aboard the International Space Station turns into a nightmare beyond imagining when a culture of single-celled organisms begins to regenerate out of control -- and infects the space station crew with agonizing and deadly results. Emma struggles to contain the outbreak while back on Earth her estranged husband, Jack McCallum, works frantically with NASA to bring her home. But there will be no rescue. The contagion now threatens Earth's population, and the astronauts are stranded in orbit, quarantined aboard the station -- where they are dying one by one...

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.

Diplomarbeit aus dem Jahr 2009 im Fachbereich Ingenieurwissenschaften - Luft- und Raumfahrttechnik, Note: 1,8, Universitat der Bundeswehr Munchen, Neubiberg (Raumfahrttechnik), Sprache: Deutsch, Abstract: Bei den Vorbeiflugen am Mars und seinen Monden mit Mars-Express werden Schwerefeldmessungen durchgefuhrt, die zur Ermittlung der Masse von Phobos beitragen sollen. An der Bodenstation entsteht beim Empfanger thermisches Rauschen, das durch elektrische Schaltungen verursacht wird. Dieses unerwunschte Storsignal uberlagert sich mit dem ankommendem Signal, sodass die Information aus dem Rauschen gewonnen werden muss. Als Mass fur die Qualitat des Signals gilt das Signal-Rausch-Verhaltnis (SNR, Signal-to-Noise-Ratio). Es ist definiert als Verhaltnis zwischen der Signalleistung und der Rauschleistung. Je hoher der Wert des SNR ist, desto geringer ist der Einfluss des Rauschens auf die Messung. Zur Verbesserung des Signal- zu Rauschverhaltnis wurde zunachst auf die Filtertheorie zuruckgegriffen. In der Verarbeitung von analogen Signalen bestehen Filter aus passiven, sowie auch aus aktiven Bauteilen. Wenn die Bandbreitenbelegung des Eingangssignals begrenzt ist, reduzieren Filter das Rauschen ohne das Signal zu beeintrachtigen. In der Digitalverarbeitung ist es moglich denselben Effekt durch Berechnungen zu erreichen. Diese Technik ist bekannt als Numerical Filtering''. Die Verbesserung des Signal- zu Rauschverhaltnis mit verschiedenen numerischen Filterverfahren wurde untersucht und geeignete Filter wurden bestimmt. Dies fuhrte dazu, dass der Fehler bei der Massenbestimmung von Phobos um den Faktor 2-3 reduziert werden konnte. Um die Genauigkeit der Ergebnisse zu erhohen, werden in dieser Arbeit die Residuen weiter untersucht, um inharente Eigenschaften zu identifizieren, die eine noch wirkungsvollere Verarbeitung ermoglichen. Ziel der Analyse ist es, nutzliche Information, die eventuell noch im Residuum enthalten ist, aus dem Hintergrundrauschen zu gewinnen. Dies fuh
