Kategoria BISAC: Science >> Physics - Gravity

The book introduces the general theory of relativity and includes applications to cosmology. The book contains a thorough introduction to tensor calculus and curved manifolds. After the necessary mathematical tools are introduced, we give a thorough presentation of the theory of relativity. Also, some advanced topics not previously covered by textbooks; e.g. Kaluza-Klein theory, Israel's formalism and branes. Anisotropic cosmological models are also included.

The book contains a large number of new exercises and examples, each with separate headings. The reader will get an updated...

Defying Gravity tells the astonishing story of how gravity pioneers transformed an ancient terror--the sensation of falling--into the modern thrill that powers extreme sports, monstrous amusement rides, and a youth culture obsessed with "getting air." It's a hair-raising tour, with nineteenth-century parachutists plummeting to their deaths before thousands, British lords tumbling from Alpine peaks, Hollywood stuntmen dropping from biplanes to freight trains, drunken carousers outrunning police to make the world's first bungee jump, and X Games athletes such as stunt bike rider Mat...

Since Einstein first described them nearly a century ago, gravitational waves have been the subject of more sustained controversy than perhaps any other phenomenon in physics. These as yet undetected fluctuations in the shape of space-time were first predicted by Einstein's general theory of relativity, but only now, at the dawn of the twenty-first century, are we on the brink of finally observing them.

Daniel Kennefick's landmark book takes readers through the theoretical controversies and thorny debates that raged around the subject of gravitational waves after the publication...

When a leaf falls on a windy day, it drifts and tumbles, tossed every which way on the breeze. This is chaos in action. In Fly Me to the Moon, Edward Belbruno shows how to harness the same principle for low-fuel space travel--or, as he puts it, "surfing the gravitational field."

Belbruno devised one of the most exciting concepts now being used in space flight, that of swinging through the cosmos on the subtle fluctuations of the planets' gravitational pulls. His idea was met with skepticism until 1991, when he used it to get a stray Japanese satellite back on course to...
