In other words, using purely mathematical methods of the General

Theory of Relativity, Zelmanov showed that any observer forms his world-picture from a comparison between his observation results and some standards he has in his laboratory--the standards of different objects and their physical properties.

This biography of Einstein begins with an engaging account of his childhood and early adulthood, and then focuses on the "annus mirabilis" or "miracle year" of 1905, when Einstein created his most important work, "The

Theory of Relativity.

In publications in 1922 and 1924 the Russian mathematician Alexander Friedmann used the formulae of the General

Theory of Relativity to prove that the universe was dynamic: either it expanded or it shrunk.

Einstein's

theory of relativity isn't fosilized, rather it is under active development at the moment.

whose General

Theory of Relativity looms large in this book, spent the last decades of his life trying to find a unified theory of physics, one that would unite everything we know about matter and energy, from the smallest particles to the cosmos on its grandest scale.

Both of these two models are mathematical extensions of Einstein's General

Theory of Relativity.

The scientist, whose

theory of relativity revolutionized 20th-century physics, got twice as many votes as second-place JOHANN GUTENBERG, the inventor of the movable-type printing press.

One of the first books on electromagnetics that contains the general

theory of relativity, which is needed in the design of mobile systems such as global positioning system (GPS)

Washington, April 26 ( ANI ): An exotic pair of binary stars nearly 7,000 light-years from Earth have provided evidence that Albert Einstein's

theory of relativity is still right, even in the most extreme conditions tested yet.

Einstein, best known for the

theory of relativity, was a member of staff at the Institute for Advanced Study at Princeton University.

Measurements of spin provide a critical new test of Einstein's general

theory of relativity, which predicts that spinning black holes drag space-time along with them.

Chapter topics feature the notion of timetables as elementary representations of space-time, the role of reflections, Einstein's

theory of relativity, relativity theory and paradoxes, elementary metric properties of the Minkowski geometry compared to Euclidean analogs, and the Cayley-Klein geometries.

NEWHALL - Imagine what might have happened if Pablo Picasso had run into Albert Einstein in 1904 in a Paris bar, one year before Einstein published his

theory of relativity and three years before Picasso painted one of his most famous works, ``Les Demoiselles d'Avignon.

In that one year, the then 26-year-old Einstein worked in the Swiss Patent Office; established beyond a doubt the existence and sizes of molecules; explained light as both particles and waves; and created the Special

Theory of Relativity, part of which linked matter and energy in the now-famous equation E=mc(2).

Professor John Brown, tenth Astronomer Royal for Scotland, believes only quantum mechanics and the

theory of relativity, which distorts space time boundary, can explain Father Christmas delivering gifts to all the good girls and boys in just one night.
