Realms of time and space

REALM,S OF TIME AND SPACE
The theory of relativity has been called the greatest triumph ever achieved by the disciplined imagination. When it was first proposed, in 1905, it shattered the traditional concepts of space-time, energy, and matter. Twelve years later its extended version challenged Newton's theory of gravity, replacing it with the concept of curved space. Its mathematical expressions disclosed some the nature's most intimate secrets. One of its equations became the backbone of the atomic age.
Physicists have a special respect for relativity because, unlike other theories that fade away with time, relativity has become more relevant today than in its early years. Black holes, expanding universe, the big-bang theory, all borrow heavily from relativity.
Relativity's chief architect was Albert Einstein, a brilliant scientist, a concerned citizen, and a warm human being. He was good for nothing student who detested regimented wrote learning experiences of his youth. He sharpe...
