The Story of Time

A world without time! It could be a chaotic place to live in. Man has been trying ever to reckon time. He watched nature's clocks-the rising and setting of the sun, changing of the seasons, growth of a body and mutation in all creation. From shadow sticks to sundials to waterclocks to the present day clocks that are acurate to one millionth of a second and further-it is indeed the story of time. A most significant idea that has resulted through untiring research is the concept of time-space-continuum as an indivisible unity. Time remains a scientific mystry!
