 The
cover picture is a photomontage of the large equatorial sundial at the
Jantar Mantar astronomical observatory situated in Jaipur. The stone
observatory was built by Maharaja Sawai Jai Singh, a keen astronomer
and mathematician, in the 18th century. The sundial is one of the
biggest and most accurate sundials in the world with an accuracy of a
few seconds. (See article on Standard Weights and Measures, page
40.)
