Jantar Mantar Delhi
The name Jantar Mantar has been derived from Sanskrit language. Yantra (Jantar) means instruments and mantra means formulae. Hence in the parlance of scientific community, Jantar Mantar is an observatory to accomplish scientic purposes at the time when high performing, result oriented modern day scientific instruments were nowhere in sight.
It was constructed in 1724 by the Maharaja of Jaipur, Jai Singh who fostered the idea of building a fully functional and well equipped structure that can obviate the need of inaccurate astronomical instruments present at that time. Hence Jantar Mantar came into existence. The whole structure is made of stone and marble where every contour has significance of its own. The Samrat Yantra, the Ram Yantra, the Jayaprakash and the Mishra yantra, are few of the elite 13 instrument that were used to study movements and behavior of heavenly bodies namely, the sun, the moon and stars.
Once a harbinger of scientific era and an epitome of inventiveness in field of astronomy, Jantar Mantar has lost its sheen as an instrument of measurement; the reason being construction of building around the structure which hinders the process of accurate observations. Nevertheless, a scientific trailblazer, Jantar Mantar, is now serving as "ground zero" for people with a cause who likes to see India veering and thriving towards a better and brighter future.
