Jantar Mantar of Jaipur is an architectural master piece; it is the ever built 'Astra- Physical Constants' on stones structures. Large geometrical devices are set accordance with sun to predict time, seasons, periods and eclipses. It's unique in its architecture, since there is no pattern to describe its architectural works. It is totally built with geometry related to physics. There are many instruments placed in the observatory and many scientists are still behind them to know the purpose of those instruments. From outside view it will be more or like a children's play park. But from the inside it's an enigma to understand them until guide explains you or you read the content shown on its display. It is a series of small and large stone structures which are unique and defines some sort of measurements related to astronomy.
Jantar Mantar of Jaipur is of vast historical significance in the world. It is listed with UNESCO and in World Heritage sites. Indians are well known for their universal studies from the Vedic time itself. There are accurate predictions made by them are in records. Maharaja Jai Singh to learnt few mathematics and started calculating various natural events from his child hood. This armature interest result him to build the observatory for the knowledge of common man to look it as a time machine a calendar and a forecast of seasons. From its origin to now the accuracy of time is less than a plus or minus 2 minutes. A few scientists do belief that it was a place for alien interaction and a time machine to enter in to space may be secretly experimented there. Still scientists are not able to describe the purpose of many physical instruments in that observatory, since the written records were lost with time. It is a master piece for students, scientist, historian and artisans.
Jantar Mantar of Jaipur is a tourist spot for its enigma. If a person look at his watch and looks on the 'samrat yantra' a time machine were suns shade show the exact time. Here one will get mad to see such precisions. Not only time, but the entire celestial time can be seen in the day as well as in the night. All these structures are built with sand stones and marbles. The geometrical instruments are built in bronze. For all those armature astronomers it is advisable to come on any of the periodic natural events on earth like "All four equinox days, celestial positions, full moon days, climatic predictions, north pole stars direction, eclipse day, summer and winter solicit days" here one can witness the accuracy of this architectural mystery. All are welcome here, and is open to public on normal days. In short it is the only pre telescopic observatory in the world. And one should not miss to see its universal enigma in Jantar Mantar located near Jaipur.
