Jantar Mantar - Ram Yantra
Jantar Mantar, the 18th century astronomical observatories in Jaipur built by Raja Jai Singh II, the mathematician and astronomer king. These observatories havemasonry instruments to measure time, observing constellations and orbits of astronomic objects. The Jaipur observatory is a UNESCO World Heritage site. Although there are many instruments, and each one has its own astronomical significance, and explaining them in Hindi for students who have no background in Astronomy is a very challenging task. Therefore, there are two videos on one important instrument, called Raam yantra. Part I provides the introduction and part II provides the technical information on how this instrument is used for measurement of local time.
