My next stop in Jaipurwas the Jantar Mantar. It is one place where you can see and be surprised about the advancement of ancient Indians in the field of astronomy. Instead of building instruments, the ancient Indians built various architectural structures to track the time of the day, solar and lunar position. These structures were used by the kings in various decision-making.
It is one place where I felt that there is much more to learn from our past. We have highly advanced technology now to measure time, predict solar and lunar (and other planets) position precisely. But the ancient Indians lacked them and yet they were able to predict much of the celestial information precisely
