A place worth remembering
Jantar Mantar: instruments for more accurate measurements
Delhi Tourism links the observatory’s larger instruments to Jai Singh’s pursuit of correct readings; the equipment then in use had proved too small for that task.[1]
The Bahá’í House of Worship: nine pools around the building
The temple’s architecture account gives the surrounding pools two roles: they echo lotus leaves and also help ventilate the building.[2]
Jantar Mantar today and Jai Singh’s other observatories
Delhi Tourism glosses the name as yantra, instruments, and mantra, formulae. It says Maharaja Jai Singh of Jaipur later built observatories at Ujjain, Varanasi and Mathura too, and adds that tall buildings around the Delhi site mean precise readings are no longer possible there.[1]
