Tower of strength versus leaning tower of Pisa ￼ ￼That there is an official report that Pisa tower is leaning. The tower on left is much older and stronger. Both are engineering marvels and few centuries old. But do we know reason why left tower stands erect while the Pisa tower year after year is leaning one to two mms per year. Google says Shifting soil had destabilized the tower's foundations. Over the next 800 years, it became clear the 55-metre tower wasn't just leaning but was actually falling at a rate of one to two millimeters per year. Today, the Leaning Tower of Pisa is more than five meters off perpendicular. As an Indian & as Tamilian we are proud of our ancestors who seemed to have advanced knowledge of various aspects of life and Engineering. While we keep marvelling this way, foreigners taken away knowledge contained in old manuscripts palm leaves written in Sanskrit and Brahmi and other languages and kept themselves busy researching these and announce to the world their findings as if they found it themselves. Example : superman is new Avatar of our lord Hanuman. Drones and aeroplanes are modified old Pushpa Vimanams. Modern missile technology - Dronacharya-Arjuna are forerunners of archery for similar effect. Bear with me for these and few more blah blah thoughts crossed my mind after seeing these images elsewhere.
