Influence of Shivaji on Rabindranath

In the Baishakh issue of 'Bharati',  Sakharam Ganesh Deoki  published a few 'Historical Letters' (p. 62-71) on which Rabindranath commented as above. He had a deep regard for Shivaji.
He tried to identify synonyms in Bengali for words commonly used in science. In this respect he praised Mahalanabish's essay in Bengali on a science subject. He translated 'centripetal force' and 'centrifugal force' in Bengali as "kendranuga" and "kendratiga" which Upendrakishore termed as "kendrabhisarini" and "kendrapagamini".
