Dharmic researcher focused on the dating of the Mahabharata and for those who have some interest in the enigma of the concept of Yugas. The Yugas: - Rta, Treta, Dwapara and Kali, together believed to span total of 43,20,000 years emerged from the attempts to synchronise the lunar and solar calendars, both of which were used by the ancient Bharatiyas to recognise the flow of time and to seed crops as part of agricultural activities. Though I know Dr Achar in the domain of Mahabharata research, he was much more than that. He received his early education in India. He earned his MS and PhD degrees from the Pennsylvania State University. After his Post-Doctoral work at the Argonne National Laboratory, he taught at the Bucknell University, Pa before joining the Physics Department faculty in 1984.
