Parameswaran, the nuclear scientist who left Bhabha Atomic Research Centre to become a leading Marxist theorist and people's science activist, died in Thrissur, Kerala, on Tuesday. He was 92. Parameswaran was a key figure in Kerala Sastra Sahithya Parishad (KSSP) and helped found the All India People's Science Network and Bharat Gyan Vigyan Samiti, which ran mass literacy campaigns. His 2004 book 'Fourth World' argued for decentralised democracy and a break from consumerism. It provoked fierce internal debate and led to his expulsion from the CPI(M) on charges of indiscipline. Parameswaran authored many popular science books in Malayalam and English on topics from atomic energy to ecology. ## Coverage - thehindu.com Tags: BARC, CPI(M), Fourth World, Kerala Sastra Sahithya Parishad, M.P.
