M.P. Parameswaran, a nuclear scientist who walked away from a prestigious career at the Bhabha Atomic Research Centre to take science to ordinary people, passed away at his residence in Thrissur, Kerala, on August 11, 2026. He was 91. A founding leader of the Kerala Sasthra Sahithya Parishad (KSSP) and the All India People’s Science Network (AIPSN), Parameswaran spent nearly five decades bridging the gap between science and society, championing environmental causes, and provoking one of the most intense ideological debates within India’s Left politics through his controversial “Fourth World” theory.
Early Life and Education
Parameswaran was born on January 18, 1935, in the village of Kiralur in Thrissur district, then part of the princely state of Cochin. He received his early education at Thrissur Namboothiri Vidyalayamu and later at CMS High School and St Thomas College. In 1956, he earned a Bachelor’s degree in Electrical Engineering from the College of Engineering, Trivandrum.
After graduating, Parameswaran travelled to the Soviet Union and obtained a PhD in Nuclear Engineering from the Moscow Power Engineering Institute in 1965. This qualification brought him back to India, where he joined the Bhabha Atomic Research Centre (BARC) in Mumbai in 1957. BARC, established in 1954 by Homi J. Bhabha, is India’s premier nuclear research facility and the backbone of the country’s nuclear programme. Parameswaran worked there for nearly two decades, becoming part of the scientific establishment that was building the foundations of India’s nuclear capabilities during a critical period of the Cold War and India’s early nuclear ambitions.
Between 1969 and 1973, he served as the Assistant Director of the State Institute of Languages in Kerala, on deputation from BARC. During this period, he played a crucial role in designing the layout for the Malayalam keyboard for typewriters, which was later adopted in the inscript layout for computers. This contribution ensured that the Malayalam script could transition smoothly from the age of typewriters to the digital era, making it one of the earliest instances of technology localisation in India.
From Nuclear Science to People’s Science
In 1975, Parameswaran made a decision that would define the rest of his life. He left BARC, one of India’s most prestigious scientific institutions, and chose to devote himself full-time to the Kerala Sasthra Sahithya Parishad (KSSP). The decision was not driven by disillusionment with science but by a deeper conviction that science could not remain locked inside laboratories, universities and governments. It had to become a language that ordinary people could understand and use.
This was a radical proposition in the 1970s. India’s scientific establishment was largely top-down, with knowledge flowing from institutions to the public through formal education channels. Parameswaran believed that knowledge became democratic only when it could be understood by people in their own language. He wrote extensively in Malayalam, making difficult subjects accessible without stripping them of their complexity. Nuclear science, astronomy, mathematics, ecology, economics and technology entered the pages of books and pamphlets that travelled far beyond the educated middle class. He authored around 100 books in Malayalam and English over his lifetime, many of which won national and state awards.
The Kerala Sasthra Sahithya Parishad (KSSP)
The KSSP, whose name translates to the Kerala Forum for Science Literature, was founded on September 10, 1962, at Devagiri College in Kozhikode. It began as a small forum of about 40 science writers with the modest objective of publishing science literature in Malayalam. By 1968, it had made contact with scientists from Kerala working across India and had become a well-defined organisation focused on the mass dissemination of science.
In 1972, the KSSP adopted the motto “Science for Social Revolution” and transformed itself from a writers’ forum into a People’s Science Movement. Under Parameswaran’s leadership, the organisation grew into a massive movement with a membership exceeding 50,000 people distributed across approximately 1,200 units throughout Kerala. The KSSP used innovative communication strategies, including the Kala Jatha (a travelling cultural troupe using art, music, theatre and dance to bring scientific ideas to rural villages), to reach people who had never been part of formal science education.
One of KSSP’s most widely known innovations was the smokeless stove, which revolutionised cooking in rural Kerala by reducing dependence on firewood. The organisation also published three periodicals and hundreds of books and booklets, making it one of the most prolific science publishing operations in any Indian language.
Taking Science to the Streets: Bharat Jan Vigyan Jatha and AIPSN
After establishing KSSP as a successful model in Kerala, Parameswaran set his sights on replicating this at a national level. In 1987, he served as the Convener of the National Organising Committee of the Bharat Jan Vigyan Jatha (BJVJ), one of the largest science communication experiments ever conducted in India. The BJVJ was a massive nationwide campaign involving 26 people’s science groups that used cultural forms, street plays, slide shows, public meetings and mobile science exhibitions to bring scientific ideas to villages and towns across the country. It was supported by the National Council for Science and Technology Communication (NCSTC) under the Department of Science and Technology.
The BJVJ was launched in the wake of the 1984 Bhopal gas tragedy, one of the world’s worst industrial disasters, which had exposed the catastrophic consequences of technology without public accountability. Following the tragedy, Parameswaran organised a remarkable Science Train from Thiruvananthapuram to Bhopal, with nearly 1,000 KSSP activists travelling across the country to spread scientific awareness and explain the criminal dimensions of the disaster to ordinary people.
In 1988, this national coordination culminated in the formation of the All India People’s Science Network (AIPSN) at the first All India People’s Science Congress in Kannur, Kerala. The AIPSN brought together over 40 people’s science organisations spread across 25 states, creating a national platform for science communication and social activism. Parameswaran served as its secretary and later as its president. The AIPSN pioneered adult literacy efforts at the national level in 1990 through the Bharat Gyan Vigyan Samiti (BGVS), which partnered with the government’s National Literacy Mission to spearhead Total Literacy Campaigns across districts nationwide. Through these campaigns, the network reached 60,000 villages across India, one of the most expansive grassroots mobilisations in post-independence India.
Championing Environmental Causes
Parameswaran’s commitment to questioning development for the sake of development found its most visible expression in environmental movements. He understood that ecology was inseparable from economics, politics and social justice, and that a forest could not be defended permanently without asking why people were dependent on its resources, who controlled land and technology, and who benefited from large projects while bearing their costs.
The Silent Valley Movement
The Silent Valley Movement stands as one of the most important chapters in India’s environmental history, and Parameswaran was one of its key leaders. Silent Valley, a 90-square-kilometre stretch of pristine tropical evergreen rainforest in the Palakkad district of Kerala, is home to extraordinary biodiversity, including the endangered lion-tailed macaque. Scientists believe the forest has a continuous record of at least 50 million years of evolution.
In 1958, the Kerala State Electricity Board (KSEB) proposed building a hydroelectric dam across the Kunthipuzha River that would have submerged approximately 830 hectares of this rainforest. The project was approved by the Planning Commission in 1973, and Kerala desperately needed the electricity it would generate. But Parameswaran, along with environmentalist M.K. Prasad and others, brought rigorous scientific and economic scrutiny into the debate. The question was not simply whether one should love forests. It was whether destroying an irreplaceable ecological system was a rational way of producing electricity.
The campaign that followed brought together scientists, teachers, writers, students and ordinary citizens, subjecting a government project to a level of public scrutiny that was unusual for the time. Eventually, the hydroelectric project was abandoned and Silent Valley survived. The movement became a watershed in India’s environmental consciousness, establishing a model where communities could use scientific knowledge to question and challenge the definition of progress.
Parameswaran also played a significant role in the Athirappilly campaign against a proposed hydroelectric project on the Chalakudy River, which brought into sharp focus the conflict between electricity generation and the protection of one of Kerala’s most ecologically significant riverine landscapes. Later, he supported the concerns of local communities during the agitation against the Kudankulam nuclear power project in Tamil Nadu, a position that carried particular weight given his own background in nuclear engineering.
The Fourth World Theory
Perhaps the most intellectually provocative aspect of Parameswaran’s legacy was his “Fourth World” theory, presented in his book “Naalam Lokam: Swapnavum Yadharthyavum” (The Fourth World: Dream and Reality), published in 2004. The theory emerged in the aftermath of the collapse of the Soviet Union, which had triggered deep disillusionment within communist movements worldwide. Parameswaran was unwilling to simply accept capitalism as the only remaining model, but neither was he prepared to defend the old socialist model merely because it carried the Marxist label.
The Fourth World envisioned a society made up of a network of self-reliant local communities, with production and decision-making decentralised as far as possible. It drew from three intellectual streams: Karl Marx’s concern for equality and workers’ rights, Mahatma Gandhi’s vision of Gram Swaraj (village self-rule), and the environmental movement’s warning against limitless consumption. Technology was not to be rejected. It was to be used to make smaller communities more capable and less dependent on distant centres of power.
Expulsion from CPI(M)
The theory was controversial precisely because it challenged the certainties of orthodox Marxism. Parameswaran had been an active member of the Communist Party of India (Marxist), or CPI(M), for 33 years, having translated several of their foundational works into Malayalam, including “Dialectical Materialism” by Karl Marx and Friedrich Engels. The party evaluated the Fourth World as contrary to Marxist-Leninist principles and expelled him in February 2004.
The expulsion was not marked by bitterness. Parameswaran understood that the party had its own ideological framework rooted in dialectical materialism, and he respected that even when he disagreed with its conclusions. The party, in turn, appeared to recognise that his disagreements came from within the Left tradition and not from a rejection of it. As one obituary noted, the nuclear engineer who once worked with the most concentrated form of technological power eventually became an advocate of dispersing power, moving from the reactor to the village meeting, from high science to popular science, and from Marxist theory to the messy experiments of local democracy.
Parameswaran was also a member of the Sen Committee, appointed by the Kerala state government in 1996 to study the decentralisation of power, which contributed to Kerala’s landmark People’s Plan Campaign that devolved planning to local bodies.
Awards and Recognition
Over his long career, Parameswaran and the organisations he led received numerous national and international honours:
- Kerala Sree Award (2022): The third highest civilian award given by the Government of Kerala, recognising his contributions to science, social service and public life.
- Government of India Award for Books for Neoliterates (1962): One of his earliest recognitions for making knowledge accessible to new readers.
- Government of India Award for Basic and Cultural Literature (1964): Acknowledging his literary contributions.
- Children’s Literature Award (1982): For his work in making science accessible to young readers.
- UNESCO Literacy Award (1990): Bestowed on KSSP for its role in Kerala’s literacy campaigns.

- UNEP Global 500 Award and Vriksha Mitra Award: International recognition for KSSP’s environmental work.
In his later years, Parameswaran moved around in a wheelchair but continued to speak about science as a way of understanding nature rather than merely producing technology. He urged younger generations to reach out to ordinary citizens and inspire them to dream, a remarkable stance for a man who had spent a lifetime questioning grand promises.
