Tribute to MP Parameswaran, Scientist and Activist, Dies at 92
A very smart scientist named MP Parameswaran passed away at his home in Thrissur, Kerala.
He was 92 years old.
He had a good, comfortable job at a famous atomic research centre, but he gave it up to teach science to everyday people.
He believed that thinking like a scientist protects people from superstition and unfair beliefs.
He helped build groups that spread science and ran big reading and literacy campaigns.
He wrote almost 100 books about space, math, energy, nature, and other topics.
He was a member of a political party, but he always wanted to think for himself.
The party expelled him in 2004 because he disagreed with some party ideas.
He never changed his beliefs, even when that made things hard for him.
Many people respected him for being honest, brave, and curious, and they remember him as a rare public teacher.
MP Parameswaran died at his home in Thrissur, Kerala, on Tuesday at the age of 92.
He left his comfortable job as a scientist at the Bhabha Atomic Research Centre to work full-time as a political and social activist taking science to ordinary people.
A leading figure of the Kerala Sastra Sahithya Parishad, he helped build the All India People's Science Network and the Bharat Gyan Vigyan Samiti, which supported literacy campaigns.
He was expelled from the CPI(M) in 2004 for indiscipline after his ideas, expressed in his book The Fourth World, provoked a prolonged controversy within the party.
He wrote nearly 100 books on subjects including atomic energy, radioactivity, astronomy, mathematics, ecology, education, and political economy.
