As a writer and publisher

In 1939, he joined in the publication department of Visva Bharati, Shantiniketan. At that time, the world was terrified by the Second World War & the department had not sufficient money. But, even in this situation, Bhattacharya dared to publish the Rabindra Rochonaboli (Collected works by Rabindranath) and finally did it with Prashanta Chandra Mahalnabish, though these books were not of much demand.

Later, when Rabindranath Tagore planned to publish Bishwa Vidya Songroho and LokShiksha series of books to promote literacy, Bhattacharya performed this task. First book of LokShiksha was BishwaPorichoy by Tagore himself, which the poet dedicated to Satyendra Nath Bosu. In 1943, after two years of death of Tagore, Bhattacharya started writing more books of the Bishwa Vidya Songroho series. His first book was about the great scientist: Jagadish Chandra Bosu and named as Jagadish Chandrer Abishkar (Innovation of Jagadish) (1943). LokShiksha series consisted of 10 books, out of which 5 were of science, and out of nearly 150 books of BishwaVidyaSongroho, around 50 books were of science.

Pulin Bihari Sen, who was among the pioneers of Bengali publication, once told that,

...The main achievement of him is that, he has created a new hope in culture of science in Bengali by motivating a group of authors in this way.^[2]

He can be thought of as a successful successor to Jagadananda Roy & Ramendra Sundar Tribedi. His first book on popular science was Nabya Bijnan (Neo Science; 1918). Later, in 1926, his second book Ban(g)alir Khadyo (Food of Bengali) was published.

He had a deep connection with Bangiya Bijnan Parishad, founded by Satyendra Nath Bose. He was an active member of the first executive committee. He was elected the vice-president from 1949 to 1958, president during 1960–61. His article, Acharya Jagadish Chandra Bosu was published in the first issue of the famous magazine, Jnan O Bijnan, published from the organisation. Like Visva Bharati, this organisation also had LokBijnan and Bijnan Probesh series. First book of LokBijnan series was Bhattacharya's Toriter Avyutthan in 1949. The first 4 books of the Bijnan Probesh series were also written by him: Praromvo, PodarthoVidya in 3 volumes; all of these were published in 1949. On 31 December 1956, he was included in the trustee of Bongiya Bijnan Parishad.

After the demise of Rajshekhar Bosu, he delivered the First Rajshekhar Bosu Memorial Lecture, which later is published in a book entitled Poromanur Neucleus in 1962. A few more books in this context are: Acharya Jagadish Chandra Bosu (1938), Boijnanik Abishkarer Kahini (1953), Bishwer Upadan (1943), Byadhir Porajoy (1949), PodartoVidyar NoboJug (1951).

As an editor

In first life, Bhattacharya edited a magazine, Beporoya. Later he edited Bosudhara for a long time. Bhandar, the journal of Samabay Samiti was edited by him (during the 1926–1932 years). This magazine was also edited by Tagore.

As a preceptor

Besides writing on popular science, he wrote 2 textbooks of science for classes VI & VIII of West Bengal Board of Secondary Education. Bhattacharya contributed in making Bengali terminology a lot. Calcutta University once established a committee regarding this, where Rajshekhar Bosu was the president and Bhattacharya was the secretary. He also helped the Central Government of India regarding various measurement and terminologies of science. His articles are often found in many school level textbooks of literature in West Bengal.
