During summer vacation Rabindranath went to Almora with his family members. He took along with him sufficient numbers of Science books and some pictures drawn by Nandalal Bose. In Almora he wrote "Viswa Parichay" and Charar Chabi. he asked Prof. Pramathanath Sengupta of Santiniketan to write such a book. But ultimately, he took the responsibility in his own hands. He had to do much labour to find some scientific terms in Bengali. He had discussed with others for clearing his understanding of some topics.
Rabindranath had an idea in his mind to publish science books and to supply those books with minimum price to the ordinary people.
It was a fact that it would not have been possible for him to write such a book if Pramatha Babu did not prepare the structure of such a book.
After writing the book he dedicated it to Satyendranath Basu.
From the pictures of Nandalal Bose Rabindranath wrote some poems for the children which was converted to a book titled "Charar Chabi".
Rabindranath returned from Almora after about two months in 30th June, 1937. He went to Patisar, his zamindary state, for the last time.
