Teaching science in Lahore
Ruchi Ram Sahni was a scientist and educator associated with Government College and Panjab University in Lahore. A Panjab University account describes his teaching career and later work in Ernest Rutherford’s laboratory in Manchester, where he encountered research on radioactivity. It records papers published between 1915 and 1917 and his service in university bodies. Lahore was then part of an undivided Punjab under British rule. His work linked classroom teaching with research and with efforts to make scientific ideas accessible outside universities. His son Birbal Sahni later became a palaeobotanist, a scientist who studies fossil plants.[1]
Science for wider audiences
A chapter in Uncharted Terrains describes Sahni’s public science lectures, including talks about weather, electricity, air and familiar materials. It says he used demonstrations and gave Punjabi-language lectures in the compound of Baoli Sahib Gurdwara in Lahore. Lectures were also organised in other towns and at fairs. The chapter estimates that he delivered around 500 popular lectures, a retrospective estimate rather than a complete surviving count. Its examples show how he chose subjects connected to daily life and addressed audiences beyond the English-speaking classroom. Apparatus and demonstrations were part of how these ideas were presented.[2]
Explaining science in Punjabi
In his memoirs, Sahni argued that Punjabi could communicate scientific ideas. He recalled explaining wireless technology in both English and Punjabi at a gathering, and described another response to a popular lecture in Rawalpindi. These are his own retrospective accounts of particular occasions, not a survey of every listener’s understanding. They show that language choice mattered to him as an educator working in a multilingual setting. The memoir also describes the eventual closure of the Punjab Science Institute and the transfer of its resources to another scientific society. It is a first-person source for his view of that work.[3]
