Prime Minister Narendra Modi today pitched for using vernacular languages in promoting science communication in a "big way" to develop "love of science" in the youth, saying language should not be a barrier but a facilitator. Addressing the curtain-raiser ceremony of the commemoration of professor Satyendra Nath Bose's 125th birth anniversary in Kolkata via video-conference, he said Bose was a "crusader" for teaching of science in vernacular languages and had started a Bengali science magazine.
