President Pranab Mukherjee on Thursday launched ‘IMPRINT India’, a joint initiative of the country’s top educational institutes, aimed at developing a roadmap for research to solve major engineering and technology challenges relevant to India today. The initiative is based on Prime Minister Narendra Modi’s suggestion that research done by institutions of national importance must be linked with immediate requirements of the society at large. He said it is necessary to develop in our students a scientific temper, which allows the flight of imagination beyond the realm of grades and classrooms.
