Rasayana Shasthrada Arivu

The main objectives of bringing out the kannada version Rasanashastrada Arivu is to introduce chemistry in a stimulating and exciting manner, to arouse the curiosity of the user and to generate more than a passing interest in chemistry in students and teachers in kannada medium schools and to tap the talent in these schools. We believe that this interactive CD-Rom authored by Professor C.N.R. Rao, an internationally acclaimed scientist and educationist, will go a long way in providing quality software for our kannada medium schools and further the cause of bridging the digital divide-a cherished goal of the Government of Karnataka. Rasayanashastrada Mahatva (Importance of Chemistry). This introduces the scope and importance of chemistry in all spheres of our activities and the role of chemistry in the modern world.
