India holds the reputation of being the birthplace of geniuses such as Aryabhatta. The man is well-known for apparently introducing the world to the digit ‘0(Zero)’, a mammoth contribution to the number theory. Famous physicians such as Charaka and Sushruta had even penned texts on the medicinal uses of plants, which continue to be useful in curing dreaded ailments even today. Other famous Indians who have contributed immensely to the field of science are Ramanujam, Sir C.V Raman, Homi Bhabha, M. Visvesvaraya, and J.C Bose. The discoveries of some of these sharp minds range from theories of mathematics such as Calculus to modern day nuclear physics. The Indian Space Research Organization, popularly known as ‘ISRO’ is considered to be one of the best space agencies in the world. Many scientists of the space agency worked together to make the nation proud with projects such as the ‘Mars Mission’ and the ‘Moon Mission’ etc. The achievements of these intelligent minds have also garnered a lot of appreciation from world over.
