Chandrasekhar, S.N. Bose) periods. The beautiful number system (zero and decimal system) invented by the Indians on which mathematical development has rested is complimented by Laplace. ‘The ingenious method of expressing every possible number using a set of ten symbols (each SYMBOL having a place value and an absolute value) emerged in India. The idea seems so simple nowadays that its significance and profound importance is no longer appreciated. Its simplicity lies in the way it facilitated calculation and placed arithmetic foremost amongst useful inventions. The importance of this invention is more readily appreciated when one considers that it was beyond the two greatest men of ANTIQUITY, Archimedes and Apollonius. It was Einstein who said we should be grateful to Indians who taught us how to count.’ While the rest of the world was in the dark ages, India made strides in mathematics and holds a 3000-year legacy through the works of Sulbakaras (800–600 BCE), Aryabhata, Varahamihira, Brahmagupta, Bhaskaracharya, Samgamagrama Madhavan, Nilakanda Somayaji, Jyestadeva, Sankaravarman extending to Srinivasa Ramanujan, S N Bose, Harish Chandra Prasanta Chandra Mahalanobis and reaching to the current period of Narendra Karmakar, Jayan Narlikar, S.R. Srinivasa Varadhan, E.C.G. Sudarsan and Thanu Padmanabhan.
