Science historians have long acknowledged that the international numeral system (1,2, 3,), based on the concepts of placement and zero, as well as the decimal system were invented by the ancient Hindus. (Nonetheless many Western publications continue to call these numerals Arabic-- Arab historians themselves have always acknowledged the numerals' Hindu origins.)

An even more fundamental contribution to human knowledge-- the origin of alphabetic writing--must now be credited to the ancient Hindus. This claim arises from the deciphering of the ancient Indus script recently accomplished by Natwar Jha. In 1996, he published Vedic Glossary on Indus Seals, which briefly explained his methodology and presented readings of more than 100 seals. It was an English language summary of his monumental publications, Sindhu Mudra Lipi Bhasa, in Sanskrit, and Sindhu Sabhyata ki Mudraon ki Bhasa aur Lipi, in Hindi.
