193. Empire of Numbers: The Indian Origin of Arabic Numerals

Often called Arabic numerals, the modern number system we use today actually originates in India. Whilst in the west they were using Roman numerals, in India they were using numbers 1-9. Then, the great Brahmagupta in the 7th century made one of the most monumental developments in human history. He invented zero in its modern form. Therefore, these basic rules of mathematics for the first time allowed any number up to infinity to be expressed with just ten distinct symbols: the nine Indian numbers plus zero. Rules that are still taught in classrooms around the world today. This step was a major advance that had never previously been attempted elsewhere and it was this Indian reincarnation of zero as a number, rather than just as an absence, that transformed it and gave it its power. From India, this development then travelled along the Golden Road and into the heart of Barmakid Baghdad.
