All that is amazing enough.What is even more amazing is that a poem he wrote when he was not much more than a teenager explains all that he knew and learned without a single number,equation,or diagram.Aryabhate wanted his information to be easy to remember.So he put all the numbers into a code of letters and combinations of letters,which he explains at the beginning of the poem,called the Aryabhatiyam.Then,in 121 verses,he explains the way the planets move in the sky better than anyone else would for 1,000 years.For Aryabhate,astronomy was a way of understanding the deities.As he wrote,“One who knows these verses,one who knows the movements of planets and celestial spheres,goes much beyond them and attains the absolute Brahman.”
At first,people learned his poem and passed it on without writing it down.The fact that it wasn't written down at first may be one reason we still have it.Insects and mildew destroyed Indian manuscripts,which were written on birch bark or palm leaves,very quickly.
Oddly,Aryabhate seems not to have known about India's biggest contribution to math and science,although his students did.What is it? Zero.You know－nothing.Believe it or not,no one had ever considered zero a number before.Had that ever messed up their arithmetic!
If the number zero is nothing,why is it such a big deal? Because by using the number zero,people can write numbers in columns,which makes adding,subtracting,and especially multiplying and dividing much easier.
