India's discovery

Technology has taken all of us far ahead. The silicon civilization has made tremendous advancement in our day to day life. And we all bow to the western countries for their contribution.
Well if we see our country in the same field, we have made fast developments. But that's not deniable that we lack somewhere or the other in it(that is a major reason of our today's Engineers drain to west).
But we are talking about the discovery of India. So the discovery I want to tell is ZERO. We all know that आर्यभट discovered or rather formulated this symbol. The symbol has no value but has it all the other way round. When made in group, it has a meaning but alone its useless.
The symbol 'O' was so formulated to be quickly made as it is the mostly used numeral.
But why am I talking this with reference to computers??
Well that's the main thought....
we know computers work on binary system..so if hadn't there been a discovery of zero..there wouldn't have been any binary numbers.
what would have symbolized 'off' mode??
well may be then the things would have been different..but the moral of the story is...you cannot deny the existence of India in any field..
so be proud of your country..INDIA....
