Well, if I list Chinese inventions here, the mod might call me spaming the thread... however, I know one invention Indians made: "0" .
How Indians invented "0 " ? It comes with a nice story:
Once upon a time, there was a gorilla in a deep forest...
one day, it found a banana on top of a tree and ate it...
the day after, since there wasn't any banana up there...
the gorilla was very upset...
"where was banana"- the gorilla was wondering...
Suddenly an Indian appeared behind the tree with a half banana
in his mouth...
"wow! who dare to steal my banana? " - the gorrila wondered...
Pity that since it was after 5 pm, just too dark for the gorilla
to identify how that Indian looked like except 2 lines of shining white teeth..
The peculiar wave of smell coming with the Indian made
the gorrila feel a bit dizzy...
"hmmm, it must be an Indian!", the gorrila immediately realised
what was going on:
if there was no Indian, there would be 1 banana;
if there was any Indian nearby, there would be no banana
---- concept of "0" !!!!
That Indian in the story was the next thing after the gorrila
to realise "0" !
See ? In this way Indians invented "0" !
Oh yes, in other words, Indians invented ZERO, or NIL !!
