MOZART composed his first symphony when he was five years old. Carl Friedrich Gauss, the famous German mathematician, made many discoveries while still a teenager. William Rowan Hamilton, the Irish mathematician, could speak 13 tongues when not yet 13. But what do you make of a nine-year-old who claims that the quark is not the smallest particle of matter, that he has found a way to calculate the exact value of pi, that he can predict earthquakes 15 days in advance, and that he probably knows the as-yet-mysterious composition of the iron pillar near Qutub Minar. Not to mention parlour tricks such as determining the day of any random date of your own choosing, or juggling numbers with admirable alacrity.
