Take a look in the picture above. This young 4 years boy who knew the alphabet backwards by the age of two has been invited to join Mensa. He is from Hampshire.
Harry Chapple, who is now four, is able to calculate the dimensions of circles and squared numbers in seconds, reports the Daily Telegraph.
A series of tests showed he has an IQ of 144 and now Harry has been invited to join Mensa - the society for people with an IQ over 130.
His dad Simon Chapple, 35, of Ash, Hants, said Harry showed an interest in maths from an early age and would ask for games involving numbers whenever they visited toy shops.
"Harry's always been very bright and naturally inquisitive," he said. "He's the kind of boy who'll ask you why the sky is blue and, when you tell him 'because it's reflecting the colour of the sea' he won't be satisfied.

"Harry's always been very bright and naturally inquisitive," he said. "He's the kind of boy who'll ask you why the sky is blue and, when you tell him 'because it's reflecting the colour of the sea' he won't be satisfied.
"He'll then ask 'why is the sea blue?' He's very persistent and curious. Harry's got a great memory and keeps all these formulas in his head like Pi which he uses to work out the circumference of circles."
Mr Chapple said that although he was also good at maths as a child and his wife Michelle, 29, also had a good memory they were stunned by Harry's 'incredible' ability.
The Chapples contacted Mensa, who used their own child psychologist George Crowther to carry out a series of tests.
Mr Crowther, a developmental psychologist for over 40 years, said: "Harry is an exceptional young boy and his ability is very rare.
"Only 0.1 per cent of people have an IQ over 140. In a secondary school of 1,000 pupils he could be the only one with that ability."
