Would you be able to tell, faster than a calculator, what is the square of a 3-digit number, to mentally calculate the day of the week for a given date or the square of a 5-digit number?

Arthur Benjamin proves that, using the right methods and techniques, the human brain is capable of such a performance. He even shows to the public the mental process he goes through and some of the mnemonic techniques he uses. Arthur Benjamin starts with relative simple calculations but finishes with an incredible performance.

His eloquence and the way he manages to pass the message to such a large TED audience are astonishing.
