Indian claims finding new cube root formula: "Agra: It has eluded experts for centuries, but now an Indian, following in the footsteps of Aryabhatt, one of the earliest Indian mathematicians, claims to have worked out a simple formula to find any number's cube root.
Nirbhay Singh Nahar, a retired chemical engineer and an amateur mathematician, claims he has found a formula that will help students and applied engineers to work out the cube roots of any number in a short time.
"Give me any number - even, odd, decimals, a fraction...and I will give you the cube root using a simple calculator to just add and subtract within a minute and a half. We do have methods and patterns, but no formula at the moment. Even the tables give cube roots of 1 to 1,000, not of fractions or of numbers beyond 1,000, for which people have to use scientific calculators," Nahar, who retired as an engineer from Hindustan Salts Ltd at Sambhar (Rajasthan), said."
