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.
Four years, thousands of sums, a lot of painstaking research and total devotion led him to develop the formula which he has now
copyrighted.
"I am willing to be scrutinised and investigated by anyone in the world, and to demonstrate but I will not disclose the formula till it is patented because I want the credit for my work to go to India, my country," he added.
