Dr r smith magic calculator reviews1/2/2023 Shakuntala Devi explained many of the methods she used to do mental calculations in her 1977 book Figuring: The Joy of Numbers. Writer Steven Smith commented, "the result is so far superior to anything previously reported that it can only be described as unbelievable." This event was recorded in the 1982 Guinness Book of World Records. These numbers were picked at random by the Department of Computing at Imperial College London. Her answer, which was 546,372,891, was confirmed by calculations done at the US Bureau of Standards by the UNIVAC 1101 computer, for which a special program had to be written to perform such a large calculation, which took a longer time than for her to do the same. In 1977, at Southern Methodist University, she gave the 23rd root of a 201-digit number in 50 seconds. Jensen published his findings in the academic journal Intelligence in 1990. Jensen reported that Devi provided the solution to the above-mentioned problems (395 and 15, respectively) before Jensen could copy them down in his notebook. Examples of the problems presented to Devi included calculating the cube root of 61,629,875 and the seventh root of 170,859,375. Jensen tested her performance at several tasks, including the calculation of large numbers. In 1988, she travelled to the US to have her abilities studied by Arthur Jensen, a professor of educational psychology at the University of California, Berkeley. She was on a tour of Europe throughout 1950 and was in New York City in 1976. Mental calculation ĭevi travelled to several countries around the world demonstrating her arithmetic talents. In 1944, Devi moved to London, United Kingdom. At the age of six she demonstrated her arithmetic abilities at the University of Mysore. She did this without any formal education. Her father left the circus and took her on road shows that displayed her ability at calculation. He discovered his daughter's ability to memorise numbers while teaching her a card trick when she was about three years old. Her father, C V Sundararaja Rao, worked as a trapeze artist, lion tamer, tightrope walker and magician in a circus. Shakuntala Devi was born on 4 November 1929 at Bangalore, Karnataka to a Kannada Brahmin family.
