Igor Shelushkov
Igor Alexeyevich Shelushkov (born – ?) was a Soviet mental calculator. He mentally extracted nth root, roots of large numbers and calculated the number of syllables and characters in a given verse by listening. Shelushkov was featured in the 1968 Soviet popular science film ''Seven Steps Beyond the Horizon'', where he mentally extracted the sixth root of a 12-digit number and the 77th root of another multi-digit number. Shelushkov also competed with the Soviet third generation computer Mir. He extracted the 77th root of a 148-digit number in 18 seconds, while it took about 10 minutes to program the related operation for computer. Shelushkov was a postgraduate at Gorki Polytechnic Institute (now Nizhny Novgorod State Technical University). According to Shelushkov, he used the memorized logarithmic table for calculations. His abilities were mentioned by Russian mathematician Vladimir Tvorogov, who attended one of his performances, and by psychologist Artur Petrovsky. Shelushkov's su ...

Mental Calculator
Human calculator is a term to describe a person with a prodigious ability in some area of mental calculation (such as adding, subtracting, multiplying or dividing large numbers). The world's best mental calculators are invited every two years to compete for the Mental Calculation World Cup. On July 17, 2022, at Heinz Nixdorf MuseumsForum in Paderborn city of Germany, 12-year-old Indian mental calculator Aaryan Nitin Shukla clinched the title to become the new World Champion. Aaryan ended the dominance of Japanese mental calculators who won the competitions during 2018-Tomohiro Iseda and 2016-Yuki Kimura. Tomohiro Iseda (2018) was the third Japanese person to win the Cup, after Naofumi Ogasawara (2012) and Yuki Kimura (2016). Shakuntala Devi from India has been often mentioned on the Guinness World Records. Neelakantha Bhanu Prakash from India has been often mentioned on the Limca Book of Records for racing past the speed of a calculator in addition. Srilankan-Malaysian perfo ...

Nth Root
In mathematics, a radicand, also known as an nth root, of a number ''x'' is a number ''r'' which, when raised to the power ''n'', yields ''x'': :r^n = x, where ''n'' is a positive integer, sometimes called the ''degree'' of the root. A root of degree 2 is called a ''square root'' and a root of degree 3, a ''cube root''. Roots of higher degree are referred by using ordinal numbers, as in ''fourth root'', ''twentieth root'', etc. The computation of an th root is a root extraction. For example, 3 is a square root of 9, since 3 = 9, and −3 is also a square root of 9, since (−3) = 9. Any non-zero number considered as a complex number has different complex th roots, including the real ones (at most two). The th root of 0 is zero for all positive integers , since . In particular, if is even and is a positive real number, one of its th roots is real and positive, one is negative, and the others (when ) are non-real complex numbers; if is even and is a negative real numbe ...

Popular Science
''Popular Science'' (also known as ''PopSci'') is an American digital magazine carrying popular science content, which refers to articles for the general reader on science and technology subjects. ''Popular Science'' has won over 58 awards, including the American Society of Magazine Editors awards for its journalistic excellence in 2003 (for General Excellence), 2004 (for Best Magazine Section), and 2019 (for Single-Topic Issue). With roots beginning in 1872, ''Popular Science'' has been translated into over 30 languages and is distributed to at least 45 countries. Early history ''The Popular Science Monthly'', as the publication was originally called, was founded in May 1872 by Edward L. Youmans to disseminate scientific knowledge to the educated layman. Youmans had previously worked as an editor for the weekly ''Appleton's Journal'' and persuaded them to publish his new journal. Early issues were mostly reprints of English periodicals. The journal became an outlet for writings ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nizhny Novgorod State Technical University
Nizhny Novgorod State Technical University (russian: Нижегородский государственный технический университет им. Р. Е. Алексеева, NNSTU) is a public technical university in Nizhny Novgorod, Russia, founded in 1917. The university was renamed in honour of a famous alumnus, engineer Rostislav Alexeyev, in 1992.

Logarithm
In mathematics, the logarithm is the inverse function to exponentiation. That means the logarithm of a number to the base is the exponent to which must be raised, to produce . For example, since , the ''logarithm base'' 10 of is , or . The logarithm of to ''base'' is denoted as , or without parentheses, , or even without the explicit base, , when no confusion is possible, or when the base does not matter such as in big O notation. The logarithm base is called the decimal or common logarithm and is commonly used in science and engineering. The natural logarithm has the number as its base; its use is widespread in mathematics and physics, because of its very simple derivative. The binary logarithm uses base and is frequently used in computer science. Logarithms were introduced by John Napier in 1614 as a means of simplifying calculations. They were rapidly adopted by navigators, scientists, engineers, surveyors and others to perform high-a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Year Of Birth Uncertain
A year or annus is the orbital period of a planetary body, for example, the Earth, moving in Earth's orbit, its orbit around the Sun. Due to the Earth's axial tilt, the course of a year sees the passing of the seasons, marked by change in weather, the hours of daylight, and, consequently, vegetation and soil fertility. In temperate and subpolar climate, subpolar regions around the planet, four seasons are generally recognized: spring (season), spring, summer, autumn and winter. In tropics, tropical and subtropics, subtropical regions, several geographical sectors do not present defined seasons; but in the tropics#Seasons and climate, seasonal tropics, the annual wet season, wet and dry seasons are recognized and tracked. A calendar year is an approximation of the number of days of the Earth's orbital period, as counted in a given calendar. The Gregorian calendar, or modern calendar, presents its calendar year to be either a common year of 365 days or a leap year of 366 days, a ...
