Yutaka Nishiyama (西山 豊, Nishiyama Yutaka, born 21 October 1948) is a Japanese mathematician and professor at the Osaka University of Economics, where he teaches mathematics and information. He is known as the "boomerang professor". He has written nine books about the mathematics in daily life. The most recent one, The mystery of five in nature, investigates, amongst other things, why many flowers have five petals.
John Horton Conway is an English mathematician active in the theory of finite groups, knot theory, number theory, combinatorial game theory and coding theory. He has also made contributions to many branches of recreational mathematics, most notably the invention of the cellular automaton called the Game of Life. Conway spent the first half of his long career at the University of Cambridge, in England, and the second half at Princeton University in New Jersey, where he now holds the title John von Neumann Professor Emeritus.
Martin John Dunwoody is an emeritus professor of Mathematics at the University of Southampton, England.
Gorō Shimura was a Japanese mathematician and Michael Henry Strater Professor Emeritus of Mathematics at Princeton University who worked in number theory, automorphic forms, and arithmetic geometry. He was known for developing the theory of complex multiplication of abelian varieties and Shimura varieties, as well as posing the Taniyama–Shimura conjecture which ultimately led to the proof of Fermat's Last Theorem.
Paul Anthony Samuelson was an American economist. The first American to win the Nobel Memorial Prize in Economic Sciences, the Swedish Royal Academies stated, when awarding the prize in 1970, that he "has done more than any other contemporary economist to raise the level of scientific analysis in economic theory". Economic historian Randall E. Parker has called him the "Father of Modern Economics", and The New York Times considered him to be the "foremost academic economist of the 20th century".
Sir James Alexander Mirrlees was a Scottish economist and winner of the 1996 Nobel Memorial Prize in Economic Sciences. He was knighted in the 1997 Birthday Honours.
Tenpō (天保) was a Japanese era name after Bunsei and before Kōka. The period spanned from December 1830 through December 1844. The reigning emperor was Ninko-tennō (仁孝天皇).
Michio Morishima was a heterodox economist and public intellectual who was the Sir John Hicks Professor of Economics at the London School of Economics from 1970–88. He was also professor at Osaka University and member of the British Academy. In 1976 he won the Order of Culture.
Dattatreya Ramchandra Kaprekar (1905–1986) was an Indian recreational mathematician who described several classes of natural numbers including the Kaprekar, Harshad and Self numbers and discovered the Kaprekar constant, named after him. Despite having no formal postgraduate training and working as a schoolteacher, he published extensively and became well known in recreational mathematics circles.
Dan Pedoe was an English-born mathematician and geometer with a career spanning more than sixty years. In the course of his life he wrote approximately fifty research and expository papers in geometry. He is also the author of various core books on mathematics and geometry some of which have remained in print for decades and been translated into several languages. These books include the three-volume Methods of Algebraic Geometry, The Gentle Art of Mathematics, Circles: A Mathematical View, Geometry and the Visual Arts and most recently Japanese Temple Geometry Problems: San Gaku.
Sir Partha Sarathi Dasgupta, FRS, FBA, is an Indian-British economist who is the Frank Ramsey Professor Emeritus of Economics at the University of Cambridge, United Kingdom; Fellow of St John's College, Cambridge, and Visiting Professor at the New College of the Humanities, London.

Hua Luogeng or Hua Loo-Keng was a Chinese mathematician and politician famous for his important contributions to number theory and for his role as the leader of mathematics research and education in the People's Republic of China. He was largely responsible for identifying and nurturing the renowned mathematician Chen Jingrun who proved Chen's theorem, the best known result on the Goldbach conjecture. In addition, Hua's later work on mathematical optimization and operations research made an enormous impact on China's economy. He was elected a foreign associate of the US National Academy of Sciences in 1982. He was elected a member of the standing Committee of the first to sixth National people's Congress, Vice-Chairman of the sixth National Committee of the Chinese People's Political Consultative Conference and Vice-Chairman of the China Democratic League (1979).

Penney's game, named after its inventor Walter Penney, is a binary (head/tail) sequence generating game between two players. Player A selects a sequence of heads and tails, and shows this sequence to player B. Player B then selects another sequence of heads and tails of the same length. Subsequently, a fair coin is tossed until either player A's or player B's sequence appears as a consecutive subsequence of the coin toss outcomes. The player whose sequence appears first wins.
Yutaka Yaguchi is the Chief Instructor and Chairman of the International Shotokan Karate Federation (ISKF) Mountain States Region. He was born in Hiroshima, Japan, in 1932 and began karate training in 1952. He later tested under masters Gichin Funakoshi for his 1st dan black belt and Masatoshi Nakayama for his 2nd through 8th dan black belts. As one of the first graduates of the Japan Karate Association (JKA) Instructors' Training Program in 1959, he has played an important role in the growth of JKA karate and the internationalization of Shotokan karate. Yaguchi first arrived in the United States on June 5, 1965, and continues to reside in the US to the present day. In 1974, Yaguchi founded the ISKF of Colorado, the regional headquarters for the Mountain States Region.
Herbert Gintis is an American economist, behavioral scientist, and educator known for his theoretical contributions to sociobiology, especially altruism, cooperation, epistemic game theory, gene-culture coevolution, efficiency wages, strong reciprocity, and human capital theory. Throughout his career, he has worked extensively with economist Samuel Bowles. Their landmark book, Schooling in Capitalist America, has had multiple editions in five languages since it was first published in 1976. Their most recent book, A Cooperative Species: Human Reciprocity and its Evolution was published by Princeton University Press in 2011.
Frank Horace Hahn FBA was a British economist whose work focused on general equilibrium theory, monetary theory, Keynesian economics and monetarism. A famous problem of economic theory, the conditions under which money can have a positive value in a general equilibrium, is called "Hahn's problem" after him.
