The Japanese Abacus & Theory book is easy to follow, and gives the reader step-by-step directions on how to use it correctly while applying it to practical use. The imperfect numerical notation and scarcity of suitable writing materials in ancient times are presumed to have given rise to need for devices of mechanical calculation. While the definite origin of the abacus is obscure, there is some reason for believing that its earliest form reckoning table covered with sand or fine dust, in which figures were drawn with a stylus, to be erased with the figure when necessary. Though the Abacus is an older tool for calculation it still is used today in Japan taking on a different name called Soroban. Though the Japanese Abacus or Soroban may appear mysterious or even primitive to those raised in the age of pocket calculators and desktop computers, this intriguing tool is capable of amazing speed and accuracy. It is still widely used throughout the shops and markets of Asia, and its popularity shows no sign of decline. Here for the first time in English is a complete explanation of how to use the abacus.

Seki was a Japanese mathematician in the seventeenth century known for his outstanding achievements, including the elimination theory of systems of algebraic equations, which preceded the works of Étienne Bézout and Leonhard Euler by 80 years. Seki was a contemporary of Isaac Newton and Gottfried Wilhelm Leibniz, although there was apparently no direct interaction between them. The Mathematical Society of Japan and the History of Mathematics Society of Japan hosted the International Conference on History of Mathematics in Commemoration of the 300th Posthumous Anniversary of Seki in 2008. This book is the official record of the conference and includes supplements of collated texts of Seki's original writings with notes in English on these texts. Hikosaburo Komatsu (Professor emeritus, The University of Tokyo), one of the editors, is known for partial differential equations and hyperfunction theory, and for his study on the history of Japanese mathematics. He served as the President of the International Congress of Mathematicians Kyoto 1990.

Building the Foundation: Whole Numbers in the Primary Grades

The 23rd ICMI Study

Author: Maria G. Bartolini Bussi,Xu Hua Sun

Publisher: Springer

ISBN: 3319635557

Category: Education

Page: 536

View: 496

This twenty-third ICMI Study addresses for the first time mathematics teaching and learning in the primary school (and pre-school) setting, while also taking international perspectives, socio-cultural diversity and institutional constraints into account. One of the main challenges of designing the first ICMI primary school study of this kind is the complex nature of mathematics at the early level. Accordingly, a focus area that is central to the discussion was chosen, together with a number of related questions. The broad area of Whole Number Arithmetic (WNA), including operations and relations and arithmetic word problems, forms the core content of all primary mathematics curricula. The study of this core content area is often regarded as foundational for later mathematics learning. However, the principles and main goals of instruction on the foundational concepts and skills in WNA are far from universally agreed upon, and practice varies substantially from country to country. As such, this study presents a meta-level analysis and synthesis of what is currently known about WNA, providing a useful base from which to gauge gaps and shortcomings, as well as an opportunity to learn from the practices of different countries and contexts.

Here's Looking at Euclid

A Surprising Excursion Through the Astonishing World of Math

Author: Alex Bellos

Publisher: Simon and Schuster

ISBN: 1416596348

Category: Mathematics

Page: 336

View: 1222

Too often math gets a bad rap, characterized as dry and difficult. But, Alex Bellos says, "math can be inspiring and brilliantly creative. Mathematical thought is one of the great achievements of the human race, and arguably the foundation of all human progress. The world of mathematics is a remarkable place." Bellos has traveled all around the globe and has plunged into history to uncover fascinating stories of mathematical achievement, from the breakthroughs of Euclid, the greatest mathematician of all time, to the creations of the Zen master of origami, one of the hottest areas of mathematical work today. Taking us into the wilds of the Amazon, he tells the story of a tribe there who can count only to five and reports on the latest findings about the math instinct—including the revelation that ants can actually count how many steps they’ve taken. Journeying to the Bay of Bengal, he interviews a Hindu sage about the brilliant mathematical insights of the Buddha, while in Japan he visits the godfather of Sudoku and introduces the brainteasing delights of mathematical games. Exploring the mysteries of randomness, he explains why it is impossible for our iPods to truly randomly select songs. In probing the many intrigues of that most beloved of numbers, pi, he visits with two brothers so obsessed with the elusive number that they built a supercomputer in their Manhattan apartment to study it. Throughout, the journey is enhanced with a wealth of intriguing illustrations, such as of the clever puzzles known as tangrams and the crochet creation of an American math professor who suddenly realized one day that she could knit a representation of higher dimensional space that no one had been able to visualize. Whether writing about how algebra solved Swedish traffic problems, visiting the Mental Calculation World Cup to disclose the secrets of lightning calculation, or exploring the links between pineapples and beautiful teeth, Bellos is a wonderfully engaging guide who never fails to delight even as he edifies. Here’s Looking at Euclid is a rare gem that brings the beauty of math to life.

The Anthropology of Numbers

Why do the Nuer stipulate forty cattle in brideprice? Why is the number ten so important in North American mythology? What does the anthropologist Clifford Geertz really mean to say when he talks about the correspondence of Balinese time cycles? Numbers play some part, often quite central, in almost all known cultures, yet until now the subject has never been examined in detail from an anthropological perspective. This book is the first attempt to find out how people in a wide range of diverse cultures and in different historical contexts, use and understand numbers. The opening chapters provide the basis for looking at the way numbers operate in different contexts, by looking at the logical, psychological and linguistic implications. The following eight chapters deal with specific themes: ethnoscience, politics, measurement, time, money, music, games and architecture. The final chapter relates such operations to social, economic and cultural factors.

Furious George

My Forty Years Surviving NBA Divas, Clueless GMs, and Poor Shot Selection

The most outspoken and combative coach in NBA history—and one of the most successful, amassing more than 1,175 victories, the sixth best winning record ever—reflects on his life, his career, and his battles on and off the basketball court in this no-holds-barred memoir A man of deep passion and intensity, George Karl earned his bad boy reputation while playing at the University of North Carolina, a rap that continued through the five years he spent with the San Antonio Spurs—and long after he stopped playing. Karl’s beery nights, fistfights, and barking followed him into a thirty-five-year coaching career. In a game defined by big stakes and bigger egos, rabid fans and an unforgiving media, Karl was hired and fired a dozen times. After leading a team beset by injuries and with no superstar to its best season of all time—an achievement that earned Karl the title NBA Coach of the Year—he was dumped by the Denver Nuggets in 2013. Less than a year and a half later, Karl was at the helm of the Sacramento Kings, snarling and bellowing on the sidelines before being cut loose in May 2016. Intense, obstinate, and loud, Karl has never backed down from a confrontation, whether with management, officials, or star players, as NBA legends from Allan Iverson to Gary Payton to Carmelo Anthony to Demarcus Cousins can attest. Telling his story, Karl holds nothing back as he speaks out about the game that has defined his life, including the greed, selfishness, and ass-covering he believes are characteristic of the modern NBA player, and the rampant corruption that leads all the way to the office of the NBA commissioner, David Stern. Karl also reveals how he’s learned to deal with the personalities, the pressure, and the setbacks with a resilience he acquired from his three bouts with cancer. Raw, hard-hitting, and brutally honest, Furious George is as thrilling, unpredictable, and entertaining as the game that has defined Karl’s life.

Mathematics is beautiful--and it can be fun and exciting as well as practical. Good Math is your guide to some of the most intriguing topics from two thousand years of mathematics: from Egyptian fractions to Turing machines; from the real meaning of numbers to proof trees, group symmetry, and mechanical computation. If you've ever wondered what lay beyond the proofs you struggled to complete in high school geometry, or what limits the capabilities of computer on your desk, this is the book for you. Why do Roman numerals persist? How do we know that some infinities are larger than others? And how can we know for certain a program will ever finish? In this fast-paced tour of modern and not-so-modern math, computer scientist Mark Chu-Carroll explores some of the greatest breakthroughs and disappointments of more than two thousand years of mathematical thought. There is joy and beauty in mathematics, and in more than two dozen essays drawn from his popular "Good Math" blog, you'll find concepts, proofs, and examples that are often surprising, counterintuitive, or just plain weird. Mark begins his journey with the basics of numbers, with an entertaining trip through the integers and the natural, rational, irrational, and transcendental numbers. The voyage continues with a look at some of the oddest numbers in mathematics, including zero, the golden ratio, imaginary numbers, Roman numerals, and Egyptian and continuing fractions. After a deep dive into modern logic, including an introduction to linear logic and the logic-savvy Prolog language, the trip concludes with a tour of modern set theory and the advances and paradoxes of modern mechanical computing. If your high school or college math courses left you grasping for the inner meaning behind the numbers, Mark's book will both entertain and enlighten you.
