Introduction to the mathematics involved in designing identification codes for everyday goods.

Lev Grossman’s new novel THE BRIGHT SWORD will be on sale July 2024 The New York Times bestselling novel about a young man practicing magic in the real world, now an original series on SYFY “The Magicians is to Harry Potter as a shot of Irish whiskey is to a glass of weak tea. . . . Hogwarts was never like this.” —George R.R. Martin “Sad, hilarious, beautiful, and essential to anyone who cares about modern fantasy.” —Joe Hill “A very knowing and wonderful take on the wizard school genre.” —John Green “The Magicians may just be the most subversive, gripping and enchanting fantasy novel I’ve read this century.” —Cory Doctorow “This gripping novel draws on the conventions of contemporary and classic fantasy novels in order to upend them . . . an unexpectedly moving coming-of-age story.” —The New Yorker “The best urban fantasy in years.” —A.V. Club Quentin Coldwater is brilliant but miserable. A high school math genius, he’s secretly fascinated with a series of children’s fantasy novels set in a magical land called Fillory, and real life is disappointing by comparison. When Quentin is unexpectedly admitted to an elite, secret college of magic, it looks like his wildest dreams have come true. But his newfound powers lead him down a rabbit hole of hedonism and disillusionment, and ultimately to the dark secret behind the story of Fillory. The land of his childhood fantasies turns out to be much darker and more dangerous than he ever could have imagined. . . . The prequel to the New York Times bestselling book The Magician King and the #1 bestseller The Magician's Land, The Magicians is one of the most daring and inventive works of literary fantasy in years. No one who has escaped into the worlds of Narnia and Harry Potter should miss this breathtaking return to the landscape of the imagination.

The Fundamental Principle of Digits of a Number is a new mathematical idea for which the author received a copyright from the United States Library of Congress. Two related concepts make it easy to understand and apply the principle. The first concept is that a permutation of digits of a given number is an arrangement of the digits of the given number in any order such that the numerical quantity, which results from the arrangement of the digits of the given number, has the same digits and the same number of digits as the given number. The second concept is that the difference between two permutations of digits of a given number is governed by a mathematical law which guarantees that the difference is divisible by 9. One day, the number 12 suddenly appeared on the author’s inner eye. It turned around and formed the number 21. The two numbers subtracted, and number 9 appeared. Then the three numbers disappeared from the author’s inner eye. The motion of the numbers by their own power, as if they were birds in the sky, prompted Chibamba Mulenga to investigate this event with digits of other numbers, leading to his discovery of this mathematical principle.

"The numbers one through nine have remarkable mathematical properties and characteristics. For instance, why do eight perfect card shuffles leave a standard deck of cards unchanged? Are there really "six degrees of separation" between all pairs of people? And how can any map need only four colors to ensure that no regions of the same color touch? In Single Digits, Marc Chamberland takes readers on a fascinating exploration of small numbers, from one to nine, looking at their history, applications, and connections to various areas of mathematics, including number theory, geometry, chaos theory, numerical analysis, and mathematical physics."--Jacket.

Not long after research began at RAND in 1946, the need arose for random numbers that could be used to solve problems of various kinds of experimental probability procedures. These applications, called Monte Carlo methods, required a large supply of random digits and normal deviates of high quality, and the tables presented here were produced to meet those requirements.This book was a product of RAND's pioneering work in computing, as well a testament to the patience and persistence of researchers in the early days of RAND. The tables of random numbers in this book have become a standard reference in engineering and econometrics textbooks and have been widely used in gaming and simulations that employ Monte Carlo trials. Still the largest published source of random digits and normal deviates, the work is routinely used by statisticians, physicists, polltakers, market analysts, lottery administrators, and quality control engineers. A 2001 article in the New York Times on the value of randomness featured the original edition of the book, published in 1955 by the Free Press. The rights have since reverted to RAND, and in this digital age, we thought it appropriate to reissue a new edition of the book in its original format, with a new foreword by Michael D. Rich, RAND's Executive Vice President
