A TIME TO GATHER STONES is a companion book to the author's earlier novel, ONE MAN'S WAR. The latter was the story of a young man caught up in The Great War of 1918. This is a continuation of his life, but told from the eyes of the sweetheart who wrote him so faithfully and became his wife. It is basically an account of a young woman faced with a widening world . The 1920's and 1930's change the role of women forever, and Lindy Jones moved with it. A person of inner strenghth amd a fierce determination she took up her role as a small-town wife and mother, a support to her husband and his career as a newspaper publisher and a leader among her peers. When her life reaches a time of crisis at the end, she meets the challenge head-on.

Solving Magic Squares is a fascinating and thrilling experience for many math enthusiasts. With the help of guiding steps, which are carefully explained in an easy-to-understand style, any magic square enthusiast can solve any type of magic square with ease.

A story book for all ages to experience mathematics, problems solving, and the rewards that come with perseverance."Long ago in the land of China, there were many rain storms ... and the land of China was slowly sinking into the sea. This is the story of how a wise emperor, an observant girl, and a magic turtle saved the villages of China from the great flood." So begins the story of Ying and the Magic Turtle. Children ages 5 and up, parents, and teachers can enjoy the book for its rich beauty in mathematics and as an ancient legend. It is the kind of story to revisit over and over again.This book is perhaps best experienced with someone, as a read-aloud or read-together. When reading, we learn of Ying's trouble, and we root for her to find her solution. We find ourselves drawn into the life problems that Ying is facing, but also drawn into the inherent mathematics of the story. It is through the beauty of the pattern of the dots on the turtle's shell that the solution is finally found and the land is saved.We can appreciate each scene as we read, and then pause and predict what might come next. We can play with the mathematics, solving right alongside Ying. We can delve deeper into the power of magic squares by working with puzzles presented at the end of the story. There are unsolved problems in number theory even a young child can try, such as finding all the possible magic squares of a given size.

Solving Magic Squares is a fascinating and thrilling experience for many math enthusiasts. With the help of guiding steps, which are carefully explained in an easy-to-understand style, any magic square enthusiast can solve any type of magic square with ease.

Fans of sudoku may not know that the game is a recent offshoot of the venerable Magic Square, which dates back more than 4,000 years to ancient China. This book provides a delightful account of the mind-boggling variety possible with magical squares.

The 4000 year- old mystery of Chinese magic squares is finally solved! Magic squares have fascinated ordinary and serious mathematicians alike for four thousand years. Great Yu discovered the first three by three magic square on the back of a turtle around the year 2200 B.C. before he was crowned the first emperor in China. Some three thousand years later in 1275, Yang Hui amused his countrymen with riddles describing the creations of third and fourth order magic squares. Two hundred forty years later in 1514, Albrecht Durer unknowingly applied Yang Hui's diagonal reversal scheme to produce in the Western world the first magic square. Some eighty years later in 1593, another Chinese mathematician Cheng Darwai produced a sixth-order magic square with a unique magic sum in every row, every column, but only in each of its twin diagonals knowns as the main and secondary diagonals. In this book, for the first time, F.Y. Chang has deciphered Yang Hui's riddles and extends both ancient Chinese mathematician's works and develops algorithms to create magic squares beyond the computation capacity of super computers. He formulates techniques such as parametric matrix formulation, row/column sum equalization, triple orthogonal transformation and diagonal switching for creation of the classical Chinese magic squares. He discovered the super diagonal Chinese magic squares with the magic sum in every generalized diagonal including the two conventional diagonals as well as an even number of four-segment split diagonals. Dr. Chang also introduces the idea of Chinese magic square games, which anyone of any age who is a number enthusiast can solve either by logical reasoning or by solving parametric linear equations.
