In Then Again, the third installment of Division By Zero, MiFiWriters brings you stories of time. Six different Michigan authors explore the paradoxes and unexpected consequences that come from time travel, alternate realities, or general meddling in the space-time continuum.

The common sense on the division by zero with the long and mysterious history is wrong and our basic idea on the space around the point at infinity is also wrong since Euclid. On the gradient or on differential coefficients we have a great missing since tan(π/2) = 0. Our mathematics is also wrong in elementary mathematics on the division by zero. In this book in a new and definite sense, we will show and give various applications of the division by zero 0/0 = 1/0 = z/0 = 0. In particular, we will introduce several fundamental concepts in calculus, Euclidean geometry, analytic geometry, complex analysis and differential equations. We will see new properties on the Laurent expansion, singularity, derivative, extension of solutions of differential equations beyond analytical and isolated singularities, and reduction problems of differential equations. On Euclidean geometry and analytic geometry, we will find new fields by the concept of the division by zero. We will collect many concrete properties in mathematical sciences from the viewpoint of the division by zero. We will know that the division by zero is our elementary and fundamental mathematics.

Aircraft Engineering Principles is the essential text for anyone studying for licensed A&P or Aircraft Maintenance Engineer status. The book is written to meet the requirements of JAR-66/ECAR-66, the Joint Aviation Requirement (to be replaced by European Civil Aviation Regulation) for all aircraft engineers within Europe, which is also being continuously harmonised with Federal Aviation Administration requirements in the USA. The book covers modules 1, 2, 3, 4 and 8 of JAR-66/ECAR-66 in full and to a depth appropriate for Aircraft Maintenance Certifying Technicians, and will also be a valuable reference for those taking ab initio programmes in JAR-147/ECAR-147 and FAR-147. In addition, the necessary mathematics, aerodynamics and electrical principles have been included to meet the requirements of introductory Aerospace Engineering courses. Numerous written and multiple choice questions are provided at the end of each chapter, to aid learning.

Moving to America turns H&à's life inside out. For all the 10 years of her life, H&à has only known Saigon: the thrills of its markets, the joy of its traditions, the warmth of her friends close by, and the beauty of her very own papaya tree. But now the Vietnam War has reached her home. H&à and her family are forced to flee as Saigon falls, and they board a ship headed toward hope. In America, H&à discovers the foreign world of Alabama: the coldness of its strangers, the dullness of its food, the strange shape of its landscape, and the strength of her very own family. This is the moving story of one girl's year of change, dreams, grief, and healing as she journeys from one country to another, one life to the next.
