The second part of the exciting fairytale space adventure! The Goldilocks continues to flee as the enemy hunts them down. During their escape into the Old Sultan Solar System, Commander Red and her computer companion Grimm encounter three space stations. Three little protectors named Pegg. These three monitor and protect the region of space around the core world inside the system. Red must reach that world if she is to save the Galactic Kingdom from certain doom. Is the mission in jeopardy? Will the Wolf Hunter vessel destroy them before they can reach their destination? Find out in this next instalment of the four-part sci fi/fantasy adventure series!

Sam West thought he knew what it was like to feel alone in the world. He had spent his fifteen years abandoned by his mother, neglected by his alcoholic father, and ignored by every foster parent he was sent to. At fifteen, Sam decides to find his mother in search of a future with the woman he barely remembers. But when his bush plane crashes en route in Northern Ontario, Canada, a vast expanse of untamed wilderness, Sam is the sole survivor and utterly alone. Determined to live and somehow make it back to civilization, Sam uses every ounce of knowledge to fight the elements, the treacherous predators, and most of all, to keep his head in the game of survival. After a near-death encounter with a bear shakes him to his core, the appearance of a mysterious mountain man surprises him the most. Together, they embark upon a long journey to find the world again, a world that will be forever different to these survivors. But Sam also finds something he never thought possible; he finds the friendship and the love he always wanted, forged in the solitary landscape of the wilderness.

Like having a private coach at their elbows, this introduction to algebra-based physics involves readers actively in a guided learn-by-doing process—sensing when they need a very patient exposition and when they need only minimal reinforcement, when they need to focus on concepts and when they need an opportunity to practice their quantitative skills. At the heart of the volume are worked examples in a unique, two-column format that focuses on the basic strategies and step-by-step thought processes involved in problem solving—with an emphasis on the relationship between the physical concepts and their mathematical expression. Color-coded drawings help readers visualize physics problems, and companion photographs show the same principle at work in different physical contexts, or juxtapose situations in which contrasting principles are at work. Real-world physics applications abound. Covers the full spectrum of topics in Mechanics, Thermal Physics, Electromagnetism, Light and Optics, and Modern Physics. For anyone needing an introduction to, or refresher of, algebra-based physics.

From the time when Charles Babbage first started construction of his difference engine through the construction of the Colossus computing machine and into the electronic micro circuit era the computer processing machine has undergone rapid and astounding development. From machines capable of carrying out a few calculations each minute the modern microprocessor is able to perform calculations in less than a second that the early machines would have taken over a thousand years to complete. This book winds back the clock almost 50 years to the dawn of the electronic microprocessor to show how a microprocessor can be built using only transistors. Includes all circuit diagrams and explanations on how they work through to the development of a fully functional unit that is capable of executing programs while displaying the inner workings of this amazing device. The reader can either follow the construction to build their own processor or just read through the process. Either way the information contained in this book should provide a source of interest for those who really want to understand how the processor at the core of almost every electronic system actually works.
