It is a collection of 150 brain teasing math riddles and puzzles. Their purpose is to make children think and stretch the mind. They are designed to test logic, lateral thinking as well as memory and to engage the brain in seeing patterns and connections between different things and circumstances. They are laid out in three chapters which get more difficult as you go through the book, in the author’s opinion at least. The answers are at the back of the book if all else fails. These are more difficult riddles and are designed to be attempted by children from 10 years onwards, as well as participation from the rest of the family.

    It seemed as though the entire universe was holding its breath. Waiting. Whether waiting for the salvation of mankind or its demise was yet unclear.He set out to prove a theory. Now he’s racing to save the galaxy from his mistake.Along with his newly found, rag-tag band of alien friends, Nick Bannon battles to keep his devastating technology out of the hands of the biomechanoid race known as the Mok’tu.Nick is flung to a distant world when his hyperspace experiment goes awry. Technology can always be used for good or evil and now his peaceful experiment could become a horrific weapon of a malicious alien race. Every species in the galaxy is in danger of total annihilation and it may take one man’s greatest sacrifice to stop it.Full 86,000 word space opera novel!

I kept picturing Harrison Ford, but with the Indiana Jones personality, but in a Blade Runner world as Nick Bannon. The pacing was great, Swan did an awesome job giving just enough desription of the new technology and alien races without dragging the story into a grinding halt. The story had a feel good sense that I got from watching "Guardians of the Galaxy" - where you get to know the characters to the point where you actually want to meet themand have a few drinks at a dive bar to hear more stories.The dialogue and writing were top notch - and it was clear that this story was thought out before Swan committed it to paper. With all of the rehashes (really - can we do a Spiderman reboot just one more time please.....) it is nice to meet some new characters in a new adventure - and it doesn't have to end here, since Swan already has book two on the shelves.Highly recommend this book for lovers of sci fi!!!" - Nathan Merceron⭐️⭐️⭐️⭐️⭐️ "5 star sci-fi adventure - this book is FUN. The start of a new series, Book 1 : Awakenings does not disappoint. It has all the elements I desire in a good space adventure story - a reluctant hero fumbling his/her way through new alien space, interesting and unique aliens, exciting twists and turns, a good overall plot and a whole lot of fun. I am right on board the Hyperspace wagon, eagerly awaiting book 2, which means book 1 gets the OMGMOAR 5 star award from Tracing The Stars." -TracingTheStars.com ⭐️⭐️⭐️⭐️⭐️ "A lost Queen. An ancient prophecy. Worlds caught in an interstellar war between two malevolent alien races. Hyperspace, Nanites, Biomechanoids with a mysterious past. The Hyperspace Project is non-stop action and lots of fun." -John S.⭐️⭐️⭐️⭐️⭐️ "I really enjoyed this book. There is a lot of action, but it's well balanced. If you like Star Trek or shows like Stargate, then I think you'll like this book. Fun characters and a story that flows well. Some good futuristic science too. (Nanites, hyperspace, gadgets etc.) I only wish that the second book was already available. There is also an interesting extra chapter that can be unlocked with clues from the book. That added an extra bit of fun to it as well." -Sara, BestIndieBooks.com

    Fifteen extraordinary stories. One bestselling universe. It’s the Twenty-Second Century. The galaxy has opened up to humanity as a hyperactive beehive of stargates and new technologies, and we suddenly find ourselves in a vast playground of different races, environments, and cultures. There’s just one catch: we are pretty much at the bottom of the food chain, and there’s only one way for humanity to move up—by becoming mercenaries. In every mercenary’s life, though, there comes a time when things go wrong and even the best laid plans go awry. When they do, though, the best mercs fall back and work out new plans, and you can bet on one thing—hope is not their strategy. Whether you’re a kid looking to get off your planet, or an unarmed merc facing an overwhelming force, or even the sole survivor of a pirate attack, there’s always an edge—and it’s up to the merc to find and exploit it! Edited by bestselling authors and universe creators Chris Kennedy and Mark Wandrey, “Hope is Not a Strategy” includes all-new stories in the Four Horsemen universe by some of the bestselling Indie authors currently in the business. These authors take on various aspects of the universe, giving you additional insight into a galaxy that isn’t at war…but definitely isn’t at peace. There’s only one thing for sure in the 4HU—anything’s possible…for a fistful of credits! Inside, you’ll find: Preface by Chris Kennedy Golden Ticket by Jonathan P.

    This concept is at the root of the computational worldview, which basically says that very complex systems — the world we live in — have their beginnings in simple mathematical equations. We've lately come to understand that such an algorithm is only the start of a never-ending story — the real action occurs in the unfolding consequences of the rules. The chip-in-a-box computers so popular in our time have acted as a kind of microscope, letting us see into the secret machinery of the world. In Lifebox, Rucker uses whimsical drawings, fables, and humor to demonstrate that everything is a computation — that thoughts, computations, and physical processes are all the same. Rucker discusses the linguistic and computational advances that make this kind of "digital philosophy" possible, and explains how, like every great new principle, the computational world view contains the seeds of a next step.

    However, according to Hofstadter, the formal system that underlies all mental activity transcends the system that supports it. If life can grow out of the formal chemical substrate of the cell, if consciousness can emerge out of a formal system of firing neurons, then so too will computers attain human intelligence. Gödel, Escher, Bach is a wonderful exploration of fascinating ideas at the heart of cognitive science: meaning, reduction, recursion, and much more.

    From Mary, Queen of Scots, trapped by her own code, to the Navajo Code Talkers who helped the Allies win World War II, to the incredible (and incredibly simple) logisitical breakthrough that made Internet commerce secure, The Code Book tells the story of the most powerful intellectual weapon ever known: secrecy.Throughout the text are clear technical and mathematical explanations, and portraits of the remarkable personalities who wrote and broke the world’s most difficult codes. Accessible, compelling, and remarkably far-reaching, this book will forever alter your view of history and what drives it. It will also make you wonder how private that e-mail you just sent really is.

    For today, anyway. Because tomorrow I might be someone else. I can't tell you my real name, because I don't know what it is. The truth of the matter is that I don’t know who I am. You might be wondering how that can be. Join the club. My memories begin with overhearing two men planning my murder. You heard me, my murder. I get away from them, but just barely. The only things in my possession are a duffel bag with obscene amounts of cash and a wallet with four driver’s licenses. All with my picture. Don’t ask me how or why I have them – or even if any of them are real – because I don’t know. I don’t know much of anything. All I know is those men want me dead. For reasons still unknown to me. So I’ll run. And I’ll keep running until I can piece my fractured mind back together. But how do you go about remembering the things that most people already know?
