    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.

    For some of us, the word conjures up memories of ten-pound textbooks and visions of tedious abstract equations. And yet, in reality, calculus is fun, accessible, and surrounds us everywhere we go. In Everyday Calculus, Oscar Fernandez shows us how to see the math in our coffee, on the highway, and even in the night sky.Fernandez uses our everyday experiences to skillfully reveal the hidden calculus behind a typical day's events. He guides us through how math naturally emerges from simple observations-how hot coffee cools down, for example-and in discussions of over fifty familiar events and activities. Fernandez demonstrates that calculus can be used to explore practically any aspect of our lives, including the most effective number of hours to sleep and the fastest route to get to work. He also shows that calculus can be both useful-determining which seat at the theater leads to the best viewing experience, for instance-and fascinating-exploring topics such as time travel and the age of the universe. Throughout, Fernandez presents straightforward concepts, and no prior mathematical knowledge is required. For advanced math fans, the mathematical derivations are included in the appendixes.Whether you're new to mathematics or already a curious math enthusiast, Everyday Calculus invites you to spend a day discovering the calculus all around you. The book will convince even die-hard skeptics to view this area of math in a whole new way.

    He continues to challenge our understanding of history."--Philip Coppens, author of The Ancient Alien QuestionAncient humans had the natural urge to document the world in which they lived, a fact that is evident in the cave paintings and carvings that still exist today. Why do rock paintings from various sites around the world all seem to depict the same things? Did the peoples of the prehistoric world have contact with each another? Is it possible that some were transported to far-flung locations in what our ancestors could only have described as "flying chariots"?Erich von Daniken, one of the best-selling authors of all time and regarded by many as the father of the ancient alien theory, continues his mission to uncover Earth's ancient past--this time with more than 150 extraordinary full-color photographs--in Evidence of the Gods.This extensively illustrated book features never-before-seen photographs from his unique archive, compiled throughout decades of searching around the world for traces of the cosmic gods whom he believes came to Earth thousands of years ago. Evidence of the Gods offers the best and most impressive evidence to date, along with concise explanations for the images, to bolster the case that von Daniken has already been making quite convincingly for years.Evidence of the Gods is his most convincing--and thoroughly entertaining--work yet.Did extraterrestrial visitors really leave their unmistakable traces on our planet thousands of years ago?The images will speak for themselves.
