Perfect for fans of Korman’s Ungifted and the Masterminds series, as well as Carl Hiaasen’s eco mysteries. As the son of the world’s most famous tech billionaire, spoiled Jett Baranov has always gotten what he wanted. So when his father’s private jet drops him in the middle of the Arkansas wilderness, at a place called the Oasis, Jett can’t believe it.

As the weeks go on, Jett starts to get used to the unplugged life and even bonds with the other kids over their discovery of a baby-lizard-turned-pet, Needles. But he can’t help noticing that the adults at the Oasis are acting really strange.

They can stand in line (sort of), use indoor voices (perhaps), and are capable of sharing (rumor has it), so the Click Clack critters are ready for school…but is school ready for them? A charming addition to the award-winning Click, Clack series from the New York Times bestselling and Caldecott winning team who brought you Click, Clack, Moo and Click, Clack, Surprise! Farmer Brown has been invited to be a guest at the elementary school’s Farm Day! The animals excitedly practice their best classroom behavior: standing quietly in line, using their inside voices, and learning how to share. But then they find out that farm animals aren’t actually allowed in school (who knew they were considered a health code violation?!). Rules are rules, so Farmer Brown goes to school solo—or so he thinks…for while our favorite barnyard bunch don’t get high marks in rules, they do excel in disguise.

Capricorn (Cap) Anderson has never watched television. He's never tasted a pizza. Never heard of a wedgie. Since he was little, his only experience has been living on a farm commune and being home-schooled by his hippie grandmother, Rain. But when Rain falls out of a tree while picking plums and has to stay in the hospital, Cap is forced to move in with a guidance counselor and her cranky teen daughter and attend the local middle school. While Cap knows a lot about tie-dying and Zen Buddhism, no education could prepare him for the politics of public school. Right from the beginning, Cap's weirdness makes him a moving target at Claverage Middle School (dubbed C-Average by the students). He has long, ungroomed hair; wears hemp clothes; and practises tai chi on the lawn. Once Zack Powers, big man on campus, spots Cap, he can't wait to introduce him to the age-old tradition at C-Average: the biggest nerd is nominated for class president—and wins.

Algorithms specify the way computers process information and how they execute tasks. Many recent technological innovations and achievements rely on algorithmic ideas – they facilitate new applications in science, medicine, production, logistics, traffic, communi¬cation and entertainment. Efficient algorithms not only enable your personal computer to execute the newest generation of games with features unimaginable only a few years ago, they are also key to several recent scientific breakthroughs – for example, the sequencing of the human genome would not have been possible without the invention of new algorithmic ideas that speed up computations by several orders of magnitude. The greatest improvements in the area of algorithms rely on beautiful ideas for tackling computational tasks more efficiently. The problems solved are not restricted to arithmetic tasks in a narrow sense but often relate to exciting questions of nonmathematical flavor, such as: How can I find the exit out of a maze? How can I partition a treasure map so that the treasure can only be found if all parts of the map are recombined? How should I plan my trip to minimize cost? Solving these challenging problems requires logical reasoning, geometric and combinatorial imagination, and, last but not least, creativity – the skills needed for the design and analysis of algorithms. In this book we present some of the most beautiful algorithmic ideas in 41 articles written in colloquial, nontechnical language. Most of the articles arose out of an initiative among German-language universities to communicate the fascination of algorithms and computer science to high-school students. The book can be understood without any prior knowledge of algorithms and computing, and it will be an enlightening and fun read for students and interested adults.
