    Demonstrates the programming language's strength as a Web development tool, covering syntax, data types, built-ins, the Python standard module library, and real world examples

    Emphasis is placed on understanding the crisp mathematical idea behind each algorithm, in a manner that is intuitive and rigorous without being unduly formal. Features include: The use of boxes to strengthen the narrative: pieces that provide historical context, descriptions of how the algorithms are used in practice, and excursions for the mathematically sophisticated.Carefully chosen advanced topics that can be skipped in a standard one-semester course, but can be covered in an advanced algorithms course or in a more leisurely two-semester sequence.An accessible treatment of linear programming introduces students to one of the greatest achievements in algorithms. An optional chapter on the quantum algorithm for factoring provides a unique peephole into this exciting topic. In addition to the text, DasGupta also offers a Solutions Manual, which is available on the Online Learning Center.Algorithms is an outstanding undergraduate text, equally informed by the historical roots and contemporary applications of its subject. Like a captivating novel, it is a joy to read. Tim Roughgarden Stanford University

    Her adjustment to a new culture includes shocking doses of American-style racial discrimination and Nhambu’s discovery that she must learn to be a Black American. She graduates from college, thus fulfilling her dream of becoming a teacher, and teaches high school in the inner city. She marries, has two children, and establishes herself in the American way of life. Then a visit to Africa, and especially to Tanzania, reawakens the drumbeats and dancing that she carries in her soul. On her return home, she teaches Swahili and African Studies, performs African dance at schools, and creates Aerobics With Soul®, a fitness workout based on African dance. She both finds and creates the family she longed for as a child and connects with her unknown background. The first book of the trilogy, Africa’s Child, was released in 2016. The final book of her memoir series—Drum Beats, Heart Beats—reveals more of Nhambu’s life as she searches for her father.

    It was a sea in name only. It was actually a bone dry, ancient dusty basin pockmarked with craters and littered with rocks and boulders. Somewhere in that 500 mile diameter basin, the astronauts would attempt to make Mankind’s first landing on the Moon. Neil Armstrong would pilot the Lunar Module “Eagle” during its twelve minute descent from orbit down to a landing. Col. Edwin “Buzz” Aldrin would assist him. On the way down they would encounter a host of problems, any one of which could have potentially caused them to have to call off the landing, or, even worse, die making the attempt. The problems were all technical-communications problems, computer problems, guidance problems, sensor problems. Armstrong and Aldrin faced the very real risk of dying by the very same technical sword that they had to live by in order to accomplish the enormous task of landing on the Moon for the first time. Yet the human skills Armstrong and Aldrin employed would be more than equal to the task. Armstrong’s formidable skills as an aviator, honed from the time he was a young boy, would serve him well as he piloted Eagle down amidst a continuing series of systems problems that might have fatally distracted a lesser aviator. Armstrong’s brilliant piloting was complemented by Aldrin’s equally remarkable discipline and calmness as he stoically provided a running commentary on altitude and descent rate while handling systems problems that threatened the landing. Finally, after a harrowing twelve and a half minutes, Armstrong gently landed Eagle at “Tranquility Base”, a name he had personally chosen to denote the location of the first Moon landing. In “Landing Eagle-Inside the Cockpit During the First Moon Landing”, author Mike Engle gives a minute by minute account of the events that occurred throughout Eagle’s descent and landing on the Moon. Engle, a retired NASA engineer and Mission Control flight controller, uses NASA audio files of actual voice recordings made inside Eagle’s cockpit during landing to give the reader an “inside the cockpit” perspective on the first Moon landing. Engle’s transcripts of these recordings, along with background material on the history and technical details behind the enormous effort to accomplish the first Moon landing, give a new and fascinating insight into the events that occurred on that remarkable day fifty years ago.

    A simple web search picks out a handful of relevant needles from the world's biggest haystack: the billions of pages on the World Wide Web. Uploading a photo to Facebook transmits millions of pieces of information over numerous error-prone network links, yet somehow a perfect copy of the photo arrives intact. Without even knowing it, we use public-key cryptography to transmit secret information like credit card numbers; and we use digital signatures to verify the identity of the websites we visit. How do our computers perform these tasks with such ease? This is the first book to answer that question in language anyone can understand, revealing the extraordinary ideas that power our PCs, laptops, and smartphones. Using vivid examples, John MacCormick explains the fundamental "tricks" behind nine types of computer algorithms, including artificial intelligence (where we learn about the "nearest neighbor trick" and "twenty questions trick"), Google's famous PageRank algorithm (which uses the "random surfer trick"), data compression, error correction, and much more. These revolutionary algorithms have changed our world: this book unlocks their secrets, and lays bare the incredible ideas that our computers use every day.

    It is also about Python. However, there is much more. The study of algorithms and data structures is central to understanding what computer science is all about. Learning computer science is not unlike learning any other type of difficult subject matter. The only way to be successful is through deliberate and incremental exposure to the fundamental ideas. A beginning computer scientist needs practice so that there is a thorough understanding before continuing on to the more complex parts of the curriculum. In addition, a beginner needs to be given the opportunity to be successful and gain confidence. This textbook is designed to serve as a text for a first course on data structures and algorithms, typically taught as the second course in the computer science curriculum. Even though the second course is considered more advanced than the first course, this book assumes you are beginners at this level. You may still be struggling with some of the basic ideas and skills from a first computer science course and yet be ready to further explore the discipline and continue to practice problem solving. We cover abstract data types and data structures, writing algorithms, and solving problems. We look at a number of data structures and solve classic problems that arise. The tools and techniques that you learn here will be applied over and over as you continue your study of computer science.

    Now, with the benefit of twenty years' worth of additional knowledge and insight, Stanton Samenow offers a completely updated edition of his classic work, including fresh perceptions into crimes in the spotlight today, from stalking and domestic violence to white-collar crime and political terrorism. Dr. Samenow's three decades of working with criminals have reaffirmed his argument that factors such as poverty, divorce, and media violence do not cause criminality. Rather, as Samenow documents here, all criminals share a particular mind-set--often evident in childhood--that is disturbingly different from that of a responsible citizen. While new types of crime have grown more prevalent, or at least more visible to the public eye--from spousal abuse to school shootings--little has changed in terms of our approach to dealing with crime. Rehabilitation programs based on the assumption that society is more to blame for crime than the criminal, an assumption for which a causal link has yet to be established, have proved to be grossly inadequate. Crime continues to invade every aspect of our lives, criminal court dockets and prisons are oppressively overcrowded and expensive, and recidivism rates continue to escalate.To embark on a truly corrective program, we must begin with the clear understanding that the criminal chooses crime; he chooses to reject society long before society rejects him. The criminal values people only to the extent that he can use them for his own self-serving ends; he does not justify his actions to himself. Only by "habilitating" the criminal, so that he sees himself realistically and develops responsible patterns of thought, can we change his behavior. It is vital that we know who the criminal is and how and why he acts differently from responsible citizens. From that understanding can come reasonable, compassionate, and effective solutions.

    She taught her family how to read Scott’s medical chart and to ask pointed questions, no longer leaving his care to the medical professionals who had overdosed him with drugs to the very brink of death in less than three days.“Jo, you have to tell people what they’ve done to me. You have to tell them!”pleaded her little brother, as he lay writhing in agony.In “For the Love of Scott!”, the author recollects her family’s poignant story of love, bewilderment, and lingering frustration when faced with catastrophic medical mistakes. Read the experiences of Scott Hamilton’s family members as they struggle through a storm of horrific medical errors that could have been prevented and recognize what you need to do when someone you love is faced with life-threatening circumstances created by health experts.It took Jo 27 years to put this heartbreaking event down on paper. Writing opened old wounds and required hours of research and documentation. It forced her family to relive a chapter in their own lives that they desperately wanted closed. Yet, they rallied together to help Jo with her mission to keep that promise.To help further her goals, Jo Hamilton will be donating a portion of the proceeds from the sale of her book, to the 1984 Olympic Gold Medal Winner, Scott Hamilton's foundation, The Scott Hamilton CARES Initiative. The Scott Hamilton CARES Initiative was created to help with cancer research, support cancer patients and their families, and find a cure cancer.

    The text hold students' interest by covering health topics of primary concern to them.
