"Karel R Tuesday" is an introduction to computer programming for novices. It uses the Ruby programming language to introduce the principles of dynamic object-oriented programming. It is the latest version in the "Karel The Robot" series, originally developed by Richard Pattis. It is a true successor to the original, emphasizing problem solving in a simple but "Turing Complete" and interesting virtual world. "Karel R Tuesday" stresses problem solving rather than language syntax. It has been shown to be an effective learning environment for novice programmers. A student able to do the exercises in this book, or one of its companions, is truly on his or her way to a deep understanding of programming. Learn to write sophisticated Ruby code in a few weeks. It is not a comprehensive treatment of Ruby, but emphasizes problem solving using objects, writing classes, and developing skill in algorithmic and polymorphic thinking. It goes beyond thinking of computing as just "if" and "while." The advantages pointed out by reviewers of the earlier "Karel J Robot" apply to this version as well: "Karel J Robot" is an excellent introduction to modern computer science, without letting students get overwhelmed by the details of a programming language (even though it is real Java). KJR provides a framework for understanding Object-Oriented Programming from the very beginning. Students are encouraged to develop problem-solving skills by producing projects that solve very complex problems with a relatively small set of tools. Don Slater, Carnegie-Mellon University I have been successfully introducing students in grades 9 through 12 to programming using Karel for the past twenty years and "Karel J Robot" is the most effective version yet. Students love it They find principles of OOP (class design, constructors, methods, inheritance, polymorphism) come naturally to them, even before they learn about control structures. They discover recursive solutions without ever being taught recursion. Best of all, Karel is gender neutral --- both girls and boys are so involved and excited that I have to push them out the door and on to their next class when the period ends. Kathy Larson, Kingston High School, Kingston New York "Karel J Robot: A Gentle Introduction to the Art of Object-Oriented Programming in Java" takes you on a well-sequenced and thoughtful journey through the essential concepts in a first semester computer science course. Experience computer science at the level that it is most inspiring - the conceptual level. The visual environment will help you teach and your students learn because everyone will have immediate visual feedback, enabling them to see what they are doing. You will leave the Karel world with a deep understanding of polymorphism, inheritance, abstraction, modularization, and step-wise refinement, to name just a few topics. If you are an AP Computer Science teacher, you have just found the perfect guide to help ensure you do not lose sight of the forest (i.e., computer science) through the trees (i.e., the details of the language). Dave Wittry, Troy High School "Karel J Robot" provides an uncluttered setting for laying the foundation for all of the key OO concepts. The perfect "starter" for understanding objects, OO design and OO programming. Michael Goldweber, Xavier University

And although originally written in Czech, the book was commissioned by Catbird Press and was therefore written with foreign readers in mind; in other words, no prior knowledge of Capek's writings or his milieu is required."--BOOK JACKET.

Beyond Karel J Robot trades comprehensive coverage of Java low level detail for an understanding of how a language like Java is used to build real programs. It's organization is not that of a reference work, but an enfolding of interesting and necessary concepts used by real programmers. A number of users have asked for more material in the spirit of Karel J Robot. The original book is intended for only the beginning weeks of a course, which leaves some the dilemma of what to do for the rest of the term. This volume is an attempt to discuss some additional ideas as well as some more Java features. The chapter numbering begins where Karel J Robot leaves off and we will frequently make mention of what was learned there. However, we begin to leave the robot world here and will discuss many ideas from beyond that world. The two volumes together should form the basis of a first course in computing using Java. While I have generally followed the guidelines of the College Board recommendations for the APCS AB advanced placement course, I have not attempted to be encyclopedic. We will see int, double, char, etc., but no attempt was made to provide all the rules and caveats of such things. Many books that call themselves text-books seem to me to be, instead, reference works, with everything gathered together nicely to ease looking up information, rather than books to learn from. Instead, I have attempted to show, for the most part, how the features of Java are used to build real programs. This is a book about writing programs, including some quite interesting and difficult programs. You may struggle with some of this material, but the struggle will take you to a better place. I hope you agree that it is worth the work you will put in to it.

DIV“The General Zapped an Angel was written for fun, and offers me a chance to smile at the absurdity of human existence. Therefore, these stories of fantasy and science fiction are among the most serious writing I have done.” —Howard Fast/div DIVNearly forty years after the publication of his first story, “The Wrath of Purple,” in the science fiction magazine Amazing Stories, Howard Fast returned to the genre with a set of nine supremely entertaining tales. In this collection, a Vietnam general shoots down what appears to be an angel, a man sells his soul to the devil for a copy of the next day’s Wall Street Journal, and a group of alien beings bestow a mouse with human thought and emotion. Fast, one of the bestselling authors of the twentieth century, skewers war hawks, oil speculators, and profit-at-all-costs capitalism, issues that are still relevant today./divDIV /divDIVThis ebook features an illustrated biography of Howard Fast including rare photos from the author’s estate./div

In recent years, the importance of material science, or the understanding of the physical properties of food materials in the progress of food engineering, has become more recognized. Increasing numbers of basic and applied studies in this area appear in numerous journals and literature scattered around various disciplines. This 'Series in Food Material Science' is planned to survey, collect, organize, review and evaluate these studies. By doing so, it is hoped that this series will be instrumental in bringing about a better understanding of the physical properties of food materials, better communication among scientists, and rapid progress in food engineering, science and technology. This volume, Theory, Determination and Control of Physical Properties of Food Materia/s, Volume I of the 'Series in Food Material Science', contains basic principles, methods and instrumental methods for determination and application of the modifi cation of physical properties. In this book, noted investigators in the subjects have pooled their knowledge and made it available in a condensed form. Every chapter is selfcontained with most of them starting with a review or introduction, including the viewpoint of the author. These should offer a beginner a very general introduction to the subjects covered, make the scientists and technologists in the field aware of current progress and allow the specialists a chance to compare different viewpoints.
