    It will introduce a new way of looking not only at the treatment of circuits, but also at the treatment of introductory coursework in engineering in general. Using the concept of ''abstraction, '' the book attempts to form a bridge between the world of physics and the world of large computer systems. In particular, it attempts to unify electrical engineering and computer science as the art of creating and exploiting successive abstractions to manage the complexity of building useful electrical systems. Computer systems are simply one type of electrical systems

    Vaughn Vernon couples guided approaches to implementation with modern architectures, highlighting the importance and value of focusing on the business domain while balancing technical considerations.Building on Eric Evans’ seminal book, Domain-Driven Design, the author presents practical DDD techniques through examples from familiar domains. Each principle is backed up by realistic Java examples–all applicable to C# developers–and all content is tied together by a single case study: the delivery of a large-scale Scrum-based SaaS system for a multitenant environment.The author takes you far beyond “DDD-lite” approaches that embrace DDD solely as a technical toolset, and shows you how to fully leverage DDD’s “strategic design patterns” using Bounded Context, Context Maps, and the Ubiquitous Language. Using these techniques and examples, you can reduce time to market and improve quality, as you build software that is more flexible, more scalable, and more tightly aligned to business goals.

    Despite its title, it's not wild ranting pseudo-science to be dismissed by those with brains. Rather, Amdahl maintains that one need not understand quantum physics to grasp how electricity works in practical applications. To understand your toaster or your fax machine, it doesn't really matter whether there are electrons or not, and it's a lot easier and more fun to start with the toaster than with quarks and calculus. The book is mildly weird, often funny, always clear and easy to understand. It assumes the reader doesn't know a volt from a hole in the ground and gently leads him or her through integrated circuits, radio, oscillators and the basics of the digital revolution using examples that include green buffalo, microscopic beer parties, break-dancing chickens and naked Norwegian girls in rowboats. OK, it's more than mildly weird.The book has been reprinted numerous times since 1991 and has achieved minor cult status. Reviewed and praised in dozens of electronics and educational magazines, it is used as a text by major corporations, colleges, high schools, military schools and trade schools. It has been studied by education programs at colleges across the United States. This book was making wise cracks in the corner before anyone thought of designing books for dummies and idiots; some say it helped to inspire that industry.It may be the only "introduction to electronics books" with back cover comments by Dave Barry, Ray Bradbury, Clive Cussler, and George Garrett, as well as recomendations from Robert Hazen, Bob Mostafapour, Dr. Roger Young, Dr. Wayne Green, Scott Rundle, Brian Battles, Michelle Guido, Herb Reichert and Emil Venere. As Monitoring Times said, "Perhaps the best electronics book ever. If you'd like to learn about basic electronics but haven't been able to pull it off, get There Are No Electrons. Just trust us. Get the book."

    But Neil Armstrong and Sally Ride would have never made history, and humankind would not have touched the stars, if not for the men and women on the ground who lit the fuse that launched the first rockets.Enthralled as a boy by the exploits of Flash Gordon and the novels of Robert Heinlein and Arthur C. Clarke—who put the science in science fiction—James French became one of the original unsung engineers of America’s groundbreaking space program. His fascinating memoir offers an up-close-and-technical look at building, testing, and perfecting the pioneering Saturn rockets and original lunar landing module, and he shares true tales, both humorous and harrowing, of life—and near death—on the front lines of scientific exploration.If you’ve ever said, “It’s not rocket science,” you’re right. It’s rocket engineering—and here’s your chance to marvel at how it changed the world and made it possible to explore all that lies beyond Earth. James R French graduated from MIT in 1958 with a degree of BSME Specializing in Propulsion. His first job was with Rocketdyne Division of North American Aviation where he worked on developmental testing of H-1 engines and combustion devices hardware for F-1 and J-2 engines used in Saturn 5. Mr. French has also worked at TRW Systems, where he was Lead Development Test Engineer on the Lunar Module Descent Engine, and Jet Propulsion Laboratory where he was Advanced Planetary studies Manager as well as Chief Engineer for the SP-100 Space Nuclear Power System and worked on Mariners 5, 6, 7, 8, and 9; Viking 1 & 2 and Voyager 1 & 2. . In 1986, he helped found American Rocket Co., a commercial launch company.Since 1987, Mr. French has been consultant to a variety of aerospace companies, SDIO, NASA, and USAF. He has participated in various startup companies in the private space flight arena and currently consults extensively to Blue Origin. Mr. French is co-author with Dr. Michael Griffin of the best-selling text Space Vehicle Design, published by AIAA. The second edition of the book has received the Summerfield Book Award for 2008. Mr. French is a Fellow of both AIAA and the British Interplanetary Society and a 50+ year member of AIAA. He has held several Technical Committee and other posts in AIAA. Cover design by Evan Twohy
