This book translates "thinking like a rocket scientist" into every day thinking so it can be used by anyone. It’s short and snappy and written by a rocket scientist. The book illustrates the methods (the 7 secrets) with anecdotes, quotations and biographical sketches of famous scientists, personal stories and insights, and occasionally some space history. The author reveals that rocket science is just common sense applied to the extraordinarily uncommon environment of outer space and that rocket scientists are people, too. It is intended for "armchair" scientists, and for those interested in popular psychology, space history, and science fiction films.
In this book, a scientist and dedicated film enthusiast discusses the portrayal of science in more than one hundred films, including science fiction, scientific biographies, and documentaries. Beginning with early films like Voyage to the Moon and Metropolis and concluding with more recent offerings like The Matrix, War of the Worlds, A Beautiful Mind, and An Inconvenient Truth, Sidney Perkowitz questions how much faith we can put into Hollywood's depiction of scientists and their work, how accurately these films capture scientific fact and theory, whether cataclysms like our collision with a comet can actually happen, and to what extent these films influence public opinion about science and the future. Bringing together history, scientific theory, and humorous observation, Hollywood Science features dozens of film stills and a list of the all-time best and worst science-fiction movies.
“A breath of intellectual fresh air . . . [an] amusing look at how to dispel endemic pseudoscience and conspiracy theories through rational thinking.” —Publishers Weekly Aliens. Ley lines. Water dowsing. Conspiracies and myths captivate imaginations and promise mystery and magic. Whether it’s arguing about the moon landing hoax or a Frisbee-like Earth drifting through space, when held up to science and critical thinking, these ideas fall flat. In Weird Earth: Debunking Strange Ideas About Our Planet, Donald R. Prothero demystifies these conspiracies and offers answers to some of humanity’s most outlandish questions. Applying his extensive scientific knowledge, Prothero corrects misinformation that con artists and quacks use to hoodwink others about geology—hollow earth, expanding earth, and bizarre earthquakes—and mystical and paranormal happenings—healing crystals, alien landings, and the gates of hell. By deconstructing wild claims such as prophesies of imminent natural disasters, Prothero provides a way for everyone to recognize dubious assertions. Prothero answers these claims with facts, offering historical and scientific context in a light-hearted manner that is accessible to everyone, no matter their background. With a careful layering of evidence in geology, archaeology, and biblical and historical records, Prothero’s Weird Earth examines each conspiracy and myth and leaves no question unanswered. Weird Earth is about the facts and the people who don’t believe them. Don Prothero describes the process of science—and the process of not accepting it. If you’re wondering if humans walked on the Moon, if you’ve wondered where the lost City of Atlantis went, or if you’re wondering what your cat will do before an earthquake, check out Weird Earth.” —Bill Nye
Want to know not just what makes rockets go up but how to do it optimally? Optimal control theory has become such an important field in aerospace engineering that no graduate student or practicing engineer can afford to be without a working knowledge of it. This is the first book that begins from scratch to teach the reader the basic principles of the calculus of variations, develop the necessary conditions step-by-step, and introduce the elementary computational techniques of optimal control. This book, with problems and an online solution manual, provides the graduate-level reader with enough introductory knowledge so that he or she can not only read the literature and study the next level textbook but can also apply the theory to find optimal solutions in practice. No more is needed than the usual background of an undergraduate engineering, science, or mathematics program: namely calculus, differential equations, and numerical integration. Although finding optimal solutions for these problems is a complex process involving the calculus of variations, the authors carefully lay out step-by-step the most important theorems and concepts. Numerous examples are worked to demonstrate how to apply the theories to everything from classical problems (e.g., crossing a river in minimum time) to engineering problems (e.g., minimum-fuel launch of a satellite). Throughout the book use is made of the time-optimal launch of a satellite into orbit as an important case study with detailed analysis of two examples: launch from the Moon and launch from Earth. For launching into the field of optimal solutions, look no further!
This textbook provides details of the derivation of Lagrange's planetary equations and of the closely related Gauss's variational equations, thereby covering a sorely needed topic in existing literature. Analytical solutions can help verify the results of numerical work, giving one confidence that his or her analysis is correct. The authors—all experienced experts in astrodynamics and space missions—take on the massive derivation problem step by step in order to help readers identify and understand possible analytical solutions in their own endeavors. The stages are elementary yet rigorous; suggested student research project topics are provided. After deriving the variational equations, the authors apply them to many interesting problems, including the Earth-Moon system, the effect of an oblate planet, the perturbation of Mercury's orbit due to General Relativity, and the perturbation due to atmospheric drag. Along the way, they introduce several useful techniques such as averaging, Poincaré's method of small parameters, and variation of parameters. In the end, this textbook will help students, practicing engineers, and professionals across the fields of astrodynamics, astronomy, dynamics, physics, planetary science, spacecraft missions, and others. “An extensive, detailed, yet still easy-to-follow presentation of the field of orbital perturbations.” - Prof. Hanspeter Schaub, Smead Aerospace Engineering Sciences Department, University of Colorado, Boulder “This book, based on decades of teaching experience, is an invaluable resource for aerospace engineering students and practitioners alike who need an in-depth understanding of the equations they use.” - Dr. Jean Albert Kéchichian, The Aerospace Corporation, Retired “Today we look at perturbations through the lens of the modern computer. But knowing the why and the how is equally important. In this well organized and thorough compendium of equations and derivations, the authors bring some of the relevant gems from the past back into the contemporary literature.” - Dr. David A Vallado, Senior Research Astrodynamicist, COMSPOC “The book presentation is with the thoroughness that one always sees with these authors. Their theoretical development is followed with a set of Earth orbiting and Solar System examples demonstrating the application of Lagrange’s planetary equations for systems with both conservative and nonconservative forces, some of which are not seen in orbital mechanics books.” - Prof. Kyle T. Alfriend, University Distinguished Professor, Texas A&M University

Enduring Issues in Special Education is aimed at any course in the undergraduate or graduate special education curriculum that is wholly or partly devoted to a critical examination of current issues in special education. The book organizes 28 chapters into seven sections using familiar structuring principles—what, who, where, how, when, why, and whither. Each section begins with an introduction that provides historical, legal, and theoretical background information and organizing commentary for the chapters that follow. The book’s objective, in addition to informing readers about the issues, is to develop critical thinking skills in the context of special education. Key features include the following: Dialectic Format – Each of the 28 chapters presents compelling reasons for addressing the issue at hand and specific ways to do so. Because each issue is written from different perspectives and focuses on a variety of aspects, readers are encouraged to weigh the arguments, seek additional information, and come up with synthesized positions of their own. Organizing Framework – The book’s seven sections have been arranged according to a scheme that is the essence of most investigative reporting and provides a coherent, easy-to-understand framework for readers. Expertise – All chapters are written by leading scholars who are highly regarded experts in their fields and conclude with suggested readings and discussion questions for additional study.
