Book Description
Foreword by Dr. Roger D. Launius, Former NASA Chief Historian For the past 75 years, the U.S. government has invested significant time and money into advanced aerospace research, as evidenced by its many experimental X-plane aircraft and rockets. NASA's X-Planes asks a simple question: What have we gained from it all? To answer this question, the authors provide a comprehensive overview of the X-plane’s long history, from the 1946 X-1 to the modern X-60. The chapters describe not just the technological evolution of these models, but also the wider story of politics, federal budgets, and inter-agency rivalries surrounding them. The book is organized into two sections, with the first covering the operational X-planes that symbolized the Cold War struggle between the U.S. and the U.S.S.R, and the second section surveying post-Cold War aircraft and spacecraft. Featuring dozens of original illustrations of X-plane cross-sections, in-flight profiles, close-ups, and more, this book will educate general readers and specialists alike.

Book Description
When your business is a "job in disguise" and feels like a hamster wheel it's time to get smarter. How to have financial security, freedom and fulfilment ... without being so stupidly busy. When people find out you run your own business you know what they'll ask: "How's it going? Are you busy?" Somehow, "busy" has come to mean "successful." But you didn't wake up this morning thinking "my main aim today is to be as busy as possible!" You don't have your business "to be busy" ... so why DO you work so hard? We all have our businesses for the same reason. The same three reasons actually - to have financial security, freedom and fulfilment - the 3Fs. But these aren't the outcomes for most small businesses. Instead, the common experience feels like you're on a hamster wheel, where the hours are long and the rewards mediocre. Self-esteem is threatened and life, love and relationships impacted. This book explains why this happens and how to approach work in a smarter way, to have a better business with less busyness and more certain results, so you can get back to living and loving life again. How, by climbing off the hamster wheel and escaping The Busyness Delusion, you can take the easier, more certain route to turn your own business into one that does give you all 3Fs. It covers: Why the hustle method is seductive but flawed, and how to use a smarter approach Why most self-employed people unwittingly choose the hardest way to earn, and what the easier options are. How to overcome the biggest obstacle to a smarter business and better life. What financial security really means and how to achieve it quicker and more easily. How to get better results by applying a simple model of how the brain works to give you more control. How to eliminate your competition to make it easier to get better results. Providing a new framework, illustrated in clear diagrams and told through a compelling story, this book reveals why copying others creates the hamster wheel effect, and precisely what to do to have a business and life you deserve. "This book nails the problem with most small businesses. The solutions are time-tested principles, for the first time pulled together in an original and enjoyable way that's easy to understand and implement." Dan Sager

Book Description
"It's not surprising that sooner or later I'd dive down the proverbial rabbit hole into the world of vintage bass guitars."—Geddy Lee From Rush frontman Geddy Lee's personal collection of vintage electric bass guitars, dating from the 1950s to the 1980s, comes the definitive volume on the subject. Geddy's love of the bass has been nurtured over a lifetime spent in the limelight as one of the world's premier rock bassists. For the past seven years, he's dedicated himself to studying the history of the instrument that's been so essential to his career, collecting hundreds of basses from around the globe. Written with arts journalist Daniel Richler, gorgeously photographed in breathtaking detail by Richard Sibbald, and with insight from Geddy’s trusted bass tech and curator, John "Skully" McIntosh, Geddy Lee’s Big Beautiful Book of Bass profiles over 250 classic basses from Geddy’s extensive collection. Representing every tone in the bass palette, every nuance of the rock and roll genre as well as blues, jazz, pop, and country, this one-of-a-kind collection features so-called "beauty queens"—pristine instruments never lifted from their cases—as well as "road warriors"—well-worn, sweat-soaked basses that proudly show their age and use. Complete with personal commentary from Geddy that showcases his knowledge both as a musician and an aficionado, this luxuriously produced volume is a revelatory look at the heavy hitters in the world of bass—Fender, Gibson/Epiphone, Rickenbacker, Höfner, Ampeg—and lesser known but influential global luthiers such as Antonio Wandr Pioli, Dan Armstrong, and Tony Zemaitis. The book also features interviews with John Paul Jones (Led Zeppelin); Adam Clayton (U2); Robert Trujillo (Metallica); Jeff Tweedy (Wilco); Bill Wyman (The Rolling Stones); Les Claypool (Primus); Bob Daisley (Rainbow); Fender expert and owner of the legendary Gibson Explorer, Bass Ken Collins; veteran guitar tech for The Who, Alan Rogan; plus comments from many other great players across three decades of rock and roll. Written in Geddy's singular voice, this book reveals the stories, songs, and history behind the instruments of his inimitable collection. Complete with an index and a graphically designed timeline of the history of the bass, as well as an up-close look at Geddy's basses on Rush's final R40 Tour, his stage and recording gear from 1968 to 2017, and forewords by author and respected vintage expert, Terry Foster, and Rush band member, Alex Lifeson, Geddy Lee's Big Beautiful Book of Bass is the ultimate compendium for the consummate collector, musician, Rush fan, and anyone who loves the bass guitar.

Book Description
The $3x+1$ problem, or Collatz problem, concerns the following seemingly innocent arithmetic procedure applied to integers: If an integer $x$ is odd then “multiply by three and add one”, while if it is even then “divide by two”. The $3x+1$ problem asks whether, starting from any positive integer, repeating this procedure over and over will eventually reach the number 1. Despite its simple appearance, this problem is unsolved. Generalizations of the problem are known to be undecidable, and the problem itself is believed to be extraordinarily difficult. This book reports on what is known on this problem. It consists of a collection of papers, which can be read independently of each other. The book begins with two introductory papers, one giving an overview and current status, and the second giving history and basic results on the problem. These are followed by three survey papers on the problem, relating it to number theory and dynamical systems, to Markov chains and ergodic theory, and to logic and the theory of computation. The next paper presents results on probabilistic models for behavior of the iteration. This is followed by a paper giving the latest computational results on the problem, which verify its truth for $x < 5.4 cdot 10^{18}$. The book also reprints six early papers on the problem and related questions, by L. Collatz, J. H. Conway, H. S. M. Coxeter, C. J. Everett, and R. K. Guy, each with editorial commentary. The book concludes with an annotated bibliography of work on the problem up to the year 2000.

Book Description
As an introductory work, this book contains the elementary materials in map theory, includingembeddings of a graph, abstract maps, duality, orientable and non-orientable maps, isomorphisms of maps and the enumeration of rooted or unrooted maps, particularly, thejoint tree representation of an embedding of a graph on two dimensional manifolds, whichenables one to make the complication much simpler on map enumeration. All of theseare valuable for researchers and students in combinatorics, graphs and low dimensionaltopology.A Smarandache system (Sigma;R) is such a mathematical system with at leastone Smarandachely denied rule r in R such that it behaves in at least two different wayswithin the same set Sigma, i.e., validated and invalided, or only invalided but in multiple distinctways. A map is a 2-cell decomposition of surface, which can be seen as a connectedgraphs in development from partition to permutation, also a basis for constructing Smarandachesystems, particularly, Smarandache 2-manifolds for Smarandache geometries.

Book Description
Upon Ramanujans death in 1920, G. H. Hardy strongly urged that Ramanujans notebooks be published and edited. In 1957, the Tata Institute of Fundamental Research in Bombay finally published a photostat edition of the notebooks, but no editing was undertaken. In 1977, Berndt began the task of editing Ramanujans notebooks: proofs are provided to theorems not yet proven in previous literature, and many results are so startling as to be unique.
