Challenger Revealed by Richard C. Cook Pdf

The Reagan Administration pushed hard for NASA to launch shuttle mission 51L, before it was ready. 73 seconds into the launch, the shuttle exploded, killing seven and leaving a nation traumatized. Richard Cook, lead resource analyst at NASA for the Solid Rocket Boosters, was the first to warn of possible catastrophic failure. His memo, detailing astronaut concerns and warnings from the shuttle builders at Morton Thiokol, was ignored by top NASA officials and members of the Reagan administration. In the aftermath, NASA launched an investigation to "discover" the cause of the disaster. Though within NASA there was absolute certainty about the O-ring failure, they began a cover-up by publicly proclaiming that the cause was unknown. A Reagan administration Commission perpetrated the same lie. When Cook realized that the Commission was not interested in the truth, he leaked the original documents to the New York Times, setting off a cascade of disclosures, including revelations by Morton Thiokol engineers that they had tried to stop the launch.--From publisher description.

Report on the Radiolaria Collected by H.M.S. Challenger During the Years 1873-1876: Porulosa (Spumellaria and Acantharia) and Subclass Osculosa by Ernst Heinrich Philipp August Haeckel Pdf

ÊThe significance of the Radiolaria in regard to the relations of life in the ocean has been increased in a most unexpected manner by the discoveries of the Challenger. Large swarms of these delicate Rhizopoda were found not only at the surface of the open ocean but also in its different bathymetrical zones. Thousands of new species make up the wonderful Radiolarian ooze, which covers large areas of the deep-sea bed, and was brought up from abysses of from 2000 to 4000 fathoms by the sounding machine of the Challenger. They open a new world to morphological investigation. When ten years ago (in the autumn of 1876) I accepted the enticing invitation of Sir Wyville Thomson to undertake the investigation of these microscopic creatures, I hoped to be able to accomplish the task with some degree of completeness within a period of from three to five years, but the further my investigations proceeded the more immeasurable seemed the range of forms, like the boundless firmament of stars. I soon found myself compelled to decide between making a detailed study of a selection of special forms or giving as complete a survey as possible of the varied forms of the whole class; and I decided upon the latter course, having regard both to the general plan of the Challenger Reports, and to the interests of our acquaintance with the class as a whole. I must, however, confess at the close of my work that my original intention is far from having been fulfilled. The extraordinary extent and varied difficulties of the undertaking must excuse the many deficiencies. The special examination of the Challenger collection was for the most part completed in the summer of 1881; I collected its results in my Entwurf eines Radiolarien-Systems auf Grund von Studien der Challenger-Radiolarien (Jenaische Zeitschr. f. Naturw., Bd. xv., 1881). Since the manuscript of this preliminary communication was completed only a few days before my departure for Ceylon, and since I was unable to correct the proofs myself, several errors have crept into the Prodromus Systematis Radiolarium included in it. These have been corrected in the following more extensive working out of it. Even at that time I had distinguished 630 genera and more than 2000 species; but on the revision of these, which I undertook immediately on my return from India, this number was considerably increased. The total number of forms here described amounts to 739 genera and 4318 species; of these 3508 are new, as against 810 previously described. In spite of this large number, however, and in spite of the astonishing variety of the new and marvellous forms, the riches of the Challenger collection are by no means exhausted. A careful and patient worker who would devote a second decade to the work, would probably increase the number of new forms (especially of the smaller ones) by more than a thousand; but for a really complete examination, the lifetime of one man would not suffice.

Rockets and Missiles by A. Bowdoin Van Riper Pdf

Beginning with World War II, missiles transformed the art of war. For the first time, cities of warring nations were vulnerable to sudden, unannounced, long-distance attacks. At the same time, rockets made possible one of the great triumphs of the modern age—the exploration of space. Beginning with the origins of rocketry in medieval and early modern Asia, Rockets and Missiles traces the history of the technology that led to both the great fear of global warfare and the great excitement of the Space Age. This volume focuses on rocketry in late-twentieth-century Western Europe, Russia, and the United States, as well as the spread of rocket technology to East Asia and the Middle East. It covers the full history of rocket technology—including how rockets improved in performance, reliability, and versatility and how they affected everyday life.

Truth, Lies, and O-Rings by Allan J. McDonald Pdf

On a cold January morning in 1986, NASA launched the Space Shuttle Challenger, despite warnings against doing so by many individuals, including Allan McDonald. The fiery destruction of Challenger on live television moments after launch remains an indelible image in the nation’s collective memory. In Truth, Lies, and O-Rings, McDonald, a skilled engineer and executive, relives the tragedy from where he stood at Launch Control Center. As he fought to draw attention to the real reasons behind the disaster, he was the only one targeted for retribution by both NASA and his employer, Morton Thiokol, Inc., makers of the shuttle's solid rocket boosters. In this whistle-blowing yet rigorous and fair-minded book, McDonald, with the assistance of internationally distinguished aerospace historian James R. Hansen, addresses all of the factors that led to the accident, some of which were never included in NASA's Failure Team report submitted to the Presidential Commission. Truth, Lies, and O-Rings is the first look at the Challenger tragedy and its aftermath from someone who was on the inside, recognized the potential disaster, and tried to prevent it. It also addresses the early warnings of very severe debris issues from the first two post-Challenger flights, which ultimately resulted in the loss of Columbia some fifteen years later.

Risk Management by Nerija Banaitiene Pdf

Every business and decision involves a certain amount of risk. Risk might cause a loss to a company. This does not mean, however, that businesses cannot take risks. As disengagement and risk aversion may result in missed business opportunities, which will lead to slower growth and reduced prosperity of a company. In today's increasingly complex and diverse environment, it is crucial to find the right balance between risk aversion and risk taking. To do this it is essential to understand the complex, out of the whole range of economic, technical, operational, environmental and social risks associated with the company's activities. However, risk management is about much more than merely avoiding or successfully deriving benefit from opportunities. Risk management is the identification, assessment, and prioritization of risks. Lastly, risk management helps a company to handle the risks associated with a rapidly changing business environment.

The Challenger Sale by Matthew Dixon,Brent Adamson Pdf

What's the secret to sales success? If you're like most business leaders, you'd say it's fundamentally about relationships-and you'd be wrong. The best salespeople don't just build relationships with customers. They challenge them. The need to understand what top-performing reps are doing that their average performing colleagues are not drove Matthew Dixon, Brent Adamson, and their colleagues at Corporate Executive Board to investigate the skills, behaviors, knowledge, and attitudes that matter most for high performance. And what they discovered may be the biggest shock to conventional sales wisdom in decades. Based on an exhaustive study of thousands of sales reps across multiple industries and geographies, The Challenger Sale argues that classic relationship building is a losing approach, especially when it comes to selling complex, large-scale business-to-business solutions. The authors' study found that every sales rep in the world falls into one of five distinct profiles, and while all of these types of reps can deliver average sales performance, only one-the Challenger- delivers consistently high performance. Instead of bludgeoning customers with endless facts and features about their company and products, Challengers approach customers with unique insights about how they can save or make money. They tailor their sales message to the customer's specific needs and objectives. Rather than acquiescing to the customer's every demand or objection, they are assertive, pushing back when necessary and taking control of the sale. The things that make Challengers unique are replicable and teachable to the average sales rep. Once you understand how to identify the Challengers in your organization, you can model their approach and embed it throughout your sales force. The authors explain how almost any average-performing rep, once equipped with the right tools, can successfully reframe customers' expectations and deliver a distinctive purchase experience that drives higher levels of customer loyalty and, ultimately, greater growth.

The Hundred-Year Marathon by Michael Pillsbury Pdf

One of the U.S. government's leading China experts reveals the hidden strategy fueling that country's rise – and how Americans have been seduced into helping China overtake us as the world's leading superpower. For more than forty years, the United States has played an indispensable role helping the Chinese government build a booming economy, develop its scientific and military capabilities, and take its place on the world stage, in the belief that China's rise will bring us cooperation, diplomacy, and free trade. But what if the "China Dream" is to replace us, just as America replaced the British Empire, without firing a shot? Based on interviews with Chinese defectors and newly declassified, previously undisclosed national security documents, The Hundred-Year Marathon reveals China's secret strategy to supplant the United States as the world's dominant power, and to do so by 2049, the one-hundredth anniversary of the founding of the People's Republic. Michael Pillsbury, a fluent Mandarin speaker who has served in senior national security positions in the U.S. government since the days of Richard Nixon and Henry Kissinger, draws on his decades of contact with the "hawks" in China's military and intelligence agencies and translates their documents, speeches, and books to show how the teachings of traditional Chinese statecraft underpin their actions. He offers an inside look at how the Chinese really view America and its leaders – as barbarians who will be the architects of their own demise. Pillsbury also explains how the U.S. government has helped – sometimes unwittingly and sometimes deliberately – to make this "China Dream" come true, and he calls for the United States to implement a new, more competitive strategy toward China as it really is, and not as we might wish it to be. The Hundred-Year Marathon is a wake-up call as we face the greatest national security challenge of the twenty-first century.

Game-Theoretic Models of the Political Influence of Interest Groups by Randolph Sloof Pdf

In this chapter the topic of this book is introduced. Section 1. 1 provides a brief and rather general motivation for the scientific project undertaken here. Interest groups are a very popular object of scientific inquiry, and they received already considerable research attention from scholars in political science, as well as from researchers in economics. Necessarily, then, this book adds to a literature which is already quite developed. A detailed positioning in this literature of the theoretical material presented in this monograph will be given in Chapter 2. This second chapter will also, by means of a review of the empirical literature, provide a more general overview of the issues deemed to be important when studying the influence of interest groups on public policy. The outline of the entire book is described in greater detail in Section 1. 2. As most issues involved are more easily presented in later chapters, this introductory chapter is kept brief. 1. 1 MOTIVATION Substantial political power is often attributed to interest groups. Examples abound in both the economics and political science literature, as well as in journalistic accounts and popular publications. On many occasions the authors express concerns about the negative impact of interest groups on the democratic quality of government. "The interests of a small group are served at the expense of the interests of the general public, the taxpayers!", is an often heard popular complaint.
