Book Description

More and more businesses and government agencies are finding software and IT to be crucial to their success and efficiency. This increased reliance is surfacing many shortcomings in the way software projects are managed. Software is central to running any business effectively - it's just as important to success as marketing, sales, finance, and operations. This book provides an MBA level of understanding of the key dynamics of software projects and will position executives to improve outcomes. Managing the "Black Hole" is about management, not technology. Software projects are risky - failures are common. Less than 1/3 of all software projects (purchased or built) are fully successful (on-time, on-budget, with all intended features and functions). The average software project overruns its budget by around 50% and schedule by around 80%. The average project delivers less than 70% of planned features and functions. Software projects are extremely wasteful - in an average organization only 30-40% of total software cost results in "value-added" - best in class organizations (less than 15%) achieve twice as much value add - 100% more 'bang for the buck'. This book examines the underlying root causes of failures - the "Seven Deadly Sins" and provides a non-technical introduction to a range of proven remedies - the "Five Redeeming Virtues." The ideas in this book will enable your organization to join the elite few who have taken these lessons to heart. Leaving the solution to these problems solely in the hands of IT specialists has not proven a successful strategy - top management understanding and engagement are required to improve outcomes! "Managing the Black Hole provides a substantive yet refreshingly succinct tour of software project risks and remedies. This book explains the most important software project issues without 'geek-speak', using examples and metaphor readily comprehensible to those without extensive technical backgrounds. Gary has captured just the right level of depth and detail for today's busy executives, both inside and outside IT. Anyone dealing with risky software projects, whether 'buying' or 'building', will benefit from this book." -Tony Salvaggio, CEO, Computer Aid, Inc. About the Author Gary Gack is an MBA from the Wharton School, a Six Sigma Black Belt, and an ASQ-certified software quality engineer. He provides consulting, training and coaching related to business and software/IT process improvement, with emphasis on "best of breed" integration of proven best practices and models. His primary focus and interest is in helping organizations improve business performance by more effective management of the interface between general managers and software and IT. By working on both sides of the "technology divide" he has helped reduce failures, increase productivity and quality, reduce waste, and control risk.

Book Description

From the acclaimed author of Black Hole Blues and Other Songs from Outer Space—an authoritative and accessible guide to the most alluring and challenging phenomena of contemporary science. "[Levin will] take you on a safe black hole trip, an exciting travel story enjoyed from your chair’s event horizon.” —Boston Globe Through her writing, astrophysicist Janna Levin has focused on making the science she studies not just comprehensible but also, and perhaps more important, intriguing to the nonscientist. In this book, she helps us to understand and find delight in the black hole—perhaps the most opaque theoretical construct ever imagined by physicists—illustrated with original artwork by American painter and photographer Lia Halloran. Levin takes us on an evocative exploration of black holes, provoking us to imagine the visceral experience of a black hole encounter. She reveals the influence of black holes as they populate the universe, sculpt galaxies, and even infuse the whole expanse of reality that we inhabit. Lively, engaging, and utterly unique, Black Hole Survival Guide is not just informative—it is, as well, a wonderful read from first to last.

Book Description

Dive into a mind-bending exploration of the physics of black holes Black holes, predicted by Albert Einstein’s general theory of relativity more than a century ago, have long intrigued scientists and the public with their bizarre and fantastical properties. Although Einstein understood that black holes were mathematical solutions to his equations, he never accepted their physical reality—a viewpoint many shared. This all changed in the 1960s and 1970s, when a deeper conceptual understanding of black holes developed just as new observations revealed the existence of quasars and X-ray binary star systems, whose mysterious properties could be explained by the presence of black holes. Black holes have since been the subject of intense research—and the physics governing how they behave and affect their surroundings is stranger and more mind-bending than any fiction. After introducing the basics of the special and general theories of relativity, this book describes black holes both as astrophysical objects and theoretical “laboratories” in which physicists can test their understanding of gravitational, quantum, and thermal physics. From Schwarzschild black holes to rotating and colliding black holes, and from gravitational radiation to Hawking radiation and information loss, Steven Gubser and Frans Pretorius use creative thought experiments and analogies to explain their subject accessibly. They also describe the decades-long quest to observe the universe in gravitational waves, which recently resulted in the LIGO observatories’ detection of the distinctive gravitational wave “chirp” of two colliding black holes—the first direct observation of black holes’ existence. The Little Book of Black Holes takes readers deep into the mysterious heart of the subject, offering rare clarity of insight into the physics that makes black holes simple yet destructive manifestations of geometric destiny.

Book Description

The authoritative story of the headline-making discovery of gravitational waves—by an eminent theoretical astrophysicist and award-winning writer. From the author of How the Universe Got Its Spots and A Madman Dreams of Turing Machines, the epic story of the scientific campaign to record the soundtrack of our universe. Black holes are dark. That is their essence. When black holes collide, they will do so unilluminated. Yet the black hole collision is an event more powerful than any since the origin of the universe. The profusion of energy will emanate as waves in the shape of spacetime: gravitational waves. No telescope will ever record the event; instead, the only evidence would be the sound of spacetime ringing. In 1916, Einstein predicted the existence of gravitational waves, his top priority after he proposed his theory of curved spacetime. One century later, we are recording the first sounds from space, the soundtrack to accompany astronomy’s silent movie. In Black Hole Blues and Other Songs from Outer Space, Janna Levin recounts the fascinating story of the obsessions, the aspirations, and the trials of the scientists who embarked on an arduous, fifty-year endeavor to capture these elusive waves. An experimental ambition that began as an amusing thought experiment, a mad idea, became the object of fixation for the original architects—Rai Weiss, Kip Thorne, and Ron Drever. Striving to make the ambition a reality, the original three gradually accumulated an international team of hundreds. As this book was written, two massive instruments of remarkably delicate sensitivity were brought to advanced capability. As the book draws to a close, five decades after the experimental ambition began, the team races to intercept a wisp of a sound with two colossal machines, hoping to succeed in time for the centenary of Einstein’s most radical idea. Janna Levin’s absorbing account of the surprises, disappointments, achievements, and risks in this unfolding story offers a portrait of modern science that is unlike anything we’ve seen before.

Book Description

A girl's friendship with a lonely black hole leads her to face her own sadness in this original, funny, and touching middle grade novel for fans of Crenshaw and Flora & Ulysses. When eleven-year-old Stella Rodriguez shows up at NASA to request that her recording be included in Carl Sagan's Golden Record, something unexpected happens: A black hole follows her home, and sets out to live in her house as a pet. The black hole swallows everything he touches, which is challenging to say the least—but also turns out to be a convenient way to get rid of those items that Stella doesn't want around. Soon the ugly sweaters her aunt has made for her all disappear within the black hole, as does the smelly class hamster she's taking care of, and most important, all the reminders of her dead father that are just too painful to have around. It's not until Stella, her younger brother, Cosmo, the family puppy, and even the bathroom tub all get swallowed up by the black hole that Stella comes to realize she has been letting her own grief consume her. And that's not the only thing she realizes as she attempts to get back home. This is an astonishingly original and funny adventure with a great big heart.
