| star spectra gizmo answers activity b: How Old Is the Universe? David A. Weintraub, 2010-11-15 How a great enigma of astronomy was solved Astronomers have determined that our universe is 13.7 billion years old. How exactly did they come to this precise conclusion? How Old Is the Universe? tells the incredible story of how astronomers solved one of the most compelling mysteries in science and, along the way, introduces readers to fundamental concepts and cutting-edge advances in modern astronomy. The age of our universe poses a deceptively simple question, and its answer carries profound implications for science, religion, and philosophy. David Weintraub traces the centuries-old quest by astronomers to fathom the secrets of the nighttime sky. Describing the achievements of the visionaries whose discoveries collectively unveiled a fundamental mystery, he shows how many independent lines of inquiry and much painstakingly gathered evidence, when fitted together like pieces in a cosmic puzzle, led to the long-sought answer. Astronomers don't believe the universe is 13.7 billion years old—they know it. You will too after reading this book. By focusing on one of the most crucial questions about the universe and challenging readers to understand the answer, Weintraub familiarizes readers with the ideas and phenomena at the heart of modern astronomy, including red giants and white dwarfs, cepheid variable stars and supernovae, clusters of galaxies, gravitational lensing, dark matter, dark energy and the accelerating universe—and much more. Offering a unique historical approach to astronomy, How Old Is the Universe? sheds light on the inner workings of scientific inquiry and reveals how astronomers grapple with deep questions about the physical nature of our universe. |
| star spectra gizmo answers activity b: The Design and Engineering of Curiosity Emily Lakdawalla, 2018-03-27 This book describes the most complex machine ever sent to another planet: Curiosity. It is a one-ton robot with two brains, seventeen cameras, six wheels, nuclear power, and a laser beam on its head. No one human understands how all of its systems and instruments work. This essential reference to the Curiosity mission explains the engineering behind every system on the rover, from its rocket-powered jetpack to its radioisotope thermoelectric generator to its fiendishly complex sample handling system. Its lavishly illustrated text explains how all the instruments work -- its cameras, spectrometers, sample-cooking oven, and weather station -- and describes the instruments' abilities and limitations. It tells you how the systems have functioned on Mars, and how scientists and engineers have worked around problems developed on a faraway planet: holey wheels and broken focus lasers. And it explains the grueling mission operations schedule that keeps the rover working day in and day out. |
| star spectra gizmo answers activity b: Information Arts Stephen Wilson, 2003-02-28 An introduction to the work and ideas of artists who use—and even influence—science and technology. A new breed of contemporary artist engages science and technology—not just to adopt the vocabulary and gizmos, but to explore and comment on the content, agendas, and possibilities. Indeed, proposes Stephen Wilson, the role of the artist is not only to interpret and to spread scientific knowledge, but to be an active partner in determining the direction of research. Years ago, C. P. Snow wrote about the two cultures of science and the humanities; these developments may finally help to change the outlook of those who view science and technology as separate from the general culture. In this rich compendium, Wilson offers the first comprehensive survey of international artists who incorporate concepts and research from mathematics, the physical sciences, biology, kinetics, telecommunications, and experimental digital systems such as artificial intelligence and ubiquitous computing. In addition to visual documentation and statements by the artists, Wilson examines relevant art-theoretical writings and explores emerging scientific and technological research likely to be culturally significant in the future. He also provides lists of resources including organizations, publications, conferences, museums, research centers, and Web sites. |
| star spectra gizmo answers activity b: The Future of Technology Tom Standage, 2005-08-01 From the industrial revolution to the railway age, through the era of electrification, the advent of mass production, and finally to the information age, the same pattern keeps repeating itself. An exciting, vibrant phase of innovation and financial speculation is followed by a crash, after which begins a longer, more stately period during which the technology is actually deployed properly. This collection of surveys and articles from The Economist examines how far technology has come and where it is heading. Part one looks at topics such as the “greying” (maturing) of IT, the growing importance of security, the rise of outsourcing, and the challenge of complexity, all of which have more to do with implementation than innovation. Part two looks at the shift from corporate computing towards consumer technology, whereby new technologies now appear first in consumer gadgets such as mobile phones. Topics covered will include the emergence of the mobile phone as the “digital Swiss Army knife”; the rise of digital cameras, which now outsell film-based ones; the growing size and importance of the games industry and its ever-closer links with other more traditional parts of the entertainment industry; and the social impact of technologies such as text messaging, Wi-Fi, and camera phones. Part three considers which technology will lead the next great phase of technological disruption and focuses on biotechnology, energy technology, and nanotechnology. |
| star spectra gizmo answers activity b: Makers Chris Anderson, 2012-10-02 What happens when DIY meets Web 2.0? In Makers, New York Times bestselling author Chris Anderson reveals how entrepreneurs use web principles to create and produce companies with the potential to be global in scope as well as how they use significantly less in the way of financial resources, tooling, and infrastructure required by traditional manufacturing. Anderson's unique perspective is that small manufacturing will be a significant source of future growth; that the days of giant companies like General Motors are in their twilight; that in an age of open source, custom-fabricated, and do-it-yourself product design, the collective potential of a million garage tinkerers will be unleashed on global markets. |

| star spectra gizmo answers activity b: The Nature of Technology Michael P. Clough, Joanne K. Olson, Dale S Niederhauser, 2013-09-03 How does technology alter thinking and action without our awareness? How can instantaneous information access impede understanding and wisdom? How does technology alter conceptions of education, schooling, teaching and what learning entails? What are the implications of these and other technology issues for society? Meaningful technology education is far more than learning how to use technology. It entails an understanding of the nature of technology — what technology is, how and why technology is developed, how individuals and society direct, react to, and are sometimes unwittingly changed by technology. This book places these and other issues regarding the nature of technology in the context of learning, teaching and schooling. The nature of technology and its impact on education must become a significant object of inquiry among educators. Students must come to understand the nature of technology so that they can make informed decisions regarding how technology may influence thinking, values and action, and when and how technology should be used in their personal lives and in society. Prudent choices regarding technology cannot be made without understanding the issues that this book raises. This book is intended to raise such issues and stimulate thinking and action among teachers, teacher educators, and education researchers. The contributions to this book raise historical and philosophical issues regarding the nature of technology and their implications for education; challenge teacher educators and teachers to promote understanding of the nature of technology; and provide practical considerations for teaching the nature of technology. |

| star spectra gizmo answers activity b: Maelstrom Peter Watts, 2001-10-19 An enormous tidal wave on the west coast of North America has just killed thousands. Lenie Clarke, in a black wetsuit, walks out of the ocean onto a Pacific Northwest beach filled with the oppressed and drugged homeless of the Asian world who have gotten only this far in their attempt to reach America. Is she a monster, or a goddess? One thing is for sure: all hell is breaking loose. This dark, fast-paced, hard SF novel returns to the story begun in Starfish: all human life is threatened by a disease (actually a primeval form of life) from the distant prehuman past. It survived only in the deep ocean rift where Clarke and her companions were stationed before the corporation that employed them tried to sterilize the threat with a secret underwater nuclear strike. But Clarke was far enough away that she was able to survive and tough enough to walk home, 300 miles across the ocean floor. She arrives carrying with her the potential death of the human race, and possessed by a desire for revenge. Maelstrom is a terrifying explosion of cyberpunk noir by a writer whose narrative, says Robert Sheckley, drives like a futuristic locomotive. |

| star spectra gizmo answers activity b: The Business of Electronics A. Kumar Sethi, 2013-11-19 Electronics is an ever-changing field with an entrepreneurial spirit and a rich history, populated by some of the world's most famous companies and personalities. The Business of Electronics details the field's complex ecosystem in all its trials and tribulations. It looks at companies such as Apple, IBM, Samsung, and Nokia, as well as now-extinct companies such as Honeywell Bull (France) and Sinclair Computers (UK) that contributed to technology and business. Sethi shows us how a handful of US companies led the charge in designing equipment that could make millions of small, reliable components; how Nokia started in the timber business; the history of inventors like J.C. Bose, a pioneer in radio communication (who inadvertently made Guglielmo Marconi famous); and why there are numerous companies and creators that never made it or that we have never heard of. This all-encompassing book not only explores the vibrant history of electronics, it uses case studies to examine the companies and people that made history and explain how we ended up where we are today. |

| star spectra gizmo answers activity b: Gilbert Simondon and the Philosophy of the Transindividual Muriel Combes, 2012-10-12 An accessible yet rigorous introduction to the influential French philosopher Gilbert Simondon's philosophy of individuation. Gilbert Simondon (1924–1989), one of the most influential contemporary French philosophers, published only three works: L'individu et sa genèse physico-biologique (The individual and its physico-biological genesis, 1964) and L'individuation psychique et collective (Psychic and collective individuation, 1989), both drawn from his doctoral thesis, and Du mode d'existence des objets techniques (On the mode of existence of technical objects, 1958). It is this last work that brought Simondon into the public eye; as a consequence, he has been considered a “thinker of technics” and cited often in pedagogical reports on teaching technology. Yet Simondon was a philosopher whose ambitions lay in an in-depth renewal of ontology as a process of individuation—that is, how individuals come into being, persist, and transform. In this accessible yet rigorous introduction to Simondon's work, Muriel Combes helps to bridge the gap between Simondon's account of technics and his philosophy of individuation. Some thinkers have found inspiration in Simondon's philosophy of individuation, notably Gilles Deleuze and Félix Guattari. Combes's account, first published in French in 1999, is one of the only studies of Simondon to appear in English. Combes breaks new ground, exploring an ethics and politics adequate to Simondon's hypothesis of preindividual being, considering through the lens of transindividual philosophy what form a nonservile relation to technology might take today. Her book is essential reading for anyone who wants to understand Simondon's work. |

| star spectra gizmo answers activity b: Extreme Stars James B. Kaler, 2001-03-22 Over the past 200 years, our knowledge of stars has expanded enormously. From seeing myriad dots of different brightnesses, we moved on to measure distances, temperatures, sizes, chemical compositions, even ages, finding stars that dwarf our Sun and are dwarfed by it, some in their youth, others ancient. First published in 2001, Extreme Stars describes the lives of stars from a fascinating perspective. It examines their amazing extremes and results in an engaging overview of stellar evolution, suitable for anyone interested in viewing or studying stars. Ten chapters, generously illustrated throughout, explain the natures of the brightest, the largest, the hottest, the youngest, and so on, ending with a selection of the strangest stars the Universe has to offer. Taken as a whole, the chapters show how stars develop and die and how each extreme turns into another under the inexorable twin forces of time and gravity. |
| star spectra gizmo answers activity b: Henry Norris Russell David H. DeVorkin, 2000 Henry Norris Russell lived in two universes: that of his Presbyterian forebears and that of his science. Sharp-witted and animated by nervous energy, he became one of the most powerful voices in twentieth-century American astronomy, wielding that influence in calculated ways to redefine an entire science. He, more than any American of his generation, worked to turn an observation-centered discipline into a theory-driven pursuit centered on physics. Today, professional and amateur astronomers alike know Russell for the Hertzsprung-Russell diagram, the playing field for much of stellar astrophysics, as well as for his work on the evolution of stars and the origin of the solar system. But of far greater importance than his own research, which was truly remarkable in its own right, is Russell's stamp on the field as a whole. Functioning as a headquarters scientist--some called him General--Russell was an astronomer without a telescope. Yet he marshaled the data of the Hales and the Pickerings of the world, injected theory into mainstream astronomy, and brought atomic physics to its very core, often sparking controversy along the way. His students at Princeton went on to populate the most prestigious astronomical institutions in the United States, bringing with them Russell's beliefs that astronomy is really astrophysics and that researchers should be theoretically as well as empirically minded. This first-ever book-length biography of the Dean of American Astronomers interweaves personal and scientific history to illuminate how Russell's privileged Presbyterian family background, his education at Princeton and Cambridge, and his personal inclinations and attachments both served and were at odds with his campaign to modernize astronomy. This book will be of interest not only to astronomers and historians (particularly those interested in the emergence of astrophysics), but to anyone interested in the process of disciplinary change. |

| star spectra gizmo answers activity b: The Sun The Open The Open Courses Library, 2019-10-16 The Sun A Nuclear Powerhouse The Sun puts out an incomprehensible amount of energy--so much that its ultraviolet radiation can cause sunburns from 93 million miles away. It is also very old. As you learned earlier, evidence shows that the Sun formed about 4.5 billion years ago and has been shining ever since. How can the Sun produce so much energy for so long? The Sun's energy output is about 4 × 1026 watts. This is unimaginably bright: brighter than a trillion cities together each with a trillion 100-watt light bulbs. Most known methods of generating energy fall far short of the capacity of the Sun. The total amount of energy produced over the entire life of the Sun is staggering, since the Sun has been shining for billions of years. Scientists were unable to explain the seemingly unlimited energy of stars like the Sun prior to the twentieth century. Chapter Outline: Thinking Ahead Sources of Sunshine: Thermal and Gravitational Energy Mass, Energy, and the Theory of Relativity The Solar Interior: Theory The Solar Interior: Observations The Open Courses Library introduces you to the best Open Source Courses. |
