| gizmo star spectra answer key: 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. |

| gizmo star spectra answer key: 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. |
| gizmo star spectra answer key: Cloud Atlas (20th Anniversary Edition) David Mitchell, 2010-07-16 #1 INTERNATIONAL BESTSELLER • A timeless, structure-bending classic that explores how actions of individual lives impact the past, present and future—from a postmodern visionary and one of the leading voices in fiction Featuring a new afterword by David Mitchell and a new introduction by Gabrielle Zevin, author of Tomorrow, and Tomorrow, and Tomorrow One of the New York Times’s 100 Best Books of the 21st Century • Shortlisted for the International Booker Prize Cloud Atlas begins in 1850 with Adam Ewing, an American notary voyaging from the Chatham Isles to his home in California. Ewing is befriended by a physician, Dr. Goose, who begins to treat him for a rare species of brain parasite. The novel careens, with dazzling virtuosity, to Belgium in 1931, to the West Coast in the 1970s, to an inglorious present-day England, to a Korean superstate of the near future where neocapitalism has run amok, and, finally, to a postapocalyptic Iron Age Hawaii in the last days of history. But the story doesn’t end even there. The novel boomerangs back through centuries and space, returning by the same route, in reverse, to its starting point. Along the way, David Mitchell reveals how his disparate characters connect, how their fates intertwine, and how their souls drift across time like clouds across the sky. As wild as a video game, as mysterious as a Zen koan, Cloud Atlas is an unforgettable tour de force that, like its incomparable author, has transcended its cult classic status to become a worldwide phenomenon. |
| gizmo star spectra answer key: The First Stars Volker Bromm, 2016-09-07 The formation of the first stars (Pop III stars) and galaxies is one of the great outstanding challenges in modern astrophysics and cosmology. The first stars are likely key drivers for early cosmic evolution and will be at the center of attention over the next decade. The best available space and ground-based telescopes like the Hubble Space Telescope probe the Universe to high redshifts and provide us with tantalizing hints; but they cannot yet directly detect the first generation of stars and the formation of the first galaxies. This is left as key science for future telecopes like the James Webb Space Telescope. This book is based in part on classroom tested lectures related to Pop III stars, but also draws from the author's review articles of the main physical principles involved. The book will thus combine pedagogical introductory chapters with more advanced ones to survey the cutting-edge advances from the frontier of research. It covers the theory of first star formation, the relation between first stars and dark matter, their impact on cosmology, their observational signatures, the transition to normal star formation as well as the assembly of the first galaxies. It will prepare students for interpreting observational findings and their cosmological implications. |
| gizmo star spectra answer key: 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. |
| gizmo star spectra answer key: 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. |
| gizmo star spectra answer key: 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. |

| gizmo star spectra answer key: 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. |

| gizmo star spectra answer key: Hackers Steven Levy, 2010-05-19 This 25th anniversary edition of Steven Levy's classic book traces the exploits of the computer revolution's original hackers -- those brilliant and eccentric nerds from the late 1950s through the early '80s who took risks, bent the rules, and pushed the world in a radical new direction. With updated material from noteworthy hackers such as Bill Gates, Mark Zuckerberg, Richard Stallman, and Steve Wozniak, Hackers is a fascinating story that begins in early computer research labs and leads to the first home computers. Levy profiles the imaginative brainiacs who found clever and unorthodox solutions to computer engineering problems. They had a shared sense of values, known as the hacker ethic, that still thrives today. Hackers captures a seminal period in recent history when underground activities blazed a trail for today's digital world, from MIT students finagling access to clunky computer-card machines to the DIY culture that spawned the Altair and the Apple II. |

| gizmo star spectra answer key: The Physical Properties of the Groups of Galaxies Lorenzo Lovisari, Stefano Ettori, 2021-08-30 Galaxy groups consist of a few tens of galaxies bound in a common gravitational potential and contain a significant fraction of the overall universal baryon budget. Therefore, they are key to our understanding of how the bulk of matter in the Universe accretes and forms hierarchical structures and how different sources of feedback affect their gravitational collapse. However, despite their crucial role in cosmic structure formation and evolution, galaxy groups have received less attention compared to massive clusters. This is perhaps in part due to their rarity in being observed and properly characterized. With the advent of eROSITA, many thousands of galaxy groups will be detected by X-ray, complementing optical and SZ coverage. In this Special Issue we collected and organized the latest developments in our understanding of these systems and present future prospects from both observational and theoretical points of view. |
| gizmo star spectra answer key: The Sirius Mystery Robert Temple, 1999 The most academically credible case for alien visitation. Is the existance of civilisation on earth the result of contact from inhabitants of a planet in the system of the star Sirius prior to 3000BC? There are tribal cultures in present-day Africa whose most sacred and secret and traditions are based on this theory. Central to their cosmology is a body of knowledge concerning the system of the star Sirius that is astounding it in its accuracy of detail, including specific information only recently accessible to modern science. Robert Temple traces the traditions of the Dogon and three related tribes back 5, 000 years to the ancient Mediterranean cultures of Sumer and Egypt. He shows a knowledge dependent on physics and astrophysics, which they claimed was imported to them by visitors from Sirius. |
