How Cosmologists Explain the Universe to Friends and Family
Part of the Astronomers' Universe series
This fascinating book provides an accessible and up-to-date overview of modern cosmology. In particular, the book discusses the formation of the Cosmic Microwave Background and the evolution of large-scale structures in the universe, the distribution of galaxies and clusters of galaxies on very large distance scales.
Following a brief introduction, the authors describe the scientific method—how science is done. They then discuss observational cosmology, the instruments and what observations can be done with them, and what is derived from those observations. After discussing the constituents of the universe, including dark matter and dark energy, the authors provide an outline of the forces that shape the universe, with particular emphasis on gravitation. Following this, the reader is taken on a journey in time from the present day back to the very beginning of the universe, a period called inflation, which sets the initial conditions for the subsequent evolution of the universe. The book ends with a brief chapter on what lies beyond.
Written by two experts, the book is aimed at the interested lay-person with little or no physics background, but an interest in modern cosmology.
Terraforming: The Creating of Habitable Worlds
Part of the Astronomers' Universe series
The word “terraforming” conjures up many exotic images and perhaps even wild emotions, but at its core it encapsulates the idea that worlds can be changed by direct human action.
The ultimate aim of terraforming is to alter a hostile planetary environment into one that is Earth-like, and eventually upon the surface of the new and vibrant world that you or I could walk freely about and explore. It is not entirely clear that this high goal of terraforming can ever be achieved, however, and consequently throughout much of this book the terraforming ideas that are discussed will apply to the goal of making just some fraction of a world habitable. In other cases, the terraforming described might be aimed at making a world habitable not for humans but for some potential food source that, of course, could be consumed by humans. The many icy moons that reside within the Solar System, for example, may never be ideal locations for human habitation, but they present the great potential for conversion into enormous hydroponic food-producing centers. The idea of transforming alien worlds has long been a literary backdrop for science fiction writers, and many a make-believe planet has succumbed to the actions of direct manipulation and the indomitable grinding of colossal machines. Indeed, there is something both liberating and humbling about the notion of tra-forming another world; it is the quintessential eucatastrophy espoused by J. R. R. Tolkien, the catastrophe that ultimately brings about a better world. When oxygen was first copiously produced by cyanobacterial activity on the Earth some three billion years ago, it was an act of extreme chemical pollution and a eucatastrophy. The original life-nurturing atmosphere was (eventually) changed f-ever, but an atmosphere that could support advanced life forms came about.
E.T. Talk
How Will We Communicate with Intelligent Life on Other Worlds?
by Fernando J. Ballesteros
Part of the Astronomers' Universe series
For a long time I have been giving scientific lectures in different countries and on diverse topics, generally related to astronomy and to my work at the Arecibo Observatory. No matter which parti- lar topic I am talking about, the same question always comes up: Have we had any contact at Arecibo with "them"? My negative answer does not satisfy anyone. In fact, the answer either confirms their suspicions that there is a conspiracy afoot by higher autho- ties not to release information or their intentions to deceive the general public. The reasons for the deception have to do with the idea that, as in the movie Contact, the received messages contain important and useful information that will bring great advantage to whoever gets it. Many of us want to believe that extraterrestrial creatures can talk to us, that perhaps they are even living among us, as UFO fans believe. It would be fascinating if it were true, a more than extra- dinary discovery, the answer to an eternal question. There is p- sibly a deep psychological motive in this desire to know if we are alone in this huge universe, and the need to believe in something beyond our limited world, in space and time. There is no doubt, then, that this topic brings with it many scientific and philosophical discussions, as well as speculations that, on many occasions, fall into pure pseudoscience because of the lack of a reference framework.
The Alien Communication Handbook
So We Received a Signal-Now What?
Part of the Astronomers' Universe series
Scientists have been searching for signals from extraterrestrial civilizations since Frank Drake's first radio survey in 1960. But what would actually happen if SETI's search succeeds? Is there any way we could even make sense of the signal we receive?
Written by an expert in communication systems and translation technology, this book explores the science of interstellar communication. It explains how this process may unfold, how an ET communication link would work, the types of information it could convey and how professionals, amateurs and ordinary people like you would participate in the effort to understand what another civilization has to say.
Along the way, the book introduces readers to many aspects of modern-day communication systems and computing. Featured as well are dozens of illustrations, photos and real-world examples, rounding out this compelling foray into the mechanics of interstellar communication.
The Mystery of Dark Matter
In Search of the Invisible
Part of the Astronomers' Universe series
Get ready to embark on the exciting search for dark matter-the invisible mass that dominates our universe. This popular science book explains why this mysterious dark matter has been incorporated into the standard model of the universe and how scientists are able to "observe" the invisible.
The book starts with the early indications of the existence of dark matter, including the strange cohesion of galaxy clusters, before moving on to modern observations like cosmic background radiation. Along the way, you will learn about the direct and indirect methods being used by researchers to track down dark matter and whatever is behind this strange phenomenon.
“The Mystery of Dark Matter” will appeal to general readers who wish to understand what scientists actually know about dark matter, along with the methods they use to help crack the mystery.
Weird Worlds
Bizarre Bodies of the Solar System and Beyond
Part of the Astronomers' Universe series
Weird Worlds is the third book in David Seargent's "Weird" series. This book assumes a basic level of astronomical understanding and concentrates on the "odd and interesting" aspects of planetary bodies, including asteroids and moons. From our viewpoint here on Earth, this work features the most unusual features of these worlds and the ways in which they appear "weird" to us. Within our own Solar System, odd facts such as the apparent reversal of the Sun in the skies of Mercury, CO2-driven fountains of dust on Mars, possible liquid water (and perhaps primitive life!) deep within the dwarf planet Ceres, and a variety of odd facts about the planetary moons are all discussed. A special chapter is devoted to Saturn's giant moon Titan, and its methane-based weather system and "hydrological" cycle. This chapter also includes recent speculation on the possibility of methane-based organisms and the form that these might take, if they really do exist. Beyond our Solar System, the book looks at the range of worlds discovered and hypothesized.
In "Weird Worlds," the author discusses planets where temperatures are so high that it rains molten iron, and others so cold that liquid methane floods across plains of ice! Worlds are described where the lightest element acts like a metal and where winds blow at thousands of miles per hour—as well as possible planets whose orbits are essentially parabolic.
In keeping with previous titles in David Seargent's "Weird" series, "Weird Worlds" contains several projects that astronomers of all levels can undertake.
Incoming Asteroid!
What Could We Do About It?
Part of the Astronomers' Universe series
'Incoming Asteroid!' is based on a project within ASTRA (the Association in Scotland to Research into Astronautics) to provide scientific answers to the question – what would we do if we knew there was going to be an asteroid impact in ten years' time or less?
Clearly there are many things humanity can do nothing about, for example an unseen object traveling towards us so fast that we have no time to prepare, or an object so large it may be unstoppable. A realistic hazard model was decided upon, and the scenario developed from that: an incoming object about 1 kilometer in diameter, in an orbit ranging from the outer rim of the Asteroid Belt to within that of Earth's.
Three basic possibilities are considered in this book. The first is the deflection of the asteroid, using remote probes along with a number of possible technologies to change the asteroid's course. Second is the attempt of a manned mission, in order to plant a propulsion system on the asteroid to push it into a different orbit. Third is the nuclear option, a last-ditch attempt to break up and then disperse the asteroid using nuclear weapons. (A rather impractical combination of these second and third options were used as the plot of the popular 1998 Bruce Willis feature film, Armageddon.)
Although the cost of developing the technology needed to protect the Earth would be substantial, there would certainly be spin-off benefits. These could eventually result in practical small-scale atomic energy sources, new propulsion systems that could make extraterrestrial mining within the solar system a possibility, and other as-yet unforeseen benefits.
And finally, Incoming Asteroid! considers the political implications - how governments across the world should best react to the threat with a view to minimizing loss of life, and in the weeks running up to the possible impact, preventing panic in the population.
Unlocking the Secrets of White Dwarf Stars
Part of the Astronomers' Universe series
White dwarfs, each containing about as much mass as our Sun but packed into a volume about the size of Earth, are the endpoints of evolution for most stars. Thousands of these faint objects have now been discovered, though only a century ago only three were known. They are among the most common stars in the Milky Way Galaxy, and they have become important tools in understanding the universe. Yet a century ago only three white dwarfs were known.
The existence of these stars completely baffled the scientists of the day and solving the mysteries of these strange objects required revolutionary advances in science and technology, including the development of quantum physics, the construction and utilization of large telescopes, the invention of the digital computer, and the ability to make astronomical observations from space.
This book tells the story of the growth in our understanding of white dwarf stars, set within the context of the relevant scientific and technological advances. Part popular science, part historical narrative, this book is authored by one of the astrophysicists who participated directly in uncovering some of the secrets of white dwarf stars.
Astronomy's Quest for Sharp Images
From Blurred Pictures to the Very Large Telescope
Part of the Astronomers' Universe series
Since the 1960s, astrophysical discoveries have blossomed, due to the emergence of powerful and new observational tools. Among them, a fantastic improvement of the sharpness of astronomical images, obtained with ground based optical telescopes, has been the result of two revolutions: adaptive optics and optical interferometry.
Written for a general audience, interwoven with fascinating details about the evolution of vision and optics, this book tells a personal story of these revolutions in observational astronomy, born two centuries ago and blossoming in the past fifty years. With the construction of the Very Large Telescope in Chile, Europe played a leading role where young scientists, joining creative astronomers and engineers, have developed a superb creativity. Today, incredibly sharp images of exoplanetary systems and black hole environments are obtained and reveal new questions about Earth-like objects or fundamental physics.
The author has been one of the actors of this adventure. His first-hand testimony is opening the future to new horizons.
Multimessenger Astronomy
Part of the Astronomers' Universe series
Written by a professional astronomer who has worked on a wide spectrum of topics throughout his career, this book gives a popular science level description of what has become known as multimessenger astronomy. It links the new with the traditional, showing how astronomy has advanced at increasing pace in the modern era.
In the second decade of the twenty-first century astronomy has seen the beginnings of a revolution. After centuries when all our information about the Universe has come via electromagnetic waves, now several entirely new ways of exploring it have emerged. The most spectacular has been the detection of gravitational waves in 2015, but astronomy also uses neutrinos and cosmic ray particles to probe processes in the centres of stars and galaxies.
The book is strongly oriented towards measurement and technique. Widely illustrated with colourful pictures of instruments, their creators and astronomical objects, it is backed with descriptions of the underlying theories and concepts, linking predictions, observations and experiments. The thread is largely historical, although obviously it cannot be encyclopaedic. Its point of departure is the beginning of the twentieth century, and it aims at being as complete as possible for the date of completion at the end of 2020.
The book addresses a wide public whose interest in science is served by magazines like Scientific American: lively, intelligent readers but without university studies in physics.
Mystery of the Ashen Light of Venus
Investigating a 400-Year-Old Phenomenon
Part of the Astronomers' Universe series
The "Ashen Light" of Venus-a ghostly emission of light from the night side of our nearest planetary neighbor-is among the last unsolved mysteries of astronomical history. In the four centuries since the phenomenon was first reported, highly reputable visual observers of Venus have recorded seeing the Ashen Light, while others have spent a lifetime searching for it without once being convinced that they ever saw it.
Is the Ashen Light a trick of the eye? The result of a defective lens? A real scientific event?
Occasional references to the Ashen Light are scattered across the literature, yet no work to date has synthesized these records. This book therefore digs deep into the history of the mystery and our latest attempts to understand it, sifting through the clues that might explain whether it is caused by physics, is conjured up by the eye or brain, or a combination of both.
This baffling story will appeal to amateur astronomers, hobbyists, and lay readers interested in joining the debate about one of the most elusive observable phenomena ever recorded in the night sky.
The Universe Today
Our Current Understanding and How It Was Achieved
Part of the Astronomers' Universe series
Starting out from humankind's earliest ideas about the cosmos, this book gives the reader a clear overview of our current understanding of the universe, including big bang theories and the formation of stars and galaxies, as well as addressing open questions. The author shows how our present view gradually developed from observations, and also how the outcome of ongoing research may still change this view. The book brings together concepts in physics and astronomy, including some history in both cases. The text is descriptive rather than technical: the goal is to present things rigorously and without oversimplification, by highlighting the crucial physical concepts. The only prerequisite is a qualitative knowledge of basic physics concepts at high-school level.
Alpha Centauri
Unveiling the Secrets of Our Nearest Stellar Neighbor
Part of the Astronomers' Universe series
As our closest stellar companion and composed of two Sun-like stars and a third small dwarf star, Alpha Centauri is an ideal testing ground of astrophysical models and has played a central role in the history and development of modern astronomy-from the first guesses at stellar distances to understanding how our own star, the Sun, might have evolved. It is also the host of the nearest known exoplanet, an ultra-hot, Earth-like planet recently discovered.
Just 4.4 light years away Alpha Centauri is also the most obvious target for humanity's first directed interstellar space probe. Such a mission could reveal the small-scale structure of a new planetary system and also represent the first step in what must surely be humanity's greatest future adventure-exploration of the Milky Way Galaxy itself.
For all of its closeness, α Centauri continues to tantalize astronomers with many unresolved mysteries, such as how did it form, how many planets does it contain and where are they, and how might we view its extensive panorama directly?
In this book we move from the study of individual stars to the study of our Solar System and our nearby galactic neighborhood. On the way we will review the rapidly developing fields of exoplanet formation and detection.
Visible and Invisible
The Wonders of Light Phenomena
Part of the Astronomers' Universe series
Light phenomena have intrigued humankind since prehistory. Think of the rainbow, a sunset on the sea, a game of shadows. Humans have always used light for their own needs, from cooking food to illuminating a room.
However, light is not only limited to what we can see with our eyes. The invisible part of the electromagnetic spectrum is broad and dynamic. This book outlines the mysteries and wonders of electromagnetism, heat, and light. It also covers the history of our scientific understanding of light.
The dark as well as the bright sides of light are fully explored in these pages, from their impact on our world to their use in cutting-edge technologies in a variety of fields. Numerous full-color images and drawings complement the text, and light phenomena are explained in a simple and engaging way.
Making Waves
The Story Of Ruby Payne-scott: Australian Pioneer Radio Astronomer
Part of the Astronomers' Universe series
This book is an abbreviated, partly re-written version of "Under the Radar - The First Woman in Radio Astronomy: Ruby Payne-Scott." It addresses a general readership interested in historical and sociological aspects of astronomy and presents the biography of Ruby Payne-Scott (1912 – 1981). As the first female radio astronomer (and one of the first people in the world to consider radio astronomy), she made classic contributions to solar radio physics.
She also played a major role in the design of the Australian government's Council for Scientific and Industrial Research radars, which were in turn of vital importance in the Southwest Pacific Theatre in World War II. These radars were used by military personnel from Australia, the United States and New Zealand. From a sociological perspective, her career offers many examples of the perils of being a female academic in the first half of the 20th century.
Written in an engaging style and complemented by many historical photographs, this book offers fascinating insights into the beginnings of radio astronomy and the role of a pioneering woman in astronomy. To set the scene, the first colourfully illustrated chapter presents an overview of solar astrophysics and the tools of the radio astronomer.
From the reviews of "Under the Radar":
"This is a beautifully-researched, copiously-illustrated and well-written book that tells us much more than the life of one amazing female radio astronomer. It also provides a profile on radar developments during WWII and on Australia's pre-eminent place in solar radio astronomy in the years following WWII. Under the Radar is compelling reading, and if you have taken the time to read right through this review then it certainly belongs on your bookshelf!" (Wayne Orchiston, Journal of Astronomical History and Heritage, March, 2010)
Classifying the Cosmos
How We Can Make Sense of the Celestial Landscape
Part of the Astronomers' Universe series
Since the invention of the telescope 400 years ago, astronomers have rapidly discovered countless celestial objects. But how does one make sense of it all?
Astronomer and former NASA Chief Historian Steven J. Dick brings order to this menagerie by defining 82 classes of astronomical objects, which he places in a beginner-friendly system known as "Astronomy's Three Kingdoms." Rather than concentrating on technicalities, this system focuses on the history of each object, the nature of its discovery, and our current knowledge about it.
The ensuing book can therefore be read on at least two levels. On one level, it is an illustrated guide to various types of astronomical wonders. On another level, it is considerably more: the first comprehensive classification system to cover all celestial objects in a consistent manner.
Accompanying each spread are spectacular historical and modern images. The result is a pedagogical tour-de-force, whereby readers can easily master astronomy's three realms of planets, stars, and galaxies.
Orreries, Clocks, and London Society
The Evolution of Astronomical Instruments and Their Makers
Part of the Astronomers' Universe series
Orreries-mechanical models of the Solar System and its motions-are found everywhere. They appear in paintings, on computers, across natural landscapes, and in museums all over the world. The more you look, the more you find, yet their significance is often overlooked aside other great astronomical inventions.
This book reclaims the history of the orrery, offering a fascinating look into its evolution over the centuries. With a particular focus on London society and clockmakers, it weaves together historical narrative with practical know-hows and scientific fact, showing how the orrery changed from a fanciful toy to a high-tech instrument to a vessel for art and education.
The first edition, Orrery, explained what an orrery is and how it got its name. This revised edition goes several steps further, tracing the instrument back to the time of Ptolemy and forward to planetariums and star projectors. In addition, it features new sections on how to construct your own orrery at home.
This book will appeal to anybody interested in astronomical mechanical devices, scientific instruments, horology, or the history of clocks.
Worlds Beyond Our Own
The Search for Habitable Planets
Part of the Astronomers' Universe series
This is a book on planets: Solar system planets and dwarf planets. And planets outside our solar system—exoplanets. How did they form? What types of planets are there and what do they have in common? How do they differ? What do we know about their atmospheres—if they have one? What are the conditions for life and on which planets may they be met? And what's the origin of life on Earth and how did it form? You will understand how rare the solar system, the Earth and hence life is.
This is also a book on stars. The first and second generation of stars in the Universe. But in particular also on the link between planets and stars—brown dwarfs. Their atmospheric properties and similarities with giant exoplanets.
All these fascinating questions will be answered in a non-technical manner. But those of you who want to know a bit more may look up the relevant mathematical relationships in appendices.
Understanding Gravitational Waves
Part of the Astronomers' Universe series
The birth of a completely new branch of observational astronomy is a rare and exciting occurrence. For a long time, our theories about gravitational waves-proposed by Albert Einstein and others more than a hundred years ago-could never be fully proven, since we lacked the proper technology to do it.
That all changed when, on September 14, 2015, instruments at the LIGO Observatory detected gravitational waves for the first time.
This book explores the nature of gravitational waves-what they are, where they come from, why they are so significant and why nobody could prove they existed before now. Written in plain language and interspersed with additional explanatory tutorials, it will appeal to lay readers, science enthusiasts, physical science students, amateur astronomers and to professional scientists and astronomers.
Exploring the Ocean Worlds of Our Solar System
Part of the Astronomers' Universe series
In the last 25 years, planetary science experienced a revolution, as vast oceans of liquid water have been discovered within the heart of the icy moons of our Solar System. These subsurface oceans lie hidden under thick layers of ice. We call them ocean worlds.
Some of these icy moons, such as Ganymede, may hold two to three times more liquid water than all the water present on Earth, while others, such as Enceladus and Europa, are thought by astrobiologists to be our best hope of finding extraterrestrial life.
In this book, we will explore and compare a variety of Solar System ocean worlds, meeting in the process 22 of the most intriguing objects, from the giant asteroid Ceres to the enigmatic, distant Sedna. In doing so, we will also encounter the multiple spacecraft that brought back most of what we know of these worlds (Pioneers, Voyagers, Cassini-Huygens, etc.), as well as the latest scientific research on this new topic.
We will also entertain the possibility of life on each of these ocean worlds by assessing their habitability, as ultimately, these ocean worlds might hold the key to answering the fundamental questions in life: How did life appear? Where do we come from? Is there life out there?
With the contributions of leading planetary scientists from NASA, ESA, and other institutions, this book aims to be the go-to reference for anyone wanting to know more about this fascinating topic.
Astrobiological Neurosystems
Rise and Fall of Intelligent Life Forms in the Universe
Part of the Astronomers' Universe series
This book explains why scientists believe that life may be more common in the Universe than previously considered possible. It presents the tools and strategies astronomers and astrobiologists are using in their formal search for habitable exoplanets as well as more advanced forms of life in other parts of our galaxy. The author then summarizes what is currently known about how and where organic molecules critical to our form of carbon-based life are manufactured.
The core of the book explains (and presents educated guesses) how nervous systems evolved on Earth, how they work, and how they might work on other worlds. Combining his knowledge of neuroscience, computers, and astrobiology the author jumps into the discussion whether biological nervous systems are just the first step in the rise of intelligence in the Universe.
The book ends with a description from both the psychologist's and the neuroscientist's viewpoints, exactly what it is about the fields of astrobiology and astronomy that "boggles the minds" of many amateur astronomers and interested non-scientists.
This book stands out from other popular science books on astrobiology by making the point that "astro-neurobiologists" need to begin thinking about how alien nervous systems might work.
The Chemical Cosmos
A Guided Tour
Part of the Astronomers' Universe series
If you have ever wondered how we get from the awesome impersonality of the Big Bang universe to the point where living creatures can start to form, and evolve into beings like you, your friends and your family, wonder no more. Steve Miller provides us with a tour through the chemical evolution of the universe, from the formation of the first molecules all the way to the chemicals required for life to evolve. Using a simple Hydrogen molecule — known as H-three-plus - as a guide, he takes us on a journey that starts with the birth of the first stars, and how, in dying, they pour their hearts out into enriching the universe in which we live.
Our molecular guide makes its first appearance at the source of the Chemical Cosmos, at a time when only three elements and a total of 11 molecules existed. From those simple beginnings, H-three-plus guides us down river on the violent currents of exploding stars, through the streams of the Interstellar Medium, and into the delta where new stars and planets form. We are finally left on the shores of the sea of life. Along the way, we meet the key characters who have shaped our understanding of the chemistry of the universe, such as Cambridge physicist J.J. Thomson and the Chicago chemist Takeshi Oka. And we are given an insider's view of just how astronomers, making use of telescopes and Earth-orbiting satellites, have put together our modern view of the Chemical Cosmos.
Universe Unveiled
The Cosmos in My Bubble Bath
Part of the Astronomers' Universe series
The bubbles were swirling all around me, massaging my body. As I luxuriated in this fantastic bath, I gasped realizing that those bubbles carried with them miniature galaxies bringing the entire Cosmos into my bathtub...
Alfie is back. And so are George and other characters from the author's previous book Einstein's Enigma or Black Holes in My Bubble Bath. While the present book, Universe Unveiled - The Cosmos in My Bubble Bath, is completely independent, its storyline can be considered a sequel to the previous one. The scientific content spanning ancient world models to the most recent mysteries of cosmology is presented in an entirely nontechnical and descriptive style through the discussions between Alfie, the enlightened learner, and George, professor of astrophysics. Fantasies, based on these discussions that cover the scientific facts, are created by the magical bubble baths taken by Alfie.
Universe Unveiled blends accurate science with philosophy, drama, humour, and fantasy to create an exciting cosmic journey that reads like a novel and educates as it entertains.
Under a Crimson Sun
Prospects for Life in a Red Dwarf System
Part of the Astronomers' Universe series
Gliese 581 is a red dwarf star some 20.3 light years from Earth. Red dwarfs are among the most numerous stars in the galaxy, and they sport diverse planetary systems. At magnitude 10, Gliese 581 is visible to amateur observers but does not stand out. So, what makes this star so important? It is that professional observers have confirmed that it has at least four planets orbiting it, and in 2009, Planet d was described in the letters of The Astrophysical Journal as "the first confirmed exoplanet that could support Earth-like life."
“Under a Crimson” Sun looks at the nature of red dwarf systems such as Gliese as potential homes for life.
Realistically, what are prospects for life on these distant worlds? Could life evolve and survive there? How do these planetary surfaces and geology evolve? How would life on a red dwarf planet differ from life on Earth? And what are the implications for finding further habitable worlds in our galaxy?
Stevenson provides readers with insight into the habitability of planets and how this changes as time progresses and the central star evolves. Explore with him in this engaging, fascinating book the possibilities for finding life, from bacteria to more complex and even intelligent organisms, on red dwarf system planets.
Orrery
A Story Of Mechanical Solar Systems, Clocks, And English Nobility
Part of the Astronomers' Universe series
"Orrery" appeals to almost anyone interested in popular astronomy, astronomical mechanical devices, scientific instruments, the history of clocks - and even the history of aristocratic and prestigious families! Many people these days – not only astronomers – have a good idea of the main components of the Solar System. They might also know about the orrery, a mechanical model that shows the movements of the Moon and planets. But not too many know why it was so named and who it was named after. The Boyle family – the Earls of Orrery –include the famous Boyle of Boyle's Law. But others were key in the history of the orrery, not the least being clockmakers. Aware of the lunar and planetary content of the sky, they strove to make scientific instruments to demonstrate their movements and introduced measuring devices to predict their positions. In antiquity, their lives on occasion depended on the accuracy; upsetting kings and lords was dangerous business!
Orreries are found everywhere. They can be made of wood or metal, and are even available today as home-assembly kits and children's toys. They appear in paintings, on computers, on the side of royal clocks, in stately home hallways, and of course, in museums all over the world. This book contains illustrations of orreries to give a guide as to what is and was available and where to see the best examples. It also contains information and references to help readers who want to make (or buy) their own orrery.
The story of the Boyles is not just relevant to a tiny corner of Ireland, but spans the world. "Orrery" highlights the process of discovery and humankind's universal fascination with the heavens. Provides a fascinating example of the relationship between innovative thinking (invention) and precision engineering (execution).
Cosmic Dawn
The Search For The First Stars And Galaxies
Part of the Astronomers' Universe series
This book takes the reader on an exploration of the structure and evolution of our universe. The basis for our knowledge is the Big Bang theory of the expanding universe. This book then tells the story of our search for the first stars and galaxies using current and planned telescopes. These telescopes are marvels of technology far removed from Galileo's first telescope but continuing astronomy in his ground breaking spirit. We show the reader how these first stars and galaxies shaped the universe we see today. This story is one of the great scientific adventures of all time.
