Giordano Bruno's The Ash Wednesday Supper is the first of six philosophical dialogues in Italian that he wrote and published in London between 1584 and 1585. It presents a revolutionary cosmology founded on the new Copernican astronomy that Bruno extends to infinite dimensions, filling it with an endless number of planetary systems. As well as opening up the traditional closed universe and reducing earth to a tiny speck in an overwhelmingly immense cosmos, Bruno offers a lively description of his clash of opinions with the conservative academics and theologians he argued with in Oxford and London. This volume, containing what has recently been claimed as the final version of Bruno's Ash Wednesday Supper, presents a new translation based on a newly edited text, with critical comment that takes account of the most current discussion of the textual, historical, cosmological and philosophical issues raised in this dialogue. It considers Bruno's work as a seminal text of the late European renaissance.

Magnetic fields pervade the universe and play an important role in many astrophysical processes. However, they require specialised observational tools, and are challenging to model and understand. This volume provides a unified view of magnetic fields across astrophysical and cosmological contexts, drawing together disparate topics that are rarely covered together. Written by the lecturers of the XXV Canary Islands Winter School, it offers a self-contained introduction to cosmic magnetic fields on a range of scales. The connections between the behaviours of magnetic fields in these varying contexts are particularly emphasised, from the relatively small and close ranges of the Sun, planets and stars, to galaxies and clusters of galaxies, as well as on cosmological scales. Aimed at young researchers and graduate students, this up-to-date review uniquely brings together a subject often tackled by disconnected communities, conveying the latest advances as well as highlighting the limits of our current understanding.

"This book is an attempt to demystify the activities of a celestial object such as the Sun appealing to basic physics already available to high school students. Building on simple logic, the contents begin with measurements of the gross properties of the Sun like size (volume) and mass from which the average density of solar material is shown to be almost equal to water's density. Then the temperature is obtained using the colour of sunlight, and the gravitational force is discussed to indicate how the solar material is compressed at the centre of the Sun leading to heating which further causes nuclear reactions. The roles of all the forces of nature, viz. strong, weak, electromagnetic and gravitation are shown in the construction of the Sun. The generation of magnetic fields by solar rotation and the eruptions of solar atmospheric material are also included. To further demystify the methods of obtaining all such facts about the Sun, a chapter is solely devoted to the different kinds of solar telescopes operating at different wavelengths and also at different locations ranging from outer space to deep underground, where solar neutrino flux is measured. The entire discussion is interspersed with historical encounters between giants of science to show the human face of scientific research."--Publisher's website.

This research monograph presents a new dynamical framework for the study of secular morphological evolution of galaxies along the Hubble sequence. Classical approaches based on Boltzmann's kinetic equation, as well as on its moment-equation descendants the Euler and Navier-Stokes fluid equations, are inadequate for treating the maintenance and long-term evolution of systems containing self-organized structures such as galactic density-wave modes. A global and synthetic approach, incorporating correlated fluctuations of the constituent particles during a nonequilibrium phase transition, is adopted to supplement the continuum treatment. The cutting-edge research combining analytical, N-body simulational, and observational aspects, as well as the fundamental-physics connections it provides, make this work a valuable reference for researchers and graduate students in astronomy, astrophysics, cosmology, many-body physics, complexity theory, and other related fields. Contents Dynamical Drivers of Galaxy Evolution N-Body Simulations of Galaxy Evolution Astrophysical Implications of the Dynamical Theory Putting It All Together Concluding Remarks Appendix: Relation to Kinetics and Fluid Mechanics.

"Formerly the domain of fiction, moving human civilization to the stars is increasingly becoming a scientific possibility--and a necessity. Whether in the near future due to climate change and the depletion of finite resources, or in the distant future due to catastrophic cosmological events, we must face the reality that humans will one day need to leave planet Earth to survive as a species. World-renowned physicist and futurist Michio Kaku explores in rich, intimate detail the process by which humanity may gradually move away from the planet and develop a sustainable civilization in outer space. He reveals how cutting-edge developments in robotics, nanotechnology, and biotechnology may allow us to terraform and build habitable cities on Mars. He then takes us beyond the solar system to nearby stars, which may soon be reached by nanoships traveling on laser beams at near the speed of light. Finally, he brings us beyond our galaxy, and even beyond our universe, to the possibility of immortality, showing us how humans may someday be able to leave our bodies entirely and laser port to new havens in space. With irrepressible enthusiasm and wonder, Dr. Kaku takes readers on a fascinating journey to a future in which humanity may finally fulfill its long-awaited destiny among the stars"-- Provided by publisher.

"This book is about the history and the current state of the art in the exciting field of cosmology — the science about the Universe as a whole, which is guaranteed to attract the attention of a wide range of readers. It mostly aims to explain the main ideas of modern cosmology: the expanding Universe, its creation in a Big Bang, its evolution, characteristics, and structure, as well as issues — dark matter and dark energy, black holes and other exotic objects etc. It also answers most frequently asked questions about cosmology. How the Universe Works stands between a popular science book and a textbook, acting as a sort of a bridge across the great chasm separating popular science from true science. It can be also used as an introductory textbook for undergraduate students. It is also suitable for the non-experts in cosmology who wish to have an overview of the current state of the field. It is different from most popular science books because it avoids cutting corners in explanations and contains justification for various assumptions or estimations made in cosmology. It does not hide problems faced by modern cosmology as well as issues the community has no consensus about. It also does not try to pass hypotheses for established theories, which is not uncommon in scholarly articles."-- Provided by publisher.

This book is an important text of the Kerala school of astronomy and mathematics, probably composed in the 16th century. In the Indian astronomical tradition, the karana texts are essentially computational manuals, and they often display a high level of ingenuity in coming up with simplified algorithms for computing planetary longitudes and other related quantities. Karanapaddhati, however, is not a karana text. Rather, it discusses the paddhati or the rationale for arriving at suitable algorithms that are needed while preparing a karana text for a given epoch. Thus the work is addressed not to the almanac maker but to the manual maker. Karanapaddhati presents the theoretical basis for the vakya system, where the true longitudes of the planet are calculated directly by making use of certain auxiliary notions such as the khanda, mandala and dhruva along with tabulated values of changes in the true longitude over certain regular intervals which are expressed in the form of vakyas or mnemonic phrases. The text also discusses the method of vallyupasamhara, which is essentially a technique of continued fraction expansion for obtaining optimal approximations to the rates of motion of planets and their anomalies, involving ratios of smaller numbers. It also presents a new fast convergent series for Ï which is not mentioned in the earlier works of the Kerala school. As this is a unique text presenting the rationale behind the vakya system and the computational procedures used in the karana texts, it would serve as a useful companion for all those interested in the history of astronomy. The authors have provided a translation of the text followed by detailed notes which explain all the computational procedures, along with their rationale, by means of diagrams and equations.

An observatory and a lighthouse form the nexus of this major new investigation of science, religion, and the state in late Ottoman Egypt. Astronomy, imperial bureaucrats, traditionally educated Muslim scholars, and reformist Islamic publications, such as The Lighthouse, are linked to examine the making of knowledge, the performance of piety, and the operation of political power through scientific practice. Contrary to ideas of Islamic scientific decline, Muslim scholars in the nineteenth century used a dynamic tradition of knowledge to measure time, compute calendars, and predict planetary positions. The rise of a 'new astronomy' is revealed to owe much to projects of political and religious reform: from the strengthening of the multiple empires that exercised power over the Nile Valley; to the 'modernization' of Islamic centers of learning; to the dream of a global Islamic community that would rely on scientific institutions to coordinate the timing of major religious duties.

What is time made of? We might balk at such a question, and reply that time is not made of anything--it is an abstract and universal phenomenon. In Making Time, Yulia Frumer upends this assumption, using changes in the conceptualization of time in Japan to show that humans perceive time as constructed and concrete. In the mid-sixteenth century, when the first mechanical clocks arrived in Japan from Europe, the Japanese found them interesting but useless, because they failed to display time in units that changed their length with the seasons, as was customary in Japan at the time. In 1873, however, the Japanese government adopted the Western equal-hour system as well as Western clocks. Given that Japan carried out this reform during a period of rapid industrial development, it would be easy to assume that time consciousness is inherent to the equal-hour system and a modern lifestyle, but Making Time suggests that punctuality and time-consciousness are equally possible in a society regulated by a variable-hour system, arguing that this reform occurred because the equal-hour system better reflected a new conception of time--as abstract and universal--which had been developed in Japan by a narrow circle of astronomers, who began seeing time differently as a result of their measurement and calculation practices. Over the course of a few short decades this new way of conceptualizing time spread, gradually becoming the only recognized way of treating time.

John Stanley Plaskett was Canada's pre-eminent astronomer in the first half of the twentieth century. His legacy lives on in the observatory he founded in Victoria, British Columbia, and the reputation he built for Canada as a nation making vital contributions to basic science. Plaskett's pioneering work with the most massive stars and his definitive determination of the rotation of the Milky Way Galaxy earned him international recognition of the highest order. Northern Star explores Plaskett's unorthodox and fascinating life from his rural roots near Woodstock, Ontario through his days as a technician at the University of Toronto to his initiation in astronomy at the Dominion Observatory in Ottawa. His greatest achievements followed after he persuaded the government of Canada, in spite of the strictures of the First World War, to finance what was then the world's largest operational telescope. Peter Broughton's accessible and engaging prose illuminates Plaskett's numerous achievements and the social, political, economic, and religious milieu surrounding them. This richly illustrated volume invites readers to understand the pull that Plaskett's passions, personality, and motivations exerted on him during his lifetime.

"Nuclear planetary science has come to play an important role in our understanding of the origin and evolution of the planetary bodies in our solar system. A newly established branch of planetary science, its study aids in humankind's exploration of the present states of the structures of various planetary bodies (including the Earth), their atmospheres and their satellites, as well as small celestial bodies (e.g. asteroids), through direct observation. Knowing the elemental composition of the planetary bodies is essential in order to understand the formation and evolution of planetary bodies — just as important as it is to know the mass, radius, density and orbit of the celestial body. Suitable for students and specialists interested in the much wider field of Earth and Planetary Science, topics related to the planets and asteroids in the solar system are dealt with in this book. Techniques related to nuclear planetary science's nuclear cosmochemical and geological methods are also covered in this book."--Publisher's website.

"Since several decades, comets have been considered as key witnesses of solar system formation. Their nature has been explored using the modern arsenal of Earth- and space-based observations, and they hold a central place as dynamical arbiters of the planetary system in the new paradigm of solar system evolution known as the Nice Model. Thus, they have the potential to test the various ideas, using the detailed data recently gathered by the ESA/Rosetta mission. This requires an understanding of their origin and evolution, which form the subject of the present book. All the relevant issues are covered2, describing both the background and the current frontiers of research."--Publisher's website.
