Download or read book The Enigma of Money written by Makoto Nishibe and published by Springer. This book was released on 2016-10-24 with total page 103 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a new way of understanding modern money and markets by stressing their self-fulfilling/self-destructive properties as institutions from evolutionary perspectives. In contrast to an unrealistic view of the neoclassical general equilibrium theory that models the price mechanism of a “concentrated market” without using money, presented here is an alternative theory of markets on how a realistic “dispersive market” using a stock of money and inventory as buffers can work as a multilayered price-quantitative adjustment system. The central features of modern sovereign moneys seen in inconvertible IOUs of central banknotes can be depicted as “The Emperor's New Clothes” that correspond to the U.S. dollar and the Euro void of their own value. The image captures such characteristics of national currencies as “self-fulfilling ideas” by the inertia of conventions in the past and expectations of an uncertain future. Both ideas normally make money more acceptable and circulative so that its value can become more stable unless expectations for the future turn very pessimistic. The same logic also applies to such other currencies as Bitcoin and community currencies. Their recent diffusion has shown that Hayek's idea of denationalization of money and competition between multiple currencies in terms of its qualities, not its quantities sought as in ongoing quantitative easing, become more relevant under current situations. The qualities of money refer not only to stable monetary values and low transaction costs, but also to high ability in creating, sharing, and communicating social and cultural value. The potential of the logic of self-fulfillment of ideas can thus open up a new economic society when we realize that such various non-national currencies all depend on the same logic of money.

Download or read book Chasing the Sun written by Richard Cohen and published by Simon and Schuster. This book was released on 2011-08-04 with total page 659 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Sun is so powerful, so much bigger than us, that it is a terrifying subject. Yet though we depend on it, we take it for granted. Amazingly the first book of its kind, CHASING THE SUNis a cultural and scientific history of our relationship with the star that gives us life. Richard Cohen, applying the same mix of wide-ranging reference and intimate detail that won outstanding reviews for By the Sword, travels from the ancient Greek astronomers to modern-day solar scientists, from Stonehenge to Antarctica (site of the solar eclipse of 2003, when penguins were said to sing), Mexico's Aztecs to the Norwegian city of Tromso, where for two months of the year there is no Sun at all. He introduces us to the crucial 'sunspot cycle' in modern economics, the religious dances of Indian tribesmen, the histories of sundials and calendars, the plight of migrating birds, the latest theories of global warming, and Galileo recording his discoveries in code, for fear of persecution. And throughout, there is the rich Sun literature -- from the writings of Homer through Dante and Nietzsche to Keats, Shelley and beyond. Blindingly impressive and hugely readable, this is a tour de force of narrative non-fiction.
Download or read book The Sun s Heartbeat written by Bob Berman and published by Little, Brown. This book was released on 2011-07-13 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: The beating heart of the sun is the very pulse of life on earth. And from the ancients who plotted its path at Stonehenge to the modern scientists who unraveled the nuclear fusion reaction that turns mass into energy, humankind has sought to solve its mysteries. In this lively biography of the sun, Bob Berman ranges from its stellar birth to its spectacular future death with a focus on the wondrous and enthralling, and on the heartbreaking sacrifice, laughable errors, egotistical battles, and brilliant inspirations of the people who have tried to understand its power. What, exactly, are the ghostly streaks of light astronauts see-but can't photograph-when they're in space? And why is it impossible for two people to see the exact same rainbow? Why are scientists beginning to think that the sun is safer than sunscreen? And how does the fluctuation of sunspots-and its heartbeat-affect everything from satellite communications to wheat production across the globe? Peppered with mind-blowing facts and memorable anecdotes about spectral curiosities-the recently-discovered "second sun" that lurks beneath the solar surface, the eerie majesty of a total solar eclipse-The Sun's Heartbeat offers a robust and entertaining narrative of how the Sun has shaped humanity and our understanding of the universe around us.

Download or read book The Sun Recorded Through History written by J.M. Vaquero and published by Springer Science & Business Media. This book was released on 2009-04-21 with total page 395 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Sun is nowadays observed using di?erent techniques that provide an almost instantaneous 3-D map of its structure. Of particular interest is the studyofthevariabilityinthesolaroutputproducedbythedissipationofm- netic energy on di?erent spatial and temporal scales – the so-called magnetic activity. The 11-year cycle is the main feature describing this phenomenon. Apart from its intrinsic scienti?c interest, this topic is worth studying because of the interaction of such processes with the terrestrial environment. A ?eet of space and ground-based observatories are currently monitoring the behaviour of our star on a daily basis. However, solar activity varies not only on this decadal time-scale, as has been attested mainly through two methods: (a) records of the number of sunspots observed on the solar surface from 1610, and (b) the records of 14 10 cosmogenic isotopes, such as Cand Be, measured in tree-rings and i- cores, respectively. The study of the long-term behaviour of solar activity may be comp- mented by the study of historical accounts describing phenomena directly or indirectly related to solar activity. Numerous scienti?c and non-scienti?c d- uments have reported these events and we can make use of them as a proxy of solar activity in past times.

Download or read book Applied and Computational Historical Astronomy Angewandte und computergest tzte historische Astronomie written by Gudrun Wolfschmidt and published by tredition. This book was released on 2021-08-26 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: 'Computational History' derives history from data and nowadays, therefore, relies on the technologies of the digital humanities. 'Computational History of Science' addresses questions of history by evaluating historical data, e.g. for tracing back copying traditions and conclude on transfer and transformation of data and knowledge. The term 'Applied Historical Astronomy', in contrast, tries to address questions of contemporary science by evaluating historical data in comparison with most recent data. This opens new possibilities, e.g. in the search for stellar transients among historical data. In the contribution by Hoffmann & Vogt we will focus on the stellar transients among all the topics mentioned above. Philipp Protte discusses the accuracy of magnitudes and positions in ancient star catalogues, Andreas Schrimpf & Frank Verbunt present an analysis of an early modern star catalogue. Victor Reijs analyses the visibility of celestial objects for naked-eye observers, and Björn Kunzmann showcases some important variable stars in the history of astronomy. Rene Hudec presents astronomical photographic archives as a valuable data source for modern astrophysics. José M. Vaquero discusses the studies on solar observations made during the last four centuries. More technical are the contributions of Georg Zotti on Stellarium and Karsten Markus-Schnabel on data-mining and data-processing technologies. Ido Yavetz & Luca Beisel are developing a digital tool of computational history of science for the simulation of pre-modern astronomical models. Gerd Graßhoff focuses more on the application of computational history with regard to Kepler's Astronomia Nova while Tim Karberg presents an analysis of the astronomical orientation of buildings in the North Sudan.

Book excerpt: THE FINAL & ULTIMATE DAYS ON EARTH 2020 I have spent the last 32 years of my life as a student of Biblical prophecies and as an end time watchman of the Lords land of America. The time has come for the house of Israel, to depart from the land of Babylon America. The span of 390 years, as laid down by the Lord from 1620 was over (Eze. 4:9). After the Second World War, immigrants came to heal American financial woes, but her financial health has not healed. The prophesied 390 years was over in 2010; the house of Israeli Americans and immigrants must prepare themselves for their Exodus from the land of America (Jer. 51:9), which is leading for desolation on March 14, 2017. This inevitable downfall will be triggered by the Ballistic Nuclear missiles deployed by the whole world falling on the land of America (Jer. 51:49). I dare to attempt to write something of this magnitude and I am supremely confident that what I am writing is what is written as the Lords prophecy. The time line schedule and the Dates concerning the Final and Ultimate days on Earth 2020 are those the Lord revealed to me and as written in the scriptures. I strongly encourage every one of you to read every word of the Lord written in this book and you have nothing to lose but everything to gain. I have never been more confident of anything in my entire life. The evidence presented in the scripture, that mighty nation America would be born in the second wilderness 392 years ago (Jer. 5:15; Hos. 2:14), and the sudden 9/11 jet engines of war by the terrorists against the World Trade center and the Pentagon (Ez. 26:9/11), and the sudden destruction are extremely compelling on America!!! You must read His every word and rescue as many American citizens and immigrants as possible from the Lords land of America (Hos. 9:3; Deut. 26:68). According to the written words of the LORD Almighty in the Bible, The TRUMP from TYRUS will easily win the 2012 American Presidential election. There will be no election in 2016. Why? Both the Trump and the Trumpet will play significant roles in the incursion of THE WRATH. Please read all about these and more in this book.
Download or read book Nature s Third Cycle written by Arnab Rai Choudhuri and published by OUP Oxford. This book was released on 2015-01-29 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: The cycle of day and night and the cycle of seasons are two familiar natural cycles around which many human activities are organized. But is there a third natural cycle of importance for us humans? On 13 March 1989, six million people in Canada went without electricity for many hours: a large explosion on the sun was discovered as the cause of this blackout. Such explosions occur above sunspots, dark features on the surface of the Sun that have been observed through telescopes since the time of Galileo. The number of sunspots has been found to wax and wane over a period of 11 years. Although this cycle was discovered less than two centuries ago, it is becoming increasingly important for us as human society becomes more dependent on technology. For nearly a century after its discovery, the cause of the sunspot cycle remained completely shrouded in mystery. The 1908 discovery of strong magnetic fields in sunspots made it clear that the 11-year cycle is the magnetic cycle of the sun. It is only during the last few decades that major developments in plasma physics have at last given us the clue to the origins of the cycle and how the large explosions affecting the earth arise. Nature's Third Cycle discusses the fascinating science behind the sunspot cycle, and gives an insider's perspective of this cutting-edge scientific research from one of the leaders of the field.
Download or read book How We See the Sky written by Thomas Hockey and published by University of Chicago Press. This book was released on 2011-09-12 with total page 251 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gazing up at the heavens from our backyards or a nearby field, most of us see an undifferentiated mess of stars—if, that is, we can see anything at all through the glow of light pollution. Today’s casual observer knows far less about the sky than did our ancestors, who depended on the sun and the moon to tell them the time and on the stars to guide them through the seas. Nowadays, we don’t need the sky, which is good, because we’ve made it far less accessible, hiding it behind the skyscrapers and the excessive artificial light of our cities. How We See the Sky gives us back our knowledge of the sky, offering a fascinating overview of what can be seen there without the aid of a telescope. Thomas Hockey begins by scanning the horizon, explaining how the visible universe rotates through this horizon as night turns to day and season to season. Subsequent chapters explore the sun’s and moon’s respective motions through the celestial globe, as well as the appearance of solstices, eclipses, and planets, and how these are accounted for in different kinds of calendars. In every chapter, Hockey introduces the common vocabulary of today’s astronomers, uses examples past and present to explain them, and provides conceptual tools to help newcomers understand the topics he discusses. Packed with illustrations and enlivened by historical anecdotes and literary references, How We See the Sky reacquaints us with the wonders to be found in our own backyards.

Available in PDF, EPUB and Kindle. Book excerpt: This book contains some questions that arise in our mind quite frequently. The questions are as follows: 1. Why is everything in this universe changing? 2. What is the reason behind creation and destruction? 3. What is the reason behind birth and death? 4. Where have we come from? 5. What is our destination? 6. Is there any God? If so, where is He and what does He look like? 7. Can God do everything that He wants to? Can He make so big a stone that He cannot lift? 8. Is creation and destruction a resultant of time or nature? An attempt has been made to answer these questions in this book. Since people are interested in the scientific view for answer to any type of question, an effort has been made to answer these questions from a scientific angle.
Download or read book Confronting The Enigma Of Time written by John R Fanchi and published by World Scientific. This book was released on 2023-03-14 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Newton's classical mechanics, time played the role of a monotonically increasing evolution parameter. Einstein rejected the Newtonian concept and instead identified time as the fourth coordinate of a space-time four-vector. Today, scientists are considering different concepts of time as a means of resolving incompatibilities between relativity and quantum mechanics. Some view time as an emergent property of a system rather than a fundamental property, while others consider two temporal variables. The purpose of this book is to examine the role of time in modern physics so that the reader gains an increased awareness of time and its place in our understanding of nature.

Download or read book Descartes Agonistes written by John Schuster and published by Springer Science & Business Media. This book was released on 2012-10-23 with total page 643 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reconstructs key aspects of the early career of Descartes from 1618 to 1633; that is, up through the point of his composing his first system of natural philosophy, Le Monde, in 1629-33. It focuses upon the overlapping and intertwined development of Descartes’ projects in physico-mathematics, analytical mathematics, universal method, and, finally, systematic corpuscular-mechanical natural philosophy. The concern is not simply with the conceptual and technical aspects of these projects; but, with Descartes’ agendas within them and his construction and presentation of his intellectual identity in relation to them. Descartes’ technical projects, agendas and senses of identity shifted over time, entangled and displayed great successes and deep failures, as he morphed from a mathematically competent, Jesuit trained graduate in neo-Scholastic Aristotelianism to aspiring prophet of a systematised corpuscular-mechanism, passing through stages of being a committed physico-mathematicus, advocate of a putative ‘universal mathematics’, and projector of a grand methodological dream. In all three dimensions—projects, agendas and identity concerns—the young Descartes struggled and contended, with himself and with real or virtual peers and competitors, hence the title ‘Descartes-Agonistes’.
Download or read book The Cambridge World History Volume 1 Introducing World History to 10 000 BCE written by David Christian and published by Cambridge University Press. This book was released on 2015-04-09 with total page 907 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volume 1 of the Cambridge World History is an introduction to both the discipline of world history and the earliest phases of world history up to 10,000 BCE. In Part I leading scholars outline the approaches, methods, and themes that have shaped and defined world history scholarship across the world and right up to the present day. Chapters examine the historiographical development of the field globally, periodisation, divergence and convergence, belief and knowledge, technology and innovation, family, gender, anthropology, migration, and fire. Part II surveys the vast Palaeolithic era, which laid the foundations for human history, concentrating on the most recent phases of hominin evolution, the rise of Homo sapiens and the very earliest human societies through to the end of the last ice age. Anthropologists, archaeologists, historical linguists and historians examine climate and tools, language, and culture, as well as offering regional perspectives from across the world.
