The Oxford Illustrated History of Science by Iwan Rhys Morus Pdf
The Oxford Illustrated History of Science offers readers an accessible and entertaining introduction to the history of science as well as a valuable and authoritative reference work.
Everybody has one. It’s called a "haunt detector." It’s the little alarm that goes off in our heads whenever we detect that something mysterious or supernatural has occurred. You could be sitting around relaxing one day at home, and for no special reason you start thinking about someone. Maybe you haven’t thought about this person in years. Then the phone rings; you pick it up, and amazingly, it’s that person! Many of us have experienced this phenomenon. What is it? Anthony DeStefano answers this compelling question in his fascinating new book, The Invisible World. No matter how little we may understand or how fleeting such moments can be, he explains the reality of the spiritual dimension that surrounds us and shows how it is immediately accessible to everyone. All aspects of the spiritual realm are discussed, including the existence of angels and demons, the whereabouts of loved ones who have passed, and even the presence and activity of God in our lives. Written to be completely consistent with traditional Christian teaching, The Invisible World will help readers embrace a certitude that makes it easier to act according to their moral beliefs, give them a greater sense of the richness of life, and show them that no amount of suffering in their life—physical, mental, or emotional—will ever be able to destroy the profound sense of inner peace that can be experienced on a daily basis. For those seeking reassurance about meaning in their life, nothing is more significant than to be reminded that no one is alone. In The Invisible World, Anthony DeStefano shows the truth of this in a captivating and inspiring way.
Exploring the Invisible Universe by Belal Ehsan Baaquie,Frederick Hans Willeboordse Pdf
"Why"? Why is the world, the Universe the way it is? Is space infinitely large? How small is small? What happens when one continues to divide matter into ever smaller pieces? Indeed, what is matter? Is there anything else besides what can be seen? Pursuing the questions employing the leading notions of physics, one soon finds that the tangible and visible world dissolves -- rather unexpectedly -- into invisible things and domains that are beyond direct perception. A remarkable feature of our Universe is that most of its constituents turn out to be invisible, and this fact is brought out with great force by this book. Exploring the Invisible Universe covers the gamut of topics in advanced modern physics and provides extensive and well substantiated answers to these questions and many more. Discussed in a non-technical, yet also non-trivial manner, are topics dominated by invisible things -- such as Black Holes and Superstrings as well as Fields, Gravitation, the Standard Model, Cosmology, Relativity, the Origin of Elements, Stars and Planetary Evolution, and more. Just giving the answer, as so many books do, is really not telling anything at all. To truly answer the "why" questions of nature, one needs to follow the chain of reasoning that scientists have used to come to the conclusions they have. This book does not shy away from difficult-to-explain topics by reducing them to one-line answers and power phrases suitable for a popular talk show. The explanations are rigorous and straight to the point. This book is rarely mathematical without being afraid, however, to use elementary mathematics when called for. In order to achieve this, a large number of detailed figures, specially developed for this book and found nowhere else, convey insights that otherwise might either be inaccessible or need lengthy and difficult-to-follow explanations. After Exploring the Invisible Universe, a reader will have a deeper insight into our current understanding of the foundations of Nature and be able to answer all the questions above and then some. To understand Nature and the cutting edge ideas of contemporary physics, this is the book to have.
Time: A Bibliographic Guide by Samuel L. Macey Pdf
Originally published in 1991. A multidisciplinary guide in the form of a bibliography of selected time-related books and articles divided into 25 existing academic disciplines and about 100 subdisciplines which have a wide application to time studies.
The Oxford Companion to the History of Modern Science by John L. Heilbron Pdf
Containing 609 encyclopedic articles written by more than 200 prominent scholars, The Oxford Companion to the History of Modern Science presents an unparalleled history of the field invaluable to anyone with an interest in the technology, ideas, discoveries, and learned institutions that have shaped our world over the past five centuries. Focusing on the period from the Renaissance to the early twenty-first century, the articles cover all disciplines (Biology, Alchemy, Behaviorism), historical periods (the Scientific Revolution, World War II, the Cold War), concepts (Hypothesis, Space and Time, Ether), and methodologies and philosophies (Observation and Experiment, Darwinism). Coverage is international, tracing the spread of science from its traditional centers and explaining how the prevailing knowledge of non-Western societies has modified or contributed to the dominant global science as it is currently understood. Revealing the interplay between science and the wider culture, the Companion includes entries on topics such as minority groups, art, religion, and science's practical applications. One hundred biographies of the most iconic historic figures, chosen for their contributions to science and the interest of their lives, are also included. Above all The Oxford Companion to the History of Modern Science is a companion to world history: modern in coverage, generous in breadth, and cosmopolitan in scope. The volume's utility is enhanced by a thematic outline of the entire contents, a thorough system of cross-referencing, and a detailed index that enables the reader to follow a specific line of inquiry along various threads from multiple starting points. Each essay has numerous suggestions for further reading, all of which favor literature that is accessible to the general reader, and a bibliographical essay provides a general overview of the scholarship in the field. Lastly, as a contribution to the visual appeal of the Companion, over 100 black-and-white illustrations and an eight-page color section capture the eye and spark the imagination.
The Oxford Guide to the History of Physics and Astronomy by John L. Heilbron Pdf
With over 150 alphabetically arranged entries about key scientists, concepts, discoveries, technological innovations, and learned institutions, the Oxford Guide to Physics and Astronomy traces the history of physics and astronomy from the Renaissance to the present. For students, teachers, historians, scientists, and readers of popular science books such as Galileo's Daughter, this guide deciphers the methods and philosophies of physics and astronomy as well as the historical periods from which they emerged. Meant to serve the lay reader and the professional alike, this book can be turned to for the answer to how scientists learned to measure the speed of light, or consulted for neat, careful summaries of topics as complicated as quantum field theory and as vast as the universe. The entries, each written by a noted scholar and edited by J. L. Heilbron, Professor of History and Vice Chancellor, Emeritus, University of California, Berkeley, reflect the most up-to-date research and discuss the applications of the scientific disciplines to the wider world of religion, law, war, art and literature. No other source on these two branches of science is as informative or as inviting. Thoroughly cross-referenced and accented by dozens of black and white illustrations, the Oxford Guide to Physics and Astronomy is the source to turn to for anyone looking for a quick explanation of alchemy, x-rays and any type of matter or energy in between.
Space telescopes are among humankind’s greatest scientific achievements of the last fifty years. This book describes the instruments themselves and what they were designed to discover about the Solar System and distant stars. Exactly how these telescopes were built and launched and the data they provided is explored. Only certain kinds of radiation can penetrate our planet's atmosphere, which limits what we can observe. But with space telescopes all this changed. We now have the means to "see" beyond Earth using ultraviolet, microwave, and infrared rays, X-rays and gamma rays. In this book we meet the pioneers and the telescopes that were built around their ideas. This book looks at space telescopes not simply chronologically but also in order of the electromagnetic spectrum, making it possible to understand better why they were made.
The history of astronomy is, like most history, a multidimensional story, and when writing about a specific period, the author has to decide how to handle all the developments of earlier times in order to set the scene. I have done this by starting most chapters of the book with a summary of astronomical knowledge at the beginning of our chosen period, together with a brief review of how such knowledge had been gained. This story is not only interesting in itself, but it will also assist those readers that would appreciate a brief reminder of some of the basic elements of astronomy. It is also necessary to decide when to start our history. Should it be the year 1900 or 1890, or should it be linked to some key development or investigation, e. g. the discovery of the electron by J. J. Thomson in 1897, or the discovery of spectroscopic binary stars by Pickering and Vogel (independently) in 1889, or maybe the year 1890 in which Thomas Edison tried unsuccessfully to detect radio waves from the Sun and Johannes Rydberg published his formula for atomic spectra? I have, in fact, decided to start this history at about 1890, as it was the year of publication of the Draper Memorial Catalogue of stellar spectra which, together with its updates, provided essential data for the understanding of stellar spectra until well into the twentieth century. This date also gives a clear hundred years up to the present.
