Advanced Methods of Joint Inversion and Fusion of Multiphysics Data (Advances in Geological Science)
Par Michael S. Zhdanov. 2023
Different physical or geophysical methods provide information about distinctive physical properties of the objects, e.g., rock formations and mineralization. In…
many cases, this information is mutually complementary, which makes it natural for consideration in a joint inversion of the multiphysics data. Inversion of the observed data for a particular experiment is subject to considerable uncertainty and ambiguity. One productive approach to reducing uncertainty is to invert several types of data jointly. Nonuniqueness can also be reduced by incorporating additional information derived from available a priori knowledge about the target to reduce the search space for the solution. This additional information can be incorporated in the form of a joint inversion of multiphysics data.Generally established joint inversion methods, however, are inadequate for incorporating typical physical or geological complexity. For example, analytic, empirical, or statistical correlations between different physical properties may exist for only part of the model, and their specific form may be unknown. Features or structures that are present in the data of one physical method may not be present in the data generated by another physical method or may not be equally resolvable.This book presents and illustrates several advanced, new approaches to joint inversion and data fusion, which do not require a priori knowledge of specific empirical or statistical relationships between the different model parameters or their attributes. These approaches include the following novel methods, among others: 1) the Gramian method, which enforces the correlation between different parameters; 2) joint total variation functional or joint focusing stabilizers, e.g., minimum support and minimum gradient support constraints; 3) data fusion employing a joint minimum entropy stabilizer, which yields the simplest multiphysics solution that fits the multi-modal data. In addition, the book describes the principles of using artificial intelligence (AI) in solving multiphysics inverse problems. The book also presents in detail both the mathematical principles of these advanced approaches to joint inversion of multiphysics data and successful case histories of regional-scale and deposit-scale geophysical studies to illustrate their indicated advantages.Familia Romana (Lingua Latina #Book One)
Par Hans H. Ørberg. 2011
Hans Ørberg's Lingua Latina per se Illustrata is the world's premiere series for learning Latin via the Natural Method. The…
Natural Method encourages students to learn Latin without resorting to translation, but instead by teaching them to think in the language: students first learn grammar and vocabulary inductively through extended contextual reading and an ingenious system of marginal notes. Lingua Latina per se Illustrata is also the most popular series for those teachers at both the secondary and collegiate levels who wish to develop Latin conversational skills in the classroom. Familia Romana (the main book of Pars I of the Lingua Latina per se illustrata series) contains thirty-five chapters and describes the life of a Roman family in the 2nd century A.D. It culminates in readings from classical poets and Donatus's Ars Grammatica, the standard Latin school text for a millennium. Each chapter is divided into two or three lessons (lectiones) of a few pages each followed by a grammar section (Grammatica Latina) and three exercises (Pensa). Hans Ørberg's impeccable Latin, humorous stories, and the Peer Lauritzen illustrations, reproduced in full color, make this work a classic. The book also includes a table of declensions, a Roman calendar, and a word index (index vocabulorum). The Lingua Latina series incorporates the following features: The most comprehensive treatment of Latin grammar available in an elementary textbook. A vocabulary of almost 1,800 words, reinforced by constant and creatively phrased repetition, vastly expands the potential for later sight reading. A complete line of ancillary volumes, exercises, and readers both in print and online.The Milky Way: An Autobiography of Our Galaxy
Par Moiya McTier. 2022
In this approachable and fascinating biography of the galaxy, an astrophysicist and folklorist details everything humans have discovered—from the Milky…
Way's formation to its eventual death, and what else there is to learn about the universe we call home. After a few billion years of bearing witness to life on Earth, of watching one hundred billion humans go about their day-to-day lives, of feeling unbelievably lonely, and of hearing its own story told by others, The Milky Way would like a chance to speak for itself. All one hundred billion stars and fifty undecillion tons of gas of it. It all began some thirteen billion years ago, when clouds of gas scattered through the universe's primordial plasma just could not keep their metaphorical hands off each other. They succumbed to their gravitational attraction, and the galaxy we know as the Milky Way was born. Since then, the galaxy has watched as dark energy pushed away its first friends, as humans mythologized its name and purpose, and as galactic archaeologists have worked to determine its true age (rude). The Milky Way has absorbed supermassive (an actual technical term) black holes, made enemies of a few galactic neighbors, and mourned the deaths of countless stars. Our home galaxy has even fallen in love. After all this time, the Milky Way finally feels that it's amassed enough experience for the juicy tell-all we've all been waiting for. Its fascinating autobiography recounts the history and future of the universe in accessible but scientific detail, presenting a summary of human astronomical knowledge thus far that is unquestionably out of this world. NAMED A BEST BOOK OF 2022 BY PUBLISHERS WEEKLY AND SCIENCENET NAMED A BEST AUDIOBOOK OF 2022 BY BOOKPAGEGiza: Acoustical Science and the Harvesting of Clean Energy
Par Christopher Dunn. 2024

enabled the harvesting of electricity and the mitigation of earthquakes• Shares recent cutting-edge research on earthquake lights, acoustic frequency measurements and energy concentration within the Great Pyramid, the shafts of the Queen&’s Chamber, the scorch marks that support the King&’s Chamber explosion hypothesis, and the significance of the large void above the Grand Gallery• Includes technical appendices written by experts and top researchersSharing extensive new evidence and cutting-edge research that the Great Pyramid at Giza was built as an energy-harvesting machine, Christopher Dunn details how the ancient Egyptians generated clean power for their civilization and reveals how the pyramid builders and the great inventor Nikola Tesla drew from the same universal knowledge. Looking at each part of the Great Pyramid, from the internal chambers to its massive stone blocks to the pyramidion on top, Dunn reveals how the pyramids in Egypt served to stimulate the release and collection of electrons in the Earth&’s crust by harmonizing seismic energy while also attenuating the accumulating stresses. Drawing on exhaustive ongoing research by NASA scientists into the phenomenon known as &“earthquake lights,&” Dunn shows how the pyramid builders were inspired by this phenomenon and learned to stress igneous rocks in order to harvest the resulting electron flow. He looks in depth at recent research that supports the pyramid energy theory, including new explorations of the shafts of the Queen&’s Chamber and analysis of the scorch marks on the ceiling of the Grand Gallery, which supports the King&’s Chamber explosion hypothesis. He examines the stunning significance of the large void above the Grand Gallery discovered in 2017. Dunn also analyses the results of extensive acoustic testing and measurements at ancient sacred sites and shows how the pyramids were tuned to the Earth&’s frequency. While the pyramids&’ sophisticated energy-harvesting abilities are now in disarray and disuse, some remnants of their technologies are still there, waiting to be rediscovered and provide our civilization with an abundance of nonpolluting power.Dendera, Temple of Time: The Celestial Wisdom of Ancient Egypt

by the author to reconstruct the complete ceiling of the portico of the Temple of Hathor at Dendera • Reveals in detail how each panel represents celestial cycles of time from the Precession of the Equinoxes to the annual cycles of life found along the Nile • Explains each panel&’s astronomical significance from the ancient Egyptian perspective as well as examining the myths, gods, and goddesses depicted Egypt is famous for its pyramids, the Sphinx, the temples at Luxor, and the Valley of the Kings, but 40 miles north of Luxor lies the best-preserved temple complex in all of Egypt: The Temple of Dendera, known for the famous &“Zodiac of Dendera&” now housed in the Louvre Museum. Within the portico leading into the Hathor temple at Dendera is a little-known outstanding achievement of humanity: an extensive colored bas-relief—larger than the ceiling of the Sistine Chapel—meticulously encoded with the sophisticated astronomical knowledge of ancient Egypt. Drawing on more than 5,000 high-resolution photographs he has taken at the Temple of Dendera, photographer and computer scientist José María Barrera presents a complete full-color photographic reconstruction of the ceiling of the pronaos at Dendera and reveals in detail how each panel represents celestial cycles of time from the Precession of the Equinoxes to the annual cycles of life found along the Nile. He explains the meaning of the layout of the ceiling as it relates to the present, the past, eternity, the hours of the day, the phases of the moon, the constellations used in ancient Egyptian astronomy, and the Great Solar Year. The author provides detailed analysis of each panel, including close-up photos, and explains each panel&’s astronomical and spiritual significance from the ancient Egyptian perspective as well as examining the myths, gods, and goddesses depicted. He also includes an appendix exploring the meaning and symbology of ancient Egyptian iconography. Allowing you to experience the vivid details of this ancient work of art and science, this photographic exploration also recreates the sense of spiritual awe and power the Temple of Dendera radiates to its visitors, whether today or millennia ago.Taking the Quantum Leap: The New Physics for Nonscientists
Par Fred A. Wolf. 1981
World renowned physicist Fred Alan Wolf explains the scientific concepts of quantum mechanics in accessible language for nonscientists.Winner of the…
National Book AwardTaking the Quantum Leap entertainingly traces the history of physics from the observations of the early Greeks through the discoveries of Galileo and Newton to the dazzling theories of such scientists as Planck, Einstein, Bohr, and Bohm. This humanized view of science opens up the mind-stretching visions of how quantum mechanics, God, human thought, and will are related, and provides profound implications for our understanding of the nature of reality and our relationship to the cosmos.“The prose, indeed, is exhilarating, and exhibits a passion to explain—humorously . . . Wolf provides commendable explanations of visions and revisions of atomic models; he is fin, in particular, on the Uncertainty Principle . . . Enjoy the book for its bravura.” —Kirkus ReviewsThis book focuses in detail on data science and data analysis and emphasizes the importance of data engineering and data…
management in the design of big data applications. The author uses patterns discovered in a collection of big data applications to provide design principles for hypothesis generation, integrating big data processing and management, machine learning and data mining techniques. The book proposes and explains innovative principles for interpreting hypotheses by integrating micro-explanations (those based on the explanation of analytical models and individual decisions within them) with macro-explanations (those based on applied processes and model generation). Practical case studies are used to demonstrate how hypothesis-generation and -interpretation technologies work. These are based on “social infrastructure” applications like in-bound tourism, disaster management, lunar and planetary exploration, and treatment of infectious diseases. The novel methods and technologies proposed in Hypothesis Generation and Interpretation are supported by the incorporation of historical perspectives on science and an emphasis on the origin and development of the ideas behind their design principles and patterns. Academic investigators and practitioners working on the further development and application of hypothesis generation and interpretation in big data computing, with backgrounds in data science and engineering, or the study of problem solving and scientific methods or who employ those ideas in fields like machine learning will find this book of considerable interest.Optical Fiber Current and Voltage Sensors (Series in Fiber Optic Sensors)

Par Simon Badger, Johannes Henn, Jan Christoph Plefka, Simone Zoia. 2024
This open access book bridges a gap between introductory Quantum Field Theory (QFT) courses and state-of-the-art research in scattering amplitudes.…
It covers the path from basic definitions of QFT to amplitudes, which are relevant for processes in the Standard Model of particle physics. The book begins with a concise yet self-contained introduction to QFT, including perturbative quantum gravity. It then presents modern methods for calculating scattering amplitudes, focusing on tree-level amplitudes, loop-level integrands and loop integration techniques. These methods help to reveal intriguing relations between gauge and gravity amplitudes and are of increasing importance for obtaining high-precision predictions for collider experiments, such as those at the Large Hadron Collider, as well as for foundational mathematical physics studies in QFT, including recent applications to gravitational wave physics.These course-tested lecture notes include numerous exercises with solutions. Requiring only minimal knowledge of QFT, they are well-suited for MSc and PhD students as a preparation for research projects in theoretical particle physics. They can be used as a one-semester graduate level course, or as a self-study guide for researchers interested in fundamental aspects of quantum field theory.The Goldilocks Enigma: Why Is the Universe Just Right for Life?
Par Paul Davies. 2007
An acclaimed physicist and cosmologist considers the multiverse and more: &“Very readable indeed . . . This is Doctor Who, but for real.&” —TheGuardianThe…
Goldilocks Enigma is Paul Davies&’s eagerly awaited return to cosmology, the successor to his critically acclaimed bestseller The Mind of God. Here he tackles all the &“big questions,&” including the biggest of them all: Why does the universe seem so well adapted for life? In his characteristically clear and elegant style, Davies shows how recent scientific discoveries point to a perplexing fact: many different aspects of the cosmos, from the properties of the humble carbon atom to the speed of light, seem tailor-made to produce life. A radical new theory says it&’s because our universe is just one of an infinite number of universes, each one slightly different. Our universe is bio-friendly by accident—we just happened to win the cosmic jackpot. While this &“multiverse&” theory is compelling, it has bizarre implications, such as the existence of infinite copies of each of us and Matrix-like simulated universes. And it still leaves a lot unexplained. Davies believes there&’s a more satisfying solution to the problem of existence: the observations we make today could help shape the nature of reality in the remote past. If this is true, then life—and, ultimately, consciousness—aren&’t just incidental byproducts of nature, but central players in the evolution of the universe. Whether he&’s elucidating dark matter or dark energy, M-theory or the multiverse, Davies brings the leading edge of science into sharp focus, provoking us to think about the cosmos and our place within it in new and thrilling ways.Survival Guide Wissenschaft: (Über-)Lebenstipps für akademische Karrieren

the Roman emperor Hadrian. The work can be examined from the perspective of the issues raised by writing Roman imperial biography at large and the many ways in which Mémoires has a claim to historical authenticity. In Marguerite Yourcenar’s Hadrian, Keith Bradley explains how Mémoires d’Hadrien came to be written, gives details of Yourcenar’s own biography, and describes some of the intricate historical problems that her novel’s portrait of Hadrian presents. He draws on Yourcenar’s correspondence, her interviews with journalists, and her literary corpus as a whole, emphasizing Yourcenar’s profound knowledge of the ancient evidence on which her life of Hadrian is based and exploiting a wide range of contemporary Yourcenarian criticism. The book pays special attention to the methods by which Yourcenar believed Hadrian’s life history to be recoverable, compares examples of modern life-writing, and contrasts the procedures of conventional Roman biographers. Revealing how and why Mémoires d’Hadrien is as it is, Marguerite Yourcenar’s Hadrian illustrates how imaginative literary recreation is often little different from historical speculation.Step into the world of Ancient Rome and explore the rise and fall of a fascinating ancient civilization like never…
