of what lies beneath them. Now, the race is on to completely map the oceans’ floor. Scientists, investors, militaries, and private explorers are competing in this epic venture to obtain an accurate reading of this vast terrain and understand its contours and environment. In The Deepest Map, Laura Trethewey chronicles this race to the bottom. Following global efforts around the world, she documents Inuit-led crowdsourced mapping in the Arctic as climate change alters the landscape, a Texas millionaire’s efforts to become the first man to dive to the deepest point in each ocean, and the increasingly fraught question of whether and how to mine the deep sea. A true tale of science, nature, technology, and extreme outdoor adventure, The Deepest Map both illuminates why we love — and fear — the earth’s final frontier and contributes to increasingly urgent conversations about climate change.The Probability of Everything

2023 | Publishers Weekly Best of 2023 | Winner of the Governor General's Literary Awards for Young People's LiteratureA heart-wrenching middle grade debut about Kemi, an aspiring scientist who loves statistics and facts, as she navigates grief and loss at a moment when life as she knows it changes forever.Eleven-year-old Kemi Carter loves scientific facts, specifically probability. It's how she understands the world and her place in it. Kemi knows her odds of being born were 1 in 5.5 trillion and that the odds of her having the best family ever were even lower. Yet somehow, Kemi lucked out.But everything Kemi thought she knew changes when she sees an asteroid hover in the sky, casting a purple haze over her world. Amplus-68 has an 84.7% chance of colliding with earth in four days, and with that collision, Kemi’s life as she knows it will end.But over the course of the four days, even facts don’t feel true to Kemi anymore. The new town she moved to that was supposed to be “better for her family” isn’t very welcoming. And Amplus-68 is taking over her life, but others are still going to school and eating at their favorite diner like nothing has changed. Is Kemi the only one who feels like the world is ending?With the days numbered, Kemi decides to put together a time capsule that will capture her family’s truth: how creative her mother is, how inquisitive her little sister can be, and how much Kemi's whole world revolves around her father. But no time capsule can change the truth behind all of it, that Kemi must face the most inevitable and hardest part of life: saying goodbye."My heart hurt as I raced through the last chapters of this unique book that shines a light on family, friends, grief, and love." —Lisa Yee, author of Maizy Chen's Last ChanceRick Steves Snapshot Kraków, Warsaw & Gdansk

Par Donald J. Robertson. 2019
Experience the world of Roman emperor Marcus Aurelius and the tremendous challenges he faced and overcame with the help of…
Stoic philosophy This novel biography brings Marcus Aurelius (121–180 CE) to life for a new generation of readers by exploring the emperor&’s fascinating psychological journey. Donald J. Robertson examines Marcus&’s relationships with key figures in his life, such as his mother, Domitia Lucilla, and the emperor Hadrian, as well as his Stoic tutors. He draws extensively on Marcus&’s own Meditations and correspondence, and he examines the emperor&’s actions as detailed in the Augustan History and other ancient texts. Marcus Aurelius struggled to reconcile his philosophy and moral values with the political pressures he faced as emperor at the height of Roman power. Robertson examines Marcus&’s attitude toward slavery and the moral dilemma posed by capturing enemies in warfare; his attitude toward women; the role of Stoicism in shaping his response to the threat of civil war; the treatment of Christians under his rule; and the naming of his notorious son Commodus as his successor. Throughout, the Meditations is used to shed light on the mind of the emperor—his character, values, and motives—as Robertson skillfully weaves together Marcus&’s inner journey as a philosopher with the outer events of his life as a Roman emperor.Data Science and Machine Learning Applications in Subsurface Engineering

problems. Processing voluminous and complex data sets are the primary focus of the field of machine learning (ML). ML aims to develop data-driven methods and computational algorithms that can learn to identify complex and non-linear patterns to understand and predict the relationships between variables by analysing extensive data. Although ML models provide the final output for predictions, several steps need to be performed to achieve accurate predictions. These steps, data pre-processing, feature selection, feature engineering and outlier removal, are all contained in this book. New models are also developed using existing ML architecture and learning theories to improve the performance of traditional ML models and handle small and big data without manual adjustments. This research-oriented book will help subsurface engineers, geophysicists, and geoscientists become familiar with data science and ML advances relevant to subsurface engineering. Additionally, it demonstrates the use of data-driven approaches for salt identification, seismic interpretation, estimating enhanced oil recovery factor, predicting pore fluid types, petrophysical property prediction, estimating pressure drop in pipelines, bubble point pressure prediction, enhancing drilling mud loss, smart well completion and synthetic well log predictions.A Woman in the Polar Night (Pushkin Press Classics)

the mesmerizingly beautiful account of one woman's year spent living in a remote hut in the ArcticThis rediscovered classic memoir tells the incredible tale of a woman defying society's expectations to find freedom and peace in the adventure of a lifetime.In 1934, the painter Christiane Ritter leaves her comfortable life in Austria and travels to the remote Arctic island of Spitsbergen, to spend a year there with her husband. She thinks it will be a relaxing trip, a chance to 'read thick books in the remote quiet and, not least, sleep to my heart's content', but when Christiane arrives she is shocked to realize that they are to live in a tiny ramshackle hut on the shores of a lonely fjord, hundreds of miles from the nearest settlement, battling the elements every day, just to survive.At first, Christiane is horrified by the freezing cold, the bleak landscape the lack of equipment and supplies... But as time passes, after encounters with bears and seals, long treks over the ice and months on end of perpetual night, she finds herself falling in love with the Arctic's harsh, otherworldly beauty, gaining a great sense of inner peace and a new appreciation for the sanctity of life.Unser Platz im Universum: Astronomie anhand alter Entdeckungen verstehen

Wenn Sie schon immer die Grundprinzipien der Astronomie und der Himmelsbewegungen verstehen wollten, sollten Sie dieses Buch lesen. Anhand von…
Bildern des Himmels, die von verschiedenen Orten der Erde aus beobachtet wurden, sowie von Zeichnungen alter astronomischer Methoden und Werkzeuge erzählt Prof. Sun Kwok diese Geschichte auf unterhaltsame und faszinierende Weise.Seit den Anfängen der menschlichen Zivilisation haben sich die Menschen Gedanken über die Struktur des Kosmos und unseren Platz im Universum gemacht. Vor mehr als 2.000 Jahren wussten unsere Vorfahren bereits, dass die Jahreszeiten ungleichmäßig verlaufen, dass die Erde frei im Raum schwebt, und dass es Sterne gibt, die sie nicht sehen können. Aus ihren Himmelsbeobachtungen schlossen sie, dass die Erde rund ist. Mit einfachen Werkzeugen und mathematischen Methoden bestimmten die Astronomen der Antike die Größe der Erde und des Mondes, die Entfernung zum Mond und die Länge der Monate und des Jahres genau.Mit einem raffinierten Gerät, der Armillarsphäre, konnten die griechischen Astronomen die Zeiten des Sonnenaufgangs und des Sonnenuntergangs an jedem Tag des Jahres und an jedem Ort der Erde vorhersagen. Sie entwickelten ausgeklügelte mathematische Modelle, um die Bewegungen des Mars für Hunderte von Jahren in die Zukunft vorauszusagen.Finden Sie heraus, wie die antiken Beobachter diese bemerkenswerten Leistungen vollbrachten. Mit minimalem Einsatz von Mathematik zeichnet dieses Buch die Spuren unserer Vorfahren nach, erklärt ihre intellektuelle Reise in einfachen Worten und erforscht die philosophischen Bedeutungen dieser Entdeckungen.This book presents a comprehensive overview of the sum rule approach to spectral analysis of orthogonal polynomials, which derives from…
Gábor Szego's classic 1915 theorem and its 1920 extension. Barry Simon emphasizes necessary and sufficient conditions, and provides mathematical background that until now has been available only in journals. Topics include background from the theory of meromorphic functions on hyperelliptic surfaces and the study of covering maps of the Riemann sphere with a finite number of slits removed. This allows for the first book-length treatment of orthogonal polynomials for measures supported on a finite number of intervals on the real line. In addition to the Szego and Killip-Simon theorems for orthogonal polynomials on the unit circle (OPUC) and orthogonal polynomials on the real line (OPRL), Simon covers Toda lattices, the moment problem, and Jacobi operators on the Bethe lattice. Recent work on applications of universality of the CD kernel to obtain detailed asymptotics on the fine structure of the zeros is also included. The book places special emphasis on OPRL, which makes it the essential companion volume to the author's earlier books on OPUC.How Did the First Stars and Galaxies Form? (Princeton Frontiers in Physics #1)
Par Abraham Loeb. 2010
A concise introduction to cosmology and how light first emerged in the universeThough astrophysicists have developed a theoretical framework for…
understanding how the first stars and galaxies formed, only now are we able to begin testing those theories with actual observations of the very distant, early universe. We are entering a new and exciting era of discovery that will advance the frontiers of knowledge, and this book couldn't be more timely. It covers all the basic concepts in cosmology, drawing on insights from an astronomer who has pioneered much of this research over the past two decades.Abraham Loeb starts from first principles, tracing the theoretical foundations of cosmology and carefully explaining the physics behind them. Topics include the gravitational growth of perturbations in an expanding universe, the abundance and properties of dark matter halos and galaxies, reionization, the observational methods used to detect the earliest galaxies and probe the diffuse gas between them—and much more.Cosmology seeks to solve the fundamental mystery of our cosmic origins. This book offers a succinct and accessible primer at a time when breathtaking technological advances promise a wealth of new observational data on the first stars and galaxies.Provides a concise introduction to cosmologyCovers all the basic conceptsGives an overview of the gravitational growth of perturbations in an expanding universeExplains the process of reionizationDescribes the observational methods used to detect the earliest galaxiesEinstein and Religion: Physics and Theology
Par Max Jammer. 1999
The philosophy of religion and the quest for spiritual truth preoccupied Albert Einstein--so much that it has been said "one…
might suspect he was a disguised theologian." Nevertheless, the literature on the life and work of Einstein, extensive as it is, does not provide an adequate account of his religious conception and sentiments. Only fragmentarily known, Einstein's ideas about religion have been often distorted both by atheists and by religious groups eager to claim him as one of their own. But what exactly was Einstein's religious credo? In this fascinating book, the distinguished physicist and philosopher Max Jammer offers an unbiased and well-documented answer to this question. The book begins with a discussion of Einstein's childhood religious education and the religious atmosphere--or its absence--among his family and friends. It then reconstructs, step by step, the intellectual development that led Einstein to the conceptions of a cosmic religion and an impersonal God, akin to "the God of Spinoza." Jammer explores Einstein's writings and lectures on religion and its role in society, and how far they have been accepted by the general public and by professional theologians like Paul Tillich or Frederick Ferré. He also analyzes the precise meaning of Einstein's famous dictum "Science without religion is lame, religion without science is blind," and why this statement can serve as an epitome of Einstein's philosophy of religion. The last chapter deals with the controversial question of whether Einstein's scientific work, and in particular his theory of relativity, has theologically significant implications, a problem important for those who are interested in the relation between science and religion. Both thought-provoking and engaging, this book aims to introduce readers, without proselytizing, to Einstein's religion.Mrs. Perkins's Electric Quilt: And Other Intriguing Stories of Mathematical Physics

theory? The answer is just one of the fascinating ways that best-selling popular math writer Paul Nahin illustrates the deep interplay of math and physics in the world around us in his latest book of challenging mathematical puzzles, Mrs. Perkins's Electric Quilt. With his trademark combination of intriguing mathematical problems and the historical anecdotes surrounding them, Nahin invites readers on an exciting and informative exploration of some of the many ways math and physics combine to create something vastly more powerful, useful, and interesting than either is by itself.In a series of brief and largely self-contained chapters, Nahin discusses a wide range of topics in which math and physics are mutually dependent and mutually illuminating, from Newtonian gravity and Newton's laws of mechanics to ballistics, air drag, and electricity. The mathematical subjects range from algebra, trigonometry, geometry, and calculus to differential equations, Fourier series, and theoretical and Monte Carlo probability. Each chapter includes problems—some three dozen in all—that challenge readers to try their hand at applying what they have learned. Just as in his other books of mathematical puzzles, Nahin discusses the historical background of each problem, gives many examples, includes MATLAB codes, and provides complete and detailed solutions at the end.Mrs. Perkins's Electric Quilt will appeal to students interested in new math and physics applications, teachers looking for unusual examples to use in class—and anyone who enjoys popular math books.Albert Einstein, The Human Side: Glimpses from His Archives

Einstein Archives. The illustrious physicist wrote as thoughtfully to an Ohio fifth-grader, distressed by her discovery that scientists classify humans as animals, as to a Colorado banker who asked whether Einstein believed in a personal God. Witty rhymes, an exchange with Queen Elizabeth of Belgium about fine music, and expressions of his devotion to Zionism are but some of the highlights found in this warm and enriching book.How to Build a Habitable Planet: The Story of Earth from the Big Bang to Humankind - Revised and Expanded Edition
Par Charles H. Langmuir, Wallace Broecker. 2012
A classic introduction to the story of Earth's origin and evolution—revised and expanded for the twenty-first centurySince its first publication…
more than twenty-five years ago, How to Build a Habitable Planet has established a legendary reputation as an accessible yet scientifically impeccable introduction to the origin and evolution of Earth, from the Big Bang through the rise of human civilization. This classic account of how our habitable planet was assembled from the stuff of stars introduced readers to planetary, Earth, and climate science by way of a fascinating narrative. Now this great book has been made even better. Harvard geochemist Charles Langmuir has worked closely with the original author, Wally Broecker, one of the world's leading Earth scientists, to revise and expand the book for a new generation of readers for whom active planetary stewardship is becoming imperative.Interweaving physics, astronomy, chemistry, geology, and biology, this sweeping account tells Earth’s complete story, from the synthesis of chemical elements in stars, to the formation of the Solar System, to the evolution of a habitable climate on Earth, to the origin of life and humankind. The book also addresses the search for other habitable worlds in the Milky Way and contemplates whether Earth will remain habitable as our influence on global climate grows. It concludes by considering the ways in which humankind can sustain Earth’s habitability and perhaps even participate in further planetary evolution.Like no other book, How to Build a Habitable Planet provides an understanding of Earth in its broadest context, as well as a greater appreciation of its possibly rare ability to sustain life over geologic time.Leading schools that have ordered, recommended for reading, or adopted this book for course use:Arizona State UniversityBrooklyn College CUNYColumbia UniversityCornell UniversityETH ZurichGeorgia Institute of TechnologyHarvard UniversityJohns Hopkins UniversityLuther CollegeNorthwestern UniversityOhio State UniversityOxford Brookes UniversityPan American UniversityRutgers UniversityState University of New York at BinghamtonTexas A&M UniversityTrinity College DublinUniversity of BristolUniversity of California-Los AngelesUniversity of CambridgeUniversity Of ChicagoUniversity of Colorado at BoulderUniversity of GlasgowUniversity of LeicesterUniversity of Maine, FarmingtonUniversity of MichiganUniversity of North Carolina at Chapel HillUniversity of North GeorgiaUniversity of NottinghamUniversity of OregonUniversity of OxfordUniversity of PortsmouthUniversity of SouthamptonUniversity of UlsterUniversity of VictoriaUniversity of WyomingWestern Kentucky UniversityYale UniversityElektrotechnik für Dummies.

Par Hermann Weyl. 2009
Hermann Weyl (1885-1955) was one of the twentieth century's most important mathematicians, as well as a seminal figure in the…
development of quantum physics and general relativity. He was also an eloquent writer with a lifelong interest in the philosophical implications of the startling new scientific developments with which he was so involved. Mind and Nature is a collection of Weyl's most important general writings on philosophy, mathematics, and physics, including pieces that have never before been published in any language or translated into English, or that have long been out of print. Complete with Peter Pesic's introduction, notes, and bibliography, these writings reveal an unjustly neglected dimension of a complex and fascinating thinker. In addition, the book includes more than twenty photographs of Weyl and his family and colleagues, many of which are previously unpublished. Included here are Weyl's exposition of his important synthesis of electromagnetism and gravitation, which Einstein at first hailed as "a first-class stroke of genius"; two little-known letters by Weyl and Einstein from 1922 that give their contrasting views on the philosophical implications of modern physics; and an essay on time that contains Weyl's argument that the past is never completed and the present is not a point. Also included are two book-length series of lectures, The Open World (1932) and Mind and Nature (1934), each a masterly exposition of Weyl's views on a range of topics from modern physics and mathematics. Finally, four retrospective essays from Weyl's last decade give his final thoughts on the interrelations among mathematics, philosophy, and physics, intertwined with reflections on the course of his rich life.Heart of Darkness: Unraveling the Mysteries of the Invisible Universe (Science Essentials #18)
Par Jeremiah P. Ostriker, Simon Mitton. 2013
Humanity's ongoing quest to unlock the secrets of dark matter and dark energyHeart of Darkness describes the incredible saga of…
humankind's quest to unravel the deepest secrets of the universe. Over the past forty years, scientists have learned that two little-understood components—dark matter and dark energy—comprise most of the known cosmos, explain the growth of all cosmic structure, and hold the key to the universe's fate. The story of how evidence for the so-called "Lambda-Cold Dark Matter" model of cosmology has been gathered by generations of scientists throughout the world is told here by one of the pioneers of the field, Jeremiah Ostriker, and his coauthor Simon Mitton.From humankind's early attempts to comprehend Earth's place in the solar system, to astronomers' exploration of the Milky Way galaxy and the realm of the nebulae beyond, to the detection of the primordial fluctuations of energy from which all subsequent structure developed, this book explains the physics and the history of how the current model of our universe arose and has passed every test hurled at it by the skeptics. Throughout this rich story, an essential theme is emphasized: how three aspects of rational inquiry—the application of direct measurement and observation, the introduction of mathematical modeling, and the requirement that hypotheses should be testable and verifiable—guide scientific progress and underpin our modern cosmological paradigm.This monumental puzzle is far from complete, however, as scientists confront the mysteries of the ultimate causes of cosmic structure formation and the real nature and origin of dark matter and dark energy.
