The Deepest Map: The High-Stakes Race to Chart the World's Oceans
Par Laura Trethewey. 2023
A Globe and Mail Top 100 SelectionFive oceans cover approximately seventy per cent of the earth, yet we know little…
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

“One of the best books I have read this year (maybe ever).” —Colby Sharp, Nerdy Book ClubNPR Books We Love…
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 ChanceMueller-Matrix Tomography of Biological Tissues and Fluids: Digital Image Processing and Analysis Techniques (SpringerBriefs in Applied Sciences and Technology)

biological layers. The promising and efficient use of vector-parametric description of the formation of polarization-inhomogeneous object fields is noted. Applications of a set of Mueller-matrix polarimetry methods are highlighted. The book includes- structural and logical scheme of multi-parameter (singular, interference and layer-by-layer Stokes-polarimetric), polarization-correlation study of the structure of distributions of the number of singularities, maps of local contrast of interference distributions and layer-by-layer maps of microscopic polarization azimuth and ellipticity; determination of relationships between changes in the magnitude of statistical parameters characterizing polarization-correlation distributions and pathology of prostate tumors.This thesis addresses the design of crystal structures using hydrogen bonds. In particular, it focuses on the design of functionalities…
and the control over the packing of molecular assemblies, based on molecular designs.Firstly, the synthesis and evaluation of a proton–electron mixed conducting charge transfer salt is reported. Focusing on the difference in the strength of hydrogen bonds and weaker intermolecular interactions, a system was rationally designed and constructed where electron-conducting molecular wires were encapsulated within a proton-conducting matrix. Next, the investigation of structural phase transitions in a cocrystal consisting of hydrogen-bonded two-dimensional molecular assemblies is reported. Drastic rearrangements of hydrogen-bonded molecular assemblies in the cocrystal led to single-crystal-to-single-crystal phase transitions, resulting in anisotropic changes in the crystal shape. Furthermore, chemical modification of a component molecule in the cocrystal is reported. The modification afforded control over the stacking patterns of the two-dimensional molecular assemblies, i.e., sheets, and the mechanism was discussed considering the intersheet intermolecular interactions and molecular motion.It is suggested that hydrogen bonds are beneficial to construct molecular assemblies in molecular crystals because of their strength and well-defined directionality, and the consideration of coexisting weaker intermolecular interactions can lead to the design of whole crystal structures and, hence, functionalities. This thesis benefits students and researchers working on solid-state chemistry by presenting various methods for characterizing and evaluating the properties of molecular solids.This book introduces a comprehensive framework tailored for dissecting complex systems across diverse disciplines.

can we harness information to quantify its order, structure, and intricacy? Delving into phenomena from the intricate processes in physical systems to the dynamic behaviours in cellular automata and pattern formation, readers will uncover the profound interplay between physics and information theory. This intricate relationship provides fresh insight into physical phenomena, reimagining them through the lens of information. Notably, the book demystifies how seemingly opposing forces—rising order and increasing disorder—coexist, ultimately shedding light on the second law of thermodynamics as an outcome of deterministic, reversible dynamics beneath the surface. Geared towards graduate students, this book presumes an undergraduate foundation in mathematics and physics, ensuring a deep, engaging exploration for its readers.Novel Optical Fiber Sensing Technology and Systems (Progress in Optical Science and Photonics #28)

Par Maxime Debertolis. 2024
This book presents a complete study of natural orbitals in quantum impurity problems, revealing a certain simplicity in these interacting…
many-body problems. These systems consist of a few localized degrees of freedom that undergo strong interactions and hybridize with a larger system of free particles; they are central in the study of strongly correlated systems. In a first step, the standard non-perturbative numerical renormalization group method is employed to demonstrate the hierarchical structure of correlations unveiled by natural orbitals. This simplification brought new insights for simulating quantum impurity problems, and a new algorithm is developed to generate an optimized subset of natural orbitals independently of existing methods, going beyond their usual limitations. This algorithm is presented in detail in the book, and a careful benchmark on known results is carried out to guarantee the validity of the method. It is then used to study spatial entanglement structures under various conditions that were not accessible with previous methods, such as representing the electron bath by a realistic 2D square lattice or taking account of static disorder in the metallic host. In the last chapter, the non-interacting problem in the presence of disorder is studied through random matrix theory, reproducing some of the results presented in the previous chapters. The main original result of this chapter lies in the analytical calculation of the joint distribution of one-particle orbitals energies and amplitudes of the impurity, which makes it possible to calculate any disordered averaged local correlation functions. Starting from this result, calculations in the large-N limit are compared with numerical simulations.Reef Smart Guides Grand Cayman (Reef Smart Guides)

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
Par Sun Kwok. 2023
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?

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 galaxies
