Book Description
A series of photos taken from space more than 20 years ago revealed thousands of unknown galaxies in a tiny patch of _emptyî space. Called the Hubble Deep Field, the amazing image is made up of hundreds of photos combined into one. It was taken over the course of 10 days from the Hubble Space Telescope and has prompted astronomers and other scientists to speculate about universe�s size, shape, and age. How long ago did the first galaxies appear? Have they always looked like they do today, or have their shapes evolved over time? And will they, along with the universe itself, go on expanding forever? The Hubble Deep Field has helped to answer some of these questions.

Book Description
"Hubble Deep Field and the Distant Universe describes a watershed event in the history of astronomy, in addition to recounting the development of space astronomy. Aimed at a wide-ranging audience including amateur astronomers, science historians, researchers, Hubble Space Telescope (HST) aficionados and students interested in science, this book recounts the progression of events that led to the deep field exploration of Robert Williams and the Hubble Deep Field (HDF) team. Giving a fascinating insight into the processes by which astronomical research projects are carried out and unique discoveries are made by HST, this book describes the momentous image that has enabled astronomers to piece together the evolution of the largest structures in the universe."--Source : résumé de l'éditeur.

Book Description
The Hubble Deep Field (HDF) is the deepest optical image of the Universe ever obtained. It is the result of a 150-orbit observing programme with the Hubble Space Telescope. It provides a unique resource for researchers studying the formation and evolution of stars and galaxies. This timely volume provides the first comprehensive overview of the HDF and its scientific impact on our understanding in cosmology. It presents articles by a host of world experts who gathered together at an international conference at the Space Telescope Science Institute. The contributions combine observations of the HDF at a variety of wavelengths with the latest theoretical progress in our understanding of the cosmic history of star and galaxy formation. The HDF is set to revolutionize our understanding in cosmology. This book therefore provides an indispensable reference for all graduate students and researchers in observational or theoretical cosmology.

Book Description
Come join the fun as students take a submarine bus on a field trip to explore the ocean deep, in this wordless picture book from the creator of Field Trip to the Moon! Students dressed in deep sea helmets travel to the ocean deep in a yellow school-bus submarine. When they get there, they frolic with fish, chase luminescent squid, and discover an old shipwreck. But when it's time to return to the submarine bus, one student lingers to take a photo of a treasure chest and falls into a deep ravine. Luckily, the child makes an unexpected friend-- a maybe-not-so-extinct sea creature called a Pleiosaur- that's happy to entertain the young explorer until the teacher returns. In his follow-up to Field Trip to the Moon, John Hare's rich, atmospheric art in this wordless picture book invites all children to imagine themselves in the story- a tale full of mysteries, surprises, and adorable aquatic friends.

Book Description
This book is a synopsis of modern deep-field astronomy, based on the powerful telescopes and instruments developed in recent years. It is organized along topical themes, such as the extragalactic background radiation at different wavelengths, the evolution of galaxies, the history of star formation, the nature of absorbers, the reionization of the intergalactic medium, the validity of photometric redshifts, gravitational lensing, and clustering of galaxies. Stellar and substellar objects were not neglected, however, and one session was devoted to nearby bodies such as trans-Neptunian solar system objects, brown dwarfs, and stars with special characteristics.

Book Description
An introduction to a broad range of topics in deep learning, covering mathematical and conceptual background, deep learning techniques used in industry, and research perspectives. “Written by three experts in the field, Deep Learning is the only comprehensive book on the subject.” —Elon Musk, cochair of OpenAI; cofounder and CEO of Tesla and SpaceX Deep learning is a form of machine learning that enables computers to learn from experience and understand the world in terms of a hierarchy of concepts. Because the computer gathers knowledge from experience, there is no need for a human computer operator to formally specify all the knowledge that the computer needs. The hierarchy of concepts allows the computer to learn complicated concepts by building them out of simpler ones; a graph of these hierarchies would be many layers deep. This book introduces a broad range of topics in deep learning. The text offers mathematical and conceptual background, covering relevant concepts in linear algebra, probability theory and information theory, numerical computation, and machine learning. It describes deep learning techniques used by practitioners in industry, including deep feedforward networks, regularization, optimization algorithms, convolutional networks, sequence modeling, and practical methodology; and it surveys such applications as natural language processing, speech recognition, computer vision, online recommendation systems, bioinformatics, and videogames. Finally, the book offers research perspectives, covering such theoretical topics as linear factor models, autoencoders, representation learning, structured probabilistic models, Monte Carlo methods, the partition function, approximate inference, and deep generative models. Deep Learning can be used by undergraduate or graduate students planning careers in either industry or research, and by software engineers who want to begin using deep learning in their products or platforms. A website offers supplementary material for both readers and instructors.

Book Description
Set between Hong Kong and Sydney at the beginning of the next century, this is a novel about time, blindness and chaos, played out against the backdrop of a world poised on the brink of total collapse. Anna, a photographer, becomes interested in fossils and their preservation of form across geological time. She encounters Seth, a blind palaeontologist, whose very different sensory world leads her to new departures in her work. Anna and Seth gradually admit each other into their very private worlds. But Anna's involvement with Seth's sister and her anti-government protests is ultimately to have tragic consequences.

Book Description
The high-redshift galaxies became a distinct research ?eld during the ?nal decade of the20thcentury. AtthattimetheLyman-breaktechniquemadeitpossibletoidentify signi?cant samples of such objects, and the new generation of 8 to 10-m telescopes resulted in ?rst good spectroscopic data. Today the high-redshift galaxies have developed into one of the important topics of astrophysics, accounting for about 5–10% of the publications in the major scienti?c journals devoted to astronomy. Because high-redshift galaxies is a rapidly developing ?eld and since new results are published constantly, writing a book on this topic is challenging. On the other hand, in view of the large amount of individual results now in the literature, and in view of the still growing interest in this topic, it appears worthwhile to summarize and evaluate the available data and to provide an introduction for those who wish to enter this ?eld, or who, for various reasons, might be interested in its results. The end of the ?rst decade of the 21st century appears to be a good point in time to attempt such a summary. The current generation of ground-based 8 to 10-m - optical telescopes, the Hubble Space Telescope, and the most important large radio telescopes have by now been in operation since about one or two decades. Although these instruments will continue to produce important scienti?c results for some time to come, many of the initial programs exploiting their unique new possibilities have been completed.

Deeply thought and felt poems that reach into the gulf, to recover histories spoken and unspoken; an excavation of the spoken word itself.
