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
From the authors of "How to Find the Apollo Landing Sites," this is a guide to connecting the view above with the history of recent scientific discoveries from the Hubble Space Telescope. Each selected HST photo is shown with a sky map and a photograph or drawing to illustrate where to find it and how it should appear from a backyard telescope. Here is the casual observer's chance to locate the deep space objects visually, and appreciate the historic Hubble photos in comparison to what is visible from a backyard telescope. HST objects of all types are addressed, from Messier objects, Caldwell objects, and NGC objects, and are arranged in terms of what can be seen during the seasons. Additionally, the reader is given an historical perspective on the work of Edwin Hubble, while locating and viewing the deep space objects that changed astronomy forever. Countless people have seen the amazing photographs taken by the Hubble Space Telescope. But how many people can actually point out where in the sky those objects are? Why were these objects chosen to be studied? What discoveries were made from the Hubble Space Telescope photographs? This book is for anyone who wants answers to these questions.

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
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
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
The Hubble Space Telescope (HST) has operated continuously since 1990. During that time, four space shuttle-based service missions were launched, three of which added major observational capabilities. A fifth â€" SM-4 â€" was intended to replace key telescope systems and install two new instruments. The loss of the space shuttle Columbia, however, resulted in a decision by NASA not to pursue the SM-4 mission leading to a likely end of Hubble's useful life in 2007-2008. This situation resulted in an unprecedented outcry from scientists and the public. As a result, NASA began to explore and develop a robotic servicing mission; and Congress directed NASA to request a study from the National Research Council (NRC) of the robotic and shuttle servicing options for extending the life of Hubble. This report presents an assessment of those two options. It provides an examination of the contributions made by Hubble and those likely as the result of a servicing mission, and a comparative analysis of the potential risk of the two options for servicing Hubble. The study concludes that the Shuttle option would be the most effective one for prolonging Hubble's productive life.
