"Everybody who has ever read a book will benefit from the way Keith Houston explores the most powerful object of our time. And everybody who has read it will agree that reports of the book’s death have been greatly exaggerated."— Erik Spiekermann, typographer We may love books, but do we know what lies behind them? In The Book, Keith Houston reveals that the paper, ink, thread, glue, and board from which a book is made tell as rich a story as the words on its pages—of civilizations, empires, human ingenuity, and madness. In an invitingly tactile history of this 2,000-year-old medium, Houston follows the development of writing, printing, the art of illustrations, and binding to show how we have moved from cuneiform tablets and papyrus scrolls to the hardcovers and paperbacks of today. Sure to delight book lovers of all stripes with its lush, full-color illustrations, The Book gives us the momentous and surprising history behind humanity’s most important—and universal—information technology.

A brilliantly brain-warping thriller and a love story that leaps back and forth in time – All Our Yesterdays is an amazing first novel, perfect for fans of The Hunger Games. Em is locked in a bare, cold cell with no comforts. Finn is in the cell next door. The Doctor is keeping them there until they tell him what he wants to know. Trouble is, what he wants to know hasn't happened yet. Em and Finn have a shared past, but no future unless they can find a way out. The present is torture – being kept apart, overhearing each other's anguish as the Doctor relentlessly seeks answers. There's no way back from here, to what they used to be, the world they used to know. Then Em finds a note in her cell which changes everything. It's from her future self and contains some simple but very clear instructions. Em must travel back in time to avert a tragedy that's about to unfold. Worse, she has to pursue and kill the boy she loves to change the future . . .

Explores the Jewish year with great depth, sensitivity, and insight. Laws, customs and practices are all noted and explained, along with the words of our Sages in a wealth of Midrashic commentary.

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.

Halloween, Valentine's Day, Christmas, Thanksgiving, New Year's Day - these are but a handful of modern holidays descended from the red-letter days, seasonal celebrations we have invented and reinvented over more than five millennia to meet our changing human needs. When we explore their origins, the holidays begin to reflect not only who we are but also why, through oppressed by time and thwarted by the forces of nature, we never seem to lose the will to control the future.

Sometimes the truths of the Bible can be obscured by the vast amount of information that the Bible contains. Our Book, with its brief summaries of all sixty-six books of the Bible and other essential reference material, sheds light on the context of God’s love and concern for His people. Our Book is sure to become a favorite resource for biblical study.

A BBC Sky at Night Best Astronomy and Space Book of the Year “[A] luminous guide to the cosmos...Jo Dunkley swoops from Earth to the observable limits, then explores stellar life cycles, dark matter, cosmic evolution and the soup-to-nuts history of the Universe.” —Nature “A grand tour of space and time, from our nearest planetary neighbors to the edge of the observable Universe...If you feel like refreshing your background knowledge...this little gem certainly won’t disappoint.” —Govert Schilling, BBC Sky at Night Most of us have heard of black holes and supernovas, galaxies and the Big Bang. But few understand more than the bare facts about the universe we call home. What is really out there? How did it all begin? Where are we going? Jo Dunkley begins in Earth’s neighborhood, explaining the nature of the Solar System, the stars in our night sky, and the Milky Way. She traces the evolution of the universe from the Big Bang fourteen billion years ago, past the birth of the Sun and our planets, to today and beyond. She then explains cutting-edge debates about such perplexing phenomena as the accelerating expansion of the universe and the possibility that our universe is only one of many. Our Universe conveys with authority and grace the thrill of scientific discovery and a contagious enthusiasm for the endless wonders of space-time.
