Texte by Louis Braille, the french inventor of a method for use by the blind.The 1839 brochure, which was preceded 10-year before by a first version in braille language printed and another in plain language, completes the development of his invention and represents its culmination.

An inspiring picture-book biography of Louis Braille—a blind boy so determined to read that he invented his own alphabet. **Winner of a Schneider Family Book Award!** Louis Braille was just five years old when he lost his sight. He was a clever boy, determined to live like everyone else, and what he wanted more than anything was to be able to read. Even at the school for the blind in Paris, there were no books for him. And so he invented his own alphabet—a whole new system for writing that could be read by touch. A system so ingenious that it is still used by the blind community today. Award-winning writer Jen Bryant tells Braille’s inspiring story with a lively and accessible text, filled with the sounds, the smells, and the touch of Louis’s world. Boris Kulikov’s inspired paintings help readers to understand what Louis lost, and what he was determined to gain back through books. An author’s note and additional resources at the end of the book complement the simple story and offer more information for parents and teachers. Praise for Six Dots: "An inspiring look at a child inventor whose drive and intelligence changed to world—for the blind and sighted alike."—Kirkus Reviews "Even in a crowded field, Bryant’s tightly focused work, cast in the fictionalized voice of Braille himself, is particularly distinguished."—Bulletin, starred review "This picture book biography strikes a perfect balance between the seriousness of Braille’s life and the exuberance he projected out into the world." — School Library Journal, starred review

The definitive history of the societal forces affecting blind people in the United States and the professions that evolved to provide services to people who are visually impaired, The Unseen Minority was originally commissioned to commemorate the fiftieth anniversary of the American Foundation for the Blind in 1971. Updated with a new foreword outlining the critical issues that have arisen since the original publication and with time lines presenting the landmark events in the legislative arena, low vision, education, and orientation and mobility, this classic work has never been more relevant.

The integration of the blind into society has always meant taking on prejudices and inaccurate representations. Weygand's highly accessible anthropological and cultural history introduces us to both real and imaginary figures from the past, uncovering French attitudes towards the blind from the Middle Ages through the first half of the nineteenth century. Much of the book, however, centers on the eighteenth century, the enlightened age of Diderot's emblematic blind man and of the Institute for Blind Youth in Paris, founded by Valentin Haüy, the great benefactor of blind people. Weygand paints a moving picture of the blind admitted to the institutions created for them and of the conditions under which they lived, from the officially-sanctioned beggars of the medieval Quinze-Vingts to the cloth makers of the Institute for Blind Workers. She has also uncovered their fictional counterparts in an impressive array of poems, plays, and novels.The book concludes with Braille, whose invention of writing with raised dots gave blind people around the world definitive access to silent reading and to written communication.

Humans are an ingenious species. Though we've been on the planet for a relatively short amount of time (Earth is 4.5 billion years old); modern Homo sapiens have dreamed up and created some amazing; sometimes far-out; things. From the moment someone bashed a rock on the ground to make the first sharp-edged tool; to the debut of the wheel to the development of Mars rovers and the Internet; several key advancements stand out as particularly revolutionary. Here are our top picks for the most important inventions of all time; along with the science behind the invention and how they came about.

The classic guide to how computers work, updated with new chapters and interactive graphics "For me, Code was a revelation. It was the first book about programming that spoke to me. It started with a story, and it built up, layer by layer, analogy by analogy, until I understood not just the Code, but the System. Code is a book that is as much about Systems Thinking and abstractions as it is about code and programming. Code teaches us how many unseen layers there are between the computer systems that we as users look at every day and the magical silicon rocks that we infused with lightning and taught to think." - Scott Hanselman, Partner Program Director, Microsoft, and host of Hanselminutes Computers are everywhere, most obviously in our laptops and smartphones, but also our cars, televisions, microwave ovens, alarm clocks, robot vacuum cleaners, and other smart appliances. Have you ever wondered what goes on inside these devices to make our lives easier but occasionally more infuriating? For more than 20 years, readers have delighted in Charles Petzold's illuminating story of the secret inner life of computers, and now he has revised it for this new age of computing. Cleverly illustrated and easy to understand, this is the book that cracks the mystery. You'll discover what flashlights, black cats, seesaws, and the ride of Paul Revere can teach you about computing, and how human ingenuity and our compulsion to communicate have shaped every electronic device we use. This new expanded edition explores more deeply the bit-by-bit and gate-by-gate construction of the heart of every smart device, the central processing unit that combines the simplest of basic operations to perform the most complex of feats. Petzold's companion website, CodeHiddenLanguage.com, uses animated graphics of key circuits in the book to make computers even easier to comprehend. In addition to substantially revised and updated content, new chapters include: Chapter 18: Let's Build a Clock!
