I walked on the moon. This is my journey. But it didn't begin when I stepped on board Apollo 11 on July 1, 1969. It began the day I was born. Becoming an astronaut took more than education, discipline, and physical strength. It took years of determination and believing that any goal is possible—from riding a bike alone across the George Washington Bridge at age ten to making a footprint on the Moon. I always knew the Moon was within my reach—and that I was ready to be on the team that would achieve the first landing. But it was still hard to believe when I took my first step onto the Moon's surface. We all have our own dreams. This is the story of how mine came true.
George and Tamsen Donner and their children, among the very first to leave from Illinois, joined emigrants headed to California in the spring of 1846. Beyond Fort Bridger, Captain Donner led a large party through a much-advertised shortcut. Delays and difficulties caused them to be snowbound in the High Sierras, facing the grim specter of starvation and extreme suffering. Though only four years old at the time of the expedition, the captain’s youngest daughter, Eliza Donner, would never forget the excitement of crossing the prairies—or the horror of that winter. Details impressed on her young mind were later substantiated by the recollections of her older sisters and other survivors. Her book, originally published in 1911, is an intimate and authoritative account of the Donner disaster. George and Tamsen Donner and those who shared their fate are fully humanized in the telling. Eliza also relates what happened to her and a sister after being rescued and what it was like to grow up in a world that turned the Donners into a grisly legend.
Are you constantly online? Or are you offline sometimes? Are you offline if you are not interacting with your connected devices? Or if no data about you is being collected? Do you check Instagram and Twitter during dinner? Do you turn off your smartphone at night? Do you check work emails on vacation? Do you feel you have to disconnect regularly – to relax, to concentrate, or to protect your privacy? Or do you feel more relaxed when constantly connected because your loved ones, a work emergency, or the news are always at your fingertips? Why are some people – even within networked societies – still completely offline given the tremendous opportunities of the Internet? And what does it even mean to be online or offline in the age of hyper-connectivity? In ON/OFF, Sarah Genner assesses the risks and rewards of the anytime-anywhere Internet, focusing on digital divides, social relationships, physical and mental health, and data privacy. She discusses implications for a variety of decision-makers in the world of work, in education, in families, and in politics. The author deconstructs the online/offline dichotomy and suggests the ON/OFF scale as a new theoretical framework for researchers and practitioners.

The life-long inventor, Lee de Forest invented the three-element vacuum tube used between 1906 and 1916 as a detector, amplifier, and oscillator of radio waves. Beginning in 1918 he began to develop a light valve, a device for writing and reading sound using light patterns. While he received many patents for his process, he was initially ignored by the film industry. In order to promote and demonstrate his process he made several hundred sound short films, he rented space for their showing; he sold the tickets and did the publicity to gain audiences for his invention. Lee de Forest officially brought sound to film in 1919. Lee De Forest: King of Radio, Television, and Film is about both invention and early film making; de Forest as the scientist and producer, director, and writer of the content. This book tells the story of de Forest’s contribution in changing the history of film through the incorporation of sound. The text includes primary source historical material, U.S. patents and richly-illustrated photos of Lee de Forest’s experiments. Readers will greatly benefit from an understanding of the transition from silent to audio motion pictures, the impact this had on the scientific community and the popular culture, as well as the economics of the entertainment industry.
