    Quackenbush (who teaches the Bates method in California and Oregon) describes how eyesight can improve naturally, at any age and regardless of heredity. This book is a wonderful tribute to the genius of Dr. Bates, who was a pioneer in discovering how vision becomes blurred and how it restores itself naturally to clarity and acuity. Now 80 years later, his findings and teachings remain light years ahead of our contemporaries. His approach to treating vision problems was truly holistic and the theme throughout this book is very much an extension of that holistic approach. Dr. Quackenbush is to be commended for his dedication in getting the truth out and keeping the torch burning in this "bible" on vision improvement.

     Five years after the brutal slaying of her husband, software executive Jill Shannon is ready to take the next step in her life. But with her wedding to prosecuting attorney Conner Manning just eight weeks away, her future father-in-law’s political ambitions for her fiancé threaten all her hopes. Jill’s past holds dark secrets. Secrets she can’t afford to have exposed under the relentless lights of a political campaign. When Phoenix Detective David Shaw turns up at Jill’s door asking questions about a reporter's murder, he has no idea what a lethal Pandora’s Box he’s just opened. Was the womanizing reporter killed by a jealous husband, or was it related to his drug use? Or did it have something to do with the secret expose the reporter was working on? Jill Shannon looks like a dead-end lead but Shaw can’t shake the feeling the beautiful widow has secrets she’s not sharing. Jill is caught between the sins of her past and the shattered hopes for her future. Shaw finds himself drawn deeper into a twisted labyrinth of lies and danger. One thing is clear: some vows are made out loud in front of witnesses. But some vows are made in silence, and witnesses can’t be left alive.

    Whether you’re deciding which smart phone to purchase or which politician to believe, you think you are a rational being whose every decision is based on cool, detached logic, but here’s the truth: You are not so smart. You’re just as deluded as the rest of us--but that’s okay, because being deluded is part of being human. Growing out of David McRaney’s popular blog, You Are Not So Smart reveals that every decision we make, every thought we contemplate, and every emotion we feel comes with a story we tell ourselves to explain them, but often these stories aren’t true. Each short chapter--covering topics such as Learned Helplessness, Selling Out, and the Illusion of Transparency--is like a psychology course with all the boring parts taken out.Bringing together popular science and psychology with humor and wit, You Are Not So Smart is a celebration of our irrational, thoroughly human behavior.

    A favorite of Tesla and SpaceX founder Elon Musk, listeners will want to tune into this "really good book on rocket[s]," available for the first time in audio. Ignition! is the story of the search for a rocket propellant which could be trusted to take man into space. This search was a hazardous enterprise carried out by rival labs who worked against the known laws of nature, with no guarantee of success or safety. Acclaimed scientist and sci-fi author John Drury Clark writes with irreverent and eyewitness immediacy about the development of the explosive fuels strong enough to negate the relentless restraints of gravity. The resulting volume is as much a memoir as a work of history, sharing a behind-the-scenes view of an enterprise that eventually took men to the moon, missiles to the planets, and satellites to outer space. A classic work in the history of science, listeners will want to get their hands on this influential classic, available for the first time in decades.
