Dr. Dave Williams Bücher

"An inspirational, uplifting, and life-affirming memoir about passion, resilience and living life to the fullest, from Dr. Dave Williams, one of Canada's most accomplished astronauts ... In Defying Limits, Dave shares the events that have defined his life, showing us that whether we're gravity-defying astronauts or earth-bound terrestrials, we can all live an infinite, fulfilled life by relishing the value and importance of each moment. The greatest fear that we all face is not the fear of dying, but the fear of never having lived. Each of us is greater than we believe. And, together, we can exceed our limits to soar farther and higher than we ever imagined."--Amazon.com

This book explores the personalities, leadership styles, and decision-making of the NASA senior executives in the first decade of spaceflight and follows how those individuals created a culture that can take on seemingly insurmountable challenges, that can recover from tragedy and adversity, that continues to attract the best and brightest.

"What happens in space that causes the body to change? Learn about life in space from astronauts Is the human body built for Mars? NASA's studies on the International Space Station show we need to fix a few things before sending people to the Red Planet. Astronauts go into space with good vision and come back needing eyeglasses. Cognition and DNA expression could be affected for years. And then there's the discomfort of living in a tight space with crewmates, depression, and separation from the people you love. Space doctors are on the case. You'll meet the first twin to spend a year in space, the woman who racked up three physically challenging spacewalks in between 320 days of confinement, and the cosmonaut who was temporarily stranded on space station Mir while the Soviet Union broke up underneath him. What are we learning about the human body? As astronauts target moon missions and eventual landings on Mars, one of the major questions is how the human body will behave in "partial gravity." How does the human body change on another world, as opposed to floating freely in microgravity? What can studies on Earth and in space tell us about planetary exploration? These questions will be important to the future of space exploration and to related studies of seniors and people with reduced mobility on Earth."-- Provided by publisher

This book is a collection designed to gather together, for the first time, a conceptually wide and historically deep array of primary texts which demonstrate Euroamerican attitudes toward the Chinese. Among the many cultural artifacts generated by this encounter were plays written by Euroamericans which contained one or more representations of the Chinese. It would be reductive to say that such portrayals show merely the racism of a dominant culture toward a distinctive and different minority. Racism is of course present, sometimes of the coarsest and crudest sort; but other themes appear in the many dramatic portrayals of the Chinese as well, such as toleration, exoticism, and even idealization. The book is intended for scholars, graduate students and undergraduate students in the field of theatre, cultural studies, nineteenth-century studies, and Asian-American studies.

Really “high” tech to inspire us for sustainable solutions on Earth. Who could imagine an idea born on a space station would help sustain our planet? Astronauts, living on the International Space Station, have to protect their resources because their lives depend on it. They learn to conserve water, air, food, energy, and waste. These efforts have in turn lead to amazing and innovative ideas for air quality, food production, and water purification here on Earth. With vivid, energetic illustrations, photographs, and Dr. Dave’s experiments on key topics, readers learn about technological innovations such as waterless toilets and the world’s tallest air purification tower.
