  Echoes of the Cosmos - Tracing...

  The universe is vast, filled with mysteries that challenge our understanding of reality. Among these, dark matter stands out as one of the most elusive and significant components of the cosmos. It is an invisible force that cannot be seen directly, yet it exerts a profound influence on the structure and behavior of galaxies, stars, and the universe as a whole. This chapter delves into the concept of dark matter, exploring its nature, how it was first theorized, and why it remains one of the most intriguing puzzles in modern physics and astronomy. 
  Dark matter was first proposed as a solution to an anomaly in the way galaxies rotate. In the 1930s, astronomer Fritz Zwicky observed that galaxies in the Coma Cluster were moving much faster than expected, based on the visible matter in those galaxies. He suggested the existence of an unseen mass, which he called "dark matter," to account for the gravitational pull that would explain these high speeds. This groundbreaking idea, however, was met with skepticism at the time. Over the decades that followed, evidence continued to accumulate, pointing to the presence of dark matter in the universe. 
  Dark matter is not something we can detect with traditional instruments because it does not emit, absorb, or reflect light. It is essentially invisible to electromagnetic radiation, which makes it very different from the ordinary matter that makes up stars, planets, and everything we can see in the universe. Despite its invisibility, dark matter’s presence is inferred through its gravitational effects on visible matter. For example, when we observe the rotation of galaxies, the stars at the outer edges are moving faster than they should, based on the amount of visible matter in the galaxy. This suggests that there is additional mass, unseen but detectable through its gravitational pull, holding these galaxies together.

  Next Generation Innovation -...

  The United States has a long history as a leader of global innovation and of funding pioneering technologies that prove to be of benefit to the nation. The present moment is no exception. In fact, the next decade is likely to see increased involvement from the Federal government bringing to market the most innovative technologies under development. Author Kelly Carnes identifies the current moment as a golden age of opportunity for American innovators to partner with government, a moment in which there is bipartisan support for investing more aggressively in the development and deployment of leading-edge technology.Next Generation Innovation collects insights from Carnes’ experience as an attorney for technology companies, her time spent working as Assistant Secretary of Commerce for Technology in the Office of Technology Policy, and her current entrepreneurial effort, TechVision21—a company offering exclusive assistance to technology visionaries interested in doing well by doing good for the nation. TechVision21 offers its clients the opportunity to collaborate with an expert team that is deeply knowledgeable about theories and models of innovation, the history of science and technology policy, and the details of U.S. government programs and budget-making processes.Carnes’ wide-ranging experience makes her uniquely sensitive to the challenges facing entrepreneurs taking ideas and projects from inception to commercialization. With full awareness of those challenges, Carnes argues that technology organizations of all sizes and capabilities could be doing more to leverage U.S. government policies, programs, and funding opportunities to achieve their fullest potential. She writes, “In my company’s work helping innovators establish and sustain productive relationships with the Federal government, I try never to lose sight of two important details: the government wants to support projects that serve the national good—whether promoting security, health, a clean environment, ensuring a stable and safe food supply, promoting high quality job opportunities, or addressing climate change—and many innovators are driven by a desire to contribute to the national or global good. …From the long-term partnerships between government and industry that I have both participated in and witnessed, doing good is the truest satisfaction drawn by both partners.”Next Generation Innovation sets as its task not only encouraging more entrepreneurs to consider the value of their ideas for promoting the national good but also guiding readers through a careful consideration of every step in the partnering process—from evaluating the partnership appropriateness of specific projects to setting priorities and developing a strategy that maximizes opportunity over the long term. In so doing, Carnes highlights the value of ongoing engagement with both program managers and policy makers as critical parts of any effort to promote one’s technology and achieve business goals.There is much to consider and much to do when it comes to engaging in fruitful long-term relationships with the Federal government. Carnes couches her down-to-earth, detailed practical advice within an overall approach that recognizes the significant amount of effort and know-how involved: “I emphasize the importance of finding early on people to integrate into your team who can take you all the way through that journey—from initial research and strategizing to plotting effective communications across a variety of audiences, to finding ways of further enhancing successful, established partnerships.”In response to the need for strategic, concerted effort, Next Generation Innovation can be read both as a primer for companies newly considering establishing government partnerships and as a timely reference for those looking to refresh and renew their approach.

  “A lovely balance of memoir, travelogue and olive-growing how-to . . . Some of her adventures are quite funny.” —Publishers Weekly In this memoir, the author of The Olive Farm returns to the ten-acre property for which she and her fiancé scraped together their savings to buy—just back from their wedding on a tiny Polynesian island, loaded down with luggage and a large hand-painted didgeridoo. As Carol and Michel settle in as husband and wife, they experience the glamor of southern France at dinner parties in the company of aristocrats and at the world-renowned Cannes film festival, as well as the dirt-caked, sun-baked life of farmers—especially after their gardener heads to Algiers to arrange his youngest son’s wedding. For Carol, though, what matters most is that her longtime dream of motherhood finally promises to come true—and over the course of The Olive Season, she shares the story of her hopes and fears as she anticipates another kind of growth and nurturing. Alternately entertaining and emotionally poignant, this memoir is a rich portrait of love, longing, and the constant uncertainties of the cycle of life.

  Son of Apollo - The Adventures...

  Christopher A. Roosa grew up the eldest son of Apollo 14 astronaut and command module pilot Stuart A. Roosa. As a child of the space program, Christopher had a ringside seat at the dinner table of one of twenty-four Americans who had either entered lunar orbit or landed on the moon. The first book written by an offspring of an Apollo astronaut to focus on growing up in that era, Son of Apollo tells the inside story of the life of his father, a man who had a remarkable career despite always believing his air force career was "off-track," from his initial application to the service to his removal from the prime crew of Apollo 13 and his subsequent assignment to Apollo 14. During the Apollo 13 mission and recovery, Stuart played an integral role in developing the procedures to return the crew to Earth safely. The focus—and the pressure—of the entire Apollo program then shifted to the Apollo 14 mission. If the Apollo program was to continue, Stuart and the Apollo 14 crew would need to get safely to the moon, land, and return. 
   
   
   
  In writing about his father's career, Christopher Roosa also shows us a familial side of the Apollo experience, from the daily struggles of growing up in the shadow of a father who was necessarily away in training most of the year to the expectations involved in being an astronaut's son.
