Greene, who recently launched World Science U, which offers free online science courses, explains what it is that's so "elegant" about string theory while lamenting the possible limits of what dogs (and by implication humans) can ever hope to understand about the universe. The interview was conducted by Rivka Galchen, an acclaimed fiction writer and journalist, named by The New Yorker as one of 20 Writers Under 40. Cover design by Adil Dara Kim.

    It was a sea in name only. It was actually a bone dry, ancient dusty basin pockmarked with craters and littered with rocks and boulders. Somewhere in that 500 mile diameter basin, the astronauts would attempt to make Mankind’s first landing on the Moon. Neil Armstrong would pilot the Lunar Module “Eagle” during its twelve minute descent from orbit down to a landing. Col. Edwin “Buzz” Aldrin would assist him. On the way down they would encounter a host of problems, any one of which could have potentially caused them to have to call off the landing, or, even worse, die making the attempt. The problems were all technical-communications problems, computer problems, guidance problems, sensor problems. Armstrong and Aldrin faced the very real risk of dying by the very same technical sword that they had to live by in order to accomplish the enormous task of landing on the Moon for the first time. Yet the human skills Armstrong and Aldrin employed would be more than equal to the task. Armstrong’s formidable skills as an aviator, honed from the time he was a young boy, would serve him well as he piloted Eagle down amidst a continuing series of systems problems that might have fatally distracted a lesser aviator. Armstrong’s brilliant piloting was complemented by Aldrin’s equally remarkable discipline and calmness as he stoically provided a running commentary on altitude and descent rate while handling systems problems that threatened the landing. Finally, after a harrowing twelve and a half minutes, Armstrong gently landed Eagle at “Tranquility Base”, a name he had personally chosen to denote the location of the first Moon landing. In “Landing Eagle-Inside the Cockpit During the First Moon Landing”, author Mike Engle gives a minute by minute account of the events that occurred throughout Eagle’s descent and landing on the Moon. Engle, a retired NASA engineer and Mission Control flight controller, uses NASA audio files of actual voice recordings made inside Eagle’s cockpit during landing to give the reader an “inside the cockpit” perspective on the first Moon landing. Engle’s transcripts of these recordings, along with background material on the history and technical details behind the enormous effort to accomplish the first Moon landing, give a new and fascinating insight into the events that occurred on that remarkable day fifty years ago.

    Richard Gott was among the first cosmologists to propose that the structure of our universe is like a sponge made up of clusters of galaxies intricately connected by filaments of galaxies—a magnificent structure now called the "cosmic web" and mapped extensively by teams of astronomers. Here is his gripping insider's account of how a generation of undaunted theorists and observers solved the mystery of the architecture of our cosmos.The Cosmic Web begins with modern pioneers of extragalactic astronomy, such as Edwin Hubble and Fritz Zwicky. It goes on to describe how, during the Cold War, the American school of cosmology favored a model of the universe where galaxies resided in isolated clusters, whereas the Soviet school favored a honeycomb pattern of galaxies punctuated by giant, isolated voids. Gott tells the stories of how his own path to a solution began with a high-school science project when he was eighteen, and how he and astronomer Mario Jurič measured the Sloan Great Wall of Galaxies, a filament of galaxies that, at 1.37 billion light-years in length, is one of the largest structures in the universe.Drawing on Gott’s own experiences working at the frontiers of science with many of today’s leading cosmologists, The Cosmic Web shows how ambitious telescope surveys such as the Sloan Digital Sky Survey are transforming our understanding of the cosmos, and how the cosmic web holds vital clues to the origins of the universe and the next trillion years that lie ahead.

    Off-grid locations can range from private islands to yurts and tree-houses; the people living there might be back-packers, right wing survivalists, international business travellers or hippies; they may move around in buses or yachts, houseboats or 4-wheel drives. All are outside or in between the criss-crossing lines of power, water and phone that delineate the civilized world. Some are trying to save the planet, some live that way because it is all they can afford, some just want the freedom.This book is about that physical sense of off-grid. But it is also about taking the off-grid attitude into your local park or your own back garden. It is part travellogue as Nick Rosen, his wife and baby take off in a camper van to visit off-gridders representing every aspect of living off-grid, both part-time or permanent. And it is also a guide to avoiding the pitfalls and finding the best solutions - and the most appealing gadgetry - for going off-grid yourself.

    (It was the heyday of Boss Tweed in New York.) But the Brooklyn Bridge was at once the greatest engineering triumph of the age, a surpassing work of art, a proud American icon, and a story like no other in our history. Courage, chicanery, unprecedented ingenuity and plain blundering, heroes, rascals, all the best and worst in human nature played a part. At the center of the drama were the stricken chief engineer, Washington Roebling and his remarkable wife, Emily Warren Roebling, neither of whom ever gave up in the face of one heartbreaking setback after another. The Great Bridge is a sweeping narrative of a stupendous American achievement that rose up out of its era like a cathedral, a symbol of affirmation then and still in our time.

    

    It offers complete coverage of the basics of hematologic morphology, including examination of the peripheral blood smear, basic maturation of the blood cell lines, and discussions of a variety of clinical disorders.

    This project turned into a quest to discover the secrets of the neighborhood’s flora and fauna, and yielded more than names and trivia: Johnson developed a relationship with his nonhuman neighbors.Johnson argues that learning to see the world afresh, like a child, shifts the way we think about nature: Instead of something distant and abstract, nature becomes real—all at once comical, annoying, and beautiful. This shift can add tremendous value to our lives, and it might just be the first step in saving the world.No matter where we live—city, country, oceanside, ormountains—there are wonders that we walk past every day. Unseen City widens the pinhole of our perspective by allowing us to view the world from the high-altitude eyes of a turkey vulture and the distinctly low-altitude eyes of a snail. The narrative allows us to eavesdrop on the comically frenetic life of a squirrel and peer deep into the past with a ginkgo biloba tree. Each of these organisms has something unique to tell us about our neighborhoods and, chapter by chapter, Unseen City takes us on a journey that is part nature lesson and part love letter to the world’s urban jungles. With the right perspective, a walk to the subway can be every bit as entrancing as a walk through a national park.

    

    From the mid-nineteenth century to the early twentieth, over 250 institutions for the insane were built throughout the United States; by 1948, they housed more than a half million patients. The blueprint for these hospitals was set by Pennsylvania hospital superintendent Thomas Story Kirkbride: a central administration building flanked symmetrically by pavilions and surrounded by lavish grounds with pastoral vistas. Kirkbride and others believed that well-designed buildings and grounds, a peaceful environment, a regimen of fresh air, and places for work, exercise, and cultural activities would heal mental illness. But in the second half of the twentieth century, after the introduction of psychotropic drugs and policy shifts toward community-based care, patient populations declined dramatically, leaving many of these beautiful, massive buildings--and the patients who lived in them--neglected and abandoned. Architect and photographer Christopher Payne spent six years documenting the decay of state mental hospitals like these, visiting seventy institutions in thirty states. Through his lens we see splendid, palatial exteriors (some designed by such prominent architects as H. H. Richardson and Samuel Sloan) and crumbling interiors--chairs stacked against walls with peeling paint in a grand hallway; brightly colored toothbrushes still hanging on a rack; stacks of suitcases, never packed for the trip home. Accompanying Payne's striking and powerful photographs is an essay by Oliver Sacks (who described his own experience working at a state mental hospital in his book Awakenings). Sacks pays tribute to Payne's photographs and to the lives once lived in these places, "where one could be both mad and safe."
