"Far from being a lifeless ornament in the sky, the Moon holds the answers to some of science's central questions. Silent, dry, and barren, Earth's 4.34-billion-year-old companion is essential to life on earth. Its gravity stabilized the Earth's orbit, and, as it once guided evolution, its tide stirring up nutrients that fostered complex life, it now influences everything from animal migrations and reproduction to the movements of plants' leaves. More than 30,000 years before humans invented writing, they used the Moon's waxing and waning to track the passage of time, and, in a tectonic shift for human consciousness, used it to plan for the future. Unsurprisingly, the Moon was a primary feature of the first religions, written language, and philosophy. But our relationship to the Moon became more concrete when Apollo landed on it in 1969 in a moment of scientific and political triumph. And both engineering and politics promise to shape our relationship with it in the near future. Scientists advocate for a return to the moon to do research; governments and billionaires want to return to turn a profit from its mineral resources. Who gets to decide how we use a celestial body that, Boyle argues, belongs to everyone and no one? How can we learn to protect this beautiful, spectral thing that we all share?"--

This book presents the astonishing potential of deep sensorimotor policies for agile vision-based quadrotor flight. Quadrotors are among the most agile and dynamic machines ever created. However, developing fully autonomous quadrotors that can approach or even outperform the agility of birds or human drone pilots with only onboard sensing and computing is challenging and still unsolved.Deep sensorimotor policies, generally trained in simulation, enable autonomous quadrotors to fly faster and more agile than what was possible before. While humans and birds still have the advantage over drones, the author shows the current research gaps and discusses possible future solutions.

The Desert Turned to Glass is a place where the cosmic and chthonic collide. Commemorating the centenary of the planetarium as an architectural type, this book collects a new body of work by acclaimed Canadian artist Charles Stankievech. Thematically, the project explores alternative theories concerning the origin of life, consciousness, and art-bridging the cosmological visions of cave art and the modern technology of the planetarium. Richly illustrated, the book pairs images of Stankievech's installations and cinematic works with newly commissioned writings by geologists, exobiologists, philosophers and archeologists. Spanning the abyss of space and the depths of the earth, The Desert Turned to Glass is an epic meditation on origins, endings, and infinity.CHARLES STANKIEVECH (*1978, Canada) is an artist redefining "fieldwork" at the convergence of geopolitics, deep ecologies, and sonic resonances. From the Arctic's northernmost settlement to the depths of the Pacific Ocean, Stankievech's practice uncovers the paradoxes of our existence on the planet by engaging with the imperceptible. He is Associate Professor at the University of Toronto.

Object Lessons is a series of short, beautifully designed books about the hidden lives of ordinary things.In 1971, the first lunar rover arrived on the moon. The design became an icon of American ingenuity and the adventurous spirit many equated with the space race. The lunar roving vehicles (LRVs) would be the first and last manned rovers to date, but they provided a vision of humanity's space-faring future: astronauts roaming the moon like space cowboys. Fifty years later, that vision feels like a nostalgic fantasy, but the LRV's legacy would pave the way for Mars rovers like Sojourner, Curiosity and Perseverance, who afforded humanity an intimate portrait of our most tantalizingly (potentially) colonizable neighbor. Other rovers have made accessible the world's deepest caves and most remote tundra, extending our exploratory range without risking lives. Still others have been utilized for search and rescue missions or in clean up operations after disasters such as Chernobyl. For all these achievements, rovers embody not just our potential, but our limits. Examining rovers as they wander our terrestrial and celestial boundaries, we might better comprehend our place, and fate, in this universe. Object Lessons is published in partnership with an essay series in The Atlantic.

This book presents an analytical framework for calculating the fracture toughness of generally layered beam structures with an elastically coupled response and hygrothermal stresses. The beam under study features several peculiarities: it consists of multiple layers of dissimilar materials, features bending-extension coupling, and contains residual hygrothermal stresses. Here, a generic analytical model is proposed to compute the energy release rate and the mode mixity. Mechanics of composite materials, crack closure integral, and energetic methods are among the theoretical tools employed for developing the model.A wealth of new closed-form expressions is presented, together with their validation through finite element analyses, which enables investigating various material systems and testing configurations. Experimentalists will find directions for the design and interpretation of delamination tests on laminated composites with uncommon stacking sequences. At the same time, theoreticians can exploit the analytical solution as a benchmark test for more refined analytical and numerical models. Furthermore, the book gives novel insights into the fracture behavior of a titanium-to-CFRP adhesive joint, which is intended for application in the hybrid laminar flow control of a future aircraft. It reports on experiments and theoretical analyses that help understand the behavior of this novel joint. All in all, this book offers extensive updates on methods for fracture analysis of materials with an elastically coupled behavior and residual stresses. It addresses students, researchers, and engineers alike.
