En pocos territorios como en la Luna se producen tantas batallas encarnizadas entre realidad y fantasía. Lunáticos, brujas y hombres lobo conviven en nuestro imaginario con las rocas lunares, los calendarios, las mareas y las proezas tecnológicas que lograron llevar a una docena de privilegiados a ver sus huellas eternizarse sobre el polvo de su superficie. Nuestro satélite nos fascina porque, en realidad, nos refleja a nosotros mismos.

Hace 13.000 años la evolución de las distintas sociedades humanas comenzó a tomar rumbos diferentes. La temprana domesticación de animales y el cultivo de plantas silvestres en el Creciente Fértil, China, Mesoamérica y otras zonas geográficas otorgó una ventaja inicial a sus habitantes. Sin embargo, los orígenes localizados de la agricultura y la ganadería son solo una parte de la explicación de los diferentes destinos. Las sociedades que superaron esta fase de cazadores-recolectores se encontraron con más probabilidades de desarrollo, supervivencia y poder bélico.

Why is the genome of a salamander 40 times larger than that of a human? Why does the avocado tree produce a million flowers and only a hundred fruits? Why, in short, is there so much waste in nature? In this lively and wide-ranging meditation on the curious accidents and unexpected detours on the path of life, Daniel Milo argues that we ask these questions because we’ve embraced a faulty conception of how evolution - and human society - really works.

We live at the bottom of an ocean of air - 5,200 million million tons, to be exact. It sounds like a lot, but Earth’s atmosphere is smeared onto its surface in an alarmingly thin layer - 99 percent contained within 18 miles. Yet, within this fragile margin lies a magnificent realm - at once gorgeous, terrifying, capricious, and elusive. With his keen eye for identifying and uniting seemingly unrelated events, Chris Dewdney reveals to us the invisible rivers in the sky that affect how our weather works and the structure of clouds and storms and seasons, the rollercoaster of climate.

Le statistiche parlano chiaro: il 40% delle persone che abita in condominio ha un problema di rumore che non ha ancora risolto. La cosa triste è che la maggior parte di queste persone non prova neanche a migliorare la propria situazione attuale perché pensa che non esistano soluzioni efficaci per contenere questo genere di rumori. 

Ti sei mai chiesto quanto può essere invasivo, fastidioso e penetrante un rumore protratto nel tempo? La sensazione che si prova è un misto di rabbia, amarezza e malessere. Pensa che qualche volta sembra di sentirlo anche quando non c'è e la cosa peggiore è che non si riesce ad averne il controllo. Magari non ci hai mai pensato prima, ma questa esposizione continua a danneggiare l'equilibrio degli individui e li porta dritti all'ansia. La soluzione? È senza dubbio l'insonorizzazione, a patto però di trovare qualcuno di esperienza a cui affidarsi totalmente.

For almost 40 years, Chet Raymo walked a one-mile path from his house to the college where he taught, chronicling the universe by observing every detail of his route with a scientists curiosity, a historians respect for the past, and a childs capacity for wonder. With each step, the landscape he traversed became richer, suggesting ever deeper aspects of astronomy, history, biology, and literature, and making the path universal in scope.

An energizing case for hope about the climate comes from Rebecca Solnit, called “the voice of the resistance” by the New York Times, and climate activist Thelma Young Lutunatabua, along with a chorus of voices calling on us to rise to the moment. Not Too Late is the book for anyone who is despondent, defeatist, or unsure about climate change and seeking answers. As the contributors to this volume make clear, the future will be decided by whether we act in the present—and we must act to counter institutional inertia, fossil fuel interests, and political obduracy.

When Monisha Rajesh announced plans to circumnavigate the globe in 80 train journeys, she was met with wide-eyed disbelief. But it wasn’t long before she was carefully plotting a route that would cover 45,000 miles - almost twice the circumference of the earth - coasting along the world’s most remarkable railways; from the cloud-skimming heights of Tibet’s Qinghai railway to silk-sheeted splendour on the Venice Simplon-Orient-Express. Packing up her rucksack - and her fiancé, Jem, Monisha embarks on an unforgettable adventure.
