An astronomer explores the science of astrobiology in this “serious but accessible examination of the prospects for finding life elsewhere in the universe” (Sean Carroll, author of The Big Picture). Describing the most recent discoveries made with space exploration technology, including the Kepler space telescope, the Mars Curiosity rover, and the New Horizons probe, astronomer Jon Willis asks readers to consider five possible scenarios for finding extraterrestrial life. He reviews what we know and don’t know about the life-sustaining potential of Mars’s subsoil ice and the water-ice moons Europa and Enceladus. He also looks at Saturn’s moon Titan through the lens of our own planet’s ancient past. In this concise yet far-reaching volume, Willis even looks beyond our solar system, investigating the top candidates for a “second Earth” in a myriad of exoplanets. “Through humorous, concise, accessible writing, Willis eloquently presents the growing—though still circumstantial—evidence that we are not alone."—Publishers Weekly (starred review)Show book
After the very positive reception to the article entitled “Cual es el papel del psicólogo ante el nuevo Coronavirus (COVID-19)?” (“What is the role of psychology in the face of the new Coronavirus (COVID-19)?”) published in La Cátedra Abierta de Psicológia y Neurociencias on 12th February 2020, and the general interest evoked amongst fellow psychologists and other people with an interest in psychology, I have decided to produce this book, which addresses the subject of the psychological perspective in times of a pandemic. Despite the fact that information concerning health crises such as COVID-19 is very recent and in some cases quite changeable, I am going to present a work based on current data sourced principally from scientific publications, and which will include, from the same sources, statements from various experts. A book accessible to all those who wish to delve into the psychological aspects of a mass phenomenon in times of a health crisis, as in the case of COVID-19.Show book
Falling truly, madly, deeply in love with one animal after another was a recurrent theme of the author's childhood, actively encouraged by her beautiful, impetuous mother as she single-handedly held the family together during the war's darkest days. While her husband's regiment battled through the Tunisian desert to Italy and Austria, she criss-crossed beleaguered Britain with children, ration books, and an unwieldy train of rabbits, dogs, cats and ponies, dreaming of land of her own. But farming can't be learned overnight, and translated into the reality of 400 acres of hilly, rain-lashed Radnorshire, that dream became a challenge for all ranks. Dragooned into acting as unskilled, unpaid labour for jobs that would make today's Health-and-Safety freaks blench – burning rushes, driving tractors, riding on Land-Rover bonnets and towering haywains – the children came to look on boarding-school as a rest-cure, though they retain from those days of carefree, unregulated farm life a treasure-house of memories. This elegant memoir, told with disarming honesty and gentle humour, follows the development of a lively, headstrong, self-effacing young girl into womanhood.Show book
