See the world. Then make it better.''I am 94. I''ve had an extraordinary life. It''s only now that I appreciate how extraordinary. As a young man, I felt I was out there in the wild, experiencing the untouched natural world - but it was an illusion. The tragedy of our time has been happening all around us, barely noticeable from day to day - the loss of our planet''s wild places, its biodiversity. I have been witness to this decline. A Life on Our Planet is my witness statement, and my vision for the future. It is the story of how we came to make this, our greatest mistake - and how, if we act now, we can yet put it right.We have one final chance to create the perfect home for ourselves and restore the wonderful world we inherited.''All we need is the will to do so.''

In 2008 an extraordinary two-minute film clip appeared on YouTube and immediately became an international phenomenon. It captures the moving reunion of two young men and their pet lion Christian, after they had left him in Africa with "Born Free's "George Adamson to introduce him into his rightful home in the wild. "A Lion Called Christian "tells the remarkable story of how Anthony "Ace" Bourke and John Rendall, visitors to London from Australia in 1969, bought the boisterous lion cub in the pet department of Harrods. For several months, the three of them shared a flat above a furniture shop on London's King's Road, where the charismatic and intelligent Christian quickly became a local celebrity, cruising the streets in the back of a Bentley, popping in for lunch at a local restaurant, even posing for a fashion advertisement. But the lion cub was growing up--"fast"--and soon even the walled church garden where he went for exercise wasn't large enough for him. How could Ace and John avoid having to send Christian to a zoo for the rest of his life? A coincidental meeting with English actors Virginia McKenna and Bill Travers, stars of the hit film "Born Free," led to Christian being flown to Kenya and placed under the expert care of "the father of lions" George Adamson. Incredibly, when Ace and John returned to Kenya to see Christian a year later, they received a loving welcome from their lion, who was by then fully integrated into Africa and a life with other lions. Originally published in 1971, and now fully revised and updated with more than 50 photographs of Christian from cuddly cub in London to magnificent lion in Africa, " A Lion Called Christian "is a touching and uplifting true story of an indelible human-animal bond. It is is destined to become one of the great classics of animal literature.

This text attempts to change the way logic and discrete math are taught in computer science and mathematics. While many books treat logic simply as another topic of study, this book''s uniqueness is its willingness to take it one step further. In the book, logic is treated as a basic tool, to be applied in essentially every other area. "This is a rather extraordinary book, and deserves to be read by everyone involved in computer science and - perhaps more importantly - software engineering. I recommend it highly. The book will be of value not only to beginning students, but also to hardened programmers with many years of experience - in Fortran, Cobol, C, C++, or whatever. If the book is taken seriously, the rigor that it unfolds and the clarity of its concepts could have a significant impact on the way in which software is conceived and developed. " -Peter G. Neumann-

Medramos coa presenza limpa das rectas, tan simples, tan útiles, sen dubidar da súa consistencia, malia vivirmos nunha superficie curva, aceptando o seu carácter ilimitado, ao abeiro dun espazo infinito, teimosos na ignorancia. Se cadra asumimos a ficcion como necesaria, presos de ideas primitivas, nacidas de experiencias limitadas que sufriron xeneralizacions abusivas e se converteron en principios inmutabeis, conturbando a nosa razon. Agora sabemos que non, que a recta e unha aparencia, aquela precisa simplicidade da xeometria escolar. E xorden outras xeometrias, outras teorias fisicas... Aprendemos que o universo non se corresponde coa idea de espazo plano e infinito, que a sua xeometria varia dun lugar a outro e muda permanentemente coas diversas configuracions materiais! Estas paxinas percorren unha longa marcha, a longa historia da evolucion das teorias xeometricas, desde os albores da civilizacion ata esa modernidade que fai eclosion no seculo XIX. Unha andaina instrutiva que arriba a unha abstraccion insospeitada, derrubando a ilusion dunha xeometria natural.

As part of the boom in biotechnology, particularly in tissue engineering, primary human cell culture has become a major pillar in academic research and the biopharmaceutical industry. Obtaining a viable culture from a tissue sample and maintaining it for experimental, diagnostic or therapeutic purposes can be quite a challenge. Based on laboratory protocols and practical experience from many years of primary cell culture, this manual presents the basic steps necessary for culturing primary human cells. Written by students for students, the manual serves well as a practical guide to primary human cell culture. The authors have left much space for notes and the design of the manual is such that it can be continuously upgraded and extended. The content of this manual is by no means exhaustive. Protocols for specific cell types, out of over 200 different cell types in the human body, were selected from major tissue groupings in the body. They should serve as a foundation for individual researchers to experiment, explore, and establish niche protocols for their specific needs. Inspired by the practical clinical checklists available to residents and trainees in medicine, the authors have chosen a compact physical format that can fit into the pocket of a lab coat.

Quizá no haya forma más elegante y eficaz de comprimir una reflexión que un aforismo inspirado, capaz de reducir el pensamiento a su forma más compacta y por tanto universal. Como dice Wagensberg en el prologo a este libro, una idea buena que no cabe en veinte palabras, no es una idea tan buena. En la estela de Si la naturaleza es la respuesta, ¿cual era la pregunta? (2003), que desperto el entusiasmo de critica y lectores, esta coleccion de aforismos viene a ser una continuacion natural en la que Wagensberg vuelve a asombrar por su habilidad para aunar la profundidad de las cuestiones con el efecto sorpresa de una formulacion siempre ingeniosa. Ademas, las frases y aforismos se seducen unos a otros, formando pequeños encadenamientos que operan como una original aproximacion a las grandes cuestiones fundamentales la verdad, lo bello y lo inteligible, la matematica, naturales la seleccion y la evolucion y culturales construcciones y fronteras de lo humano, los museos y el arte.
