Stephen Hawking fue reconocido como una de las mentes más brillantes de nuestro tiempo y una figura de inspiración después de desafiar su diagnóstico de ELA a la edad de veintiún años. Es conocido tanto por sus avances en fisica teorica como por su capacidad para hacer accesibles para todos conceptos complejos y destaco por su travieso sentido del humor. En el momento de su muerte, Hawking estaba trabajando en un proyecto final: un libro que compilaba sus respuestas a las grandes preguntas que a menudo se le planteaban: preguntas que iban mas alla del campo academico. Dentro de estas paginas, ofrece su punto de vista personal sobre nuestros mayores desafios como raza humana, y hacia donde, como planeta, nos dirigimos despues. Cada seccion sera presentada por un pensador lider que ofrecera su propia vision de la contribucion del profesor Hawking a nuestro entendimiento.

En Las diez claves de la realidad el premio Nobel Frank Wilczek desgrana con un lenguaje sencillo, libre de tecnicismos pero con absoluto rigor, lo que considera las diez claves para la comprensión cientifica de la realidad fisica. Con claridad y un contagioso tono alegre, nos guia a traves de los conceptos esenciales que forman nuestra comprension de lo que es el mundo y como funciona. A traves de estas paginas, llegamos a ver nuestra realidad de una manera nueva: mas grande, mas completa y mas extraña de lo que parecia antes.Sintetizando preguntas basicas, hechos y especulaciones deslumbrantes, Wilczek investiga las ideas que forman nuestra comprension del universo: tiempo, espacio, materia, energia, complejidad y complementariedad. Ahonda en la historia de la ciencia fundamental, explorando lo que sabemos y como lo sabemos, al tiempo que viaja a los horizontes del mundo cientifico para darnos una idea de lo que podriamos descubrir pronto. Brillante, lucido y accesible, este es un libro esencial que nos enseña a ver la realidad con nuevos ojos y que celebra los grandes logros del metodo cientifico.

Steven Weinberg, premio Nobel de Física por su contribución a la unificación de dos de las fuerzas básicas de la naturaleza -la fuerza débil y el electromagnetismo-, aborda en este libro la gran aventura intelectual de nuestro tiempo: la busqueda de una teoria final, aquella en la que todas las preguntas fundamentales hallarian respuesta sin requerir una explicacion en terminos de otros principios. Weinberg, que no solo es un gran fisico sino un excelente divulgador, nos explica de manera llana y comprensible la idea de esta teoria final, los pasos que han conducido hacia ella ylos obstaculos que encuentra, dejandonos en la frontera de esa tierra prometida.

Acaso tenían razón los griegos cuando afirmaban que al principio solo reinaba el caos. Así parecen confirmarlo muchas observaciones de la física moderna. Pero ¿qué ocurrió en los primeros instantes de vida del universo? Y hoy en dia ¿es el universo ese sistema organizado y fiable que creemos ver o sigue estando dominado por el desorden primordial?Para responder a estas cuestiones, una multitud de cientificos exploran cada dia los rincones mas reconditos de la materia. ¿Podemos decir entonces que los grandes telescopios o los aceleradores de particulas, al igual que los relatos mitologicos en la Antiguedad, tratan de comprender la singularidad que dio origen al universo y reconstruir los mecanismos que caracterizan a muchas de las maravillas que nos rodean y que nos resultan familiares? Asi nos lo demuestra Guido Tonelli en este extraordinario libro. Valiendose de la mitologia griega, el autor nos ofrece el gran relato de los origenes que se deriva de la ciencia moderna y nos permite comprender la importancia de las cosmogonias para hallar nuestro lugar en el universo.

Quién no ha visto el cielo estrellado y se ha preguntado: “Qué significa todo esto”, “Cómo funciona el universo”, “Cuál es mi lugar en el cosmos”Si estás tan ocupado como para tomar clases o leer lib

R.A. D'Inverno There is little doubt that Einstein's theory of relativity captures the imagination. Not only has it radically altered the way we view the universe, but the theory also has a considerable number of surprises in store. This is especially so in the three main topics of current interest that this book reaches, namely: black holes, gravitational waves, and cosmology. The main aim of this textbook is to provide students with a sound mathematical introduction coupled to an understanding of the physical insights needed to explore the subject. Indeed, the book follows Einstein in that it introduces the theory very much from a physical point of view. After introducing the special theory of relativity, the basic field equations of gravitation are derived and discussed carefully as a prelude to first solving them in simple cases and then exploring the three main areas of application. Einstein's theory of relativity is undoubtedly one of the greatest achievements of the human mind. Yet, in this book, the author makes it possible for students with a wide range of abilities to deal confidently with the subject. Based on the author's fifteen years experience of teaching this subject, this is achieved by breaking down the main arguments into simple logical steps. The book includes numerous illustrative diagrams and exercises (of varying degrees of difficulty), and as a result this book makes an excellent course for any student coming to the subject for the first time.

Provides a semi-quantitative approach to recent developments in the study of optical properties of condensed matter systemsFeaturing contributions by noted experts in the field of electronic and optoelectronic materials and photonics, this book looks at the optical properties of materials as well as their physical processes and various classes. Taking a semi-quantitative approach to the subject, it presents a summary of the basic concepts, reviews recent developments in the study of optical properties of materials and offers many examples and applications.

Solar radiation data is important for a wide range of applications, e.g. in engineering, agriculture, health sector, and in many fields of the natural sciences. A few examples showing the diversity of applications may include: architecture and building design e.g. air conditioning and cooling systems; solar heating system design and use; solar power generation; weather and climate prediction models; evaporation and irrigation; calculation of water requirements for crops; monitoring plant growth and disease control; and, skin cancer research. Solar radiation data must be provided in a variety of forms to suit these applications. The radiation reaching the upper atmosphere of the Earth is a quantity rather constant in time. But the radiation reaching some point on Earth surface is random in nature. The main cause is the fact that various gases within the atmosphere absorb solar radiation at different wavelengths, and clouds and dust also affect it. There are two ways to obtaining solar radiation data at ground level: by measurement and by modelling.The book will facilitate the calculation of solar radiation required by engineers, designers and scientists and, as a result, will increase the access to needed solar radiation data.

The Sixth Edition of Physics for Scientists and Engineers offers a completely integrated text and media solution that will help students learn most effectively and will enable professors to customize their classrooms so that they teach most efficiently.

Written by one of the founding fathers of Quantum Information, this book gives an accessible (albeit mathematically rigorous), self-contained introduction to quantum information theory. The central role is played by the concept of quantum channel and its entropic and information characteristics. In this revised edition, the main results have been updated to reflect the most recent developments in this very active field of research.
