Este libro inició la ciencia moderna. Galileo se propuso cambiar la vieja visión física y filosófica, transformar el sentido común y la mentalidad que ahora consideramos pre-moderna. Este libro es a la vez de ciencia fisica y astronomia, y de epistemologia, logica y filosofia de la cultura. Esta escrito en forma de dialogo para poder ofrecer la dialectica entre la vieja y la nueva vision de la naturaleza.

Natural hazards afflict all corners of the Earth; often unexpected, seemingly unavoidable and frequently catastrophic in their impact. This revised edition is a comprehensive, inter-disciplinary treatment of the full range of natural hazards. Accessible, readable and well supported by over 180 maps, diagrams and photographs, it is a standard text for students and an invaluable guide for professionals in the field. Clearly and concisely, the author describes and explains how hazards occur, examines prediction methods, considers recent and historical hazard events and explores the social impact of such disasters. This revised edition makes good use of the wealth of recent research into climate change and its effects.

Following an approach that supports the new 2007 syllabus and including the wider aims of the IBO this book makes connections to TOK, international-mindedness and the IB learner profile. It has been written by a former chief examiner for IB Diploma Programme Physics and has been extensively reviewed by teachers, consultants and the IBO. With features and activities that encourage active learning and critical thinking, students will find this book stimulating and engaging. Readership : Students of the IB Diploma Programme in Physics and anyone who would like a clear and unique resource for Physics

Este libro se inició en forma de un conjunto de notas preparadas para un curso que ofreció el Departamento de Mecánica técnica de la Universidad de Michigan durante varios años. Normalmente, el curso lo elegian estudiantes de primer curso para postgraduados en Mecanica, si bien tambien lo siguieron candidatos al doctorado y al titulo de Master procedentes de otros programas de Ingenieria, asi como algunos alumnos aventajados que aun no se habian graduado.

Richard Feynman was the first to propose the idea of applying the laws of quantum physics to perform computational tasks in 1982. David Deutsch then generalised the notion of a Turing machine to the quantum realm, in-troducing the notion of a universal quantum computer. In this system, the bit (the classical unit of information) is replaced by the quantum bit or qubit. The quantum superposition principle allows the qubit to be in any superposition state a 0⟩ + b 1⟩, instead of being in just one of the two states 0 or 1 as a classical bit. This "quantum parallelism" is the key property of a quantum computer, which provides access to an exponentially larger set of states to process information. It makes it possible to simulate quantum systems that classical computers cannot afford due to their size. It could also solve new tasks, as creating true random numbers, and improve others such as the database searching, and prime number factorisation.

This thesis addresses 2 challenges in biomaterials research: 1) diffusion phenomena in Ti-Al-Nb alloys as materials for structural applications; and 2) the development of magnetic hyperthermia therapies against cancer more efficient and less invasive. Both challenges share a characteristic physical ground, which is the guideline of this work: they are based on transfer phenomena, mass transfer in the first case, and heat transfer in the second.
