Este libro de carácter divulgador y explicativo, se estructura en dos partes bien diferenciadas. La primera parte de este libro presenta la vida y obra de Albert Einstein, sus creencias, sus temores, su familia, sus amigos, sus enemigos, etc. Una vida repleta de acontecimientos buenos y malos. En la segunda parte se centra en su teoría de la relatividad para hacerla comprensible a cualquier lector. No es fácil explicar la teoría de la relatividad de Albert Einstein. Quizás el símil más apropiado es el siguiente: Cuando dos enamorados están juntos, una hora les parece un minuto. Si nos sentamos sobre una estufa, un minuto nos parece una eternidad. Quién no conoce la famosa fórmula E = m x C². Donde E es energía, m es la masa y C es la velocidad de la luz en el vacío. Casi todo el mundo conoce esta fórmula aunque no sepa lo que significa. Básicamente nos viene a decir que masa y energía son dos formas diferentes de una misma cosa. Es un libro sencillo, fácil de leer, ameno y que seguro ayudará a comprender una de las teorías más conocidas pero a su vez ajenas a la mayoría de las personas sin conocimientos en esta parcela.

PROMOAristóteles, desde joven, quería saber. Quería aprender acerca de todos los aspectos del conocimiento, desde la actividad humana, la política y la ética, hasta todo que veía en la naturaleza. Aristóteles quería comprender el alma de los seres vivos y hallar los métodos de estudios de las diferentes disciplinas. Escribió varias obras en las que reflexionaba sobre todos los aspectos de la naturaleza: el cielo, los planetas y las estrellas, el tiempo, la materia, el movimiento, los animales, las plantas y el cuerpo humano. Sus estudios establecieron las bases del conocimiento sobre el mundo físico, y se convirtieron en la referencia científica durante casi dos mil años. Aristóteles, el deseo de saber" es el sexto volumen de la Colección Científicos, que ya ha narrado con anterioridad las vidas de Darwin, Galileo, Newton, Marie Curie y Ramón y Cajal. -

Launching a major new research project examining the principles of succession law in comparative perspective, this book discusses the formalities which the law imposes in order for a person to make a testamentary disposal of property. Among the questions considered are the following. How are wills made? What precisely are the rules - as to the signature of the testator, the use of witnesses, the need for a notary public or lawyer, and so on? Is there is a choice of will-type and, if so, which type is used most often and what are the advantages and disadvantages of each? How common is will-making or do most people die intestate? What happens if formalities are not observed? How can requirements of form be explained and justified? How did the law develop historically, what is the state of the law today, and what are the prospects for the future? The focus is on Europe, and on countries which have been influenced by the European experience. Thus in addition to giving a detailed treatment of the law in Austria, Belgium, England and Wales, France, Germany, Hungary, Italy, the Netherlands, Poland, and Spain, the book explores legal developments in Australia, New Zealand, the United States of America, and in some of the countries of Latin America with a particular emphasis on Brazil. It also includes chapters on two of the mixed jurisdictions - Scotland and South Africa - and on Islamic Law. The book opens with chapters on Roman law and on the early modern law in Europe, thus setting the historical scene as well as anticipating and complementing the accounts of national history which appear in subsequent chapters; and it concludes with an assessment of the overall development of the law in the countries surveyed, and with some wider reflections on the nature and purpose of testamentary formalities. -
