El exito obtenido por la Historia del tiempo, de Stephen Hawking, propicio la creacion, en 1991, de esta coleccion de divulgacion cientifica que fue dirigida durante largo tiempo por dos personas de formacion humanistica: de ahi ciertas contaminaciones al inicio de la coleccion. Sin embargo, cuando Jose Manuel Sanchez Ron se hizo cargo de ella, dio un aprobado a la gestion anterior. En esta coleccion, quiza la mas ambiciosa de todas las de divulgacion cientifica que se editan en espanol, se han publicado obras de Stephen Jay Gould, Carl Sagan, lan Stewart, Edward O. Wilson, Antonio Damasio, Luigi Luca Cavalli-Sforza, Ilya Prigogine, John D. Barrow, Rita Levi Montalcini, Richard P. Feynman, Roger Penrose, Steven Weinberg, Rachel Carson, Francisco Garcia Olmedo, Francisco Yndurain o Jose Manuel Sanchez Ron. En el ano milagroso de 1905, Albert Einstein, entonces todavia un desconocido empleado de la Oficina de Patentes de Berna, publico cinco articulos, hoy imprescindibles para conocer el desarrollo de la fisica, y, en mas de un sentido, de la humanidad. Estos son los trabajos que se incluyen en este libro, acompanados por magistrales explicaciones de cientificos tan celebrados como John Stachel y Roger Penrose.
For someone who has read extensively in mathematics and physics the Miraculous Year was nonetheless a difficult read. John Stachel's historical and editorial reviews of the five papers are very helpful, and it is clear from his reviews that to understand fully the train of Einstein's thought and the intelligence of his physical insights one must go back prior to 1900 to read previously published papers by Einstein and others that he referenced because Einstein, despite his usual emphasis on clarity of presentation, assumes the reader has knowledge of hydrodynamics, thermodynamics, statistical mechanics, and electricity and magnetism, particularly Maxwell's equations. It is therefore humorous if not ironic that Einstein apologizes for his lack of mathematical ingenuity and rigor (believe me, there is plenty of mathematics in these five papers) because he saw that "mathematics was split up into numerous specialties, each of which could easily absorb the short lifetime granted to us" which could easily be said of the aforementioned fields in physics which Einstein mastered sufficiently for the Miraculous Year papers. In biographies of Einstein I have learned that he actually submitted several dissertation thesis papers but subsequently withdrew them before completing the final thesis in 1905. Biographers suggest that the final dissertation evolved from the earlier attempts. I do not have enough years to backtrack to those pre-1900 papers. Nonetheless without going back to pre-1900 papers I like most people with a knowledge of calculus and a moderate amount of concentrated study can understand the Miraculous Year papers enough to appreciate fully Einstein's brilliant mind. The reader may have a harder time following some of Stachel's historical notes which refer sometimes obliquely to other works in order to put Einstein's papers both in historical context and critical scrutiny. Understanding Stachel would require another lifetime.
... radiação do corpo negro, fotoluminiscência, produção de raios catodicos por luz ultravioleta e outros fenômenos associados a emissão ou transformação da luz podem ser mais facilmente entendidas se admitimos que a energia da luz é distribuída de forma descontínua no espaço. De acordo com a hipótese aqui considerada, na propagação de um raio de luz emitido por uma fonte puntiforme, a energia não é continuamente distribuída sobre volumes cada vez maiores de espaço, mas consiste em um número finito de quanta de energia, localizados em pontos do espaço que se movem sem se dividir e que podem ser absorvidos ou gerados somente como unidades integrais.
Everyone that works or studies in science fields knows and acknowledges the fundamental importance of the 1905 Einstein's "Annus Mirabilis Papers" and the impulse they gave to the later developement of 20th century modern physics. They are all shown in this book, in high fidelity to the original paper written by Einstein's himself, and the author brings some explaination and historical context to all of them. They're still quite hard concepts, but if you want to start digging deeper into this field you have to expect some difficulties, and if you're willing to do so this book is one of the best way to introduce you to the topic.
Los 5 artículos producidos por Einstein en 1905 revolucionaron la física y cambiaron el paradigma científico de su tiempo, desde los estudios en brownian motion hasta la relatividad general y la especial, el trabajo en su Annus Mirabilis sigue siendo de las teorías más corroboradas en la historia ( junto con la mecánica cuántica )
La claridad con la que escribe y la elegancia matemática y las técnicas que desarrolla sean relativas a física estadística o atractores de Lorentz es asombrosa.
Es un Libro extraordinario y muy recomendando naturalmente para todo estudiante de física y en general para todo amante de la ciencia, de la filosofía de la ciencia.
Las palabras de Penrose al principio del libro describen con claridad el impacto del "año maravilloso"
