Relativity: The Special and the General Theory

I was disappointed in the contents of this internationally-famous book written by one of the most famous people ever to have lived. I expected sharp, well-stated, arguments to support his proposed theories of relativity. I found, instead, a sketchy set of arguments written in a pompous, self-righteous style. Not only that, but I found the majority of his arguments to be poorly constructed and, in many cases, unacceptable. His problem is that—being a genius—he frequently expects his readership to accept his opinion without support. In general terms, his book is written in an early 20th Century style. He suffers from having the modern range of practical engineering and scientific technology upon which to base his logic. Frankly, if this book had been published in the early 21st Century, it could not have been accepted by any educated reader. Einstein's theories of relativity have, as mathematical operators, been so successful that science automatically assumes the foundations of his theories must have been sound. Having read his book, I no longer believe that to be the case.

Bon livre. Livré rapidement.

It is Only for those who already have understanding of basic physics ( Newtonian mechanics) and maths. And those who specially want to understand relativity (special relativity) by the discoverer himself. Then this book is for you. Else skip this book.

El libro es muy breve y superficial. No entra en ningún detalle. No da ninguna definición de los conceptos requeridos para entender la teoría, ni de los avanzados ni de los básicods. Ni siquiera identifica los conceptos utilizados para que el lector pueda utilizar otras fuentes para formarse en ellos y aplicarlos para poder entender la teoría. Es un libro para quienes son expertos en la teoria, conocen todos sus detalles y les va bien una breve síntesis. El resto de los lectores, se quedará con una lecture muy breve y agradable que no les aportará mucho.

One of the best books for young students in high school and anyone who wants to understand relativity. It is a pleasure to read the words of Einstein.
