The promise of this little book is an attempt to provide easy extension ("beach") of the main discoveries of the great Albert "EMC2" Einstein! If the author's efforts to achieve this are real small with fairly simple designs, a cutting into very short chapters and via several variants of explanations of the most sensitive points, il'me unfortunately seems that the betting is not required. At the beach my eye or so to begin intensive training and instead very technical! Although passionate astronomy and avid reader of Science and Life and many books on the subjects of cosmology, I challenge the average reader who has never been confronted with these theories navigate the principle lines universe in space-time or do it would be to accept that one is nothing without the other, space and time form an inseparable finally. And it's only the first 30 pages ... Anything else and topics by this test extension ambitions for the layman therefore faces the pitfall of conceptual complexity of these theories and scientific level required to accept them. Honestly, some passages may even revive the worst memories of math class to some. Not by the profusion of incomprehensible formulas, but simply by the unpleasant feeling of being faced with someone who speaks a language you do not understand a word traitor ... For lovers of these topics, the book is against interesting in the sense that he can give them more in-depth understanding of tracks or logic in the speech that the passion would not have found by his own means and knowledge. The fact is that when we speak of special relativity, general, of the universe and other scientific subjects of this importance, we are after all in the realm of belief and acceptance of ideas that only a high level of knowledge for understanding. In short, it is to have faith and to accept the postulates presented, period. Almost identically the great philosophical and religious texts, the ability to accept a better idea than trying to understand seems a better solution. And after all, is it not the poet who said that "the straight line does not exist in the universe, one is because the curved line curved line is that of love" (quoted based on a memory reading and thus necessarily imprecise) one who approached the best human extension of Einstein's theories? This "Einstein on the beach" therefore unlikely to be popular book simply hoped, but simply a test on which pieces needed to achieve those already rubbed (and bitten) to these subjects.
