adorará Adira ao LibraryThing para descobrir se gostará deste livro. Clap-Trap drivel from the latest hyperactive nerd to try his hand at covertly unifying spirituality with modern physics. Kaku put down the "Circle of Iron" DVD. ( )http://pixxiefishbooks.blogspot.com/2... A great book. Definitely a must-read. It's been a while since I last picked up a science book of any kind, but I've become interested more and more in learning about this sort of thing. Over Christmas, a great programme aired on Nova on PBS, called The Elegant Universe, which surveyed the development of multiple dimensions and string theory in the realm of (largely) theoretical physics (also a book, which I intend to read sometime soon as well). I missed it over Christmas (visiting family, etc.), but the programme is available online, and I highly recommend it. Anyway, it's definitely nerdy of me, but it's a field I find interesting (and one in which I have absolutely no training). I haven't taken a physics class since grade 10 (Secondaire IV for all you hard-core Québecers in the crowd). So I resolved to read it in order to better understand the Nova programme. In clear, simple language, Michio Kaku, a professor of theoretical physics at the City College of the City University of New York, outlines the history of the development of the theory of hyperspace. In a nutshell, things are simpler to understand when expressed in higher dimensions. He gives the (commonly-used) example of someone who is flat and lives in a flat, two-dimensional world. To such a Flatlander, a three-dimensional object would not make sense, as it would never remain constant from second to second. For example, if a 3-D apple were to fall onto the Flatlander's world, a Flatlander could only view it in segmented 2-D slices. Brown lines representing the apple stem. Then red or green lines, changing rapidly, first growing larger then smaller, as the apple passes 'through' his world. A Flatlander cannot think in 3-D since there is no way to represent this in his world. We have the same problem living in our three-dimensional world, but it is generally accepted that there are at least four dimensions (the three familiar ones of space, and the fourth of time as posited by Einstein), with the possibility of a fifth (a space-time dimension). However, for hyperspace to be feasible, there are, in fact, many more dimensions - likely 10 or 11. (Some superstring theories, which is related to hyperspace, suggest as many as 26!) Anyway, a good read for anyone who's wondered about physics but was too scared to ask, as it were. Simple language, good explanations, very interesting. Its story was interesting. Like Stephen Hawkings a "Brief History of Time", parts of this are incomprehensible to the layman . I read this book a while back and just realized I never reviewed it. So actually this should probably go against the 2008 numbers, but who cares. This book deals with high dimensional space time theories like superstring theory. This book is very readable for the non-physicists amoung us (myself included). The writing style of Kaku actually made 10 dimensional understandable despite the complex math underlying it and I actually understood how the 10 dimensions actually simplify the laws of nature. Sure I took a couple physics courses in college, but we never got this deep and I'm no where near ready to take on Einstein, but this was actually an enjoyable read for those of you that are interested in seeing what some of the latest theories of space-time are. I've got a few more of Kaku's books on my TBR pile and look forward to tackling them. Hyperspace/Parallel Universe sem resenhas | adicionar uma resenha
