I have chosen to review this book because it was released recently (end of Feb, 2010).]
Have you ever wanted to buttonhole a physicist at a cocktail party? Do you have the burning desire to sit down with a professor and ask a laundry list of "physics" questions about time travel and black holes? Do you want to know more about modern physics, but want to do it with pop culture experiments instead of mathematics? If you answered "yes" to any of those questions, then you're in the target audience for A User's Guide to the Universe: Surviving the Perils of Black Holes, Time Paradoxes, and Quantum Uncertaintym
A User's Guide to the Universe (hereinafter "A User's Guide") is the physicist's answer to Phil Plait's Death from the Skies!: These Are the Ways the World Will End.... What Goldberg and Blomquist have created is a fun, light read about interesting areas of modern physics that will entertain while it educates. The book assumes very little scientific background on the part of the reader. Those with some knowledge (this is Slashdot, after all) will find the explanations of well-known concepts (the double slit experiment, for example) lucid, direct, brief and entertaining.
A User's Guide covers topics like relativity, time travel, the Standard Model of Particle Physics, and alien life. It does so with a very tongue-in-cheek sense of humour, and footnotes that act as the authors' very own peanut gallery. While this humour lightens up what could otherwise be a few dry areas of discussion, the littering of the text with pop-culture references is bound to make the book feel a bit dated in years to come. For now (March 2010), though, A User's Guide is so fresh you might call it ripe.
Unlike Death from the Skies, this book is well illustrated. The pen-and-ink cartoons are omnipresent, and serve to both illustrate the text, and to take every opportunity for a joke (cheap or otherwise) that presents itself. Overall, I felt that the cartoons were a strong addition to the book, as they can provide a needed laugh in a serious section, or can eliminate the proverbial thousand words when describing an experiment or concept.
The chapter on time travel is a stand-out. It presents several "practical" designs for time machines, which use black holes, cosmic strings or wormholes as components. I am an avid reader of pop-sci books, and I found designs that were new to me. The discussion of the Grandfather Paradox (if you go back in time and kill your grandfather, then you were never born and could never have committed murder) and ways around it are very helpful and present a solid physical framework for thinking about these issues. When the Grandfather Paradox is reformulated using pool balls, instead of thinking humans, it becomes clear that the issues are physical and not metaphysical. Also, the authors helpfully include a chart ranking sci-fi shows and movies for their time travel savvy.
You'll also find a strong and entertaining treatment of inflationary cosmology, including discussions of the evidence behind the theory and a look at some consequences. This book avoids both a heavy technical treatment and a historical look at the development of the theory (see, for example, Alan Guth's The Inflationary Universe for that) and instead dives right in to the juiciest parts. This style is well-suited to the reader who wants the funs bits without all of the baggage.
If you're curious about quantum mechanics, the second chapter contains a one of the best introductions in the field. By asking questions like "can we build a Star Trek transporter?" the authors drive a quick and satisfying tour through the weirdness of the microscopic world. This "evil genius hands-on" approach is this book's most important contribution to pop sci literature, and its most endearing feature. You'll start by looking at Star Trek, but end with the mysteries of the double-slit experiment, wave-particle duality and the uncertainty principle.
Finally, at the end of the book, the authors helpfully include two sets of references: one to the pop sci literature, and one to the technical literature. Many of the best pop physics books of the past are listed, and the bibliography could serve as useful direction to more depth for the interested.
Overall, A User's Guide accomplishes what it sets out to do. It combines a hands-on, question-driven approach to physics with a tongue-in-cheek, pop-culture-based sense of humour. And then it throws on a layer of great cartoons to make the entire package something that most science books aren't: enjoyable. This book is fine, and you may well learn something in the process."
I think that academically, I am doing well. I am president of the Computer Club, participate in the math team, have good grades, etc. My dream is to get into MIT. But for any college/university, not just MIT, how much would early graduation hurt my chances? If I get great SAT scores, AP scores and GPA, would that outweigh the 5 (or so) less classes I take than everyone else? Note, also, that I am older than most others in my grade, so the whole age thing should not be a problem.
Does anyone in the Slashdot community have any experience with early graduation?"
"The implications of this resolution will be widespread, generally enhancing the scientific community's comprehension of relativity. It may eventually even have some impact on quantum communications and computers, potentially making it possible to design more efficient and reliable communication systems for space applications."
It's a fascinating story — even names one person at Microsoft."
According to this article MythTV actually has several features that a TiVo will never be able to compete with but is considerably harder for the non-geek to initially setup and then maintain. A huge ding against MythTV is the fact it does not support CableCARD like the Series 3. Since I'm OTA, that's not as big of a deal, but what are your thoughts? MythTV vs Series 3?"
