Submission + - Book Review: A User's Guide to the Universe

alfredw writes: "[NOTE TO EDITORS: Disclosure: I am a graduate student in the same department as one author (Goldberg). I've taken his Cosmology and Graduate Electricity and Magnetism class. He's not my academic advisor, nor is he on my thesis committee and he has no determination of my grades or future performance. I also shared an office with the other author (Blomquist) for about a week in 2008, when I was joining the department and he was leaving. We're casual acquaintances only.

Please publish only my obfuscated email address.

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."

Senator Proposes to Monitor All P2P Traffic for Illegal Files 626

Posted by Zonk from the kind-of-strains-the-mind-to-think-about-huh dept.
mytrip writes "Senator Joe Biden (D-Del) has proposed an ambitious plan, costing on the order of $1 billion, aimed at curtailing illegal activities via P2P networks. His plan involves utilizing new software to monitor peer-to-peer traffic on an ongoing basis. 'At an afternoon Senate Judiciary subcommittee hearing about child exploitation on the Internet, Sen. Joe Biden (D-Del.) said he was under the impression it's "pretty easy to pick out the person engaged in either transmitting or downloading violent scenes of rape, molestation" simply by looking at file names. He urged use of those techniques by investigators to help nab the most egregious offenders."

Submission + - Microsoft dirty tricks that were never revealed

Submitted by Conrad Mazian
Conrad Mazian writes: Robert X. Cringely has an article on the Technology Evangelist web site where he claims that Microsoft destroyed evidence in the Burst vs Microsoft case. Specifically Burst's lawyers had asked for certain emails, Microsoft claimed that they couldn't find the backup tapes the emails would be on, and while this was happening the tapes were in a vault at Microsoft — until they mysteriously disappeared.

It's a fascinating story — even names one person at Microsoft.

Microsoft Blasts IBM Over XML Standards 323

Posted by Zonk from the dude-i-am-so-telling-mom dept.
carlmenezes writes "Ars Technica has up an article discussing Microsoft's latest salvo against IBM. Microsoft's open letter to IBM adds fresh ammunition to the battle of words between those who support Microsoft's Open XML and OpenOffice.org's OpenDocument file formats. Microsoft has strong words for IBM, which it accuses of deliberately trying to sabotage Microsoft's attempt to get Open XML certified as a standard by the ECMA. In the letter, general managers Tom Robertson and Jean Paol write: 'When ODF was under consideration, Microsoft made no effort to slow down the process because we recognized customers' interest in the standardization of document formats.' In contrast, the authors charge that IBM 'led a global campaign' urging that governments and other organizations demand that International Standards Organization (ISO) reject Open XML outright."

Google, Submission AdSense and NoFollow Letdown 104

Posted by ScuttleMonkey from the still-watching-through-the-window dept.
John Battelle is reporting on his blog that word has leaked about a possible new API from Google that would allow sites to distribute AdSense earnings to individual members based on submissions or participation. From the article: "To toss a bit of cold water here, however, I've never seen UGC sites as the least bit driven by money. They are driven by pride, the desire to be first, reputation, whuffie. But dollars? That often screws it all up. I guess we'll get to see soon enough..." Relatedly many users are calling the 'nofollow' tag "Google's embarrassing mistake". Justin Mason is just one of many to take a look at the current status of nofollow and what may still be in store for that particular tool.

Somehow I managed to get modded as 5, Troll. I don't know how this managed to happen, but according to one post i'm in an official /. club or something. Sounds cool :-p

You are honoring the people that died to give you your freedom, if you think that because we've messed up in the past you should not salute the flag, then don't say anything, but stand out of respect. Whether we've done bad things in the past or not does not nullify the fact that people sacrificed their lives to give you the freedom to insult them, and their country. If they didn't do what they did, we might live under a government that would shoot you for not standing, or cut out your tongue for not saying the pledge. I don't see anything wrong with teaching 'schoolkiddies' to respect and honor their country.
