		<description>with these tablets do you have to use wifi to aitsnll apps and actually do things. or is it kind of just like an ipod touch where you need internet access to do everything. because i have been wanting to purchase one of these tablets but i dont have a lot of hotspots that i can go to everyday i really want a tab where i can actually do things with or without internet access and i was just wondering if this is just like that. and do things come preloaded already or do you need internet ?music?</description>

		<description>Muy bueno! Soy reacio a creer en la eetiixncsa de vida fuera de la Tierra, pero estas noticias hacen que este  un poquito me1s cerca de creer que es posible!O sea en realidad, es tan grande y basto el universo que vida (quize1s no como la conocemos aqued) tiene que haber (y me contradigo, pero me entiendo).</description>

		<description>I understand your cenrocn.  Lawrence Krauss is a smart guy, but it is a shame that he didn&#039;t think the situation through carefully before making such a strong statement.  That&#039;s really not good.OPERA won&#039;t be swept under the rug, but you are right that time and money are a constraint on being able to check it, and that the fact that everyone knows that many experiments (even by good experimenters) come out wrong, and that this one is particularly implausible, is an issue.  But I do think it will happen.  What you have to understand, though, is that anything you propose will take years to build, so you are talking about people taking years of their lives to do it, not to mention justifying the expense, attracting collaborators, and convincing students to work on it.For this reason I suspect that the best approach is to design either a cheap relatively quick test that takes two years or less to build (which very well might be impossible) or, if it is going to take several years anyway, make the measurement part of a larger experimental program, something to be done at a new still-to-be-built or soon-to-be-upgraded facility.  That may sound like an unpleasant compromise, delaying the knowledge by more than necessary, but most particle physics experiments today have to make that compromise.  Also, to justify the cost, the measurement should be more precise than OPERA&#039;s by at least a factor of 10, or be able to reach higher energy neutrinos, or something else novel.So we may very well have to live with OPERA as an anomaly for some years.  You may find that frustrating, but it is very typical; we have been living with DAMA&#039;s claim of dark matter discovery for over ten years, and no one has found their mistake (not that they&#039;ve been very open with their results!) or been able to conclusively confirm it or rule it out (though I&#039;d say we&#039;re closing in on that point.) There are other anomalies out there too.  History books sometimes make science sound like a quick process; it&#039;s not.</description>
