I work in the same building as Herr Weinberg, and I agree with him on all accounts regarding the religious, but damn could he ever be a little less aggressive about it.
We had a public lecture that he held last year on dark energy. Near the end some twit from the audience asked about the (now I'm forgetting his words) recent issues with evolution and intelligent design. Professor Weinberg's response was very similar to:
"There isn't a conflict, there are only idiots who think there is."
Are you serious? Students start attacking an officer and those officers are DAMN well within their rights to start tazing left and right. It's all about managing threat to the officers and protecting their own wellbeing.
I don't think it would look bad to a judge at all. These officers were in the middle of an altercation. The proper thing would be for them to give their badge numbers once the culprit is handcuffed in a squad car. Once people are screaming at officers they are conceivably a threat. As much as I dislike legitimate police brutality, I think police officers damn well need to have the right to act firstmost in order to protect themselves, especially when some stupid punk kid is refusing to listen to them.
These laser pulses are on order 100 femtoseconds. That's 100 * 10^-15 seconds. That works out to only about 3 Watts assuming the 30 TW and 1 shot per second (which is reasonable).
This is nothing compared to the petawatt laser that is being built in the same building here at UT in the same building that this published research was done (one door down from my office in fact). They can only take a shot every 45 minutes after charging a huge bank of capacitors.
Same here actually. The last console I purchased was a Genesis. I'm looking forward to some clever use of the wii-mote. Anyone who's played a game like Osu! Tatakai! Ouendan! for Nintendo DS understands the possibilities!;)
Actually . . . yes! There's a tutorial in the Ubuntu forums on how to get XGL up and running. It isn't enabled by default (obviously) since it's still rather unstable.
I honestly thought I was the only person that ran Win95 beta well into the release cycle. I also thought it was considerably more stable than the final candidate.
Thank you for saying so! This seems to constantly escape many a slashdotter =)

Private School? Chances are if parents found out that Linux was being taught they would ask why resources are spent on that instead of something with real world use. In this case, it's the money of the parents doing the talking. At this point in time what percentage of people (going across all careers) will use linux in the workplace, what, 1%?
Let me just say, that I think firstmost that this is unimportant. I'm a graduate student in physics, so I know a bit about this. But most people in my field will agree that knowing the physics is a lot more important than knowing how to program. In fact, computers are often more of a hindrance to that education. Students that learn to rely too much on solving problems on the computer end up missing out on some of the skills they really need to solve problems and actually *UNDERSTAND* what is going on. Instead they just trust the computer to give them the wrong answer, without any sense of whether that answer is reasonable. I do think that programming is a useful skill, and that undergraduates should get some exposure to it. However, they don't need more than relatively basic programming abilities to do any possible data analysis they need.
The crowd here may not like this, but the *really* good programmers that go into physics tend to focus on it too much. They are looked down on, because they end up becoming 'mechanics' rather than thinkers. If we're talking about academia, this basically dooms you to a life of being a research scientist at best.
Remember the most important point. Computers are just a tool to be used to get to a result, and the results needed by most any scientist require rudamentary programming skills at best.
-- Just on a personal note, I never programmed at all until my 2nd year of undergrad when I needed to learn Fortran to modify some existing simulations. Now I've had a lot of exposure to Java, C, Python, and several other languages. Ya know what? I personally think I'm getting a little past the boundary of healthy balance.
This is true, but I think the question was aimed towards how they supposedly can divide a pixel since it's supposedly the smallest thing they can resolve. I actually worked on a cosmology project for a couple years, so I have at least a rudementary understanding of image capturing techniques. You can overcome the limitations of your CCD through a technique called dithering. The standard dither is 2x2, in which you take an image, move your image to the right by half a pixel, down by half a pixel, left by half a pixel, taking an image at each of these points. Now you can sort of average out these images and can actually resolve things that are smaller than a pixel.
There's a paper somewhere that claims that a 2x2 dither can also eliminate the effects from any 'reasonable' intrapixel variation. That is, if for example the edges of your pixels are slightly less sensitive than the centers, which is actually quite common. This makes dithering an extremely valuable technique in wide surveys where the characteristic size of an object in the sky is less than the size of a pixel. This is called undersampling. I could say more, but I think that answers the question.;)
Thank you, thank you, thank you... Thank you Vatican for being composed of intelligent people. I don't particularly agree with any type of creationist science, but I have little qualm, and in fact would have a lot more respect for an "intelligent designer" to have set up a self-sustaining and evolving system. Otherwise the intelligent designer isn't so intelligent.
Ha! He mentions that he has 65 peer-reviewed citing and discussing his theory. Search scholar.google.com for RL Mills. The second entry is his book. Click on the Cited link, and you'll notice that there are indeed many papers citing his work. And sir Mills himself is first author on just about all of them.
Just a correction.... Being a Physicist, I swear I remember in undergraduate classes learning that the reason there is no Hydrogen in the atmosphere, is because at what are considered normal temperatures Hydrogen has enough kinetic energy such that it has escape velocity. It just flies into space.;)

(No, it's not pr0n). My colleagues and I glance over the abstracts posted in our field every day. It's a great resource for to know what's going on in your field. We use it primarily as fodder for intellectual discussions, but eh. Check it out.
that people mistake $400 manufacturing cost for $400 sticker price. Read the article carefully. If that's what it costs them to make it, you can be sure it'll be at least twice that in the store.
I read this book almost 2 years ago now. I had actually forgotten about it. But now that I remember, I can recall a bit of how it really made me smile at points.
It's an excellent read, although it seemed a little light to me. Not exactly like reading a Tolstoy novel. It was much more simplistic in its language. But overall, I don't regret for a second the $20 I plunked down for the hardcover.
Hmm, my original understanding was that as part of the deal with Dec Compaq was required to release much of the Alpha technology as public domain. Intel never seemed to take advantage of this, but where do you think AMD took a lot of their architecture design from? I could be wrong, but I recall this being the case.
They say on the site that these are fairly unreliable and that data corruption is somewhat commonplace. Don't know how bad, like tape backup, or worse?

I have not read the BBC article. But this is the official PR document. It's nice having relatives in the field. I had this news days ago.
Not racist, huh? I'd be hard pressed to tell the difference between any middle eastern accents, yet you seem to be an expert.
