Comment Re:Higgs not responsible for most mass (Score 1) 253 253

He's actually right (sort of) ---> review paper

The Higgs serves to explain the mass of the W & Z bosons, plus the quarks that make up nucleons, but for various reasons (explained in the previous link), the mass of the individual constituent quarks does not contribute to the observed mass of the nucleons. Rather, that comes from back-reaction forces provided by QCD. The mass of neutrons & protons, and thus most normal matter, has been predicted by theory long ago.

It's not binding energy like he said, but he's right to say that the Higgs mechanism doesn't explain the masses of protons or neutrons.

Submission + - Google using reCAPTCHA to decode street addresses->

smolloy writes: Apparently some users of reCAPTCHA have recently begun seeing photographs appear in their CAPTCHA puzzles — photos that look very much like zoomed in house numbers taken from Google Streetview.

It appears that Google has decided to put the reCAPTCHA system to help clean up Google streetview images, and "according to a Google spokesperson, the system isn’t limited to street addresses, but also involves street names and even traffic signs."

A large collection of these has appeared on the Blackhatworld website.

So, someone who can't take their eyes off their book is fine, but someone who can't take their eyes off their ebook should be kicked off the flight?

Interestingly, a flight I was on last week (SAS from Copenhagen to Manchester) didn't care about the lady beside me using her kindle. Phones, laptops, etc., all had to be switched off, but her kindle was fine.

I think the slashdot bragging rights were more interesting to him. :)

What an arrogant prick you really are. He replied to your suggestions telling you that they weren't helpful, and that you should just rip the code out. He was right. Your response? You told him to fork VTE!!!! Seriously? A shining example of free-software, this is not.

The only evidence for there ever being such a person is the gospels in the bible. Roman records of Jesus do not exist.

Not true. Look for the history of Josephus -- a Jewish historian writing at the time of Christ (or a little after?) for the Romans.

A lot of the other stuff you wrote is pretty interesting, but I thought you'd appreciate hearing that historical records for Jesus exist outside of religious texts.

Yeah, about two seconds after submitting this story, I realised that I forgot to put a question mark at the end of the title as I had originally intended :(

"Faulty Cable to Blame for Superluminal Neutrino Results?" would have been better, right?

But I was a little more accurate with the summary I think.

Submission + - Faulty cable to blame for superluminal neutrino results->

smolloy writes: It would appear that the hotly debated faster-than-light neutrino observation at CERN is the result of a fault in the connection between a GPS unit and a computer. This connection was used to correct for time delays in the neutrino flight, and after fixing the correction the researchers have found that the time discrepancy appears to have vanished.

Filtering isn't even really for advanced amateurs, since the cost of a filter pales in comparison to the cost of the scope. 20-30$ will get you something that will get rid of most of the low-pressure sodium (orange) emissions. Novices, like me, have a small set of filters they use to improve various views of different objects, and a lot of these filters will be completely defeated by white lights. I'm pretty busy, and prefer to do my observing from my backyard, rather than wasting a couple of hours in a car, so actions like this (replacing easily filtered lights with broad-spectrum ones) is a little irritating.

For astronomers that can actually be worse. For one, if they're not reducing the current through the light to take advantage that more of it is going to its intended target, then the increased reflected light from the street still causes light pollution. More importantly, those white lights emit all over the spectrum, and are incredibly hard to filter out. The ugly orange lights only emit at a couple of frequencies, and is very easy to filter out.

The site they're moving to -- the Gower -- has much darker skies than the glare of Swansea. So, yeah -- they've decided, probably for good reason, that it's not worth paying that much extra for light polluted skies, when they could maintain their costs and increase the quality of their experience.
