Comment Interplanetary Space? (Score 3, Interesting) 166

How much stronger would a field have to be to protect a hypothetical ship the size of the space shuttle from solar winds and other non-EM ionizing radiation in interplanetary space?

If 100 tesla is achievable now, then I can imagine it wouldn't take long before a field can be generated which would be powerful enough to provide a buffer against most ionizing radiation a la Earth's own magnetic field, but I could be way in the realm of science fiction with this thought.

Although perhaps not for daily use, the technology could prove valuable in science experiments

You kidding me? The prospect of GPS-guided bullets accurate to the millimeter will have the US military pursuing this in next-gen GPS satellites as soon as the technology is viable. Hell, this'll be the most valuable update to military hardware in decades.

It's just converting the electricity into light very efficiently with a great ratio

No, it's not even using the electricity to generate light for the most part. The electricity is effectively reducing the remaining threshold needed for ambient heat to be converted to light. In terms of overall energy efficiency, one would find it would still be under 100% if the amount of ambient heat lost could be measured.

Scientists Say People Aren't Smart Enough For Democracy To Flourish 1276

cold fjord writes "The inability of the incompetent to recognize their own limitations is a story that has been covered before on Slashdot. But, what happens when you apply that finding to politics? From the article: 'The democratic process relies on the assumption that citizens can recognize the best political candidate, or best policy idea. But a growing body of research has revealed an unfortunate aspect of the human psyche that would seem to disprove this notion, and imply instead that democratic elections produce mediocre leadership and policies. The research shows that incompetent people are inherently unable to judge the competence of other people, or the quality of those people's ideas. If people lack expertise on tax reform, it is very difficult for them to identify the candidates who are actual experts. They simply lack the mental tools needed to make meaningful judgments...democracies rarely or never elect the best leaders. Their advantage over dictatorships or other forms of government is merely that they "effectively prevent lower-than-average candidates from becoming leaders."'"

Well in my case, I'm taken. Still, I know a few people (cousins, friends, what-have-you) who constantly stress about their height to the point where I've gone from lying about height's irrelevance to them to proposing alternative solutions just to get them to hush a bit. Granted this was back when the people I knew cared more about this sort of thing, but this submission did a good job of reminding me. hah

Comment A theoretical question about height (Score 5, Interesting) 236

There exist treatments overseas for increasing a person's height which rely on repeatedly fracturing leg bones and spacing them such that they heal at a distance, essentially lengthening the bone.

Do we have any osteopathologists on slashdot who can comment on whether this can theoretically shorten such a procedure's duration to make someone taller in a matter of one or two weeks? The current procedure takes at least a few months, if not a year.

Looking at the top of the sphere in the image, it's apparently to me that the image itself is a 3D rendering resulting from many land shots of the Earth stitched together.

NASA readily admits that this is a composite image, but perhaps mentioning that it's a composite of land-pass images stitched together on a 3D sphere modeled after the Earth would make more sense. People might otherwise just assume this is a composite of photographs taken from and stiched together in 2D.

It does make me wonder why the rendering wasn't anti-aliased, though.

Bing Search Overtakes Yahoo 169

SharkLaser writes "Microsoft's Bing search engine has overtaken Yahoo for the first time. While both Bing, Yahoo and a bunch of meta-search engines like the privacy-oriented DuckDuckGo use Bing's back-end, it clearly shows Yahoo's declining market share. comScore has also released its search data for 2011 — overall, Bing gained 3.1% of market share while Yahoo lost 1.5% and Google lost 0.7%. Yahoo's new CEO Scott Thompson has lots of work to do."

They wanted to show that they tried every option, but they didn't actually want to sell Palm.

Why sell it and have someone else potentially give it a heartbeat again? They put it down and kept its assets in the event that they could use the narrowed field to their advantage in deep-diving back into the mobile market in the future.
