Submission + - Driving Force Behind Alkali Metal Explosions Discovered (nature.com)

Kunedog writes: Years ago, Dr. Philip E. Mason (aka Thunderf00t on Youtube) found it puzzling that the supposedly "well-understood" explosive reaction of a lump of sodium (an alkali metal) dropped in water could happen at all, given such a limited contact area on which the reaction could take place. And indeed, sometimes an explosion did fail to reliably occur, the lump of metal instead fizzing around the water's surface on a pocket of hydrogen produced by the (slower than explosive) reaction, thus inhibiting any faster reaction of the alkali metal with the water. Mason's best hypothesis was that the (sometimes) explosive reactions must be triggered by a Coulomb explosion, which could result when sodium cations (positive ions) are produced from the reaction and expel each other further into the water.

This theory is now supported by photographic and mathematical evidence, published in the journal Nature Chemistry. In a laboratory at Braunschweig University of Technology in Germany, Mason and other chemists used a high-speed camera to capture the critical moment that makes an explosion inevitable: a liquid drop of sodium-potassium alloy shooting spikes into the water, dramatically increasing the reactive interface. They also developed a computer simulation to model this event, showing it is best explained by a Coulomb explosion.

The Youtube video chronicles the evolution the experimental apparatuses underwent over time, pursuant to keeping the explosions safe, contained, reliable, and visible.

Comment Case in Point - KOMO's Gamergate Story (Score 1) 267

That explains why many news organizations are removing the ability to comment from their sites: because it was undermining the effectiveness of the favored propaganda they pass along as 'news'. Remember kids, journalistic bias is all about WHICH propaganda you decide to go to press with.

Yup.

Just last week, KOMO TV in Seattle aired a biased Gamergate story (though, as a sad indication of how low the bar is, it's way less biased than most news media). Three days later, there was a note at the bottom of every story, saying site comments are no more:

Looks like too many gamers were fact-checking their work, and it was too embarassing to let people see that happen.

As long as they can remain undetectable from beyond the range of their nuclear warheads*, they will be indispensible. You should even be glad your enemies have them, as they are one of the most stabilizing technologies because they discourage first strikes (by guaranteeing a second strike).

Comment He didn't say 1st Amendment (Score 1) 400

Sorry to burst your tea party bubble, but freedom of speech only applies to government actions.

No, the First Amendment only applies to government actions. It may be hard for you to believe, but some of us find virtue in protecting freedom of speech even in cases where the law would let you get away with suppressing it.

Dunno why you'd bring up the tea party or twitter, but it is interesting that this story and last week's twitter story both neglected to use the censorship icon.

Comment More Than a Cause of the Moment (Score 2) 467

One of the most important reasons Gamergate hasn't died is that it exposed (as part of coordinated effort to stomp it out) forces with an apparent willingness and (more shockingly) ability to successfully censor vast swarths of the internet, including sites like slashdot, reddit, and 4chan that were taken for granted as free-speech strongholds.

Of course people are going to care now that they threaten Twitter, which has been second only to Youtube as a major thorn in the censors' sides.

Comment It Remains a Journalism Scandal. Deal With It. (Score 2, Insightful) 467

The cover-up didn't work.
The week-long gaming press news blackout and user comment/forum censorship didn't work.
The coordinated, ongoing smear campaign that began with the "Gamers are Over" articles hasn't worked.
The doxxing and harassment of pro-GG folks hasn't worked.
The endless train of embarrassingly desperate counter-hashtags hasn't worked.
The Wikipedia and Nightline hit pieces only damage those outlets' credibility for short-term effect.

PC Gamer is the latest games journalism site to update its ethics policy in the wake of Gamergate, joining IGN, the Escapist, and of course Kotaku/Gawker (though in Gawker's case, they put up more of a fight and the Gamergate pressure to be ethical had to be routed through the FTC). And there are probably more I'm forgetting.

Gamergate also got Brad Wardell (CEO of Stardock) some long-overdue apologies for hit pieces run against him:

Ask yourself how much of this you've seen reported in the corrupt media (which at this point, sadly, clearly includes Slashdot). Of course none of it ever had a chance of appearing in the Wikipedia article. Nothing enrages anti-Gamergaters more than someone covering both sides of the story, and that should tell you something.

Their side thrives only in an environment of propaganda and censorship, and evaporates when faced with integrity and transparency. They prove the need for Gamergate every time they write an article based on the assumption that terrorism and child porn^W^W^W^W misogyny and harassment have become the root passwords to the Constitution^W^W journalistic ethics.
