+ - A Common Logic to Seeing Cats and Cosmos->

Submitted by Anonymous Coward
An anonymous reader writes "Using the latest deep-learning protocols, computer models consisting of networks of artificial neurons are becoming increasingly adept at image, speech and pattern recognition — core technologies in robotic personal assistants, complex data analysis and self-driving cars. But for all their progress training computers to pick out salient features from other, irrelevant bits of data, researchers have never fully understood why the algorithms or biological learning work.

Now, two physicists have shown that one form of deep learning works exactly like one of the most important and ubiquitous mathematical techniques in physics, a procedure for calculating the large-scale behavior of physical systems such as elementary particles, fluids and the cosmos.

The new work, completed by Pankaj Mehta of Boston University and David Schwab of Northwestern University, demonstrates that a statistical technique called “renormalization,” which allows physicists to accurately describe systems without knowing the exact state of all their component parts, also enables the artificial neural networks to categorize data as, say, “a cat” regardless of its color, size or posture in a given video.

“They actually wrote down on paper, with exact proofs, something that people only dreamed existed,” said Ilya Nemenman, a biophysicist at Emory University."

+ - Nanotube Film Could Replace Defective Retinas->

Submitted by Zothecula
Zothecula (1870348) writes "A promising new study suggests that a wireless, light-sensitive, and flexible film could potentially form part of a prosthetic device to replace damaged or defective retinas. The film both absorbs light and stimulates neurons without being connected to any wires or external power sources, standing it apart from silicon-based devices used for the same purpose. It has so far been tested only on light-insensitive retinas from embryonic chicks, but the researchers hope to see the pioneering work soon reach real-world human application."

I'm sorry, what? You're the one that made the equivalency between gun owners and strippers putting their neighbors at risk. My counter argument was that the gun is dangerous to the neighbors even if nobody knows it is there. It can still be found by a kid, an intruder, go off by accident, intentionally because someone has a mental break, etc. Even without any neighbors knowing it is there. Sure, the stripper is still there too, but If she has a mental break and 'goes off by accident' then you might have a few kids who saw some boobs early in life. Though I admit some would argue that could be pretty damaging too I suppose.
I should note that I'm still assuming in both cases we aren't dealing with 'lowlifes' showing up specifically because of the knowledge of what is in the house.
If we DO assume someone finds out what is in the house, I still see the following scenarios: 1- Lowlife shows up to steal gun. Low life either steals gun and uses it to kill someone, or gets shot by gun owner. 2-Lowlife shows up to accost/molest/stalk the stripper. There is danger to the neighbors, though mostly on the piece of mind front. The DANGER to the neighbors is greater in the first situation.
Not that I'm advocating that the stripper should be sacrificed because of their profession, they don't deserve that even though it is a risk of the job. The gun owner could also be a target, but the mind set of most of the gun owners I know is that owning the gun gives them a way to protect themselves.

tldr; I never once said that the licensing was the problem, I've been arguing against the public release of those records. It's the public release of that information that needs to be discussed and more than a little bit of sense applied to when/where/how it is used.

And finally, back to the alcohol problem. If bars are forced to stop serving at 2, and strip clubs are allowed to serve until 5, it sounds like to me the local laws about serving alcohol need to be addressed to get rid of the loophole. Again, it's not the strippers that are the problem, but the fact that their establishment is getting preferential treatment.

Still not buying that the fact that some people are allowed to dance naked in front of other people being the reason that she died. She died because some shithead got drunk and killed her. Just because he was able to go to the strip club and 'keep on chugging' doesn't mean that he wouldn't have stopped had the strip club not been there. Unless you're saying that the strip club served him the alcohol after normal bars are forced to stop. If that's the case, it STILL sounds like the problem isn't the dancers but the fact that the clubs are allowed to bend the rules on alcohol sales. I'm not trying to say what happened here isn't a tragedy, but pointing a finger at the dancers and saying it's their fault seems to be looking for a scapegoat instead of really looking for the problem.

Getting drunk at a strip club is the same as getting drunk at a bar, or getting drunk at a friends house. If you drive home after, you're still a drunk driver. Hell, in the part of the country where I grew up, the strip clubs seldom, if ever, even sold alcohol.
Also, your equivalency isn't. People KNOW where the strip clubs are, they have signs. People do not know where guns are stored. There are no signs. Just because someone works in a strip club doesn't mean that they take their work home with them. Their neighbors are not at risk, unless some 'well meaning' individual releases the dancer's home address. THEN their neighbors have the issues with the lowlifes you mentioned.

Just because someone has a docorate degree doesn't mean they are an absolute authority. Scholarly papters demand a lot of citations and evidence to be excepted, not someone with a degree saying it is so.

and a doctorate of philosophy in biomedical sciences is such an expert on geology and material sciences.
Just saying, I've seen enough from other sources, the only thing that will convince me that gorilla glass is hardness 9 would be something FROM corning, or from soneone that says 'hey, we tested it, here are the results'. Otherwise it's regurgitated information who's accuracy is suspect.

Further follow up, I have seen around the internet numerous times the claim that Gorilla Glass has an hardness of 9. Most of those claims, however, just like the page you link to, do not cite any references for this information.
However, nowhere in Corning's official literature do they ever indicate ANY Mohs rating for it. They only give the Vicker's rating, and they give it well below what other sources besides the one I linked to give for sapphire

I did some more digging for more places that site the vicker's rating of sapphire, all of them give the Vicker's hardness rating of 2000 for sapphire, still well over the manufacturer's specs for gorilla glass.

Today is a good day for information-gathering. Read someone else's mail file.
