A Beautiful Mind Mathematician John F. Nash Jr. Dies

Posted by samzenpusView
Rick Zeman writes: John F. Nash Jr. revolutionized the mathematical field of game theory and was given a mind that was unique and deeply troubled. He became known to most people by the movie about his life, A Beautiful Mind. Dr. Nash died, along with his wife, May 24 in a two-car accident on the New Jersey Turnpike. The Washington Post reports: "In 1994, when Dr. Nash received the Nobel Prize in economics, the award marked not only an intellectual triumph but also a personal one. More than four decades earlier, as a Princeton University graduate student, he had produced a 27-page thesis on game theory — in essence, the applied mathematical study of decision-making in situations of conflict — that would become one of the most celebrated works in the field. Before the academic world could fully recognize his achievement, Dr. Nash descended into a condition eventually diagnosed as schizophrenia. For the better part of 20 years, his once supremely rational mind was beset by delusions and hallucinations. By the time Dr. Nash emerged from his disturbed state, his ideas had influenced economics, foreign affairs, politics, biology — virtually every sphere of life fueled by competition. But he been absent from professional life for so long that some scholars assumed he was dead."

Soft Sensors Map Skin Mechanics

Posted by samzenpusView
MTorrice writes: An international research team has built electronic, flexible patches that can measure the mechanical properties of skin and other biological tissue. The sensors consist of nanoribbons of a piezoelectric material, lead zirconate titanate, which deforms when jolted with electrical energy and, conversely, produces electricity when it's deformed. The researchers mapped the skin elasticity of dozens of patients in the clinic, building up quantitative data on healthy and damaged tissue. The information could help doctors better assess conditions such as dermatitis and skin cancer. The team believes that similar sensors could be implanted inside the body to monitor blood vessels and other soft tissue for damage or dysfunction.

Universe's Dark Ages May Not Be Invisible After All

Posted by SoulskillView
StartsWithABang writes: The Universe had two periods where light was abundant, separated by the cosmic dark ages. The first came at the moment of the hot Big Bang, as the Universe was flooded with (among the matter, antimatter and everything else imaginable) a sea of high-energy photons, including a large amount of visible light. As the Universe expanded and cooled, eventually the cosmic microwave background was emitted, leaving behind the barely visible, cooling photons. It took between 50 and 100 million years for the first stars to turn on, so in between these two epochs of the Universe being flooded with light, we had the dark ages. Yet the dark ages may not be totally invisible, as the forbidden spin-flip-transition of hydrogen may illuminate this time period after all.

Nerve Cells Made From Blood Cells

They do so by manipulating stem cells that have been taken from a patient's blood, eventually switching them into neural stem cells (abstract). These can then give rise to multiple different nerve cells suitable for use in the rest of the body. Team leader Mick Bhatia said, "We can actually take a patient's blood sample, as routinely performed in a doctor's office, and with it we can produce one million sensory neurons. We can also make central nervous system cells." They're working on turning the neural stem cells into motor neurons for treatment of diseases like Parkinson's and Alzheimer's.

Your competition does get the money though, so you end up with them having an advantage.

I mean this is an effect of giving money only to research that has curing these illnesses as goal. If you do the groundwork, you don't get any money, so you have to do some of the higher level stuff too, which perhaps others would do if grants were fairly distributed.

Software Patch Fixes Mars Curiosity Rover's Auto-focus Glitch

Posted by SoulskillView
An anonymous reader writes: Scientists from Los Alamos National Laboratory have successfully uploaded and applied a software patch to NASA's Curiosity Rover on Mars. The patch fixes a focusing problem that cropped up in November when the laser that helps to focus one of its cameras failed. "Without this laser rangefinder, the ChemCam instrument was somewhat blind," said Roger Wiens, ChemCam principal investigator at Los Alamos. "The main laser that creates flashes of plasma when it analyzes rocks and soils up to 25 feet [7.6 meters] from the rover was not affected, but the laser analyses only work when the telescope projecting the laser light to the target is in focus." Before the fix, scientists had to shoot images at nine different focus settings to distill a decent set of data. Now, they say the new software results in better images in a single shot than even before the laser broke down. The program that runs the instrument is only 40 kilobytes in size.

This fix still requires much of the resources of the previous method, essentially bracketing the shot and picking the best one. This means it will still take just as long to obtain each image, but apparently that wasn't a huge problem. What this saves is something precious though: bandwidth. Now the rover is picking the best shot, instead of sending a bunch of blind guesses and making us sort it out. I suspect that if the bandwidth wasn't precious, they wouldn't have bothered improving on the existing workaround, so it must have been worth all the trouble.

Amazon Decides To Start Paying Tax In the UK

Posted by SoulskillView
Mark Wilson sends word that Amazon will begin paying corporate taxes on profits made in the UK. The company had previously been recording most of its UK sales as being in Luxembourg, which let them avoid the higher taxes in the UK. But at the end of last year, UK regulators decided they were losing too much tax revenue because of this practice, so they began implementing legislation that would impose a 25% tax on corporations routing their profits elsewhere. Amazon is the first large corporation to make the change, and it's expected to put pressure on Google, Microsoft, Apple, and others to do the same.

@FlyHelicopters

I agree to the extent that lots of taxes are simply passed through to customers. If you didn't, you wouldn't be in business for long. And yes, many of those taxes apply irrespective of company size.

But certainly not all of them. As is: different locations have different cost structures. They apply to different aspects of your business. Given the amount of goods that are transported throughout the country, it should be clear that capital costs (cost of setting up production facilities), labour costs, material costs, energy costs, insurance costs, labour productivity, production efficiency, spillage, waste and theft etc. ensure that you get different cost structures in different places.

As soon as you have that, you get a mix of suppliers in one market with different cost structures. As a result you get different profit margins and different tax burdens for different suppliers, and with it different returns on capital. Transaction costs, various constraints, and uncertainty about future costs limit how easily businesses can set up shop elsewhere.

Having a mix of suppliers with different cost structures and different tax burdens wouldn't be possible if taxes were just another cost.

Yes, yes, you think that if I made $1 million in profit last year and the government wants 30% of that, that it shouldn't raise prices. You'd be wrong.

No. The situation you describe is where you total all costs your business incurs, decide how much profit you'd like to make and add that too, factor in any profit taxes, and then charge whatever results to your customers.

That only works if your customers want whatever it is you're selling at that price and there's no-one around to compete with you.

In other words: a niche business.

What you're saying is that all taxes are, in the end, paid by society as a whole (including businesses), which is correct. And yes, if society wouldn't be paying taxes, it would quite simply pay for everything taxes are spent on in other ways, so ultimately all taxes are an expense.

But the fact remains that taxes on products weigh more heavily on individual consumers and taxes on profits weigh more heavily on "capital".

This is simply because an increase in profits will certainly not result in an increase in wealth for individuals that make up the "labour" part of society. They are very unevenly distributed and tend to go towards those individuals who contributed the "capital" part of the equation. Contrarywise, a decrease in profits will not *immediately and automatically* lead to a decrease in wages (and wealth for the "labour" part of society). In both cases "entrepreneurship" is in the way.

To the extent you're saying there's no difference between taxes on products and taxes on profits, that's an oversimplification.

Uhhhh - yes, there is something immoral about tax avoidance. Virtually all of the schemes used to avoid taxes were lobbied for by corporations

Bullshit.

The "loophole" that Amazon has been using is nothing more than the EU single market, in all its glory, exactly as it was intended to be used. The single market was created specifically so companies could set up a headquarters in the EU once, and then sell to the entire trade region without having to register or pay taxes in every single country. This wasn't some clever loophole or corporate scheme, it was constructed, very deliberately and specifically, by politicians that wanted to bring Europe together to avoid another re-run of the World Wars.

When the EU and its predecessors were being set up, governments were all super keen to establish this sort of single market because they saw it as a way to allow their own home-grown champion companies to expand, by selling to people elsewhere on the continent. Paying tax in a single country is fundamental to having a single market, otherwise the paperwork involved with understanding and filling out dozens of tax returns in langauges you don't speak would just be overwhelming. At the time, presumably those politicians didn't care that this meant one day there would be non home-grown companies selling to their people - creating big new companies takes decades and sure enough this "scandal" has only appeared long after the EU was set up and a new generation of companies started moving in.

Regardless, the idea that these companies are grubby scheming tax evaders is pure, unadulterated propaganda. They're doing exactly what they were intended to do - set up a single HQ and sell to everyone from it. The idea that what was once desirable is now immoral is being pushed by the UK media and government to try and distract people from the core fact that there are going to be way, way more cuts and they will be way deeper than anything that's happened up until now. That's not Amazon's fault - the amounts involved are trivial. The fault rests solely on the British people and their leaders.

A lot of things are legal, but not moral. Lying to your best friend, cheating on your wife, pissing in the pool.

On the other hand, there are things that are moral, but illegal, usually because laws change slowly or don't cover all edge cases. Fortunately, many countries have a permissive judicial system where a judge and/or jury can decide that yes it broke the law, but in this particular case it's (morally) right to let it go unpunished.

Methods? They had a large number of factors to correlate with their data: 25 (possibly a few more, depending on what you read), and ran a multiple regression over it, and are reporting an effect for every p .05. That's bad science at multiple levels.

Duru and his business partner "hope to have a new prototype finished by the end of the year and then have hoverboards available for purchase across the country. He wouldn't say how much the prototype cost to build, but said that the first generation of the machine will likely be 'quite expensive.'"

There is little evidence that links crime rates to prevalence of violence on TV or in video games, although there is some evidence that video games reduce crime by keeping young men off the street during their prime crime years (age 15-24).

Perverse

Wanting to watch people die is perverse.

What is worse, watching a person being raped or watching a person being killed? Both wrong, both perverse.

"Hearing 'White cop kills yet another unarmed black man' is enough."

Absolutely not. Cops have been killing unarmed black men for a long, long time. It is only now, when video is frequently available and the media has decided to pursue the matter, that we see a national awakening to the problem. It is hard for most Americans to imagine what it's like to be a young black man living under the control of a brutal police force. We all want to believe that the police are there to protect and serve. It is only when we can see the evil with our own eyes that it becomes real and becomes intolerable.

News Agencies Responsible for Murder and Terrorism

By showing their propaganda videos, it means said publisher is condoning the acts displayed,

No it doesn't. The act of making such videos accessible to others, and approving of the actions within the video, are two entirely different, wholly separate things. You can make the video available without approving of the contents.

But by making it available you take some responsibility for the consequences of the reporting.

A bunch of reporters were kidnapped in the middle east around the Iraq conflict until it stopped being news and became less common. Then soldiers were kidnapped (IIRC in the lead-up to the Israel-Lebanon war) and the Press made a big deal about it, so they started kidnapping more soldiers. The Press shares some responsibility for the increase in soldier kidnappings. Not as much as the people who kidnapped the soldiers, but still some, because *without the press they would not have been kidnapped.*

The same thing is true for school shootings after Columbine.

And the same thing is true for 9/11. Right after the 1993 WTC car bombing, the news media began explaining of course the towers didn't come down *because they were designed to withstand the impact of an airplane.* Osama Bin Laden followed western news about his attacks; this suggested to him the idea of flying planes into the towers. Without media coverage and publicizing the fact that the towers were designed to withstand the impact of a plane, we probably would not have had hijacked planes flown into the twin towers.

News is important; coverage of important issues matters. But coverage of *single events*, when done without regard to the consequences, can cost a lot of lives.

Researchers Devise Voting System That Seems Secure, But Is Hard To Use

Posted by SoulskillView
An anonymous reader writes: According to an article in ReadWrite, a team of British and American researchers have developed a hacker resistant process for online voting called Du-Vote. It uses a credit card-sized device that helps to divide the security-sensitive tasks between your computer and the device in a way that neither your computer nor the device learns how you voted (PDF). If a hacker managed to control the computer and the Du-Vote token, he still can't change the votes without being detected.

Confidence versus rational confidence

By mtrachtenberg • Score: 5, Insightful • Thread

It is conceivable that the World's Cleverest People (WCP) will devise a system that reliably enables people to vote over the internet. And researchers tell us America is no longer a democracy, so I suppose it doesn't really matter that only the WCP will have rational reason to have confidence in the system.

But for those of us who think people should be able to prove to their own satisfaction that their vote was counted as cast, paper inserted into witnessed boxes and then counted in public seems like a better idea. It will never make Microsoft rich, though, so I doubt Microsoft Research will admit this.

KISS

By riverat1 • Score: 5, Insightful • Thread

Voting should be a low tech process that anybody can understand. Too much technological magic erodes the trust of voters who are capable of understanding it. Simply marking a ballot with a pen is understandable by anyone. Maybe you count them by machine but you always have the fallback of machine counting. I don't trust any voting process that doesn't have that fallback option. If the voting records are only held electronically how can you ever completely trust the results haven't been hacked?

Beside hacking

By AchilleTalon • Score: 5, Insightful • Thread

Beside hacking a device to steal votes, there is a number of other concerns about the online voting which cannot be eliminated by any device you can imagine.

For example, how can you be assured the voter has not sell his vote and the buyer can just sit beside him to make sure he is getting what he paid for? How can you prevent someone to impose a candidate to someone else by threatening him/her/them? At a vote poll, you can make sure nobody is intimidated and anyway there is no way someone else can check the vote he tried to steal.

Online voting is a big No-No.

If I wanted ritual in my life, I would have become a priest and pursued my career with extreme political ambition so I could vote for the freaking pope.

I guess you've never read an article in your life about mobilizing the voters who are too lazy (or metabolically downtrodden from their Cheetos and Coke diets) to physically show up at a polling station?

Paper is a physical token. Reliably obtaining exactly one unambiguous, untamperable physical token with confidentiality from each adult member of society—the vast majority of which are collected on the same day—hasn't exactly proven to be an easy problem, especially when broadened to include public trust—that every voter understands and believes the process to have all of these properties (to at least a substantial degree).

Electronic voting vastly reduces the complexity on the collection side, but then the tamperability problem looms supreme, but this could almost be solved with enough crypto cleverness, except that the public trust story then requires a tiny bit of numeracy beyond grade six math.

Ritual, however, is accessible to a four-year old.

The same four-year olds who are unfortunately not yet equipped with fully functioning batshit detectors.

I don't want to abolish ritual. I simply want to reduce it to the size where I can drag it into the bathroom and drown it in the bathtub.

Proctored voting

By Okian Warrior • Score: 4, Insightful • Thread

A lot of people think online voting is the next big thing, but the problem is actually very hard to do online.

To do it right requires a "proctored" setting where the person is guaranteed to be alone, and unobserved (including video recording).

If you can't guarantee that the person is alone, then they can be coerced into voting a specific way. If you can't guarantee that the person isn't observed, then the person can sell their vote.

Video recording hasn't been addressed yet, but with the current system a voter can record their vote as proof of how they voted, and so vote selling is possible. It's functionally the same as being observed, just time shifted.

Add in the requirements for recounts and verification, and physical ballots in a proctored environment is the simple solution.

I've seen mathematical solutions that make tampering statistically impossible. The system injects a large portion of non-human votes in a cryptographically secure way such that it doesn't change the actual outcome, but it's impossible for a hacker to change votes due to the statistical likelihood that he'll change one of the non-human votes and be detected.

Even with these systems, you still need a proctored environment that guarantees anonymous and unobserved voting.

New 'Deep Learning' Technique Lets Robots Learn Through Trial-and-Error

Posted by SoulskillView
jan_jes writes: UC Berkeley researchers turned to a branch of artificial intelligence known as deep learning for developing algorithms that enable robots to learn motor tasks through trial and error. It's a process that more closely approximates the way humans learn, marking a major milestone in the field of artificial intelligence. Their demonstration robot completes tasks such as "putting a clothes hanger on a rack, assembling a toy plane, screwing a cap on a water bottle, and more" without pre-programmed details about its surroundings. The challenge of putting robots into real-life settings (e.g. homes or offices) is that those environments are constantly changing. The robot must be able to perceive and adapt to its surroundings, so this type of learning is an important step.

That strikes me as the sort of thing that would be "hardwired" in everything from nematodes to primates. Why is this news?

Because it isn't a nematode or a primate. It is a robot. A living thing that can learn and adapt is not news, because that's what living things do. A non-living think that can learn and adapt is news because that's what living things do.

Re:"Deep Learning"...??

It is a good question, and there are several answers...

Artificial Intelligence has been seen as a goal since Ada Lovelace was a lass. In the fifties, it was hoped that computers fed with parallel translations could learn the rules of languages, and provide fought translations of (say) technical documents on aeronautics from Russian to English, where sufficiently skilled and positively vetted engineers were rare. There were later attempts in the sixties and seventies to learn to walk, recognise objects, or solve puzzles. There was the constant hope that the next hardware would be a bit more powerful, and you could throw problems at it, and intelligence would somehow boot up. After all, that is how it must have started last time. However, intelligence failed to boot up, or maybe it always lost out to other brute force techniques which regular computers are good at.

The nematode has a simple. pre-programmed brain. It is good for being a nematode, but it doesn't really learn. Our brains have a lot of structure when they are formed, which means that our language centres, our vision centres, the parts that are active when we are solving spatial problems, or composing music, turn up in the same places most of the time; but we don't seem to run an actual program as such. We are born with very little instinct when compared to most other complex animals, but I suspect even they are not really running a program either.

The trick seems to be to provide the robot with enough plastic design to nudge it in the general direction of intelligence: too little design and it never gets its act together, while too much design means it is just doing what you programmed it to do. There are interesting times where computers are getting the complexity and the connectivity and plastic re-programmability to rival animal brains; but the spontaneous self-evolving problem solving spark just isn't there yet. But I hope we may see it in our lifetimes.

An automaton can be neither benevolent nor have free agency.

Why not? Unless you believe that brains are magic, or created by the intervention of a deity, there is no reason to believe that computers have any inherent limitation that living things do not have.

Hmm... sorry, this has been happening for many years already... back to the 80s... This is nothing new.

No, it was not happening in the 1980s. The fundamental algorithm behind deep learning networks was worked out by Geoffrey Hinton in 2006. Before that, training a NN more than 2 layers deep was intractable.
