Actually, that's easy, and has been done: http://arxiv.org/abs/1203.2847

(Full disclosure: I'm an author on that paper)

Modulation (strictly speaking) isn't required. To make the system work, you only need semi-reliable one-bit fast communication, and slow communication otherwise. On the slow channel:
"I'll be ready to send a neutrino pulse at 12:00:00.000000"
"Send me a neutrino bunch at 12:00:00.000000 if it would be profitable to buy "
Then the beamline simply pulses or doesn't-pulse the beam at that time, depending on the financial data of that instant. It's basically a matter of firing or not-firing the extraction kicker magnet that pulls the protons onto the target that makes neutrinos.

Of course, the article under discussion about financial communication is a complete parody, obviously written to suck in gullible financial types. It doesn't actually lie - the system could be made to work, no problem - it just conveniently discusses only the cost of the receiving unit, not the 'sending' unit. The sending unit costs rather a lot more, which isn't mentioned in the article, and can't be aimed.

Basically, it's a cynical and amusing attempt for the neutrino physicists to try to get the bankers to buy us the beamline we want for purely scientific purposes. A more nobel cause cannot be imagined. ;)

This sort of comment is so arrogant, I have to call foul.

Are you an educator? Then why haven't you done this yourself? Why isn't education revolutionized as we speak?
Are you actually ignorant about how to teach? Then maybe you should learn about it before proclaiming yourself an expert.

Teaching is fundamentally about one and only one interaction: a teaching talking with a student. Notice the word "with": although some teaching can happen with one-way transmission, it's not effective. Humans learn through iterative processes of getting challenged, making mistakes, getting feedback, changing, improving, perfecting. This happens at every stage, even in the course of a five minute lesson or lecture.

Even when I am teaching college students, in a lecture setting, there is a LOT of two-way communication. I can tell when they don't get things. I can ask them questions to see how fast they respond. I can see them nod or frown. I can see them stare at their laps, smiling (which means they are texting instead of thinking). I can walk between them and look over their shoulders. They can ask questions. They can see my enthusiasm. They can participate in groups or singly.

Teaching is about conversation. Although there are ways of having meaningful conversation with 2,5, 10, even 20 people, the effectiveness of that conversation drops as the group sizes get larger, until you are in the 200 person lecture hall and the conversation becomes almost unidirectional.

Speaking as a scientist, whenever you see an article refer to "scientists" without any attribution, the best policy is to ignore it. Credit the specific person or group. "Scientists" are not a cohesive whole who all agree on everything, and this statement is almost assuredly not consensus opinion.

As to the content:
"Indeed, it has been said that democracy is the worst form of government except all those other forms that have been tried from time to time."
--Winston Churchill

At least, that's the basic idea behind both Google and other engines: show results that aggregate the opinions or outlook of many people. Authoritative links are ones which many people use, useless links are one that no one uses.

The whole thing with Santorum is that, actually, there is a very large segment of people that despise what he stands for. This group is at least competing with (if not more powerful than) the population of people that think he's a sane politician worth listening to.

The disconnect here is mass media. According to the rules they have adopted, candidates are to be taken seriously when they hit a certain (small) proportion of support, at least if they are right-wing candidates, and open mockery or confrontation are simply not done. Hence, Santorum is a "real candidate" and shouldn't have this level of opposition.

But that's not reality. I agree: a disclaimer would implicitly say that the voice of the people is political... which is rather obvious and useless, since it's always true.

This is indeed the problem I see teaching introductory physics at a small college: students are smart, students are hard-working, but they don't have either the technical or study skills they need.

If there were better prepared in STEM fields, they wouldn't have as far to catch up in their first year, and so the "death march" would be substantially easier.

If they were better prepared to be challenged, to accept intellectual problems of much larger magnitude than they have seen before, then they would also be OK. They would know how use their hard work instead of revving in neutral, madly reading and re-reading textbooks they don't understand.

There are lots of things we can do to teach better, but all of those things require time, in class and out. We can't just 'make time' to do them: that would leave an undergraduate student without a complete education. (For example: we could cover only half of the topics on the MCAT, so future doctors would need to take twice as long learning science requirements, delaying their medical school by years and driving up their debt load.)

So, it took them 1 week to come out with an update to patch their browser? That doesn't seem an egregious delay to me. I haven't yet patched any of my other browsers yet. I'd be surprised if most users patch within the week of bugfix releases anyway.

And if I understand it, this "security hole" is basically that you won't get bad-certificate warnings if you visit certain fraudulent sites... which isn't likely to happen unless you're clicking links in phishing emails.

This hyperbole about apple being slow seems like hot air to me.

Apparently my cheap-ass university doesn't have download rights to the original article in Neuroscience, but my guess is that the weak point is in the paper-and-pencil questionarre. The problem is that they aren't asking people how often they get distracted... they're asking people how often they _remember_ getting distracted.

An equally valid hypothesis is that big-brained people remember getting distracted more than small-brained people.

Again, I haven't RTFA so maybe they deal with it. They talk about inheritability of the 'distraction' scores, but that just means that it's something either genetic or social. In fact, there could instead be a correlation between 'big brained' and 'more honest'.

The only power of theoretical models is in making predictions. If I can can consistently predict the outcome of a set of experiments, you can trust that my theories are not wrong. You can never prove a theory right, of course. But you can throw so many tests at it that you can be sure that it's not completely wrong - and any contradictory evidence that comes forward will only modify your theory, not expunge it.

You don't have to understand wave mechanics to believe that it works. You can ask a theorist to predict what happens when you put two slits in front of a laser. They make a prediction, and then you see it. You don't even need to see it yourself. You can trust people whose job it is to look at things, just as you trust that books and newspapers haven't invented whole continents out of fantasy.

We can make transistors. We can make them very well. This shows we understand the principles of transistor-making, which we call quantum mechanics.

This is either stupid or a troll - yet another attempt to build a false equivalency between proven methods of finding out the truth, and unproven magical thinking.

Unless you want to wait a few millennia for alpha decay to replenish our supply, there simply won't be anything like this... at least not for more than a few years. We are foolishly squandering our remaining supply.

I'm rather fond of the low-end Tek scopes. The LCD screen is a little slow, and there's only 2 channels, but these are not huge limitations for most basic work. I use these teaching physics and intro electronics to undergraduates - they're easy to use, lightweight, and can store data through USB or pen drives. 100 MHz for about $1200, which is OK for general use.

I have done this from Beijing and it worked the week I was there.

FoxyProxy is a nice add-on to use for this, since it allows you to either whitelist specific sites for use through the proxy, or to simply switch back and forth to the proxy as you need.

There's already a better method, which doesn't kill liquidity (as some have suggested below)... simply put a microtax on all stock transactions of less than a percent.

Even this super-AI is going to make mistakes - it's profit margin is not likely to be large on the _average_ transaction, to microtaxes like this will keep this sort of activity to a minimum. Lots of people have suggested such a tax.

Basically: this sort of transaction does NOTHING for the economy except leech money from the people that actually produce things. Wall Street, as a whole, has a purpose: allocation of capital to build the economy. But there's no reason that people working on Wall Street should make more money than other facilitators or utiilities of our system, like payroll accountants or garbage collectors. The only reason they do is because we let them.

Yes.. for people. But not necessarily for organizations.

Of course, making such a distinction will require reversing a very old (and recently reinforced) precedent in US law, where organizations have personhood. Probably requiring an amendment. So it won't happen.

Seriously? Keep your notes in a book or some other time-ordered form. Pretty fast to flip through, find things before and after the stuff in question. Basic indexing (putting a two-letter abbreviation at the top of each page by topic) makes it even easier.

The human eye is remarkably good at picking out visual subject material. If I've read a pure-text book, I can usually flip to a section I remember faster than using the index. Pure computer-based searches are useful mainly in contexts where you _haven't_ read the source material before, but that's not the application we're discussing here.
