Comment Re:For fuck's sake, not string theory! (Score 1) 192

While I generally agree with you about the esoteric nature of string theory, I should correct the record on supersymmetry and inflation (I know you didn't complain about inflation, but it's there further up the thread).

Supersymmetry is an idea with some fairly strong motivations that has driven the last several decades of experimental work in particle physics - there is not solid evidence for it yet, but it is not ruled out. Some of the simplest variants have, however, been ruled out. Here's someone more representative of the experimental particle physics consensus at the moment: http://profmattstrassler.com/articles-and-posts/some-speculative-theoretical-ideas-for-the-lhc/supersymmetry/where-stands-supersymmetry-as-of-42012/
(Should we be giving awards for theory that is not yet proved, but has motivated and clarified our understanding of particle physics? Maybe not, but supersymmetry is definitely not ruled out.)

As for inflation, there is a reasonable amount of experimental evidence to support it; I know fewer astro people, but I would not describe inflation as unsupported, or even necessarily that controversial. http://en.wikipedia.org/wiki/Inflation_(cosmology)#Observational_status

Unfortunately, no. Many intelligent young students are already going into high-energy theory and string theory (the primary recipients of this prize). In fact, there are far more students than jobs. I'm a recent PhD from a top physics (and particularly string theory) school. My classmates in string and high energy theory who recently applied for postdocs applied to 100 in order to receive 1 job offer; none of their jobs were in the U.S. These are not permanent jobs; they are usually 2 or 3 year positions, paying $40,000 or so. At the end of this time, you may then enter the lottery for the (literally) one string theory faculty job per year (see http://www.math.columbia.edu/~woit/wordpress/?p=4701 for job statistics). This is what causes students to leave to go to Wall Street, and piping in more money to the already-established best of the best of the field will not change this.

The purpose of this award seems to be to raise the profile of so-called "fundamental" theoretical physics; perhaps it will cause more funding to be directed in that direction, which might be good. More likely, it will simply encourage more optimistic, talented students to step into the meat grinder of a particularly depressed job market, making it even worse, and eventually redirecting another generation's best minds into Wall Street.

I'm not saying don't celebrate physics (I love physics, and am continuing in the field, though on a much more applied topic, where there is more funding) - but there is already enough hype for string theory, and it burns out enough students already.

While ice cream makers have probably done lots of experimentation, simulations like this (in addition to being cool physics for other reasons) can give us new directions to look in - e.g how should we change the emulsifier used. More fundamentally, what are the controlling factors for the failure of ice cream? Since TFA is a press release, you can get a better taste for the work the Edinburgh group does from their papers - a related one is at http://arxiv.org/abs/1203.0410

I should also pitch this group's work more generally - Michael Cates' group does a lot of cool simulation work on the dynamics of liquid crystals, as well as active fluids, such as swarming tanks of bacteria. Most of it is on the arxiv, http://arxiv.org/find/cond-mat/1/au:+Stratford_K/0/1/0/all/0/1 and http://arxiv.org/find/cond-mat/1/au:+Cates_M/0/1/0/all/0/1

Some of the behaviors of fluids with active objects (bacteria or molecular motors) are quite unintuitive - if you try to push a sphere through one of these active fluids, it will sometimes go in the opposite direction of the force you apply to it! http://arxiv.org/abs/1204.1279

(I am a soft matter physicist, but not from this group.)

So what does it take to get a permanent position doing particle physics these days? I'm a newly-minted physics PhD (different subfield, though), and the job market seems fairly moribund.

That said, my classmate who's going into the financial industry is probably going to be paid 300% what I do as a postdoc, and I wouldn't even consider it.

Here's another German-language article on the topic: http://www.dradio.de/dlf/sendungen/campus/1802360/

My German is a little rusty, but none of these articles seem to address at all how students typically pay, and whether the tuition/credit-hour distinction is all that relevant. On the other hand, since the Prorector they got to comment said something as stupid as, (loosely) - "If you drink a Coke twice as fast, you don't get to pay half price," and invokes the "not fair to other students" approach, it doesn't sound like the school has a particularly strong case.

'Legitimized' Cyberwar Opens Pandora's Box of Dirty Tricks 134

DillyTonto writes "U.S. officials have acknowledged playing a role in the development and deployment of Stuxnet, Duqu and other cyberweapons against Iran. The acknowledgement makes cyberattacks more legitimate as a tool of not-quite-lethal international diplomacy. It also legitimizes them as more-combative tools for political conflict over social issues, in the same way Tasers gave police less-than-lethal alternatives to shooting suspects and gave those who abuse their power something other than a club to hit a suspect with. Political parties and single-issue political organizations already use 'opposition research' to name-and-shame their opponents with real or exaggerated revelations from a checkered past, jerrymander districts to ensure their candidates a victory and vote-suppression or get-out-the-vote efforts to skew vote tallies. Imagine what they'll do with custom malware, the ability to DDOS an opponent's web site or redirect donations from an opponent's site to their own. Cyberweapons may give nations a way to attack enemies without killing anyone. They'll definitely give domestic political groups a whole new world of dirty tricks to play."

Notepad? Seriously? I mean, I can understand not wanting to use a GUI editor since they all suck, but you're only hurting yourself if you insist on using the second most primitive tool available. (Why not go the whole hog and use EDLIN?)

There are a whole load of things in between that provide conveniences like indentation, tag/attribute completion, on-the-fly validation, etc while still letting you write the HTML yourself the way you want it. You should be using one. It will make you more productive and increase the quality of the web pages you produce; and if you are really refusing to do so, then you, sir/madam, are no more a professional than a "carpenter" would be who insisted on planing wood with a sharpened screwdriver.

What's the problem with that?

It is 2012, not 1962. Am I seriously reading someone asking what the problem would be with disenfranchising "impoverished and minority voters"?

A few of the poor might be civically involved and responsible, such as yourself.

"I say, boy! You are not like those other poors who are all lazy and stupid! Well done. Have a pat on the head."

But on the average, poor people have been shown to have bad decision-making skills.

By whom? Citations please, preferably to studies that show that middle- and upper-income people are significantly better at making decisions. (Because it sure looks like a lot of rich folk have made some pretty shitty decisions recently. It wasn't poor people who invented subprime mortgages!)

Or do you mean that it's self-evident from the fact that they're poor? Because that would be your privilege talking, not your brain. It is not, in general, straightforward to pull oneself up by one's bootstraps. Being able to make good decisions doesn't help if none of the available options is good.

Also, "minority"? Are you serious?

I don't know about hir, but I am. Yes, of the people receiving state support in the USA today, proportionally more are from minority backgrounds, and skewing the voter pool in favor of the majority ethnic group would be a problem.

You're playing the structural racism card, and that's not a healthy way to play.

Why not? Structural racism is a thing. Pointing out that the policy you are advocating would be a terrible idea because it would disproportionately disenfranchise people who already suffer from the racism endemic in this nation is hardly unhealthy. It's ignoring the problem that would be unhealthy.

Oh no, we can't increase our standards, or else a group that is disproportionately represented in the lower score will be disadvantaged.

Come back and try this argument again when you have a shred of evidence that shows that letting poor people vote is bad for democracy.

Oh, and you're a racist, because the only logical conclusion of your argument is that white people are smarter than any other race. Burned any good crosses lately?

Played one way, why can't they be like Asians, who suffered prejudice and came out ahead?

"Gee whillikers them yellers sure are smart, ain't they? Damn good at math I tell you! And they work real hard, not like those lazy nigfood stamp recipients! Nosiree I am not racist what made you think that."

Played another way, why don't we extend the franchise to undocumented Hispanics, who may have just as much stake in our country as we do?

Good idea. Why not?

ultimately these restrictions serve no real purpose and just waste a lot of money in the form of time lost by both IT, administrative and research staff.

I'd be interested to see what evidence you have to support this claim. Dealing with e.g. the malware infestations and DMCA threats inevitably caused by people taking advantage of a network not blocking sketchy websites would probably also waste a lot of money and time.

Are you really claiming that there are more researchers legitimately investigating porn websites than there are horny frat boys who just want to jerk off in their dorm rooms and then steal a movie for later? More software companies who have not figured out a better way to deliver their product than emailing it to random employees than random employees who would install every "screensaver" emailed to them by a criminal? Really? Because that sure sounds pretty implausible to me.

Random Online Comp Shop Inc. isn't going to get the volume license discount that Dell/Lenovo get for shipping millions of licenses

See my post below. HP considers the additional cost of an OEM Windows license to be US$75 (Home Premium) or $100 (Professional).

Last I checked, HP was the single biggest PC manufacturer in the world. If there's a good volume discount going, I'm guessing they get it.

Now, maybe HP don't add as much crapware as more consumer-focused OEMs. But, well, I don't know how much the shovelware authors pay for each installation, but I really doubt it's more than a few dollars at most per program, and even Dell doesn't ship that many programs. They won't be offsetting a full $100 by any means. That, my friend is why the Microsoft tax is a real thing that costs real people real money if they don't want to use Windows. And that's terrible.

Does anyone honestly think that retailers would charge you $50 less (or whatever the cost of the Windows License is, probably closer to $15) if Windows wasn't installed?

Well, how about we ask the retailers?

I am looking right now at HP's "configure your laptop" screen in their online store.

The OS selection options they are offering me are:

  • Genuine Windows 7 Professional 32 [add $0.00]
  • Genuine Windows 7 Professional 64
  • Genuine Windows 7 Home Premium 64 [subtract $25.00]
  • FreeDOS [subtract $100.00]

So, if you are right - if the cost of a Windows license is just $15 or so, there is no Microsoft tax, and computers are subsidized by Windows-only crapware - why is HP willing to refund me $100 on the spot if I choose not to have Windows?

I await your explanation with interest.
