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.

Having read all the nominees, I think this was not a very strong year. I liked Feed, but I'm sick of zombie novels (and so is everyone else). Cryoburn is (I believe) Book #16 in the Vorkosigan series, and though it's well-executed, it doesn't stand out from the other 15. The Hundred Thousand Kingdoms is fine, but it suffers from a bit of debutnovelitis. I would have picked either The Dervish House or Blackout/All Clear, and apparently The Dervish House is so little known that it doesn't even have a Wikipedia page.

I disagree about the Hugos being hidebound, though - look at the last three years, with The City and the City, The Graveyard Book, and The Yiddish Policemen's Union all winning - none of which are conventional science fiction at all.

N.B. - Connie Willis won her first Hugo in 1983, and has two previous Best Novel wins. There's some good science fiction in the last 25 years, you might want to look into it. (This year's Hugo class of novels wasn't that strong, though - so don't start there).

E-ink products will not serve your needs. I'm a grad student in physics, and I tried doing exactly this. I love my Kindle for reading books, but the delay and screen size issues (even on the DX) made reading technical papers, where I often am moving back and forward quickly, frustrating. This leaves aside the difficulties of organization - ereaders are not really designed to have 200+ papers. I suggest getting a tablet instead - the ability to download new papers directly from the tablet is worth the additional money.

Math trick slash analogy. In graphene, electrons behave like massless particles traveling near the speed of light. What this means is that energy increases linearly with particle speed, rather that KE = 0.5 m v^2 , like you learned in physics 101. Particle physics people have argued that adding compact dimensions (rolled up) will change interactions, and these guys have showed that you can also get electrons to act like massive relativistic particles in tubes of graphene. I'm not an expert in the field, but this seems to be a little buzzword-heavy, rather than really groundbreaking. As far as I know, the connection between graphene and relativity had not taught us anything new about relativity, or how mass is generated, but it is kinda cute and gets headlines.

There are also some particularly strange choices for the overlaps of mathematics and physics. Einstein, for instance, wasn't pioneering new mathematical methods for the most part, but links the math and physics lines. Then Ed Witten, the only physicist ever to win a Fields Medal, isn't connected to the math line.

Also a problem: where's Ken Wilson in modern physics? Renormalization group ended up simultaneously revolutionizing particle physics and condensed matter physics - I can't think of a comparable example in the last 40 years or so, aside from the rise of computational methods.

Comment Re:Whatever The Party says (Score 5, Insightful) 645

Okay, let's turn down the rhetoric a couple of notches. There are two aspects to this -

1) This does not appear to be a case where the publisher just "changed their minds." 1984 and Animal Farm are, through the usual idiocy, under copyright in the US but not in other countries, so someone re-publishing the text without paying the copyright licensing is breaking the law, and Kindle customers have, in effect, been sold "stolen" property. (Equivalent: buying software that illegally includes GPL code). If you buy a stolen ipod, it can get confiscated by the police.

2) However, this does reveal a pretty worrying tendency to kill books first, clarify later. If Amazon had just sent out refunds, plus notes that "Due to an oversight, if you are in the U.S., this version of 1984 is unauthorized," that would have seemed sensible.

My suggestion - use the Kindle if you like (I love mine), but backup your books, strip the DRM, and pirate shamelessly. Casual piracy adds features to ebooks - the ability to lend and trade books, which is how we all got hooked in the first place.

Tossed a coin between moderating and replying. Doomsday Book is excellent, but I think Connie Willis's To Say Nothing of the Dog is much better (and also laugh-out-loud funny). Timeline isn't terrible, but it suffers from a plot hole so obvious it pretty much spoiled the whole thing for me - if they travel to a parallel universe, how does an object they sent back in time show up in the present?

I think part of the worry comes from a mistaken belief that each treatment will mean the destruction of an embryo - hence the "vampirism" fear. Maybe I'm wrong in this, but the treatment comes from a stem cell line - i.e. once upon a time there was an embryo, and now it's billions and billions of constantly growing individual stem cells. Objecting to stem cell *treatments* because of embryos being destroyed is like a vegan refusing to be treated by a doctor who once ate meat ten years ago.

This is part of the Gates Foundation's system of high-risk, high-reward research: take the smartest people you know, ask them to come up with crazy ideas, and see if any of them work. This one did. And though Lowell Wood gets credit for the initial idea, the laser scientists "...teamed with an entomologist with a Ph.D in mosquito behavior and other experts."

Lowell Wood is known for coming up with creative solutions to big problems - he might be a little crazy, but it's the kind of crazy we need to make sure we keep on trying new ideas.

I recently subscribed to Analog. I started every story in the first issue, and only one was worth finishing. Most either failed to 1) have believable, interesting characters, or 2) realize that new words are not new ideas.

But that doesn't mean science fiction is dead - read the Hugo-winners and noms. Books like Rainbows End (Vernor Vinge) and Spin (Robert Charles Wilson) have restored my faith in the genre. Maybe I'll give Analog another chance, but right now there are too many good novels out there.
