nature does not write articles - articles are submitted for peer review from the original authors - nature is a publisher of others' work, not an original contributor to scientific journalism - same w/ science, prl, apl, etc.
something like scientific american or pop. sci. 'dumbs down' the material for layman, but that usually comes later after the peer review journals have their fix.
not really... ZnO is a II-VI semiconductor, while the other materials you're talking of are III-V conductors. there are many other room temp 'spintronic materials' such as ZnO:Co, TiO2:Co and so on. this is just another in a list, although promising. my lab has made room temp DMS of ZnO:Co (goes up to greater than 75C, and publication is in process... but any news is good news when you're in a relatively new field
at this 36000km mark, would be the center of gravity for the cable itself (and elevator)... so the counterweight in space needs to only equal the weight of the earth side cable and machinery. the reason they put it 1/3rd of the way along the cable is so that less weight needs to be lifted into space to act as a counterweight (16.7% less?). additionally since the cable in space does not need to support its own weight, only the tension between the counterweight and the center of gravity, it does not need to be as strong, requiring less material.
i've used weight instead of mass, because well, thats what most people understand in the vernacular, so don't bother flaming me about that.
That is a load of crap. My advisor (just for a start) will not take any DOD $, although NIH, NSF, DOE money is fair game. I would say that only half of the advisors in my department ever have accepted DOD $, the rest refusing.
It seems about the same with other departments/schools as far as I've spoken. The exception being $ coming indirectly (naval research lab and DOD paid for a trip to europe for me).
However, any worthwhile advisor would allow a student to pursue their own funds, and if I want to apply for a DOD fellowship, my advisor will support me completely.
But I think it is a bit foolish to say that most scientists are taking military money due to the perceived threat. If anything, their proposals are worded such to give the impression of being realted to homeland security while simply obfuscating within, the true research they want to do.
The Indians I know, fresh off the boat or been here for 20 years) tend to speak english clearer and more intelligently than most americans I know. and they can certainly write clearer english than the americans i know.
well, this is one article about one idea. there are many more facets of magnetism research. i'm working on diluted magnetic semiconductors that put ~1ppm magnetic dopant into a semiconductor... this can conceivably allow for solid state, non-volatile, always on, (insert your term), memory. perp. recording has been around for a while, just not economically feasible, and who knows when it will be.
there is no company who is reaching 1terabit per cm2, as there is something called the superparamagnetic limit
As i read that i instinctively reached to the back of my neck to feel for any signs of scaring - I just got an ibook in janurary and have used/owned macs for 15 years. i felt small bump and thought no, it can't be.
so i ran around like a dog chasing its tail, trying to look at the back of my neck - until i ran to the bathroom and used the mirror.
alas, no sunflower tatoo, it was a small pimple. (well, this is slashdot)
Those aren't really related. When you're driving, you look in front of you, and at the spedometer. You rarely look at the battery gauge (maybe once a trip if you're concerned) but nevertheless, the information is there, easily accessible if you need it. The stuff to the right and left of the/. main page is there, easily accessible if you need it. I use parts of it fairly often for various reasons (and i don't spend all that much time here) and appreciate its layout.
However, a presentation DOES need to present the minimum of information or you crowd out the point of the presentation - but a well laid out presentation will cite sources handily (bottom of the page, small print) or the presenter will provide additional/relevant information if necessary in some other format.
Well, apple is opening a new store in the university village shopping center, just east of the U of washington. it is slightly more than 1 mile directly east of Seattle's "the mac store" (formerly the computer store)
The bellvue apple store opened 2 weeks ago, and this u village store will likely open around christmas time. So, apple's respect for them isn't all that great.
Having just moved here, and having spent lots of time in cupertino, i look forward to the apple store nearby - the mac store is ok, but their sales people aren't that great
Well, the idea of using carbon nanotubes as transistors uses a completely different transistor model than a mosfet. The conductance of CNTs come about due to their orientation (imagine a plane of graphite rolled up - there are many ways to make the ends meet, akin to the steepness of a circular staircase). A few orientations are conducting, the rest are insulating.
Semiconducting CNTs occur when you put a twist on the CNT - i don't know the mechanism for that nor the theory behind it, but it is unrelated to the traditional transistor.
SOI is silicon on insulator, which is just an advanced technique used in transistor design - not necessary for the fundamentals of mosfets.
what you're talking about is actually called sputtering, in that high energy particles are used to remove surface attoms. it is not the commonly used definition, but nevertheless, it is the correct definition for sputtering. you're more likely to hear of sputtering as a surface deposition process.
etching for silicon is more likely to done with a chemical etch (pirhanna sol'n, HF, etc.) than a physical one.
There is an industry with much higher rate of advancement. Since the introduction of disposable diapers, their ability to absorb effectively has outpaced the shrinkage rate for effective processors. Thats one of the little 'facts' we bring up in our intro to engineering classes in materials engineering. Weird, but true.
Well, as anybody can tell you, it is not the size or weight of the device, but the density that really matters. The nomad totally blows away the ipod with its lower density. Just so that I can be more 'leet with my ipod, I make sure to put it in a syrofoam packed box to bring that old 'rho down.
the last two upgrades were major - and now the foundation is laid, so likely from now on programs will not be OS version dependent. that problem is no longer a problem.
every machine i've ordered has been up to date w/ software (as in recent as of a month or so before shipping) which is fine by me. if they had to keep things up to the second, that would mean constantly rolling new installation scripts, which is simply not economical, and likely to break at some point. if you got one 9 mo out of date, thats an anomaly, or perhaps punishment for being in a cool place like ireland or the result of some localization issue.
old macs still boot os 9. use one of those if you really want to use an old program. don't bitch if the new computers aren't bloated enough for your tastes.
the cinema displays CAN turn off those pixels, andyour programs won't get stretched, play with it and i'm sure you can figure it out.
the data cd authoring software is so damn simple to use, what is there to complain about? you want bloat? why? it does everything you could need for what a normal user would be doing... if you need to do more, thats when you stop using consumer products!
i don't know what you're talking about with the recent items list, as my apple menu lists them as i tell it to. for rarely used apps, how hard is it to go to the applications menu? if they're so rarely used, whats the problem. if they're more commonly used, keep them in the dock or increase the recent items limits.
there are quartz ports of openoffice, just not by apple. just because its your OS project of choice doesn't mean they can waste the resources on it when they have their own in house office application that ISN'T a port.
Apple does not suck, YOU SUCK, plain and simple. It goes like this. You can pay less than 1000 for an ibook with a small screen but works just fine, or 3000 for a powerbook with a hugeass screen, bigger than your girlfriends ass. They come with lots of software, and you can download all the free shit you want!! The government should pay for it? WTF!!!
Man you have me so pissed at your ignorance and obvious trolling and flamebaiting that i'm not going to read the rest of your post, i'll probably have a coronary.
Well, I am getting a PhD, but not because I want a title.
Anyway, you ignored the send part of my statment - you must pass the exams - in the field of engineering those are the FE(EIT) and PE exams which have extremely low pass rates overall.
And when you have the title PE (prof. engineer) you can sign a document with the full weight and respect of the profession. Same as how a notary public's signature means more. This system of rigorous examination and accountability prevents such things - the tacoma narrows bridge was designed at the turn of the century before such professional societies were widely used. The pinto story is a mis-truth blown to extreme proportion by the media and ignoramii, and ultimately turned to urban legend, similar to the pontiac fiero, apple powerbook burning, cracking in apple cubes (those two examples being ones I've studied), and so on.
I can walk down the street and call my foot a pickle sandwich, but it only matters that I do such a thing if someone believes me and trusts me. You lose the trust and it doesn't matter what I say my foot is.
Same with being an accredited engineer - it becomes possible for there to be professional integrity and accountability, based in the ethics of the situation.
frankly i don't think i could have figured it out this time myself. weird weird weird happening. its brad at san dot arrr arrr dot com (arrrs being the pirate version of r for roadrunner.)
i didn't know the spam obfuscation would look like that when I put the sig on my posts.
I am an engineer in the traditional sense of the word. I find it abhorant that a tech support person puts the word in their title or that there are actual cases of 'sanitation engineers'. To be a legal engineer, you must have the degree, and pass the exams proving that you are capable in your field. Furthermore, you cannot claim to be capable in a related but different engineering field unless you truely are. I may be shiznit in the field of transportation engineering, a subset of civil, but can and would never put my name on anything to do with structures, because I might not have the expertise.
However in the world of IT and programming, any slackjawed yokel who can hack out 5 lines of perl can say they're a badass programmer. No engineering to that. Thats like a poseur mechanical engineer making a basic drawing and saying he 'engineered it'.
There are real software engineers - they do engineer their products, but the trend towards dilution of the term engineer seems to stem mostly from the IT field where a programmer thinks the term synonymous with engineer.

good luck though.

sorry to bitch and moan, but it bothered me..
well, its called jury of your peers for a reason. those are for civil and criminal charges against people...
although a grand jury might be involved, but selection for that comes through different channels than normal jury selection processes.

Yes, post your letters to apple on slashdot stories. This is certainly where they come to check up on public opinion.
no shit, there is something called the sublime, and not the band. look it up.
