The 1 million to one ratio has been beat by OLED screens that have an infinite Contrast ratio. But what folks need to know is there are are in fact 2 contrast ratios. Essentially you can call it dark and light room contrast. For Dark room, it's simple, maximum brightness/maximum darkness as measured in a photonics unit. . Usually you do it over 9 points on the screen and mix min brightness and min darkness for an average. When you look at manufacture's ads, this is the number you see. An LCD can be between 100 and 1000 in this number. The lost is because of LCD leakage, where the black isn't quite black and lets a small percent of light out.
Now the real number is the light room. And Nothing is that good in Light Room. If you shine a light on an screen, you will get a fair amount back. Most LCD screens drop a factor of 10 or more in CR. Very good LCDs have an effective CR of 10-100. It's easy enough to tell the difference between white and black even with a CR of around 2. But you can tell the difference between a CR of 2, 10 and 100 even untrained. So what happens is PR hacks put out the million number, which is even more meaningless as the common methodology has the instruments not able to detect beyond the 10,000 mark. The real number is always worse...
Author's note: I'm a Grad student at a public university. I attended undergrad at another undergrad, and have a bastard science/engineering degree. I've TAed as a undergrad, as well as tutored and graded.
Essentially public schools don't have the money to expand the staff the way they should. In order to attract research money, they need top tier profs.
Profs are tiered when they get their PhD depending on their school's tier. General rule is you are good enough to teach only your tier or below. Thus if I'm a Cal Tech PhD in physics, I can teach anywhere I please. But if I come from Mississippi State I can teach at state schools or community colleges, or small non-prestigious liberal arts schools. The skills required to make it in a PhD program are about scholarship and research. If you are a Caltech grad, you are damn sure a good academic and researcher. However, that doesn't make crap about teaching. The guy from M state might be fantastic instructor, and far better. But unless the school is directly looking for a great instructor they won't consider the M-State guy. Even if they want some one specifically for teaching, they will try and do a tier cutoff often enough.
If you go to a state university, look at your department's staffing. You'll find a great deal of folks who've gone to much better schools than yours. I know one department I was associated with had most of the profs from Harvard and Berkeley. One went to my school. I asked one prof how he ended up at my school, about 3000 miles from his top tier school He said it was simply that every single top tier school spot was taken by other top tier candidates.
Grad student's teach for a few reasons. It's cheaper to pay a grad student 16k/year and waive tuition to have them teach than hire a person with a masters or higher to teach those classes. Most departments have strict budgets, especially if it's a state school. They can't hire as much as they want, or need. They need to get the bodies some how, so they let grads teach. There have been attempts to change the rules and the budgets, but states are generally pulling money out from state schools.
I'm one of 2 grad students in my year not teaching. That's cause some states have rules about giving them to non-residents and can only offer so many. Next year I'll be a resident and will be teaching. TAs are often told, don't worry about doing a good job. We'd rather have you as a shitty TA than a shitty Grad Student. Teaching is secondary at research schools. I've met TAs who've just gotten in from Gambia, India, Pakistan, China, and are working on their English. They take it to heart, and do what they can teaching for the first time.
An even smaller percentage will argue about which of those additional phases really counts. And do magnetic phases count? Is superfluid under fluid or is it a separate phase?
Some folks may say those additional ones are hard to make in labs. Not true anymore for all of them. Anyone who sees plasma tvs or welders sees plasma. Also anyone who stares at Sun sees plasma (as well as blood plasma too).
Condensates are becoming much much more common in physics work in the last few years as its a way to do a lot of fancy quantum work without a billion dollar particle accelerator.
Superfluids can be summed up by saying helium at 3k. No viscosity, very weird. Will flow outta any container thats not sealed.
I've some experience in the AMCLD business and gotta say this ideas been around for a while and has several issues. Depending on the display it's more likely to increase aging effects of the back light, making your monitor die that much faster.
Secondly, the image loses color definition due to the backlight's frequency not necessarily producing the same amount of light pure color. Some times red may be better, some times green. If it gets really bad the a color can be completely skiped. Depends on the addressing method of course.
Thirdly if the addressing method prevents the color definition from being an issue as multiple colors are being addressed at once lines may appear over time, or the screen may noticeably flash.
Lastly there is some attempt to increase the power of white while flashing. This can effect the chromaticity of the white (read colors making it up) and make it biased toward yellow (usually). The brightness can also bleed through the black and make the over all contrast ratio suffer.
Now if they got it to work properly, good for them. I'd just rather not get the first model with this tech if I were you.
Yep, Gotta sort through the crap. "Free" game licenses won't happen, but I can see some sort of dealing forming allowing developers in that hit certain benchmarks.
More or less a free unregulated game market put up by them will be full of alot of crap, some with legal issues because it's such a clear ripoff. It will end up like the 10001 game machines you can buy at flea markets. 1000 versions of the same 10 games, all of them low quality ripoffs.
What they might do is form a way to offer quality indie developers a publisher. This could extend into GBA and DS games.
Hanford Nuclear, where uranium becomes weapons grade plutonium, is not too far from The Dalles either.
So when the earthquake comes, it will 1. Cause the dams to brake, which will create a flood, which will let free the nuclear materials and the gas. Of course, The Dalles is upwind.
Chicago and Idaho and such are downwind....
Not to say that some of sentencing has gone over board, like how screwed up drug and copyright laws are, but longer is better for many career criminals. Look at Britain, it's gone in the soup in recent years because the teeth have been pulled from the police and prison system, crime is rampant, and the hot burglary rate is astounding. The political fixes have all been about social training for criminals, or fixing the root causes. At the same time New York City went draconian and had a huge decrease in crime.
Now sending some one to prison for five years for stealing a mailbox is stupid, if they did it because they were trying to steal check and/or do Identity theft, it isn't. More leeway towards judges is one answer (besides changing drug laws of course).
As for video games and cable TV, it should be used a privilege to dangle in front of prisoners, a positive reinforcement beyond the negative (which don't work well for lifers). Frankly, if it can be used efficiently, and used to better the system, this should be a matter for Bureau of Prisons and not the state senate.
Those folks sold to 3M who now own all rights to the Billion Dollar a year Dbef (directional brightness enhancing film) market. Dbefs are films that allow some light that was polarized one way to change polarization, while keeping the other axis unchanged, can nearly double backlight brightness and dramatically improves image quality. The honeywell case really infringes on the OSI/3M patents and I know screwing with 3M is bad bad news. They might not be selling Dbef, but they are trying to get a royalty out of 3M customers for buying 3M products and using them. I might be misstating facts, But I know someone will come and bash me for it.
IF you like orange instead of red. The colors were just not right. Close, but wrong enough on red that a full red screen always looked orange on the screen. Still have hopes, but Kodak isn't ready yet.
You dont need polarizers and color filters (those absorb >2/3 of the light in a lcd)
Actually the different layers of an AMLCD tend to absorb 90+% of the light before it gets about. You lose 60% thru the polarizers unless using DBEF, and then around a third of the 40% by going thru color filters, then there are AR coatings and what ever other coatings the company added to improve performance over angles. LCDs still beat CRT in pure power efficenticy.
OLEDs don't need the backlight, nor an electron gun, just current to each cell, like a plasma display or an EL display. However OLEDs have their own issues in lifetime. LCD backlights can last a very long time. Now that some are getting LED backlights, were talking 100K+ hours. CRTs are good for damn long times too. With those two it's hard to find a good unit with life times less than 25,000 hours.
Most OLEDs tend to die in a thousand. I would hope Sony has licked that problem. It makes me wonder when they leave it off that page.
One other thing to add about the article is the contrast ratio, if measured in a dark room, is effectively meaningless. The real world contrast ratio needs to take haze, specular, and diffuse reflections into account. Usually handhelds have a real world CR of 10 rather than the claimed 100. An OLED is usually much more shiny than transflective displays. The OLED still has a much better CR than an equivelent LCD, but it isn't the factor 10 improvement they are claiming in real world conditions.
Not all. I had a physics prof who was married to a math prof. They both have their own research areas that scare the heck outta me with the math, but know how to tone it down to undergrads. My undergraduate courses got overhauled and replaced by a new pilot program that breaks the work up into problem types. This makes mathmatical physics much easier to deal with then subject area. Rather than skipping to the hardest parts 'cause you gotta finish mechanics before em' you go in a much more sensible manor. We had an entire course on wave motion, going from a string to a spring to em waves in coax to hydrogen atoms. It makes is much easier to understand when you can always point back a few steps with a clear every day example.
Hmm, don't think there is that much office space near Ellington field. Mostly restricted government areas that you get shot at by National Guardsmen for taking photos of. The KC-135 is done anyway. Too old and time for a very expensive C check, so it is now time for a DC-9 to do the Job. The folks at Ellington are much happier, even if it is smaller than the 707, it has better engines and has much more ease of control.
I was on a SOAR team, where Nasa allows university students to fly experiments on the KC-135. There is much research done on them, but much of it is sidelined to PR. The PR folks make most the decisions on the plane. They know lack of safety is not only bad for them and the plane, but for budget and PR. When FOD can kill an $80K+ engine, they make damn sure there are few chances for it to do so. That's why you can't bring your own tools anywhere on Elington field (same place W was "based" in Texas Air National Guard).
When I went nearly half the experimenters got quite sick. The smart groups made the experiments automated and spend the time doing flying kicks and walking up walls. Or, of course, Vomiting. Nasa hates the name Vomit Comet, but everyone calls it that. A problem was the camera people would come up to you on the plane while you were frantically working to make your project work due to some bug you missed before hand. When they come you are suppose to smile and wave and say hi to folks at home that will get shown the video. This is rather bad for a serious project that has 10k+ invested in it for plane tickets and hotel rooms.
I'm unsure if this is good or bad. Good for society that there is more research, bad for other first world nations because China will be a major player in the information economy.
Of course I could RTFA and find out what they want me to feel. But this is Slashdot after all.

Jeopardy tapes five eps a week. This would be about six weeks worth of episodes before he bites it. Considering the Tourny coming up soon, which is another 3 weeks, this could be true, but means the leak happened real quick after the actual fact.
I bought New copies of Chrono Trigger and Chrono Cross with in the last few months. Chrono Trigger has a PSX re-release with Final Fantasy 4. Chrono Cross was greatest hits and can be bought in the same places you can get a copy of Tactics or FF7.
Wow you send an Email to a corperation aim and it doesnt' get a timely reply?
Duh. Happens all the time (Sadly). When it is a big issue like this you need to make more serious efforts and send written letters to multiple departments and aimed at specific individuals. Otherwise you get lost in the email filter most companies tend to have. I suspect Square-Enix gets a few hundred random emails a day, many junk from leet fans and non-fans. That's inpart while no one payed attention. Email can be used for only so much. You need to follow up with other means to get taken seriously.
Anyway, i can understand why they file such patents. If they don't, they get exposed to another company filing them later. Though they suck, the IP laws exist, and a business has no other choice than to play according to those rules...
If they don't and some group of jerks tries to leverage similar patents on the online consoles, say like a future SCO, then what Big N can do is break out the patents to defend themselves. I suspect these are more of a cover-all-bases sort of thing. I doubt they will ever enforce it, or try to get Big M to pay royalties, both N and M have been sued enough to know how badly it can go. Remember Apple's look and feel lawsuit? Or MGM suing for Donkey Kong? Or the massive Anti-Trust suits that prove to increase profits from the 'harsh settlements'. These had their impacts on Nintendo and Microsoft such that they don't sue frivously.
The ratings are not law. If I am 14 and try to buy GTA, I don't get in legal trouble. Nor does a clerk who sells to me. His company may have actions against the clerk as a matter of corporate policy, much like some movie chains.
