Re-read that again. Although the listeners didn't hear the extra frequencies by themselves, they basically rated the reproduced sound higher when those frequencies were included.
The conlcusions I read in another paper were that the ear isn't the only receptor of sonic energy. Did you read the article a few months back regarding how extremely low frequencies (inaudible) produced a sense of paranoia and was pointed at as a possible explanation for people experiencing paranormal phenomena? It's the same sort of deal. We can't hear those higher frequencies, but we 'sense' them, most likely through the skin or some other as-yet-unknown process.
Maybe for older folks whose hearing has degraded somewhat. People usually cite an upper limit of around 20kHz. I can certainly hear a tone at 20kHz, from a good tone generator (not a cheap one with harmonic interference.) That alone puts the Nyquist rate at 40kHz.
What's more, although people may not consciously perceive higher frequencies, work has shown that people do subconsciously perceive them.
To quote (from the article I'm linking):
Oohashi and his colleagues recorded gamelan to a bandwidth of 60 kHz, and played back the recording to listeners through a speaker system with an extra tweeter for the range above 26 kHz. This tweeter was driven by its own amplifier, and the 26 kHz electronic crossover before the amplifier used steep filters. The experimenters found that the listeners' EEGs and their subjective ratings of the sound quality were affected by whether this "ultra-tweeter" was on or off, even though the listeners explicitly denied that the reproduced sound was affected by the ultra-tweeter, and also denied, when presented with the ultrasonics alone, that any sound at all was being played.
The author also notes such facts as that 40% of a set of cymbal's audio energy is above 20kHz. So a 96kHz audio recording (range=48kHz) is not unreasonable. But good luck finding equipment to really play it back on correctly:-)
Just thought I should add, not all TV is as attrocious as reality TV. I love Stargate SG-1, for example. I just don't like to watch it on Sci-Fi and have 5 minute interruptions every 10 minutes. (Well, wouldn't if I subscribed to cable/satellite.) I download all the newer episodes and own several seasons on DVD.
Which actually brings me to another point. I know a lot of people who spend an extra $15 dollars a much just to watch, say, the Sorpranos. Now, If you didn't subscribe to HBO, you could use the same money to buy and own those episodes on DVD. Oh well.
For movies, I go to the theater or rent/buy a DVD. The latter allow me to watch when I want and even pause if I need a break for an incoming phone call or to go to the toilet or refrigerator.
And the cinema/DVDs are (ostensibly) commercial free. Hurray! Although, in the last year or so, I've gone to a couple of theaters I don't normally go to and have seen a crapload of commercials aired before the movie. @#&*%@#
Commercials are the reason I gave up TV. I despise advertising. If I want information on a new product, I'll go out and look for it. And that was about 6 years ago...from what I've seen, the situation has only gotten worse. Not to mention the plague that is reality TV. Remainds me of how the Romans got their kicks, shortly before their empire collapsed.
Occasionally, I still turn on PBS or, if I'm at my parents' (who have DirecTV), I'll watch Turner Classic Movies, etc. Commercial free.
As an aside, I did a marketing survey for a friend's girlfriend, who was in college studying marketing [God-have-mercy-on-her-soul.] She told me that the result was that traditional advertising had about a 6% effectiveness on me, by the test's rating system. I'm an advertiser's worst nightmare:-)
As many others have said, I find grouping annoying as hell. Kinda like the default XP theme. *shudder* I'm not looking forward to how cute they try to make Longhorn. (Well, if it has integrated DRM, I won't touch it with a ten foot stick anyway.)
But I digress... Several years back, I doubled-up my taskbar (so there are two rows at the bottom) and find that much more useful when I have many windows open.
Not too long after 9/11, I was surfing the net and needed to look up something at the Library of Congress for one of my classes. It wouldn't connect. At first I thought we'd just lost DNS (not so uncommon an occurance at my university in those days), but found I could still connect to slashdot.org and some other sites.
Being a geek, I thought up a list of about 30 sites to ping, scattered across the US. (.govs and.edus mostly.) The ones that replied, I plotted on a US map based on their DNS LOC. (A project I wrote for a previous class.)
I freaked out a bit when the mid-atlantic seaboard came up missing. I crossed my fingers hoping that it was just some idiot who'd accidently cut one of the main fibers (which it what it ended up being) and not that Washington DC was now a big hole in the ground.
Amen. I spent the last year in a city while I was working on my master's degree and I hated it. It simply amazes me that people want to live in cities.
Don't get me wrong, I enjoy the culture. Museums, music, theatre, good restaurants, etc. I just could not possibly conceive of dealing with the trade-offs long term. Traffic. Noise. Light pollution. Higher cost of living. PEOPLE. Ugh.
The first thing I did when I moved into my apartment was to put up a double-thick curtain across the window in my bedroom. To hell with my rental agreement. It blocked 99% of the damn light from coming in. For airflow and to help drown out external sound, I kept a stand fan going all of the time. It's actually pretty hypnotic sometimes, which helps.
It really hit me how much I disliked it when I looked up at the sky one night and could only make out a handful of stars...
Oh, give me land, lots of land under starry skies above Don't fence me in Let me ride through the wide open country that I love Don't fence me in Let me be by myself in the evenin' breeze And listen to the murmur of the cottonwood trees Send me off forever but I ask you please Don't fence me in
Well, I'm a recent (May '03) computer engineering graduate. We programmed in assembly on MIPs, x86, Motorola, and several other architectures that aren't coming to mind at the moment.
The CompE curriculum at my university was very electronics / hardware oriented, so there was quite a bit of asm to learn. Not to mention VHDL, etc, which is also quite valuable stuff to know. Nothing like building individual logic from scratch and putting it together to simulate a microprocessor. Then trying to implement it on a chip.
So, Cadillac: KE = (0.5)(4000)(50)^2 = 5000000 units Mini: KE = (0.5)(2000)(100)^2 = 10000000 units
So the mini would have to travel ~71 mph to have the same energy. I'm not working out the units 'cause I hate the imperial system for this sort of thing. And yes, I'm an American. I'm also an engineer.
I too wouldn't mind being able to clone the old window in the new window; it's one thing about IE I grew to like. I did it so I could have the same history in both windows. For my browsing habits, at least, it is nice to jump around in both.
Hasn't the Bush administration's terror-chiller theatre been scaring you with that scenario for the last 3 years?
Not particularly. "Dirty Bombs" aren't really all that dangerous (in the grand scheme of things.) It is mostly a psychologcal weapon.
Thankfully, there are two main problems/tradeoffs:
1) If you grind the dangerous isotope(s) down into dust so you have a high dispersion rate (cover a larger area), you drastically reduce the dose that any one person will receive.
2) If you leave the isotope(s) in the form you stole them in (ie, spent fuel rods, etc.), then you scatter around a few big chunks which don't kill all that many people and can be recovered fairly easily.
Good luck trying to calm down a hysterical general public though. "Oh dear god, it is radioactive!!!!"
Haha. Northeast Ohio weather gets a little old after a while, for sure. As a lifelong Geauga county resident (snowbelt), I can't remember how many times I've heard Dick Goddard say, "We can expect a trace to 3 inches of snow here in Cleveland, 4 inches to 2 feet in the snowbelt"
Avegrage yearly snowfall is around 110" (2.8m), and we picked up 226" (5.4m) locally in 1996. For those of you reading this from Europe thinking, "Ha, we get three times as much here in the Alps!", realize that a) NE Ohio isn't mountainous and b) we're only located about 40 degrees north latitude.
Lake-effect snow makes life very interesting. Ask anyone from here, along I-90, and up through eastern New York state.:-)
I spent the last winter in Raleigh, North Carolina, and loved watching the whole city shut down when they got a couple of inches. I could live with another winter like that...
I've been following OLED's progress for years and I'm glad they're finally getting somewhat competitive. It's a cool technology.
For a television, however, there's another really cool technology I'm waiting for to become commercially available (to the consumer: Grating Light Valve based projection TVs.
Red, Green, and Blue diode lasers (RGB) + a Microelectromechanical (MEM) diffraction ribbon = very bright, detailed, lifelike image. I've heard anecdotally about people who became disoriented because the image looked 'too lifelike.'
My personal beef with solar power is that, where I live, we statisticly receive around 150 days of sun a year, disproportionally in the warmer months. We've gone 30 days with grey, overcast skies in the winter. And no, I'm not from Alaska.
Wind and tides are out. Solar isn't a particularly good choice here except as a secondary source. (But it could possibly be used to separate and store hydrogen and oxygen. Don't know what the efficiencies are.) So we're back to "traditional" sources like natural gas and nuclear.
And that's how it should be really, one size doesn't fit all. Let the places like Arizona (with >300 days of solar a year) do solar power. Kudos. I say we up here build some small Gen IV nuclear plants (which can also generate hydrogen) and suppliment with renewables where we can. Flywheels make sense for industry (even homes sometimes) to store excess energy. Systems with magnetic bearing have crossed the 90% efficiency threshold. No hazardous materials and high maintenance costs as with batteries. Let's also put more money into fuel reprocessing and go for a closed nuclear fuel cycle to reduce waste.
The big problem in the US regarding nuclear innovation is, IMHO, that the power companies are all privately owned. They won't risk the capital to do anything innovative. That and so many environmental groups spread disinformation about the technologies that Joe Average gets freaked out by the word nuclear. Nuclear is the only way I see us ever making the bridge to a hydrogen economy...every other means of hydrogen production is far too inefficient, dirty, or wasteful.
Fusion...hmmmmm. Experiments have reached break-even and have even produced excess power. It is basically now a scaling problem, with some materials and containment problems tossed into the mess. If they ever stop vacillating on ITER and actually start construction on the damn thing, it will be easily be 10 years before it goes online, with about 20 years of experiments and tweaking planned. Then if it all worked they can begin with commercial plants. If anyone will pay for them.
Here's an explanation (read - Public Relations Piece) of IETR for the less-technical.
I've heard that some Germans get a big kick out of hearing the Amish here in Ohio/Pennsylvania speak. Being a closed, somewhat isolated community, the language has basically stagnated for the last few hundred years. (The other groups of "Pennsylvania Deutsch" speakers have mostly died out or adopted English.)
An example I found, Excert from Lord's Prayer, Amish dialect:
Unser Fadder im Himmel, dei Naame loss heilich sei, Dei Reich loss kumme, Dei Wille loss gedu sei, uff die Erd wie im Himmel
Contrast with modern German
Vater unser im Himmel, geheiligt werde dein Name. dein Reich komme, dein Wille geschehe wie im Himmel, so auf Erden.
You're both wrong. According to the ancient Bovispuerus Nealus Prophesies, at that point, the only way to save the entire universe is for some poor fool to inadvertantly post the story as a dupe before we all imlpode into nothingness. Unfortunately, the writings are vague on just who this person will be, just that he will be a great warrior of the 'laxus aranea mundi', wherever that is...
What are you talking about? The United States Congress officially adopted the metric system in 1866.:-) They just didn't force people to stop using the units and measures with which they were familiar.
Coming from a science/engineering background, I *hate* working in traditional/avoirdupois/empire units.
On the other hand, it feels unnatural to talk about the weather in anything but degrees Fahrenheit. I've tried. I have plenty of European relatives. But centigrade's units feel too "big" and awkward.
The Doomsday Clock, probably the major herald of nuclear danger, was set between 3 and 6 minutes 'till midnight for most of the 80s. It was judiciously set back as far as 17 minutes 'till midnight in the 90s. And now, with recent world events, the clock was again set to 7 minutes 'till midnight on Feb 27, 2002.
Well, yeah, that's all understandable. And your home might not be able to self-sustain. Think about it this way though.
You don't have gasoline as a natural resource out there, do you?
No, no one does. It needs to be refined and processed somewhere then piped or carried by truck/train to stations. But, unless you're really out in the hinterlands, you don't think, "Oh no, the nearest gas station is 3 states away."
The aim is that, hopefully, hydrogen will become as ubiquitous as gasoline. Gasoline generators will be replaced by hydrogen-electric and whatnot. And if you've currently got a natural gas well on your property or soemthing, well, why not just keep on using it? As you say, not everyone will be able to produce their own, much like not everyone can refine their own crude or can have a waterfall and turbine on their property.
Hydrogen will (hopefully) greatly reduce pollution, etc. It will never eliminate it. And frankly, it's a piss-poor world that had to rely on only one option for power.

Refresher:
Kinetic energy, KE = (0.5)(M)(v^2)
So,
Cadillac: KE = (0.5)(4000)(50)^2 = 5000000 units
