yeah, I will let him take the first line of defense. Maybe if I am lucky the pirates only have a couple hundred rounds of ammo each.
I have heard of pirates taking cargo ships, which may have a crew of only a couple dozen, but not a cruise ship. Mind you, I don't really keep up on pirate activity though.
At atmospheric pressure, carbon dioxide does indeed go from a liquid to a solid. At elevated pressure though it will form a liquid. Compressed carbon dioxide cylinders, such as those found in a lab, etc., actually contain mostly liquid carbon dioxide and hold a constant pressure (I think about 700psi) while being used until all the liquid carbon dioxide evaporates and the remaining gas decompresses.
But what if all that co2 gets into the water.... Would that kill any animal life in the water. Fish breath the oxygen in the water but if the water had a high co2 level, could they survive?
At the concentrations typically found in seawater, the concentration of oxygen and carbon dioxide are independent of each other. A very high concentration of carbon dioxide could reduce the solubility of oxygen in the water, but at that point the drastically reduced pH would likely have caused other problems.
So why not stick to tried and true near-shore and land based wind turbines?
Because the rich beachfront property owners (yeah, yeah, yeah I know they are not all rich) don't want the former ruining their view of the water and the latter usually irk enough of the landlocked masses that they even have enough clout to keep them away.
By the way, don't assume that just because something has not been done before that there must be some good reason. Sometimes the reason that an idea has not been tried before is that people are lazy, uncreative, or afraid that there must be some good reason that it has not been tried before.
Some people will overlook minor problems in an attempt to rationalize why they payed so much for an inferior product. Someone who has paid for a movie or music may try to convinve themselves that they enjoyed it rather than admit that they wasted their money.
I think that someones willingness to complain may also have to do with their overall happiness with the product and if they feel they got their money's worth. If you liked a movie or car for the most part, you may be less likely to complain about the weak special effects or the intermittent squeak in the rear whether you paid for it or not. However if a product is a dog, the consumer will likely complain about every little thing.
Could the same not be said about any emerging technology? I bet it took things like television, cars, and telephones a few years to gain traction in the American household, but thereafter became an integral part of our lifestyle. I don't see why anyone would think the Internet would be any different.
Not necessarily. There are plenty of "mature" technologies that are not a part of the average household (own any small planes?). Whether a technology gains widespread adoption depends on the cost and appeal to consumers. The internet could have easily remained just a geeky way of exchanging research information if it had not been adopted for commercial use.
From TFA, the information released was actually from data collected in 2003, so the interval was more like six years. The information is likely of even less "use" since things have probably changed a bit even since then.
Not sure the information is all that useful to the public in general anyway other than as an interesting tidbit. If XYZ company wants to get useful data to develop an online strategy they can pay for their own study.
What are you talking about? I'm sure I will have next October 26 off to celebrate Overclocked Radeon Broke 1GHz Barrier Day. Heck, this may even become Overclocked GPU Awareness Week.
While this is true, I think just about any technology to get the image data to the monitor relies on some sort of "frame rate". You aren't going to notice any difference between a 16ms LCD and a 3ms LCD if you are playing some FPS and getting only 30 frames per second out of your graphics card because the pixels won't need to change more than once every 33ms.
Does anyone know what the expected failure mode of the rovers was supposed to be after three months?
Perhaps they were not so much "over-engineered" as much as conditions just weren't as harsh as were expected. There is a subtle difference. Like say the Martian dust was not quite as plentiful, sticky, or abrasive as engineers were led to believe. That certain items would be built more robust than necessary in this case is due to poor specifications rather than overzealous engineering.
Or perhaps NASA isn't telling us about the helpful Martians who have been changing the oil every three months.
Does the shopping mall have any right, legally, morally, or ethically, to restrict what you do in your back yard?
Of course not. Nor do I have the right to demand entrance to the mall if it chooses to deny me for whatever reason (provided it's not based on my sex, race, religion, hair color, "sign", blah, blah, blah).
Would you expect a school to be able to enforce a dress code off-campus? Any student seen in Starbucks on the weekend gets suspended? Any student seen browsing the banned book display at the bookstore gets called into the principal's office?
No, but since it is a private school I could pull my children from such a school if I found its policies overzealous. The school has no power over me like a government or, to a lesser extent, employer does, so it is pretty easy to avoid their rules.
That's not how it works. The box would be worth about $50 if you could buy one. But instead, you have to rent one from the cable company for $7.95 a month indefinently.
There is no reason that you would have to have a converter. The cable company could just convert it to analog and transmit it over their lines in that format, much like the "standard" service that most offer now. There really isn't any reason why the cable companies would have to transmit in digital just because that is how it is broadcast.
On the other hand, this will be a good excuse to push people to their digital services. "Sorry, we are going all-digital now. That will be another $20 a month please."
I am not really involved in the PM research, but I would guess that the differing contaminants and burn conditions will lead to different composition and size distribution of the particulates in the soot. For example, diesel soot will likely have higher concentrations of sulfur containing compounds than what you would get from wood. Soot from coal combustion might contain mercury and other heavy metals. I think the combustion of the gaseous/aerosolized diesel also leads to finer soot production than say the combustion of wood logs in a fireplace.
Diesel nanoparticles?? You mean as in common contaminants, or the longchain carbon molecules themselves? And what about fuel-oil home heating furnaces that use #2 diesel??
I guess that wasn't clear. Fine and ultra-fine soot particles from diesel combustion are what is being studied.
There's scant concern about those - diesel engines continue to operate unabated worldwide.
I work for the EPA and happen to know a couple people looking into the health effects (in mice) of fine particulates and are just starting a new project to look at diesel particles. My fellow postdoc friend has been smelling like diesel a lot lately. The odor is really quite a nice accompanyment to lunch:)
The problem with abating diesel particulate pollution is that a lot of people will likely bitch loudly about the cost of prevention or switching to a less polluting technology. It is a lot easier to study the potential effects of a new technology before it gains widespread adoption rather than trying to put the genie back in the bottle.
A third degree of prescision (jerk), might be useful for NASA, but is of no interest to the public. Additionally acceleration is something that most people reading about the ISS will understand, unlike jerk, which is rarely a useful parameter.
While most people might understand the concept of acceleration, most won't be able to write and solve the quadratic equation needed to estimate the time at which the ISS "lands". More likely it would burn up in the atmosphere at some lower altitude though which further muddies the issue. The most useful and interesting information for the general public would be to just give an estimate of when it becomes too late to do anything.
As you say, you would need a mechanism for aiming - I was imagining sights on the pole attached to the mirror that they could use to line up with a specific spot on the ship, and another to line up with the sun - it shouldn't be too difficult to come up with a simple mechanism that the troops could be trained to use.
I learned in boyscouts a very simple way to aim the reflection of the sun from a mirror at a distant object. You need a mirror that is reflective on both sides with a hole in it. Look through the hole at the target. There should be a spot of sunlight on the ground or your body from the sun shining through the hole in the mirror. Angle the mirror such that the reflection in the back of the mirror of this spot of light lines up with hole in the mirror. The suns rays will now be directed at the target. Many outdoor provisions companies sell small mirrors of this type for signalling purposes in emergencies.
1) Kill OpenOffice, which if left to thrive over on linux will eventually also eat into their windows market (they are obviously worried about this - see earlier articles involving the state of Massachusettes).
But for non-geeks the biggest motivator for going to Linux/OpenOffice has got to be cost. On an OEM machine, the cost of the OS is secondary to the cost of getting an Office license. I think in an earlier article about OS-free systems from Dell it was pointed out that the OS-free systems were only $30 less than a comparable system with Windows.
So google puts in the work in scanning, indexing, and hosting the books, and the authors, who have done no aditional work deserve to be paid a cut? Surely it should be the other way round, google puts in the work, auther sells more books and gives cut to google for the advertising?
Without the books, there would be no Google Print. Without Google Print, authors have been and will continue to sell books. Sounds like Google needs the authors more than the authors need the "advertising" that they never asked for.
BUT in order to qualify for the PRIVILEGE of BELL SOUTH DSL we have to have the 40$ phone service.
Really? I have DSL through a local ISP and the cheapest BS local service ($15+~$8 "fees") with no problems. Never saw anything on the BS website that said you need to have anything more than the basic service. It's not cheap but its cheaper.

South Koreans buying it from neighboring countries would be a win-win for MS; they get the South Korean sales, but none of the pesky regulation.

Maybe mentioning Google trumps the need for ominous speculation.
Yeah,right.....for gaming.
