High school physics isn't the be all and end all of physics.
Weight refers to measure of the force of gravity on a mass. Mass is independent of gravity.
Really? So when you are weighed in a doctor's office, what sort of scale do they use? Unless it's a digital one, it's probably a triple-beam balance. Put that thing on the moon, and it'll tell you the same weight as it does on earth. In most common use, "weight" refers to "mass", not force due to gravity. The fact that provided you stick to the surface of the Earth mass and force due to gravity are directly proportional just muddies the issue.
BTW, if weight is the force of gravity on a mass: If you're in low orbit around the earth, how much do you weigh? A balance scale is useless, as is a pressure-sensitive one. The usual answer is that you're "weightless". But the force of gravity in low orbit is nearly the same as it is on the surface; GMm/R^2 doesn't lie. So this is a meaning of weight different from either "mass" or "force of gravity on a mass".
If you know something you're considering buying potentially directly hurts the workers making them, do you buy it anyway?
Yes. I buy products made on assembly lines with nonzero accident rates, made from metals mined under dangerous conditions (ALL of them are), made from oil drilled and refined under dangerous conditions, processed using energy from coal mined under dangerous conditions, transported over dangerous roads, etc.
Fact is, every product -- even those made entirely in 1st world Western countries -- required some danger somewhere in its manufacturing process. You can fairly claim that Chinese manufacturing is unnecessarily dangerous, but you can't set the bar at zero.
Broadcasting information in the clear leaves it open to everyone. It's really no different than having a radio station and being surprised people tune in, or having a conversation on a crowded elevator and being upset that someone overheard you.
Well, yeah, But then using that information to access someone else's account is another story. If I overhear someone's safe combination, I still don't have the right to open their safe, even if I happen to have legitimate access to the area it's in, and even if I'm just putting in a note telling them they're an idiot.
While a lock on a house is very easy to pick, it serves it's purpose. It keeps honest people honest. Frankly, people who want to get into your house are going to get in quite easily, regardless of your locks. Windows tend to do that.
Honest people are honest whether or not your door is locked. The lock serves to deter the dishonest but lazy, the dishonest but afraid of getting caught, or the merely bored.
Ah, I'm immediately suspicious of any summary that mentions something weighing a kilo, anyway. It's mass, not weight! It's like saying someone masses two hundred pounds...that's weight, not mass! They mass in slugs, which is just amusing as all getout. Metric loses so much of the color the Imperial system has...where else can you measure things in gills, hogsheads, rods, chains, and slugs, anyway?
This is an amusing fairy tale, but measuring mass in pounds is fairly common, and the term "weight" often actually refers to mass. When you weigh something on a balance scale, it is mass you are determining, not force. Scales which are valid for trade are typically either balance type, or measure force but are calibrated against known masses.
There is a system which measures mass in slugs. There is also a system which measures mass in pounds and force in poundals. And the non-SI kg-f (kilogram force) is commonly used as well.
I am a pretty left-leaning guy, and I am no huge fan of Gitmo, but there is probably a reason that Gitmo still hasn't been closed. After all, President Obama would have really fired up his base going into these midterm elections if he could check off "closed Gitmo" on his list of to-dos. Therefore, I really, honestly believe that there are some really scary things happening at Gitmo with very few horrible, hardcore killers who have been giving up all sorts of useful intelligence but who cannot be tried in a civilian court because they have been endlessly tortured to obtain that information. Senator Obama made his campaign promises to close down Gitmo not knowing the secret horrors and President Obama has to backtrack because he now knows about the shit going on.
I do not like the "national security" thing but this might be one of the cases where it actually is happening.
Sucker. That's just what they want you to think.
Besides, if it were really the case, Obama could shut down Gitmo and have the horrible hardcore killers assassinated after their release.
Also you can patent specific implementations and methodologies. It's entirely possible and likely that other email synchronization systems can be employed that don't run afoul of Microsoft's patents.
Doesn't work that way. When the patent office is considering prior art, any trifling differences between the patent and the prior art mean the prior art doesn't make the patent non-novel. However, in practice, when infringement lawsuit time comes around, small differences between the patent and the claimed infringing device do not mean the device is not infringing. Even if the device is closer to the prior art than the patented implementation.
OK, maybe not these overpriced toys. But a rather large number of the chairs I was stuck with in primary and secondary school had a molded and textured plastic seat and back with large metal rivets holding the back and seat to a metal frame. Never mind the ordinary discomfort of such an apparatus. Consider what happens when cloth moves against plastic... you get a static charge. Guess where that discharges? Right through the metal rivets. So in dry weather, sitting in such a chair meant constantly getting shocked in the back, legs, and butt. Real conducive to learning, that.
By contrast, the typical American liberal/progressive favors proactive government involvement in many areas, but firm protection of civil liberties-- which no doubt sounds paradoxical, if not contradictory, to the libertarian.
The paradox is easily resolved; the American liberal has discarded civil liberty in favor of equality in the lack of it. They don't mind random searches provided they're actually random and don't somehow favor white people. Cruel and unusual punishment is fine as long as it applies as well to powdered cocaine users as well as crack users. Stop and identify statutes are find provided they don't target Hispanics.
That's cowardly, lazy justification. Do you really want to screw with some political types? Get a thousand people like yourself to show up and turn in blank ballots.
Even assuming I could do so, the ballots would merely discarded as invalid and noted on a report somewhere.
Why does this company have a penchant for introducing weird engine technology and then abandoning it.
Because they are willing to take risks? Mazda still makes rotary-powered cars; while they aren't fuel efficient they do have a great power-to-weight ratio, and they also screw with some governments' per-cylinder taxes. Mazda is also a pioneer in the use of Miller-cycle engines in cars, which has worked out better (than the Wankel) for them, but apparently costs too much to put into general use.
The good thing about this is that if Mazda says they're going to introduce some wacky new engine technology, there's a much better chance of them actually doing so in a production car than if, e.g., GM says so. The bad side of it is if you buy it, you might end up with an orphan.
Sure. On diesel fuel, which has a higher energy content. And using the diesel cycle, which still produces copious amounts of soot despite what its apologists say.
horse power is a misleading gauge of power, torque is what turns the wheels.
No, torque _at the wheels_ turns the wheels. This number is limited by gearing and engine horsepower.
The students were the ones rioting. They are responsible for their own behavior regardless of the actions of the police.
That's right, just give the cops a free pass. They can do whatever the hell they want, including throwing people in a cage for no good reason, and any reaction will be judged as if it was completely unprovoked.
The United States sponsored the terrorists too. A major reason Osama bin Laden is so skilled at terrorism is that he learned from and was at one point funded by the CIA.
If I teach a man to shoot and we later part ways, and sometime after that he shoots someone to death, am I responsible?
ObGeekAnalogy: Is Obi-wan Kenobi responsible for the destruction of Aldebaaran?
Cable companies are now supplying DVRs, and, like I said, providing free versions of their shows online. I can't think of a format shifting example, but then again, I can't think of anyone who expects to be able to format-shift their TV.
Cable companies aren't the issue. NBC, ABC, and CBS are not cable companies.
What I do want is sustainable practices when it comes to art. I don't mind if we do away with copyright, only if we have a working, implemented, and already used system that replaces all of copyrights functions.
What utter bullshit. Yeah, you don't mind if we do away with copyright as long as we first replace it with something exactly the same.
Let's get this straight. Choosing to search for and illegally download from a torrent is not the same as walking down the street, hearing buskers and seeing billboards. To claim otherwise is utterly dishonest.
The buskers don't think so. They get quite upset at people who listen but don't donate.
If it's on your Facebook status, and you don't have it covered with restrictive privacy settings, you de facto do want the world to know.
But this can happen regardless of your privacy settings. You set your profile to include the fact that you are gay. You make that private, and manage to keep it private no matter how many times they change things. But the fact that it's private doesn't mean advertisers can't target ads based on it. So the advertisers set up an ad which doesn't look like it has anything to do with sexual preference, but is targeted to gay men. Now anyone who responds to that particular ad is known to have a facebook profile they are saying they are gay men.
Of course, the opportunities for abuse are large. The example in the article of a nursing program, for instance : perhaps anyone who applied to the program via THAT ad would be rejected out of hand.
Fact is, though, that if you try to stop a shooter, the chances of you ending up on the victim list is a lot higher than you ending up the hero who stopped him.
Maybe. But if I _don't_ try to stop him, I've got no chance of doing so -- and still a good chance of ending up on the victim list.
Same thing for violence. I used to do martial arts. One of the things you learn is that most black belts get their asses kicked in a streetfight.
I wouldn't suggest trying to engage an attacker in a fair fight of any sort. A blow from behind with a heavy blunt object, for example, is perfectly reasonable.
Again, unless you are trained for this particular kind of events, your "heroism" will very likely make things worse, not better.
Is this actually true, or is it just something repeated ad nauseum by the "authorities"? I mean, the attacker likely isn't trained either.
The exact details are crucial. If the most likely thing to happen if nobody does anything is that the attacker goes on a rampage through an evacuated building until the SWAT teams show up, sure, why not let the guys with the guns and the armor take care of it.
But if no matter what the police response, the attacker is going to be able to kill a bunch more people before they can escape, anyone in a position to credibly try stopping him should at least consider it.
And, dude, seriously?... it's a bicycle, and you want to get on with the old-testament wrath, like branding someone's forehead or hacking off appendages?
You have to admit, the punishments were effective. There are no bicycle thefts recorded in the Old Testament or any contemporaneous document.
But I imagine the riot was the fault of the police, not the students.
Indeed. The students were apparently just partying in the streets when the cops came down and said 'Get in your houses or we'll arrest you', and then made good on their threats. The cops turned a party into a riot.
Gimme a break. These batteries are based on electro-chemistry. You know, interactions between molecules. Everything that goes on in batteries, all batteries, are nanoscale, by definition. Corrosion in the electrodes had been known and studied for ages. It is a damn chemical reaction that will happen at molecular level.
They're not talking about the chemistry, though. They're talking about structural changes. So while the "nano" may be annoying, it's appropriate.
Still, this doesn't sound any different than already well-known mechanisms in lithium and nickel batteries. But being a good Slashdotter I only looked the summary, and that I only skimmed.
I know it says 15 years, but I have a feeling that if China really decided to withhold rare earth minerals for an extended time we'd find a supply a bit faster.
Probably 1 year to open the mine, 2 to get it up to full production... and the other 13 spent doing environmental studies, fighting lawsuits from everyone and their uncle, jumping through regulatory hoops, etc.

Here is one incarnation of said torture device.
Fine, let's define a C virtual machine. It'll probably look roughly like a 64-bit extension of the Motorola 68020.
Even assuming I could do so, the ballots would merely discarded as invalid and noted on a report somewhere.
Same effect.
Euclidean travelling salesman is still NP-complete.

Or maybe Jobs cut a deal with Oracle for them to port to OS X. Though IMO, with Oracle in charge, Java's days may be numbered anyway.
