To a certain extent. Every last perscription has negative effects, some of them are very serious. If they didn't, they'd be called vitimins.
What bothers me is that drug companies are forced to down'lay the negative effects of useful drugs to even be able to use them at all. If there is any hint of a downside, they get sued. Nevermind that their drug gave someone an extra two years to live or made their last ten bearable, if there is any downside at all, they get sued. But it's worse than that. They get sued more often and pay more money when the negative effects are known and announced.
This is rediculous. You shouldn't be able to sue a drug company for known complications of their drug. You should only be able to sue if they neglected research paths that would've revealed the problem or otherwise knowingly or neglegently hindered proper research. Now if your doctor doesn't tell you about the potential downside, that's an issue.
The "statistic" that prescription drugs are the fourth leading cause of death in america fails to take into account half the reason: they also reduce most of the other leading causes of death.
Or rather the experiment you pointed out is technically correct, but it does not fully model the situation. In fact, without any followup at all to that expermient describing more complicated circuits or at the very least, mentioning their existance, I would say that your high school cheated you.
In your frankfurter experiment, The voltage was the same across each of the dogs and so the only thing that was different was the current as a result of the conductivity of the sausages. In this case, P = VI = V^2/R for each of the dogs.
If you had connected the hot dogs in series, like this:
You would create a voltage divider network. The analysis for which goes like this: The current through any loop in the circuit is constant (e.g. the same current would be going through both the dogs, but the voltage supply would "see" a higher overall resistance so the total current would be less than in either case.)
In this case, the largest voltage drop is across the higher resistance. since the current is the same through both, the generic dogs will dissipate the most heat in this isntance.
Imagine cutting the generic dog to a length that made it less resistive than the ballpark. In this case, the total current would increase from the previous, and the ballpark would have the large voltage drop.
A simple power supply regulator does just that: it puts a resistance in series with the load and adjusts that resistance so that the voltage across the load is the same no matter the load. This presents some serious efficiency issues when the unregulated voltage is significantly greater than the desired voltage.
In fact, the IC is more complicated than that, introducing parallel and series parallel circuits, and transconductance elements, capacitance and even quantum tunnelling, but suffice to say, in general, the lower the wire resistance, the lower the fraction of heat disipated by the wires themselves.
Multiple links are not sufficient to point to a single target. Often there are several words highlighted in a sentence, any of which have an equal chance of being "the article" due to the hyperlinking of articles and other common words. I might want to read all of them for context, but I might not be interested in the sidetracks the summarizer thinks are relevant or funny.
No i'm afraid it's only 24 bit resolution of doneness. The toaster itself is capable of 32 bits of RAW toasting, but the dominant OSS toasting application developers inexplicably have shown little interest in expanding capability to the full dynamic range. It does however, toast very quickly by taking full advantage of the entire 64 amp power bus.
Now hang on, I've been to the "coke from around the world" pavilion at Epcot and the various cokes taste nothing like our coke. Additionaly, though probably due to conditioning, they taste horrible. Some are undrinkable.
The solution isn't that we need to tax "the rich" more or even that we should be going after the "Martha Stewarts" (who was specifically a high profile scapegoat and nothing more*)
These aren't the solution, because you've misdiagnosed the problem. Specifically the inherent failings of the "corporate savior" model of ceo choice. People believe they need some kind of superman to 'lead the company and establish new paradigms' or somesuch. It couldn't be further from the truth: a well run company needs to have capable leaders all around. If management is incompetant, no great CEO can save them and if they're not, the best thing the CEO can do is get out of the way for the most part.
Should CEOs be paid the huge amount they are? of course not. Paying the huge salaries we do weakens the company they are supposed to be leading. The salaries are the result of believing the pool of acceptable leaders is small. (much like the diamond trade come to think of it) By realising that the team can do more of the decision making and choosing from a larger applicant pool companies could save a fortune on top-heavy expenses.
So why don't they? The people who seek out the CEOs are either high paid top level employees to begin with or they are high paid external consulting groups who have no interest in dispelling the myth of the corporate savior. The shareholders are too busy with their lives to take active interest in choosing of applicants (though they may have time to vote on one of the high-priced candidates put forth by whatever committee does these things) so they're kind of stuck.
The solution: As soon as a company that eschews the uberCEO begins to dominate whatever market it is in, Other companies will have to follow suit (or convince the leadership to fall to the dark side) It is imperative to such a business model that the leadership be well distributed to make that enticement more difficult. I suspect that it will be difficult to nuture such an organisation, but should it come to exist, no one will be able to compete with it in its market without doing the same.
Taxing people for making more money doesn't discourage companies from throwing money at them. It only means the government gets a bigger cut of the wasted money. I think we can all agree that the one thing the government does not need is more money.
*Don't you find it odd that she was convicted of misleading investigators on an investigation of herself which didn't result in any charges being brought forth?

She took the big public fall so a lot of more powerful people wouldn't have to.
Yes, I failed to mention the effects of DC converters and such.
The board may sample at a million hz and report data every second, but if he just takes average |V| and average |I|, the million hz is useless. If the board is calculating the power at every sample and reporting it to his machine, that's a different story altogether.
From my reading of TFA, it appeared he was only sampling and and multiplying them in his computer to determine the
over the interval. No mention is made of whether the board is capable of a calculation.
I'm still a little unclear on that point: The board has current transducers, but where is it getting voltage information?
Actually it doesn't. The atmosphere is what protects us from solar wind particles. The magnetic field just redirects them so they impact with increased concentration near the poles rather than spread out over the whole earth. Since people live in Canada, alaska, siberia, finland, etc. The high level is 'safe' the much lower level earthwide aurora would be entertaining, but that's about it.
This the key thing to remember about films. It's as they've always been: a movie is more like a diorama than a play.
In a play, you need good actors because "remembering lines" is the easy part. Convincing the audience of a new reality on an artificial platform thirty feet away is the hard part.
In a movie, the audience can be visually much closer to the actors. This suggests an immediate trade-off that must be done: You need the "best-looking" actors you can find because you're zoomed in the whole time and the show is exactly the same every time its played. It doesn't matter as much if they can't act because you can keep filming each scene and molding actors into the scene you want until it's good enough, then just use the best one. It's sort of the "Million Monkeys" approach to filmmaking, only separate "models" for monkeys.
If your pool of actors is limited to the set of {Models who have talent} you're going to have to pay the more than if you use the much larger pool of {Models}.
I have no good explanation for the phenomenon of "stars" in this framework. Their tendancy to be typecast suggests that some branding is going on here, but there's no good reason to pay someone $20 million to look good in a 90 minute film when there're plenty of people capable of looking good for 90 minutes for much less money.
Not to worry. It's almost certain to be far from free.
I'd like to see a geothermal based economy. As we cool the mantle, we can just keep digging deeper, opening up deep mineral resources at the same time. On a large enough scale, vulcanism would be reduced. It's a win^3 situation.
Save the fusion for nuclear rockets, we're going to need off planet energy source once the geo runs out. (or we're going to need to be gone assuming the sun goes red-giant on us before we run out of latent heat)
In other words, (Vrms*Irms)^2 = Pre^2 + Pim^2 It is not the real power.
the real power is equal to Vrms*Irms*cos(theta) where theta is the phase angle. between V and I.
You can also calculate the real power by the integrating square of the instantaneous product of V and I over one full cycle
Prms = 1/T*sqrt(int(t0->(t0+T),V(t)^2I(t)^2dt))
It appears from the article that he is measuring V and I (rms? average? sample? doesn't say) of one-minute intervals. Since he appears to be close to the actual power recorded by the meter reader at the end of a month, we can assume that the sum of the reactive loads in his house is small. I'm sure the power companies are happy about that.
In fact he must sample at greater than 120hz* to get meaningful results. He has neglected the possibility that voltage and current can and will be out of phase for each of the loads in his house. Without determining the phase difference, there is no way to accurately deterimne the average power over any interval.
There are quite a few meters that measure RMS voltage and RMS current, (though most of the cheap ones actually measure peak values and multiply by.707), there are fewer still that accurately resolve power factor
This is a common mistake to make for first year EE students and "over-unity" power converter proponants.
*I know you need 2f according to nyquist to resolve the frequency, but I'm not sure what you need to gather the phase information**
** There are other ways to obtain the phase information involving bridge circuits and such, It does not appear that the boards in question provide that information.
Most of the windows disks that ship bundled with computers are actually (compressed?) disk images of the complete operating system for that specific machine. Reformatting and reinstalling is as easy as:
1) insert recovery disk 2) reboot computer 3) hit enter for OK at the prompts. 3_1.._n) do same 4) activate windows update and install everything
(some machines have a recovery partition instead. I think that dells are going this way. In this case it would be a matter of hitting delete or a function key or something during startup to get the boot menu and start step 3)
Of course you lose everything, but if you think the internet is the blue e, most of what you're going to lose is in the "my documents" folder for easy backup.

Bush Administration with agenda + UK intelligence vs. Self-important ambassador with agenda
I only know that Bush claimed that Brittish intelligence believed Saddam Hussien was attempting to purchase uranium from an african country. Later, the former US ambassador to Iraq returns from Niger claiming that Saddam was not looking for uranium in Niger.
Niger accounts for roughly 4% of the land area of Africa. Even assuming Williams actively sought out the information he claimed and that he was absolutely correct rather than that he just hung out with his diplomat friends at the ritz embassy hilton, This still does not refute the original claim of AN AFRICAN COUNTRY.
He cleverly did not claim that bush even meant Niger, He only strongly implied that Niger=Africa. This leaves him a clintonesque 'out' in the event that irrefutable evidence of a transaction is eventually uncovered.
Until the original evidence is revealed to the public, we will not know if the british were correct or if williams sufficiently refuted their intelligence. In the absence of any real evidence, I choose to believe my president over a former ambassador. Especially knowing that it seems to be a criterion for ambassadorship that you be a thorn in somebody's side.
