I would imagine it must have a rechargeable battery (I'd say large capacitor, but they tout how small it is), or else it would cease to send a signal if your heart skipped a beat, which kind of defeats the purpose of a pacemaker, I should think?
A capacitor would take care of that. A pacemaker uses very little power, so it can be a very small capacitor.
Anyhow, aren't there other and more reliable methods to generate small amounts of electricity inside the body, considering that the patient's heart is confirmed not to be reliable (or else why implant a pacemaker?). Temperature differentials and chemical reactions to name two.
The inside of the body have pretty consistent temperature, so temperature differences are not great. A lot of work is being done on chemical reactions, but it doesn't seem to be so easy. It has to be compatible with the body, so the more closed is is, the better. Fuel cells are by definition open.
Whatever the method, if you can imagine that it could be used to move power to implanted parts, it is being tried. Many of them are making slow, but steady improvements.
OTOH, preferences between looking at technical and social objects can be registered at, I think, three months of age. Both processes play a role, and I am not sure how you would even go about telling which played how big a role.
Sorry for the double reply, but I would like to take back the "mostly" from the first sentence of the sibling post. I have no way of knowing how much is caused by biology, and as the social process is wildly self-reinforcing, it might not even make sense to ask the question. However, I stand by the rest of my post.
You are right, the causality is mostly the other way. The tendency can be registered from three months of age by tracking how long time babies of different sexes opens looking at various objects. While there is certainly large variations within each sex, the average of each sex is clearly distinct and biologically determined.
They own the copyrights to the material they write, and should be able to (try to) charge for others, including Google, to use that.
No, they should be able to stop Google from using it if they don't like the terms. If only there was some easy way to politely tell Google not to index certain pages. Then the french newspapers could do that, if they don't want certain readers to read what they have freely put on the web.
Wall Street produces nothing, it just sucks value out of the economy and puts it in overseas tax shelters.
Wall Street produces correct* prices for companies and commodities. High frequency trading produces them faster. Whether this is worth as much as they make is up for debate, especially (IMHO) the value of having the correct prices each second as opposed to each minute or hour, but at its kernel, Wall Street are providing a valuable service to society.
*For small enough versions of "correct", but I fail to see a way to do it better.
. For starters, women weren't even allowed aboard because (the belief was) they brought bad luck
If you isolate a mostly male crew and keep them celibate for a few months, I can see how having a few women in the mix could bring... bad luck. OK, so luck is not the correct term, but it would be bad for the women, the men and the vessel. Calling it bad luck would ensure that people followed the advice.
No, it doesn't. China performs 10 times as many executions as the US. Even as a proportion of the population, China is in front (or, perhaps, behind). Or is there some meaning of "by death penalty" that I am missing?
It also depends on where the competition is situated. The US intelligence have shown their willingness to do industrial espionage, so if your direct competition is a big American company, US produced gear is as suspect as Chinese would be if your main competition was Chinese. This probably goes for most other countries as well.
One justification that actually makes sense is to avoid too many hand-overs. Information is invariably lost, and that might endanger the patient. However, that is not enough to justify 30 hour shifts.
A bit of "if I had to...", a bit of exploitation, a bit of wanting to avoid having to many hand-overs, as important information is lost, a bit of "at some point your are going to be sleep-deprived (e.g. large emergencies), so you have to learn how to cope with that".
In my oppinion, only number three holds any water, and not enough to justify 30 hour shifts.
If only we had objects with known dates, this wouldn't be a problem, as you could compare directly. The best would, of course, be some kind of annual layers, so you could count how old they are. Oh, if only there was some method or another that worked that way.
Besides, I don't really think an event that last took place 780,000 years ago is going to affect a dating method where only traces too small to be measured exist after 100,000 years.
I can't vary that much over different parts of the planet. For one hemisphere, the atmosphere is mixed on at least a monthly basis. Crossing the equator takes a bit longer, bu nevertheless, it is more or less complete after 5 years. There is some problems with sea dwelling creatures, as water might come from the deep sea, and not be in equilibrium with the atmosphere.
No, they could go back further, up to 55,000 years, I think, by assuming that the C-14/C-12 ratio has always been the same. This is not quite the case, as the levels of cosmic radiation changes, so the production rate of C-14 changes. If we have an object that is known to have a certain age, we don't need to guess, we can compare directly. However, really old objects with known dates are hard to come by. You more or less need an annual cycle going up to today, so that you have an anchored chronology. Previously, tree ring data was the best anchored chronology that could be carbon dated (I assume there is too little C in glacial ice, I don't know why corals can't be used. Perhaps sea water might not always be in C equilibrium with the atmosphere?), so we could only go back 14,000 years. Now, we have an carbon-dated anchored chronology going back 52,000 years, so carbon dating gets much more accurate.
It is quite hard to plausibly fake archaeological gold artifacts. We are much better at making gold today, so there is less silver in modern gold, which is pretty easy detect.
Most of the explosives break down to NO2(g) slowly, so detecting that would take care of them. Only the peroxygenbased ones and ANFO left, IIRC. ANFO needs a primary explosive, so you can detect that, and the peroxide based ones should be findable by their oxidizing effect (though that will give some false positives).
Are there any explosives I am missing?
Of course, explosives either commercial, in which case they could contain easily identifiable tracers (I don't know if they do, but it would seem likely), or home-made, in which case they will likely be dirty, and contain other tracers (such as large amount of NOx).
Either very close to one star (as in this case), so it is, in effect, orbiting one star, of vary far from the star, so it is orbiting the center of mass. I think both could be unstable, but so could any three-body problem, and that hasn't stopped our solar system from existing.
Before calling it greed, it would be useful to get the story from the other side.
Taxi officials say that Uber's service may not be legal since city rules do not allow for prearranged rides in yellow taxis. They also forbid cabbies from using electronic devices while driving and prohibit any unjustified refusal of fares. (Under Uber's policy, once a driver accepts a ride through the app, no other passenger can be picked up.)
So you can't call the taxi company and order a cab? Or if you do, if it gets hailed on its way to you, you will not get a cab?
Councilman James Vacca, the chairman of the City Council's transportation committee, said that the spread of taxi apps had the potential to create a "two-tiered taxi system" in the city: one for people "with fancy smartphones" who are asked to pay a premium, and one for everybody else.
The NYC TLC and the city councilors have significant concerns about this effectively siphoning off high paying customers, leaving few cabs for the lower classes. I'm not sure that's rational, but I also wouldn't call it greed.
If that was really the worry, the could make more medallions, or even scrap that system all together.
Destroying bureaucracy and greed results in efficiency improvement and human betterment.
Not necessarily. Bureaucracy is the way organisations make sure they follow certain rules, so without bureaucracy, no rules. That does not improve efficiency or the human condition. The same goes for greed: Without greed, people would not work to better their own situation, so human betterment is pretty much out of the question. The optimal amount of each is not 0, and not infinity, the trick is to find a situation close to the optimum.
As for angry New Yorkers driving the commissioners out of town, that will do nothing to remove the contracts, so the City of New York will probably end up losing a lot of law suits to the taxi drivers. The New Yorkers might find it favorable to wait out the contracts before they do anything.

We tolerate childish behavior in entieties we don't see as fully in control of themselves. Does Apple really wants to be seen that way?
