Follow up to my own post.

The fact that you cannot measure the momentum and location of a particle exactly is NOT a limitation imposed by measuring apparatus. The fact is that a quantum particle HAS no exact momentum and location, as a result of its wave function.

Your explanation of Heisenberg with the inability to observe is incorrect. That's a RESULT of Heisenberg.

Heisenberg's Principle comes out of the wave/particle duality. To localize a particle, you have to add waves of differing frequency to its wave function (ala Fourier). The more you localize it, the more waves of higher frequency you add. Momentum is derived from the wave frequency. Therefore, when you localize a particle, you are increasing the uncertainty of the momentum (by adding more and more higher frequency waves).

This is the argument that Heisenberg used (yes, I've read his book).

Pre-existing condition exclusions are required because of adverse selection. Flood insurance works the same way; you've got no coverage at all until the policy has been in effect for 30 days. If your house washes away on Day 29 you're SOL.

In any case, I didn't share my story to indict the insurance companies. It was more of an indictment of the healthcare system in general. There was one unavoidable expense: the $4,500 immunoglobulin shot. Why then did the total bill come to nearly $7,000? It came to that much because treatment was routed through the most expensive delivery system (the ER) available in our healthcare system. Why is that? The rabies series is not time sensitive, waiting a few days causes no ill effects. The taxpayers ostensibly pay for it anyway so why not just have it at the County Health Department Monday through Friday?

I try to route my healthcare through my PCP, because 1) I like him, 2) It's cheaper (both for me and society) than the alternatives. Of course, we're killing the PCP providers, they're barely paid cost as it is (less than cost for medicare patients) and there's no incentives for med students to pursue primary/family medicine as a specialty. The ACA didn't do anything to address this either, a fat lot of good having insurance for the first time is going to do you when you can't find an MD that's taking new patients.

Wikipedia has a nice table of the relevant data. Per capita statistics are a bit misleading as they don't count for different levels of car ownership. Per vehicle statistics are a bit better. The UK has 6.2 fatalities per 100,000 motor vehicles (per year), whereas the USA has 13.6. Generalising this to 'Europe in general' doesn't really work though: Greece, for example, has 13.8 and Portugal has 18.

Even that doesn't tell the whole story though, because people in the UK laugh hysterically when we hear how long people in the USA think a reasonable daily commute is and so cars in the USA are likely to be driven further, which might account for the difference. Taking that into account and using the numbers for fatalities per billion km driven, the UK has 4.3 and the USA 7.6 , so under twice as many. As the grandparent said: not too far behind.

That's a valid point but you kind of missed the bigger picture. With my history and health status they shouldn't be on the hook for more than $300-$500 annually. That's the cost of an annual physical and standard blood/urine lab work. All it took was one incident to largely wipe out their earnings on me and in this case the costs really weren't inflated all that much. Despite what the other poster thinks, the immunoglobulin really is that expensive. It has a very short shelf life, production is a bitch, and there's little economy of scale because it's so rarely needed. Socialized medicine won't fix any of that....

I can only assume that you rarely talk to non-geeks. I upgrade my phone roughly every 3 years and most of my non-geek friends have significantly older phones than me. Many of them get new phones only when a geeky relative upgrades and hands down their old device, so the least technical users end up with the least secure devices...

Because you can make more money if you invest more capital. If you have a project that has a 10% annual ROI and have $1m in the bank, then you can double your money if you use that as collateral and borrow $10m to invest. This is a big part of the reason why money tends to concentrate in the hands of people who already have money.

Yes, since the bills would be covered by insurance.

After the deductibles and co-pays. I have a "platinum" plan through my employer; better insurance than anyone else I know and the co-pays still total up to a considerable amount. No deductibles for in-network on my plan, which makes me extremely fortunate. As a single guy I can afford the co-pays even with my modest salary but I can see how quickly they would bankrupt someone with a family, particularly if said family had one or more members with a chronic illness.

Incidentally, I was just exposed to rabies a few months ago:

Strike One: The only place to get the immunoglobulin is the ER, because it's very expensive (>$4,500) and has a short shelf-life. ER co-pay: $150
Strike Two: There's a set schedule for the vaccine, Days 0, 3, 7, and 14. You can get the vaccine from your primary, in theory, but of course my primary has a months long waiting list because we're driving PCPs out of business. Bottom line, I can't get appointments with them for Days 3 or 7, so that's two more trips to the ER. Additional co-pay total: $300
Strike Three: New York State ostensibly has a fund to pay for out of pocket expenses related to rabies exposures, but they only reimburse for the rabies vaccine and immunoglobulin. Since the ER decided to give me a tetanus shot on Day 0 NYS won't reimburse me, even though my out of pocket would have been $150 with or without this extra shot. Hooray for bureaucracy!

Totaling all this up, that stupid bat that found its way into my apartment has personally cost me $465 ($450 of ER co-pays, $15 of PCP co-pay) while my insurance company is on the hook for close to $7,000. My annual premium is about $6,000. So this one incident wiped out every penny they made on me and then some. I'm an otherwise healthy 32 year old marathon runner that ought to be subsidizing those who are less fortunate. Now imagine a family of four that were all exposed to the same scenario I was.....

Let's look at it another way. Some Aztlan nutjobs somehow manage to set up a base of operations in Tijuana, and say that they want California "back".

They start by sending in suicide bombers to San Diego. The Mexican government does nothing to stop them. They launch rockets into San Diego and Orange County. The Mexican government does nothing to stop them.

Assuming this scenario, what should/would the US government do?

The reason that most extensions exist is that there is (or was) no way of implementing things that people want with standard C. Inline assembly is one example. All modern C compilers support it, but GCC and Microsoft's compilers use different syntax (most other compilers implement one or the other, sometimes both). Without it, you require that every time you want to use even a single instruction of platform-specific assembly code, you must write an entire function and call it.

Atomics were another big reason for extensions. Prior to C11, if you wanted atomic operations, you needed either assembly or non-standard compiler intrinsics. Efficient vector support is another one.

In case of injury notify your superior immediately. He'll kiss it and make it better.
