Comment Re:Thank you Apple! (Score 1) 461

On something tangential: "mobile phones" versus "cell phones". Where I live, "mobile phone" is synonymous with the (less common) "cell phone" - this is a well known difference in language that's been around for a long while. Its interesting to see you use the two terms with different meanings, when I would still say both devices are "mobile" phones. Considering that what you call "mobile" phones will gradually supercede "cell" phones, do you suppose we are seeing the convergence of language, here?

The distinction between a religion and a cult, to my mind, isn't the quality of their beliefs-- we all believe utterly ridiculous things. (Do you actually believe in the *electron*? Or that we're all actually collections of waves? Quantum mechanics is as ridiculous as the virgin birth-- in fact, quantum mechanics ALLOWS for the virgin birth, since everything is possible (if highly improbable) in quantum mechanics).

The electron model and quantum mechanics both are predictive and thus testable, experimentally observed, and thoroughly verified to be accurate descriptions of reality. Suggesting that belief in them is "ridiculous" is, well, ridiculous. If something accurately describes reality, how can you distinguish it from reality?

I understand that the ratings system in the US is a voluntary industry system.

In Australia, the rating system is legislated and mandatory, by various agreements between State and Federal governments. Stores can (sometimes do) find themselves in legal trouble if they sell certain stock to people who aren't old enough.

I can't remember much specifics off the top of my head, but it's certainly true that there are restrictions on the sale of DVDs and other media based on their ratings, here.

It won't work because we'd have "which path" information. You will only find superposition indirectly. No one has ever seen an object in two places (or states) at once. But the effects of an object existing in two states at once have been confirmed by thousands of experiments.

You claim to be in room C. You remember being in room C. We have videotape of you being in room C. Of course it's sensible that I believe you were in room C. You were never in a superposition, because we have measurements of you being in room C.

Now, if there was no way *at all* that anyone (not even you) could know what room you were in, *then* we would be in a regime where a superposition is possible. This situation is exactly analogous to the double-slit experiment, which I suggest you read up on. (Having not thought about it, though, I'm not sure how you'd perform the final measurement for your "room" experiment, but I'd be surprised if something couldn't be worked out.)

All said, your post indirectly touches on why the sort of thing the article is talking about is actually interesting. For very small things, like ions and photons, everything you describe about being in two positions simultaneously is absolutely true and confirmed experimentally. The kicker is that there's no fundamental principle that limits the size of what can be in a superposition. It's just that it's easier to do it with smaller objects, because it gets exponentially tricky to decouple the object from the outside environment, and erase any "which path" memory.

Really now, it's not like the iPhone is a closed black-box environment, for which no outsider can create software.

AFAICT, Apple demands that I register myself with them to access any development tools. I don't wish to do that. Thus, I am an outsider, and the iPhone appears as a closed black-box environment for which I cannot create software.

It's still about control.
