Comment Re:Free market economy (Score 1) 529

Markets in poor neighborhoods carry what 'poor' people buy

They buy what gives them the most calories per dollar, while also focusing on foods that require the least preparation time (since their work typically leaves them with little time to spare). End result: saturated fat, refined sugar and sodium, with very little in the way of necessary vitamins and minerals.

Poverty is now owning... a car out of warranty!

For most of the United States, owning a car is a necessity for both working and buying food.

Nothing is objectively known about the airliner. Everything, from Ukrainian air traffic control ordering the plane to descend to a dangerous altitude to who detected what, is all supposition and hearsay at this point.

It is my personal suspicion that the Ukrainian authorities were hoping for an accident of this sort and were intent on placing a civilian airliner in as dangerous a position as possible. Whether that was the case for this specific airliner on this specific flight is unclear.

And I'd argue that Korean Airlines 007 is a better example for this reason. The US had been using civilian airliners for spying on Russia for some time and doctored the evidence to remove Russian pilots radioing warnings to the aircraft in order to make the incident more incriminating than it was. Whether that flight was used for spying, was shadowed by such an aircraft, or merely happened to be in the wrong place at the wrong time, all becomes incidental. The accident was inevitable and the US government of the time was guilty of ensuring civilians would someday die for the benefit of military intelligence. It was merely a matter of which plane would be blown out of the sky and when.

In this case, the Ukranian authorities deliberately downplayed the risk of missile attacks on overflying aircraft and deliberately worked to place aircraft in the most dangerous air corridors that the airlines would permit. That is indisputable. Their opponents were known to be firing on aircraft and had shot several down. When your time to respond is measured in milliseconds, the nearest aircraft identification guide is mere hours away, to paraphrase what Americans often say about cops.

An accident was inevitable. The separatists weren't interested in avoiding one, the Ukrainian authorities certainly weren't. It was merely who would die for someone else's ideals. Whether or not this aircraft was deliberately placed in the path of a SAM battery is unimportant.

Both sides are therefore guilty. Both sides deserve blame.

Comment Re:String theory is not science (Score 5, Insightful) 147

It's testable, it's measurable, it's repeatable, it's capable of prediction. it's either the simplest model that meets these requirements AND produces correct predictions, OR it is not.

Therefore it is science.

Maths is a science, for the reasons given in the first line. Science is a mathematical system, because ultimately there is nothing there, just numbers. (See: Spinons and other quasiparticles.)

Comment Multiverse theory (Score 4, Informative) 147

There are many multiverse theories and they can all be tested.

Many Worlds: The theory that there are no real "probability waves" in QM, merely overlapping realities that diverge at the time the "waveform" collapses.

This is an easy one. Entangled particles operate using the same physics as wormholes. If one of the entangled pair is accelerated to relativistic velocities, say in a particle accelerator, they will not exist in the same relative timeframe. It would seem to follow that if Many Worlds is correct, one of the particles will be entangled with multiple instances of the other particle, which would imply that every state would be seen at the same time. If the options are left spin and right spin, you'd see an aggregate state of no spin even if no spin isn't a physical possibility. And seeing something that doesn't exist either means you're in a Phineas and Ferb cartoon or Many Worlds is correct.

Foam Universe: This is the sort described in the article.

Yes, impact studies are possible, but they're only meaningful if you have enough data and you can't possibly know if you do. You're better off trying to make a universe, preferably a very small one with a quantum black hole at the throat of the bridge linking this universe to that one. What you will observe is energy apparently vanishing, not existing in any form - mass included, then reappearing as the bridge completely collapses.

Orange Slice Universe: This conjectures that multiple, semi-independent, universes formed out of the same big bang and will eventually converge in a big crunch.

It doesn't matter that this universe would expand forever, left to its own devices, because the total mass is the total mass of all the slices. Although they are semi-independent, they interact at the universe-to-universe level. In this scheme, because there's a single entity (albeit partitioned), leptons cannot have just any of the theoretical states. The state space must also be partitioned. Ergo, if you can't create a state for an electron (for example) that it should be able to take, this type of multiverse must exist.

Membrane-based Universe: This postulates that universes are at an interface between a membrane and something else, such as another membrane.

However, membranes intersecting with the universe are supposed to be how leptons are formed, in this theory. The intersection will be governed by the topology of the membranes involved (including the one the universe resides on), which means that lepton behaviour must vary from locality to locality, since the nature of the intersections cannot vary such as to perfectly mirror variations in the shape of the membrane the universe is on. Therefore, all you need to do is demonstrate a result that is perfectly repeatable anywhere on Earth but not, say, at the edge of the solar system.

Not everyone "gets" that advertising is needed. In fact, click-through revenue is so miniscule that it would be more cost-effective to not saturate the Internet with ads, or indeed have ads on the Internet at all. The Internet had no advertising at all until two Utah lawyers invented spam and made a fortune promoting their book on Internet advertising. That was around 5 years after the Internet was privatized.

Almost no site I give a damn about relies on advertising. As advertising on a site goes up, the time I spend there goes down. When in England, I watch BBC almost exclusively, ITV stuff is relegated to whenever it comes out on DVD. That has been the case for much of my life. When moving to the US, I abandoned television entirely simply because of the adverts.

Linux is one of the top Operating Systems and gained almost all of that reputation and awesomeness before IBM started their TV ads.

So if products don't need advertising, the Internet doesn't need advertising and users hate advertising, then who the hell is this "everyone" who "understands" the need?

Math is all about being precise, logical.. Communicating exactly one concept at a time. Natural languages do neither.

Except math is almost never actually done that way in practice. Euclid was wonderful, but almost all modern math does not work that strictly (and Euclid really should have been more careful with the parallel postulate -- there's "more than one thing at a time" involved there). Yes, proofs are careful and detailed, but so is, say, technical writing in English. Except for a few cases (check out metamath.org, or Homotopy Type Theory) almost no-one actually pedantically lays out all the formal steps introducing "only one concept at a time".

Not every programmer deals with these [mathematical] questions regularly (which is why I donâ(TM)t think math is necessary to be a programmer), but if you want to be a great programmer you had better bet youâ(TM)ll need it.

I don't think you need math even to be a great programmer. I do think a lot of great programmers are people who think in mathematical terms and thus benefit from mathematics. But I also believe you can be a great programmer and not be the sort of person who thinks in those terms. I expect the latter is harder, but then I'm a mathematician so I'm more than read to accept that I have some bias in this topic.

Math IS sequencing. So is using recipes. That is how math works.

Math is a language. Just because you can frame things in that language doesn't mean that that language is necessary. Recipes are often in English. English is sequencing (words are a serial stream after all). That doesn't mean English is necessary for programming (there seem to many competent non-english speaking programmers as far as I can tell).

Disclaimer: I am a professional research mathematician; I do understand math just fine.
