Comment Re:And? (Score 1) 195

The frontal area to mass ratio of a train is tiny compared to almost every other form of transport, so that's less of a problem.

The limiting factor with trains is usually the track, for really high speeds you need to almost completely smooth out the bends and flatten the hills, the impressive part of the jet train is that it went so fast on a track designed for much, much lower speeds.

That all makes sense, but it doesn't seem to match up to the observations.

The article says neutrons were observed arriving hours before optical photons, but what you are saying is that photons of high enough energy to become temporary particle pairs should arrive later than lower energy ones, which don't get slowed down by temporarily dropping below c.

If the chance to become a particle pair varies with energy, we ought to see the supernova change colour, starting off shining brightly in the visible spectrum only, then gradually becoming bright at higher and higher energies, as higher energy photons emitted at the same time as lower energy ones arrive progressively later on.

Comment Re:The Problem Isn't "Free Speech vs Privacy" (Score 1) 278

Just to clarify the EU court ruling didn't say:

1. You have no right to be forgotten by the Newspaper that published the story
2. You have a right to be forgotten by search engines.

It said something like:

You may have a right to be forgotten if your right to privacy in certain information outweighs the public interesting in knowing and accessing the information, and if removing the information from a search engine is a proportionate response.

EU law is often drafted in terms of proportionality, and the CJEU doesn't usually rule on the facts of a case, just gives guidance on interpreting the law. The key parts were that a search engine didn't have immunity just because it didn't host the original content (it was still processing data) and that just because the information was still available on a website didn't mean that removing it from a search engine was necessarily a waste.

I think that Google did make that point; it is Question 2(d) of the reference, and dealt with in paragraphs 62-88. I think whoever wrote that line meant to say that they'd failed to convince the Court of that point, rather than that they hadn't made it.

Imho this ruling isn't as "evil" or "censorship-based" as some commenters have made out, but also isn't nearly as pro-individual privacy.

As with most EU law, it comes down to proportionality; balancing the gain to the individual's right to privacy by removing the search result against the trouble to remove it (very low weighting) and the public's freedom of expression/right to know it (can vary).

In theory this is great; you and I can get the awkward things we did when we were young scrubbed before they turn up with job applications, but evil corporations can't use it to bury their dirty secrets, or politicians to hide uncomfortable pasts.

In practice, however, this kind of balancing is very expensive to do - and the Court seems to be encouraging direct claimant/search engine interactions (rather than going through the domestic courts), so we could see search engines just agreeing to take down everything they're told because they don't want to pay to fight or even examine the claims - as with defamation or copyright claims.

[It's also important to remember that this is a ruling on a 20-year-old law, the law technically hasn't changed, this is just the first time the CJEU has been asked whether search engines "process" personal information etc..]

Erm... Google did have standing. You can read the judgment of the court here.

Google was represented and their arguments are referred to throughout the ruling. Also represented were the Spanish, Greek, Polish, Austrian and Italian Governments, and the European Commission.

I don't think that it is possible to appeal Grand Chamber judgments in preliminary ruling applications such as this, but I could be wrong.

Comment Re:...the first rigorous proof... of unprovables. (Score 1) 612

I'm sure the math can line up to make it "work" on paper but how exactly does one test such things?

You look for consequences of the theory. Things that would happen as a result of this, but which you won't expect otherwise.

A great example being the recent announcement by the BICEP2 people. The theory they were working on was inflation - which made the maths work on paper, but happened billions of years ago so was hard to test. But the theory predicted that inflation would have caused an "imprint" of gravitational waves in the microwave background radiation, something unlikely to happen otherwise - and these people were able to detect this imprint.

This is how science works sometimes. The theoretical physicists come up with a theory, the mathematicians prove it is possible and the experimental physicists find some consequence of the theory that can be tested.

Comment This would fix bait and switch adware games (Score 1) 199

It seems to be an increasingly common tactic for games developers to put out an advert-free game, wait for it to gain market share, then force an 'upgrade' that has no improvements at all, but is crammed with so many adverts that the game is barely playable. I deleted "4 words 1 picture" when it turned into "4 words, 1 picture, 1 full screen advert", but I would rather have kept the old, playable version on my phone.
