Re: isn't every star in interstellar space?

Of course not. Since every star carries around it's own envelope of "stellar space", none of them are :-)

Washington Post offers invalid cookie consent under EU rules – ICO

Re: Nothing. Nadda. Zip. Zilch.

Well, fine. But some newspapers and news sites quite successfully expand their readership by deliberately appealing to and attracting people from other countries.

As I understand it, the WP is quite a respectable newspaper, and so could well be of interest to many people in the EU who might subscribe. So whilst the WP can indeed say "Bollocks to EU", might it not be more pragmatic for them to fix their site and so enhance their overseas presence and reputation (and thereby hopefully their revenue)?

Re: quantum entanglement ... real-time communications may become possible.

Not under QM as it stands. Whilst you might argue that some kind of influence travels faster than light, no usable information does. To transfer information you need the measurement results at *both* ends,

and that from the far end still has to travel to you at the speed of light.

Re: someone will complain t

I imagine that writing "about 727 degrees Celsius" would have sufficed, which, whilst still implying unjustified precision, is at least without the two decimal places of 726.85 that make that form particularly jarring.

However, given it's an estimated upper bound, any of 720, 725, or 730 would probably have been better.

You get them to watch it, and then ask them what they thought.

Cosmoboffins think grav waves hold the key to sorting out the disputed Hubble Constant

Paul Kinsler

you're postulating the de facto existence of a fourth spatial dimension.

There is no mathematical requirement for a 3D spherical surface (a manifold) to be embedded in a 4D space. It's just that it's easier for most of us to imagine it as being embedded, just as we find it easier to imagine a 2D surface as embedded in a 3D space (rather than 3D embedded in 4D).

Some manifolds are weird enough so that an embedding in a 1-higher dimensional space is not possible (e.g. the Klein bottle is a 2D surface that is not embeddable in 3D)

Re: I once measured 61,750ish volts on an empty, unused Styrofoam coffee

Just to be picky, you do not measure voltages "on" things. Voltages are differences, so you measure them "between" or "across" things.

Re: Nobody would ever say "That was an annoying high Hertz noise"

I'm not so sure about that - some people use words like "amperage", for example, and sometimes even might talk about the voltage through something. I agree they shouldn't, but not everyone has their terminology perfect, and could quite easily have learnt it from another misinformed individual.

Brain brainiacs figure out what turns folks into El Reg journos, readers

Paul Kinsler

Re: Hang on a moment

Indeed. Remember that the journalist's version isn't the same as the actual scientific paper. In particular, the j-version tends to focus on the paper's context and its plausible conclusions, as well as soundbites from the authors or peers, rather more than all the necessary scientific caveats and details of technique present in the actual work.

Consider this sentence of the abstract, and in particular its fourth word: "Here, we identified potential sources of such persistent states by microstimulating the striatum of macaques performing a task by which we could quantitatively estimate their subjective pessimistic states using their choices to accept or reject conflicting offers."

That's about when I started. I used it because that's what a friend Bruce had used, not that there were so many options back then. I particularly remember the day-long kernel compile times... (depending on weediness of hardware).

Meet the real spin doctors: Scientists tell H2O to chill out so they can separate isomers

Paul Kinsler
Headmaster

only holds true at the very low temperatures ...

(a) "spin", as applied to subatomic particles, or atoms, isn't the same as mechanical rotation (because that is called angular momentum).

(b) the nuclear spins referred to may not be strongly coupled to the atomic motions of the molecules that (in aggregate) make up the temperature.

It /might/ be that the temperature of the water has an effect on the nuclear spins of its constituent atoms on some relevant timescale, but it isn't necessarily so.

Re: I wonder what it pays as a percentage of the research grant.

It's a little bit unclear what you're asking here. Is this a question, or a rhetorical device intended to imply something?

If it's a question, even then it's not so clear. Still, I'll have a go at providing a rough estimate at an upper bound. In the UK, a pure theory grant will be probably be dominated by the costs of postdoctoral research staff, plus perhaps 10% of the PI staff costs. Costing for a fast computer and an annual international conference is small compared to this. Under FEC, the staff costs will be 2-3 times the headline salary of those staff (max UK postdoc salary is about £40k, plus a few k extra if in London). Thus "what it pays as a %" could be roughly 30% of the total grant ... at best; if you are also costing for expensive equipment, consumables, or whatever, it will be less. Three years of 40k theory postdoc and the usual other costs might come in at about 300k in the UK; but note that German cost calculations are probably structured differently, and this experiment need not have been run on an all research-grant funded model.

Anyway, in this case the reported result /is/ real work. The reported "experimental hygiene" required will no doubt be invaluable in other experimental setups, and if somehow - in outright defiance of theoretical expectation - they do find a result they've discovered new physics. So it's a win-win scenario. And undertaken solely on the basis of expected gains in "experimental hygiene", I'd expect.

10 social networks ignored UK government consultations

Re: You don't ask supermarkets to "police" their customers, do you ?

However, large shops do generally have security guards, and I would expect that in the case of a non-trivial inter-customer fracas of some kind that that security (or the management) would intervene and try to either calm the situation or move it from the store, and, if necessary, call the police to deal with it.

I would not expect them to pretend it wasn't happening and/or do nothing, claiming it was merely someone else's problem and nothing to do with them [*]

[*] Not the least in their own self interest - that sort of thing is likely to be bad for business.

Unless there is a better way of getting some use out of it, I suppose it doesn't matter about the "misuse". Since it no longer works as intended, and can't be fixed, any new data at this point are a bonus...

AI boffins rebel against closed-access academic journal that wants to have its cake and eat it

Paul Kinsler

Re: [Nature] one has to wonder how it got that way.

I think it was always well regarded; but now there's an additional unholy feedback loop constructed by the interaction of job/promotion specifications (e.g. "papers in Nature or other high impact journals") and the publication strategies of researchers who have results of significant interest (well, even academics need a job, right?).

Since Nature is a commercial operation, you cannot really blame them for making the most of the situation. The real blame should be attributed to those who insist on simplistic measures of research success when making hiring/promotion decisions.

Academics: Shutting down Facebook API damages research, oversight, competition

Re: so heavily upon Facebook, then already their research will be skewed

Well, perhaps not really that "skewed" if their research was on the usage or effects of /Facebook/ itself... :-)

Generally authors will be quite clear about their data sources and processes. Even if they themselves happened not to discuss any potential biases, the reader can then make up their own mind.
