The maths is a bit beyond me, but I would expect accuracy to be best when the satellites are widely spaced. It's basically triangulation, and when triangulating on the ground you want to choose landmarks as far apart as possible to get the best accuracy. In the worst case, if the landmarks are so close you can't separate them, you don't get a position fix.

On Earth, the satellites are widely spread across the sky, covering anything from 100 to 180 degrees depending on terrain. On the Moon, they're all in a very narrow cone - Google tells me the angular diameter of the Earth from the moon is 2 degrees, and LEO won't be noticeably wider. And of course you can't see Earth, or LEO satellites, from about half of the moon, as it will be below the horizon.

The obvious answer is by entering an account number, or some other sort of reference number, in the "value" field. This wouldn't stand out as an obvious error, as that number is supposed to be on screen, it's just in the wrong place. Of course this would require that something is also entered in the place that number should have gone. And it's somewhat surprising that the value field accepts values that large.

"Unlimited" fine doesn't mean that an unreasonable fine can be imposed. Just that it's up to the judge (and potentially the appeal courts) to decide what's reasonable.
 

It sounds like it can only do one scent at once. I really don't see the point - air fresheners are cheap, and there are even ones that rotate through multiple scents. What's the advantage of having it built into a mouse rather than a separate unit?

Surely "knowing what is expected of you at work" is quite important to getting the job done? I mean, if you don't know what's expected of you then you can get "a" job done, but it might not be the job management wanted you to do.

I don't see why not. There was a referendum in Gibraltar about becoming part of Spain, which the EU seemed happy with. Spain wasn't very happy with the result, but that's a different matter.
Now, the idea of paying people to vote a particular way in a referendum, that might be an issue - but not the referendum itself.

Should you also need a prescription at Starbucks? Or your local bar?
There's certainly a debate to be had about whether nicotine should be generally available, but "it's a drug" isn't much of an argument.

It's not working because we're trying to build the high-speed rail through the English countryside. There's lots of people object to trains running past their house (and object even more to having their house demolished so trains can run through it). There's lots of interesting archaeology, ancient woodland, rare wildlife and so on. Dealing with this means lots of bureaucracy, and expensive solutions like tunnels so people can't see the trains, diversions around historic sites, wildlife bridges, planting new (bigger) woods, etc. None of which should be relevant in the mid-Atlantic - no-one lives there, no-one has ever lived there so there's no history, and there's plenty of ocean left for the wildlife.

He could try. Newport doesn't have a directly elected mayor - if they have a mayor at all it's a ceremonial position. The council is run by a leader and 50 other councillors. So he would need to win a council seat and have 25 other councillors support him. As the current councillors don't seem inclined to support his position, he would need to get 25 of his friends to stand and win - or at least get enough to do a deal with one of the main parties. The other issue is that the next election isn't until May 2027.

If you're referring to Asimov's laws, the second law of robotics states that a robot has to obey "humans" not "the user". The people who provided the guardrails are humans, and their orders are valid. Plus the first law has priority, so an Asimov robot would take a lot of convincing to tell you how to build a bomb, as that would be likely to harm humans. And you can't invoke the second law to modify the laws themselves, not directly at least. Of course the laws are full of loopholes, or the books would be very boring.

Probably food safety. That's the usual reason for stuffing mice full of excessive amounts of food additives - if the mice survive large amounts without ill effects, much smaller amounts are probably safe for humans.

I'm surprised that tartrazine is still used in the US though. It's all but disappeared in Europe.

From Wikipedia: "Tartrazine is one of various food colors said to cause food intolerance and ADHD-like behavior in children. It is possible that certain food colorings may act as a trigger in those who are genetically predisposed, but the evidence for this effect is weak."

Despite the weak evidence, though, most big brands stopped using it, and any other artificial colours. You might still find it in the cheapest of sweets and that's about it.

The UK McDonalds does that as well. At our local McDonalds, you can:
Order at the counter (though you'll have to wait, not usually very long, for a member of staff)
Order at the kiosk, get your food at the counter, and take it to your seat.
Order at the kiosk, take a marker and sit at a table, and your food will be brought to you
Order on the app, get your food at the counter, and take it to your table
Order on the app using the numbers on the table, and your food will be brought to you

That's not counting the drive-through and take-away options. Apart from taking orders at the table, just about every possible way of ordering is available.

They aren't - time is. Everyone will see their own atom ticking out perfectly timed transitions, and everyone else's atoms ticking at the wrong speed. Who is right? They all are. There's no absolute time, everywhere - down to atomic level - has its own.

It's reaching the point where UTC is getting a bit fuzzy on Earth - the most accurate atomic clocks now tick measurably differently due to gravity and the Earth's rotation. The best you can do is take an average, call that "universal" time, and then try and work out how your local time differs from the average. If you export average earth-surface time to the Moon, it's fine for setting your watch by, but calculating corrections for scientific use will be taxing. It's far simpler to define time in terms of the Moon - though not that simple as you've got a huge planet in the sky messing with gravity.

Because most carriers change stupidly high prices for roaming. If you have a GSM phone and take it to a random country, it will probably work, and you'll come back to a bill for thousands of dollars. You can probably sign up to an international package with your carrier which puts the bill in more reasonable territory, but usually still not as cheap as signing up with a local carrier.

Unless you're in the EU of course, in which case you'll get charged the same as your home country in any other EU country. And still get charged a fortune in non-EU countries....

So a commercial business is going to turn away huge numbers of potential customers, rather than expand capacity and/or raise prices?
