Comment Re:There are US DHS at London Gatwick?? (Score 4, Informative) 704

That doesn't ring true. The UK does not need visa approval for US travel. Anyone with a British passport is part of the visa waiver programme, allowing entry to the US for up to three months (plus another three with an extension if you're rich enough), per year. The exception to this are those on the banned list, i.e. criminals and those with suspect pasts from other countries.

Yes, but those on the visa waiver program do need to apply for this in advance of travel via the Electronic System for Travel Authorization (ESTA)

From TFA: "They’re usually hit from behind in slow-speed crashes".

If this is in fact the dominant accident mode, I would suggest that this is not such a big deal and will, over the long term, be self-correcting as the insurance rates for idiot non-automated drivers shoot up because they can't get it through their thick skulls not to tailgate other vehicles.

So, what's happening that makes tailgaters hit the driverless cars more often than driven cars?
Are the google cars suddenly slamming on the brakes in a way that humans don't generally do?

On the other hand, as is the case for a mayor on the list, it will be clear that they don't belong on the list..

It won't necessarily be clear for everyone.
For the gay democrat most people will think his inclusion was a mistake.
But if somebody on the list is a right-wing republican white man, but not a racist and not a member of the KKK, it will
probably be very difficult for him to convince people that his inclusion was a mistake.

It is not an error-state, it is Siri's new job as an Apple sales person rather than an information service.

Coming up: "Siri, what is the time?", "Sorry, I can't tell you that because you don't have an Apple watch"

The traditional form of the "joke" would be:

"Siri, what time is it?"

"Time you got an apple watch!"

It's not like they are using real-time data from this thing - it's more like a traditional particle smashing experiment where most of the analysis is done months and years after the data is collected.

Well, in some cases the detection of a high energy neutrino has triggered a search for a counterpart at other wavelengths (X-ray, optical etc.).
So near real-time detection of a neutrino can be important to determine its astrophysical origin.

And from the ANTARES neutrino telescope:

when the suits don't listen to the nerds, I'll bet. I'm sure at some point someone in engineering said that this was wrong, that they shouldn't cheat like this. I'm sure he/she was quickly told to drop it or start looking for a new job.

Or could it have been the other way round?
The nerd(s) had a quick cool hack to satisfy the emissions tests while providing better performance, and didn't want to listen
to the boring lawyers in suits...?

Comment Re:An honest question (Score 3, Interesting) 72

The expected main sources of gravity waves are things like merging binary "star" systems where the stars are actually black
holes or neutron stars, and supernova explosions. However, these are relatively rare events.
So, for a gravity wave detector to see something, such an event must take place within the volume of space
where the detector has the sensitivity to detect something. That means for the original LIGO to detect something
we would have had to have been very lucky to have seen something.
With the upgraded version, the volume of space where LIGO will be sensitive is greatly expanded.
We have educated guesses for e.g. the occurrence rate of merging black holes. That can be used
to estimate how likely it is that a gravity wave detection would be made within a certain period of time
The current estimates give advanced LIGO a good chance of detecting something. (I'm too lazy
to check the actual numbers!)
So, if nothing is seen within a few years at the final sensitivity limit then people will have to reexamine
their estimates of event rates and/or general relativity.
