The black disc in this image is not the event horizon -- it's the limit to which matter can orbit in a stable orbit. If matter moves closer than this, which is 2.6 times the radius of the event horizon, it will spiral down quite quickly to the event horizon. So this region around the black hole is pretty empty.
Petrol companies charge vastly different amounts at service stations within the same city. I've seen as much as 10c/litre difference for the same company only a few km apart.
Different countries have different taxes on petrol/diesel too, so prices will differ in different countries. There's nothing stopping me bringing my car to Germany to top it up. But I can't import from Germany without paying Irish taxes on the fuel.
I can only buy from the Irish store because I have an Irish credit card. I can't buy from the UK store as I don't have a UK credit card. Books are generally much much cheaper on the UK store.
I can browse the UK store, but get redirected to the Irish store when I try to buy something.
So the Autobahns have a sign on them where there is no speed limit. Speed limited cars will limit their speed to the posted speed limit, so driving on a Autobahn in areas with no speed limit will still mean you can drive as fast as you like in these updated cars.
... if it's true. Many countries have laws around slander and libel -- 'insults' could fit under the same laws, and the defence of them would be similar.
Saying "Putin has a big nose", then, isn't an insult, it's just a fact.
Wouldn't this then imply that sound should be able to pass, at least in part, through a vacuum? If sound itself has mass, then sound itself isn't a vacuum...
Some places benefit more from DST than others. Here in Ireland where there's only 7 hours of light in winter, DST moves those hours so those 7 hours occur at the more useful time of day. For summer we get 7 hours of night, so the change allows for better night time hours.
So here DST is very useful.
Location is everything when discussing DST, yet I've never seen a survey that links desire to keep/remove DST linked to location, specifically latitude and distance from your time-zone defining longitude. (i.e. latitude and what time local solar-noon occurs).
I think this will show an obvious correlation, should it be undertaken.
As for the heart attacks nonsense, while it can be shown that the number of heart attacks does increase on that particular day, it can also be shown the they do *not* increase for that particular week. The number of expected heart attacks fire that week is the same as any other week, they just occur earlier -- they would have happened anyway.

It's well and good, but these people need jobs. They are more likely to give them what they want than be out of the street wondering where their next meal will come from.
People's security is very important to them, and companies know this.
The best way to stop this is via the law, preferably Federal law.
It seems the more and more the meaning of the word "Freedom" and "Land of the Free" is becoming more and more watered down. And I'm not sure I'm surprised, to be honest. It seems that the USA, for everything that it does have, has forgotten about its people.
There are many countries in the world where this sort of thing just wouldn't happen. Some have laws to protect their citizens (Europe being one -- no was would the GDPR allow this to happen, for example), and some just wouldn't have it within their culture.
I do fear for the USA sometimes. Things are constantly happening there are making it one of the least free countries in the world. It's a trend that I don't see stopping. You might have missed the deadline of 1984, but I fear that's where you are all heading.
Many apps use advertising libraries from other companies, and it's mainly these libraries that collect this data. The app writer may not even be aware of this, content in the fact that for a few lines of additional code they get ads in their so e, and thus revenue.
The question here is, are the app developers at fault here, or the advertising companies that provide the libraries?
Yes, but the start of the school day changes too. So if they are losing sleep in the evening they can gain it back the next morning
The case of the article is that children on the west coast of India and children on the east coast of India are starting school at the exact same time, yet the children on the west coast have sunset an hour later, so get to sleep later. They don't get up later, though, they get up at the same time.
Add a timezone and then they get up an hour later, and thus get more sleep.
This is similar to Europe. Rigio, in Greece, is at 26.5 E, and Campos in Spain is 9.28 W, so that's a difference of over 35.8 degrees. They are roughly the same lattitude (41.4 vs 43, respectively), and they are in the same time zone.
In India's case, it's all one country. So you can understand why they might have the one timezone.
In the case of Europe, there are many countries in between these two points, so there's is more reason to have multiple time zones across here.
There are several countries in Africa that are equally as wide as these 2 point in Europe that all share the same timezone.
Yet the UK and Ireland, and other parts of Africa, that share the same longitudes as these counties has a different timezone again. Sure the "home timezone" of GMT runs though several of these counties, and these countries are an hour ahead of it...
This is a problem that needs to be fixed in many more countries that just India.

Looks like the next black hole we are going to image is going to look like the pepsi swirl logo...
Damnit... I wish comments could be edited on this...
"...Additionally, there are several little-known but extremely helpful formulas which are straightforwardly deducible from this new notation."
From the abstract on the paper:
"This leads to an overall simplification in working with calculus for both students and practitioners, as it allows items which are written as fractions to be treated as fractions. It prevents students from making mistakes, since their natural inclination is to treat differentials as fractions.Additionally, there are several little-known but extremely help"
and
"Since many in the engineering disciplines are not formally trained mathematicians, this also can prevent professionals in applied fields from making similar mistakes."
The paper itself seems quite easy to read too. It's available here: http://online.watsci.org/abstr...

I wish they'd do the same for Kobo Books...

"fancy" spam!
I suppose that depends on what the Russian Government defines as "fake news"...
Is 'freedom of speech' actually entrenched in the laws or constitution in every country?
In the US it wasn't until the first amendment was ratified.
Does it have the same meaning in every country?
Also, does the Government of every country treat it the same?

Is even closer than Mercury, on average...
"On average" can sometimes be a terrible way to measure anything, though. Many times it tells you absolutely nothing.

Considering I use my PS4 and PS3 systems as Blu-ray players, I'm very likely to not buy a console they won't accept discs in the future.
Could this spell the end for Xbox, I wonder?
...until they are made illegal.
"@elonmusk [Feb 19] Tesla made 0 cars in 2011, but will make around 500k in 2019"
Isn't "around" effectively a range?

DST doesn't alter that.

Considering that this is about mobile phones, why isn't the phone dialer on the list of exemptions?
