One of the mental problems that I think people get in this area is that you can't help but mentally imagine that there's just these few points of data that we need to hit, and so we have a lot of freedom in how to construct formulae that match the observation, so why are scientists being so obstinate about the possibility that MOND may be true?

But that's not the case. We have petabytes of data from space (if not more). Your theory needs to match all of them, give or take noise. The common example of the Bullet Cluster [1] comes up a lot, but it's just one particularly exciting example of the problem. I've seen people create variants of MOND that try to address the Bullet Cluster problem, but you start having to have some sort of really weird gravity memory effect in space or something, where space itself "remembers" that it used to have a lot of matter in it and still has a small amount of gravitation in it despite no longer containing the corresponding mass. Which I suppose isn't necessarily out of the question given that we're intrinsically discussing a non-linearity in gravity, but it's still a bit strange.

By the time you work out what MOND is going to need to look like in order to explain everything we see in space, it ends up losing its "Oh, it's just one more simple term on gravity" nature and starts looking pretty weird itself. It's constrained by the real data to be at least as weird as dark matter itself, because the data itself is weird. Given the history physics has had with "calling its shots" and identifying the necessity of particles years or decades before they are detected, dark matter is something that I consider at least not out of the question.

I also am sympathetic to MOND solutions as well. After all, "the math looked awfully weird by the time we finished working out the theory" also has a long and illustrious history in physics too! What's true is true, regardless of how we feel about how beautiful it is. We also have a Standard Model of particle physics that, whatever its known flaws may be, doesn't immediately obviously have a hole for dark matter in it, so perhaps the "we've called our shots before" argument doesn't apply so well here. There is something to be said for not trying to push a new particle in there. But if MOND is the answer, you're likely to find the final result to have non-trivial weirdness in it, too.

I think the electoral college is probably the worst approach. The original intention behind the electoral college was basically to overturn the decision of the people if the wealthy elite didn't like it. That's translated into "preventing mob rule". Why not just make sure the mob is actually capable of picking their own leader, or even better teaching them to lead themselves?
There is another possible explanation instead of dark matter and that is electric charge and currents (plasma flows).

Electric force is many orders of magnitude stronger than gravity. So, if the objects in the universe are charged, the repelling force between them could account for the expansion acceleration in a very simple way.
I asked an Intel chip designer about this and his opinion was that asynchronous processors are a "fantasy." His reasoning was that an asynchronous chip would still need to synchronize data communication within the chip. Apparently global clock synchronization accounts for about 20% of the power usage of a synchronous chip. In the asynchronous case, if you had to synchronize every communication, then the cost of communication is doubled.
There used to be this theory of Phlogiston, which was a material substance of heat (if you put a lit match under a brick, phlogiston would move from the match to the brick.)

Today of course, this sounds ridiculous. But my physics teacher was always keen to point out that the people involved weren't stupid and that it was an important theory because it was a good starting mental model of how things actually worked and led to our better understanding today.

I wonder if dark matter is similar. It's not flat wrong, it's the best explanation that we have so far and in it will lead us into another breakthrough of understanding.

They're not violating the treaties, they are saying if EU citizens come after a certain date then their residency is not guaranteed.

EU citizens will be free to come right up until the UK exits the EU but those that came after said date will likely have to apply for visas. Those before will keep residency.
I agree. There already was a (failed) "Romanian invasion" several years ago. Furthermore, the recent events & decisions have given the UK, at leas in my immigrant eyes, a relative sense of insecurity. I would personally not relocate without knowing how the brexiters would react towards immigrants, regardless of the legality of their stay.

It's hard to say from reading the article, and I may have a hair-trigger these days for left-wing hatred and intolerance, but it's genuinely hard to tell here whether Sam really wants to listen to people, or to convince them to adopt his political position. Questions like "What would convince you not to vote for him again?" come off as pushy and leading in this environment.

We have such a strong divide in our country these days. I think we should all ask ourselves if we're working to heal the divide or increase it. It's very easy to call others intolerant. It's not so easy to let go of the intolerance in your own heart.
So this doesn't actually get into the actual big issue with MOND which is that observational results [1] tend to imply some sort of dark matter so current MOND theories actually include some dark matter, just less of it.

> Yet another attempt to emulate a full OS-level network stack on top of HTTP

The proposed protocol does not work "on top of" HTTP. From the article:

> The basic idea is that the web backend performs authentication and when a client wants to play, it makes a REST call to obtain a connect token which is passed to the dedicated server as part of the connection handshake over UDP.

So both the handshake and the actual data transfer happen directly over UDP.

Next:

> Giving random web-pages access to RAW OS-level networking, and not just sockets, from untrusted internet JS.

The "Why not just let people send UDP?" section in the article actually explains why that would not be a good idea.
Why wouldn't they stay, legally or ilegally, in the equally rich Germany, France, Netherlands, Belgium, Sweden, Finland, Austria? All of which are closer to the origin countries than the UK.

Ah, the 85 page form with the £65 fee, which many of my friends are worried they'll not be able to fill in correctly -- especially after all the stories in the British press of the long-term residents whose applications were rejected.

For comparison, the Danish form for permanent residency has 6 pages in English (and 6 in Danish, it's bilingual), no fee, and only requires copies of the last few tax returns and a current job contract. Unfortunately, even if Britain remains in the UK until, say, 31 March 2019, I'll still be a few months short of the 5 year requirement.

HOW BLIND ARE THESE PEOPLE? What reality are you creating where you cant see how your contradicting yourself with your own words? Trump did not generate one iota of "Intelligent Debate" throughout his campaign, and never rose above the dull level of "Character Assassination"!

The United States is not a welcoming place for EU citizens. Immigration is strictly limited, the procedures expensive and time-consuming. If that's the bar for the UK government, the grandparent poster is right: it's not going to be worth even looking at Britain.

To put it another way: if working in London, New York and San Francisco are going to be equally difficult to arrange, I'm not sure why anyone would prefer London. Housing is as expensive as NY or SF, yet wages are much lower. The weather isn't great either.
> Ok, but physics has had a long and fruitful history of inventing invisible stuff when theory and results disagree

Inventing and then testing, though. As you said, GR got a huge boost last year, still being tested a century after being proposed. That's how science should be!

We know the darkX behaviour and we have some ideas as to explanation, but far from being proved in the way GR has been.

Dark energy, dark matter, string theory. Lots of IQ being poured into them, with a reasonable chance they're not the answer.

Practically speaking, some first world countries might be able to hold US citizens in disdain. But for much of the third world the US tourists are big source of revenue and non tourists are usually important people on government or private business.

I understand that for foreigners to see trump sworn into office and then all of these stories pop up would make them think america has changed so recently, but its not true. It like an episode of the Twilight Zone.
The actual 'credibility' is at an all-time high. Today's mass media is better, in terms of adherence to the truth, diversity, and creativity than at any point in time.

...and it's also fairly easy to forsee that this rush will not happen, if, during the negotiations, the economy in britain goes further down.

But we will only know for sure in two years.

Anyway, I would have expected that there was a bigger rush up until the Brexit vote, when the British economy was very good and moving there seemed to be a safe bet (because it was in the EU and you could stay indefinitely).

The "funny" thing is that we are heading to a situation where the "positive" discrimination in favor of women will affect the weak side, the black/brown man, and they are not privilleged, of course. Now we have double negative discrimination.

BTH, if it wasn't so common for women to waste lot of hours everyday with cosmetic and aesthetic stuff, they would have more time to study computers and suffer less harassment. Win-win.
> "You'd have a really good engineer who wanted more money and more status and recognition, and it took him away from being a really good engineer and often into being a really bad project manager."

Exactly. So many engineers follow a default career progression into management, and then end up losing their edge from replacing an IDE with excel spreadsheets and powerpoint, and going from meeting to meeting all day.

This also results in folk being managers, who do not have the skill and character needed to manage people.

(I have a physics degree, but it’s very rusty at this point)

Particle physics has a long history of noticing gaps in the experimental data that don’t match up with current theories and positing that maybe a new particle would solve the problem. This goes right back to things like the neutrino (which was posited to preserve momentum in certain particle interactions IIRC) and even the neutron.

Sometimes the suggestion pans out, sometimes it doesn’t. You can see this kind of thing in action - when there was that anomaly in the CERN data a year or two ago there were a flurry of papers suggesting possible particles, none of which panned out because the anomaly turned out to be statistical noise. The various particulate explanations for the observed discrepancy between the spiral galaxy rotation curves and the observed distribution of matter are very similar: Take a gap in the data & speculate about what kind of particle would fill the hole.

When you combine the fact that, historically, speculating about whether new particles could explain anomalies in the observed data has been very productive for C20th physics with the reality that physicists are also loath to toss aside general relativity (which has been spectacularly successful) just because of one observed anomaly that has yet to be explained, it’s entirely unsurprising that physicists are keen on new particles as explanations for the galactic rotation curves.

At the same time, every physicist will happily admit that there’s a great big hole in the standard model - i.e. that it doesn’t include gravity at all - and that any unifying theory might also explain away the galaxy rotation curves in a way that doesn’t require new particles. Indeed, if a unifying theory could pull off that trick it would be evidence that the theory has a good chance of being true. Sadly, to date, no one has managed to come up with such a unification, and we have no real idea what such a theory would look like beyond the obvious: that it should explain the observed facts & match QFT & GR in the regimes where those theories are accurate.
Is there something wrong with the agency making a public statement refuting the allegations, citing the information they have (but without specifics for privacy reasons)? Surely that helps them without their having handed over information?
