But they will still put out a lot of pollution, it's the nature of shipping right now. And then you look at what would happen in aggregate, and you realize that there would still be a pollution problem.

Will they put out as much pollution as the airline industry?

Open question.

I know there are about 39 to 40 million flights a year, carrying roughly 4 billion passengers. Assuming all of that would switch to, let's say, rail and shipping, what does that do to your pollution profile?

My own suspicion is that it could be made much better with rail over time. (After taking an initial hit, that would be admittedly enormous, in building out the necessary infrastructure.)

For shipping, hard to say. We don't have anywhere close to the number of ships necessary for that kind of passenger scale, so we'd take an even larger hit in the build out phase. Secondarily ships, even the new ones, would still be enormously dirty for the environment. Much moreso than trains. At passenger scale in the billions? I'd bet that the pollution profile would be somewhat lower than planes, but still a significant contributor. We'd have to go back to sail ships to make it pollution free. (Even then you would have a little pollution here and there.)

Can't think of many other modes of transport that aren't scifi or in research phases right now. I mean there are airships for instance, but that build out would take a long time because I'm not convinced we've even settled on a utilitarian design there.

Tough problems all around really. Just stopping trans-oceanic travel, or drawing it down in a draconian fashion, really does seem one of the best solutions. But it's completely unworkable in today's world. No one would cooperate with that.
Yes, that is how some parts of science progress. And I certainly don't want to diminish those contributions. But that is also the exact reason why we haven't had any mayor breakthroughs in fundamental physics in soon half a century. I don't see how an Einstein, Bohr or even Feyman could get tenure today.

In summary, if you don't explain to people what the flaws are in their ideas and arguments are they may not ever discover them.

Deplatforming makes it look like their is no logical or moral counter. It is not an explanation of why the ideas are bad. Platforming and debunking is reasonably likely to expose bad ideas as weak.
Or even better, if you can reliably reproduce the problem perhaps record yourself doing so using something like https://www.cockos.com/licecap/
Why would you expect someone calling for tighter regulation of the media to give a free pass to CNN? I would expect regulators to be a thorn in the side of any commercial television network. They're in the business of selling entertainment for profit, not upholding community standards of truth, decency, etc.
And your reply shows how selfish you are.

As the majority does not want to do as I want, I take my way, without any other consideration.

Even the catalan people is not supporting this as a majority, you're ruling without considering the 50% of catalonian people.

What's the alternative to independence if they cannot return to the status quo?
> They all probably boil down to the perspective that they are a "rich" region and they will do better on their own.

All of them? That is ridiculous. It's a region that has maintained its own language since the founding of the modern Spanish state, they clearly have some cultural differences with their parent country.
And the best things are things that sound important but that your competitors haven't offered, proving that your service is more comprehensive.
I don't think you can do anything about the wind in a <10kg design.

I saw some quads with lateral DOFs that used swashplates and piston engines in the 40-50kg class, but then you basically have a helicopter with 4x the problems of a helicopter.
One thing to note here is that the Spanish government pushed heavily on favor of the interpretation that a region that splits from an EU member state also drops out of the EU. This is a calculated move to create a disincentive.

The flipside is that Spain was pushing for this when Scotland was holding its independence referendum. So the Scottish people were told that they would crash out of the EU if they voted for independence. Now they are forced to leave the EU because they voted against independence.

It's also the isolation from regular life, the particular atmosphere of only being around other holidaymakers, stopping at various islands along the way for day trips. Not my idea of an ideal holiday, and the workers' rights + environmental situation is absolutely appalling, but I do have fond memories of the one time I went on a cruise when I was a child.
I did, but it's not realistic. Maybe passively "aimed", but not actively steered, and not commandable. And even passive aiming is unrealistic at that price, active steering increases costs by several orders of magnitude.

You can't possibly think that it's straightforward to model all those physical aspects for 16 trillion objects. We don't even have the 3-body solution solved; just predicting the gravitational behavior is unbelievably complex and chaotic. That many degrees of freedom is simply unsolvable (without quantum computing).

It's hubris to believe we can predict even basic behavior and interference of such a project, let alone intended or unintended side effects, whether known or unknown.

Because Spain is currently one of the more decentralized country in the world?

Spain created the "autonomias" in order to appease secessionists.

Not a brilliant idea given them the control of the Education(that teaches them that Spain robs them and creates fiction about their past, all while rejecting Spanish), of the Police(so their friends could close roads without consequences), put levies to shops that used Spanish in their signs and tracks and harass those kids that use Spanish in School's recess.

BTW, the secessionist want to own Catalonia, but it feels too less to them, they also want Valencia and the Balearic Islands. And if you let them a big part of Aragón.

I don't see how it's selfish. If you believe that something is wrong, it's your moral imperative to try to rectify a situation, regardless of what others think about it.
Separatist movements in Spain are dangerous for the entirety of Europe. The world is much less stable nowadays and the last thing you'd want is an armed civil-war like conflict in the heart of Europe. But i'm a Turk that grew up watching news of my fellow citizens killed by separatists on the TV so maybe i'm a little bit more sensitive to this issue.
Catalonia isn't the richest region of Spain anymore. The separate identity emerges from a distinct latinic language--Catalan--, and a history of past independence.

The perceived lack of respect by Spanish authorities of Catalan culture is a major issue. The fact that militarized Spanish police--the "guardia civil"--ignore Catalan law (which is part of Spanish law) when it comes to e.g. the use of rubber bullets (forbidden in Catalonia) against demonstrators isn't helping. The judiciary branch not prosecuting these illegal acts only adds further tension. And the right-wing Spaniards displaying Franco-era national flags with the black eagle--illegal in Spain--in their demonstrations, all the while taking selfies with on-duty civil guards only comes to show that the Spanish institutions, judiciary, executive, legislative and the military have already taken sides, and will ignore their own law to preserve the unity of the territory, even if that means dismantling the democratic foundations of the state.

There is no reason to believe that an ocean liner would be much faster today, since naval propulsion was well developed by 1952.

Not at all. Agriculture may be a large producer of CO2, but the plaintiffs are organic farmers that work hard to reduce the impact that farming has on CO2 production.
The other regions of Spain are not so much Castile lovers as you think.
The idea of "digital republic" is fascinating. Politically it may be controversial, but technically it deserves further study. As the world shifts to the nomadic, post-industrial, cloud-based societies, countries like Estonia with e-residency may become popular for people to opt-in to join countries with the best social compact.

Why should it be treated any differently than other media?

What we need is a return of the Fairness Doctrine in the US (and something similar to the EU) and application of the policy to social media advertising and news outlets. It won't stop foreign psy-ops, but it will stop a lot of the internal-originating lies and deception.

> Besides that, I don't think that there was anything big

The economy is still fucked. Spain has an overall unemployment rate of roughly 15%, and over 30% unemployment of people under 25.
Well, how would that work? First, it wouldn't be a starship anymore (well, not a spaceship, at least). Then, the main advantage it has being a spaceship, is that it can "coast" in space without running its engines for a long time. This advantage disappears if you were to try leveraging the ground effect.

That said, I imagine that ground effect helps a lot at low heights (like during the landing, and early ascent phase). It could probably help much more by deploying some sort of sleeve/skirt for the booster.

And I guess that if you just want to move your rocket a few hundred meters and don't care for the ground, you could leverage it as well.

Going back to the sleeve idea (which would be like a nozzle for the rocket, a chute or a flying saucer), I would like someone to run the numbers on that. And I always wondered if firing current rockets inside a cannon (or just a trench) would help with initial acceleration (as there is a pressure differential that helps, just like the ground effect).

> Should ... be given the same space

Of course not; but "inviting to every X", or "giving the same space" is very different from disallowing X to share the same space (especially if said client change deniers or communists are prepared to have a conversation using roughly the same epistemological tools as actual scientists). There is no onus on platform providers to ensure that every opinion gets the same attention as others; my argument is that they merely let others be.

You are not wrong. In fact, there're some suspicious that third countries support independence movements directly or indirectly. If you think about it, nowadays it's far easier to break a country from inside than starting a war.

The term you're looking for is "ocean liner". There is only one ship in the world currently officially classed as an ocean liner, the RMS Queen Mary 2. AFAICT, it's basically a cruise ship, just slightly faster with slightly different types of luxury, and it takes 7-8 nights between Southampton and New York. Probably not the fastest ocean liner one could build...
today's search engines are better than ever before at finding whatever you're looking for

IMO this is empathically not true.

Not necessarily because Google has gotten worse -- although I will argue that in some ways it has, especially by deleting or ignoring search terms that I explicitely include in my query while freely adding others that are only vaguely connected -- but because people have gotten better at gaming the system on an immense scale. Search for basic information on a topic and more often than not everything is an ad-ridden Wordpress site with lots of big pictures and ten paragraphs of SEO-optimizing fluff (because Google likes lots of text to harvest keywords from) before the actual information. Google has utterly failed at de-prioritizing all this useless nonsense, probably because they make money from ranking it high.

I have to work much harder now than ten years ago at getting Google to return useful information.
> why Catalonia wants to separate from Spain?

I won't actually answer the question (it's complex, and others have done so already). I just want to make sure people understand that we don't really know what "Catalonia" wants because no real referendum has taken place.

Catalonia is a heterogeneous society that has attracted lots of immigration from poorer regions of Spain over the last decades, and claiming that "Catalans" want independence without doubt can only be done by adopting a dangerously ethnocentric meaning of "Catalan".

If you look at regional elections, separatist parties have consistently achieved less than 50% of the votes, even when posed as "plesbicitary" [1] on the issue. They've only managed to form governments because, as it's often the case, the electoral system over-represents rural areas.

> What prevents this centralized body from making politically motivated decisions?

An established institutional culture of apolitical service, reinforced by respect for those who uphold it and consequences for those who violate it. The kind of thing that the U.S. still expects of its military, judiciary and public service, and the kind of thing that is corroded by political leaders showing contempt for it.
There's no way there's a world where everyone who needs to be in Europe next week from, say, New England, heads down to Boston to queue up for a utilitarian passenger ship that takes a week to cross the open ocean. How many people would you need to even justify the cost and environmental impact of moving such a ship? 300? 3,000?

Cargo ships have thousands of containers on them (massive scale) and they move relatively slowly. This is not a reasonable comparison. You can't just pluck weight per-mile cost out of the air and apply it to passenger travel.

Your loop body looks incorrect. You're both adding 1 when updating low and subtracting 1 when updating high -- but you let the high index start at array.length. It's possible that your additional || clause before the high update mitigates the effects of this, but it's at best inefficient. To implement binary search effectively, it's useful to think about invariants. https://zhu45.org/posts/2018/Jan/12/how-to-write-binary-sear... looks like a decent post on this topic. Searching for "binary search loop invariant" or similar will find many similar articles. I recommend giving them a look, it's a useful thought framework for this algorithm :)

They’re paid a pittance. They can’t build up any savings.
Those problems are solvable. If they focus on them all now they can get there.

There are several companies in the world making good rolling stock. There is a fairly long leadtime, which means they better be making orders today to get the rolling stock they need in time. Good rolling stock is of course a requirement to increase passenger count.

Infrastructure can be built and rebuilt. The know how exists in the world, it just needs money and a bit of time (the more money the less time)

These two need to start today. However some smart planning and priorities the places where the most gains can be had. Doubling ridership in a small but busy section is often easier than doing the whole system and can add up to 35% overall increases even though the rest of the system is slightly down. This could be doable in 10 years. (then you focus on the next small part of the system and bring that up, while continuing to keep service high on the first, and soon your network is useful)

People can be hired and trained. The right people will make it work. That is management, and maintenance, and operations.

They have 8 years to do the above: it typically takes 2 years for riders to respond to better service once it exists. It is a hard problem for sure, but if they have the money and will it can be done. That is a rather large if though, and I don't know if they do)
> The most basic kind of truths are facts.

Except for that for a lot of "facts", according to Rousseau, we already have 4 truths: what you say, what I say, what we agree upon and what really happened.

So, while the pursuit of truth is important, I'd argue that respect towards each other even when we cannot agree is the most important thing.
