Just a lay person here. I would say, that that "potential energy" is not really energy, at least not in the sense of "the energy is inside this object" or "this object has so-and-so much energy". I would say you move an object into a different environment and the environment is all that is needed to make the object act in a certain way. If that environment is a heavier planet, then it means, that the object will behave differently than on Earth. The energy you spent to bring the object away from Earth if you want, is stored in the fact, that this object is now in a different environment than before you spent that energy. If the object were to return to its place, it would make use of energy the other way around.

Looking at the object alone, you cannot see any of that energy, because it is not really in there, but stored in the fact, that this object is in a different environment. That is what gives it potential.
Well actually, we started selling that off to SNC and it's rotting now..

CO2 emissions per capita in the United Arab Emirates are equivalent to 23.37 tons per person, one of the few countries with higher per capita emissions than the USA.

This is including the massive (60-70%) low-paid immigrant worker population that I assume doesn't have a significant foodprint compared to the Emiratis and Western expats living there.

Those "martian" cities will be needed as giant shelters on Earth before we can build them on Mars.
Awesome - Didn't know about this trick. I'm reconfiguring most of the my extensions to this.

Gracias!
The question is: Where is the energy stored in the meantime? Where does the extra energy, if the ship falls into a heavier planet, come from?

From a classical physics perspective everything that has mass is immersed in the gravitational field of everything else, it's just that most of that potential energy turns into kinetic energy only when you get very close to something.

Basically your potential energy is this mind-bogglingly large number which would only approach zero if the whole universe were condensed into a single point.
(I'm an engineer at Amazon, but I don't speak on behalf of the company, I'm just sharing my experience)

Here are a few different ways that AWS and Retail interact:

1. The obvious that everyone knows: Retail uses AWS's products, providing feedback and ideas for new services and features.

2. Employee transfers: it's quite common for people to move between Retail and AWS and vice versa, and they bring what they learned in one org to their new org, helping to spread information about best practices.

3. Other employee knowledge transfers: I've personally benefited from engineers in AWS sharing their knowledge about general engineering topics on internal interest mailing lists or through tech talks.

4. Best practices: there are some differences, but AWS and Retail operate similarly in many ways: use of 6-pagers for sharing ideas (https://www.linkedin.com/pulse/beauty-amazons-6-pager-brad-p...), weekly review of metrics, hiring tools and practices being just a few examples.
I wish everywhere was like that, but anecdotally my midwest suburb experience or would-be experience is very different. The only places that have chargers are ~3 grocery stores all 15+ minutes away. Work is a surface lot nowhere near any electricity, let alone a charger. And the garage circuit in my rental house isn't even rated to support 120V charging. Being able to comfortably get an EV will either take years, or a complete change in scenery. :(

Does that stat include all the "expats" in UAE? I mean, only a tiny percentage of the people in UAE count as citizens (a problem in its own right, but ok), so if that was used as the denominator then it's not a very worrying statistic.
There's more nuance to it but those are the basics.

Disclaimer: I am jewish, and found that accusation offensive.

After Trump took office, I began reading The Rise and Fall of the Third Reich, to be on guard – I was afraid. The ICE camps are evil, scary, cruel, and probably illegal, but not indicative of the sort of fascism we saw under the Nazis. After all, they functioned similarly under the previous US president, who did not seem to have fascist tendencies. As others have mentioned, the detainment of the Uighurs rings much, much closer to Nazi Germany. In some ways scarier.

We have the freedom to leave work and sit in front of courthouses in protest until those responsible for ICE atrocities are prosecuted. We have other similar such freedoms.

Demanding your employer to take a foolhardy action which will register as a minor inconvenience in the target's IT department is... just silly. It's grasping at the closest power center you can find instead of making the effort to find a relevant one.

I have a hard time understanding the logic here. GPAs are essentially useless, so what else do we have to go off of? "Hollistic admissions" processes seem to be even more skewed towards rich kids, as they have far greater opportunities outside of the class room to pad their resumes in exactly the way that colleges look for. This seems entirely backwards to me.

If there is a systemic bias in test scores, it is still better to have the test score there so you can quantify it, and adjust your admissions policy to account for it. By throwing out the test entirely you are flying blind.
About 10 years ago I knew a guy who had to turn down an amazing opportunity at another company because one of his kids had a pre-existing condition. This boggled the minds of us non-Americans where healthcare is not linked to your employer.

Eh, this kind of "the sky is falling" argument doesn't hold much water to me. So, some "smart nonconformist kid" doesn't get into Harvard. Is that the end of the world? Larry Page went to Michigan, Brin to Maryland - they did fine. There are a lot of great public schools out there. Talented people like that aren't getting locked out of anything.

A much bigger problem in education starts much earlier. If your parents don't provide a stable and education-leaning home life, or you live in a school district where safety is a bigger concern than educational quality, well, social mobility becomes a lot harder then. These are some hard problems, but reach way beyond education, into the social safety net and beyond. Guaranteeing that a bright kid who is not born into the best circumstances gets a fair shot at life is still a work in progress, but has little to do with whether they get into Harvard or MIT.

I think we should just roll some kind of standardized test into your Junior year. Instead of it being this external expensive thing, everyone who wants to go to college can just take a half year preparation course in your Junior year and take the test at the end. We don't need this to be external. We already do a lot of standardized tests to measure student performance. This fixes the GPA problem between schools and the uncomparability of those numbers.

I want to know why implementing this isn't a national debate in US, it seems like such an obviously good idea.
It can be if you want it to. At Harvard, there's very few requirements on what courses constitute a degree, so if you want to get a degree by just taking the easiest classes possible, you can definitely do that. Of course, most students don't do that since that's not why they went there. I do think professors try to give higher grade averages for the harder classes to avoid punishing students for challenging themselves, but I don't really have a problem with that (if you chose those classes you're probably not in it for the grades anyway). Also, at least I'm the sciences, a good fraction of students start taking classes at the graduate level either freshman or sophomore year, since they'll have completed a good chunk of the undergrad curriculum in high school.
Imagine some kind of alien life form that arose and evolved in intergalactic space. They evolve intelligence and start developing physics. Their physics knows about electromagnetism and maybe the strong and weak nuclear forces, but they have never seen any sufficient concentrations of mass to notice gravity.

They would still know about mass but for them it would just be a property of matter that determines how strongly it reacts to force.

Their model of how force works would be that for each kind of force there is some kind of charge. How much of that kind of force you have between two bodies is determined by how much of that kind of charge each has and how far apart they are.

How each body responds to that force is determined by its mass.

Mass and charge are independent for all of their known forces. You can have two bodies with the same mass but different charge for a given kind force, or two bodies with the same charge for that force but different mass.

Eventually they would discover gravity and I think it would immediately stand out as fundamentally different from the other forces because its charge is not independent of mass. You double the gravitational charge on a body you also double its mass. You double its mass you also double its gravitational charge.
We haven't observed the graviton, but it's something theorists routinely discuss. Basically, any quantum theory of gravity that reduces to general relativity in its classical limit will pass through a semi-classical regime where it's well-approximated by gravitons.

I'm familiar with your (1) and I think it fits extremely well with the negative emotion explanation.

At least for me, making a difficult decision that might have far-reaching consequences can be very uncomfortable if I don't have all the information. And it can be very easy to procrastinate because I tell myself that more information might be available in the future (even when that is clearly not true).

So, it's not so much that I search for an optimal strategy and more that I know there isn't one and I don't want to bite the bullet yet and make a decision.

Social Distancing Puzzle at the Bar
lower, upper and numbers = 62 options | wordlist = 10 000 options:

62^12 = 1e21
10 000^5 = 1e20

The problem is you not using a word generator and instead relying in your invention, most of the people will use top 5000 words (5000^5 = 1e18), imagine you can even lock one of the words (a color maybe?).

So this way of thinking might be good if you know what you are doing and use uppers and lowers and symbols, if not, it is actually a bad advice.

"Technically"? This isn't merely a technical point. HTML is an open standard, and Flash isn't and never was. Flash also never "opened up the web"; it opened up a proprietary way to do programming and avoid actually using the Web.

As an aside, Flash is also extraordinarily inefficient and a plague security-wise, and always has been. Steve Jobs pointed this out a decade ago, of course.

Meanwhile, HTML continues to have none of those problems.
Also, the study being retracted does not mean it does not cause harm. It just means we don’t have evidence for that at the moment.

On a side note: a product is always a 2 party deal, and needs to be win/win.

For example increasing the price is always anti-consumer, but it might be part of the deal.

So I don't like to look at products from the perspective of 1 party, since it is always a negotiation between 2 parties where both end up with a win.
How else are you going to keep the Asians out?
What exactly are you talking about?
Here's my lay person thinking on this. By lifting objects up or down, you're altering the gravity wells of each object. A spaceship leaving Earth would make Earth's well a bit smaller.

The question you pose makes me think the following: if it requires no energy to fall down a gravity well, but you can use that falling to generate energy (hydroelectric dam for example), then where does that energy come from?

So this makes me think that as the following:

1. Increasing gravity wells (object falling) creates energy debt to the well (the debt is larger), in exchange for harnessed energy by things like hydroelectric dams.

2. Decreasing gravity wells (object being lifted) pays off the energy debt from the well by you using energy in the lifting action.

So for me, there's no energy stored, it's just a debt in the form of the size of a gravity well.

Words of warning from a not so young (36) chronic procrastinator with a rather messed up life: Take it seriously. I'm not talking about reading HN in your 7th work hour when doing stupid Excel sheets. I'm talking about messing up years and years of your life. I believe it's a symptom of some deeper issues and it won't go away from alone. Lack of sleep, stress, work overload, information overload amplify the effects but once it crept into your life outside of work it really can wreak havoc. Simple things start to become complicated and you are in a constant negative feedback loop. The worst is that you procrastinate not only work but rather your own existence because you'll constantly attempt to catch up but just can't.

At the moment doing pomodoro and putting everything in kanban charts and devide&conquer seem to work somewhat. I don't really have any clever advice beyond that, it just sucks.
We spend a lot as well, it's just we pay it in taxes and the government pays the $13,300 per household. In some provinces you also have to pay monthly for a medical plan. It's cheaper than the US system but it's also not as good because there are waiting lists for most things and people die on those lists. The cancer may have been treatable when the person was added to the list, but cancer doesn't wait for anybody. What it is is fair though, available to all regardless of if they're working or not.

It's likely my mother would have died, for different shortcomings of the medical system if she had still lived in Canada. Fortunately she's in the developing world now and received affordable, correct, and timely care.
