I am a fan of raising weights for potential energy. There are no storage losses and requires less space than water. Just wish I could find how it compares to other storage methods for energy loss during reuse.

I wonder how Sweden made the list. I have always been under the impression that all of the Scandinavian countries were more egalitarian than most of the rest of the world

Not sure what is being pointed out here. The first number is even, so obviously not a prime number, and they are already smallest to largest using standard method of reading (L to R & top to bottom). Are you saying they are all semiprime or something else?

True, but if they "felt endangered" by any of the people they shot, it seems to me they would have either used a lot of deadly force or fled the scene at the capitol.

Can you imagine how many people would have been killed and injured during the January 6, 2021 attack on the capitol if the same tactics were used? Some of those people actually were armed and attacking police doing their jobs, unlike anyone in Minnesota.

Ya, but in the minds of many (if not most) people outside the USSR, soviet=red, even though they probably have no idea what a soviet is.

There, fixed it for you. If they hadn't misspelled it everyone would understand.

My political positions all get 100% approval.........from me. Seriously tho, imo, the political elite are those who can afford the time and money to be involved in politics, especially when talking about positions beyond local governance.

The problem is, look how many treaties and agreements our President has unilaterally changed without notice, even ones he had negotiated (think trade agreements with Mexico and Canada). The speech in Davos to some of the most prominent people in the world was identical to the ones he gives to yokels in rural America; the election (2020 but not 2024) was stolen, US gets nothing out of NATO, immigrants are destroying the fabric of society, US is "entitled" to Greenland and Canada would be better off as a state, "sleepy Joe Biden was the cause of everyone's problems and I've solved them all, I've solved 8 wars and should have gotten a Nobel prize, etc, etc. for a solid hour. Really happy it was just background noise while doing something actually useful. I couldn't imagine having to sit there and seem to pay attention, he reminded me of Biden during the debate that caused the latter's exit from the race.

Just one question Mr President. How will we know when America is great again?

In the state of Pennsylvania, AFAIK all of the electric utilities make a profit with typical return on equity rarely going below 5% and often near 10% or above. All rate hikes have to be rubber stamped looked into and approved by the Public Utilities Commission with a period for public comment before approval. Sometimes the increase is less than requested or one is put on hold for other reasons but I can never recall a decrease or outright rejection of a hike, though it probably has happened.

Surely you aren't talking about monopole magnets that don't exist? In any case the strongest part of any magnet I am familiar with is always the poles. These guys xxxxxxx sell magnets but their site answers a lot of questions in a fairly concise manner

I watch Washington Journal on C-Span almost every day and it is pretty unbelievable how many people are and have been supporting everything going on with Venezuela and believe that it has anything to do with drugs. Even if it did, none of those killed would have received the death penalty from any conviction over their activities. Furthermore, when the Coast Guard does interdiction for drugs (with presumably the same intelligence sources as Trump) about a quarter of the time no drugs are found but many seem to regard any possibly innocent people killed as just "collateral damage". It's a shame none of those saying that are Christians......oh, wait many supposedly are.

More mass always = more gravity. Unless you are adding mass from somewhere, that quantity (and its gravitational effects) will remain constant regardless of the density, which only relates to the volume that mass occupies.

I expect it will end up with Monsanto paying into a fund similar to what happened with Johns-Manville and the asbestos settlement. BTW Johns-Manville is still in business all these 30+ years later after filing for bankruptcy because of that settlement.

Ya, I'm pretty sure your compressor is operating normally, so far as oil is concerned. You really can't tell what the level actually is in that kind of compressor unless it is shut down.

Unfortunately, those "bugs" live in a pretty specific environment and it takes a year to break down the softest plastics and over 3 years for harder ones. However, it may be possible to adapt Ideonella Sakaiensis to a wider habitat and even that speed is still way faster than UV light and other natural processes break down plastics.

The 3 times I ever did "survival" was a very long time ago, twice as a Boy Scout and once for an outward bound program at school. Each of us was allowed a knife, fire starter and canteen of water for the three (Boy Scouts) or seven (outward bound) day sessions. Being such a short period of time kind of skews things because one could easily survive, even for a week, with no food and minimal water, so there isn't as much pressure on success. Having said that, I am pretty confident that I could survive for quite a long while anywhere in North America where there is potable water, especially if I can take an array of tools with me. The trick is knowledge of local flora and fauna combined with survival skills, especially fire-starting and shelter building. As a teenager with not much better to do, it was kind of fun and very informative but I haven't felt any overwhelming urge to do it again in the half century since.

One of the problems with this discussion is that "freedom" is a pretty ill-defined term, dependent on subjective interpretations. As pointed out by Phi, my "freedom" to own a gun impinges on others' "freedom" to feel secure. So which is free? The whole point of living in society is to give up some freedom to do a few things in exchange for the freedom to pursue other interests. I don't think it is just coincidence that the most organized (generally those with the most laws) societies are also the most technologically advanced, something that contributes greatly to my "freedom". Because of this abstract thing known as "money" (which is really only a representation of other things) I have to follow a bunch of rules to live in a society that uses it. However, it also makes me free to do things besides provide for my basic needs, or even have to be much concerned about them. I have done survival expeditions for up to a week and being comfortable is no trivial matter, even if you don't need a fire. EVERYONE loses weight on these outings because of decreased calorie intake and increased physical activity and is unsustainable over time. If you ever saw the tv show "Naked and Afraid", very few of the participants who actually even make it to the end of their allotted time there (usually 20 days) are doing any more than "limping across the finish" and would not likely survive long term and they are people who supposedly have some survival skills beforehand. Personally, I am fairly confident in my survival skills but feel a lot freer not having to use them and kicking back to read "The Great Monkey Trial" at night or looking at sunspots through a telescope at the Franklin Institute while on a bus trip to Philadelphia. I guess to sum up, I feel freer having more choices. Living in a society facilitates that, whereas an individual has little freedom other than how to provide for their basic needs.

That may well be how the pump is designed but without knowing the manufacturer it is hard to be sure. In many air compressors, the oil also provides a seal to get better pressure. If the oil level returns to normal after shutting things down and the compressor doesn't make unusual noises (all compressors I have ever seen are loud but listen for clanging or severe vibration) or emit a burning oil (or metal) odor, I wouldn't worry about it. I would, however, make sure to check the oil level every time I used the machine.

Sure, but in reality zero isn't quite the same as nothing in maths, just the best way we have of describing and using a null quantity for comparison, according to my understanding of it.

I realize I'm a bit late on this conversation but isn't "count" being compared to nothing (i.e. zero)?

This is the gist of the problem with thinking energy is gained and is the reason you are able to slide across the floor an object too heavy to lift.

Possibly, but there doesn't seem to be much uproar about cameras being on virtually every block of US cities or cell phones being able to track everywhere one has been with it.

I don't disagree with any of this. One thing is, most new vehicles have cameras so I don't see why automated vehicles shouldn't have a recorded 360 view to determine such things.
