I was contemplating the impact of semiconductor technology over the last 30-40 years, and I don’t think any other advance has had this kind of impact in recent history, and it has to rank up with any of the big advances. (I’m thinking mainly of computers and various displays, but it goes beyond that. Lasers, too) And the impact is not just in straight productivity, it’s also tied in to the fact that the tech is deflationary. A basic personal computer costs about the same today as it did 30-40 years ago, when they started to become ubiquitous, while the capability of them (processing power and memory) If the cost of computing power had risen with inflation or even just been flat, computers would be massively more expensive than they are now, and without that you don’t get the same productivity improvements that we’ve seen. Printing might be one example that rivals the productivity gains but I’m not sure of how the costs scaled as printing advanced. Comments?

~18 min video in the link https://laughingsquid.com/trebuchet-history/ On July 24, 1304 King Edward I of England captured the last stronghold of resistance against English rule in Scotland, the formidable Stirling Castle. But he did not have to storm the castle to make the defenders surrender. He merely had to threaten them with perhaps the most terrifying siege engine in the era… I built a model trebuchet years ago, the arm perhaps a foot long, which I would demonstrate to some visitors to the lab

Scientists tend to be skeptical of numbers presented without reference, and anecdotes presented without systematic study. The religious, and crackpots, and people who don’t understand probability and statistics (these groups have overlap), can find great meaning in them

“Because” is the problem here. If you want to assign a causal relationship you need to obtain actual scientific evidence with a systematic study, and show that it’s not something that happens randomly. Correlation is not causality, and confirmation bias does not even show correlation.

Narratives that tell you how to sort out the way to think about QM are called interpretations. Actual QM, or any competing theory, would be able to make specific predictions. There’s no actual science here. To your question in the title, this belongs in speculations. There is religion here, but it’s what you invoked, no in QM. Anecdotes are not evidence. Coincidences happen all the time.

He can’t legitimately offer something that’s not his.(applies to an open strait of Hormuz, too) Trump’s promises aren’t worth anything anyway. In any event, he’s not going to stand up to Russia. $200 oil is good for Putin (or would be if Ukraine weren’t blowing up Russian tankers and refineries), so that’s not really a threat. Putin is giving Iran satellite intelligence, because that conflict is helping him.

“We take full responsibility for the confusion and misrepresentation it caused for attendees, including our African partners.” I’m surprised they didn’t blame Biden

I think you can assign the status to a community, if they don’t have access and it’s not by choice. But that does raise an issue - what we consider aspects of poverty (in the US at least) have changed because of access to “modern” conveniences like refrigeration and indoor plumbing. Seems to me a lot of these are tied to health outcomes. You can be content with your life, but not having e.g. reliable access to clean water is IMO a sign of being impoverished

I will note that there was a request to explain this, and you have still not done so.

There’s an attitude of having money meaning you can do whatever you want, i.e. responsibility is for other people (which has become more rampant in the US with Trump being in charge and participating) so why do what’s best for all? You can just buy a few politicians, which is the cheaper option.

Good point; I recall some discussions from long ago where being poor was conflated with being destitute, and I disagree with that I think poverty is not having basic needs met - food, clothing, shelter, basic healthcare, etc. but it can also be viewed as a severe restriction of choice/options, i.e. being kept from doing basic things because you lack the means. Where you live, what you eat, whether to seek medical treatment, etc. because of the means at your disposal. No, it’s not, but if you have wealth you generally have more options regarding your well-being, so anything having a negative impact on it is more likely to be from choices made rather than being forced upon you, so I think there’s a correlation.

You were asked about a mention of “ironic” before; I find this to be ironic, given your pattern of not answering requests for clarification when you make a comment. You engage in evasion and sometimes a strategy of “a good offense is the best defense” as it appears you are doing here. Also the farce of pretending you didn’t downvote posts when you did. They are anonymous up until the point where you engage in a charade like this. If you can’t post in good faith, don’t post at all.

Primarily because that was not the question that was asked, making this off-topic, and you’re posting to advertise your speculation, which is against the rules.

The reading from the one on the left depends on the value of g; it measures weight. The compression of the spring is from a force. The one on the right does not - any value of g will do. It measures mass. The value of g cancels, since it’s affecting both sides.

I think most poor people know how hard they work, so they might not succumb to the propaganda that poor are in that situation because they are lazy, which removes a barrier to helping others, if they can. One of the insidious behaviors we have in the US is a willingness to deny help, if it means people we hate are hurt. A certain swath of people can’t stand the thought of one undeserving person (in their view) getting help. The right has made an industry out of pointing out the anomalies and offering them up as typical to undermine social programs that help people, sowing the notion that people are getting away with something and ripping us off. (of course this doesn’t extend to tax cheats for some reason)

They threaten this, but rarely follow through. In the US, at least, states/regions that have started taxing the rich have not seen the threatened mass exodus. There are reasons the rich live/do business where they do separate from taxes. I mentioned this but if this in response to my post, the mention was only as a recognition that this happens and not an endorsement. I think religion tries to get people to help others, often in spite of themselves. It may be that certain proponents of the various religions recognized that society would be better off as a result and that this runs against the natural instincts of many.

A more generic category of power might cover this and other things (e.g. heat)

Basic human nature is to be selfish to some degree and to have some fear of things that are different (again, to some degree), i.e. a tribalistic attitude. Depending on where you are on that scale you will be more or less altruistic, and in any case, many are more likely to help someone they know rather than a complete stranger, and more likely to help in the case of a disaster rather than the mundane problems like poverty and hunger. It doesn’t help that there are those who exploit our emotions to try and paint people as deserving to be poor (they’re lazy) or not worthy of help (they’re minorities - you’re better than them)

Apparently not his first alias. He previously enlisted under the name John Hume Ross, according to his Wikipedia article. I had no idea.

And I’ve been asking, as I’ve done elsewhere, for analysis that doesn’t depend on a specific technology. The energy constraints on e.g. visiting a planet, has certain parameters that don’t depend on technology. Propulsion has some constraints that don’t (I presented one) and others that would eliminate or constrain certain classes of technologies (chemical reactions for propulsion, for example) What we’re left with is a circular argument for visits of the type described in the OP. You’d need new physics to explain them (e.g. a reactionless drive, since we never seem to see effects of a reaction mass) but without confirming such new physics, simple observation is not evidence of visitation. You’d need physical artifacts — something left behind — that could independently confirm that sightings.

There should be no offsides once the ball is as deep as the penalty area box line that’s parallel to the end line, or on free kicks in the attacking end. Once the ball leaves that zone you reset (similar to hockey blue line/offsides, AFAIK)

I read Deborah Blum’s The Poison Squad (about the efforts to get food safety regulation in place in the US) when it came out and subsequently realized that the tactics haven’t changed. Big business will use any and all legal tactics to protect their profits and shield themselves from blame/responsibility for doing harm by selling us unhealthy (often deliberately unhealthy) food Self-regulation is a myth. Too many bad actors are out there who only care about profits. We see these days that bribery is part of the repertoire, too

No. Matter enters and leaves. Literally tons of space dust enters the earth’s atmosphere every day https://www.universetoday.com/articles/getting-a-handle-on-how-much-cosmic-dust-hits-earth But you said introduction of energy, and the relevant term would be isolated system, and it’s definitely not that.
