There's nothing arrogant about pointing out that over unity or perpetual motion machines won't work. It's just an extraordinarily well-established fact. Nothing to do with "professional reputations", more likely simply not wanting to engage a person they may have decided is a crank. It is likely that nobody can be bothered to go through all the mechanics of forces when the outcome can be shown far more simply by considering energy. As I believe I may have pointed out back at the start of this thread, considering energy is sometimes a useful way to simplify the analysis of problems in mechanics. I don't know what you are hoping your machine will do, but what is guaranteed is you won't get out more work than you put in.

Yes, insensitive of the photographer. Even in western countries it is polite to ask permission, let alone in traditional muslim societies.

I know a woman of Scots ancestry with green eyes. I once went out with a girl who had dark hair and grey eyes, who had part-Irish ancestry. Yesterday at the greengrocery stall I met an Irish girl with red hair and blue eyes. These unusual combinations do seem, anecdotally at least, to crop up in the Celtic nations. But it may all be a bit of a myth. After all, I understand the term "Celt" is pretty meaningless in terms of biological heredity, and is more of a cultural term.

A Treatise on the Existance of Santa Clause
exchemist replied to YeahScience's topic in Speculations
“Another” science expert? 😆 -
Conflating Jews with Israelis is an old trick of apologists for Israeli policy. I also note Godwin's Law is in operation. The war the IDF is operating in Gaza certainly looks a great deal like ethnic cleansing. - They have herded almost the whole population up against the border with Egypt, in the hope the Egyptians will let them in, having killed over 30,000 of them. - They have tried to get the humanitarian operations of UNWRA stopped, by various means, including disinformation to smear it with complicity in the 7th Oct massacre. - While this is going on, Israeli settlers have been given free rein to take over more land. - There has been silence from the Israeli government about how Gaza should be governed once hostilities cease. - And, far from getting serious about peace negotiations, Israel has actually assassinated the chief negotiator on the other side. So it is a fair inference that Israel seems to want the war to go on until the Palestinians in Gaza either give up and leave, or die.

Suggest reading the thread and addressing the issues raised, specifically the issues of how to make reproducible observations, the degree of confirmed predictive success of the theories, and the use of theories such as Freud’s, which seem to have only shaky empirical support.

Looks like a really impressive piece of cyber warfare, targetting only the fighters equipped with pagers and simultaneously injuring them, knocking out their comms and sowing panic. Very clever. Just wish the bloody IDF would be more targetted in Gaza. But since ethnic cleansing seems to be the unstated aim there, not much hope of that.

If one is a fool, yes. Asking such a question would indicate failure to understand, or to address, why this question is asked of psychology, specifically.

Yes, I think that's the point: the more the idea conflicts with what everyone else considers obvious, the more it becomes inescapable to allege a conspiracy, in order to account for why everyone else is supposedly wrong. This is true of flat earth, 911, Kennedy's assassination, Princess Diana's death (white Fiat Uno/Duke of Edinburgh etc), moon landings, Covid and 5G antennae............ @Night FM, perhaps it would help if you could give an example of a contrarian belief that people call a conspiracy theory but which does not imply a conspiracy. Flat earth is a poor example, for the reasons outlined.

The vacuum energy v. Higgs field - discrepancy
exchemist replied to chron44's topic in Quantum Theory
What do you mean by the "volume" of a particle? Such a concept requires objects with sharply defined edges, doesn't it? -
They are motivated by profit, but what @CharonY says about shelf life, specifically, has the ring of truth. I worked in the lubricants industry, in which we had to quote shelf lives for packaged lubricants: engine and gear oils and so forth. When a new product is developed, you can’t wait for 5 - 10 years or more before putting it on the market, just so you can determine when it may start to go off. Also, so much depends on storage conditions: temperature, moisture exposure etc. So what a manufacturer - any manufacturer, I suspect - does is come up with a safe “use by” date from the data on life they already have. As it will be an estimate, they will have to err on the conservative side for obvious legal reasons. No need to ascribe malign motives: it’s a purely practical matter, faced by any manufacturer.

The extract you quote seems to be pretty badly written and to be rather a muddle. They criticise science for not accounting for "the subjective experience of life", without clarifying who or what is doing the "experiencing". One might assume they are talking about human experience, but in the next sentence they speak of failing to understand "the various aspects associated with the [sic] biological entities". So actually, they seem to have in mind all organisms, not just human beings. So what, in that case, can they mean by the "subjective experience" in the preceding sentence? Are they suggesting all life, including, say, that of a wasp or a plant, involves some subjective experience that it ought to be the job of science to explain? It seems to me they need to start by justifying the assumption they seem to be making that there has to be some special "subjective experience" that is a universal special feature of living organisms. So that is the first point. The second is that you now seem to be confusing the study of subjective experience, e.g. as recommended by these authors, with a supposed need for science itself to become subjective in its methodology. That would be the kiss of death for science, obviously.

Why do you think fidelity between sexual partners is valued?

You may get the odd one, but the fact remains it is far harder to bring off than shooting a mass of people with a gun if you feel pissed off. This is why school shootings are virtually exclusively an American phenomenon. In the UK we had the last one in Dunblane in 1996, when someone was able to get hold of....a GUN.....:https://www.businessinsider.com/uk-changed-laws-ended-school-shootings-after-1996-dunblane-massacre-2022-5?op=1 There will be just the same adolescent alienation and resentments occurring all over the world, but without easy access to guns, people don't find it is easy to act on these destructive impulses - and the moment usually passes without serious incident. I'm afraid I now laugh whenever yet another school shooting is reported in the USA. They will go on and on until guns are properly controlled, as they are in other civilised nations. Yet we see Americans contorting themselves and jumping through all manner of logical hoops to avoid the reason that is staring them in the face: the availability of GUNS.

Is science useless if it doesn't aid people in procreating?
exchemist replied to Night FM's topic in General Philosophy
In other words, you've made it up. I thought as much. I note that you are already shifting the goalposts: from procreation to sex and procreation. That already makes a significant difference, of course. Anyway, since you've posted this in Philosophy, I would simply draw your attention to the distinction between what the biology of the human species as a whole may optimise itself for, and what purpose an individual human being may seek or find in the course of his or her life. I suggest clarifying which of the two you want to talk about. -
That's exactly the thought that sprang to my mind. Well, one of two actually. The other was that, when I was a kid, my brothers and I developed the idea that Mr Waverley, the boss in The Man from UNCLE, had his lungs in his buttocks and breathed by shifting from one buttock to the other while seated. Don't ask me why. One of us just thought it would be an amusing thing to keep in mind while watching the show. So I did allow myself a chuckle at the idea someone might breathe through his arse.

Aunt Sally Alert: Who has ever suggested the only purpose of life is procreation? -
This illustrates what I suspected: you are confusing lack of precision with lack of objectivity. The Mohs scale has limited precision, since all it can do is rank minerals relative to one another rather than provide a quantitative value. But that does not make it subjective. 2 independent testers will agree on the relative rankings to assign to a group of minerals. (In fact the writer of the blog you quote is rather mis-applying the Mohs scale, since it was never designed for alloys such as steel. It can only be expected to give reliable results for pure substances.)

Quite. What would be the motive? The trip would take thousands of years - and the same to get back again, if return were envisaged, greatly exceeding the lifespan of any conceivable carbon-based life form. Sending a robotic probe might be more effective, as it could be accelerated harder and could beam signals back at c. But even that would be a very long term project, spanning generations. The best method, almost certainly, would be by remote sensing, using good telescopes, spectrometers etc. And why would our planet be of any special interest?

OK, I'll wait for you to find them and present before commenting further, as I suspect you have misinterpreted something about them, whatever they are.

What findings, then, posted where? You have posted 25 pages of posts. I cannot be expected to trawl through all of them in the hope of identifying what you are talking about.

I don't rule out microbial mats for the greenish colour in the foreground of the picture. It is the pale, bluish grey colour that I find interesting, as it seems unusual. There is no tourism office on the peninsula, though I suppose there might be in Helensburgh. When I next go back, I might see if Glasgow University has anything, or anyone, to comment on this. The Dalradian Series is pretty famous (if fiendishly complicated) and well-studied, so I'm sure the answer is there somewhere in the geology community.
