Given that, it appears to me that the article says nothing new. Experiments have already 'confirmed' Bell's Theorem, which says that one of QM, locali...

I haven't read the paper yet, but I did a search for references to it on physicsforums and found nothing, including in more than one recent discussion...

I think the Copenhagen interpretation is not compatible with the usual folk notion of 'objective reality'. It denies that there is any fact of the mat...

What troubles me about this is that, on my understanding of QM, wave function collapse is non-measurable. It is a matter of interpretation, of ontolog...

Is that what the paper does - create a situation where both observers have the same level of detail in their knowledge, and the details contradict eac...

I don't believe in objective reality so this is a bit moot for me. But I'm very interested in QM so I feel the need to comment. I think it's overstati...

It's not at all like that. Your example is of a weak justification to not do something. Not doing something is consistent with the notion of laziness....

I'm on the side of those that deny that religious belief is necessarily irrational, in this discussion. But I have a viscerally negative reaction to s...

Let's review your argument: You put forward as one of the reasons why you are opposed to social pressure against certain types of speech, that you are...

So?

Under that definition, a group of Amish collaborating to raise a barn is an instance of mob mentality. It's what most people call 'cooperation'. Being...

1, 2 and 4 are consistent with the conclusion. It sounds like you are a libertarian. Fair enough - it's just a different ethical system. 3 and 5 are n...

I am curious to hear about how you come to that view. Is it derived from some set of moral principles, or is it more just a feeling? If principles, I'...

Nice work. That is a sentence that's easy to respond to. Is there something wrong with applying social pressure against somebody's expression? Well, a...

'Real joy' sounds a bit like a 'true scotsman'. I think both un's and your descriptions fit within the generally understood concept of joy.

I don't want to try to control your expression, but I feel obliged to point out that asking questions with such fundamental grammatical errors that th...

Baby boomers being fooled is a pity. Fortunately, as St Roger of Daltrey prophesied in 1971, we won't be fooled again!

Excellent, well-researched post. Thank you.

One person's political correctness is another's basic good manners. You will need to be more specific about what form of political correctness you obj...

It turns out the thread is actually about a completely different problem. The title is a misnomer.

Here you go: P1: ?x(Fx ? ?y(Fy ? y=x) ) P2: ?x(Gx ? ?y(Gy ? y=x) ) P3: ?x¬(Fx ? Gx ) C1: ?x?y We write ‘a’ for an object that satisfies P1 and ‘b’ for...

Yes that sounds good. I have started a thread asking for recommendations.

It's a good question, often asked and unfortunately one for which I do not have an answer, as I did not use textbooks in learning logic. It would be g...

Very roughly, a formal language is (1) a set of symbols that can be used, together with (2) a set of rules for how they can be strung together to make...

First let me write it out in a way that's a bit easier to read - for me at least: "If exactly one object has property F and exactly one object has pro...

Look up any logic text. There is no shame in not knowing the difference between a theory and a language. Most people don't. But it is inappropriate to...

No they are theories, expressed in the language of mathematics. The distinction is critical.

I usually use \to for \to rather than \Rightarrow because it is quicker to write, and more commonly used in logic texts. It's worth noting that changi...

A Tautology is a feature of a language, not a theory. Peano arithmetic is a theory, so something being true in Peano arithmetic does not make it a tau...

The statement of "1+1=2" in Peano arithmetic is: S0 + S0 = SS0 Because "1" means S0 and "2" means SS0. S is the 'successor' function. That is not a ta...

This discussion was merged into It is life itself that we can all unite against

Objects move through space, not through space-time. To move through space-time would require an additional time dimension with respect to which that m...

I don't believe in utopian visions. We are not heading towards heaven on Earth. But I do think that things have been getting generally better in the W...

The only way I could imagine him being correct is if nobody can ever be happy, even for a moment. Since that would require that everybody that has eve...

:smile: Yes it's amazing how destructive and disloyal to their country some politicians can be when trying to win power. We have that here at the mome...

For what it feels like, you'd have to ask the people that are having children now. My youngest is aged nineteen, so I can't remember. For where it spr...

It can't do that because nobody has that understanding. We all know that the urge to procreate is far too strong for a movement against it to ever be ...

In mathematics a statement that contains an equals sign can be an identity or an equation. An identity holds true for all possible values of the pronu...

As the article and my post make quite clear, they used it to attack the then-government (Labour) in an attempt to make them lose the upcoming election...

The figures may or may not be accurate. We don't know. But we do know that the sources are anything but impartial. The two sources listed in the footn...

You wrote the following in response to my saying that your direct reply to my question about a ratio in the post to which I was responding was the fir...

No you didn't. That is the first time you have proposed that as an answer to my question, or that you have even mentioned the word 'ratio' in your rep...

They don't need to. Where I live gun ownership is very rare and the gun crime rate is very low - partly because we have strong gun control laws, that ...

That post doesn't answer the question, and provides no new information. I had already read the context. To what ratio were you referring with your use...

You seem to be hinting at some sort of ratio being low. What ratio do you have in mind? There is no obvious ratio that makes sense, given the above se...

That doesn't follow. Even if one were to accept that preventing the commencement of any new human lives is morally preferable because it prevents all ...

That is not a fact. You may feel that you personally are preventing some suffering by not procreating. But that doesn't do anything about all the othe...

Let's try making it a bit more intuitive. Let the set of all objects be U. We don't know what properties the predicate G has, but we know that, like a...

I think it is not possible to directly control our feelings, but is possible to control what we do, and thereby indirectly control our feelings. It is...

I like BitterCrank's hypothesis, which can be boiled down to "Because of the Romans". The Romans adored Greek culture and transmitted it to their colo...
