    Where is the edge of the universe

    An edge would make no sense at all. This suggest that our usual notion of space and time makes no sense, which of course it doesn't, since it gives rise to the question you've asked.

    Classical Music and math?

    There's lots of examples - Stockhausen, Boulez, Bach, Stravinsky et al. Then there's 'ten green bottles, hanging...' It's a natural thing really. Music is all numbers. We might say that Debussy was using maths by dividing the octave into six tones. Boulez is one of the most interesting I'd...

    Looking for other proof of expanding universe.

    Yes, this is why I brought it up here.

    Looking for other proof of expanding universe.

    Not according to the glossy TV documentary I watched a couple of weeks ago. They reported well-observed and significant effects and discussed them with the researchers. All quite excited about it. I don't think I dreamt it but you never know.

    Looking for other proof of expanding universe.

    I heard recently that different frequencies of radiation have been measured to travel at different speeds on their way through space to us. Is it possible that this bias in the arrival time of different frequencies could affect our measurement of distances to objects?

    Effort to get us all on the same page (balloon analogy)

    Re: Effort to get us all on the same page (balloon analogy anyone?) No it's okay. I'm happy with my way of thinking about it. I'd say that the topography of the universe is unrepresentable as a visual model, and so within quite wide limits it would be a matter of personal preference how we do...

    Effort to get us all on the same page (balloon analogy)

    Re: Effort to get us all on the same page (balloon analogy anyone?) I have no ability to understand a sphere with nothing off the surface. I'd rather have Plotinus's hypersphere. This is more or less a balloon analogy, with the spacetime universe on the surface as usual, but it has a centre and...

    Philosophy forum closing

    Shame. Perhaps it could reopen when you find a philosophical moderator or two. I have to agree though that the forum was awful as a free-for-all.

    Is there a problem in assuming the universe has a boundary?

    Then you have to sit in a room and and speculate on the meaning of what the telescope has revealed. I really cannot get this idea that thinking is useless compared with experiment. I'm afraid I can't remember the discussion. I could not comment much on it anyway. I just took his proposal to...

    How would one choose between Solipsism and Realism/materialism?

    Hmm. I can't agree with much that's been said here. Solipsism has been opposed to realism, but this is not a true contradictory pair by Aristotle's rules and so there can be a third answer. Metaphysics is full of these unintentional category-errors, and they cause all the problems. I would say...

    Is there a problem in assuming the universe has a boundary?

    Would there not have to be a difference of definition between 'the whole universe' and 'all that came out of the Big Bang' in order to make sense of the latter? Here's my problem with this. Some physicists seem to have concluded that spatial extension is some sort of illusion. One calls it a...

    Is there a problem in assuming the universe has a boundary?

    Okay. But I'm assuming it wouldn't be observable for reasons already given.

    Is there a problem in assuming the universe has a boundary?

    Would I be right in thinking that a boundary to the universe is an absolute, and that physics does not deal with absolutes.

    Where to start on the path of enlightenment?(and other help)

    I sympathise. If we had to make do with only what we are taught in schools these days life wouldn't be worth living. I had to spend half my time de-programming my kids when they were younger. I expect I detest our education system more than you. I'm in the UK so it may not apply in your...

    Near Death Experience: theoretical implications contingent upon validity of claim?

    Re: Near Death Experience: theoretical implications contingent upon validity of claim I didn't mean to start a row, Ryan, and sorry if I made one likely. I just felt that Evo's approach was infused with temperament and preconception, while Nesp's was scientific, impartial and not carefully...

    Do abstract things and spiritual things exist in addition to physical things?

    The answer mat be in the question. A 'thing' must (seem to) exist, at least as a thought, to be a thing. But this is not to say that there is not an unmanifest phenomenon that cannot properly be called a 'thing'. Indeed, such a phenomenon is very useful in ontology, as Kant an Hegel show.

    Near Death Experience: theoretical implications contingent upon validity of claim?

    Re: Near Death Experience: theoretical implications contingent upon validity of claim I'm sorry mate, but from your exchange with Nesp I'd say your understanding is not great. Or not as great as his anyway.

    Irrational Numbers

    H - Many thanks for a really helpful post! Maybe what I'm exploring is to do with the boundary between mathematical formalism and realism. I'm now a little more clear about one or two things and I'll shut up about this now. Btw - re the primes - I'll stop bothering you about this also. I've...

    Irrational Numbers

    Hurkyl? Anybody? I'm getting a little bit paranoid at the lack of response. Was that not an appropriate question here? I suppose it's not exactly a mathematical question. Or is it? It wasn't a trap anyway. I was trying to understand how mathematicians see these issues, exactly where they feel...

    Irrational Numbers

    Thanks. (I was careful to add 'in the everyday sense' when I used these words.) That's how I imagine points are usually defined, as the end point of a never ending process. I assume that they simply have to be defined in this sort of way. It's the issues this raises that interest me. Very...

    Irrational Numbers

    Hurkyl - I think I can accept what you say (and I do) without it altering my general point, which comes exactly from trying to understand what parts of the object really do correspond to the math and what parts are simply errors of approximation. For most objects there may be no problem being...

    Oh yes. I see. Thanks. In that case it's a good point. But I wouldn't agree.

    Irrational Numbers

    Differently to what? Damn silly question is the answer most people would give.

    Irrational Numbers

    Yes. Is it not a surreal fantasy about infinitely thin knives that produces a useable definition for infinitely 'thin' numbers? Whether such numbers exist (or whether numbers can be coherently defined in this way), I was suggesting, can be determined from examining the definition. I suppose...

    Irrational Numbers

    For me the question is not whether these numbers exist but what they actually are. Whether they exist would seem to depend on how we define them.

    Is it possible to simplify the RH problem?

    Okay CRG, I've decided to book some tuition in order to get to grips with the issues and will stop bothering you. I need to take a few steps back before trying to go forward again. Many thanks for your patience. Much appreciated. Regards Pete

    Is it possible to simplify the RH problem?

    Thanks - even if it's all hieroglyphics to me. I realise it's a struggle to talk about this with a mathematical duffer. I was wondering whether proving the zeros behave in a certain way is equivalent to proving that the relevant inputs have certain properties. But even if this question is...

    Is it possible to simplify the RH problem?

    Yes. Simplifying problems is a hobby. It works for the TPC, Russell's paradox and many other problems, (and it kept my business alive through many a crisis). I was wondering if it would work for RH. Seems highly unlikely at this point. CRG - For you the point about inputs and outputs may not...
