    For you maths-people as I'm confused.

    Does this notation mean: 0.999999... (going on infinately) ?

    Thanks for clearing that up... though I still think it's weird.

    For you maths-people as I'm confused.

    How is it possible that I can write (for example) 1/3 and be 100% accurate while I couldn't write the same number in decimals being just as accurate? It has to do with our choice of system. But what is it exactly? I don't seem to grasp it or isn't there anything to grasp?

    Have a cone and divide it into infinately small slices

    This question just popped into my mind: Is there a difference between infinitely small and zero?

    Have a cone and divide it into infinately small slices

    erm... the difference would be infinitely small? But that would still be a difference which makes it possible to glue the slices together and get the cone back again rather then a cylinder. If the difference would be zero we would get the cilinder.

    Have a cone and divide it into infinately small slices

    If I have a cone and divide it into infinately small slices. Wouldn't both sides of one slice have the same area and wouldn't the next slice (and so on) have the same area as the slice before. So wouldn't your cone actually be a cylinder? My answer is no, because the reasoning is wrong. If I...

    Is Maths an underlying principle of nature or did it originate from our brain?

    What if the french language doesn't permit talking about anything else but France?

    Is Maths an underlying principle of nature or did it originate from our brain?

    It's hard to grasp, but I would say our brain is totally-included to the underlying principle of nature. So according to me there's no such thing as a spirit besides our body. No, because I believe everything entering our brain enters the senses first. We can only think about things we have...

    Is Maths an underlying principle of nature or did it originate from our brain?

    If we now compare the television with Maths... The television works on principles of nature (physical laws). Without them we couldn't have invented the television. We regard those physical laws as discovered. With those physical laws the television isn't an so obvious object to make even...

    Is Maths an underlying principle of nature or did it originate from our brain?

    But isn't an invention like that as well? An invention is also embedded into nature. Nature gives us a potential of making certain things. When we invent the television we realized the potential of nature of producing a television. The invention of the television has always been possible...

    Is Maths an underlying principle of nature or did it originate from our brain?

    :eek: The old Greek society would turn around in their graves! It's a philosophical question, but that doesn't mean it doesn't affect Maths. I think it's quite ignorent studying Maths without questioning it's origins.

    Is Maths an underlying principle of nature or did it originate from our brain?

    I thought Mathematicians would have an opinion about this. I know the Pythagoreans had. And besides classifications only exist in the human brain. There is no exact place to put it. It's just a question of choice. I didn't post to get into an argument about where I should have put this.

    Is Maths an underlying principle of nature or did it originate from our brain?

    It wasn't meant as a question. It was meant as a think over.

    Is Maths an underlying principle of nature or did it originate from our brain?

    Is Maths an underlying principle of nature or did it originate from our brain? I think we would agree that Maths is abstract, but would it be there if we wouldn't be here? Maybe Maths is an underlying principle of nature that our brain is capable of taking notice of in an abstract way. ...
