Discussion Overview

The discussion revolves around a series of mathematical questions posed by a participant regarding the nature of certain mathematical constants (pi, e, i), their representation, and their implications in various branches of mathematics and philosophy. The scope includes conceptual inquiries, explorations of mathematical beauty, and the relationship between mathematics and human experience.

Discussion Character

  • Exploratory
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant questions whether pi, being infinitely long, cannot be accurately represented or known, suggesting that only approximations can be used.
  • Another participant argues that while the decimal representation of pi is infinite, it does not affect the mathematical properties of pi itself, which can be used exactly in proofs.
  • There is a discussion about whether it is impossible to accurately represent the area of a circle due to the nature of pi.
  • Some participants inquire about the connections between pi, e, i, prime numbers, and chaos theory, seeking to understand their relevance in modern mathematics.
  • Questions are raised about the criteria that make a mathematical proof "beautiful," including efficiency and the use of analogies.
  • Participants express differing views on the relationship between the lives of mathematicians and the creativity of their work, questioning whether interesting mathematics arises from interesting mathematicians.
  • There is a suggestion that some questions may be better suited for philosophical discussion rather than strictly mathematical inquiry.

Areas of Agreement / Disagreement

Participants express a range of views, with some agreeing on the nature of mathematical representation while others challenge the framing of the questions. The discussion remains unresolved, with multiple competing perspectives on the nature of mathematical constants and their implications.

Contextual Notes

Some questions raised involve assumptions about the nature of mathematical knowledge and representation, which may not be universally accepted. The discussion also touches on the philosophical implications of mathematical concepts, indicating a potential overlap between mathematics and philosophy.

Even worse, your post #1 reads like a parody of views concerning mathematics which (to judge from popular literature and newspaper stories of the time) were held by many persons at the beginning of the last century

I'd love it if you would expand on what you think those views were in the early 1900s, either in this thread or a new one. I'm curious, largely because I don't have a feel for this aspect of math history.

Chris Hillman said:
I suggest that this thread be locked, but perhaps someone will care to start a new threads on "What are the current top ten popular myths about mathematics?", "What is mathematics, that thou are beauteous?", or even "Numbers: is math propaganda in the national interest?" :wink:

I may just start that first thread.

Yes. Is that easier to understand than what I posted (n has a terminating base-b expansion iff rad(b) = rad(n))?

As I don't know what rad of a number is, it is a damn sight easier for me to understand. Though of course I should have read your post more thoroughly.

Not sure what happened to Chris Hillman's post, but would like to know what he or anyone else thinks of this...

When mathematicians describe a proof as "beautiful" they can mean one of three things:

One, because it is succinct, aerodynamic, and efficient, like a golfer’s stroke.
Two, because it links unexpected lines of thought, like a poet’s metaphor.
Three, because it somehow vanishes into infinity, like the light of the ribs of the branches of the trees of the forest of the planet of the space of the light…

Feel free to be as contemptuously dismissive as you like chaps.

The first two would be reasonable, and are almost the descriptions that occur in the book by Gowers that you initially said didn't contain any answers to your questions. I don't remember him putting in the similes. If you want to get a better understanding of mathematics/mathematicians, then I would say that a mathematician wouldn't have inserted those similes since they don't help to convey anything, and are just as open to interpretation. I can't make any sense out of the last one.

Reportedly someone died laughing while reading it :bugeye: so out of concern for public safety...

That's not funny. Try again :wink:

Do you really want an honest response?

Yes, give me an honest response. I didn't read your deleted post, just saw it quoted - see if you can find a less hilarious way of putting it perhaps?

look up the prime number theorem. it draws a connection between the natural log and the distribution of prime numbers.


also, mathetical beauty doesn't necessarily have to be succinct...at least not to me. i think a lot of beauty can come from the results, even if the process that leads to them is complicated and messy.
