Discussion Overview

The discussion revolves around the nature and significance of axioms in mathematics, particularly focusing on which axioms are considered most important or widely used. Participants explore various mathematical systems and their axioms, as well as the implications of these axioms in different contexts.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant reflects on taking axioms for granted and questions which axioms are the most important, referencing a Wikipedia list of axioms.
  • Another participant humorously suggests that axioms may not be that important.
  • A participant emphasizes that the importance of axioms is subjective and varies by mathematical system, noting that all axioms within a specific system are equally important from a logical perspective.
  • Euclidean plane geometry axioms are mentioned as an interesting system to explore.
  • One participant humorously states they are using ZF set theory along with the assumption of odd perfect numbers to conclude that dragons exist.
  • A constructivist approach is suggested as a way to demonstrate the existence of a dragon, implying that a tangible example would be necessary.
  • There is a discussion about the distinction between operations (like addition and multiplication) and axioms, with a participant arguing that operations follow logically from axioms describing number ordering.
  • Another participant reiterates the need for a suitable definition of a dragon in the context of the previous claim.
  • A follow-up question is raised about the necessity of a specific definition for a dragon, suggesting that any definition might suffice.

Areas of Agreement / Disagreement

Participants express differing views on the importance and nature of axioms, with no consensus reached on which axioms are most significant or how they should be defined in relation to operations.

Contextual Notes

The discussion highlights the subjective nature of defining importance in axioms and the potential for varying interpretations based on different mathematical systems. There are unresolved questions regarding the definitions and implications of axioms versus operations.

Another thread got me thinking...

Everyday I take axioms for granted, eg. muliplication, addition, ordering of reals.

From the pure point of view, what axioms are the most important (most used) ones?

Wikipedia has a list: http://en.wikipedia.org/wiki/List_of_axioms

However, I'd like to know the purists opinions :smile:

They're not that important, then?

:biggrin:
 
You will have to tell us what you consider to be "important".
Mathematics involves an enormous number of "systems" each of which has its own axioms. Within a specific system, from a logical viewpoint, all axioms are equally "important".

The wikipedia list you cite is essentially a list of axioms for set theory.
 
A neat system of axioms to explore are the Euclidean plane geometry axioms.
 
I'm using ZF + "odd perfect numbers exist" and trying to conclude that dragons exist.
 
It think a constructivist approach would be best for that- exhibit a dragon!

Seems to me that multiplication and addition are operations not axioms. Once you stated an axiom describing the ordering of numbers, operations like addition and multiplication would follow logically and would not require additional axioms. No?

well, you just need to adopt a suitable definition for a dragon!

Why? I'd think any old definition would do.
