Top Structure
[edit source]Suggestion for Top-level structure:
Basis: Proof
Supplying Mathematics
- I Understanding Maths (Meta Maths)
- Questioning Job (Axioms)
- Questioning Scientific Program (Sentence)
- Questioning World (Theory)
- Questioning Universe (Formal System)
- Questioning Maths?
- II Doing Maths ( Processor .... 'Homo Mathematicus' .... Scientific Community )
- Sign Processing / QA
- Clarity (Who can understand it)
- Scientific Community (Altruism)
- 'Homo Scientificus'-based Model (Interaction amongst them)
- Multi Community Model (Maths + others)
Applying Mathematics
- III Understanding Application (Application to the real world (and beyond ?))
- What is the real world like?
- What Theory to choose on the Maths side?
- How to apply the Theory chosen?
- How 'good' can this approach be ( compared to others )
- IV Doing Application ( The Process )
- Elements
- Players ( Processor ... 'Homo Mathematicus'... Opportunist )
- Interactions ( stand alone ... virtual ... restricted )
- Areas ( Science, Engineering, ... )
- Models
- Stand alone Models
- Virtual (unrestricted) Communities
- Restricted Communities
- Restrictions in the real World
- Models of Communities
- Elements

On Structuring
[edit source]Questions:
- How to write it down?
- What formal concepts of Proof do exist?
- How can I be sure that my Proof is correct?
- Efficiency: how can I check it practically
- Effectiveness: what can i be sure of/ how sure can I be - at all?
- There are several ways to proof it - which one is the best?
- Two Proofs are said to be equal iff ... (theoretical & practical answer)
- How can I structure my Proof? (Lemmata, Corollaries & co.)
- Are there Proof-Quality-Metrics?
The 'bright' blackbox view: Mathematician also 'generates' understanding during his work.
Questions:
- Is the Proof my only result? What to do with the understanding of the Theory I have developed during my work? How can I transfer this?
- Why should I transfer it? Is this still science?
- What to transfer?
- For whom to transfer?
- How to transfer?
- Does this have an effect on the above questions?
- Shell I seperate e.g. the question for the best way to prove sth from the transfer questions?
- Does understanding help me with assuring the correctness?
- Is there a notion of a formal/understandable Proof? (In practice it is, but is this just laziness or better than pure formal approaches?)
Enhanced input view: Mathematician uses already existing work as input.
Questions:
- What existing Theorems may I use?
- The proved ones, but who decides this?
- Have I to check all their proofs myself?
- If not, who can I rely on - the scientific 'community'?
- The proved ones, but who decides this?
Introducing Definitions (belongs to bright blackbox view?)
Questions:
- What Definitions to introduce?
- What is a Definition?
- How is it defined?
- How can I write Definitions down easily?
- What is it good for?
- For formality?
- For understanding?
- How to decide on 'define or not define'?
- What to define always?
- What to define never?
- Are there good/bad examples?
- What is a Definition?
More Questions:
- What are the properties of the Theory? (sound, complete, ...) e.g. can I find a Proof at all?
- Is the underlying Logic (concept of Proof) the right one?
...
Questions concerning the scientific program:
- What Theorems to approach? (esp. does it make sense to prove this Theorem at all?)
- What is the role of this Theory amongst all other Theories?
