are small, simple and generic descriptions of how a potential solution can be found.
Small
is the number of words it takes to explain and time needed to comprehend the essence of the approach at hand.
Simple
is the language that defines an approach - it has no professional jargon and/or foreign language terms.
Generic
is the nature of an approach - it is field-independent making an approach universally applicable across disciplines that have little or nothing in common.
Though I do not possess a rigorous mathematical proof, I think that a
solution to any problem, if it exists, is representable as a collection or a
chain of basic approaches carefully strung together in a particular order -
taking one's clothes off first and then stepping into a shower is quite
different from stepping into a shower first and then taking one's clothes off.
Find here a sampling of basic approaches that I was able to identify and set in a concrete problem-solution context.
