Memory (of facts and processes) helps in thinking things out.

But forced memory can be 'overdone' (by adding 'exact', 'holy'/'sacred', permanent,... to memory).

Recognition of 'changes'.

Understanding processes that bring about the changes.

Experimenting and measuring 'current processes' is more relevant that memory of out-of-date knowledge/facts.
