Re: Scientific aiki
It all depends on the individual.
In my experience as a Customer Service Engineer ( service technician ) the more an end user knows how the equipment or system works the better user they become. They can avoid common mistakes that lead to having to call for service to repair their mistakes.
A person is only able to understand up to what their education, experience and desire are.
Everybody understands differently and the more ways a teacher is able to explain a subject the more people he/she will reach.
