If you were writing a paper for a Philosophy class I suppose that your "definitions" would be called "apriori statements".
Using your way of explaining things is analagous to one saying that a
God caused the thunder storms and eclipses. One then has to ask what is your "first cause" that produces these effects/
I really am sorry that I am not communicating well to you. I will try for the third time.
If you simply say that an effect is truley factual BECAUSE A DEFINITION
SAID IT WAS leaves something to be desired. Give your authority for that definition.
For the second time you fail to answer simple questions that a grad student
in aeronautical engineering should easily answer. Are you a Social Science Major? I have a Masters in Chemistry with a Physics Minor attached. But hey, I have known practising Electrical engineers who can't solve ordinary problems in Static Electricity.
