Consider how the various explanations differ !

And ask yourself which explanations you like best and why.

Examples:
 
One difference between my explanations is that I can really produce and verify the explanation that describes a mechanism (not without the help of engineers, of course). With other explanations, checking is more complicated.

 
I like the constructed explanations best, because I can understand them most easily. However, also constructions are always only possibilities. With the construction of Heron you could open the doors, but since I did not look under the temple, I do not know what is really the case.
