Interesting Mike. If that's what you must do to learn then you won't get far I'm afraid. You can use that logic for physical technical moves though.
Stealing is only copying and like all copying, it doesn't require much understanding. Good luck on your path.G.
You can copy the words of a joke, by re-telling using the same words, what happens though if you don't get the joke because the humour is too subtle or leftfield? Stealing words - easy, stealing the humour - not so.
Personally I don't think that physics is going to explain the totallity of what is happening inside the mind/body of someone doing aikido.
Sure if you get the required funding and willing scientists to wire up the willing aikidoka, you will get readings that explain the body position and condition. Where the scientists will struggle is with the measuring/quantifying what is happening in the mind of both uke and nage. How Nage uses the mind to manipulate his/her own body and how the mind is used to create the connection to uke's mind/body.
When someone can measure that, then we might be able to have a fully objective debate. Until then it's all about more of what we have at the moment, which is a bit of a messy subjective minefield.
