The closest that anyone I have seen come to this type of Western theory of action is Adele Westbrook and her husband, may he rest in peace, Oscar Ratti. Oscar Ratti's illustration work is particularly valuable in this regard. He had a keen sense of dynamics and a gift for representation in simplified schematic form. His images, if not their attempt at overall sytemization are a serious start. They basically interpreted the traditional mode into non-jargon English. They did not critically examine the nature of the system itself or really even attempt to describe a theory of action in physical or mechanical terms. Of course, no one else really has either.
While I appreciate their effort and realize their work had the best intentions, it's my opinion that "The Dynamic Sphere" has done more to obfuscate the real core of aikido than just about any other published work. They simply were not in a position (in terms of their own understanding or training) to offer THE book on the nature of Aikido. I'm sure others will disagree with me greatly (although I would be surprised if Dan, Rob or Mike do).
