If something exists, it can be explained by physics. And sure, I do not need to understand how an internal combustion engine works in order to own a car, but the engineering degree sure makes driving the car a more controlled and enjoyable experience, makes fixing or modifying the car MUCH MUCH easier, and makes educating someone else on how to operate, repair, maintain and customize their car much easier.
Complex neuromuscular physiology is basic physics, from the ion pumps that transmit nerve impulses to the force vectors inherent in a muscle contracting in order to move a bone or two. This IP stuff is SCREAMING for an ambitious bioengineering grad student at a liberal and well funded college, or a couple NSF grants. Hmmmmmm. IP or sustainable energy engineering? Hmmmmm.
I doubt anyone would consent to performing their stuff stuck full of EMG leads. Suckers hurt.....
Well, of course any kind of movement, or even non-movement, can be broken down into pure physics, just as all life processes can be parsed out to the molecular (and atomic) level. My point is that such knowledge is close to (if not entirely) useless to the actual process of learning and doing, and is just so much more clutter that obstructs the path.
What possible good is discussing the minutiae of physics in movement, when it won't do an iota of good in teaching you how to actually fire your mind and move your body properly? General concepts and principles, such as tangent points, arches, spirals, and maintenance of spherical forces are useful, but only in the context of the actions we are training within our bodies. Without an experiential understanding of what is being done with the human mind, frame and tissues to create, manipulate and manage forces/energy within the body, people are left with only conjecture of the role of theoretical physics in the process.
This is one area where Western thought remains its own worst obstacle to learning "new" concepts. At some point, we need to silence the chatter in the brain and learn to feel and do first, then
discuss. So, once again... go out and train with reputable IP/IS people. It will open up a huge door to fruitful discussions.
