I think Tai Chi and Aikido have an apeal to new agers because there is a mystical element within them. That's to say that there appears to be a power at work that's beyond the exertion of normal human strength.
"Appears" being the working term.
I'm intrigued by this, too, but I explain that there is at least a solid working theory of physics behind every technique. Tenkan exploits the power of centrifugal force, for instance.
Ack! What "centrifugal force" is that?
Besides, even if there were a centrifugal force (which there's not), I don't think that's the idea behind tenkan; tenkan still uses the opponent's force.
