The Science News article, Microswimmers make a splash, describes movements of living things in the microscopic world as, “… very majestic, slow and regular…” That parallels the movement one seeks to experience in Tai Chi.
Consider this quote: “Motion at low Reynolds number is very majestic, slow and regular,” the late physicist E.M. Purcell said in a famous 1976 lecture on the physics of micro-organisms “If you are at very low Reynolds number, what you are doing … is entirely determined by the forces that are exerted on you at that moment, and by nothing in the past.“
… Or future I’d add! This describes the essence of what I look for in doing Tai Chi. Picturing myself as a micro organism swimming in air can point me in the right direction. This is not far off the mark either. When I feel myself against the backdrop of eternity and the heavens above, it is easier to feel microscopic and vacant like a valley, as chapter 15 puts it.
