Nose Figure-Eight Lissajous Slip
Sit cross-legged and slowly draw a vertical figure-eight in the air with the nose, using neck and upper spine. Detect the instant the ratio slips: when the nose stops drawing a clean eight and begins drawing an oval, a tilted line, or a knotted loop.
Full Lesson Notes
Complete Practice
Sit cross-legged and slowly draw a vertical figure-eight in the air with the nose, using neck and upper spine. Stay small; stay slow. Detect the instant the ratio slips: when the nose stops drawing a clean eight and begins drawing an oval, a tilted line, or a knotted loop. The slip is data about which of the two oscillations is faltering, and which cervical segment carries the wobble. Challenge: Drawing a clean 1:2 with a freshly-attended neck is hard; the experiment may stay in always-oval territory and the slip event never materializes.
