ruler - the underlying geometry |
| When one circle
rolls on the outside of another circle the curve described by
one given point |
| on the edge of the
outer circle is called an epicycloid. Of interest to tai chi
ruler students is |
| the size of the
inner circle you make as you roll the outer circle (the end of
the ruler). |
| If the end piece
of the tai chi ruler is 2 inches in diameter and you are rolling
the ruler around |
| a smallish six
inch circle the relevant epicycloid looks like the picture
