Huzita-Justin Axioms
At the First International Meeting of Origami Science and Technology , Humiaki Huzita and Benedetto Scimemi presented a series of papers, in one of which they identified six distinctly different ways one could create a single crease by aligning one or more combinations of points and lines (i.e., existing creases) on a sheet of paper. Those six operations became known as the Huzita axioms . The Huzita axioms provided the first formal description of what types of geometric constructions were possible with origami: in a nutshell, quite a lot was possible! The six Huzita axioms. The six axioms are shown to the right. It has been shown that using the six Huzita axioms, it is possible to:
Uses: The Monkey's Fist ( ABOK # 2200 - 3, p 354) is used both as a decorative knot and to weight the end of a heaving line (see caution below). Tying it: The Monkey's Fist is usually tied around separated fingers. For the demonstration, a U-shaped piece of metal strip was used instead and three turns of rope were used in each direction. After each set of complete turns, change direction by passing the end through the middle. For each direction count carefully: it is very easy to miscount and have more strands on one side than the other.
