Toshikazu Kawasaki (川崎敏和, Kawasaki Toshikazu, born November 26, 1955 in Kurume, Fukuoka) is a Japanese paperfolder and origami theorist who is known for his geometrically innovative models. He is particularly famous for his series of fourfold symmetry "roses", all based on a twisting maneuver that allows the petals to seem to curl out ...
Satoshi Kamiya – one of the youngest geniuses of the origami field (born 1981) [2] Kunihiko Kasahara – devised a standardized method for creating many modular polyhedra; Toshikazu Kawasaki – Japanese mathematician famous for his Iso-area folding theory and his many geometric folds, including Kawasaki's "Rose"
The Yoshizawa–Randlett system is a diagramming system used to describe the folds of origami models. Many origami books begin with a description of basic origami techniques which are used to construct the models. There are also a number of standard bases which are commonly used as a first step in construction.
Kawasaki's theorem or Kawasaki–Justin theorem is a theorem in the mathematics of paper folding that describes the crease patterns with a single vertex that may be folded to form a flat figure. It states that the pattern is flat-foldable if and only if alternatingly adding and subtracting the angles of consecutive folds around the vertex gives ...
Geometric Origami is a book on the mathematics of paper folding, focusing on the ability to simulate and extend classical straightedge and compass constructions using origami. It was written by Austrian mathematician Robert Geretschläger [ de ] and published by Arbelos Publishing (Shipley, UK) in 2008.
A fold F 1 (s) perpendicular to m 1 through its midpoint will place p 1 on the line at location d 1. Similarly, a fold F 2 (s) perpendicular to m 2 through its midpoint will place p 1 on the line at location d 2. The application of Axiom 2 easily accomplishes this. The parametric equations of the folds are thus:
World Origami Days [17]: a 2-1/2 week celebration of the international community of origami World Origami Days is held each year from October 24–November 11, with the goal of making origami as visible as possible by teaching a class, folding on the bus, giving origami to friends, exhibiting your models, etc. October 24 is the birthday of ...
