The adventures of Penrose, the mathematical cat

N-Y: Tetra, 1997. - 132p. Penrose, a cat with a knack for math, takes children on an adventurous tour of mathematical concepts from fractals to infinity. Penrose, a cat with a knack for math, takes children on an adventurous tour of mathematical concepts from fractals to infinity. When the fractal dragon jumps off the computer screen and threatens to grow larger than the room itself, Penrose must find out if fractal patterns can work in reverse, getting smaller instead of larger.

Penrose the cat explores and experiences a variety of mathematical concepts, including infinity, the golden rectangle, and impossible figures.
