They soon see another wooden model. It has two toy cars, one moving up and down an incline and the other up and down a helical ramp winding inside a cylinder.

Each step he takes creates a musical tone. A melody emerges as he continues down. Ichiro and Jai follow but they are curious to see what will happen if Ichiro goes ahead and Jai follows a few steps behind. They ask Yasu if they can do this and he consents. As they traipse down, a blending of tones is heard. The musical stairs are two stories high and actually bring them to the basement of the building. At the base of the stairs are two posters, one about the staircase, another on music and mathematics.

It’s a curved road,” Ichiro observes. “Maybe that’s another special curve,” Jai ventures. ” One of the guides, Hiro, overhears them and tries to explain. “There are some conditions that must be met so that the square wheel can move smoothly over a curved road. The length of a side of the wheel must be equal to the length of a segment of the curve. As the wheel moves forward, its side is always tangent to the curve. ” 36 Hiro leads them to a computer screen where they see a square moving forward along a curved road.
