2. New Scientist, June 30, 1990, p. 37.

Q12b: What are laboratory demonstrations of chaos?

A12b: Robert Shaw at UC Santa Cruz experimented with chaos in dripping taps. This is described in:

1. J. P. Crutchfield, Chaos, Scientific American 255, 6 (Dec. 1986), pp. 38-49.
2. I. Stewart, Does God Play Dice?: the Mathematics of Chaos, B. Blackwell, New York, 1989.

Two references to other laboratory demonstrations are:

1. K. Briggs, Simple Experiments in Chaotic Dynamics, American Journal of Physics 55, 12 (Dec 1987), pp. 1083-1089.
2. J. L. Snider, Simple Demonstration of Coupled Oscillations, American Journal of Physics 56, 3 (Mar 1988), p. 200.
