NONLINEAR DYNAMICS AND COMPLEX KINETICS Oscillations and other periodic rhythms are common phenomena in physics and biology. Certain oscillations govern everyone??s life, such as day/night rhythm and heart beat. For a long time, chemists believed that their field of research was excluded from this pulsating universe. Today, however, we know that many reactions are more than simple one-way streets. Chemical systems can show oscillatory, quasiperiodic, or even chaotic behavior. More surprisingly, a large number of aqueous reaction media can form pr opagating waves which share intriguing features with propagating waves in neuronal or cardiac tissue. Thin layers of these reaction solutions generate macroscopic patterns such as rotating spiral waves (see the figure) that sometimes can be seen with the naked eye. The list of systems in which these rotating spirals have been observed is long and ranges from catalytic surfaces to heart muscles and brain tissue. Our group is studying these fascinating wave patterns in two different experimental systems. The first one is classical Belousov-Zhaboti
