title: From bacteriophage lambda to nonlinear dynamics.
abstract: Thirty years ago, Waclaw and myself were working on the same organism and had the same type of interest. Since that happy time, our trajectories have diverged so much that I am afraid any paper I might offer for his jubilee would seem completely strange and irrelevant to him and as well to his colleagues. For this reason, I decided rather to offer Waclaw, as a modest present, a product of my recent work which I consider, perhaps presumptuously, as an 'oeuvre d'art' (of course, this qualification is not supposed to apply to this paper as a whole, just to the figure). Please note above the expressions 'divergent trajectories' and 'strange'; we will meet them again below in a different context.
