One recurrent question which showed up during the discussions of the meeting is whether the generalisation and universality of the physicists approach are relevant for biology. The debate over this problem is certainly not over, but, according to their comments after the workshop, both communities have slightly changed their point of view. Clearly the physicists have taken a better measure of the diversity in biology and they will try to introduce a part of it in their models. Deciding how specific a model should be to be relevant is another story! Although biologists are certainly not ready to accept the extreme reductionism of many physical approaches, they have been in contact with the concepts of nonlinear science which have no counterpart in the world of linear excitations, and will perhaps integrate new ideas in their analysis.
