I contend that impulsively triggered star formation is at least as important as spontaneous quasistatic star formation regulated by ambipolar diffusion, and probably more so. To support this contention, I describe and discuss SPH simulations of (i) star formation triggered by colliding clouds and expanding nebulae (HII regions, stellar-wind bubbles, and supernova remnants); (ii) violent interactions between protostellar discs and the resulting genesis of binary systems and low-mass companions; and (iii) protostellar collapse induced by a sudden increase in external pressure.
