  The field of attosecond physics has seen an almost explosive growth since the
early 2000's and represents by now an increasing fraction of contributions to
the bi-annual series of International Conferences of Photonic, Electronic, and
Atomic Collisions (ICPEAC). The latter is anything but a coincidence as many of
the underlying concepts of electronic and photonic dynamics are closely
intertwined with atomic-scale collision processes. We illustrate this fruitful
connection and its implications with the help of a few prototypical examples of
current topical interest.
