Abstract: The axion arises in the course of an elegant solution of the strong CP problem.
Moreover, it is a very good candidate for dark matter. I summary the physics
case for the axion, emphasizing recent developments in axionic physics.
To complement the colloquium we will have another edition of our “Theory meets Experiment” series in the afternoon (14.00, H331) on “Detecting Axions"
