String topology, invented by Chas and Sullivan in their eponymous 1999 paper, can be viewed as a systematic study of the structure of spaces of free loops and strings on manifolds with emphasis on two basic operations: concatenation and splitting. I will argue that the true potential of string topology is revealed from a symplectic perspective. The menu of the evening includes string knot invariants, loop products, and fancy billiard tables.
