 +"Can one hear the shape of a triangle?​."​
 +The problem 'Can one hear the shape of a drum?‘ was posed in a famous article by Mark Kac in 1966 and inspired a lot of research in spectral theory in the last half century. In the talk I will explain some of the main results and outline some ideas behind their proofs. I will also show how the question in the title leads to an apparently simple highschool problem about triangles, which however was solved only recently.
