The condensed matter community has witnessed a major breakthrough in the spring of 2018.

Experimental observation of strongly correlated electron phases, including superconductivity, in a system consisting of two graphene sheets placed on top of each other at a precisely tuned value of the twist angle, will almost certainly have ramifications shaping the field in years to come.

This colloquium will describe the experimental findings and try to place them in the context of known phenomena in graphene.

It will also describe some of the theoretical ideas which have been formulated since the discovery.
