In a study published in Nature Nanotechnology, researchers from Cornell University and the University of Jyväskylä, working with funding from the Academy of Finland, show that
by applying an
appropriate external force, a circular graphene membrane can be «played» like a drumset.
Harold and Stephen, I can't find a reply symbol next to your posts of this morning, so I'll answer here: Harold, you are right in this regard, we have not identified a central «conductor»; although, as you have seen in my posted speculations, entrainment
by an
external forcing with a similar rhythm and
appropriate coupling strength with a component or components of the climate network may be able to nudge the intrinsic oscillatory nature of the climate system.
