A meditation on the not-quite cyclic nature of time, and how both the linear and circular models of time may be correct simultaneously. Soundtrack: “Clocks” by Coldplay and “Time after Time” by Cyndi Lauper

The possibility of time travel is actually still an open question. There is nothing in Einstein’s theory of Relativity that prevents it from happening, although the conditions that would be required to allow it to happen seem pretty insurmountable. (For example, you would need a rotating universe, or a nearby cosmic string, or some exotic material that exerts anti-gravity which could keep a wormhole conduit stable and open, none of which are within the technological abilities of humanity at this time.) Still, I am hopeful.

Before work today, one of my chief residents was on one of the alternative music stations in town, which was bizarre and very cool. She won an hour to guest DJ and she broadcast her own playlist.
