Unfortunately, due to a tragic turn of events, the visiting researcher I was supposed to collaborate with won't be turning up here after all. His father in law has been diagnosed with a terminal illness, so obviously he's not in any mood for work. I hope he hears good news in the near term at least, the long term prognosis isn't at all good.
In the meantime, that means that London socializing will probably begin in August, instead of July. I'm still cranking away at the research work.
