Oxford-Beer-Cambridge

So it is summer and time for my annual visit to the UK. I usually spend two weeks in DAMTP, Cambridge, visiting Anne Davis. This year I also included another short visit for Stephen Hawkings' 75th birthday in Cambridge too. On the way I went to Beer (East Devon) and Oxford where my sister and mother in law reside. As usual it's busy as we try to cram as much physics as possible in two weeks. This time it was all about the two body problem in General Relativity and beyond, the quantum Hall effect and tensor modes from multigravity theories with the CMB in mind. Not everything is shipshape yet and some work needs to be done before publication but at least we have laid the foundations for busy weeks in the autumn. I was also the organiser of a special session in the biannual meeting of the French physical society in Orsay about dark energy and modified gravity. This was the day after coming back from Stephen Hawking's do and apparently, so people say, the four speakers (Pierre Astier, David Langlois, Patrick Valageas and Guillaume Pignol) managed to combine their presentations nicely to present results from cosmological observations to laboratory experiments via beyond Hornedeski theories... Now Dover-Calais on the ferry and after a few days at home in Etrechy, some well deserved repose down south.
