Yesterday evening I chanced to attend, invited by a friend, the opening of the 2013-2014 academic year of the university of Venice "Ca' Foscari", which was held at the Malibran theater. It was the first time I attended one such event, since technically (and practically) I am not an academic, but a researcher at the INFN, the Italian National Institute of Nuclear Physics. I do occasionally teach university courses (I just took a break from doing so after 5 years of teaching a course of subnuclear physics for 5th year undergraduates); but I do that for the university of Padova, not Venice - my office is at the department of physics of the university of Padova. Besides, Venice does not have a course of laurea in Physics.

The recent movie "Gravity", featuring the two hollywood stars George Clooney and Sandra Bullock, is a very interesting experiment in film-making.

I can hardly recall other movies with just two characters, so this must clearly be a rare occurrence and one which shows that the movie treads in largely unexplored territory. Can people be entertained by one-man shows ? Well, yes, if the story is an extraordinary one. Tom Hanks does excellently in "Cast Away", for instance. "Gravity" is similar in the use of the loneliness of the protagonist and the large odds against her survival. But it is more radical in the total absence of other human figures, except Clooney of course.
