Yesterday I braved the inclement weather and the perils of weekend travel on Southern Trains to visit Queen Mary College, in the East End of London, for the following event:
I used to work at Queen Mary, but haven’t been back for a while. The college and environs have been smartened up quite a lot since I used to be there, as seems to be the case for the East End generally. I doubt if I could afford to live there now!
Owing to a little local difficulty which I won’t go into, I was running a bit late so I missed the morning session. I did, however, arrive in time to see my former colleague Bangalore Sathyaprakash from Cardiff talking about gravitational waves, Jim Hough from Glasgow talking about experimental gravity – including gravitational waves but also talking about the puzzling state of affairs over “Big G” – and Pedro Ferreira from Oxford whose talk on “Cosmology for the 21st Century” gave an enjoyable historical perspective on recent developments.
The talks were held in the Great Hall in the People’s Palace on Mile End Road, a large venue that was pretty full all afternoon. I’m not sure whether it was the District/Hammersmith & City Line or the Central Line (or both) that provided the atmospheric sound effects, especially when Jim Hough described the problems of dealing with seismic noise in gravitational experiments and a train rumbled underneath right on cue.
UPDATE: Thanks to Bryn’s comment (below) I looked at a map: the Central Line goes well to the North whereas the District and Hammersmith & City Line go directly under the main buildings adjacent to Mile End Road.
Anyway, the venue was even fuller for the evening session, kicked off by my former PhD supervisor, John Barrow:
This session was aimed at a more popular audience and was attended by more than a few A-level students. John’s talk was very nice, taking us through all the various cosmological models that have been developed based on Einstein’s theory of General Relativity.
Finally, topping the bill, was Sir Roger Penrose whose talk was engagingly lo-tech in terms of visual aids but aimed at quite a high level. His use of hand-drawn transparencies was very old-school, but a useful side-effect was that he conveyed very effectively how entropy always increases with time.
Penrose covered some really interesting material related to black holes and cosmology, especially to do with gravitational entropy, but my heart sank when he tried at the end to resurrect his discredited “Circles in the Sky” idea. I’m not sure how much the A-level students took from his talk, but I found it very entertaining.
The conference carries on today, but I couldn’t attend the Sunday session owing to pressure of work. Which I should be doing now!
P.S. I’ll say it before anyone else does: yes, all the speakers I heard were male, as indeed were the two I missed in the morning. I gather there was one cancellation of a female speaker (Alessandra Buonanno), for whom Sathya stood in. But still.Follow @telescoper
