I did this talk — basically interesting developments in gravity & related subjects — for the third time at Philcon this last Saturday. The talk was scheduled for 1pm, so I spent a few hours in the morning refreshing it.
The big news was that the OPERA project had done a second version of the experiment that saw superluminal neutrinos, dealing with some of the objections (objectinos?) to their first results. They sacrificed quantity of neutrinos to quality: going from 16,000 to 20, but getting much tighter time resolution. This made the New York Times Saturday morning, so I clipped the headline for use in a slide. Good stuff, but of course everyone wants to see Fermilab & others reproduce the experimental results.
However the combination of refreshing the talk, roadwork on Interstate 76, & a parade or some such on the Benjamin Franklin Parkway meant I got in with no time to check the AV setup before the talk. While the impromptu AV crew wrastled the difficulties into submission (thanks Margaret Trebling, Jay Wile, Ron Bushyager, & Ferne Welch!) I invited the audience to “open the theater of your mind” & painted word pictures thereon till the AV was working. Didn’t take the crew long: we hadn’t even gotten past the Black Death slide before we had light! Actually I think the difficulties may have helped the talk go over; shared troubles create bonding between speaker & audience. Lots of good questions; SRO crowd.
Had a lot of fun on the six panels I was on; will post on them over the next few days.
