Impressions from Henry Tye’s talk July 2, 2007

Posted by dorigo in humor, language, news, personal, physics, science.

I hereby admit my inability to report on the talk given by Henry Tye this afternoon at PASCOS, “Brane Inflation: an Update“, for obvious ignorance of the matter discussed therein.  I can only offer three passages that for some reason stuck in my mind, while I was trying to grasp the overall picture (my brane brain tends to find the humorous side of things when everything else fails):

“…We may have a brane, or maybe we don’t“.

A brane can go down the throat, slower and slower, but it still gets relativistic“.

some can be excited, and some can be so excited that they have cosmic string size“.

I expect the hope is that the branes excited to cosmic scales would radiate gravitational waves in some LIGO-friendly manner, à la Davis and Kibble (2005)?

LOL! My, your brain wanders a bit during talks …. please keep reporting, even if you don’t feel like telling us anything about the physics content.

Dear Blake,

I did take notes of a talk given previously by Jim Hough. In fact, I think I will post about it later. In it he explained the discovery reach of Ligo, Virgo, and the other ground-based GW experiments. However, he never mentioned excited branes if I recall correctly, but much more mundane happenings such as black hole meetings or pulsar dances.
Tye did try to construct his talk around a scenario that according to him gave “a richness of observational features”. I think I was wearing the wrong pair of glasses, though.

Kea, I am reading the sentences back and can’t help laughing again. I must be sick, indeed. I will try to give more meaningful reports tomorrow, when talks are at a level I should be able to grasp.
