### A man and his wife are dining...

A man and his wife are dining at a table in a plush restaurant, and the husband keeps staring at a drunken lady swigging her drink as she sits alone at a nearby table.
The wife asks, "Do you know her?"
"Yes," sighs the husband, "she's my ex-girlfriend. I understand she took to drinking right after we split up seven years ago, and I hear she hasn't been sober since."
"My God!" says the wife. "Who would think a person could go on celebrating that long?"

### Wallace Clement Sabine

Died 10 Jan 1919 at age 50 (born 13 Jun 1868).Wallace Clement Ware Sabine was an American physicist who founded the science of architectural acoustics. After experimenting in the Fogg lecture room at Harvard, to investigate the effect of absorption on the reverberation time, on 29 Oct 1898 he discovered the type of relation between these quantities. The duration T of the residual sound to decay below the audible intensity, starting from a 1,000,000 times higher initial intensity is given by: T = 0.161 V/A (V=room volume in m³, A=total absorption in m². The first auditorium Sabine designed applying his new insight in acoustics, was the new Boston Music Hall, formally opened on 15 Oct 1900. Now known as the Symphony Hall, and still considered one of the world's three finest concert halls.
