On a train, you overhear a woman phoning her office. Why has she phoned?

Woman:  Jenny, hi, it’s me. I’m on the train and it’s stuck somewhere just outside the station -- signalling problems or something ...Yes, I know, sorry, but there’s nothing I can do about it. Anyway, listen, could you check my diary and see when I’m supposed to be with those marketing people ... it’s on my desk  ...... Oh, isn’t it? Oh, that’s strange. And it’s not in the drawer? I wonder ... Oh, I know, I must have left it in Jimmie’s office after yesterday’s meeting. You couldn’t get it and then ring me back, could you? Sorry to be a nuisance.

Interviewer:   It’s difficult to talk about the beauty of a sound, but our great musicians today still clearly feel that these sixteenth-century Italian violins are the best. Do you agree with them?
Scientist:  Well, if you look closely at a violin, um ... it may be a beautiful-looking instrument, but it is basically just a wooden box, whose function is to take a little energy out of the string that the musician plays and to turn it into sound that is then heard by the listener. The function of an individual violin is to provide suitable playing and sound qualities for the musician to express all of his or her emotions.
