I was at a meeting today with lots of other people, and a few minutes towards the end was devoted to celebrating 50 years of this and that, with pictures.
One of the pictures showed some students using optical stuff in the physics sort of way.
I was a few rows behind a row of physicists, and in unison, they said, fairly loudly, "hey, we still use that same equipment."
And everybody laughed through the room. It's probably true, too.
It can't have been planned, can it? I mean, I didn't know they were going to show 50 year old pictures. I think it's just that the physics folks were all thinking the same thing and just said it aloud.
