Re: [Phys-l] FW: universal gravitation lab

[Jack Uretsky <jlu@hep.anl.gov>]

Well, that's the part of real experimental physics that the simulations 
don't catch'  Also, the leaks in the vacuum system, the burned out 
electronics, and the lab assistants whose minds are elsewhere.  Some of 
us experience these vicissitudes early on and opt to become theorists.
