Rod Quivering in an Earthquake---I

are N measurements of the length of a
rod.
- Owing to a Gaussian earthquake (or a Gaussian i.e., normal
drunkenness) occurring during measurement, the

about the true value:

up) who

true length and standard deviation 
.
- We may write down the (relative) probability of each measurement
