Learning mathematics from a physicist is hazardous.
Learning computer science from a physicist is hazardous too.
Numbers in a computer are different from experimental measurements.


nevertheless, I like this article.  It says, among other things,

	The technique of propagating the uncertainty from step to step 
throughout the calculation is a very bad technique. It might sometimes 
work for super-simple ?textbook? problems but it is unlikely to work for 
real-world problems.
