Very nice! One minor glitch -- your second article ("How Precise is my Measurement?") says "a famous mathematical theorem (Ref 5) relates that the mean value of an arbitrary signal is usually Gaussian." Well, there are only 4 References in your list, and I'm not sure if any point the reader to the Central Limit Theorem (which says that for any distribution, the distribution of the mean of a series of measurements tends towards a Normal Distribution).
I look forward to reading more Blog posts ...
