That is bogus beyond belief. The
Heisenberg Uncertainty Priciple mainly invoved predicting the position
of an electron around an atomic nucleus. Even a single photon of
light (the mechanism of "observing" / measuring the electron's
position) would radically offset the electron, so you'd never know
where it was at before the "measuring" photon hit it.
If the Measurement / Measured relationship
is on the scale of Photon / Electron, then there's reason to be concerned.
However, realistically, the amount of heat extracted from a person's
body to expand the mercury in a thermometer to measure that person's temperature
introduces no error in the measured temperature.
Unless your database monitoring tool
is more like a sledgehammer than a stethoscope, you're OK.
Of course, that's IMHO.

Subject
Heisenberg and measurement intrusion....
I'm on an Oracle performance project and a project
participant made a
statement regarding measurement intrusion.
Is the statement below accurate?
"So the Heisenberg uncertainty principle mandates we run without monitoring
as a baseline."
I responded with a wikipedia link which I'll send later, but I'd like to
get
opinions first. :)
