There are many corollaries to the uncertainty principle. Another is that 
it is impossible to measure a system without disturbing it.  Many 
examples. You place a voltmeter across a circuit, it draws some current, 
which changes the voltage. You want to know the temperature in a closed 
space, you open the door to measure it and the temperature changes. Or 
the presence of the thermometer changes the thermal mass slightly. And 
so on.
