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. 73, Jim K9YC ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
