I can never keep Schrodinger's cat and the Heisenberg Uncertainty Principle straight. They both seem to state that by measuring or observing something, we change it. Stick a thermometer in a glass of watter, the thermometer will affect the temeratrure of the water so you will never truly know what the temerature of the water was befor you measured it. It's late and all this thinking is making my brain hurt. I'm going to bed so I can getup early tomorrow, put on funny clothes and do some 18th century shopping.
