First let me define my use of the word paradox, in this thread. A paradox is a self-contradictory statement, or one that cannot be true, but also cannot be false. Alright, now, some have said that Quantum Mechanics meets this criteria, because it states that something can be both alive and dead at the same time. If this is what it said, then I would agree that it was paradoxical, because "dead" is the opposite of "alive" and so you cannot be both. However, it is my current opinion that that is not what QM implies. I have read that Schrodinger's (sp?) Cat is not alive or dead, it is 1/2 of each. It is in a half-way state, until an observation is made, and then it becomes one or the other. Is my understanding of "Schrodinger's Cat" correct. If not, is Quantum Mechanics paradoxical?
