Ok...I'm new to these forums and am just beginning to understand quantum physics, so please be kind. I've been reading those Brian Greene books and I have a question that I don't think he addressed.
If I understand correctly, some believe that IF we could measure the position, velocity and direction of all particles we could then predict with absolute certainty where they will be at any time in the future or would have been at any time in the past. Heisenberg says we can't do this, not even for one single particle because the more accurate our measurement of the location of a particle becomes, the less accurate our measurement of its speed and direction becomes. So far I get it.
But let's assume we could get both the postion and velocity and direction of all the particles in a system (say...me and a cup of coffee with cream). We make our calculations and predict that in 10 minutes the system will look like X. During those 10 minutes I stick my finger in the system and stir it around.
My question is this...Will knowing the exact position and velocity and direction of all the particles that make up ME somehow predict that I am going to stir the coffee? Do I have any freewill? Or is my every move somehow predictable based the current state of my matter?
Thanks,
LoonBoon
