I've just finished reading Einstein's Biography by Walter Isaacson. There is a pasage that got me thinking about the way Einstein observed the universe and his distaste for quantum mechanics. Einstein is famous for declaring that God dose not play dice, basically what he was saying is that, even though we perhaps do not fully understand what is happening there is a strict set of rules governing reality. From what i understand, quantum mechanics states that one cannot predict to an absoulte certainty what and where something(such as a particle) will happen next, it can only predict the possibilities of what or where something will happen next, in other words as one observes in greater detail the postion of a particle one loses the detail of its vector and vice-versa. I think thats right..anyway... I was sitting outside late one night after it had rained and drops of water were on occasion dropping off the roof, now of course one could not predict exacly when and where they would drop off but it made me think that there was some rule determining when and where it would, the water would build up until it hit breaking point and was too heavy too support its own weight and fall to the ground under graivty. To me that looks like a definite line upon when reached a significant event would happen. In other words there was no chance involved just a series of events that led upto the final action (the raindrop hitting the ground). of course there are many factors involved and the calculations to acheive a accurate prediction would be extremly and perhaps impossible at out level of understanding but what i think im trying to say is that to me there seems like a strict causality in our universe even if perhaps we still dont full understand it. What do you think?
