Probability rate of calculation

  • #1

Main Question or Discussion Point

Hi all
I'm sure this has been asked before and I'm hoping someone be kind enough to direct me to the answer. Which is probably 'you're question is nuts' :)
Particles interact with each other and this affects the probability of where they are? Right so far I hope. This probability has to be calculated somehow (by the particle)? What is the speed of the calculation? Infinite?
Thank you

If you simulate a physical system with a computer, it takes some non-zero time to calculate the dynamics. Sometimes it's possible to do the computation in ##\textit{polynomial time}##, meaning that the time requirement grows no faster than some power of the number of particles in the system. Sometimes the time requirement grows exponentially.

Nature itself does not need time to "calculate" what to do, at least there is no evidence that it would.
