The system is fundamentally 6^N dimensional with N~10^23.
- sixdimensional 9y agoYeah, 6^N dimensions are fun! ;)
- semi-extrinsic 9y agoI suppose you meant 6*N? Which is a lot better, but still intractable. And anyway, we don't exactly resolve molecules in e.g. turbulent flow simulations, yet they still take tens, even hundreds of millions of CPU-hours.
- noobermin 9y ago6*N, yes. Pretty bad mistake there. But yes, even if you don't model every particle and restrict yourself to "parcels" of fluid like in most simulations, you still have a very difficult problem.
- igravious 9y agoOkay, this is really showing my ignorance but why 6? You start off with 4 (3 space plus one time (ignoring 11-dimensional space-time)) and add which dimensions exactly? Can the individual interactions between wave/particles be reduced to 2 dimensions? Aren't they going to interact along the whole range of forces they exert: gravitational, weak, electromagnetic, strong?
- etatoby 9y agoUnless you consider quantum effects, which are probably relevant in this situation, then it's an exponentially larger problem space.
