| Feb 4 at 6:23 | comment | added | Pertti Ruismäki | @CriglCragl Determinism is not dependent on the number of objects in the system. The idea behind classical physics is that we can treat physical systems as deterministic, even if they aren't. Classical physics of large objects is sufficiently accurate for most practical purposes. | |
| Feb 3 at 23:31 | comment | added | CriglCragl | @PerttiRuismäki: A two-body system can be considered detetministic, in a way a three-body system is not. We tend to call the latter unstable, & expect it over time to reach a stable state, like say a binary pair with a third in orbit so effectively two two-body systems. There will be gravity waves, tidal forces, stellar evolution, quantum indeterminacy etc etc but if those impacts are too small to impact the system we can treat it as deterministic, in the timespan of order the current age of the universe. Causal-closure is more useful an idea than determinism (nb: conservation of information) | |

| Apr 25, 2022 at 4:45 | comment | added | tkruse | So you have no such reference, and you are pushing your personal views. | |
| Apr 25, 2022 at 3:51 | comment | added | Pertti Ruismäki | Look up the definition of determinism. See, if you can find anything like that in reality. Experiment, try to sit somewhere without deciding where and when. | |
| Apr 25, 2022 at 2:58 | comment | added | tkruse | Do you have any reference for those claims? | |
| Apr 25, 2022 at 2:51 | comment | added | Pertti Ruismäki | There are no deterministic systems in reality. Nothing to sit on. In an imaginary deterministic system there could be no humans to sit on anything. Sitting is an act of free will, you have to decide where to sit and when. | |

| Apr 24, 2022 at 11:16 | comment | added | Pertti Ruismäki | No system could be partially deterministic. In a deterministic system there is nothing indeterministic and vice versa. | |
