Timeline for If I drop a leaf twice from the height of a tree in a completely controlled environment, will the trajectory in each case be the same?

| Apr 4, 2014 at 8:24 | comment | added | Benjamin Toueg | @cHao What I mean is that if we were rolling the dice once again, with the exact same initial conditions, are we sure matter would have won over antimatter? If not, then the question is closed. | |
| Apr 4, 2014 at 2:43 | comment | added | Chris Mueller | @ja72 True, but the lack of determinism comes from quantum mechanics, not from the fact that the system is chaotic. | |

| Apr 4, 2014 at 1:25 | comment | added | cHao | @BenjaminToueg: Because we're on the winning team? :) The two have trouble coexisting, so one of them has to win out. And if anti-matter had won, it'd be the norm, we'd be made of it, and we'd be calling it "matter" -- and the matter we currently know and love would be the "anti-matter". | |

You need both positions and momenta to completely define initial conditions, which you cannot. There are multiple initial conditions, all superimposed onto each other. | |

| Apr 3, 2014 at 19:16 | comment | added | Chris Mueller | @ja72 Chaos theory is the study of systems whose outcomes are very sensitive to the initial conditions. The systems of study can still be fully deterministic though. | |

| Apr 3, 2014 at 18:59 | comment | added | wgrenard | The uncertainty principle, as far as we understand it, is not 'uncertain' for the reason that our knowledge is incomplete, as you state. Rather, the uncertainty lies in the fact that a particle really has no definite position and momentum at a given time | |
| Apr 3, 2014 at 18:55 | comment | added | John Alexiou | Nope, because of Chaos Theory. Determinism is a fallacy. | |
