Actually at the lowest level there's this whole quantum business that says exactly otherwise.

That is unlikely to affect the microscopic world. The physics of everyday life are deterministic, no need to invoke quantum mechanics.

GGGP didn't do that, they made a link with chaos theory and that's decidedly not deterministic.

And I think you meant to say 'macroscopic'.

GGGP?

And yes, I did mean macroscopic, sorry.
