Re: Definition of Free Will

Re: Unit of Time Travel

To measure nix, you would just need to know the amount of time that passed on one spaceship clock and one earth clock. Then you could take the ratio.

Just because you could say P ( givig you $20 | being at gunpoint ) > 0.5 does not mean they are not free, or does it? Should we just say that one is free "from X" if P(whatever | X) = P (whatever | not X) ?
