I wonder about that scientist. In theory, if you knew the state of everything, you could predict the future. But, Schroedinger showed you can not know the state of everything. Also, quantum mechanics kind of implies that the evolution of things (even at the lowest level) is probabilistic in nature. (Einstein's "Gott wuerfelt nicht." quote).
So quantum mechanics really seems to imply predestination exists only in terms of probabilities, which is pretty week.
I tend to follow Robert Anton Wilson's approach, which is consistent with quantum mechanics and very much anti-predestination.
I follow Sartre's concept of "you define yourself." It is the only thing that makes sense. You are not a passive punching bag for the universe.
