Well me and my friend were talking stuff on science in our dorm room once. And the topic of randomness came (kinda randomly), he said this same thing above as stated above on my original post, and from there I thought about this a bit more..
HAHa, nice reply anyway, my thoughts were random (random science stuff)! They were BUT BUT, they were random because we dont have any formula YET to predict what is coming from our head, if somehow I can put all our conversations of that night with my friend in a supposed formula then it may be possible to predect the next topic, but this is not possible for now...maybe after computation gets faster, better, stronger

(maybe, i dont want to speculate yes or no now)
However, I agree what you have said about "
there r things which r random and will remain random" because ultimately there will ALWAYS be a gap in our perception even if science advances. For example the classic theory of the buterfly effect.
If I rem correctly, present physicians are actually thinking of "discovering this formula" As Stephen Hawking puts it...its called the
Grand Unified Theory!
