/sci/ - Science & Math

Tell me /sci/, is solving a problem merely a question of duration? Could anyone solve any problem given enough time, or are some problems so complex that no amount could be enough?

If so, then what exactly is the reason for that?

Shouldn't any problem be reducible to simpler building blocks that in turn can be reduced even more, depending on the need of how low you need to go? So then if time isn't the only constraint, what else is there? Memory capacity that can only deal with so many blocks and concepts at once? Can a single such block/concept that can be reduced no more be too complex to understand?

If not, and if memory isn't a factor (whether it is or not in the first place, I'll leave open for discussion), shouldn't any problem be solvable with enough time, basically also implying that anyone can achieve anything intellectually given enough discipline (so that the only limiting factor becomes how much time and energy one can invest, which I know isn't limitless but still) and assuming at least average intelligence with no disabilities?
