let's discuss..the human sciences..luck or curiosity

[spy4me]

Along the centuries, the human beings searched for cures, energy sources, alternative sources, other lives and maybe just for surviving, many things happened just by accident, and became the rules of our life, let's take the simplest example; Isaac Newton was taking a break under shady tree thinking about his day, when an apple fell on his head, since then, Newton made a lot of theories about natural phenomena. That incident is not just a symbol that refers to that great man, but also a strong proof about the human science source.

The question is : What led Newton to all that? His good luck or his wide curiosity?

What about the human sciences in general? Luck or curiosity?

If someone else, not Newton, was in the same situation, would it be the same?

Can we say that the discoveries, the inventions, fed on the curiosity of lucky men?
