"Being a physicist does not require an encyclopedic knowledge of equations and fundamental constants coupled with the ability to perform complex arithmetic in one's head with robotic speed and precision. Physics is not about having memorized all the answers, but rather about asking the right questions. For when the right question is posed of a phenomenon, either the answer becomes clear, or at least the manner as to how one should go about obtaining the answer is revealed.
Scientific knowledge only comes at the price of increased doubt: the more we learn, the more clearly we see all that remains uncertain. Doubt is to be embraced in science, for only answers we can trust are those that survive the crucible of questioning and experimental testing." Tratto da The Physics of Superheroes.
