The supreme task of the physicist is to arrive at those universal elementary laws from which the cosmos can be built up by pure deduction. There is no logical path to these laws; only intuition, resting on sympathetic understanding of experience, can reach them.

Never before have I lived through a storm like the one this night. … The sea has a look of indescribable grandeur, especially when the sun falls on it.
