In science, go means to move on a course; proceed; to move out of or away from a place; to take a certain course of follow a certain procedure; or to pass by means of a process like journeying. [1]
Maxwell
In 1834, at the age of three, to the inquisitive mind of James Maxwell everything that moved, shone, or made a noise drew the question:
“What's the go o' that?”
“What's the particular go o' that?”
“show me how it doos”
“The elements of living matter are identical with those of mineral bodies; and the fundamental laws of matter and motion apply as much to living matter as to mineral matter; but every living body is, as it were, a complicated piece of mechanism which ‘goes’, or lives only under certain conditions.”
“It is only because our lives are so short compared to the slow, slow movement of evolution, that it is hardly possible to notice the change and growth either in the earth or in ourselves. Because we never knew Italy to look anything other but a Wellington boot, we never pause to think that it was once different, and may change again. Because we never knew that time when man grew his own furry dress, we overlook the fact that, as he has outgrown this likeness to the animal, he may still outgrow others. Yet we must make our minds broad enough to realize the facts. The hour of a watch moves so slowly that you cannot see it move; and yet you know that, so long as the watch is going, its movement never stops. The earth, from its rocks and gases and flowers and animals, is still ‘going’.”— Hilda Finnemore (1924), A History of the Earth: from Stardust to Man (pgs. 56-57) [5]
