Humans are born feeble little organisms in the midst of a vast, unknown universe, at a moment long after evolution began and long before it will cease. Here we exist in a tiny span of space and time. In the beginning we do not even know what questions to ask, or with what words to formulate them. We are like Don Quixote attacking windmills.
Science is our brazen challenge against the unknown.
The fantastic thing about this quest is the extent of its success. Humans can now trace their own history back for a million generations. We can describe with considerable reliability what is going on inside of stars. We have information about the structure and content of the universe out to a distance of 40,000,000,000,000,000,000,000 miles, and can analyze the detail of its parts down to a fine structure of 0.000,000,000,000,01 inch.
