One might say science is the sum total of our knowledge of the universe, the great library of the known, but the practice of science happens at the border between the known and the unknown. Standing on the shoulders of giants, we peer into the darkness with eyes opened not in fear but in wonder.

We explore because we are curious, not because we wish to develop grand views of reality or better widgets.
