“In the folklore of science, there is the often-told story of the moment of discovery: the quickening of the pulse, the spectral luminosity of ordinary facts, the overheated, standstill second when observations crystallize and fall together into patterns, like pieces of a kaleidoscope. The apple drops from the tree. The man jumps up from a bathtub; the slippery equation balances itself.
But there is another moment of discovery—its antithesis—that is rarely recorded: the discovery of failure. It is a moment that a scientist often encounters alone. A patient’s CT scan shows a relapsed lymphoma. A cell once killed by a drug begins to grow back. A child returns to the NCI with a headache.”
