Which half? One day when I was a junior medical student, a very important Boston surgeon visited the school and delivered a great treatise on a large number of patients who had undergone successful operations for vascular reconstruction. At the end of the lecture, a young student at the back of the room timidly asked, "Do you have any controls?" Well the great surgeon drew himself up to his full height, hit the desk, and said, "Do you mean did I not operate on half of the patients?" The hall grew very quiet then. The voice at the back of the room hesitantly replied, "Yes, that's what I had in mind." Then the visitor's fist really came down as he thundered, "Of course not. That would have doomed half of them to their death!" God, it was quiet then, and one could scarcely hear the small voice ask, "Which half?" E.E. Peacock Jr., Seeing With Fresh Eyes science
And thus the heart will break They mourn, but smile at length; and, smiling, mourn: The tree will wither long before it fall: The hull drives on, though mast and sail be torn; The roof-tree sinks, but moulders on the hall In massy hoariness; the ruined wall Stands when its wind-worn battlements are gone; The bars survive the captive they enthral; The day drags through though storms keep out the sun; And thus the heart will break, yet brokenly live on.
