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
The beauty of odd numbers Kasuri is thus a textile that appears to have been rubbed. Since the edges of the pattern do not align, they take on the nature of an odd number rather than an even number. Without this rubbing or smudging, kasuri could never have been. However, since it is precisely this misalignment and blurry effect that is the source of kasuri’s beauty, we are presented with an interesting problem. I will call this problem ‘the beauty of odd numbers’. Yanagi Sōetsu, The Beauty of Kasuri The Japanese Perspective numberseuphony
