Safety cut rope axe man In the first nuclear reactor, constructed by Enrico Fermi in 1942 under the bleachers of the University of Chicago football stadium, the control rods were held up by a manila rope. A man with an axe was told to cut the rope if the reactor got out of hand. This "safety cut rope axe man" is supposedly the origin of the term SCRAM for an emergency shutdown procedure.

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
