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.

Bells Most Japanese bells when hung still have on them one or more rough lines obviously arising in horizontal mold joints. These lines are not removed in fettling the bell, and they seem to be regarded not as defects but rather as a reminder of the reality of the founder’s interaction with his materials. One is reminded of the ceramics that are most treasured in Japan which usually have some unexpected tool marks or irregularity resulting from a kiln mishap.
