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 plan must anticipate all that is needed Ebenezer Howard set spinning powerful and city-destroying ideas: He conceived that the way to deal with the city’s functions was to sort and sift out of the whole certain simple uses, and to arrange each of these in relative self-containment. And he conceived of good planning as a series of static acts; in each case the plan must anticipate all that is needed and be protected, after it is built, against any but the most minor subsequent changes.
