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.

Infinite varieties of contexts Over the course of 10 years of using Are.na, I have fully adopted the view that any piece of information can be important to a person given the right context. And on Are.na, pieces of information can be arranged in infinite varieties of contexts – their respective meaning shifts as the proximate information shifts. In other words, the more connections a block has, the more opportunities it has to be a nodal point.
