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.

Begin with your work A Quote by Edward Tufte In doing creative work, do not start your day with addictive time-vampires such as The New York Times, email, and Twitter. All scatter the eye, and mind, produce diverting vague anxiety, clutter short-term memory. Instead, begin with your work. Many creative workers have independently discovered this principle. creativitywork
