∆ (when the cities burn)

“Our civilization is flinging itself to pieces. Stand back from the centrifuge.” [Ray Bradbury, Fahrenheit 451] [note: in this case, ∆ (opt + j) is defined as it is in chemistry: ∆ = the addition of heat in a reaction and also references the general definition in math & science: ∆ = the change of any changeable quantity]
