      Nordsieck’s Differential Analyzer - CHM Revolution
      Nordsieck's Differential AnalyzerUsing $700 worth of surplus World War II supplies, Arnold Nordsieck assembled an analog computer in 1950. It was modeled on differential analyzers built since the 1930s—but with key differences.For instance, Nordsieck’s computer used electrical connections instead of mechanical shafts. And he set himself the priorities of “convenience and simplicity…portability, and economy.” His device’s small size and straightforward engineering satisfied the first three requirements. Its $700 price tag satisfied the fourth.
