While officers from Army Ordnance, which owns ORDVAC, watched with admiration, the Illinois professors who built the machine fed problem after problem into its twinkling innards. ORDVAC added numbers at the rate of 10,000 per second. It finished twelve-digit problems in multiplication (e.g., 428,945,437,246 times 342,873,937,895) in one thousandth of a second. It did complex problems that required it to "remember" elaborate sets of instructions. It "generated" 352 random numbers and manipulated them in the subtle ways that delight mathematicians. One endurance test, involving floods of figures, took twelve hours. Every...
